Kala simbiriirixan Limited - waa maxay dabeecadihiisa?

Faraqa dhibic farsamo of view waxaa loo tixgeliyaa sida qalab in qaybiyaa dhexeeya Xuddunta usheeda dhexe talooyin ah. Waxay ku taalaa ee drive gaari. kala duwan ee gaariga, siday u kala horreeyaan, qaybisay xilligan ka usheeda dhexe aqbasho ama Gudbinta cardan kala dhex martaa giraangiraha semiaxes gaariga si siman.

kala duwan ayaa loo baahan yahay si ay u eryi giraangirihiina in ay isku shaandheyn ugu velocities angular kala duwan. Marka aad baabuurka wheel gudaha maraa arc ka gaaban ka baxsan. Laakiin haddii giraangirihiina way isku shaandheyn xawaare la mid ah, mid ka mid ah waa in lagu daraa in wareeg ah iyadoo warqada. Tani, markeeda, si xun u saameyn gobolka oo ka mid ah taayirada iyo manageability. Sidoo kale duwan wareejinta Xuddunta inay dariiq dhexaad drive si joogto ah.

Haddii gaariga uu leeyahay dariiq dhexaad wadista, faraqa ku yaal waxa on, haddii gaariga yahay oo dhan-wheel drive, ka dibna waxaa jira saddex kala duwan - in oo ulahooda wareejiya kexeeyey oo u dhaxeeya. Haddii dhidibka sayidkiisa gaariga waxaa labanlaabmay, ka dibna on faraqa dariiq dhexaad walba waxa uu ku yaalaa sidoo kale ka mid ah baabuurta afarta wheel. Si kastaba ha ahaatee, mashiinada sida halka drive dhan-wheel si ay u tagaan on daahan a cufan laguma talinayo.

faraqa Limited warqada (ama kala duwan la sare iska caabin gudaha, gaaban DPVS) ka duwan kan caadiga ah ee in velocities angular of dhigay fallaadhihii aqbasho ma eka. Tani waa muhiim marka aad wadid gaari off-road. kala duwan warqada Limited awood ku sii xaaladda marka hal dariiq dhexaad wheel drive ayaa xiriir la lahayn wadada. Xaddididda farqiga u of velocities angular giraangiraha gudbin karaan daqiiqad waxtar leh ilaa ugu yaraan hal giraangiraha waa in xiriir la wadada.

Hadda waxaa jira laba nooc oo kala warqada ku koobnayn, loo isticmaalo in injineernimada baabuurta oo casri ah. Nooca ugu horeeya - kala duwan oo xasaasi ah xagga kala duwanaanta daqiiqado (ama SARS). Nooca labaad - farqiga u xasaasi ah xawaaraha (ku salaysan ee u xigay viscous). Noocani waa nooc ugu caansan maxaa yeelay, waa dayactirka yar hawl badan.

Qorshahaa waxa ka mid ah nooca kala duwan viscous waa ka fudud marka la barbardhigo nooc kale oo kala warqada ku koobnayn. Muuqaalka kala waa in shaqada noocan ah ayaa ugu siman.

kala duwan ayaa lagu rakibi karo on baabuurta kala duwan. Khubarada ogahay, tusaale ahaan, ku koobnayn wha kala duwan warqada. Sidoo kale waxaa jira kala duwan warqada nooc ka mid ah fur kooban. Tusaale ahaan, warqada ku koobnayn kala duwan nooca "Kvayf" (Quaife). Waxaa loogu talagalay in ay baabuurta la drive hor-wheel. kala duwan Tani waxay si buuxda Ogaan Xuddunta ah ee engine ku sari gudaha on barafka ama in ay dhacdo jar on giraangiraha drive uu noqon doono ka badan. Wheel xiriir la wadada isagoo, uu helo Xuddunta oo dheeraad ah, halka wheel la mashquulsanayeen, ayaa laga badiyay xiriir la wadada ama axlebox on baraf. permeability Car noqdo dardargelinta wanaagsan ee xilliga qaboobaha - ugu firfircoon. Intaa waxaa dheer, soo hagaagtay manageability, iyo dareenka reer baydalka xawaaraha.
