Problems solved by technology

[0003] In order to improve the safety performance of the electric vehicle during driving, the electric wheel hub needs to undergo a pressure test when it leaves the factory. The pressure test includes hardness, wear resistance and anti-collision performance, etc. The existing devices are performing these functions. When testing, it needs to be completed with different instruments, which not only increases the cost of testing, but also reduces the efficiency of the entire measurement

Abstract

The invention discloses an electric vehicle hub pressure-bearing test bench, which comprises a basic module, a hoisting module, a power module, a resistance module and a lifting module. The base module comprises a mounting table, a vertical plate fixedly connected with the mounting table, frame bodies which are symmetrical about the vertical center line of the vertical plate and fixedly connected with the mounting table, an L-shaped supporting table mounted between the two frame bodies and a hub connected with the base module, and a storage opening is formed in the top of the L-shaped supporting table; and two circular cavities are formed in the L-shaped supporting table. According to the test bench, a rotating shaft with a hub is clamped by two clamping plates, then fixation of a sliding plate and the rotating shaft is completed under the condition that a driving gear and a driven gear are ensured to be meshed, then the two clamping plates are opened by a bidirectional electric push rod, the rotating shaft falls between a first limiting plate and a second limiting plate, friction force is generated between the hub and the bottom of an inner cavity of a frame body, and the rotating shaft moves; the resistance module increases the resistance of the rotating shaft to ensure the accuracy of the wear resistance test.

Description

technical field [0001] The invention relates to the technical field of electric wheel hub testing, in particular to an electric wheel hub pressure test bench. Background technique [0002] Electric car, also known as electric drive car. Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Generally speaking, the electric vehicle uses the battery as the energy source. Through the controller, the motor and other components, the electric energy is converted into mechanical energy to move, so as to control the current and change the speed of the vehicle. The electric wheel hub is a drum shaped, A metal part centered on a shaft. Also known as rims, steel rims, wheels, and tire bells. There are many types of hubs according to diameter, width, molding method and material. [0003] In order to improve the safety performance of the electric vehicle during driving, the electric wheel hub needs to undergo a pressure test when it leaves the factory. The ...
