Servicing of Differential System
Differential is an important mechanical system of four wheeler vehicle. It plays important role for smooth driving of vehicle specially on curved path while vehicles is taking turn on curved path with respect to inner wheels outer wheel should have to travel comparatively more distance within same interval of time. To take smooth turn on curved path without skidding specific characteristic system is used. This could be achieved by using differential which vary speed of two wheels. With respect to inner wheel out wheel should have more speed and the outer wheel travel more distance than inner wheel.
Differential is used in rear axle of rear wheel drive vehicles. Differential is also used in trans axles in front engine front wheel drive vehicles. In four wheeler four wheel drive vehicles have differential is at both front and rear axle. In some four wheel drive vehicle have a third differential in transfer case. But in most of the vehicle are front engine rear wheel drive. In this vehicle differential is attached between the real axle of two rear wheels. This drive of vehicle power produced in engine is transmitted through transmission system to differential.
In this drive two solid shaft part is attached one end is attached with rear wheel and other and with differential. Both shafts one end is attached with differential and other part with wheels.
Inner end of each axle is a small bevel gear called differential side gear when two bevel gears are put together their teeth mesh driving and driven shaft are attached at 90° angle.
