摘　　要：提出了一种三周节变传动比限滑差速器。分析了工作原理,提出了齿轮采用非渐开线齿形并沿齿面节线分段设计的方法,对分别装有三周节变传动比差速器的车辆与装有普通差速器的车辆进行了性能对比试验。试验数据表明,三周节变传动比限滑差速器具有增大车辆牵引力和缩短制动距离的作用。A type of three-pitch fluctuating gear ratio limited-slip differential was presented for the first time, the working principles of it were analyzed, the tooth profile design method of using noninvolute tooth profile and separated tooth profile design along the pitch line was introduced, performance comparison between vehicles equipped with three-pitch fluctuating gear ratio limitedslip differential and common open differential has been finished. The data from experiments proved that three-pitch fluctuating gear ratio limited-slip differential could increase the traction of a vehicle, improve its acceleration performance, decrease braking distance and limit sideslip.
