An automobile double drive axle test device

Abstract

An automobile double drive axle test device, comprising a supporting device for fixing the middle axle of the automobile to be tested, a rear axle of the automobile to be tested connected with the middle axle of the automobile to be tested, a driving mechanism connected to the input end of the middle axle of the automobile to be tested, and The two output terminals of the middle axle of the vehicle to be tested and the loading mechanism respectively connected to the two output terminals of the rear axle of the vehicle to be tested; An input torque speed sensor is installed on the output shaft; the loading mechanism includes a loading motor, a shaft coupling, a gear box, and a transmission shaft connected in sequence, and an output torque speed sensor is installed on the output shaft of the gear box. The invention can simply test the middle axle and the rear axle in linkage to achieve the purpose of simulating the working conditions of the whole vehicle to evaluate the middle axle and the rear axle assembly, and can simulate the working conditions of the whole vehicle to carry out the differential test of the middle axle and the rear axle. The advantages of simplicity, compact layout and high reliability.

Description

technical field [0001] The invention relates to an automobile double drive axle test device, which is mainly used for simulating the working conditions of the middle axle and the rear axle of the automobile to carry out performance and life tests. Background technique [0002] At present, when conducting the test of the automobile middle axle bench test and the rear axle bench test, the two tests are carried out separately. In the test, the middle axle and the rear axle of the car due to factors such as drive axle transmission efficiency and mechanical design are not considered in the test. The rear axles of the vehicles influence each other. Conventional tests cannot scientifically simulate the working conditions of the whole vehicle to test the middle axle and rear axle in linkage, so the conventional test bench cannot meet the needs of different types of automobile middle axle and rear axle bench tests. At the same time, it is quite difficult to ensure that the middle ax...

Problems solved by technology

[0002] At present, when conducting the test of the automobile middle axle bench test and the rear axle bench test, the two tests are carried out separately. In the test, the middle axle and the rear axle of the car due to factors such as drive axle transmission efficiency and mechanical design are not considered in the test. Rear axles of cars interact with each other

The conventional test cannot scientifically simulate the working conditions of the whole vehicle to test the middle axle and the rear axle in linkage, so the conventional test bench cannot meet the needs of different types of automobile middle axle and rear axle bench tests

At the same time, it is quite difficult to ensure that the middle axle and the rear axle do not have differential speeds at the same time during the linkage test of the middle axle and the rear axle of the car. There is no relevant test bench in China.
