POWER TRANSMISSION DEVICE FOR A FOUR-WHEEL DRIVE VEHICLE |
摘要 |
A power transmission system for a four-wheel drive vehicle, comprising an engine for directly driving a primary driven axle, and a torque transmission device for transmitting drive torque from the primary driven axle to a secondary driven axle as required, according to a difference in the rotational speed between the front and rear axles, and the torque transmitted between the front and rear axles is reduced for a given difference in the rotational speed between the front and rear axles as a vehicle speed is increased. Thereby, the unnecessary burden of load on the rear axle members is reduced. Preferably, the torque transmission device comprises a structure for limiting the upper limit of the torque which can be transmitted to the secondary driven axle.
