Te wiriwiri o te tima me te whakaora i te hiku ika i te wa e toia ana: te tikanga whakahaere pakaru me te ahupūngao taumaha arero¶

Ko te toia i te waka tere, te poti, te waka waka whaipainga, te waka waka hoiho ranei ka whakaurua he tohu hinge (te poi hitch) kei muri i te toki o muri o te waka. I runga ake i te tere o te paepae huanui, te tikanga kei waenga i te 85 me te 105 kiromita ia haora (53 me te 65 maero ia haora), he whakararuraru i te taha taha mai i te ngaru kopere ahua-taraka e pahemo ana, he awha kaha o te hau, he hekenga heke, he waka toi kore tika ranei me te iti o te taumaha o te arero ka taea e ia te whakahihiri i te kaha o te arero, na te mea ka taea e ia te whakahihiri i a ia ano. (te nakahi, te hiku ika ranei)**. I te wa ka timata te haruru o te wakatō, ka huri te pendulum ki ia hurihanga, ka whiu i te parepare o muri o te waka toia ki te taha maui me te taha matau kia huri ra ano te rig ki nga huarahi waka katoa i roto i te iti iho i te rima hēkona.

Kia ora ai koe i te tere tere o te waka tauaru, me kaha ki te ako i nga mahi a-ringa: ko te hurihanga a te tangata ki te tukituki i te whati waewae o te waka, ka kite ranei i te urungi whakamuri me te whakamuri ka huri te taumaha ki mua ki runga i te poro hitch me te whakakaha ake i te pendulum ki te maripi jack. Engari, me pupuri tonu te taraiwa i te wira urungi, tangohia rawatia o ratou waewae ki waho i te whakatere me te peera waka, ka tono anake nga perei hiko motuhake o te wakatō ma te whakamahi i te riipene a-ringa/whakawiri whakawiri i runga i te papatohu wakatō perehi mana whakahaere ki te toia te riu kua whakamarohia ano he aho totoro.

Mahia tenei inaianei¶

1. Tangohia to waewae ki waho i te peera me te whakatere tere o te waka: Ina ka rongo koe e wiri ana te wakatō i te pito o muri o to taraka, SUV ranei mai i tetahi taha ki tetahi taha, whakaarahia to waewae matau mai i te peera hau kia mutu ai te taapiri i te kaha o te hikoi, me te ** kia mau to waewae ki waho o te pedal frein matua o te waka**. Ko te tukituki i nga rekereke waewae o te waka ka puhoi te waka o mua i te wa e tere haere whakamua ana te wakatō taumaha kei muri i a koe i runga i te tere huanui, ka pana tahataha ki to parepare o muri, ka takai i te rig ki te maripi jack.
2. Kia mau te urungi ka mate tika i te 9 me te 3 karaka: Maukati o tuke ka mau tonu te urungi ki raro i te waenganui o to huarahi. Kaua rawa e ngana ki te "whakarere i waho" ki te tarai ranei i te taraiwa wakaaa; na te waahi o te wa i waenganui i ou potae o mua me te toka wakatō 8 mita (26 putu) i muri i a koe, ka huri te urungi i te wa me nga piu ka pa ki te auau haruru, ka ruarua te tutu o te piu hiku ika.
3. Pitihia te rei whakawiri a-ringa i runga i to kaitahuri wakarere: Totoro ki raro ma te ringa kotahi ki to papatohu kua eke Kaiwhakahaere Pereera Tere Hiko ka pehia marietia (ka paheke ranei) te whakarerea a-ringa / pae whakawiri 50 ki te 75 paiheneti o te huarahi puta noa. Ka uru tenei anake nga perehi hiko i runga i nga wira o te wakatō me te kore e pakaru i te waka toia, ka hanga te toia whakamuri i muri i te poi hitch e toro tonu ana te wakatō ki te tirohanga ki muri o te taraka.
4. Mena kei te toia te waka waka kaore he perehi hiko (he perehi kare ranei), takutai tika ki raro i te tere: Mena kei te toia e koe he taputapu, waka waka waka ranei e mau ana ki nga perei waipēhi, karekau ranei he perei wakatō, kia mau tonu te urungi i te toka ki mua, kia mau to waewae ki mua i nga perei motoka, kia toia te miihini me te aatete hau kia whakaroa te riu ki raro i te paepae o te 40 kiromita i raro i te 40 km/h. ka makuku noa iho te oscillation.
5. Kua ki runga i te pakihiwi whanui, taumata ka mutu te tere ka mutu te wiri: I muri noa i te whai a te wakatō i te 100 paiheneti tika me te heke o to tere ki raro i te 50 ki te 60 km/h (30 ki te 37 mph), tono marietia te braking noa, te tohu, me te ngawari ki runga i te pakihiwi whariki whanui me te waahi okiokinga huanui. Mena kua pa mai he tukinga, he hurihanga ranei, waea atu ki to nama whawhati tata (911 i Amerika me Kanata, 112 puta noa i te Kotahitanga o Europi, 999 i te United Kingdom) tirohia ranei tau ohorere.
6. Kaua rawa e whakaara ano i te tere huanui me te kore e whakatika i te tohatoha taumaha o te wakatō: Karekau rawa te haruru o te waka tereina i te ohorere; ko te tikanga he hiku-taimaha to wakatō (he iti te taumaha o te arero i raro i te 10 paiheneti), he pahekeheke te pehanga o to tupare, he wetewete ranei o toha-tuha-maha/a-a-te-waa. I mua i te taraiwa i tetahi atu kiromita, nekehia nga pouaka utanga taumaha ki mua i te toki wakatō me te whakaheke i to tere tere ma te iti rawa 15 ki te 20 km/h (10 ki te 15 mph).

Ahupūngao o te pendulum toi-rua-papatipu me te tere o te wiri arohaehae¶

Kia mohio ai koe he aha te tere o te tere tere i te 85 km/h (53 mph) ka pahū ohorere ki roto i te hiku o te ika i te 100 km/h (62 mph), me mohio koe ki te tere o te waka o te punaha papatipu-rua:

1. Pai me te toraro te whakaheke me te Tere Tino (\(V_{crit}\))¶

Ka toia te wakatō ki raro i te huanui, ka peia te hiku o te wakatō ki te taha maui, ki te taha matau ranei, ka pana te hiku o te wakatō ki te taha maui, ki te taha matau ranei, ka puta he ** koki yaw** huri noa i te poi here.

• Kei raro i te Tere Tino (Poitive Damping): I te tere tere, na te maro o te taha taha o nga potae wakatō ka turaki i te wakatō ki te raina waenga me te iti ake o te kaha i te putunga tuatahi. Ka wiriwiri te wakatō kotahi, e rua ranei, ka tau totika (te remu pai).
• Kei runga ake i te Tere Tino (Damping Negative / Self-Excitation): I te pikinga o te tere o te rori, ka piki te toia aerodynamic me te torohaki whakamua me te tapawha o te tere (\(v2\)). Ko ia huinga tow-waka-a-trailer he momo pangarau ** Tere Tino (\(V_{crit}\))** ka heke te remu ki te kore, ka huri kino. Kei runga ake i te \(V_{crit}\), ka puta mai nga potae wakatō i te kaha o te taha taha ki te mahanga i te wakatō whakamuri ki te pokapu, ka toro atu te wakatō i te raina waenga me te kaha ake te kaha neke atu i te putunga taketake. Ko te piu 1 he 15 henimita (6 inihi); Ko te piu 2 he 60 henemita (2 putu); Ko te piu 3 he 2 mita (6.5 putu), ka whiua te tuaka o muri o te waka toia ki te taha o te papa.

2. He aha te tukituki i nga pereki waka ka puta he maripi jack¶

Whakaarohia to waka toka me to wakatō hei poraka taumaha e rua e honoa ana e te inihi pivoting:

• Kopeketanga i runga i te poi hiri (Foot Brake = Jackknife): Ka paopao koe ki te whati waewae matua o te waka, ka heke te tere o te waka o mua ki te \(0.6g\) ki te \(0.8g\) i te wa e pana whakamua ana te waka toona-maha i muri ki te poi hitch me nga mano o nga newtons o te kaha kōpeke. Mena he 5 nga nekehanga kei waho o te raina i te wa e pa ana koe ki te pakaru o te waewae, ka mahi taua pana whakamua hei ringa tuara hei pana i te parepare o muri o to taraka ki te taha, ka whakakopa i te taraka me te wakatō ano he maripi pukoro (jackknifing).
• Te taumahatanga i runga i te poi uwhi (Tukuhia te Parai Reru A-ringa = Raina Tika): He rerekee, ka waiho e koe te parai waewae o te taraka kia kaua e pa, ka pehia anake ko te rei whakawiri a-ringa i runga i te papatohu wakatō perehi mana whakahaere, ko te pahū hiko o te wakatō me te parai kōpae ka mau ki raro. Inaianei kei te toia te wakatō whakamuri ki te poi hitch i roto i te te maataki noa i te wa e anga whakamua tonu ana te taraka, ka totoro totika te hii here ki waho penei i te toia i nga pito e rua o te mekameka piko.

Pūnaha parai waka me te matrix whakaora ohorere¶

I mua i to kumea ki runga i te huarahi nui me te wakatō, tautohu ko wai o nga punaha tarai waka e wha e whakamahia ana e to riu kia mohio ai o ringaringa ki te mahi i te ohorere:

Te ahupūngao taumaha o te arero: he aha te take o te uta-tamaha o te hiku ka mate¶

I roto i nga hanganga tukinga huanui e whakahaeretia ana e te National Highway Traffic Safety Administration (NHTSA) me te SAE International, kaore i te tika te tohatoha i te taumaha o te wakatō, inaa ka iti te taumaha o te Arero (TW), ko te #1 te take o te hurihanga o te wakatere mate.

Ko te ture koura 10% ki te 15% Taumaha arero¶

• He aha te Taumaha o te Arero: Ko te Taumaha arero ko te topa poutū poutū whakararo ka tukuna tikatia e te kaihono wakatō ki runga i te poi uwhi o te waka toia ina utaina katoatia.
• Ko te ōrau e hiahiatia ana mo nga hiwi kume parepare noa: Mo nga waka rererangi kua eke ki runga poi (rewa haere, waka waka, kaikawe waka), Me noho te taumaha o te arero i waenga i te 10 paiheneti me te 15 paiheneti o te Taumaha Arata Kato (GTW) (me 15% ki te 25% mo nga wira me te kuihi tuarima). Hei tauira, me whai 270 ki te 405 kirokaramu (600 ki te 900 pauna) te taumaha whakararo o te 2,700 kirokaramu (6,000-pauna) te utaina i runga i te poi hitch.
• He aha te uta-taimaha o te hiku (< 10% Taumaha arero) ka huri i te wakatō ki roto i te taiwhanga koretake:
• Ina utaina nga utanga taumaha (pouaka taputapu, miihini, motopaika, taika wai, wahie ranei) i roto i te ** haurua o muri o te wakatō i muri i te toki o te wakatō**, ka rite te taumahatanga o muri ki te hio ka hikina whakarunga ki runga i te arero wakatō o mua, ka whakaiti i te taumaha o te arero ki raro i te 8 paihēneti (ranei te hanga hiki kino).
• Ko te neke i te pokapu o te papatipu o te wakatō i muri i tana toki ka tino whakahekehia te Tere Huriwei Nui o te wakatō (\(V_{crit}\)) mai i te 120 km/h (75 mph) ki raro ki te 75 km/h (47 mph) me te neke i te pokapū o te hurihanga i muri i te toki kia taea ai e ia taha-ki-te-taha te piu nui ki waho o te toi kaha ki waho o te kaha o te taiapa nui.

Te whakatikatika i to mana whakahaere parai waka waka hiko i mua i te haerenga¶

Karekau he painga o te kaiwhakahaere perei wakatō hiko i roto i te ohotata hiku ki te mea ka iti rawa tana Whiti (Power Output) ka iti rawa te kapo mai o te perei wakatō, he tiketike ranei ka pa atu ki te tuara ka maukati nga potae wakatō ki roto i te mokowhiti hikareti (he raka, he pohehe kare te tupare ka ngaro te 100 paiheneti o tana toronga taha taha ka paheke ki te taha o te karauna o te huarahi).

30-hekona te waahi waka Tuhia te tikanga whakatikatika¶

I nga wa katoa ka mau koe i tetahi wakatō, ka huri ranei i tana uta uta, whakatairitehia to kaitahuri parai i roto i te tohanga papaa kau, torotika i te 40 km/h (25 mph):

1. Tautuhia te Whiwhinga tuatahi ki waenganui (hei tauira, 5.0 ranei 6.0 i runga i te tauine mamati 1-ki-10).
2. Kia tere ki te 40 km/h (25 mph) i roto i te raina tika, tuku te hau, ka pehia te manual override pinch lever (100 ōrau) mā te ringa.
3. Whakatikahia te Whiwhinga ki raro tonu i te maukati wira:
4. Ki te raka nga wira wakatō, ka tangi, ka tangi ranei i runga i te paparanga maroke, he tiketike rawa to Paanga; tahuri a Gain ki raro 0.5 ka piki kia kore ra ano nga wira e kati.
5. Mēnā ka pōturi haere te rig ina ka kowhakina katoatia e koe te reihi, tahuri a Gain ki runga 0.5 ka piki ake ra ano kia kaha koe, he whakahekenga mai i te wakatō me te kore e kati nga potae.
6. Whakatika i te Whiwhinga mo te ua nui, te Hukarere ranei: I runga i nga huarahi makuku, tio ranei, whakahurihia te Paanga o to kaiwhakahaere ki raro. 1.0 ki 2.0 tohu kia kore e maukatihia e te ringaringa ohotata nga potae wakatō ki runga i te papa kirikiri.

Te whakaora ohorere mai i te heke o te wira-matau i waho o te huarahi, i te pakaru ranei o nga potae wakatō¶

E rua atu nga ohorere o te huarahi nui e whakaohooho ana i te ngangau kino:

1. Ina taka nga potae matau o te wakatō i te taha o te pakihiwi whariki¶

Mēnā ka panaia e te hau whakawhiti tō wakatō ki runga i te raina kohu ma kia taka ai ona tupare taha matau ki runga i te pakihiwi kirikiri raro me te ngutu uku 5-ki-10-henemita (2-ki-4-inihi):

• Kaua rawa e whakakorikoria te urungi ki te maui ki te whakahoki i te wakatō ki runga i te papa i runga i te huarahi tere tere: Ko te horoi i nga potae wakatō ki te taha taha ki te ngutu uku poutū tae noa ki te ekenga ohorere ki te papaahi ka whakarewahia te wakatō puta noa i te huarahi i roto i te whiunga pendulum tutu e kiia nei he "whakaora titaha."
• Engari: Taia marietia te taha o te papa, whakamaua atu i te katereti, paopao ngawari i te tauera whakawiri parai wakatō a-ringa mena ka kumea te wakatō ki te taha matau, ka whakaroa ki raro 40 km/h (25 mph) i mua i te urungi ki te huanui i te koki 15-ki-20-tohu kia maeneene ai nga potae ki te kore e eke ki runga.

2. Ka pupuhi nga tupare waka i te tere o te huarahi¶

I te wa e pupuhi ana tetahi tupare i runga i te toka kotahi, i te toka-axle ranei, i te 100 km/h (62 mph), ka puta mai te tohanga hangarite ohorere ki tetahi taha o te tira:

1. Purihia te urungi ki nga ringa e rua, kaua hoki e tukituki i te waahi waewae.
2. Hoatuhia te 25 ki te 40 paihēneti te tauera whakawiri parani wakatō a-ringa anake mena ka timata te wakatō ki te wiri taha-ki-te-taha, me te tuku i te miihini ki te whakaheke i te riu ki to ara.
3. Te takutai i raro i te 35 km/h (22 mph) i mua i te huri ki runga i te pakihiwi kia kore ai te riu o te potae e pupuhi ana e keri ki roto i te paru pakihiwi ngohengohe ka huri i te wakatō.

I mua i te wehenga atu, 5-ira te rarangi arowhai aukati¶

I mua i te hoki whakamuri ki runga i te huarahi i muri i te mataku, tirohia enei tautuhinga miihini e rima i te taha rori:

1. Te tuunga utanga ("60% ki mua i te toki wakatō"): Whakanukuhia nga pouaka whakamatao, pouaka taputapu, potae waapa, me nga tueke ki mua o nga toki wakatō. Mena kei te toia he RV me nga taika wai, ruia nga taika wai para hina/pango o muri, ka taapiri wai ranei ki te puna hou o mua mena kei te tata ki te arero.
2. Te pehanga pikinga o nga potae waka me te tuara (Cold PSI): He ngohe nga taiapa o te taha o te taiapa, he kopikopiko te ahua o te tiēre i te wa o te hau. Whakanuia nga potae taraiwa katoa ki te PSI Makariri teitei i whakarewahia i runga i te pakitara taha tupa wakatō (motuhake STKo nga potae taraiwa kua whakatauhia ko te 345 ki te 550 kiropascals / 50 ki te 80 psi), me te pupuhi i nga potae o muri o to waka ki runga i te reanga kawenga morahi.
3. Te teitei o te whiri (Taumata, 2 cm / 1 i te ihu-whakararo): Tu whakamuri 10 mita (30 putu) ki te papa papatahi ka titiro ki te anga waka waka. Me noho te anga tauaru whakatairitea ki te papaahi, kia tio rawa ranei te ihu ki raro. Ka toia te ihu o te wakatō (na te mea he tiketike rawa te ekenga o te poroporo) ka huri whakamuri te taumaha ki runga i te parepare o muri o te wakatō me te whakapouri nui.
4. Taurere waku me te Weight-Distribution Hitch (WDH) te ahotea: Mena kei te whakamahi koe i te whiri toha-taimaha me nga kaera puna / porowhita, he pae wiri waku ka taea ranei te whakarite, whakapaa te kakau waku kia kotahi te huri a karaka, whakanekehia ranei te mekameka WDH ki runga kotahi hono ki te whakahoki i te waku whakamarumaru aukati.
5. Tirohia te taura o te taura ohotata: Manatokohia ko te rino angiangi tauera whawhati tata (e kumea ana he titi ki te arero o te wakatō ki te maukati i nga perei hiko o te wakatō ma te whakamahi i te pākahiko wakatō o runga mena ka wetekina te whiri) kua herea mau ki tetahi anga paiherea i runga i to taraka, **kaore rawa e whiria ki runga i te poi hiko o te wakatō-2 kua pakaru.

Te ora ohorere ki te wehe te wakatō, ka wehe ranei i te tere tere¶

I etahi wa, ka kitea e te rukenga poutū, te haruru wakatō ranei he hononga poipoi hee te whiri (kei te noho te kauae hono ki runga ake o te poi whiri, kaua ki te rawhi i raro, ka whakamahia ranei he poi iti 1-⅞-inihi i roto i te 2-inihi, 2-5/16-inihi ranei. Ka puta te arero o te wakatō mai i te pōro uwhi i te 100 km/h (62 mph), ka taka te wakatō ki runga i ona mekameka haumaru whiti, ka tuki kaha ki muri o te waka:

1. Ko nga mekameka haumaru kua whiti hei pouraka maitai i raro i te arero: Ko nga ture toia a Federal me te ao e hiahia ana kia rua nga mekameka haumaru rino taumaha kia whakawhitia ki te tauira "X" i raro i te arero wakatō me te whakaroa noa kia taea te huri koi. Ina whiti tika, ki te peke atu te kaihonohono mai i te poi whakawiri i te tere o te huarahi, ka tau te arero o te wakatō topa ki roto i te pouraka whiti o nga mekameka, kaua ki te keri i tana pou tiihi rino ki roto i te parapara ano he pou-pou, ka huri i te mutunga o te wakatō.
2. Me pehea te Whakawhiti Breakaway e aukati ai i te wakatō parani karekau i honoa: Ki te kore rawa te hono e rua me nga mekameka haumaru, ka toia e te maitai angiangi tauera whiti whati* te titi kume kirihou ki waho o te pouaka whakawhiti wehe o te wakatō. Ka hono tenei i te pākahiko 12-volt o runga o te wakatō ki nga aukume parai hiko i te 100 paihēneti ngaohiko, ka maukati i nga perei o te wakatō kia tu ki te raina tika i muri i a koe.
3. Ko te whakaora a te taraiwa i te wa e eke ana te arero ki runga i nga mekameka haumaru: Mena ka puta te kaihonohono i te poi engari kei te herea tonu te wakatō ki to parepare e nga mekameka whakamarumaru, kaua e patiki i nga rekereke waewae o to taraka (ma te mea ka rere totika te arero o te tira tira kore i roto i to hiku, i te parepare o muri ranei). Purihia te wira urungi kia mate tika, kotohehia te manual trailer brake controller pinch lever kia mau tonu nga perei hiko o te wakatō i te wakatō i runga i to parepare i roto i te taumahatanga, ka whiti ki raro ki te tu marie i te raina tika.
