Abstract

The invention discloses an integral type electrical park brake (EPB) driving device of parking brake. The integral type EPB driving device comprises a rotating shaft and a driving assembly for drivingthe rotating shaft to rotate; two synchronous worms are arranged on the rotating shaft, the synchronous worms can apply acting force on two corresponding brake pistons through corresponding transmission assemblies, the brake pistons are arranged in parallel to each other, the force-bearing surfaces of the brake pistons move facing brake pads, acting force of spring piece clips fixedly connected with the brake pads are overcome, and the brake pads are pressed on the surfaces of brake discs; and when parking is released, the transmission assemblies move in the direction back on to the brake pads, the brake pads move backwards under counter-acting force of the spring piece clips, and the brake pistons are pushed to move backward synchronously. The integral type EPB driving device of the parking brake is characterized in that the structure is reasonable, the design is novel, the two brake pistons are synchronously pressed on the brake pads, and reduplicated parking braking force can be generated, so that requirements of the parking brake can be met; and meanwhile, the device is compact in structure, small in size and convenient in installation and debugging, the control response is quick, and maintenance of a vehicle is convenient.

Description

technical field [0001] The invention relates to the technical field of automobile parking brakes, in particular to an integrated EPB drive device for parking brakes. Background technique [0002] With the continuous deepening of the application of electronic and electronic control technology in the automobile industry, the mechatronics integration of auto parts products has become the mainstream of development. The electronic parking brake (EPB) replaces the traditional purely mechanical cable-type parking device, which not only brings comfort to customers, but also improves the safety of parking brake. The main function of EPB is to keep the vehicle stationary on the slope after the vehicle is parked, and to provide auxiliary braking force when the vehicle is started on the slope and emergency braking is required. The current mainstream EPB can be divided into caliper-integrated EPB and cable-type EPB. [0003] The caliper integrated EPB is usually driven by a motor to re...
