Description

A new type of brake pad Technical Field

[0001] The utility model relates to the technical field of brake pads, in particular to a novel brake pad. Background Art

[0002] Current brake pads primarily utilize friction between the friction pads on the pad body and the brake disc to achieve deceleration. However, emergency braking often generates significant heat, which raises the temperature of the brake pad. This high temperature negatively impacts the lifespan of the pad. To mitigate this, existing technologies employ a thermal insulation layer on the back of the friction pad to prevent heat generated there from dissipating to the brake disc. However, due to limitations in the material of the thermal insulation layer, the thermal insulation layer is constantly exposed to the high temperatures generated by the friction pad, significantly shortening its lifespan.

[0003] To this end, solutions CN206309831U and CN215673313U increase heat dissipation holes and ventilation holes to remove heat more quickly. However, the ventilation holes have a small contact area and can only achieve passive heat dissipation. Moreover, the scattered holes make it difficult to form air circulation, resulting in poor overall cooling effect. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defects of the above-mentioned technology and provide a new brake pad.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is a new type of brake pad: including a brake pad, a curved pipe is provided inside the brake pad, the pipe is connected to the liquid inlet pipe and the liquid outlet pipe outside the brake pad, the liquid inlet pipe is connected to the power pump, and the power pump and the liquid outlet pipe are connected to the radiator; evenly distributed pillars are provided in the pipe.

[0006] As an improvement, the pillar is perpendicular to the plane of the brake pad.

[0007] The advantages of this invention over the prior art are that the coolant circulates in the pipe and comes out from the outlet pipe, taking the heat to the radiator, and then the coolant enters the brake pad through the inlet pipe and continues to circulate. The support plays the role of internal support and increases the contact area.

[0008] The new brake pad has a coolant that forms an internal circulation inside the brake pad, has a large contact area, actively and continuously cools down the brake pad, has a good cooling effect, and has high practical value and promotion value. BRIEF DESCRIPTION OF THE DRAWINGS
