本発明はデイスクブレーキのキヤリパブラケツ
トに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a caliper bracket for a disc brake.
三・四輪バギー車では、タイヤ径が大の割りに

In three- and four-wheeled buggy vehicles, the wheel diameter is small compared to the large tire diameter, so if the disc brake is placed inside the wheel like in a normal vehicle, the brake disc becomes small in diameter, making it difficult to adjust the settings. It is difficult to secure an effective radius of the brake disc in order to obtain braking force, and since the wheels swing a lot during driving, it is desirable to reduce the unsprung weight, so it is desirable to reduce the unsprung weight. A so-called center brake device is often used.

デイスク軸方向に移動可能に支持している。 In addition, in the conventional general disc brake, as shown in Fig. 1, a caliper bracket 1 fixed to the vehicle body has an action part and a reaction part, which are a pair of pad pressing parts arranged oppositely on both sides of a brake disc 2. A caliper 3, in which the brake disc 2 is connected at a bridge part that straddles the brake disc 2, is supported so as to be movable in the disc axial direction via sliding pins 4, 4.

る。 This caliper bracket 1 is arranged on one side of the brake disc 2 and is inserted into mounting holes 1a, 1a formed in the vehicle body mounting part at a position inward in the disc radial direction from the outer edge of the brake disc 2. It is fixed to a part of the vehicle body, such as a knuckle, by bolt means, and the caliper 3 is attached via sliding pins 4, 4 at a position in the disk radial direction at the outer edge of the brake disk 2 on one side of the brake disk 2. The braking torque generated during braking is transmitted to the caliper bracket 1 via the friction pad 5, caliper 3, and sliding pin 4.
ところが、キヤリブラケツト１は、ブレーキデ
イスク２の一側面側のデイスク半径方向内方位置
で、車体に固定されていると共にキヤリパ３を片
持ち保持しているので、制動トルクによりキヤパ
リブラケツト１にねじりモーメントが生じ、摩擦
パツトの偏摩耗が生じ易くなる。 However, since the caliper bracket 1 is fixed to the vehicle body at a radially inward position on one side of the brake disc 2 and holds the caliper 3 in a cantilevered manner, the caliper bracket 1 is twisted by braking torque. A moment is generated, which tends to cause uneven wear of the friction parts.
このため、キヤリパブラケツト１を肉厚に形成

メントに耐え得るようにしているが、その分キヤ
リパブラケツト１が大型化し重量も増加して、製
作費が嵩むと共に、バネ下重量が増える。
For this reason, the carrier pub bracket 1 is made thick to give it rigidity so that it can withstand the torsional moment caused by the braking torque, but this increases the size and weight of the carrier pub bracket 1, which increases the manufacturing cost. As it becomes bulkier, the unsprung weight increases.

半径方向内方位置での車体取付がより困難とな
る。 Therefore, if the thickly formed carrier pub bracket 1 is used in the center brake device, the mounting space at the inner position in the disk radial direction is limited, so it is difficult to install the carrier pub bracket 1. Moreover, in the center brake system, the brake disc 2 rotates at a higher speed than in a system in which the brake disc is placed inside the wheel, so the carrier pub bracket 1 that receives the braking torque is required to have high rigidity. One side of the disk 2 is thicker, making it more difficult to attach the disk to the vehicle body at a radially inward position.

The purpose is to provide caliper brackets for disc brakes.
