What do brake calipers do

The brake caliper is a caliper device with functions such as decelerating, stopping or keeping the moving wheel in a stopped state, and is generally only used in disc brake systems. The working principle of disc brakes can be described by a plate. When the rotating plate is pinched with the thumb and index finger, the plate will stop rotating. The thumb and index finger play the role of the brake caliper. Disc brakes on cars are composed of a brake oil pump, a brake disc connected to the wheel, and brake calipers on the disc. When braking, the high-pressure brake fluid pushes the piston inside the caliper, pressing the brake shoe against the brake disc to produce a braking effect. Disc brakes are divided into two types: ordinary disc brakes and ventilated disc brakes. Ventilated disc brakes reserve a gap between the two brake discs to allow airflow to pass through the gap. Some ventilated discs also drill many circular ventilation holes on the disc surface, or cut ventilation slots on the disc surface. Or prefabricated rectangular vents. Ventilated disc brakes take advantage of air flow, and their cooling and heating effects are better than ordinary disc brakes. The main advantage of disc brakes is that they can brake quickly at high speed, the heat dissipation effect is better than that of drum brakes, the stability of braking efficiency is good, and it is easy to install advanced electronic equipment like ABS.
According to the movement mode of the brake caliper, floating caliper brakes can be divided into sliding caliper disc brakes and swing caliper disc brakes, among which sliding caliper disc brakes are more widely used. The characteristics of the sliding caliper disc brake are: the brake caliper can slide axially relative to the brake disc; only the oil cylinder is set on the inner side of the brake disc, and the outer brake block is attached to the caliper body. Secondly, for fixed brakes, it is a fixed caliper disc brake.
The brake caliper body 5 straddled on the brake disc 1 is fixedly installed on the axle 6, and it cannot rotate or move along the axis of the brake disc. side. When braking, the brake oil enters the two connected hydraulic chambers in the caliper body from the brake master cylinder (brake master cylinder) through the oil inlet 4, and presses the brake blocks 3 on both sides to be fixedly connected to the wheels. the brake disc 1 to generate braking.
This kind of brake has the following shortcomings: there are many oil cylinders, which makes the structure of the brake caliper complex; the oil cylinders are located on both sides of the brake disc, and must be connected by the inner oil passage or external oil pipe of the caliper spanning the brake disc, which makes the brake The size of the caliper is too large to be installed in the rim of a modern car; when the thermal load is large, the brake fluid in the oil cylinder and the oil pipe or oil passage across the brake disc is easily vaporized by heat; if it is to be used as a parking brake, it must be Add a mechanically actuated parking brake caliper.
