Problems solved by technology

[0013] In addition, since the collet assembly is fixed with an independent fixture in the hydraulic chamber of the caliper, that is, the inserted collet assembly is fixed into the hydraulic chamber of the caliper, the hydraulic pressure of inserting the collet assembly into the caliper intracavity is difficult

Embodiment Construction

[0026] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Since the present embodiment can be modified in various ways by those skilled in the art, the present invention is not limited to the present embodiment.

[0027] 1 is a schematic structural view of an internal air discharge type ball-in-slope caliper type parking brake according to an embodiment of the present invention. According to an embodiment of the present invention, the parking brake includes: a parking unit 1 and a brake caliper 3 . The parking unit 1 is arranged in the compartment of the vehicle and is used for pulling the parking cable 2 connected with the wheels. Due to the pulling force applied by the parking unit 1, the brake caliper 3 uses the axial force generated when it rotates to generate the parking braking force and presses the brake pad 5 against the brake disc D, so through the pressure of the brake oil during braking And...

Abstract

According to the present invention, a cartridge assembly, which is inserted into an inner cylinder of a caliper housing and generates an axial force during parking braking, is fixed by a retainer outside caliper housing. Accordingly, a space occupying member for fixing is not provided in the inner cylinder of caliper housing, and for this reason, the inner cylinder can be more simply machined. Further, when air is discharged after the cartridge assembly is inserted into the caliper housing, air can smoothly flow in the inner cylinder of the caliper housing.

Description

technical field [0001] The present invention relates to a vehicle parking brake, in particular to a caliper type parking brake of an internal air discharge type with a ball-in-in-ramp (BIR, Ball-In-Ramp). Background technique [0002] In general, unlike brakes that apply pressure to the wheels by oil pressure generated by ordinary pedals, parking brakes that temporarily park the vehicle or stop the vehicle on an inclined place such as a hill are controlled by using a cable that is pulled by hand. Wheels apply pressure. The parking brake is operated via a parking lever located next to the driver's seat. [0003] Parking Brake Includes: Parking Lever, Parking Brake Cable and Equalizer. The parking lever is operated by hand. The parking brake cable is tensioned or loosened by a latch assembly (not shown) controlled by a release button located on the parking lever and releasing the brake. The equalizer is provided between the left and right cables connected to the left and r...
