Test bench for testing electric drive axle

Abstract

The invention discloses a test bench for testing an electric drive axle. The test bench comprises a supporting table, the four corners of the lower part of the supporting table are connected with height adjusting screw rods, the outer sides of the height adjusting screw rods are in engaged connection with screw cylinders, the outer sides of the screw cylinders are connected with tooth cylinders, a height driving motor is installed at the position, located among the four height adjusting screw rods, below the supporting table, the output shaft end of the height driving motor is connected with a driving gear, and the driving gear is connected with four tooth cylinders in an engaged mode. Through the arrangement of the height adjusting screw rods, the screw cylinders, the movable driving motor, the height driving motor, the driving gear and a tooth cylinder base, under the mutual cooperation of the structures, the function that the height of the supporting table is convenient to adjust is achieved, and the device is suitable for operators of different heights to operate, high in automation degree and high in stability. The test bench is suitable for testing the electric drive axle.

Description

technical field [0001] The invention belongs to the technical field of test benches, and in particular relates to a test bench for testing electric drive axles. Background technique [0002] The electric drive axle, that is, the drive axle, is composed of the main reducer, the differential, the wheel transmission device and the drive axle housing. After the main reducer reduces the speed and increases the torque, it is distributed to the left and right axle shafts and driving wheels through the differential. Before the electric drive axle is put into use, its performance needs to be tested. During the test, a test bench is required , however, there are still some deficiencies in existing test benches for e-axle testing. [0003] The existing ones have the following problems: 1. The height of the support platform is inconvenient to adjust, and it is not convenient for staff of different heights to operate; 2. It is not convenient to fasten and clamp electric drive axles of d...

AI Technical Summary

Problems solved by technology

[0002]The electric drive axle, that is, the drive axle, is composed of the final reducer, differential, wheel drive and drive axle housing, etc. The power of the motor turns over 90 degrees to change the transmission direction of the force, and the speed is reduced by the final reducer. After increasing the torque, it is distributed to the left and right axle shafts and driving wheels through the differential. Before the electric drive axle is put into use, it is necessary to Its performance is tested. During the test, a test bench is needed. However, there are still some defects in the existing test bench for electric drive axle testing.

[0003]The following problems exist in the existing ones: 1. The height of the support table is not easy to adjust, and it is not convenient for staff of different heights to operate; The driving axle is fastened and clamped, and the scope of application is relatively limited
