TECHNICAL FIELD

[0001] The utility model relates to brake caliper technical field, concretely is a kind of wear-resistant floating brake caliper. BACKGROUND

[0002] Floating brake caliper is a kind of common automobile brake system assembly, mainly used in disc brake. Its design makes brake caliper can be relatively floating when applying braking force, to improve braking effect and uniformity, floating brake caliper, also known as sliding caliper, is a kind of common caliper type, its main feature is that its brake caliper is floating, specifically, floating brake caliper can freely slide on the shaft pin matched with support, when braking, piston extends, inner brake pad first contacts brake disc, then brake caliper floats inward, outer brake pad also contacts brake disc, to generate braking torque;

[0003] If floating brake caliper cannot be buffered and protected during use and wear, it cannot effectively apply uniform braking force, resulting in weakened braking effect, increased braking distance, and the contact between worn brake caliper and brake disc may produce abnormal sound, if brake caliper cannot normally float, it can cause more serious wear on one side of brake pad, causing uneven wear, further affecting braking effect, and brake pad may need to be replaced more frequently, worn brake caliper can cause uneven contact between brake pad and brake disc, further causing excessive wear, deformation or scratching of brake disc.

[0004] Therefore, a wear-resistant floating brake caliper is proposed. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a wear-resistant floating brake caliper to solve the problems raised in the above background.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a wear-resistant floating brake caliper, comprising a shell, a piston is inserted and connected in the middle of both sides of the shell, an installation support is fixedly connected to the outer wall of the piston on both sides, a heat sink is fixedly connected to the top of the installation support, a pair of round holes are formed in the inner wall of the shell on both sides, a brake ring is fixedly connected to the inner wall of the round hole on both sides, a plurality of semispherical protrusions are fixedly connected to the inner wall of the brake ring on both sides, and a protective sheet is fixedly connected to the outer wall of the shell on both sides.

[0007] Preferably, guide pins are arranged in the middle of both ends of the shell.

[0008] Preferably, locking nuts are threadedly connected to the outer wall of both ends of the guide pin on both sides, and a baffle is slidingly connected to the outer wall of both ends of the guide pin on both sides.

[0009] Preferably, connecting springs are fitted at both ends of the outer wall of the guide pins on both sides.

[0010] Preferably, one end of the connecting spring is fixedly connected to the baffle, and the other end of the connecting spring is fixedly connected to the outer casing.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By installing a protective plate on the outer wall of the brake caliper housing for initial protection, and then installing brake rings and hemispherical protrusions on both sides of the inner wall, the friction force experienced by the entire brake caliper during braking can be increased, ensuring that the vehicle wheel hub can stop rotating stably, reducing multiple rotational contacts between the housing and the wheel hub, and thus reducing the friction experienced by the housing. The protective plate can effectively reduce the direct contact between the brake caliper housing and the wheel hub, reduce friction and wear, thereby extending the service life of the brake caliper and the wheel hub and reducing maintenance costs;

[0013] 2. By setting flexible contact buffer mechanisms on both sides of the housing, the housing can be buffered and protected when subjected to impact forces. When an external object collides with the housing, the flexible contact buffer mechanism can absorb and disperse the impact force, thereby protecting the housing from damage and reducing the damage to the housing caused by the collision. The flexible contact buffer mechanism helps to extend the service life of the housing, which means that the equipment can maintain its appearance and functional integrity for a longer period of time, thereby reducing maintenance and replacement costs.

Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0021] Please refer to Figs. 1 to 4 An embodiment provided by the present application is as follows: a wear-resistant floating brake caliper, comprising a shell 1, a piston 4 is inserted and connected at the middle part of the two sides of the shell 1, an installation support 2 is fixedly connected to the outer wall of the two pistons 4, a heat dissipation plate 3 is fixedly connected to the top of the installation support 2, a pair of round holes are formed in the inner walls of the two sides of the shell 1, a brake ring 5 is fixedly connected to the inner walls of the two round holes, a plurality of semispherical protrusions 6 are fixedly connected to the inner walls of the two brake rings 5, and a protective sheet 7 is fixedly connected to the outer walls of the two sides of the shell 1.

[0024] The middle part of the two ends of the shell 1 is provided with a guide pin 8, the outer wall of the two ends of the two guide pins 8 is threadedly connected with a locking nut 9, the outer wall of the two ends of the two guide pins 8 is slidably connected with a baffle 10, the outer wall of the two ends of the two guide pins 8 is sleeved with a connecting spring 11, one end of the connecting spring 11 is fixedly connected with the baffle 10, and the other end of the connecting spring 11 is fixedly connected with the shell 1.

[0026] Better: when the shell 1 is subjected to impact force, it can be protected on both sides, and the deformation of the extrusion connecting spring 11 makes the outer wall of the shell 1 contact with the baffle 10.

The heat sink 3 can absorb and disperse the heat generated by friction during the operation of the brake caliper, ensuring the temperature balance of the brake caliper as a whole. The setting of the hemispherical protrusion 6 inside the brake ring 5 can increase the efficiency during the brake deceleration process, avoiding severe wear caused by continuous brake deceleration of the shell 1, reducing the repeated contact between the shell 1 and the hub, and thereby reducing the friction on the shell 1. The setting of the protective sheet 7 can effectively reduce the direct contact between the brake caliper shell 1 and the hub, reduce friction and wear, thereby prolonging the service life of the brake caliper and the hub, and reducing maintenance costs. When the shell 1 is subjected to impact force, it can be protected on both sides, and the deformation of the extrusion connecting spring 11 makes the outer wall of the shell 1 contact with the baffle 10.
