托森差速器建模及运动仿真

3D Modeling and Kinematics Simulation of Torsen Differential

汽车差速器是能够使左、右两个驱动轮实现以不同转速转动的一种机构。主要由左右半轴齿轮、行星齿轮(至少一组)及齿轮架组成。功用是当汽车转弯行驶或在不平路面上行驶时,使左右车轮以不同转速滚动,即保证两侧驱动车轮作纯滚动运动。托森(Torsen)差速器就是众多差速器中十分著名的一种。文章将针对托森差速器,在3D建模软件Solid Works中建立装配模型,并对其进行运动学仿真,通过对运动学仿真结果分析,得到其运动特性。

Automotive differential is a mechanism which allows the left and right driving wheels rotate at different speeds. It mainly consists of left and right half axle gears, planetary gears (a pair at least) and the gear frame. Its function is to allow the left and right wheels rolling at different speeds when the car is steering or driving on uneven roads, which ensure the pure rolling motion of the driving wheels on both sides. Torsen differential is one of the most famous differentials. In this paper, the assembly model of Torson differential is built in Solid Works, which is a 3D modeling software, and its kinematics simulation is carried out. Through the analysis of kinematics simulation results, the kinematics characteristics of Torson differential are obtained.
