Description

Technical Field

[0001] The utility model relates to the technical field of brake pads, in particular to a brake pad installation component. Background Art

[0002] The brake pads are connected to the caliper in the brake device in a limiting manner. The left and right oppositely arranged brake pads approach each other to achieve frictional braking on the tire or its linkage structure. If the external thrusts of the left and right brake pads are uneven or the brake track deforms after long-term use, the brake pads will tilt or cannot be displaced stably, resulting in unnecessary contact and friction between the brake pads and the brake disc, or reducing the braking effect and causing unnecessary wear of the brake pads, shortening the service life of the brake pads and generating noise during use. To solve such problems, the applicant previously developed a brake spring plate (CN212250910U), which includes a back plate and leg assemblies symmetrically arranged on both sides of the back plate. The leg assembly includes a middle leg and clamping legs symmetrically arranged on both sides of the middle leg. The middle leg and the clamping legs are bent towards the same side of the back plate, and an arc-shaped bending part protruding towards the bending direction of the middle leg is provided at a position near the end of the middle leg. The distance between the end of the clamping leg and the back plate is greater than the distance between the arc-shaped bending part of the middle leg and the back plate; mounting holes are provided at the junction of the back plate and each middle leg and at the junction of the back plate and each clamping leg. This brake spring plate enables accurate installation and positioning of the brake pads, not only ensuring that the brake pads are completely separated from the brake disc when returning, avoiding unnecessary wear of the brake pads to extend the service life of the brake pads, but also greatly reducing brake noise.

[0003] To further improve the stability of the positioning and displacement of the brake pads, the applicant has improved the design of the installation component for installing the brake pads. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the disadvantages and deficiencies existing in the prior art, and provide a brake pad installation component. The technical solution adopted by the utility model is as follows:

[0005] A brake pad installation component includes a track plate, on which a brake track is integrally provided. The brake track includes limiting plates located at the left and right ends of the track plate. A guiding travel groove is opened on the limiting plate. A protruding installation part is provided on the side of the brake pad back plate, and a positioning protrusion extending into the guiding travel groove is provided on the installation part. The limiting plates are connected to the left and right ends of the track plate through side baffles, and a supporting plate is correspondingly arranged below the limiting plates. A brake track for accommodating the installation part of the brake pad back plate is formed between the limiting plates, the side baffles and the supporting plate.

[0006] Preferably, the side baffle is bent forward at the outer end of the track piece, and the limiting plate is connected to the upper end of the side baffle and extends inward.

[0008] Preferably, a connection fixing part is arranged at the outer end of the lower plate of the substrate for fixing the track piece.

[0009] Preferably, the two brake tracks on the track piece are symmetrically distributed left and right. The left and right ends of the lower plate of the substrate respectively have hollow parts. The lower plate of the substrate is integrally connected to an elastic sheet extending into the hollow parts. The elastic sheet is connected to a guide plate. The guide plate is bent upward relative to the elastic sheet so that the guide plate is located above the lower plate of the substrate and the included angle between the guide plate and the lower plate of the substrate is an acute angle; when the installation part of the brake pad back plate is installed in the brake track, the guide plate contacts and guides the side of the brake pad to ensure the stable displacement of the brake pad.

[0010] Preferably, there is a notch between the left and right ends of the lower plate of the substrate, and the notch extends to the lower end or middle part of the vertically arranged track piece.

[0011] Preferably, the installation part of the brake pad back plate is bent relative to the brake pad, and the positioning protrusion is arranged in a hemispherical shape on the upper surface of the installation part of the brake pad back plate.

[0012] The beneficial effects of the present utility model are as follows: The brake pad installation assembly forms a brake track through the combination of the limiting plate, the side baffle and the supporting plate for the limiting installation and sliding of the installation part of the brake pad back plate; a guiding stroke groove is opened on the limiting plate, and a positioning protrusion extending into the guiding stroke groove is arranged on the installation part of the brake pad back plate, so that the brake pad is more stable during the displacement process.

The limit plate 11 is connected to the left and right ends of the orbital plate 1 through side baffles 12. A supporting plate 13 is correspondingly provided at the lower position of the limit plate 11. A brake track for accommodating the mounting part of the back plate 41 of the brake pad is formed between the limit plate 11, the side baffle 12 and the supporting plate 13.

[0021] The side baffle 12 is bent forward at the outer end of the orbital plate 1, and the limit plate 11 is connected to the upper end of the side baffle 12 and extends inward; referring to the attached Figure 1 , the "outer" here refers to the directions at both ends of the orbital plate and the directions of continuous extension at both ends, and the "inward" refers to the direction opposite to the outward direction. For example, the limit plate 11 is connected to the inner side position of the upper end of the side baffle 12.

[0024] The two braking tracks on the track piece 1 are symmetrically distributed left and right. Both the left and right ends of the lower substrate plate 2 have hollowed-out parts. The elastic pieces 21 integrally connected and extending into the hollowed-out parts are provided on the lower substrate plate 2. The elastic pieces 21 are connected to the guide plates 23.
