New energy decelerator impact endurance test system and method

Abstract

The invention discloses a new energy reducer impact endurance test system and method. In the test system, a driving motor is connected with an input shaft of a gearbox; an output shaft of the gearbox is connected with an input shaft of a new energy reducer to be tested through a coupler, a torque and rotating speed sensor I and a connecting disc I; the outputs of the two sides of the new energy reducer to be tested are sequentially connected with a half shaft, a connecting disc, a torque rotating speed sensor II, a coupler, a shaft on a bearing seat and a brake device; the output ends of the brake device and all torque and rotating speed sensors are connected with a computer through a data acquisition unit; the computer is connected with the driving motor through a motor controller so as to control the driving motor to work in a needed state, and brake impact is simulated through the brake device. According to the invention, different test working conditions of an impact endurance test of the new energy speed reducer can be flexibly and conveniently simulated, so that impact endurance test data under different working conditions can be rapidly and accurately obtained with low cost.

Description

technical field [0001] The invention relates to a new energy reducer performance test system in an automobile power system. More specifically, the invention relates to a new energy reducer impact durability test system and method, belonging to the technical field of automobile testing. Background technique [0002] With the development of new energy vehicles, new energy reducers have been widely used in new energy vehicles because of their simple structure, low cost, and high transmission efficiency. As an important part of the vehicle transmission system, the new energy reducer can be composed of single-stage or two-stage gear transmission, both of which are integrated with a differential. The reducer can reduce the speed and increase the torque by changing the transmission ratio of the whole vehicle, so as to improve the dynamic performance of the vehicle. The integrated differential can differentially speed the wheels to improve the driving performance and handling perfo...

Problems solved by technology

[0003] At present, the whole vehicle test is the only method for the impact durability test of new energy reducers. This method has disadvantages such as long vehicle preparation time, long test cycle, high cost, and poor consistency of experimental conditions.

Therefore, how to test the impact durability of new energy reducers on the bench is expected to become a new way to solve the shortage of vehicle tests. However, there are no relevant reports at home and abroad.
