Automobile double-drive-axle tester

Abstract

An automobile double-drive-axle tester comprises a support device, a driving mechanism and a loading mechanism; the support device is used to fix a to-be-tested middle axle of an automobile and a to-be-tested rear axle, connected to the to-be-tested middle axle of the automobile; the driving mechanism is connected with the input end of the to-be-tested middle axle, and comprises a driving motor, an input shaft coupling, an input reduction box and an input transmission shaft connected successively, and an output shaft of the input reduction box is provided with an input torque and rotation speed sensor; and the loading mechanism is connected with two output ends of the to-be-tested middle axle and two output ends of the to-be-tested rear axle, and comprises a a loading motor, a shaft coupling, a gear case and a transmission shaft connected successively, and an output shaft of the gear case is provided with an output torque and rotation speed sensor. The middle and rear axles are tested in a lined way simply, the middle and rear axle assembly can be examined by simulating the whole automobile condition, the speed difference between the middle and rear axles can be tested by simulating the whole automobile condition, and the tester also has advantages of simple structure, 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.
