Abstract

The invention relates to a semiaxis gear dismounting force and press mounting force testing device, comprising a platen and a semiaxis seat, a gear seat, a pull pressure sensor and a cylinder which are all arranged on the platen. The semiaxis seat and the gear seat are arranged on left and right sides, and are both installed in a liner sliding cooperative connection mode; the pull pressure sensor is located on the left side of the semiaxis seat, and has the left end fixed, and the right end connected to the semiaxis seat; the cylinder is located on the right side of the gear seat, the cylinder body located on the right end is fixed, and a piston extending terminal located on the left end is connected to the gear seat; the semiaxis seat is provided with a semiaxis seat hole used for insertion of a semiaxis and restricting the semiaxis from separating from the semiaxis seat towards the right; the gear seat is provided with a gear seat hole used for insertion of a gear and restricting the gear from separating the gear hole of the gear seat towards the left; the axes of the pull pressure sensor, the semiaxis seat, the gear seat hole and the cylinder are parallel and coaxial. The semiaxis gear dismounting force and press mounting force testing device can realize semiaxis gear dismounting force and press mounting force test so as to verify the reasonability of improved designs.

Description

technical field

[0001] The invention relates to a detection device for a transmission of an electric vehicle, in particular to a testing device for dismounting force and press-fitting force of a half-shaft gear of the transmission of an electric vehicle. Background technique

[0002] At present, the test device for the dismounting force of the side gear of the electric vehicle transmission is generally carried out on a hydraulic tensile testing machine, but this method requires special manufacturing of special fixtures, or manual disassembly is complicated, and the equipment that meets the test range is huge, or the accuracy It is difficult to meet the requirements, and the operation and calculation are complicated. Another way is to use pulley blocks and steel wires to hoist the parts to be tested, and measure the disassembly force by adding weights. This method cannot test the press-fitting force.

[0003] At present, electric vehicles are developing rapidly, and there is...
