Description

Technical Field

[0001] This utility model relates to the field of brake caliper technology, and in particular to a lightweight floating brake caliper. Background Technology

[0002] Brake calipers are components that apply force to brake discs. They are caliper devices that decelerate, stop, or maintain a stopped state of the moving wheels. Based on whether the brake caliper is movable, they can be divided into floating calipers and fixed calipers. Floating brake calipers are brake calipers that can float, sliding freely on a pivot pin that mates with the caliper bracket. The brake caliper primarily receives hydraulic pressure from the master cylinder through the brake lines, which is then applied to the piston inside the caliper. During braking, the piston extends, and the inner friction pads first contact the brake disc. Then, the caliper floats inward, and the outer friction pads also contact the brake disc. The friction between the inner and outer friction pads generates friction, causing the vehicle to decelerate. The vehicle's kinetic energy is converted into frictional heat and dissipated into the atmosphere.

[0003] Currently, conventional brake pads are connected to the caliper bracket by fixing them to the left and right sides. This connection method requires cutting mounting grooves on both sides of the caliper bracket's inner wall for the mounting lugs on both sides of the brake pads. This occupies space on both sides of the caliper bracket, increasing its width and weight, which is detrimental to lightweight brake caliper design. Furthermore, the way the brake pads are connected to the inner walls of the caliper bracket means that when the brake pads are under stress, the force is transmitted from the stress points on both sides to the inner walls of the caliper bracket. Over time, and during hard braking, the stress on the sides of the caliper bracket can lead to deformation, resulting in reduced braking performance. Utility Model Content

[0004] To address the technical problems of existing technologies, such as the connection method between the friction pad and the caliper bracket increasing the width and weight of the caliper bracket, which is detrimental to the lightweight design of the brake caliper, and the stress on both sides of the caliper bracket causing the caliper bracket to deform, this utility model provides the following technical solution.

[0005] This utility model discloses a lightweight floating brake caliper, comprising a fixed bracket with an outer brake arm and two fixed arms, and a piston assembly connected to the fixed bracket. The fixed arms are fixedly connected to a sliding pin, and the sliding pin is slidably connected to a caliper bracket. A telescopic sleeve with both ends connected to the fixed arms and the caliper bracket is sleeved around the outer periphery of the sliding pin. The caliper bracket includes an outer bracket with an outer friction plate connected to its bottom and an inner bracket with an inner friction plate connected to its bottom. At least one side of the inner wall of the outer bracket and at least one side of the inner wall of the inner bracket are provided with a plurality of spring grooves, and a support spring connected to the outer friction plate and the inner friction plate is provided in the spring groove.

[0006] As a further technical solution, both the outer bracket and the inner bracket are provided with mounting grooves at their bottoms, and connectors are installed in the mounting grooves. The connectors are respectively connected to the outer friction plate and the inner friction plate.

[0007] As a further technical solution, a return spring is connected to the adjacent ends of both the outer friction plate and the inner friction plate.

[0008] As a further technical solution, two longitudinally distributed spring grooves are provided on one side of the inner wall of the outer support and one side of the inner wall of the inner support, and the spring grooves are fixedly connected to the support spring.

[0009] As a further technical solution, the telescopic sleeve is a telescopic dustproof corrugated pipe structure.

[0010] As a further technical solution, the outer support and the inner support are integrally formed.

[0011] The beneficial effects of this invention are as follows: The inner and outer friction plates are respectively installed in the bottom mounting slots of the inner and outer brackets via connectors, reducing the number of cutting grooves at the friction plate mounting points. This allows for a suitable reduction in the overall width of the caliper bracket, optimizing its weight and facilitating lightweight brake caliper design. Simultaneously, the change in the force-bearing position of the inner and outer friction plates on the caliper bracket optimizes the lever arm at the force-bearing points, reducing the risk of caliper bracket deformation and ensuring braking performance. Furthermore, a support spring connected to the inner sidewall of the caliper bracket connects and supports the inner and outer friction plates. The support spring and return spring ensure safe rebound of the inner and outer friction plates, guaranteeing timely disengagement from the brake disc when the brake is released, preventing caliper jamming.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0019] In the description of this utility model, it should be understood that the terms "upper" and "lower" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0020] like Figure 1 As shown, this utility model discloses a lightweight floating brake caliper, which includes a fixed bracket 1 with an outer brake arm 101 and two fixed arms 102. The fixed bracket 1 is connected to a piston assembly 2. The fixed bracket 1 and the piston assembly 2 adopt existing technology, so their specific structure and connection method will not be described in detail.

[0021] like Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, both fixed arms 102 are fixedly connected to sliding pins 4 by bolts. A caliper bracket 3 is axially slidably connected to the sliding pins 4. The caliper bracket 3 can float axially relative to the sliding pins 4, moving closer to or further away from the piston assembly 2. At this time, a telescopic sleeve 5 is fitted around the outer periphery of the sliding pins 4. The telescopic sleeve 5 is a telescopic dustproof corrugated pipe structure, with its two ends connected to the fixed arms 102 and the caliper bracket 3, respectively.

[0022] In a preferred embodiment, the caliper bracket 3 includes an outer bracket 301 and an inner bracket 302, both of which are inverted U-shaped structures. The outer bracket 301 and the inner bracket 302 are integrally formed, and the upper ends of the caliper bracket 3 are slidably connected to two sliding pins 4 on both sides. An outer friction plate 7 is connected to the bottom of the outer bracket 301, and an inner friction plate 8 is connected to the bottom of the inner bracket 302. The brake disc is located between the outer friction plate 7 and the inner friction plate 8. When the outer friction plate 7 and the inner friction plate 8 move relative to each other, they will generate friction on the brake disc, which facilitates the deceleration or stopping of the vehicle.

[0023] At this point, both the bottom of the outer bracket 301 and the bottom of the inner bracket 302 are provided with mounting grooves 303. Connectors 6 are installed within the mounting grooves 303. Connectors 6 are of existing structure and are connected to the outer friction plate 7 and the inner friction plate 8, respectively. This connection method reduces the number of cutting grooves at the mounting locations of the inner friction plate 8 and the outer friction plate 7, allowing for a suitable reduction in the overall width of the caliper bracket 3 and optimizing its weight, thus facilitating a lightweight design for the entire brake caliper.

[0024] like Figure 2 and Figure 5 As shown, in a preferred embodiment, at least one side of the inner wall of the outer bracket 301 and at least one side of the inner wall of the inner bracket 302 are provided with a plurality of spring grooves 304. Support springs 9, connected to the outer friction plate 7 and the inner friction plate 8, are provided within the spring grooves 304. In this embodiment, two longitudinally distributed spring grooves 304 are provided on one side of the inner wall of the outer bracket 301 and one side of the inner wall of the inner bracket 302. The spring grooves 304 are fixedly connected to the support springs 9. Simultaneously, return springs 10 are connected to the adjacent ends of the outer friction plate 7 and the inner friction plate 8. The support springs 9 can connect and support the inner friction plate 8 and the outer friction plate 7. Therefore, the support springs 9 and the return springs 10 can safely rebound the inner friction plate 8 and the outer friction plate 7, ensuring that the inner friction plate 8 and the outer friction plate 7 can disengage from the brake disc in a timely manner when the brake is released, preventing the caliper from jamming.

[0025] When this utility model is working, the piston assembly 2 moves the inner friction plate 8 towards the brake disc via hydraulic drive, and at the same time the caliper bracket 3 floats axially. At this time, the outer brake arm 101 pushes the outer friction plate 7 towards the brake disc, and the outer friction plate 7 and the inner friction plate 8 rub against the brake disc to decelerate and brake.

[0026] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, various changes or equivalent substitutions can be made without departing from the concept of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
