Problems solved by technology

Currently commonly used hydraulic disc brakes are prone to the following deficiencies due to the design structure and manufacturing reasons: First, since most hydraulic disc brakes adopt an open self-compensating structure, the clearance of the friction plate of the lower pump is relatively small, and adjustment during use tougher
The second is that the oil cylinder of the lower pump of many hydraulic disc brakes returns slowly, which will affect the feel of the upper pump

Embodiment Construction

[0013] The present invention will be further described below in conjunction with implementation.

[0014] figure 1 It is a three-dimensional exploded view of a specific embodiment of the bicycle unilateral hydraulic disc brake lower pump of the present invention, combined with figure 2 , image 3 and Figure 4 Explain as follows: main formation of the present invention is tongs body 1, sealing ring 2, oil cylinder 3, heat-insulating jack post 4, left magnet 5, stage clip 6, small pliers body 9, right magnet 10 and adjusting screw 11. The large pliers body 1 has a cylinder hole to accommodate the oil cylinder 3, and the outer edge of the cylinder hole has a groove to accommodate the compression spring 6; the compression spring 6 is made of steel sheet or steel wire, and its elastic force presses the oil cylinder 3 and heat insulation in static state. The top column 4 and the compression spring 6 are fixed on the tong body 1 by screws or the compression spring 6 is fixed on ...

Abstract

The invention discloses a bicycle single-side oil pressure disc brake lower pump which comprises a large tong body (1), a heat insulation top column (4), a compressed spring (6), a small tong body (9)and an adjusting screw (11). A groove for containing the compressed spring (6) is arranged on the outer edge of an oil cylinder hole in the large tong body (1); elastic force of the compressed spring(6) presses the oil cylinder (3) and the heat insulation top column (4) when the compressed spring is in the static state, and the compressed spring (6) is fixed to the large tong body (1); the adjusting screw (11) is installed in the middle of the small tong body (9). When in use, a gap of a friction plate is convenient and easy to adjust, the touch of an upper pump is improved due to the effectof the compressed spring (6), and meanwhile replacement convenience of the friction plate is not affected.

Description

technical field [0001] The invention relates to a hydraulic disc brake used in bicycles, electric power-assisted bicycles and motorcycles, referred to as a hydraulic disc brake for short. Background technique [0002] Bicycles, electric power-assisted bicycles and motorcycles widely use hydraulic disc brakes, and hydraulic disc brakes are an essential part of these vehicles. Currently commonly used hydraulic disc brakes are prone to the following deficiencies due to the design structure and manufacturing reasons: First, since most hydraulic disc brakes adopt an open self-compensating structure, the clearance of the friction plate of the lower pump is relatively small, and adjustment during use raletively hard. Second, the recovery of the oil cylinder of the lower pump of many hydraulic disc brakes is relatively slow, which will affect the feel of the upper pump. Contents of the invention [0003] In view of the defects of the above-mentioned existing technologies, the pu...
