Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to an improved noise-reducing brake pad. Background Art

[0002] Automobile brake pads, also known as automobile brake leathers, refer to friction materials fixed on the brake drum or brake disc that rotates with the wheel. The friction lining and friction lining block bear external pressure, generating friction to achieve the purpose of vehicle deceleration. Automobile brake pads are generally composed of steel plates, adhesive insulation layers and friction blocks. The steel plates must be coated to prevent rust. The SMT-4 furnace temperature tracker is used to detect the temperature distribution of the coating process to ensure quality. The insulation layer is composed of non-heat-conducting materials for the purpose of heat insulation. The friction block is composed of friction materials and adhesives. When braking, it is squeezed on the brake disc or brake drum to generate friction, thereby achieving the purpose of vehicle deceleration and braking. Due to friction, the friction block will gradually wear out. Generally speaking, the lower the cost of the brake pad, the faster it wears. After the friction material is used up, the brake pad should be replaced in time, otherwise the steel plate will directly contact the brake disc, and eventually the braking effect will be lost and the brake disc will be damaged. The working principle of the brake is mainly from friction. The friction between the brake pad and the brake disc (drum) and the tire and the ground is used to convert the kinetic energy of the vehicle into heat energy after friction to stop the vehicle. A good and efficient braking system must be able to provide stable, sufficient and controllable braking force, and have good hydraulic transmission and heat dissipation capabilities to ensure that the force applied by the driver from the brake pedal is fully and effectively transmitted to the master cylinder and each sub-cylinder, and to avoid hydraulic failure and brake decay caused by high heat. The braking system on the car is divided into two categories: disc and drum, but in addition to the cost advantage, the efficiency of drum brakes is far less than that of disc brakes.

[0003] The application number is CN201420663930.0, which discloses a motorcycle brake pad, including a steel back and a friction substrate pressed on the surface of the steel back, and a plurality of mutually parallel chip grooves are arranged on the surface of the friction substrate, characterized in that: the chip grooves are arranged in an oblique direction, and the angle between the chip grooves and the left-right symmetrical center line of the brake pad is 25-35 degrees; the steel back surface is provided with multiple rows and columns of rake teeth embedded in the friction substrate, the rake teeth are triangular saw teeth, and the setting direction of the rake teeth is the same as the direction of the shear force to which the brake pad is subjected when working. The utility model is more conducive to chip removal during braking, and can greatly enhance the bonding force between the friction substrate and the steel back surface, meet the requirements of high shear force to which the friction substrate is subjected when braking, and is particularly suitable for brake pads produced by cold pressing.

[0004] Although the above-mentioned utility model is arranged in a diagonal direction through the chip groove, the angle between the chip groove and the left-right symmetrical center line of the brake pad is 25-35 degrees; the steel back surface is provided with multiple rows and columns of rake teeth embedded in the friction substrate, the rake teeth are triangular saw teeth, and the setting direction of the rake teeth is the same as the direction of the shear force to which the brake pad is subjected when working, so that the device is more conducive to chip removal during braking, and at the same time can greatly enhance the bonding force between the friction substrate and the steel back surface, meet the requirements of high shear force on the friction substrate during braking, and is particularly suitable for brake pads made by cold pressing, but there is a disadvantage that when the device fails unexpectedly, it cannot avoid the harm to the driver in an emergency.

[0005] Therefore, it is necessary to install an emergency brake component on the device so that when the brakes fail on the vehicle body on which the device is installed, the dangerous situation can be avoided by the spare emergency brake component. This component can be used to stop the vehicle in an emergency and avoid life-threatening consequences caused by speed failure. Utility Model Content
