Description

Technical Field

[0001] The utility model relates to the technical field of automobile brakes, in particular to a composite automobile brake pad structure. Background Art

[0002] Brake pads are a safety part used for automobile braking. The quality of automobile brake pads determines the safety of the braking system. Traditional brake pads are usually composed of a steel backing plate and a friction block. The friction block rubs against the brake disc on the car's wheel to achieve the purpose of deceleration and braking. However, the friction block will generate a higher temperature during the continuous friction with the brake disc, and due to the poor heat dissipation effect of the brake pad, the high temperature generated will continue to accumulate on the brake pad. When the temperature is too high, the steel components in the brake pad will bend and deform, thereby reducing the safety and stability during braking, especially during high-speed driving, which is very likely to cause safety accidents.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] like Figure 1-4As shown, a composite automobile brake pad structure comprises:

[0025] Back panel 1;

[0026] A heat insulation board 2 fixedly mounted on the back board 1;

[0027] A friction block 4 is slidably arranged on the side wall of the heat insulation board 2, and the side wall of the friction block 4 is provided with symmetrically arranged inclined grooves 5;

[0028] A grinding block 6 slidably disposed in the chute 5;

[0029] The connecting assembly at least comprises an elastic plate 3 fixedly mounted on the side wall of the heat insulation plate 2 and fixedly connected to the grinding block 6.

[0030] Specifically, the back plate 1 provides thrust to the heat insulation plate 2, so that the heat insulation plate 2 pushes the friction block 4 to abut against the brake disc for friction, and the inclined groove 5 opened on the side wall of the friction block 4 reduces the contact area between the friction block 4 and the brake disc, so that the friction block 4 provides a deceleration effect to the brake disc while reducing the high temperature generated during friction, thereby avoiding deformation of the brake pad caused by excessive temperature during braking, and the heat insulation plate 2 blocks the heat to avoid heat accumulation on the back plate 1 and deformation of the back plate 1. When the car needs emergency braking, the thrust of the back plate 1 is increased by driving the hydraulic component, so that the elastic member between the heat insulation plate 2 and the friction block 4 is squeezed and deformed, so that the heat insulation plate 2 pushes the grinding block 6 in the inclined groove 5 to be flush with the friction block 4, and the grinding block 6 abuts against the brake disc, so that the friction area of ​​the friction block 4 is increased, thereby quickly braking the brake disc and improving the service life of the brake pad.

[0031] In the above embodiment, when the car needs to slow down, the back plate 1 is pushed by the thrust to drive the friction block 4 to abut against the brake disc of the car, so that the brake disc slows down, and the contact area between the friction block 4 and the brake disc is reduced by the inclined groove 5 opened on the side wall of the friction block 4, so that the contact area is reduced while the car slows down, thereby reducing the heat generated during friction, avoiding heat accumulation and causing deformation of the internal steel components of the friction block 4, and the opened inclined groove 5 can scrape off the dust adhered to the brake disc, thereby improving the braking effect. When the car needs emergency braking, the thrust on the back plate 1 increases, and the elastic plate 3 between the friction block 4 and the heat insulation plate 2 is deformed, so that the heat insulation plate 2 pushes the grinding block 6 to remain flush with the friction block 4, thereby increasing the contact area between the friction block 4 and the brake disc, and improving the braking speed. Not only does it reduce the heat generated by the brake pad during braking, but it also extends the service life of the brake pad, effectively reducing traffic accidents caused by brake pad failure due to high temperature.

[0032] As an embodiment further provided by the present invention, a fixing block 9 is fixedly installed on the side wall of the heat insulation board 2, and a grinding block 6 is fixedly connected to one end of the fixing block 9.

[0033] Specifically, when the heat insulation plate 2 pushes the elastic plate 3 to deform, the distance between the heat insulation plate 2 and the friction block 4 decreases, so that the fixed block 9 installed on the heat insulation plate 2 pushes the grinding block 6 to be flush with the friction block 4, thereby increasing the friction area of ​​the friction block 4.

[0034] As another embodiment further provided by the present invention, the heat insulation board 2 is a ceramic board.

[0035] Specifically, the ceramic heat insulation board 2 can block the heat to a great extent, thereby preventing the heat from diffusing to the back plate 1 and causing the back plate 1 to deform.

[0036] As another embodiment further provided by the present invention, a heat-insulating cavity 11 is provided in the elastic plate 3 .

[0037] Specifically, the heat generated by the friction block 4 during friction is collected and dissipated through the heat-insulating cavity 11 opened in the elastic plate 3 .

[0038] As another embodiment further provided by the present invention, an air inlet hole 7 is opened on the side wall of the heat insulation board 2 , and heat dissipation fins 8 in a linear array are arranged in the air inlet hole 7 , and one end of the heat dissipation fin 8 extends into the heat insulation cavity 11 .

[0039] Specifically, the heat dissipation fins 8 arrayed in the air inlet hole 7 extend into the heat insulating cavity 11, and absorb the heat in the heat insulating cavity 11, so that the heat in the heat insulating cavity 11 enters the heat dissipation fins 8, and the heat absorbed by the heat dissipation fins 8 is dissipated by the airflow flowing in the air inlet hole 7, so that the temperature is taken away by the flowing airflow, thereby improving the cooling effect of the brake pad.

[0040] As another embodiment further provided by the present invention, a linear array of heat exhaust holes 10 is provided at the top of the heat insulation board 2 , and the heat exhaust holes 10 are connected to the air inlet holes 7 .

[0041] Specifically, the air inlet hole 7 and the heat exhaust hole 10 are interconnected, so that the air inlet hole 7 and the heat exhaust hole 10 cooperate with each other to form a heat exhaust air duct. The air flow entering the air inlet hole 7 is heated by the temperature on the heat dissipation fins 8, thereby forming a hot air flow. The hot air flow will accelerate to flow to the high heat exhaust hole 10. At the same time, the air inlet hole 7 will accelerate the intake of fresh cold air, thereby improving the heat dissipation efficiency of the heat dissipation fins 8.

[0042] Working principle: When the car needs to brake, the back plate 1 is driven to provide thrust to the heat insulation plate 2, so that the heat insulation plate 2 pushes the friction block 4 to abut against the brake disc of the car for friction, thereby providing a braking effect for the car, and the contact area between the friction block 4 and the brake disc is reduced by the inclined groove 5 opened on the friction block 4, so that the friction area between the friction block 4 and the brake disc is reduced, which greatly reduces the heat generated when the friction block 4 and the brake disc rub against each other, and the heat is isolated by the isolation plate to prevent the generated heat from diffusing to the back plate 1. When the car needs emergency braking, the back plate 1 is driven to increase the thrust provided to the heat insulation plate 2, so that the heat insulation plate 2 pushes the elastic plate 3 between the friction block 4 to deform, so that the fixed block 9 installed on the heat insulation plate 2 pushes the grinding block 6 in the inclined groove 5 to abut against The elastic plate 3 is provided with a heat dissipation plate 11 and a heat dissipation plate 12, and the heat dissipation plate 12 is provided with a heat dissipation plate 13. The heat dissipation plate 12 is provided with a heat dissipation plate 14, and the heat dissipation plate 12 is provided with a heat dissipation plate 13. The heat dissipation plate 12 is provided with a heat dissipation plate 13, and the heat dissipation plate 12 is provided with a heat dissipation plate 13. The heat dissipation plate 12 is provided with a heat dissipation plate 13, and the heat dissipation plate 12 is provided with a heat dissipation plate 13. The heat dissipation plate 12 is provided with a heat dissipation plate 13, and the heat dissipation plate 12 is provided with a heat dissipation plate 13.

[0043] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
