Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a brake caliper,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brake caliper for preventing leakage of brake oil to prevent brake oil from leaking to the outside of a caliper formed inside a brake caliper, and more particularly, To a brake caliper for preventing leakage of brake oil, wherein a connection port for preventing leakage of brake oil from the hydraulic line is provided between the hydraulic lines.

Generally, the brake system of a car generates friction by hydraulic pressure to decelerate or stop the vehicle while driving, so that the kinetic energy of the car is converted into heat energy and the heat energy is released to the air, There are mechanical handbrakes (parking brakes) that can be operated by rods or wires.

The hydraulic type foot brake includes a drum type brake in which the hydraulic pressure is fed to the wheel cylinder of the driving wheel so that the opposite piston in the wheel cylinder is opened to the left and right by the hydraulic pressure to press the brake lining of the brake shoe onto the brake drum, There is a disc type brake that is fed by a caliper and the piston of the cylinder in the caliper presses the brake pads against both sides of the brake disc by hydraulic pressure.

The disk type brake includes a disk connected to the driving wheel and a brake caliper mounted on the disk and having a brake pad for pressing the disk. Brake calipers have an integral type with one or more pistons on each side and a split type with one or more pistons on both sides, which are separated so as to be symmetrical in the left and right direction with respect to the disk.

The brake caliper of the split type is conventionally provided on the outside of the caliper to move hydraulic pressure for pressing the piston. However, since the hydraulic line is exposed to the outside of the caliper, the brake oil leaks to the hydraulic line due to its relatively low durability Occasionally.

In order to solve this problem, a technique of machining a hydraulic line inside a brake caliper has been developed. However, when separate calipers are combined, a hydraulic line can not be completely closed, and brake oil leaks finely when used for a long time frequently .

In order to prevent leakage of the brake oil due to such a problem, an o-ring made of a rubber material is installed between the hydraulic lines. However, since the brake oil is moved to a high temperature, the o-ring hardens, Which is not completely blocked.

Therefore, it is necessary to develop a brake caliper having improved durability in order to improve the brake caliper having the weakness in durability as described above.

1 to 3, a brake caliper for preventing brake oil leakage according to the present invention has a first caliper body 100 and a second caliper body 200.

A first oil line 110 is formed in the first caliper body 100. The first oil line 110 is formed in a hollow shape so that the brake oil can flow, and one side and the other side are exposed on one side of the first caliper body 100. This is to allow the brake oil to flow into one side and the other side of the first oil line 110.

A first piston insertion hole 101 into which the brake piston P is inserted is formed inside the first caliper body 100. The first piston insertion groove 101 communicates with the first oil line 110 So that the brake oil flows into the piston insertion groove 101. At this time, since the oil seal P-1 is formed on the outer surface of the brake piston P, the brake oil is not leaked to the outside of the first caliper body 100. Therefore, the brake piston P moves in the front-rear direction due to the hydraulic pressure of the brake oil, and can press the brake pad 600 described later.

A second oil line 210 is formed in the second caliper body 200. The second oil line 210 is hollowed in the same way as the first oil line 110, and the brake oil is transferred to the hollow interior. The second oil line 210 is also formed so that both ends thereof are exposed on one side of the second caliper body 200.

The brake piston P is inserted into the second caliper body 200. The brake piston P is inserted into the first caliper body 100 in a shape and position corresponding to the first piston insertion hole 101 formed in the first caliper body 100, A second piston insertion hole 201 to be inserted is formed. The second piston insertion hole 201 communicates with the second oil line 210, and brake oil flows into the second piston line insertion hole 201. Since the brake piston P is inserted integrally with the oil seal P-1 when the brake piston P is inserted into the second piston insertion hole 201, it is possible to prevent the brake oil from leaking to the outside of the second caliper body 200.

The first caliper body 100 and the second caliper body 200 are coupled to each other. Both sides of the first oil line 110 and the second oil line 210 are connected to each other. At this time, both side ends of the first oil line 110 and the opposite ends of the second oil line 210 are located at the same position and are in contact with each other without any error so that brake oil is supplied to the first caliper body 100 and the second caliper body 200 To be circulated.

Therefore, due to the hydraulic pressure of the brake fluid, the first caliper body 100 and the brake piston P mounted on the second caliper body 200 can simultaneously move in the front-rear direction to press the brake pad 600 described later .

Referring to FIG. 1, an oil inlet 300 is formed on the other side of the second caliper body 200. The oil inlet 300 is for supplying the brake oil from the outside to the first oil line 110 and the second oil line 210. Thus, the oil inlet 300 communicates with the second oil line 210.

Referring to FIGS. 1 and 4, a leakage preventing connection 400 is provided between the first oil line 110 and the second oil line 210. The leakage preventing connection member 400 may include a first oil line 110 and a second oil line 210 to prevent leakage of brake oil between the first oil line 110 and the second oil line 210, Lt; / RTI > That is, even if both ends of the first oil line 110 and the second oil line 210 are in contact with each other in a precise contact, the first caliper body 100 and the second caliper body 200 It is possible to prevent the brake oil from leaking into a gap generated by the deformed outer shape of the brake fluid.

2 and 5, first seating grooves 120 having diameters greater than the diameter of the first oil line 110 are formed at both ends of the first oil line 110, respectively. The first seating groove 120 has a shape embedded in the first caliper body 100 at a predetermined depth. One side of the leak-proof connector (400) is inserted into the first seating groove (120).

At both ends of the second oil line 210, a second seating groove 220 having a diameter larger than the diameter of the second oil line 210 and having a shape corresponding to the first seating groove 120 is formed. The second seating groove 220 also has a shape that is embedded in the first caliper body 100 at a certain depth so that the other side of the leakage preventing connector 400 can be inserted and seated

Referring to FIG. 6, the leakage preventing connector 400 includes a through hole 410 through which brake oil can pass, a leakage preventing connection 400, a first caliper body 100, It is preferable that the first and second caliper bodies 200 and 200 have a hardness different from that of the first and second caliper bodies 100 and 200.

Referring to FIG. 6, a first seat 121 is formed between the first seat 120 and the first oil line 110, and a first seat 121 is formed at one side of the leakage preventing connector 400 Respectively. A second seating jaw 221 is formed between the second seating groove 220 and the second oil line 210 and is symmetrical to the first seating jaw 121. The second seating jaw 221 is provided with a leakage And the other side end of the preventing coupling hole 400 is contacted to prevent leakage of the brake oil.

That is, when the first caliper body 100 and the second caliper body 200 are coupled by the fastening bolt or the like, one end of the leakage preventing connector 400 is pressed against the first seat 121, And is brought into contact with the second seating surface 221 by pressing. At this time, when the first caliper body 100 and the second caliper body 200 are closely contacted with each other by increasing the engagement torque for coupling the first caliper body 100 and the second caliper body 200, The first seating step 121 presses the first seating step 121 and the first seating step 121 is deformed. That is, since the hardness of the leakage preventing connection portion 400 is higher than that of the first caliper body 100, the first seating portion 121 is crushed by the coupling torque, so that the one end of the leakage preventing connection portion 400 and the first seating portion 121 So that the leakage of the brake oil can be prevented and the first oil line 110 and the second oil line 210 are communicated with each other through the through hole 410 so that the brake oil can circulate .

The other end of the leakage preventing connection member 400 and the second mounting jaw 221 exhibit the same operational effects as the connection structure of the one end of the leakage preventing connection member 400 and the first mounting jaw 121, do.

5, a description will be made of another embodiment of the tightening relationship between the leakage preventing connection member 400 and the first caliper body 100 and the second caliper body 200. The first seating groove 120 and the first oil line A first seating surface 121 is formed between the first seating surface 110 and the first seating surface 121. The first seating surface 121 is formed to be inclined at a predetermined angle. A second seating groove 221 is formed between the second seating groove 220 and the second oil line 210 so that the second seating groove 221 is inclined at the same angle as the first seating groove 121 .

The leak-proof connector 400 includes a through-hole 410 having a diameter smaller than that of the first oil line 110 and the second oil line 210 so that the brake oil can pass therethrough. At this time, the leakage preventing connection port 400 is inclined such that one end 401 is an acute angle smaller than the inclination angle of the first seating jaw 121, and the other end is also smaller than the inclination angle of the second seating jaw 221 It tilts. Since the one end 401 and the other end of the leakage preventing connector 400 are formed at different angles with respect to the first and second seatings 121 and 221, It becomes.

Since the one end 401 of the leakage preventing connector 400 has an acute angle, when it is inserted into the first seating groove 120, it is in line contact with the end E of the first seating jaw 121, 410). ≪ / RTI > At this time, when the engagement torque for coupling the first caliper body 100 and the second caliper body 200 is increased, the sealing force of the first seating step 121 and the one end 401 of the leakage preventing connection part 400 is further improved .

The other end of the leakage preventing connector 400 is symmetrical with the one end 401 of the leakage preventing connector 400 and has the same effect as the operation effect, and thus a detailed description thereof will be omitted.

5 and 6, a first fixing groove 122 is formed at one side of the first mounting groove 120 along the edge of the first mounting groove 120, A second fixing groove 222 is formed along the edge of the second mounting groove 220.

At this time, the insertion protrusion 420 protrudes outward from the side surface of the leakage preventing connector 400 on the side of the leakage preventing connector 400. One side and the other side of the protruding insertion protrusion 420 are slidably fitted in the first fixing groove 122 and the second fixing groove 222. The leakage preventing connection member 400 is detached from the first and second seating grooves 120 and 220 by the impact generated when the first caliper body 100 and the second caliper body 200 are engaged It is possible to prevent the occurrence of the leakage phenomenon and to prevent the leakage of the brake oil by preventing the gap between the leakage preventing connector 400 and the first caliper body 100 and the second caliper body 200 have.

Referring to FIG. 7, an elastic member 500 is provided between the piston P and the first caliper body 100 or the second caliper body 200. The elastic member 500 may be formed of a coil-shaped spring. The pressing force can be uniformly transmitted to the brake pads 600 when the piston P presses the brake pads 600 due to the provision of the elastic members 500 and the piston pushed by the elastic force of the elastic members 500 (P) can be easily restored to the initial position. When the diameter of the coil constituting the elastic member 500 is gradually increased, when the piston P moves backward, it is prevented that the coils are brought into contact with each other, thereby restricting the backward movement of the piston P There is an advantage that it can be prevented.
