The invention relates to an automobile rear axle shaft and half shaft bearing maintenance device and an automobile rear axle shaft and half shaft bearing maintenance method. The automobile rear axle shaft and half shaft bearing maintenance device comprises a maintenance vehicle, and further comprises a half shaft maintenance dismounting mechanism and a half shaft bearing maintenance dismounting mechanism which are arranged on the maintenance vehicle, wherein the half shaft maintenance dismounting mechanism comprises a sliding shaft placed on the maintenance vehicle, a half shaft connection flange arranged at one end of the sliding shaft and used for connecting an automobile rear axle hub and a sliding hammer body slidably sleeving the sliding shaft and corresponding to the half shaft connection flange, and the half shaft bearing maintenance dismounting mechanism comprises a hydraulic oil cylinder structure connected onto the maintenance vehicle, a half shaft connection tube connected with the hydraulic oil cylinder structure and a bearing connection structure arranged on the end part of the half shaft connection tube. The automobile rear axle shaft and half shaft bearing maintenance device aims at solving the problems that a half shaft is difficult to maintain and dismount and high in maintenance cost in the prior art.
Description
technical field [0001] The invention relates to the technical field of vehicle maintenance, in particular to a maintenance device and method for an automobile rear axle half shaft and half shaft bearings. Background technique [0002] The half shaft (Driver Shaft) of a rear-wheel drive car is also called a drive shaft, which is a solid shaft or hollow shaft that connects the differential with the drive wheel and transmits power. The half shaft gear is connected, and the outer end is connected with the driving wheel hub) when repairing, generally all need to carry out heavy disassembly and assembly operations. Because the thick end of the rear axle sleeve is heat-sealed in the rear axle housing when it leaves the factory, it is very difficult to disassemble. It is often knocked out by hammering with a sleeve rod or a sharp drill. The sleeve is broken; and the disassembly of the half shaft bearing is even more difficult, because the interference fit between the rear axle half...
