Transfer Case: Description and Operation

REPLACEMENT OF TRANSFER CASE OIL
SYSTEM DESCRIPTION
1. The transfer case is a full-time four-wheel drive system developed for stable driving in the worst conditions. It improves not only driving safety on a normal road but also the performance of the vehicle in a slippery road by distributing the power to both, front and rear wheels.
2. A driver may not control front or rear wheel drive directly like a four-wheel drive vehicle.
3. When the front or rear wheels slip, the viscous generates the effect of differential limitation made by viscosity torque of silicon oil inside the viscous coupling, caused by relative revolution difference among interior plates.
4. This system secures optimum drive performance and vehicle safety according to a road by transmitting viscous torque to the side there is a little slippage between front wheels and rear wheels.
5. Rear wheel power set by the above system is transmitted to the rear wheel through the hypoid gear.
