Working principle of brake drum
The working principle of the drum brake is: when the driver steps on the brake pedal, the piston of the master cylinder will move outward, thereby generating pressure in the oil circuit, and the brake fluid transmits the pressure to the brake wheel cylinder to make the wheel The pistons at both ends of the cylinder apply force to the shoe ends of the left and right brake shoes at the same time, and the force is equal. Because the wheel is rotating, the pressure of the brake drum on the brake shoe is asymmetrical, resulting in self-increasing or self-decreasing force.
What is a brake drum?
The brake drum is a part of the automobile braking system, which is used to convert the kinetic energy of the automobile into heat energy through friction to slow down or stop the automobile. There are two types of brake drums: disc brakes and drum brakes. In recent years, due to the increase in the speed of automobiles, the use of disc brakes has become more and more common. The design of the brake drum needs to consider its wall thickness and heat dissipation to increase strength and reduce temperature.
Material of the wheel hub
