Disc brakes are also known as butterfly brakes, which are controlled by hydraulic pressure. The main components include brake discs, brake calipers, cylinders, oil pipes, etc. The brake discs are made of alloy steel and fixed on the wheels. The wheels turn. Due to the advantages of fast heat dissipation, light weight, simple structure, especially high temperature resistance and stable braking effect under high load, disc brakes are currently widely used in cars. Among them, the brake caliper is the carrier used to install the piston and the oil pipe. However, the existing disc brakes are relatively rough when braking, so the requirements for the brake pipelines are relatively high, and because the existing pistons The area is small, the consumption is large, and the required brake hydraulic pressure is also high. Therefore, a servo device is required to actuate the pressure of the pipeline during braking, which leads to an increase in the overall cost and low use efficiency. Therefore, it is necessary to The existing brake is improved, but the original brake caliper structure as a carrier can no longer meet the demand, so a brake caliper body structure with better performance is required.

Preferably, a stopper is provided on one side of the upper part of the body, and the stopper is an arc-shaped structure. The function of the stopper is to match the shape of the brake disc, so that the brake disc can rotate normally without exceeding the control range of the brake caliper. the

Optimally, reinforcing ribs are respectively connected between the two lugs and the main body. The utility model can enhance the connection strength between the piston installation holes on both sides and the body by setting the reinforcing ribs, even when it is stretched by a relatively large external force, it can still maintain the structural stability of the entire device, which also improves the brake caliper. Stretch resistance. the

Optimally, a square locking groove is further provided above the annular boss, the number of the square locking grooves is four and they are distributed at 90° to each other, and the depth of the square locking grooves is 2-3 mm. The oil pipe can be fixed by setting the square slot. During installation, a flange is usually set on the upper end of the oil pipe. After the flange is matched with the square slot, the oil pipe can be radially limited to prevent It rotates with the brake disc, thereby protecting the oil pipe. the

Optimally, a chamfer is also provided at the bottom of the axle. Here, the installation position of the brake caliper can be optimized by setting the chamfer to avoid friction and collision with the components on the wheel, and it is also more convenient to install.

Compared with the prior art, the utility model has the following beneficial effects:

1. Two pistons can be installed: The brake caliper of the present utility model has installation holes for installing the pistons at both ends, so that two pistons can be installed at the same time, which can increase the friction force and is also conducive to The wear of a single piston is reduced and the braking efficiency is improved.

2. It can meet the demand of high brake hydraulic pressure without the assistance of an additional servo device, so the structure is more simplified, more practical, and the cost is also significantly reduced.

3. Easy installation, good structural strength and long service life.
