Zakale, m'magalimoto kumbuyo kwa hatchback ndi station wagon, tailgate imatsegulidwa mmwamba.Komabe, pamenepa, pali vuto lotsegula chitseko.Vutoli limathetsedwa bwino ndi zotulutsa mpweya - werengani za magawo awa, mawonekedwe awo, kukonza ndi kukonza m'nkhaniyi.
Cholinga cha zotsekera khomo lakumbuyo
Magalimoto ambiri apakhomo ndi akunja kumbuyo kwa hatchback ndi station wagon ali ndi tailgate yomwe imatsegula mmwamba.Njira yothetsera vutoli ndiyosavuta komanso yabwino kwambiri, chifukwa mutha kugwiritsa ntchito mahinji omwewo kuti mutsegule chitseko, ndipo chitseko chokhacho chimakhala chosavuta kulinganiza kuposa ngati chitsegulidwe cham'mbali.Kumbali ina, kutsegula tailgate m'mwamba kumafuna njira zapadera kuti zitsimikizire chitonthozo ndi chitetezo.Choyamba, m'pofunika kuonetsetsa kuti chitseko chikugwira bwino pa malo apamwamba, komanso kuthandizira kutsegula chitseko kwa anthu afupipafupi.Ntchito zonsezi zimathetsedwa mothandizidwa ndi ma shock absorbers a tailgate.
Chotsitsa cha tailgate shock (kapena choyimitsa mpweya) ndi chipangizo cha pneumatic kapena hydropneumatic chomwe chimathetsa ntchito zingapo:
- Thandizo potsegula chitseko - choyimitsa chodzidzimutsa chimangokweza chitseko, kupulumutsa mphamvu za eni galimoto;
- Kuwonongeka kwa kugwedezeka ndi kugwedezeka pamene chitseko chakumbuyo chatsegulidwa ndikutsekedwa kwathunthu - gawolo limalepheretsa kugwedezeka komwe kumachitika pamene chitseko chikukwezedwa ndikutsitsidwa kumalo okwera kwambiri;
- Kuonetsetsa chitetezo pamene chitseko chatseguka - chotsitsa chododometsa chimasunga chitseko pamalo apamwamba popanda kugwiritsa ntchito zowonjezera zowonjezera, kuteteza kuti zisatseke pansi pa kulemera kwake kapena katundu wofooka wa mphepo;
- Chitetezo cha chitseko chakumbuyo, zinthu zosindikizira ndi zida zagalimoto yamagalimoto kuti zisawonongeke ndikuwonongeka chitseko chikatsekedwa.
Koma chofunika kwambiri, tailgate shock absorber imawonjezera chitonthozo cha galimoto, chifukwa imakulolani kuti mutsegule mosavuta ndi kutseka thunthu ngakhale ndi manja anu odzaza, nyengo yozizira, pamene galimotoyo ili yonyansa, etc. Choncho, tailgate shock absorber ndi gawo lofunika la galimoto, zomwe zimapangitsa kuti zikhale zosavuta, zomasuka komanso zotetezeka.
Mitundu, chipangizo ndi ntchito ya shock absorbers (maima) a khomo lakumbuyo
Pakadali pano, mitundu iwiri ya tailgate shock absorbers imagwiritsidwa ntchito:
- Pneumatic (kapena gasi);
- Hydropneumatic (kapena gasi-mafuta).
Zodzikongoletsera izi zimasiyana pamapangidwe ndi mawonekedwe a ntchito:
- Kuchepetsa mphamvu kumayendetsedwa mu pneumatic (gasi) shock absorbers;
- Mu hydropneumatic (gasi-mafuta) zotsekemera zotsekemera, hydraulic damping imayendetsedwa.
N'zosavuta kumvetsetsa kusiyana kwa mitundu iyi ya zipangizo, ndikwanira kusokoneza dongosolo lawo ndi mfundo ntchito.
Mitundu yonse iwiri ya ma shock absorbers imakhala ndi mapangidwe ofanana.Iwo zachokera yamphamvu wodzazidwa nayitrogeni pansi mokwanira mkulu kuthamanga.Mkati mwa silindayo muli pisitoni yolumikizidwa mwamphamvu ndi ndodo.Ndodoyo imatulutsidwa kudzera pagulu la gland - imagwira ntchito zonse zopaka ndodo ndikusindikiza silinda.Pakati pa silinda, m'makoma ake, pali njira za gasi zazing'ono zodutsamo, zomwe mpweya wochokera pamwamba pa pisitoni umatha kulowa mumlengalenga wa pistoni ndi mbali ina.
Palibenso china chilichonse mu chotsitsa cha gasi, ndipo mu chotengera cha hydropneumatic shock, pambali ya ndodo, pali posamba mafuta.Komanso pisitoni ili ndi zosiyana - ili ndi mavavu.Ndi kukhalapo kwa mafuta komwe kumapereka hydraulic damping, zomwe zidzakambidwe pansipa.
The pneumatic shock absorber ya tailgate ili ndi mfundo yosavuta yogwiritsira ntchito.Chitseko chikatsekedwa, chotsitsa chododometsa chimatsindikizidwa, ndipo m'chipinda chapamwamba cha pisitoni pali mpweya waukulu wothamanga kwambiri.Mukatsegula chitseko chakumbuyo, kupanikizika kwa gasi sikulinso moyenera ndi loko, kumaposa kulemera kwa chitseko - chifukwa chake, pisitoni imatulutsidwa, ndipo chitseko chimatuluka bwino.Pistoni ikafika pakatikati pa silinda, njira imatseguka pomwe mpweya umalowa m'chipinda china (pistoni).Kupanikizika m'chipinda chino kumawonjezeka, choncho pisitoni imachepa pang'onopang'ono ndipo kuthamanga kwa chitseko kumachepa.Pamene nsonga yapamwamba ikufika, chitseko chimayima kwathunthu, ndipo zotsatira zake zimachepetsedwa ndi "khushoni" ya mpweya yomwe imapanga pansi pa pisitoni.
Kutseka chitseko, chiyenera kugwetsedwa pansi ndi dzanja - pamenepa, pisitoni idzatsegulanso njira za gasi panthawi yake, gawo lina la gasi lidzalowa m'malo a pisitoni pamwamba, ndipo chitseko chikatsekedwa mopitirira. idzachepa ndi kudziunjikira mphamvu zofunikira pakutsegula kwa chitseko chotsatira.
Chotsitsa chamafuta chimagwiranso ntchito chimodzimodzi, koma ikafika pamwamba, pisitoni imamizidwa mumafuta, motero imatsitsa mphamvuyo.Komanso mu chotsitsa chododometsa ichi, mpweya umayenda pakati pa zipinda mosiyana pang'ono, koma palibe kusiyana kwa kardinali kuchokera ku pneumatic shock absorber mmenemo.
Monga tanenera kale, zomwe zimatchedwa damping damping zimagwiritsidwa ntchito poyimitsa mpweya wa pneumatic.Zimasonyezedwa ndi chakuti kuthamanga kwa kutsegula chitseko kumachepetsa pang'onopang'ono kuyambira pachiyambi cha pisitoni kupita kumtunda, ndipo chitseko chimabwera pamwamba pamtunda wochepa.Ndiko kuti, nkhonyayo imachepetsedwa osati pamapeto omaliza kutsegula chitseko, koma ngati kuzimitsidwa mu gawo lonse la magalimoto.
Kudontha kwa hydraulic kuli ndi kusiyana kwakukulu: kukhudzidwa kumangonyowetsedwa pagawo lomaliza la chitseko chotsegulira pomiza pisitoni mumafuta.Pachifukwa ichi, chitseko cha gawo lonse la njira chimatsegulidwa pamtunda komanso pafupifupi liwiro lomwelo, ndipo chimaphwanyidwa pokhapokha asanafike pamwamba.
Mapangidwe ndi mawonekedwe a kukhazikitsa kwa gasi kuyimitsidwa kwa chitseko chakumbuyo
Mitundu yonse iwiri ya ma shock absorbers ili ndi mapangidwe ndi mapangidwe ofanana.Ndi silinda (yomwe nthawi zambiri imapakidwa utoto wakuda kuti zitheke komanso kuzizindikiritsa mosavuta) pomwe pamakhala tsinde lopukutidwa ndi galasi.Pamapeto otsekedwa a silinda ndi ndodo, zomangira zimapangidwira kuti zikwere pakhomo ndi thupi.Zodzikongoletsera zimayikidwa zomangika, mothandizidwa ndi zikhomo za mpira, zoponderezedwa kapena zokhazikika pazothandizira zoyenera kumapeto kwa chotsitsa chododometsa.Kuyika zikhomo za mpira pa thupi ndi pakhomo - kupyolera mabowo kapena mabatani apadera okhala ndi mtedza (zingwe zimaperekedwa pa zala za izi).
Shock absorbers, kutengera mtundu, ali ndi mawonekedwe oyika.Pneumatic-mtundu shock absorbers (gasi) akhoza kuikidwa pamalo aliwonse, popeza kuyang'ana mumlengalenga sikukhudza ntchito yawo.Ma hydropneumatic shock absorbers amatha kukhazikitsidwa ndi tsinde pansi, chifukwa mafuta ayenera kukhala pamwamba pa pisitoni, zomwe zimatsimikizira mikhalidwe yabwino kwambiri.
Kukonza ndi kukonza ma tailgate shock absorbers
Zitseko zam'mbuyo zam'mbuyo sizifuna chisamaliro chapadera panthawi yonse yautumiki.Ndikofunikira kuyang'ana nthawi ndi nthawi magawowa kuti atsimikizire kukhulupirika kwawo ndikuwunika mawonekedwe amafuta amafuta (ngati ndi hydropneumatic shock absorber).Ngati chiwopsezo chapezeka ndipo pali kuwonongeka kwa ntchito ya chotsitsa chododometsa (sichimakweza chitseko bwino, sichitsitsa kugwedezeka, etc.), ndiye chiyenera kusinthidwa pamsonkhano.
Kusintha kwa shock absorber nthawi zambiri kumabwera motere:
1.Kwezani tailgate, onetsetsani kusungidwa kwake ndi kuyimitsa kwina;
2.Tsukani mtedza uwiri womwe uli ndi zikhomo za mpira wa shock absorber, chotsani kugwedeza;
3.Ikani chotsitsa chatsopano chododometsa, onetsetsani kuti chili cholondola (tsinde kapena ndodo pansi, malingana ndi mtundu);
4.Limbani mtedza ndi mphamvu yovomerezeka.
Kutalikitsa moyo wa absorbers mantha ndi kuonjezera moyo wawo, muyenera kutsatira malangizo ochepa osavuta opaleshoni.Makamaka, simuyenera "kuwathandiza" kukweza chitseko, simuyenera kukweza chitseko ndi kukankhira mwamphamvu, chifukwa izi zingayambitse kusweka.M'nyengo yozizira, muyenera kutsegula tailgate mosamala, koposa zonse mutatha kutenthetsa kanyumba, popeza zotulutsa mantha zimaundana ndikugwira ntchito moyipa kwambiri.Ndipo, ndithudi, sikuloledwa kusokoneza zigawozi, kuziponya pamoto, kuziyika ku nkhonya zamphamvu, ndi zina zotero.
Ndi ntchito mosamala, tailgate shock absorber idzagwira ntchito kwa nthawi yayitali komanso modalirika, ndikupangitsa galimotoyo kukhala yomasuka komanso yosavuta muzochitika zosiyanasiyana.
