Description

Technical Field

[0001] The utility model relates to the technical field of automobile braking systems, in particular to an electric vehicle caliper. Background Art

[0002] As a key component in the automobile braking system, the performance of electric vehicle calipers directly affects the safety and stability of vehicle driving. Traditional electric vehicle calipers are usually assembled from multiple independent components, such as caliper body, piston assembly, guide mechanism and brake pads, and the guide mechanism often uses a combination of guide rods and return springs. These components are combined together through complex connections, which not only increases the manufacturing cost, but also due to the large number of components and complex assembly, it is easy to loosen or wear, affecting the stability and reliability of the braking effect.

[0003] Therefore, how to design an electric vehicle caliper with a simpler structure, fewer components, and stable and reliable braking effect has become an urgent problem to be solved. Utility Model Content

[0004] In view of the deficiencies in the background technology, the utility model provides an electric vehicle caliper.

[0005] The technical solution adopted by the utility model is: an electric vehicle caliper, comprising:

[0006] A caliper body, wherein a piston housing is integrally formed at one end of the caliper body, a raised limiting step is provided at the other end of the caliper body, a movable space is formed between the limiting step and the piston housing, and a driving assembly is provided in the piston housing;

[0007] A guide bracket, wherein the guide bracket is fixedly connected to the caliper body, and a front slide groove and a rear slide groove are arranged on both sides of the guide bracket;

[0008] The brake pad comprises a front brake pad and a rear brake pad, wherein the front brake pad is located in an activity space close to the side of the limiting step and slidingly cooperates with the front slide groove, and the rear brake pad is located in an activity space away from the side of the limiting step and slidingly cooperates with the rear slide groove, and the rear brake pad can move to the side of the front brake pad under the action of the driving component.

[0009] Furthermore, there are two limit steps, and a fitting plane connected to the front brake pad is provided on the limit step.

[0010] Furthermore, a slag removal and heat dissipation groove is provided on the caliper body below the activity space.

[0011] Furthermore, the front brake pad and the rear brake pad are provided with a straight groove.

[0012] Furthermore, the guide bracket includes an arch frame and connecting guide blocks located at both ends of the arch frame, and the front slide groove and the rear slide groove are arranged on the connecting guide blocks.

[0013] Furthermore, connecting heads are provided at both ends of the caliper body, connecting heads are provided with connecting holes, and the connecting guide block is connected to the connecting heads by bolts.

[0014] Furthermore, fixing holes are provided at both ends of the arch frame.

[0015] Furthermore, both ends of the front brake pad and the rear automatic pad have notches for slidingly matching with the front slide groove and the rear slide groove.

[0016] The beneficial effects of the utility model are:

[0017] 1. Simplified structure and improved efficiency: This application mainly includes the caliper body, piston housing, drive assembly, guide bracket and brake pad. The original guide rod and return spring and other components are discarded, and a slide groove is directly set on the caliper body to guide the sliding of the brake pad, which greatly reduces the number of components of the electric vehicle caliper and simplifies the overall structure. This not only reduces production costs, but also reduces the assembly complexity and potential failure points caused by too many components, and improves production efficiency and product quality.

[0018] 2. Enhanced rigidity and improved stability: The one-piece piston housing at one end of the caliper body and the limit step at the other end work together to form a stable support structure, which enhances the rigidity of the entire electric vehicle caliper. In addition, the drive assembly is directly integrated into the caliper body to further reduce the number of parts and assembly difficulty. At the same time, this design enables the electric vehicle caliper to maintain structural stability when subjected to high-intensity braking pressure, avoiding the reduction in braking effect caused by loose connections or deformation between components in traditional electric vehicle calipers.

[0019] 3. Optimize the guide mechanism to ensure braking accuracy: By setting the front and rear slides on the guide bracket, precise guide paths are provided for the front and rear brake pads. This double slide design ensures that the brake pads can move smoothly along the predetermined trajectory when acted upon by the drive assembly, effectively preventing the brake pads from deflecting, improving the accuracy and response speed during braking, and thus ensuring the stability and reliability of the braking effect.

[0020] In addition to the objects, features and advantages described above, the present invention has other objects, features and advantages.
