AI Technical Summary

Technical Problem

In existing wet drive axles of loaders, the lubricating oil in the wet brake assembly cannot flow well with the oil in other parts of the drive axle, resulting in abnormally high lubricating oil temperature, causing piston seal aging and friction plate wear.

Method used

An oil propulsion device consisting of a sleeve, helical blades, and spline sleeve is installed on the half-shaft and assembled to the outer circle of the half-shaft by fixing screws to achieve good flow of lubricating oil, increase heat dissipation area, and absorb heat from the wet brake.

Benefits of technology

It improves the reliability and service life of the drive axle, solves the problem of excessively high oil temperature in wet brakes caused by the inability of lubricating oil to flow, and extends the service life of piston seals and friction plates.

Abstract

本实用新型公开了一种装载机湿式驱动桥半轴总成结构,包括半轴、套管、螺旋叶片、花键套和末端带凸台的固定螺钉;套管与半轴采用孔对轴间隙配合,套管外圆焊接螺旋叶片,套管右端与花键套用焊接连接;花键套内孔设花键,并在圆周方向设螺纹通孔,使套管、螺旋叶片和花键套组成油液推进器;花键套的内花键和半轴的右侧外花键连接,该右侧外花键外圆设半轴固定环槽,使油液推进器的轴向位置通过固定螺钉的凸台嵌入半轴固定环槽上。本实用新型可使湿式制动器总成位置润滑油与驱动桥其他位置的油形成良好流动,解决了现有湿式制动器总成位置的润滑油无法与驱动桥其他位置的油相互流动引起湿式制动器油温过高造成活塞密封件老化和摩擦片磨损的问题。
