Hengyang Heavy Industry SBD200-A Hydraulic Safety Brake with Special Disc Spring Applied Force

Caliper disc brake has strong heat dissipation ability and good thermal stability, so it is widely used in most cars and light trucks.

Caliper disc brake can be divided into fixed caliper disc type and floating caliper disc type according to the caliper structure type.

Fixed Caliper Disc Brake

Fixed caliper disc brake caliper fixed mounted on the axle, can not rotate, but also can not move along the direction of the brake disc axis, which must be installed in the brake disc on both sides of the brake block to promote the device (for example, equivalent to the brake wheel cylinder hydraulic cylinder), in order to separate the two sides of the brake block pressed to the brake disc.

Figure 1 shows the structure of a caliper disc brake. Brake disc 1 fixed on the hub, brake caliper 5 fixed on the axle, can neither rotate nor move axially along the brake disc. Brake caliper is equipped with two brake wheel cylinder piston 2, were pressed on both sides of the brake disc brake block 3. When the driver steps on the brake pedal to make the car brake, brake fluid from the brake master cylinder is pressed into the brake wheel cylinder, brake wheel cylinder hydraulic pressure rises, the two wheel cylinder piston in the hydraulic pressure under the action of the brake disc to move to the brake block pressure against the brake disc, brake block clamping the brake disc to prevent the wheel from rotating friction torque, to achieve the brake. Brake.
