Stall brake assembly for testing performance of electric vehicle tire

Abstract

A stall brake assembly for an electric vehicle tire performance test relates to the technical field of electric vehicles and comprises a brake disc, a brake drum is movably connected to the outer sideof the brake disc, wherein a brake mechanism and a driven mechanism are movably connected to the interior of the brake disc. The stall brake assembly used for the electric vehicle tire performance test is provided; based on the advantages of stall braking, when the rotating speed of the test equipment is stalled, namely, the rotating speed exceeds a specified value, automatic braking can be performed to stop the rotation of the test equipment, so that the problems of abnormal rotating speed and specified test requirement exceeding caused by a stall phenomenon can be prevented, and the problemof experimental data deviation caused by increase of the tire wear degree due to stall is further avoided. The accuracy of experiment and test data is effectively ensured, the authenticity and credibility of the test data are improved, the actual performance of a product can be reflected most truly, the problem of product reinspection caused by deviation of the experiment data is avoided, and theproduction progress is improved to a certain extent.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a stall brake assembly used for performance testing of electric vehicle tires. Background technique [0002] Electric vehicles are divided into electric vehicles and electric bicycles. As people's awareness of energy conservation and environmental protection increases, the proportion of electric vehicles in transportation is also increasing. [0003] For electric bicycles, a series of tests are required before leaving the factory to ensure the performance of this type of product. Among them, the wear resistance test of tires is one of the important test items, which determines the performance of electric bicycles. When carrying out the wear resistance test of tire performance, the commonly used method is to fix the tire on the rotating shaft, rotate it at a certain speed, and observe the wear degree of the tire within a specified time. Due to mechanical or equipment re...

AI Technical Summary

Problems solved by technology

Due to mechanical or equipment reasons, the speed of the shaft may stall during the test, that is, the speed exceeds the specified test requirements. At this time, compared with the experimental data under normal speed test conditions, the wear of the tires will be higher, causing the test The deviation from the test data will affect the control of product performance, and may cause the entire batch of products to be re-tested, seriously affecting the normal progress of production

[0004] In order to solve the above problems, the inventor proposed a stall brake assembly for performance testing of electric vehicle tires, which has the advantages of stall brake and can avoid a series of problems that may be caused by stall
