technical field [0001] The invention relates to the technical field of automobile braking, in particular to a friction plate and an integrated brake caliper using the friction plate. Background technique [0002] The vehicle needs to perform braking operation during the running process, and the vehicle needs to perform parking operation during the stopping process. Therefore, the research on the braking system of the vehicle has become the focus of current research. [0003] In the braking system of a car, the brake pad is the most critical safety part, and the brake pad plays a decisive role in the braking effect. In the production process of the whole vehicle, the friction coefficient of the brake friction material of the integrated brake caliper needs to be stable to ensure that the whole vehicle can be rolled off the assembly line smoothly. At the same time, the brake pads also need to ensure the stability of the brakes after the new car is delivered. An integrated brak...

Problems solved by technology

[0004] The integrated brake caliper achieves braking through the friction plate acting on the brake disc. Although from the perspective of long-term use, the performance of the friction plate can generally be in a stable state, and the friction coefficient is between 0.34 and 0.5. The friction coefficient generated by the interaction between the friction plate and the brake disc is not considered in the process of car production and new car use, such as anti-rust oil on the brake disc, floating rust, uneven surface, brake friction process, friction The uneven surface of the disc will lead to the low friction coefficient of the new friction disc. According to research, the friction coefficient in this case generally fluctuates from 0.19 to 0.34, which will lead to unstable parking function of the hand brake during vehicle production and new vehicle use, and even When the friction coefficient is at the level of 0.19, it is very likely to cause a vehicle parking accident

[0005] To sum up, the friction plate of the current integrated brake caliper has the problem of low friction coefficient and instability during the production of the whole vehicle and the use of the new vehicle, which may easily cause braking safety accidents
