The cylinder body is installed in the fixed frame and can move relative to the fixed frame. The piston fits in the cylinder body and can move relative to the cylinder The body moves, the inner end of the piston fits in the cylinder body, the outer end of the piston is fixed with the inner brake pad assembly, the cylinder body is designed as a bayonet-shaped structure, and a cylinder liner is arranged on one side of the bayonet, and the piston fits in the In the cylinder liner, the other side of the bayonet is fixed to the outer brake pad assembly. When the driver steps on the brake pedal, the oil chamber of the cylinder liner of the cylinder body generates oil pressure and pushes the piston to move outward. The outer end of the piston is connected with the inner brake pad assembly, and the piston moves to the outside of the cylinder liner. Push the inner brake pad assembly to press the brake disc. At the same time, the oil pressure generated by the oil chamber of the cylinder liner of the cylinder is also applied in the opposite direction of the piston movement. Pushed by the oil pressure, the cylinder moves in the opposite direction of the piston movement. Moving, the outer brake pad assembly fixed on the other side of the bayonet of the cylinder body is also pressed against the brake disc to form a braking effect on the brake disc. Fig. 1 is a schematic structural view of a brake pad assembly of a brake caliper in the prior art, and Fig. 2 is a side view of a brake pad assembly of a brake caliper in the prior art, the brake pad assembly includes a shim 1', The peripheral shape of the spacer 1' coincides with the peripheral shape of the brake pad. Since the caliper vibrates simultaneously with the vehicle during braking, when the vibration frequency of the caliper is similar to that of the vehicle disc and steering knuckle, the caliper is prone to resonance and Ultimately, abnormal noise is caused, which affects the comfort of driving.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a brake caliper with an improved structure of the brake pad gap filler. By improving the structure of the brake pad gap filler, the brake pad can be effectively changed during the braking process. The vibration frequency can effectively avoid the abnormal noise caused by the similar braking frequency, thus improving the driving comfort.

The technical solution adopted by the utility model to solve the technical problem is: a brake caliper with an improved structure of the brake pad filler, including a brake pad assembly; the brake pad assembly includes a brake pad and a gap filler; the brake pad and The shims are stacked and matched; when the brake pads and the shims are stacked, one end of the shim has a shape corresponding to one end of the brake pad, and the other end of the shim is fitted on the brake pad. The middle position, and the other end of the spacer is arc-shaped.

The other end edge of the spacer is in the shape of a semicircle.

The other end edge of the said spacer is in the shape of a semi-ellipse.

The other end of the spacer is arranged at a position corresponding to the middle of the brake pad and biased toward the other end of the brake pad.

The other end of the spacer is arranged at a middle position corresponding to the middle of the brake pad to the other end of the brake pad.

The shims are stainless steel shims.

The utility model relates to a brake caliper with an improved structure of the brake pad shim, which improves the structure of the brake pad shim so that the edge of the other end of the brake pad does not correspond to the other end of the brake pad. It forms an irregular shape, and the area where the spacer and the brake pad fit together is smaller than the brake pad, which can effectively change the vibration frequency of the brake pad during the braking process.

The beneficial effect of the utility model is that: when the brake pad and the shim are superimposed, the shim is designed such that one end thereof has a shape corresponding to one end of the brake pad, and the other end fits in the The middle position of the brake pad, and the other end of the spacer is arc-shaped. With this structure, the other end of the spacer is in a non-fitting shape relative to the other end of the brake pad, which can effectively change the vibration frequency of the brake pad during the braking process and effectively avoid abnormal vibrations caused by similar braking frequencies. Noise is generated, thereby improving driving comfort.

The utility model will be described in further detail below in conjunction with the accompanying drawings and embodiments; however, the brake caliper with improved structure of the brake pad shim of the utility model is not limited to the embodiments.
