Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: a drum brake with a lubrication mechanism comprises a brake drum 1, a brake shoe 2 is arranged on the inner side of the brake drum 1, a sleeve 3 is arranged on the brake shoe 2, an installation shaft 4 is arranged on the inner side of the sleeve 3, a bag body 5 is arranged in the installation shaft 4, a driving plate 6 is arranged on the installation shaft 4, and a vertical shaft 7 is provided on the driving plate 6, a scroll spring 8 is provided between the vertical shaft 7 and the driving plate 6, and the driving plate 6 is connected with the vertical shaft 7 through the scroll spring 8, and the surface of the driving plate 6 is provided with an extrusion block 9, the lower end of the capsule body 5 is connected with a vertical pipe 10, the outer side of the vertical pipe 10 is provided with a horizontal pipe 11, and the vertical tube 10 and the horizontal tube 11 are both positioned inside the mounting shaft 4, one end of the brake shoe 2 is provided with a return spring 12, and the surface of the brake shoe 2 is provided with a wear-resistant block 13, and the wear-resistant block 13 is located inside the brake drum 1.

Brake shoe 2 passes through sleeve 3 and installation axle 4 constitution revolution mechanic, and sleeve 3 upper end extends and is provided with two platelike structures, makes things convenient for sleeve 3 when the outside of installation axle 4 rotates.

Utricule 5 is the rubber material, and utricule 5 nested install inside the upper end of installation axle 4, conveniently stably places lubricating oil.

The drive plate 6 forms revolution mechanic through vertical axis 7 and installation axle 4, and drive plate 6 and extrusion piece 9 set up as an organic whole, are favorable to drive plate 6 to carry out rotary motion on installation axle 4 through vertical axis 7, so make things convenient for drive plate 6 to drive extrusion piece 9 and carry out synchronous motion.

Standpipe 10 and violently pipe 11 intercommunication each other between, and violently pipe 11 equidistant distribution on standpipe 10 makes things convenient for lubricating oil to pass standpipe 10 and violently pipe 11 and pour into the installation axle 4 and carry out lubricated work between the sleeve 3.
