摘　　要：限滑差速器是一种通过优化差速器两半轴齿轮扭矩分配达到提高车辆在特定路面条件下通过性能的差速器。文章介绍了一种在普通对称行星齿轮差速器的差速器壳和半轴之间布置弹簧摩擦装置的准限滑差速器机械结构。通过建立这种差速器的力学模型,给出了其锁紧系数特性曲线以及弹簧摩擦装置的设计、计算方法。Limited slip differential is used to promote vehicle trafficability on specific road conditions,this is usuallyachieved by torque re-distribution between two bevel side gears.A kind of Quasi limited slip differential which has a specialfriction mechanism between differential housing and side shaft is introduced in this paper.The characteristic curve of lockingcoefficient and design/calculation method are pointed out by mechanical modeling of the differential.
