[0016] Figure 2 It is a schematic diagram of the explosion structure of the utility model. DETAILED DESCRIPTION
[0017] The present invention will be further described in detail below in conjunction with specific embodiments and drawings.
[0018] A kind of Figure 1-2 The brake pad wear detection device shown includes a first brake pad fixing seat 1, a second brake pad fixing seat 2, a resistance test contact 3, a slide rail fixing seat 4, and a fixing bolt 5, wherein the first brake pad fixing seat 1 is arranged on the left brake pad mounting plate 6, and the first brake pad fixing seat 1 has two mounting ears, and the mounting ears have connecting holes for being sleeved on the brake pad moving guide column. The second brake pad fixing seat 2 is arranged on the right brake pad mounting plate 7, and the second brake pad fixing seat 2 has mounting ears installed on both sides of the right brake pad mounting plate 7, and the mounting ears have connecting holes, and the installation method is the same as that of the first brake pad fixing seat 1.
[0019] The resistance test contact 3 is fixed on the first brake pad fixing seat 1, and the second brake pad fixing seat 2 is provided with a resistance rod 8 that is in sliding contact with the resistance test contact 3. The first brake pad fixing seat 1 has a transverse through hole, and an embedding groove 9 is provided at one end of the transverse through hole, and the resistance test contact 3 is embedded in the embedding groove 9. The resistance test contact 3 has a circular ring portion 31 that is coaxially arranged with the transverse through hole. The front end of the resistance rod 8 is slidably fitted in the transverse through hole. The resistance test contact 3 and the resistance rod 8 are connected to the vehicle ECU 10 through a circuit, and the brake pad thickness value is displayed on the instrument in an intuitive graphical form.
[0020] When the brake pad is worn during use, the first brake pad holder 1 and the second brake pad holder 2 approach each other, the resistance rod 8 carried by the second brake pad holder 2 is inserted into the first brake pad holder 1, and the resistance that can be received by the resistance test contact 3 changes, and the resistance change signal is transmitted to the ECU, and the ECU calculates the wear degree of the brake pad according to the received signal, and converts the information into a digital signal. Finally, the digital signal is sent to the display screen on the motorcycle instrument, and the wear condition of the brake pad is displayed through a specific icon or numerical value. The second brake pad holder 2 is made of conductive material, and its cylindrical section is made of resistive material. When the brake pad is worn, the resistance rod carried by the second brake pad holder 2 is inserted into the first brake pad holder 1, and the resistance that can be received by the resistance test contact becomes smaller. By measuring the change of the resistance value, the wear degree of the brake pad can be accurately judged.
