Description

Car parking brake with increased mounting force {MOUNTING-IMPROVED PARKING BRAKE FOR VEHICLE}

The present invention relates to a parking brake for a vehicle with enhanced mounting force, and more particularly, a lamp mounted on a caliper housing to support rotation of a shaft to be mounted on a caliper housing by a double concave-convex coupling method, thereby providing a lamp and a caliper housing. The present invention relates to a parking brake for a vehicle in which a mounting force is enhanced so as to prevent the breakage of the mounting part easily by increasing a coupling force therebetween.

In general, the parking brake for a vehicle fixes the disk that rotates together with the wheel of the vehicle by friction or the like by using a caliper. Such a friction parking brake is disclosed in Patent Document 1.

Conventional vehicle parking brakes, as shown in Figures 1 and 2, a disk (1) that rotates with the wheel of the vehicle, and a carrier (not shown) coupled to the vehicle body to be pressed on the inner / outer surface of the disk (1) The inner and outer disk pads 2 and 3 movably installed on the caliper, the caliper housing 100 slidably installed on the carrier to operate the inner disk pad 2, and the caliper housing 100 inside the caliper housing 100. A piston 110 that is retractably installed, and an actuator 120 that is installed in the caliper housing 100 to operate the piston 110.

In particular, the actuator 120 is installed in the chamber 130 of the caliper housing 100 to be connected to the parking cable, as shown in FIGS. 1 and 2, and the piston 110 interlocks with the parking cable to form an inner disk pad ( To 2). The actuator 120 includes an operating shaft 122 to which the lamp 121 fixedly installed in the chamber 130, the operation lever 4 connected to the parking cable are coupled, and the lamp 121 and the operating shaft 122. A ball 123 interposed therebetween, a push rod 124 pushed by the operating shaft 122 to pressurize the piston 110, and a return spring 125 for returning the push rod 124 to its original position. And a cage 126 provided for installing the return spring 125.

In addition, the lamp 121 supports the operating shaft 122 such that the operating shaft 122 which rotates as the operating lever 4 rotates pushes the piston 110 via the ball 123. To this end, the lamp 121 should not rotate. To prevent the lamp 121 from rotating, a recess 121b is formed in the lamp 121, and the recess 110a may be fitted into the caliper housing 100. ) Is formed.

However, these conventional parking brakes have the following problems.

1) The iron, which prevents the lamp from rotating, is subjected to shearing force due to frequent operation of the operating lever, which often causes the iron to break.

2) Breakage of the steel part does not push the cylinder even if the operating shaft is rotated by the operating lever. Consequently, the brake pad cannot be pressed to generate the braking force.

3) As the braking force is not generated, the function of the parking brake is lost, which may cause a safety accident.

In particular, the concave-convex portion is characterized in that it has an elliptical cross section and includes an iron portion protruding from the lamp.

According to the on-vehicle parking brake of the mounting force of the present invention has the following effects.

1) Since the lamp and the caliper housing are double-coupled, it is possible to prevent the uneven portion of the lamp from being damaged even in the shear force generated by the operation of the operation lever repeatedly.

2) This can induce the actuator to operate smoothly during the operation of the operating lever can improve the safety of the parking brake.

3) By forming the convex portions of the portions to be concave and convex to have an elliptical cross section, the contact cross-sectional area of the double concave-convex coupling can be further widened, and thus the bonding force can be further improved.

4) It is possible to prevent the lamp from being damaged so that the life of the parking brake can be extended.

5) By manufacturing the lamp by the forging method, not only the lamp can be easily manufactured but also the manufacturing cost can be reduced.
