Problems solved by technology
[0006] However, as mentioned above, when the brake is released, the conventional ball ramp type caliper parking brake that returns to the original position due to the elastic force of the seal ring 107, when a strong braking force is applied to the piston 103, the seal ring 107 is excessively deformed while losing part of the restoring force, and the piston 103 cannot be reset to the original position when the brake is released, thus hindering the rapid reset of the friction plate 105, so even if the brake is released, the friction plate 105 and the brake disc Contact is still maintained, so there is a problem of generating resistance
[0007] In addition, when the friction lining 105 is worn due to friction with the brake disc, the friction lining 105 does not come into contact with the brake disc at the initial stage of braking when the piston 103 advances and starts to pressurize the friction lining 105 . In order to achieve substantive braking, when the piston 103 advances to the maximum extent and presses the friction plate 105 to the maximum pressure of the brake disc, there is also a braking system where the braking pressure fails to reach the maximum pressure. bad question

Embodiment Construction
[0040] Hereinafter, a caliper type parking brake according to an embodiment of the present invention will be described with reference to the drawings.
[0041] as in figure 2Indicated by reference numeral 1 , the caliper parking brake of the present invention generally includes a caliper housing 3 , a braking force input end 5 , a braking force conversion end 7 , a braking force output end 9 and a braking end 11 .
[0042] Here, firstly, the above-mentioned caliper housing 3 is used as a part forming the outer body of the caliper type parking brake 1, such as figure 2 As shown, an air cylinder 13 for generating a braking force is formed at the rear end, and a shift fork 15 is disposed at the front end so as to face the air cylinder 13 to pressurize the brake disc 10 and bend in a right-angled direction.
[0043] The above-mentioned braking force input end 5 is used as the part that introduces the initial braking force to the caliper type parking brake 1, such as figure 2 ...

The invention relates to a caliper type parking brake. The caliper type parking brake comprises a caliper housing, a braking force input end, a braking force conversion end, a braking force output end and a braking end. When the friction plate wears, the initial position of the piston is advanced to compensate for the wear. According to the present invention, even if a large braking pressure is applied to the piston, the piston and the friction plate are reset to the original position when the brake is released, and the It can remove or reduce the resistance generated by the brake disc due to the contact with the unreset friction plate, and make the piston advance when the friction plate is worn to compensate for the distance from the brake disc caused by wear, thereby preventing the distance caused by wear. resulting in poor braking.
Description
technical field [0001] The present invention relates to a caliper type parking brake. More specifically, according to the strength of the braking pressure stuck at the output end of the braking force, the restoring force of the piston, etc., which resets to the position before braking when the brake is released, is increased or decreased, And remove or reduce the caliper type parking brake that produces the resistance in the brake disc due to the non-resetting of the friction plate pressurized by the piston. Background technique [0002] Generally, a caliper type parking brake is used as a brake that performs braking by pressing the brake disc between the piston and the friction plate of the shift fork by means of the braking force applied to the piston. The rotational force of the brake lever, which is pulled by the cable to rotate, is converted into linear motion to generate the braking force of the piston. [0003] At this time, caliper parking brakes can be classified i...
