Embodiment Construction

[0009] Such as figure 1 As shown, the present invention proposes a brake, including a brake disc 1 fixed to the hub and a brake caliper 2 fixed to the axle. The brake caliper 2 includes an oil chamber 3, an oil inlet 4 and 1 The piston port 5 on the side, the piston port 5 is sleeved with a piston 6, and the piston sleeve 8 is arranged between the piston 6 and the piston port 5. It communicates with the oil chamber 3 or the lubricating assembly.

[0010] A brake proposed by the present invention uses a hydraulic method to push the piston 6 to the rotating brake disc 1 to achieve the purpose of braking. The lubricating port 7 formed or communicated with the oil chamber 3 can store oil during use to ensure the lubrication between the piston 6 and the piston sleeve 8, effectively prolonging the service life of the piston 6.

[0011] Preferably, the number of moistening ports 7 is four.

[0012] Further, the 4 lubricating ports 7 are evenly distributed on the mating surface of ...

Abstract

The invention provides a brake. The brake comprises a brake disc used for being fixed to a hub and a brake caliper fixed to an axle. The brake caliper comprises an oil cavity, an oil inlet and a piston opening facing the side face of the brake disc. A piston is sleeved with the piston opening. A piston sleeve is arranged between the piston and the piston opening. A lubricant opening is formed in the matching surface of the piston sleeve and the piston. The lubricant opening is communicated with the oil cavity or a lubrication assembly. According to the brake, the piston is pushed to the rotating brake disc surface in a hydraulic mode, so that the braking purpose is achieved; meanwhile, the lubricant opening communicated with the lubrication assembly or the oil cavity is formed in the piston sleeve between the piston and the piston opening, thus, oil can be stored in the using process, lubrication between the piston and the piston sleeve is guaranteed, and the service life of the piston is prolonged effectively.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a brake. Background technique [0002] For a long time, the heat dissipation design of the brake is defective, resulting in a short service life. Contents of the invention [0003] The object of the present invention is to provide a brake that solves one or more of the above-mentioned problems in the prior art. [0004] The invention proposes a brake, including a brake disc fixed on the wheel hub and a brake caliper fixed on the axle. The brake caliper includes an oil chamber, an oil inlet and a piston port facing the side of the brake disc. The inner sleeve of the piston port A piston is provided, a piston sleeve is arranged between the piston and the piston port, and a lubricating port is opened on the mating surface of the piston sleeve and the piston, and the lubricating port communicates with the oil chamber or the lubricating assembly. [0005] A brake proposed by the present inv...
