Mfundo ya Twin Tube Shock Absorber (Mafuta + Gasi)

Kuti mudziwe bwino za twin tube shock absorber yomwe ikugwira ntchito, lolani kaye kamangidwe kake. Chonde onani chithunzi 1. Mapangidwewa angatithandize kuwona twin tube shock absorber momveka bwino komanso mwachindunji.

Chithunzi 1: Mapangidwe a Twin Tube Shock Absorber

The shock absorber ili ndi zipinda zitatu zogwirira ntchito ndi ma valve anayi. Onani tsatanetsatane wa chithunzi 2.
Zigawo zitatu zogwirira ntchito:
1. Chipinda chapamwamba chogwirira ntchito: gawo lapamwamba la pisitoni, lomwe limatchedwanso chipinda chothamanga kwambiri.
2. Chipinda chogwiritsira ntchito pansi: gawo lapansi la pisitoni.
3. Malo osungiramo mafuta: Ma valve anayi amaphatikizapo valavu yothamanga, valavu yobwereranso, valavu yobwezera ndi mtengo woponderezedwa. Valve yothamanga ndi valve yobwereranso imayikidwa pa ndodo ya pistoni; iwo ndi zigawo za pisitoni ndodo zigawo. Valve yolipirira ndi mtengo wopondereza amayikidwa pampando wa valve; ndi zigawo za zigawo zapampando wa vavu.

Chithunzi 2: Zipinda zogwirira ntchito ndi mfundo zake za Shock absorber

Njira ziwiri za shock absorber zimagwira ntchito:

1. Kuponderezana
Ndodo ya pistoni ya shock absorber imayenda kuchokera pamwamba kupita pansi molingana ndi silinda yogwira ntchito. Pamene mawilo a galimoto akusunthira pafupi ndi thupi la galimotoyo, chotsitsa chodzidzimutsa chimapanikizidwa, choncho pisitoni imasunthira pansi. Kuchuluka kwa chipinda chogwirira ntchito kumachepa, ndipo kupanikizika kwa mafuta m'chipinda chocheperako kumawonjezeka, kotero kuti valve yothamanga imatseguka ndipo mafuta amalowa m'chipinda chapamwamba chogwirira ntchito. Chifukwa ndodo ya pisitoni idatenga malo mchipinda cham'mwamba chogwirira ntchito, kuchuluka kwa kuchuluka kwa chipinda chapamwamba chogwirira ntchito kumakhala kocheperako poyerekeza ndi kuchepa kwa chipinda chocheperako, mafuta ena amatsegula mtengo woponderezedwa ndikubwerera m'malo osungiramo mafuta. Makhalidwe onse amathandizira kugunda kwamtima ndikupangitsa mphamvu yotsitsa ya shock absorber. (Onani tsatanetsatane monga chithunzi 3)

Chithunzi 3: Kachitidwe ka kukanika

2. Kubwereranso
Ndodo ya pistoni ya shock absorber imasunthira mmwamba molingana ndi silinda yogwira ntchito. Pamene mawilo a galimoto akuyenda kutali ndi thupi la galimotoyo, chosokoneza chodzidzimutsa chimapangidwanso, motero pisitoni imakwera m'mwamba. Kuthamanga kwa mafuta m'chipinda chapamwamba chogwirira ntchito kumawonjezeka, choncho valve yothamanga imatsekedwa. Valve yobwereranso imakhala yotseguka ndipo mafuta amalowa m'chipinda chocheperako chogwirira ntchito. Chifukwa mbali imodzi ya ndodo ya pisitoni sinagwire ntchito, kuchuluka kwa silinda yogwira ntchito kumawonjezeka, mafuta omwe ali munkhokwe yamafuta amatsegula valavu yolipirira ndikulowa m'chipinda chocheperako. Makhalidwe onse amathandizira kugunda kwamtima ndikupangitsa mphamvu yotsitsa ya shock absorber. (Onani tsatanetsatane monga chithunzi 4)

Chithunzi 4: Njira Yobwereranso

Nthawi zambiri, mphamvu yolimbikitsira isanachitike ya valavu yobwereranso ndi yayikulu kuposa ya valavu yopondereza. Pansi pa kupanikizika komweko, gawo la mtanda la mafuta limayenda mu valve rebound ndi laling'ono kuposa la compression valve. Chifukwa chake mphamvu yochepetsera munjira yobwereranso ndi yayikulu kuposa yapanthawi yoponderezana (zowona, ndizothekanso kuti mphamvu yonyowa pakuponderezana ndi yayikulu kuposa mphamvu yopumira munjira yobwereranso). Mapangidwe awa a shock absorber amatha kukwaniritsa cholinga choyamwa mwachangu.

M'malo mwake, chotsitsa chododometsa ndi chimodzi mwazomwe zimawola mphamvu. Chifukwa chake mfundo yake imachokera pa lamulo losunga mphamvu. Mphamvuyi imachokera ku njira yoyaka mafuta; galimoto yoyendetsedwa ndi injini imagwedezeka mmwamba ndi pansi pamene ikuyenda mumsewu wovuta. Galimoto ikagwedezeka, kasupe wa koyilo imatenga mphamvu yakugwedezeka ndikuisintha kukhala mphamvu yomwe ingatheke. Koma kasupe wa koyilo sangathe kuwononga mphamvu yomwe ingathe, ikadalipo. Zimapangitsa kuti galimotoyo igwedezeke mmwamba ndi pansi nthawi zonse. Chotsitsa chododometsa chimagwira ntchito kuti chiwononge mphamvu ndikuchisintha kukhala mphamvu yotentha; mphamvu yotentha imatengedwa ndi mafuta ndi zigawo zina za kugwedeza kwadzidzidzi, ndikutuluka mumlengalenga pamapeto pake.
