The invention discloses an on-line detection device and method for thickness of a bullet train brake friction body. The device comprises a T-shaped steel plate, a first detection surface, a second detection surface and a detection reference surface, wherein the first detection surface, the second detection surface and the detection reference surface are arranged on the T-shaped steel plate, the height from the second detection surface to the detection reference surface is H1, the height from the first detection surface to the detection reference surface is H2, and H1 is larger than H2. Compared with the prior art, the device has the positive effects that the friction body size which is important to monitor and is worn to limit is set to be general and stop end size, the size of a general and stop end is sub-divided according to a level needed to be importantly monitored, and the monitoring size level range is expanded; and by the device, the brake friction body which is needed to be importantly monitored or is worn to limit can be conveniently, efficiently and accurately detected in an on-line way.
Description
technical field [0001] The invention relates to an on-line detection device and method for the thickness of a brake pad friction body of a motor vehicle. Background technique [0002] As the core component of the train braking system, brake pads are responsible for the stability and safety of train braking. Among them, the friction body is the key material for the friction and wear of the brake pads, which will produce a certain amount of wear during each braking process. When the thickness of the friction body is reduced to a certain extent, the brake pads will fail, affecting the braking performance and Safe to run. The EMU trains will undergo daily first-level repairs every 2 days. During the repair process, the appearance of the brake pads and the remaining thickness of the friction body will be checked, and the brake pads whose thickness reaches the limit will be replaced. Due to the short primary repair time and the large number of brake pads that need to be inspecte...
