BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parking brake, and more particularly, to a ball-in-lamp brake caliper type parking brake, which compensates for an invalid stroke generation area and improves parking efficiency.

In general, parking brakes used when stopping on inclined road surfaces such as temporary parking of vehicles or hilly roads are pulled by hand, unlike brake devices that press wheels by using hydraulic pressure generated by conventional pedals. It is designed to pressurize the wheel using a cable and operate by operating the parking lever provided on the side of the driver's seat.

The parking brake is a parking brake that is pulled or loosened by a latch assembly (not shown) which is operated according to the operation of a parking lever that is held and operated by a hand and a release knob provided to the lever to release the brake function. It is composed of an equalizer provided between the cable and the left and right cables connected to the left and right rear wheel brakes to distribute the equal operating force.

Such parking brakes typically use a method having a locking function through a strong adhesion generated by pressing the pad toward the drum mounted on the wheel using the parking brake operating force.

In addition, instead of pressing the pad toward the drum, a caliper is used to place the disc plate between the pads to perform braking. A caliper that applies a braking force to the disc plate while configuring the parking brake is also used. Is commonly called a BIR Caliper.

As the BIR caliper pulls the parking brake, the axial movement force is generated inside the BIR caliper through the parking cable. That is, the pulling force of the parking cable is converted into the rotational force of the ramp. By changing the position of the ball, an axial movement force generated by the opposite ramp is generated in accordance with the movement of the ball, and this axial movement force presses the pad toward the disc plate to form the parking braking force. do.

In other words, BIR caliper is the sequence of cable operation → lever rotation → input (rotary) lamp rotation → rolling motion of ball → rotation of output (thrust) lamp → clutch rod forward → piston forward → friction brake (disengage disk rotation) when parking Parking braking.

Here, a spring or the like together with an input / output lamp, which is a component assembled inside the caliper, is commonly referred to as a cartridge assembly. The cartridge assembly is fixed to the outside by being fitted to the caliper body by combining components to improve assemblability. In addition to the spring seat, an O-ring for oil tightness inside the caliper is applied.

However, this BIR caliper is convenient for parking efficiency and layout of the parking cable, but has a weak point in the assembly structure, and in particular, the one-piece cartridge type has a slight lack of lamp holding force to the caliper. This will be.

Accordingly, the present invention has been invented in view of the above-mentioned point, and in addition to assembling a cartridge assembly that generates an axial movement force while forming a BIR caliper (Ball In Ramp Caliper) to a caliper without using a jig, The purpose is to enhance the assembly force while strengthening the clamping force of the lamp caliper.

In addition, the BIR caliper of the present invention (Ball In Ramp Caliper) is to enhance the holding force of the cartridge assembly to the caliper to suppress the invalid stroke generated in the cartridge assembly during operation, to increase the parking efficiency is also the purpose have.

The present invention for achieving the above object, the ball-in-lamp brake caliper-type parking brake is projected out of the caliper so that one side is coupled via the parking cable and the flange nut, the other side is located toward the piston to push the pad A cartridge assembly installed in the internal hydraulic pressure forming space of the caliper,

An input lamp connected to the parking cable via a flange nut from the outside through the distal end of the caliper while forming the cartridge assembly is fixed to the caliper with a fastening member, wherein the fastening member is disposed at an intermediate portion of the hole drilled in the distal end body of the caliper. And is configured to form a clamping force between the input lamp shaft and the caliper of the input lamp.

To this end, the fixing member is inserted into a fixing groove cut into the input lamp shaft of the input lamp, the ball is fitted into the ball seating groove is cut into the hole of the caliper which the input lamp shaft exits, and the elastic force while wrapping the ball Consists of a release spring for pushing the ball.

Here, the ball is characterized in that formed in a polygonal cross section.

According to the present invention, the convenience of being able to assemble without using a jig by changing the assembly structure for the caliper of the lamp constituting the cartridge assembly forming the BIR caliper (Ball In Ramp Caliper) generating axial movement force, as well as for the caliper The clamping force of the lamp can be strengthened to reduce the invalid stroke generated from the cartridge assembly.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Since the exemplary embodiments of the present invention may be implemented in various different forms, one of ordinary skill in the art to which the present invention pertains may be described herein. Not limited to the embodiment.

1 is a block diagram illustrating a parking brake of a ball-in-ramp brake caliper type vehicle according to the present invention. The BIR caliper of the present invention implements parking braking using a caliper together with a main brake action. To this end, the caliper 1 has a cartridge assembly 2 which generates an axial movement while rotating when the parking cable is pulled, and moves the piston Pi which pushes the pad toward the disc by the axial movement.

Further, in order to operate the cartridge assembly 2, a parking cable having one end connected to the cartridge assembly 2 and the other end connected to the parking handle is provided, and the operation force of the parking handle is evenly pulled toward the left and right wheels. It also has an equalizer.

In addition, the cartridge assembly (2) is protruded out of the caliper (1) so that one side is coupled via the parking cable and the flange nut (14), the other side is located toward the piston (Pi) to push the pad, the caliper It is installed in the internal hydraulic pressure forming space of (1).

This cartridge assembly 2 has an output lamp 4 between the lamps 3 and 4, along with an output lamp 4 which pushes the piston Pi and an input lamp 3 which is rotated via the parking cable. Ball plate 5 having a ball for moving the shaft in an axial direction.

In addition, the cartridge assembly 2 includes a holder housing 8 surrounding the input / output lamps 3 and 4 and the ball plate 5, and a spring 7 and an output lamp 4 for generating elastic restoring force. It further comprises a clutch rod 6 for switching the rotation of the linear movement.

In addition, the cartridge assembly 2 is provided with an o-ring 13 for airtightness of oil filled in the hydraulic space of the caliper 1, and maintains the fastening of the cartridge assembly 2 in the caliper 1. It is further provided with a spring sheet 9 which is fixed to the caliper 1, which is a typical configuration of a BIR caliper.

In addition, the cartridge assembly 2 further includes a fixing member 10 for penetrating the distal body of the caliper 1 to fix the input lamp shaft 3a to which the parking cable is connected. ) Firmly secures the input ramp shaft 3a to the caliper 1 so as to enhance the fixing force of the input lamp 3 with respect to the caliper 1, as well as to suppress the generation of an invalid stroke through the spring seat 9 portion. do.

This is because the invalid stroke is caused by the forward and return action occurring in the cartridge assembly 2, so that the cartridge assembly 2 by oil filled in the hydraulic space of the caliper 1 when the fixing member 10 is operated. Overcoming the power of the will be done.

To this end, the fixing member 10, together with the ball (11) fitted into the fixing groove (3b) cut into the input lamp shaft (3a) of the input lamp 3, the release spring surrounding the ball ( 12).

In this case, the ball 11 is formed in a polygonal cross section instead of a circular cross section, and the release spring 12 provides an elastic force that protrudes from the fixing groove 3b of the input lamp shaft 3a in an assembled state.

The use of such a fastening member 10 will generally eliminate the use of a retainer (or fastening ring) for fastening the input lamp 3 to the caliper 1.

In addition, the use of the fixing member 10 is formed with a seating groove 1b that extends more broadly the inlet portion through which the chamfer in the caliper 1, that is, the input lamp shaft 3a of the input lamp 3 exits, The o-ring 13 is fitted into the seating groove 1b while the input lamp shaft 3a is inserted.

In addition, a ball seating groove 1c into which the fixing member 10 is fitted is further formed in the hole into which the input ramp shaft 3a is inserted, and the ball seating groove 1c is formed in the tip body of the caliper 1. It is formed as an intermediate portion, so that the input ramp shaft 3a can be fixed at an intermediate length.

Then, the fixing groove (1a) is formed on the side of the hydraulic space of the caliper (1), which acts to ensure the spring sheet 9 to secure the fixing force to the galley (1) by using a projection.

As described above, the mounting groove 1b, which is an inlet portion of the through hole through which the input lamp 3 exits, forms a tip body connected to the hydraulic space of the caliper 1, and thus, the cartridge at the time of assembly as shown in FIG. When the input lamp shaft 3a of the input lamp 3 constituting the assembly 2 is taken out, the input lamp shaft 3a can be more easily pulled out without using a separate jig.

When the cartridge assembly 2 is assembled, if the input lamp shaft 3a of the input lamp 3 comes out of the tip body of the caliper 1, the cartridge assembly 2 is fitted into the fixing groove 3b of the input lamp shaft 3a. The ball 11 is fitted into the ball seating groove 1c formed in the caliper 1.

That is, when the input ramp shaft 3a exits with the ball 11 entering the fixing groove 3b by the release spring 12 pressed through the caliper 1, the input ramp shaft 3a As the ball 11 fitted into the fixing groove 3b is raised by the elastic restoring force applied by the release spring 12, the ball 11 is fitted into the ball seating groove 1c formed in the caliper 1 and is fixed.

At this time, as the cross section of the ball 11 forms a polygonal cross section instead of a circular cross section, a strong fixing force is provided between the fixing groove 3b of the input ramp shaft 3a and the ball seating groove 1c of the caliper 1. When the spring sheet 9 receives the compression / expansion force of the o-ring 13 during braking, the forward force of the cartridge assembly 2, which moves forward and returns, is overcome so that the spring seat 9 is caliper ( 1) This is due to the fact that no invalid stroke is generated because a gap is not formed.
