Description

Technical Field

[0002] At present, the outer shell of a vehicle brake is integrally cast, then the internal brake cavity is machined, and then the brake components are installed.

[0003] Among them, the pressure arm mechanism and the rotating ball are integrally placed into the brake cavity from the action side of the brake structure of the brake cavity shell, and then the brake reference seat and the brake components are installed.

[0004] An arc - shaped bearing structure is installed between the reference seat and the pressure arm, and this bearing structure needs to be closely fitted. The traditional bearing structure is respectively fitted with the outer arcs of the reference seat and the pressure arm. However, when it is placed from the hole side of the brake structure of the brake cavity, the bearing structure is very easy to deviate from the outer arc surface of the pressure arm. When the bearing is inverted and installed during actual assembly, it will fall off. This requires manual repeated adjustment of the position before the reference seat can be installed continuously, resulting in low installation efficiency. Repeated adjustment will also cause collisions between components, resulting in wear and bumps, affecting the rotation accuracy and service life of the rotation.

[0005] If the bearing structure is designed to be in an integral state with the reference seat or the pressure arm during installation, the installation efficiency can be effectively improved. Summary of the Invention

[0017] The following further describes the specific content of the present invention: The brake pressure arm rotating bearing device of the present invention with an anti - detachment mechanism solves the problem that the bearing structure between the pressure arm and the reference seat is prone to falling off and shifting during split installation.

[0018] The brake is of a casting structure. One side is a brake cavity, and the other side is a brake pad mounting bracket. The connection position between the brake pad mounting bracket and the brake cavity is the mounting hole of the braking mechanism. When installing this device, rotating balls, a pressure arm reference seat, and a brake rotating component are successively placed through this mounting hole.

[0019] The bearing housing 5 is arc - shaped. The inner side mounts the ball bearing 6. The ball bearing 6 includes a ball positioning part and cylindrical balls. The ball positioning part is arc - shaped, with a groove on the inner arc surface for installing the cylindrical balls, and the outer surface is embedded in the bearing housing 5.

[0020] The arc - shaped inner side of the bearing housing 5 is grooved for installing the ball bearing 6, and relief grooves are provided on both sides of the groove. The bearing housing 5 is provided with positioning plates 9 on both sides of the positioning enough and bent towards the pressure arm 7 to prevent the ball bearing 6 from slipping out.

[0021] The pressure arm 7 is Y - shaped, with a brake shaft in the middle and rotating arms on both sides. The outer surface of the rotation center of the rotating arms is a smooth surface that contacts the ball bearing 6.

[0022] In the present device, the reference seat and the bearing housing 5 are of an integrated installation structure. Specifically, a positioning hook 1 extending towards the reference seat 2 is provided on the side. The reference seat 2 is provided with a positioning hole 3. The positioning hook 1 is inserted into the positioning hole 3 through a positioning sleeve 4. The positioning sleeve 4 is made of plastic, with ribs 41 provided on all four sides and a hole in the middle for embedding the positioning hook 1.

[0023] The positioning sleeve 4 of the present device is cylindrical with one end open, and the hole is a rhombic hole. The cross - section of the positioning hook 1 is rhombic, and the positioning hook 1 is inserted into the rhombic hole of the positioning sleeve 4 with an interference fit.

[0024] Specifically, the edge of the positioning hook 1 on the bearing housing 5 where it is installed is on the swinging side of the pressure arm 7, and the positioning hook 1 is perpendicular to the swinging center of the pressure arm 7.

[0025] The bearing sleeve 4 of the present device is made of plastic, with ribs 41 provided on all four sides, which can be closely fitted with the hole on the base. The plastic material will not cause structural wear during press - fitting installation.

[0026] The rhombic hole 42 in the middle of the bearing sleeve 4 matches the cross - section shape of the positioning hook (1), so that the semi - circular bearing of the bearing housing is inserted into the rhombic hole (3) on the bearing sleeve 4 through the rhombic positioning hook (1), enabling the bearing sleeve (4) and the ball bearing (6) to be closely fitted to form a whole.

[0027] During installation, first install the rotating ball, pressure arm, bearing bracket and reference seat, and then other components. When placing the bearing bracket and reference seat, due to their integral structure, installers can hold the rear part of the reference seat and align it with the outer arc surface of the pressure arm, and then fit the structure of the ball bearing and the bearing bracket, effectively achieving precise docking and avoiding sliding errors or even collisions caused by the partial arc section of the ball bearing structure, thus effectively improving the installation correct rate.

[0028] Designing the reference seat and bearing structure as an integral installation can avoid the problems of slow installation speed of the bearing structure when installed separately, and easy collision, bumping and wear caused by dropping; it can improve the installation speed of the brake and the consistency quality of the product.
