Abstract

The invention discloses a pneumatic disc type brake capable of bidirectionally adjusting a brake clearance. The pneumatic disc type brake capable of bidirectionally adjusting the brake clearance comprises an air chamber, a brake disc, a brake part for an inner friction disc and an outer friction disc arranged on two sides of the brake disc, a clamp body matched with the outer friction disc, an external programmable logic controller (PLC), a clearance adjustment piece matched with the air chamber, a temperature sensor arranged above the brake part, and a power part matched with the clearance adjustment piece. The clearance adjustment piece comprises a drive rod in running fit with the clearance adjustment piece and matched with the inner friction disc; a holder fixedly connected onto the clamp body is arranged on the outer side of the brake part; the temperature sensor is fixedly connected to the side surface, close to the brake part direction, of the holder; and the external PLC is electrically connected with the temperature sensor and the power part through a wire harness. According to the pneumatic disc type brake capable of bidirectionally adjusting the brake clearance providedby the invention, the dragging abrasion and the abnormal heating of the brake and even the occurrence of the dangerous situation of spontaneous combustion caused by an undersize clearance can be effectively reduced, and the economic loss is reduced; and the brake clearance can be bidirectionally adjusted, and meanwhile, the pneumatic disc type brake capable of bidirectionally adjusting the brake clearance is stable in performance and reliable to adjust.

Description

technical field [0001] The invention belongs to the technical field of application of pneumatic disc brakes, in particular to a pneumatic disc brake capable of bidirectionally adjusting the braking gap. Background technique [0002] With the development of technology, pneumatic disc brakes are increasingly used in large commercial vehicles to replace traditional drum brakes. Compared with drum brakes, air disc brakes have better stability and thermal decay performance. In the pneumatic disc brakes currently on the market, due to the wear of the inner friction plate, outer friction plate and brake disc, when the working brake clearance increases, the brake itself can automatically compensate to the normal working clearance; but when the brake clearance When the gap is smaller than the normal working gap, the internal gap of the brake cannot be automatically increased. If the gap is too small, it will cause the brake to wear, abnormal heat, and even the risk of spontaneous co...
