Between a Brake Shoe, a brake pad and a brake drum
TIME：2020.01.09
Brake shoe is the action of Brake Cam or push rod and is pushed outward to press brake drum brake function of accessories, its shape is like a half moon. Brake pads are also called brake pads. In the brake system of automobile, the brake pad is the most important safety part, all the brake pad plays a decisive role, so the good brake pad is the patron saint of people and cars. Brake lining is generally made up of steel plate, adhesive heat insulation layer and friction block. The steel plate is coated to prevent rust. SMT-4 furnace temperature tracker is used to measure the temperature distribution during the coating process to ensure the quality. The insulating layer consists of a material that does not transmit heat for the purpose of insulation. The friction block is composed of friction material and adhesive. When braking, the friction is squeezed on the brake disc or the brake drum to achieve the purpose of decelerating the braking of the vehicle. As a result of friction, friction block will be gradually wear, generally speaking, the lower the cost of the brake pad wear faster. A 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, oil pressure is used to push the Brake shoe to contact the inner edge of the Brake drum, and the friction generated by the contact is used to restrain the rotation of the tire to achieve the purpose of braking. The drum brake is composed of a brake floor plate, a brake pump, a brake shoe and other relevant connecting Rod, a spring, a pin and a brake drum. Currently only commonly used in the rear wheel. Drum brakes, which are cheaper and have higher absolute braking power, are more commonly used in the rear wheels of small cars. But its attrition rate is higher, therefore at the same time the overall cost is higher.
