Example Embodiment

[0011] From figure 1 , figure 2 It can be seen that: an automobile drive axle wheel-side planetary wheel shaft with oil passages, including a shaft body 12, is characterized in that: the left end section and the right end section of the long cylindrical shaft body 12 are both stepped cylindrical sections, so From left to right, the shaft body 12 is a left step cylindrical section 6, a shaft body section 3, and a right step cylindrical section 5, and the diameters of the left and right step cylindrical sections 6, 5 are all smaller than the diameter of the shaft section 3. Grinding wheel overtravel grooves 4 are set at the junctions of the step cylindrical sections 6, 5 and the shaft section 3 to facilitate grinding the outer peripheral surfaces of the left and right step cylindrical sections 6, 5 and the shaft section 3. In addition, in the shaft The body 12 is provided with an axial central through hole 1, and in the middle of the shaft section 3 is provided a radial through ...

Abstract

The invention discloses an automobile drive axle wheel-side planet axle with an oil duct, belonging to automobile driving devices. The automobile drive axle wheel-side planet axle with the oil duct is characterized in that a left end section and a right end section of a long-cylindrical shaft body are stepped cylindrical sections so that the shaft body is sequentially provided with a left stepped cylindrical section, a shaft body section and a right stepped cylindrical section from left to right, and the diameters of the left stepped cylindrical section and the right stepped cylindrical section are smaller than the diameter of the shaft body section; junctures of the left, the right stepped cylindrical sections and the shaft body section are respectively provided with a grinding wheel undercut; in addition, the shaft body is provided with an axial central through hole, the middle part of the shaft body section is provided with a radial through hole communicated with the axial central through hole, and the axial central through hole and the radial through hole form a lubricating oil duct; therefore, lubricating oil can circulate, and the lubricating oil in a wheel-side shell can flow into a needle roller along the lubricating oil duct in the planet axle; and the lubricating effect is good.

Description

technical field [0001] The invention belongs to an automobile driving device, in particular to an automobile drive axle wheel side planetary wheel shaft. technical background [0002] The wheel-side planetary shaft of the existing automobile wheel-side deceleration drive axle is often a solid circular shaft. After the planetary wheel is installed, it is difficult for lubricating oil to enter the needle roller (or needle bearing) between the planetary wheel shaft and the planetary wheel. It leads to poor lubrication, accelerates the wear of the planetary shaft and the planetary gear, and affects the service life of the drive axle. Contents of the invention [0003] The object of the present invention is to propose a wheel-side planetary wheel shaft of an automobile drive axle with an oil passage, so that lubricating oil can easily enter the needle roller (or needle bearing) between the planetary wheel shaft and the planetary wheel, thereby improving lubrication and extendin...
