Description

Technical Field

[0001] The utility model relates to the technical field of brake calipers, in particular to a split parking brake caliper with high safety performance. Background Art

[0002] A split parking brake caliper is a component of a braking system used to stop and keep a vehicle stationary. Compared to an integral parking brake caliper, a split parking brake caliper consists of multiple independent components, such as the brake piston, brake cover, and brake pads. These components can be replaced and repaired individually. A split parking brake caliper usually uses a hydraulic principle to apply pressure to bring the brake pads into contact with the brake disc, thereby achieving the braking function.

[0003] During use, the split parking brake caliper consists of two parts: the caliper body and the piston. The connection is prone to loosening or wear. If the brake piston is aged or damaged, it may cause hydraulic oil leakage, thus affecting the normal operation of the brake system. Due to improper installation or aging of components, the brake pads may wear unevenly, resulting in a noisy abnormal noise, affecting the braking effect and making it impossible to guarantee the safe driving performance of the vehicle.

[0004] Therefore, a split parking brake caliper with high safety performance is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a split parking brake caliper with high safety performance to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a split parking brake caliper with high safety performance, comprising a brake bracket, wherein the middle parts of both sides of the brake bracket are threadedly connected with guide pins, and the outer walls of the guide pins on both sides are slidably connected with brake pads, and the outer walls of the guide pins on both sides are located on the side of the brake pad on one side and are sleeved with rubber pads, the middle part of the brake bracket is clamped with a brake caliper housing, and the ends of the guide pins on both sides away from the brake bracket are threadedly connected to the middle part of the brake caliper housing, the middle parts of both sides of the brake bracket are threadedly connected with brake bolts, and the outer wall of the brake bracket is fixedly connected with a brake cover.

[0007] Preferably, a brake piston is fixedly connected to the middle portion of the brake cover, and a special-shaped frame is rotatably connected to the middle portion of the outer wall of the brake cover.

[0008] Preferably, a second catch piece is fixedly connected to the lower portion of the outer wall of the brake cover, and a first catch piece is fixedly connected to one end of the special-shaped frame close to the second catch piece.

[0009] Preferably, a notch is provided in the middle of the first catch member, and a spring is provided on the outer wall of the brake cover.

[0010] Preferably, one end of the spring is fixedly connected to the special-shaped frame, and the other end of the spring is fixedly connected to the second catch member.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] By providing a guide pin between the brake caliper housing and the brake bracket, the rubber pad can be easily inserted between the brake bracket and the brake pad. As the brake caliper operates, the brake pad contacts the brake disc, generating braking force through friction. Over time, the inner brake pad will suffer from wear and fatigue. The provision of the rubber pad can buffer and protect it. By squeezing the rubber pad to cause it to deform, the inner brake pad can obtain flexible contact during operation. Compared with direct contact, this greatly reduces the possibility of loosening or wear at the connection, thereby extending the service life of the entire parking brake caliper and ensuring the safe operation of the vehicle during the operation of the parking brake caliper.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 5 , an embodiment of the present invention provides: a split parking brake caliper with high safety performance, including a brake bracket 2, the middle part of both sides of the brake bracket 2 is threadedly connected with a guide pin 3, the outer walls of the guide pins 3 on both sides are slidably connected with brake pads 6, the outer walls of the guide pins 3 on both sides are located next to the brake pad 6 on one side and are sleeved with rubber pads 10, the middle part of the brake bracket 2 is clamped with a brake caliper housing 1, the ends of the guide pins 3 on both sides away from the brake bracket 2 are threadedly connected to the middle part of the brake caliper housing 1, the middle part of both sides of the brake bracket 2 is threadedly connected with a brake bolt 4, the outer wall of the brake bracket 2 is fixedly connected to a brake cover 5, and the middle part of the brake cover 5 is fixedly connected to a brake piston 8;

[0022] Among them: the brake caliper housing 1, the brake bracket 2 and the brake cover 5 are connected to the brake bolt 4 through the guide pin 3;

[0023] Better: When the split brake caliper is subjected to braking force applied by the system, hydraulic oil will be pumped into the brake caliper, pushing the brake piston 8 to move outward. As the piston moves, the brake pad 6 contacts the brake caliper housing 1. The setting of the guide pin 3 can provide a limiting guide for the adjustment movement of the brake pad 6. The setting of the brake cover 5 serves as a transition connection for the connection between the brake piston 8 and the brake bracket 2, providing necessary structural support for the entire brake caliper, ensuring that each component can be correctly aligned and remain stable, preventing deformation or loosening during operation, and helping the brake piston 8 to maintain good guidance during movement, ensuring that the piston can move smoothly and avoid sticking.

[0024] The middle part of the outer wall of the brake cover 5 is rotatably connected to the special-shaped frame 7, and the lower part of the outer wall of the brake cover 5 is fixedly connected to the second catcher 13. The end of the special-shaped frame 7 close to the second catcher 13 is fixedly connected to the first catcher 11. The middle part of the first catcher 11 is provided with a notch 12. The outer wall of the brake cover 5 is provided with a spring 9, one end of the spring 9 is fixedly connected to the special-shaped frame 7, and the other end of the spring 9 is fixedly connected to the second catcher 13.

[0025] Wherein: the special-shaped frame 7 is set to a hook shape that is staggered with the brake cover 5;

[0026] Better: During the operation of the split parking brake caliper as a whole, as the brake piston 8 is adjusted, the special-shaped frame 7 can rotate to a certain angle, so that the first grabbing piece 11 can be attached to the outer wall of the automobile wheel hub, and with the connection and cooperation of the spring 9, the adjustment process of the special-shaped frame 7 can be further made more stable. Correspondingly, the second grabbing piece 13 can also be attached to the automobile wheel hub, thereby forming a stabilizing mechanism similar to a triangular shape, ensuring that the parking brake caliper can operate stably, reducing the wear of the brake pad 6, and thus extending the overall service life of the parking brake caliper.

[0027] The above implementation works as follows:

[0028] The steps for running the job are as follows:

[0029] First, when the split brake caliper is subjected to the braking force applied by the system, the hydraulic oil (in the hydraulic system) will be pumped into the interior of the brake caliper housing 1, pushing the brake piston 8 to move outward. As the brake piston 8 moves, the brake pad 6 contacts the brake caliper housing 1. The setting of the guide pin 3 can provide a limiting guide for the adjustment and movement of the brake pad 6. The setting of the brake cover 5 plays a transitional role in the connection between the brake piston 8 and the brake bracket 2, providing the necessary structural support for the entire brake caliper, ensuring that each component can be correctly aligned and maintained stable, preventing deformation or loosening during operation, and helping the brake piston 8 to maintain good guidance during movement, ensuring that the piston can move smoothly and avoid sticking.

[0030] During the operation of the parking brake caliper, as the brake piston 8 is adjusted, the special-shaped frame 7 can rotate to a certain angle, so that the first grabbing piece 11 can be attached to the outer wall of the automobile wheel hub, and with the connection and cooperation of the spring 9, the adjustment process of the special-shaped frame 7 can be further made more stable. Correspondingly, the second grabbing piece 13 can also be attached to the automobile wheel hub, thereby forming a stabilizing mechanism similar to a triangular shape, ensuring that the parking brake caliper can operate stably, reducing the wear of the brake pad 6, thereby extending the overall service life of the parking brake caliper, reducing the occurrence of loosening or wear at the connection, extending the overall service life of the parking brake caliper, and ensuring the safe operation of the vehicle during the operation of the parking brake caliper.
