汽车转向下轴与转向上轴的联接结构

Motor steering lower shaft and steering upper shaft connecting structure

Abstract

本发明公开了一种汽车转向下轴与转向上轴的联接结构,包括与转向上轴键连接的上万向节叉、与上端部带定位销的转向下轴焊接的联轴片、橡胶盘、螺栓、中万向节叉和万向十字轴,所述联轴片与橡胶盘通过铆钉铆接,联轴片上开设有方便螺栓装配的工艺孔,所述螺栓的杆部焊接有与橡胶盘下表面配合的下垫圈,橡胶盘通过螺栓、下垫圈、位于橡胶盘与中万向节叉之间的上垫圈以及弹性垫圈、锁紧螺母的配合与中万向节叉连接,中万向节叉通过万向十字轴与上万向节叉连接;所述工艺孔为开设在联轴片边缘的弧形工艺缺口,所述下垫圈的直径与所述弧形工艺缺口的直径之差大于0小于等于3mm。其能防止螺栓松动后从橡胶盘中脱出、掉落,避免造成扭矩传递失效。
The invention discloses a motor steering lower shaft and steering upper shaft connecting structure which comprises an upper universal joint fork in key connection with a steering upper shaft, a shaft coupling sheet welded with a steering lower shaft, a rubber disc, a bolt, a middle universal joint fork and a universal joint pin. The upper end of the steering lower shaft is provided with a locating pin, the shaft coupling sheet is riveted with the rubber disc through a rivet, a process hole bringing convenience to bolt assembling is formed in the shaft coupling sheet, a lower gasket matched with the lower surface of the rubber disc is welded to the rod portion of the bolt, the rubber disc is connected with the middle universal joint fork through cooperation of the bolt, the lower gasket, an upper gasket located between the rubber disc and the middle universal joint fork, an elastic gasket and a locking nut, and the middle universal joint fork is connected with the upper universal joint fork through the universal joint pin. The process hole is an arc-shaped process notch formed in the edge of the shaft coupling sheet, and the difference of the diameter of the lower gasket and the diameter of the arc-shaped process notch is larger than zero and smaller than or equal to 3 mm. According to the motor steering lower shaft and steering upper shaft connecting structure, the bolt can be prevented from taking off and falling from the rubber disc after bolt looseness, and torque transmission failures are avoided.
