摘　　要：粘性联轴器这一新装置以其独有的特性在四轮驱动汽车上得到广泛应用。粘性联轴器一经确定结构，即可通过转速差自动调节传递转矩的特性，驱动一个桥，使两轮驱动汽车轻易变为四轮驱动汽车。从汽车的行驶工况出发，采用轮胎纯纵滑理论模型，分析了四轮驱动汽车采用粘性联轴器的可能性。介绍了采用粘性联轴器连接的四轮驱动形式和工作原理，阐述了汽车速度、轮胎滑移率对粘性联轴器转速差的影响。The cohesive shaft coupler,a new device with its unique character is widely applied in 4 wheel drive motor vehicles.Once the structure of cohesive shaft coupler is determined,the characteristic of rotating torque can be adjusted and transferred automatically by rotation speed difference to drive one axle,that makes a tow wheel drive motor vehicle change to a four wheel drive motor vehicle easily.In view of running condition of motor vehicle,the possibility to use the cohesive shaft coupler in 4WD motor vehicles is analyzed by using pure longitudinal sliding theory model of tyre.The type and working principle of 4WD which connected by cohesive shaft coupler are introduced,the effect of motor vehicle speed and tyre sliding rate on rotation difference of cohesive shaft coupler are described.
