An automotive electric vacuum pump test system

Abstract

The invention provides an automobile electric vacuum pump test system. The automatic electric vacuum pump test system comprises a pedal force loading system, a pedal, a vacuum booster, a braking main cylinder, a vacuum air storage tank, an electric vacuum pump, a vacuum pump fixing device, a load-sensing proportion valve, a left front wheel cylinder, a right front wheel cylinder, a left rear wheel cylinder, a right rear wheel cylinder and the like, wherein the pedal force loading system is used for exerting loading forces with different torques onto the pedal; and the vacuum pump fixing device is used for fixing electric vacuum pumps in different shapes and with different specifications and sizes onto a rack which is used for test. The electric vacuum pump is placed in the automobile electric vacuum pump test system to be measured, so that the electric vacuum pump is approximate to a service status to the utmost extent, and meanwhile, various index data during test can be output; as the fixing device which can be matched with various electric vacuum pumps is adopted, the electric vacuum pump can be mounted and dismounted conveniently and quickly, and accordingly, the troublesome step of replacing the fixing device during test on different electric vacuum pumps is omitted; the efficiency within unit time is higher; and manpower and material resources in the test process are greatly saved.

Description

technical field [0001] The invention belongs to testing equipment for automobile braking systems, relates to a testing system for automobile electric vacuum pumps, and more specifically belongs to a convenient testing system based on collected data, which is suitable for testing different types of vacuum pumps Background technique [0002] The development of new energy vehicles has made the use of electric vacuum pumps for vehicles more and more widely, and the performance test of electric vacuum pumps has also emerged. The supporting device of the vacuum pump needs to be replaced frequently, which is a waste of time and materials, resulting in a waste of manpower and material resources. At the same time, in the test process, the vacuum pump was not put into the electric vehicle braking system for measurement, and the performance of the vacuum pump was directly tested, ignoring the influence of the braking system on the vacuum pump. Manual loading is used in the pedal loadi...

AI Technical Summary

Problems solved by technology

[0003] The present invention provides a test system for an electric vacuum pump for automobiles in order to overcome the problems of being unable to apply different moment loading forces to the pedals and the cumbersome process of matching and fixing different electric vacuum pumps existing in the existing automobile electric vacuum pump test system
