Abstract

The invention discloses a gear-type EPB failure parking device, comprising an EPB shell, a brake disc and a caliper mechanism, wherein the EPB shell is provided with a mounting bracket and a synchronous belt, the mounting bracket is provided with a reed shell, a failure gear and a normally closed electromagnetic valve, the failure gear is provided with a normally open electromagnetic valve, the failure gear is rotatably connected with the mounting bracket and the failure gear is toothed with the synchronous belt; The normally closed solenoid valve is provided with a first clamp block, and thenormally open solenoid valve is provided with a second clamp block. A rotating shaft is arranged on the reed shell, and the rotating shaft is rotatably connected with the reed shell; A coil spring isarranged in the reed shell, one end of the coil spring is fixed with the reed shell, and the other end of the coil spring is fixed with the rotating shaft; The rotating shaft is provided with a firstclamping slot and a second clamping slot, wherein the first clamping block is clamped with the first clamping slot, and the second clamping block is clamped with the second clamping slot. The invention provides a gear-type EPB failure parking device for a new energy vehicle, which can realize parking under the condition of electric power failure and ensure driver safety.

Description

technical field [0001] The invention relates to the technical field of automobile braking, in particular to a gear type EPB failure parking device. Background technique [0002] The electronic parking brake system (EPB: Electrical Park Brake) measures the slope through the longitudinal acceleration sensor built in its computer, so that it can calculate the sliding force of the vehicle on the slope due to gravity, and the computer applies braking to the rear wheels through the motor. Power to balance the sliding force, so that the vehicle can stop on the slope. When the vehicle starts, the computer calculates the braking force that needs to be applied through the displacement sensor on the clutch pedal and the size of the accelerator. The computer automatically calculates the increase in engine traction and reduces braking force accordingly. When the traction force is enough to overcome the sliding force, the computer drives the motor to release the brake, so that the vehic...
