Description

Technical Field

[0001] The utility model relates to the technical field of automobile brake pads, in particular to a ductile iron steel back of an automobile brake pad. Background Art

[0002] In the braking system of a car, the brake pad is the most critical safety part. The brake pad plays a decisive role in all braking effects. Brake pads are generally composed of steel backing, adhesive insulation layer and friction block. The steel backing mainly plays the role of fixing and supporting the friction block in the brake pad of the car. The purpose of braking is achieved by applying pressure between the fixed brake pad and the brake disc that rotates with the wheel to generate friction. The friction force is generated by the friction between the friction block and the brake disc, and the friction force prevents the wheel from rotating and brakes.

[0003] However, most existing steel backs have insufficient heat dissipation capabilities. For example, in the utility model with patent number CN206571859U, due to continuous or frequent braking, the contact between the brake pad and the brake disc will generate a large amount of heat. This high temperature environment will cause the temperature of the brake pad to rise sharply. The steel back, as a supporting structure, fits tightly with the brake pad, so it will inevitably receive a large amount of heat energy from the brake pad. Since the steel back has no effective active heat dissipation mechanism, its cooling will rely entirely on air convection in the environment, that is, it only relies on wind to take away the heat.
