Description

Technical Field

[0001] The utility model relates to the technical field of brake pad steel backs, and specifically relates to a brake pad steel back convenient for installation. Background Technique

[0002] When the vehicle brakes, the brake fluid transmits pressure to the brake caliper through the brake pipe, causing the brake caliper to clamp the brake pad. When the brake pad contacts the wheel, due to the heat generated by friction, a high-pressure area is formed between the brake pad and the brake steel back. This high-pressure area tightly adheres the brake pad and the brake steel back together, thus forming an integral body, enhancing the load-bearing capacity of the brake pad. At the same time, the heat conduction performance of the brake pad steel back can quickly transfer the generated heat to the wheel and dissipate the heat quickly through heat dissipation, thereby ensuring the safety and reliability of the braking system.

[0003] When installing the existing brake pad steel back, since the installation of the brake pad steel back requires manual positioning by hand, it is not convenient to quickly limit the position of the brake pad steel back for installation, and this method affects the work efficiency.

[0004] Patent document CN105299100A discloses a brake pad steel back, "including a plate body with a steel back structure formed by stamping a steel plate. Grooves arranged in a matrix along its shearing direction are stamped on the front surface of the plate body. The longitudinal section of the groove is trapezoidal, the bottom area of the groove is 0.8 - 2.4 mm2, the opening angle of the groove is 15 - 25°, the depth of the groove is 0.8 - 1.2 mm, and the spacing between the grooves is 1 - 4 mm; an irregular sunken platform is stamped at the center position of the front surface of the plate body, and at least one buckle surface perpendicular to the plate body is arranged on the sunken platform in the direction perpendicular to the shearing direction of the plate body, and the depth of the sunken platform is 1.5 - 2.5 mm". However, the above-mentioned brake pad steel back in the disclosed document mainly considers simple production processes and low production costs; it increases the contact area between the plate body and the adhesive, is firm and durable, sensitive, and can provide the braking safety of the vehicle, but does not consider the problem that the brake pad steel back is not convenient for installation. Therefore, it is necessary to research and develop a device convenient for installing the brake pad steel back. Content of the Utility Model

[0005] The purpose of the utility model is to provide a brake pad steel back convenient for installation, so as to solve the technical problem of inconvenient quick limit fixation during the installation of the brake pad steel back proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] Compared with the prior art, the beneficial effects of the present utility model are as follows: A brake pad steel back that is convenient to install, including a steel back body and a suction cup body. The suction cup body is embedded inside the steel back body. A nut is fixedly installed on the suction cup body.

[0009] Preferably, rivet holes are provided on both sides inside the steel back body.

[0010] Preferably, a suction cup body is installed on the side of the exhaust hole and the rivet hole.

[0011] 1. By installing a vacuum suction cup, the present utility model facilitates improving the working efficiency of installing the brake pad steel back. When installing the brake pad steel back, make one side of the suction cup body fit the installation location, rotate the threaded rod, and the position of the threaded rod will move through the cooperation of the nut. When the threaded rod moves, it will drive the bearing to move. The outer ring of the bearing is fixedly connected to the center position of the rubber sheet, and thus the middle position of the rubber sheet will be sunken inward to form negative pressure, and then the steel back body will be temporarily limited at the installation location. When fixedly installing the steel back body, there is no need to manually hold it to limit its position for installation, which improves the installation efficiency.
