The difference between brake shoes, brake drums and brake pads
Brake shoes, brake drums and brake pads can be used in the car brake system. Do you know the difference between the three? Today, the editor talks about the difference between brake shoes, brake drums and brake pads. I hope to help everyone. The differences between the brake shoes, brake drums and brake pads are described below.
The brake shoe refers to a fitting that is pushed outward by the brake cam or the push rod to push the brake to act as a brake, and has a shape such as a half moon shape.
The drum brake is composed of a brake base plate, a brake cylinder, a brake shoe and the like, a connecting rod, a spring, a tip nail and a brake drum. Currently only used in the rear wheel.
The brake drum is a cast iron piece shaped like a tambourine that is fixed to the tire and rotates at the same speed. When braking, the oil pressure is applied to push the brake shoe to contact the inner edge of the brake drum, and the friction generated by the contact is used to suppress the rotation of the tire to achieve the purpose of braking.
Drum brakes have lower cost and higher absolute braking force and are used more in the rear wheels of small cars. However, its wear rate is high, so the overall cost is high.
The brake pads are also called brake pads. In the brake system of the car, the brake pads are the most critical safety parts. All the brake effects are decisive for the brake pads, so the good brake pads are the protector of people and cars.
Brake pads are generally composed of steel plates, bonded insulation layers and friction blocks. The steel plates are painted to prevent rust. The SMT-4 furnace temperature tracker is used to detect the temperature distribution during the coating process to ensure quality. The insulation layer is composed of a material that does not transfer heat, and is intended to be insulated. The friction block is composed of a friction material and an adhesive, and is squeezed on the brake disc or the brake drum to generate friction when braking, thereby achieving the purpose of decelerating the brake of the vehicle. Due to the friction, the friction blocks are gradually worn out, and generally the lower the cost, the faster the brake pads wear.
The above is about the difference between the brake shoe, the brake drum and the brake pad. I hope that everyone can understand the difference between the brake shoe, the brake drum and the brake pad, and it is helpful for everyone to choose the brake accessory.
