Jiaozuo brake

The caliper disc brake can be divided into fixed caliper disc type and floating caliper disc type according to the structural type of the brake caliper.

Caliper disc brake

The brake disc is fixed to the wheel hub, and the brake caliper 5 is fixed to the axle, which cannot rotate or move axially along the brake disc. The brake caliper is equipped with two brake wheel cylinder pistons 2, which press against the brake pads on both sides of the brake disc. When the driver steps down the brake pedal to brake the car, the brake fluid from the brake master cylinder is pressed into the brake wheel cylinder, the hydraulic pressure of the brake wheel cylinder rises, the pistons of the two wheel cylinders move to the brake disc under the hydraulic pressure, press the brake block against the brake disc, and the brake block clamps the brake disc to generate Friction torque to prevent the wheel from rotating, so as to achieve braking.

The brake caliper of caliper disc brake is floating and can move axially relative to the brake disc. Figure 3 shows the structure diagram of floating caliper disc brake. one thousand five hundred and forty-five trillion and ninety-seven billion eight hundred and thirty-two million three hundred and eighty-six thousand five hundred and twenty

YQP hydraulic disc brake

The brake caliper is generally designed to move axially relative to the brake disc. There is a hydraulic oil cylinder on the inner side of the brake disc, and a fixed brake block on the outer side is attached to the caliper body. When braking, the brake fluid is pressed into the oil cylinder, and under hydraulic pressure, the piston moves to the left, pushing the movable brake pad to move to the left and press against the brake disc. Therefore, the brake disc gives the piston a reaction force to the right, causing the piston and brake caliper body to move to the right along the guide pin 2, until the fixed brake pad 5 on the left side of the brake disc is also pressed onto the brake disc. At this time, the brake pads on both sides are pressed on the brake disc, and the brake pads clamp the brake disc to generate Friction torque that prevents the wheels from rotating, so as to achieve braking.

Compared with the disk brake, the heat dissipation of the drum brake is much worse. The stability of the brake force of the drum brake is poor. The brake force varies greatly on different roads, and it is not easy to control. Due to poor heat dissipation performance, a large amount of heat will accumulate during the braking process. The brake pads and wheel drums are prone to extremely complex deformation under the influence of high temperatures, which can lead to brake decay and vibration, leading to a decrease in braking efficiency. In addition, after using the drum brake for a period of time, it is necessary to regularly adjust the gap between the brake shoes, and even remove the entire brake drum to clean the accumulated brake powder. Of course, drum brakes are not useless either. They are cheap in cost, have high braking force, and conform to traditional design. During the braking process of a four-wheel sedan, due to inertia, the load on the front wheels usually accounts for 70% -80% of the total load of the car. The braking force on the front wheels is greater than that on the rear wheels, and the rear wheels play an auxiliary braking role. Therefore, in order to save costs, car manufacturers adopt a braking method of front disc and rear drum. However, for heavy vehicles, because the speed is generally not very high, the durability of brake shoes is also higher than that of disc brakes, and the braking force is large, many heavy vehicles still use the four-wheel drum design today
