Description

Bracket for locking caliper in disk brake}

The present invention relates to a bracket for fixing a caliper of a disc brake, and more particularly, to a bracket configured to be mounted on any kind of vehicle, a four-piston caliper generating a braking force by the operation of four pistons.

The disc brake is configured to generate a braking force by compressing the pad to the disc rotor, and a piston is used as a means for pushing the pad to press the pad to the disc rotor. In the early days of disc brakes, only one piston was provided, but the number of pistons is gradually increasing to improve braking power and sensitivity. Is being used.

At this time, in order to fix the position of the caliper, a bracket is required to which one side is coupled to the caliper and the other side is coupled to the knuckle of the disc rotor. It is also different.

Hereinafter, a conventional four-piston caliper fixing bracket will be described with reference to the accompanying drawings.

1 is a perspective view of a conventional caliper fixing bracket, Figure 2 is a plan view of a conventional caliper fixing bracket.

As shown in FIGS. 1 and 2, the conventional caliper fixing bracket 10 includes a first horizontal member 11 and a second horizontal member 12 and a first horizontal member 11 spaced apart from each other by a predetermined distance. And a connecting member 13 connecting one end of the second horizontal member 12.

The first horizontal member 11 is formed with a pair of first caliper coupling holes 14 and one knuckle coupling hole 15 for engagement with the caliper, and the second horizontal member 12 has another caliper A pair of second caliper coupling holes 16 for coupling are formed. At this time, the bracket 10 is mounted so that the disc rotor is inserted between the first horizontal member 11 and the second horizontal member 12.

Also, as shown in FIG. 2, the knuckle coupling hole 15 is positioned at an angle shifted from a line connecting the center points of the pair of first caliper coupling holes 14.

FIG. 3 shows an example of use of a four-piston caliper mounted on a disc rotor applied to another type of vehicle using a conventional bracket.

When the four-piston caliper 20 is coupled to the conventional bracket 10 and mounted on the disc rotor 30 applied to other types of vehicles, the knuckle hole 42 of the knuckle 40 is shown in FIG. 3. And the knuckle coupling holes 15 do not coincide with each other and are spaced apart from each other. Therefore, the user has a problem that it is impossible to fasten the four-piston caliper 20 to the disc rotor applied to other types of vehicles by using the conventional bracket 10.

Therefore, when a user of a vehicle in which the four-piston caliper 20 is not provided as a basic specification wants to mount the four-piston caliper 20 to his vehicle, the knuckle 40 and the bracket 10 may be removed. It is necessary to provide a separate coupling member for connecting. If a separate coupling member is used, the weight of the coupling member is added to the vehicle, and the weight of the vehicle body increases when the coupling member is entered for each wheel. In particular, increasing the load of the wheel portion not only lowers fuel economy but also serves to lower the performance of the braking, which is not preferable.

In addition, since the bracket having the above structure does not have a configuration for dissipating heat generated by friction between the pad and the disc rotor to the outside, the temperature of the pad and the disc rotor is increased to promote the wear of the pad and to reduce the braking force. There was also a disadvantage.

The present invention has been devised to solve the above problems, and is designed to mount a four-piston caliper, regardless of the vehicle type, and to provide a bracket configured to more effectively dissipate the frictional heat generated during braking have.

Caliper fixing bracket according to the present invention for achieving the above object, the first caliper coupling hole and the knuckle coupling hole is formed and the first horizontal member which is bent at a predetermined angle to the side where the knuckle coupling hole is formed, And a second horizontal member having a caliper coupling hole spaced apart from the first horizontal member by a predetermined distance, and a connecting member connecting one end of the first horizontal member on the opposite side where the knuckle coupling hole is formed to one end of the second horizontal member. do.

The first horizontal member may include two or more first caliper coupling holes in a line, and a line connecting the centers of the knuckle coupling holes and the adjacent first caliper coupling holes may be connected to a line connecting the centers of the different first caliper coupling holes. It is formed to intersect at an angle of less than the degree.

In this case, two or more knuckle coupling holes may be formed in the first horizontal member.

In addition, the connection member is formed with one or more heat sinks for dissipating heat generated during braking.

In addition, the caliper fixing bracket according to the present invention is made of a duralumin-based high strength aluminum alloy.

Hereinafter, an embodiment of a caliper fixing bracket according to the present invention will be described with reference to the accompanying drawings.

Figure 4 is a perspective view of the caliper fixing bracket according to the present invention, Figure 5 is a plan view of the caliper fixing bracket according to the present invention, Figure 6 is a four-piston caliper mounted on the disc rotor using the bracket according to the present invention An example of use is shown.

As shown in FIGS. 4 to 6, the caliper fixing bracket 100 according to the present invention includes a first horizontal member 110 spaced apart at intervals at which the disc rotor 30 can be inserted and arranged in parallel with each other; It comprises a second horizontal member 120, and a connecting member 130 for connecting one end of the first horizontal member 110 and the second horizontal member 120.

In addition, the caliper fixing bracket 100 according to the present invention is made of a high strength aluminum alloy of duralumin-based, it is lighter than the conventional four-piston caliper fixing bracket 10 made of carbon steel, so that the weight of the parts can be realized. . As such, when the weight reduction of the parts is implemented, not only the braking performance and the acceleration performance of the vehicle are improved, but there is an advantage that fuel efficiency can be obtained. At this time, the four-piston caliper fixing bracket 100 according to the present invention undergoes a quenching process for increasing strength, a tempering process for increasing toughness, and is manufactured through a gromate treatment for forming an oxide film. Anodizing is possible, but anodizing is a simple anti-oxidation treatment, but gromate serves to harden the surface. Since the heat treatment process and the surface treatment process is a process commercialized in various industries, a detailed description thereof will be omitted.

In the first horizontal member 110, a pair of first caliper coupling holes 112 for coupling with the caliper 20 and a knuckle coupling hole 114 for coupling with the knuckle 40 are formed. In this case, the first horizontal member 110 has the other end where the knuckle coupling hole 114 is formed is refracted to extend on a surface parallel to the second horizontal member 120, and as shown in FIG. The line connecting the centers of the first caliper coupling holes 112 adjacent thereto is formed to intersect the line connecting the centers of the two first caliper coupling holes 112 at an angle of 45 degrees or less. That is, the caliper fixing bracket 100 according to the present invention may be formed at any position if the knuckle coupling hole 114 is within the 45 degree angle shown in FIG. 5, so that the user knuckles at an appropriate position according to the type of vehicle. The four cylinder caliper 20 may be fixed by forming the coupling hole 114.

The second horizontal member 120 has a pair of second caliper coupling holes 122 for coupling with another four-cylinder caliper 20, so that two four-cylinder calipers 20 are formed on the disc rotor 30. It is fastened to face each other. Accordingly, when the user presses the brake pedal, each of the four-cylinder calipers 20 generates a braking force by bringing pads (not shown) into close contact with both surfaces of the disc rotor.

At this time, the number of the first caliper coupling hole 112 and the second caliper coupling hole 122 is not limited to two as shown in this embodiment, and may be appropriately increased or decreased according to the size or characteristics of the caliper.

In addition, the connection member 130 is formed with one or more heat dissipation holes 132 for dissipating heat generated during braking, thereby preventing wear or reducing braking force due to the temperature increase of the pad and the disc rotor.

The caliper fixing bracket 100 according to the present invention is formed so that the portion where the knuckle coupling hole 114 is formed is bent and extended so as to correspond to the knuckle hole 42 of all vehicles, and thus, the caliper fixing according to the present invention When the bracket 100 is used, the four-piston caliper 20 may be mounted on the disc rotor 30 of a vehicle other than the vehicle equipped with the four-piston caliper 20 as shown in FIG. 6.

After coupling the two four-piston calipers 20 to the pair of caliper fixing brackets 100, the disc rotor 30 is positioned between the first horizontal member 110 and the second horizontal member 120. 6, one side of the first horizontal member 110 meets the knuckle hole 42. The manufacturer forms a knuckle coupling hole 114 in a portion corresponding to the knuckle hole 42, and the user combines the bracket 100 and the knuckle 40 by using a coupling means such as a bolt.

The caliper fixing bracket 100 according to the present invention may be configured to change the formation position of the knuckle coupling hole 114 according to the type of the vehicle to which the four-piston caliper 20 is to be mounted, The knuckle coupling holes 114 may be formed at respective portions corresponding to the knuckle holes 42. As such, when a plurality of knuckle coupling holes 114 are previously formed in one bracket 100, there are advantages that they can be used in common regardless of the type of vehicle to which the four-piston caliper 20 is to be mounted.

There may be two or more knuckle coupling holes as necessary, and may be formed anywhere in the bent and extended portion of the first horizontal member.
