Description

Disc brake calipers

technical field

The utility model relates to a disc brake caliper, in particular to a disc brake caliper which can avoid vibration and noise.

Background technique

Please refer to Figure 1, Figure 2, Figure 3 and Figure 4, a known disc brake caliper 1 mainly includes a fixed frame 10, a caliper cylinder 20, a first yoke spring 30, a second yoke spring 40 . A first brake shoe 50 and a second brake shoe 60 .

As shown in FIG. 3 , the fixing frame 10 has a first accommodating slot 11 and a second accommodating slot 12 . The first accommodating groove 11 is opposite to the second accommodating groove 12 .

As shown in FIG. 1 , FIG. 2 , FIG. 3 and FIG. 4 , the caliper cylinder 20 is connected to the fixing frame 10 . In more detail, a first fixing pin 70 and a second fixing pin 80 pass through the caliper cylinder 20 and the fixing frame 10 to combine the caliper cylinder 20 and the fixing frame 10 together.

Still as shown in FIG. 3 , the first yoke spring 30 is disposed in the first accommodating groove 11 of the fixing frame 10 , and the second yoke spring 40 is disposed in the second accommodating groove 12 of the fixing frame 10 .

As shown in Figure 1, Figure 3 and Figure 4, the first brake shoe 50 is arranged in the caliper cylinder 20, and the first brake shoe 50 is directly supported by the first yoke spring 30 and the second yoke spring 40. Clamping, so that the first brake shoe 50 can be fixed in the fixing frame 10 .

As shown in FIGS. 1 and 4 , the second brake shoe 60 is also arranged in the caliper cylinder 20 , and the second brake shoe 60 is also directly clamped by the first yoke spring 30 and the second yoke spring 40 . In this way, the second brake shoe 60 can be fixed in the fixing frame 10 . In addition, the second brake shoe 60 is opposite to the first brake shoe 50 , and a brake disc (not shown) is disposed between the first brake shoe 50 and the second brake shoe 60 .

When the disc brake caliper 1 is used for braking operation, the brake hydraulic pressure will be established inside the caliper cylinder 20 to force the first brake shoe 50 and the second brake shoe 60 to move towards each other, thus clamping the rotating brake disc disc, which in turn can force the vehicle to slow down or stop.

However, the disc brake caliper 1 has a disadvantage in operation. Since the first brake shoe 50 and the second brake shoe 60 are usually made of soft metal material, and the whole disc brake caliper 1 is often in a state of high vibration, so the first yoke spring 30 and the second brake shoe The two yoke springs 40 will rub against the first brake shoe 50 and the second brake shoe 60, thus causing the first brake shoe 50 and the second brake shoe 60 to be pressed by the first yoke spring 30 and the second yoke spring. Wear occurs at the place where 40 is clamped. Therefore, the first brake shoe 50 and the second brake shoe 60 will loosen from the first yoke spring 30 and the second yoke spring 40 . As mentioned above, during the running of the vehicle, the loose first brake shoe 50 and the second brake shoe 60 will collide with the caliper cylinder 20 and the brake disc due to vibration and generate noise.
