A brake caliper component with a friction plate spring return structure

Abstract

This utility model relates to a brake caliper component with a friction pad spring return structure, belonging to the field of brake components in the automotive braking technology field. A spring is installed between two friction pads. Two bolts pass through the spring and the two friction pads respectively, connecting the spring and the two friction pads to the caliper body. The spring and the two friction pads move along the axial direction of the bolts. The advantages are its novel structure; by adding a spring as a return structure to the traditional caliper, it provides limiting, support, and return functions for the friction pads, optimizing the return mechanism and ensuring timely reset. This avoids continuous friction between the friction pads and the brake disc, reducing wear and heat generation. Simultaneously, it prevents abnormal wear and noise, extends the service life of the braking system, significantly improves product reliability and durability, enhances vehicle safety, and meets the automotive braking system's requirements for high performance, long lifespan, and low maintenance costs.

Description

Technical Field

[0001] This utility model belongs to the field of automotive braking technology and relates to brake components, specifically a brake caliper component with a friction pad and spring return structure. Background Technology

[0002] The automotive braking system is a crucial component of vehicle safety, directly impacting driving safety and stability. With continuous advancements in automotive technology, braking system technology is constantly being upgraded and improved. The brake is the most critical component of the braking system, generating braking torque through friction with the wheels to decelerate or stop the vehicle. Traditional brake calipers often fail to fully disengage from the brake disc after brake release, resulting in continuous contact between the brake pads and disc during driving. This generates drag, increases energy consumption, and reduces vehicle efficiency. Summary of the Invention

[0003] This invention provides a brake caliper component with a friction pad spring return structure to solve the problem that the friction pad cannot return to its original position in time after the brake is released, resulting in continuous friction with the brake disc, increased wear, heat generation, and reduced service life of the brake system.

[0004] The technical solution adopted by this utility model is as follows: it includes a clamp body, friction plates, bolts and spring plates, wherein the spring plate is installed between two friction plates, and two bolts pass through the spring plate and the two friction plates respectively to install the spring plate and the two friction plates to the clamp body, and the spring plate and the two friction plates move along the axial direction of the bolts.

[0005] The bolts are internal hex bolts.

[0006] The spring plate includes two cards connected at the top, with two positioning holes at the top connection. The two cards are respectively engaged with the outer edges of the two friction plates, which spring the friction plates on both sides apart and make them fit against the brake caliper body.

[0007] The two cards have an outward elastic force.

[0008] The advantages of this invention are its novel structure. A spring plate is added to the traditional caliper as a return mechanism, which limits, supports, and returns the friction pads. It is assembled to the brake caliper body with hexagonal bolts, ensuring a secure and stable connection that is less prone to loosening or detachment. When braking is applied, hydraulic pressure pushes the piston and friction pads to clamp the brake disc, applying the brakes. When releasing the brakes, the pressure-releasing piston returns to its original position, and the spring plate actively pushes the friction pads away from the brake disc, assisting in return and reducing drag. This return mechanism solves the problems of poor return, residual contact between the brake disc and brake pads, and friction issues inherent in traditional structures. The optimized return mechanism of the friction pads ensures timely reset, preventing continuous friction between the friction pads and brake disc, reducing wear, minimizing residual drag between the brake disc and brake pads, reducing drag effect, lowering energy consumption, reducing heat generation, and improving brake energy recovery efficiency. It also prevents abnormal wear and noise, extends the service life of the braking system, significantly improves product reliability and durability, enhances vehicle safety, and meets the demands of automotive braking systems for high performance, long lifespan, and low maintenance costs.

Detailed Implementation

[0011] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0012] like Figure 1 , 2As shown, it includes a clamp body 1, friction plates 2, bolts 3 and spring plates 4, wherein the spring plate 4 is installed between the two friction plates 2, and the spring plate 4 and the two friction plates 2 are respectively installed to the clamp body 1 by passing through the two bolts 3 through the spring plate 4 and the two friction plates 2, and the spring plate 4 and the two friction plates 2 move along the axial direction of the bolts 3.

[0013] like Figure 2 As shown, bolt 3 is an internal hex bolt.

[0014] like Figure 3 As shown, the spring plate 4 includes two cards 401 connected at the top, and two positioning holes 402 at the top connection. The two cards 401 are respectively engaged with the outer edges of the two friction plates 2, so as to spring the friction plates 2 on both sides apart and abut against the brake caliper body 1.

[0015] like Figure 3 As shown, the two cards 401 have an outward elastic force.

[0016] Working principle: After the piston, dust cover and other parts are installed into the brake caliper body, take two friction pads 2 and one spring pad 4, and clip the clips on both sides of the spring pad onto the outer edge of the friction pad. Put the assembled components into the brake caliper body together, insert two hexagonal bolts 3 into the caliper body, and simultaneously insert them into the positioning holes of the two friction pads and the spring pad. Finally, lock them with the caliper body. The elastic force of the clips 401 on both sides of the spring pad can reliably make the friction pad adhere tightly to the caliper body. When braking is applied, hydraulic pressure pushes the piston and friction pad 2 to clamp the brake disc and apply the brakes. When the brakes are released, the pressure relief piston returns to its original position, and the spring 4 actively pushes the friction pad 2 away from the brake disc, assisting in its return and reducing drag. The added spring 4 not only ensures the stability of the friction pad connection but also allows it to return to its original position in a timely manner, reducing drag and preventing abnormal wear and noise from components, thus reducing energy consumption.

However, the scope of protection of the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, any equivalent substitutions or modifications made by those skilled in the art based on the technical solution and the inventive concept of the present invention within the scope of the technical concept disclosed in the present invention shall all fall within the scope of protection of the present invention.
