The Difference Between Brake Shoe, Brake Pad, brake shoe and brake drum

TIME:2020.01.16
Brake shoes, brake pads, brake shoes and brake drums are the materials that create pressure and friction for the brake disc / Drum, and so are the brake pads. The brake drum, also known as the brake drum, is the friction of the brake shoes. Let's find out what the difference is between these four product terms. Brake Shoe, brake shoe is one of the key safety parts in the automobile brake system, which is mounted on the brake drum and is pushed outward by the action of Brake Cam or push rod. The shape of the brake shoes is like a half-moon. When you step on the brake shoes, the two half-moon shaped brake shoes will stretch out under the action of the brake cylinder. The brake shoes will rub against the inner wall of the brake drum to slow down or stop the car. Brake pads. Brake pads are also called brake pads. In the brake system of automobile, the brake pad is the key safety part, all the brake pad plays a decisive role, so the good brake pad is the patron saint of people and cars. Brake pads are generally made of steel plates, bonded insulation, and friction blocks, in which the insulation is made of non-heat-transfer material, designed to insulate. 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. After the friction material uses up, must replace the brake pad promptly, otherwise the steel plate and the brake disc will contact directly, will lose the brake effect and damage the brake disc. A brake drum is a cast iron 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. Brake shoes, brake shoes are drum brake friction couplings, in addition to as a component of the required strength and stiffness, there should be as high and stable Coefficient of friction, and appropriate wear resistance, heat resistance, heat dissipation and heat capacity.
