Description

Disc brake calipers

technical field

The utility model relates to a disc brake caliper, in particular to a disc brake caliper which can be easily assembled on a vehicle.

Background technique

Generally speaking, a brake system is usually composed of at least a brake master cylinder, a brake oil pipe, a brake caliper and a brake disc. The brake oil pipe is connected between the brake master cylinder and the brake caliper, and brake oil is contained in the brake oil pipe. When it is desired to perform a braking operation on the brake disc, the brake master cylinder will build up oil pressure, and transmit the oil pressure to the brake calipers through the brake oil pipe, so that the brake calipers can generate braking force to resist the rotation of the brake disc.

Please refer to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a conventional disc brake caliper 1 mainly includes a caliper cylinder 11, a fixed frame 12, an inner brake pad 13, an outer brake pad 14, a first A fixing pin 15 and a second fixing pin 16 .

The caliper cylinder 11 has an oil injection hole 11a, an oil chamber 11b, a piston 11c, a body portion 11d and a support portion 11e. The oil injection hole 11a is connected to the oil chamber 11b, and a brake oil pipe (not shown) can be connected between the oil injection hole 11a and a brake master cylinder (not shown). The piston 11c is movably provided in the oil chamber 11b. The body part 11d is located above the oil chamber 11b and the support part 11e, and the body part 11d is connected between the oil chamber 11b and the support part 11e. The support portion 11e is opposed to the oil chamber 11b. In addition, there is an opening 11f between the body portion 11d, the oil chamber 11b and the support portion 11e, which can be used to accommodate a brake disc (not shown).

The fixing frame 12 is connected to the caliper cylinder 11 and can be used to fix the caliper cylinder 11 on a front fork of a motorcycle. In more detail, the fixed frame 12 is connected to the body part 11d of the caliper cylinder 11, and the fixed frame 12 surrounds the opening 11f through the bottom of the body part 11d, that is, the opening 11f is located between the fixed frame 12 and the body part. between 11d. In addition, the fixing frame 12 has a positioning surface 12a and a plurality of locking holes 12b. The positioning surface 12a is used to abut against and fix the inner brake pad 13, and the fixing frame 12 can be fixed on the front fork of the motorcycle through bolts (not shown) and locking holes 12b.

The inner brake pad 13 is disposed in the opening 11f of the caliper cylinder 11, and the inner brake pad 13 is connected to the piston 11c.

The outer brake pad 14 is also disposed in the opening 11 f of the caliper cylinder 11 , and the outer brake pad 14 is adjacent to the supporting portion 11 e of the caliper cylinder 11 . In addition, the outer brake pads 14 are spaced apart from the inner brake pads 13 at a certain distance, and a brake disc (not shown) is disposed between the outer brake pads 14 and the inner brake pads 13 .

The first fixed pin 15 and the second fixed pin 16 are opposite to each other, and the first fixed pin 15 and the second fixed pin 16 are simultaneously installed in the caliper cylinder 11, the fixed frame 12 and the outer brake pad 14, so that the The caliper cylinder 11, the fixing frame 12 and the outer brake pad 14 are fixed together.

When the brake disc is to be braked, the oil pressure established by a brake master cylinder will be transmitted to the oil chamber 11b of the caliper cylinder 11 through a brake oil pipe (not shown) and the oil injection hole 11a to push the piston 11c . At this time, the piston 11c will push the inner brake pad 13, so that the inner brake pad 13 and the outer brake pad 14 clamp the brake disc located therebetween, thereby achieving a braking effect.

However, the conventional disc brake caliper 1 has the following disadvantages. Since the fixing bracket 12 surrounds the opening 11f through the bottom of the body portion 11d (that is, the opening 11f is located between the fixing bracket 12 and the body portion 11d), the assembly between the fixing bracket 12 and the front fork of the motorcycle will be very inconvenient. . More specifically, the assembly space between the fixing frame 12 surrounding the opening 11f and the front fork of the motorcycle through the lower part of the main body 11d is often insufficient, thus resulting in the inability to fix the disc brake caliper 1 on the front fork of the motorcycle. , or the configuration of the brake disc must be greatly changed to cooperate with fixing the disc brake caliper 1 on the front fork of the motorcycle.
