Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle braking, and particularly relates to a steel back of a brake pad with high strength and rapid cooling. Background Art

[0002] The brake pad is an important safety component in the vehicle braking system, and a brake pad with excellent performance is of great significance for improving the braking effect of the vehicle.

[0003] At present, the heat dissipation problem and the overall strength problem of the brake pad are important obstacles affecting the service life and braking performance of the brake pad. The service life of most brake pads is only 30,000 - 50,000 kilometers, which greatly increases the use cost. Moreover, due to the disadvantages of poor heat resistance and slow heat dissipation of the brake pad, the brake pad will remain at a high temperature after continuous braking of the vehicle, resulting in softening of the material and reduction of the friction coefficient. At the same time, due to the structural design defects of most brake pads, during high-intensity emergency braking, the friction material and the steel back of the brake pad will fall off due to the strong impact force, and then there is a risk of brake failure, endangering the life safety of the driver. Summary of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides a steel back of a brake pad with high strength and rapid cooling. The structure of the steel back is scientifically and reasonably designed, and has a high connection strength while ensuring the heat dissipation effect, which not only improves the service life of the steel back, but also ensures the life safety of the driver.

[0007] Preferably, the main body heat dissipation group is located in the middle of the steel back main body, and includes five ventilation holes I, ventilation holes III symmetrically arranged on both sides of the central ventilation hole I, and ventilation grooves connecting the ventilation holes I and the ventilation holes III.

[0008] Further preferably, the diameter of the ventilation hole I is 15 mm, and the diameter of the ventilation hole III is 5 mm.

[0021] In order to enable those skilled in the art to better understand the utility model, the technical solutions of the utility model will be further described below with reference to the drawings and embodiments.

[0022] Embodiment 1: A steel back for brake pads with high strength and rapid cooling, the structure is referred to Figures 1-4As shown in the figure, it includes a steel back body 1. According to the distribution state of the friction material layer of the brake pad and the heat dissipation requirements, a main body heat dissipation group 11 is specifically set on the steel back body 1. Auxiliary heat dissipation groups 12 are symmetrically arranged on both sides of the main body heat dissipation group 11; a first fixing groove 3, a second fixing groove 4, and a third fixing groove 5 are arranged around the steel back body 1; mounting grooves 6 are arranged on both sides of the steel back body 1, and clamping grooves 2 are symmetrically arranged.

[0023] Among them, the main body heat dissipation group 11 includes five first ventilation holes 7, third ventilation holes 9 symmetrically on both sides of the central ventilation hole, and ventilation grooves 10 connecting the first ventilation holes 7 and the third ventilation holes 9; the main body heat dissipation group 11 ensures that approximately 70% of the heat in the brake pad is dissipated according to the distribution of the friction material layer in the brake pad (the middle part of the brake pad is the main friction area, and the friction material in the middle part accounts for about 70% of the total friction material layer).

[0024] The auxiliary heat dissipation group 12 includes a second ventilation hole 8, a third ventilation hole 9, and a ventilation groove 10 connecting these two ventilation holes.

[0025] The auxiliary heat dissipation groups 12 are symmetrically arranged on both sides of the main body heat dissipation group 11. The auxiliary heat dissipation group 12 ensures that the remaining approximately 30% of the heat in the brake pad is dissipated according to the distribution of the friction material layer in the brake pad (the two sides of the brake pad are auxiliary friction areas, and a grooving structure will be designed on both sides of the friction material layer to reduce noise and vibration, so the friction material on both sides accounts for a relatively small proportion, about 30% of the total friction material).

[0026] In this embodiment, the ventilation grooves 10 connect the ventilation holes, which can make the heat dissipation efficiency of the brake pad reach the highest.

[0027] While the main body heat dissipation group and the auxiliary heat dissipation group achieve the optimal heat dissipation effect, the increased void area enhances the connection strength between the friction material of the brake pad and the steel back, avoiding the risk of the friction material falling off.

[0028] The first fixing groove 3, the second fixing groove 4, and the third fixing groove 5 are respectively arranged around the steel back body 1, which are used to fix and cooperate the brake pad with the caliper to prevent the brake pad from shaking and further improve the installation strength of the brake pad.

[0029] The mounting grooves 6 are symmetrically arranged on both sides of the steel back body 1, which are also used to fix and cooperate the brake pad with the caliper, further strengthening the installation strength of the brake pad.

[0030] The clamping grooves 2 are symmetrically arranged on both sides of the center of the steel back body 1, which are used to install wear sensors to detect the wear amount of the brake pad and feedback data, ensuring the effective working duration of the brake pad and avoiding the risk of brake failure caused by material deficiency of the brake pad.

[0031] Embodiment 2: A steel backplate for a brake pad with high strength and rapid cooling, having the same structure as that described in Embodiment 1, except that the diameter of Ventilation Hole 1 is 15 mm, the diameter of Ventilation Hole 2 is 10 mm, and the diameter of Ventilation Hole 3 is 5 mm. This design can ensure the heat dissipation effect on the one hand and guarantee the overall strength of the steel backplate on the other hand.
