摘要： 本项目设计的液力差速器以液力变矩器为基础，由液力传动实现差速器自动差速与防滑，保证汽车在各工 况正常行驶。结构上将主减速器从动锥齿轮盘部分为泵轮，传统差速器两侧半轴齿轮部分为涡轮，由中间泵轮带动 两侧涡轮使车轮转动，并取消车轮的刚性连接，运动过程独立。实现自动差速与防滑，提高主减速器和差速器的使 用寿命，实现无级变速。根据整车动力传动和性能要求，计算得到液力差速器的比转速、循环流量、循环圆直径等 参数。

Abstract: The hydraulic differential designed in this project is based on the hydraulic torque converter, and it is planned to realize the differential automatic differential and anti-skid by hydraulic transmission, so as to ensure the normal driving of the vehicle in various working conditions. In the structure, the driven bevel gear plate of the main reducer is the pump wheel, and the half shaft gears on both sides of the traditional differential are the turbines. The middle pump wheel drives the turbines on both sides to make the wheels rotate, and cancels the rigid connection of the wheels, so the movement process is independent. Realize automatic differential and anti-skid, improve the service life of main reducer and differential, and realize stepless speed change. According to the vehicle power transmission and performance requirements, the specific speed, circulation flow, circulation circle diameter and other parameters of the hydraulic differential are calculated.
