The invention relates to the technical field of engineering elements, in particular to a disc brake integrated with a parking function and a parking input and output characteristic calculation method. A guide bush is connected with a shell and an operation ejector rod, a pull arm is connected with the operation ejector rod, an actuator is connected with the shell, three steel balls are connected with the operation ejector rod and located in a roller path of the actuator respectively, a plane bearing is connected with the operation ejector rod and a screw rod, a threaded sleeve is connected with the screw rod, an inserting plate is connected with the threaded sleeve, a piston is connected with the threaded sleeve and the shell, a brake block is connected with a caliper body, and a brake disc is connected with the caliper body. The pull arm is rotated, so that the operation ejector rod can drive the steel balls to slide out of the roller path, the operation ejector rod drives the threaded rod to slide in the threaded sleeve until the threaded rod makes contact with the inserting plate and then pushes the piston, and the piston pushes the brake block to make contact with the brake disc. The larger the angle of rotating the pull arm is, the larger the braking force of the brake block to the brake disc is, and the problem that the hand braking force linearity of existing parking brakes is poor is solved.
Description
technical field [0001] The invention relates to the technical field of engineering components, in particular to a disc brake with integrated parking function and a calculation method for parking input and output characteristics. Background technique [0002] A parking brake is a device that has the function of slowing down, stopping or holding a moving part. It is a mechanical part that stops or slows down the moving parts in the machine. In the existing parking brake, the rocking arm is rocked so that the rocking arm triggers the brake calipers, thereby achieving the purpose of braking. However, the brake calipers can only be triggered by shaking the rocker arm to a preset position, and the braking force cannot be controlled according to the shaking degree of the rocker arm, that is, the linearity of the handbrake force of the parking brake is poor. Contents of the invention [0003] The purpose of the present invention is to provide a disc brake with integrated parking...
