Problems solved by technology

[0002] At present, automobile disc brake pads often encounter brake noise during use, especially the problem of low-speed brake noise. However, the noise detection test device in the prior art is not only complicated in structure, high in cost, and high in use cost, but also in When detecting the noise problem of disc brake pads, the test results are often quite different from the actual working conditions, which cannot provide reliable test data support for the production of automobile disc brake pads, and cannot realize low-speed noise detection of disc brake pads. Accurate testing and quality control, causing unnecessary economic losses to brake pad manufacturers

Abstract

The invention discloses a brake disc noise detection test apparatus, and relates to the technical field of automobile noise detection. The brake disc noise detection test apparatus includes a motor, a speed reducer, a brake disc and a brake braking apparatus, wherein the motor drives the speed reducer to simulate automobile low speed running; by means of setting of an inertia wheel, the test data can be more close to the practical working condition; by means of random braking of the brake braking apparatus, low speed braking of the brake disc is simulated really, so as to directly test whether braking noise is generated when the brake disc is braked, so that noise production during the low speed braking process of the brake disc can be based on the evidence; and at the same time, a temperature sensor is arranged on the brake disc, and can test whether the brake disc generates noise or test the generated braking noise state when different temperatures are generated because of braking, thus providing test data support for brake disc production; and the whole brake disc noise detection test apparatus has the advantages of being simple in structure, being short in production period, being convenient to use, and being able to directly control the quality of the produced brake disc.
