差速器行星齿轮结构优化
|
摘要
汽车差速器是当车辆行驶在不平路面或转弯等情况时,可使两侧车轮以不同角速度旋转同时传递扭矩,从而消除左、右车轮在汽车运动学上的不协调,是汽车传动系中的关键零部件之一,其力矩的分配和各构件的强度直接决定着车辆的转向性能、通过性和可靠性。差速器内一般包含行星齿轮、半轴齿轮,行星齿轮与半轴齿轮相比体积较小,在承受相同载荷的情况下,行星齿轮更易损坏。本文通过优化行星齿轮结构,达到提高行星齿轮可靠性的目的。
When the vehicle is on uneven road or turn,automobile differential can make the wheels rotate in different angular velocity and transmit torque at the same time.It can eliminate the dissonance of left and right wheels in automobile kinematics,one of the crucial part in automobile transmission system.The distribution of the torque and the strength of each component directly determine the vehicle's steering performance, adoption and reliability.The differential contains planetary gear and axle gear and the planetary gear is smaller than the half shaft gear,in the case of the same load, the planetary gear is more vulnerable to damage.By optimizing planetary gear structure, this paper aims to improve the reliability of planetary gear.
