Abstract
The invention discloses a main pump assembly for braking bicycles. The main pump assembly comprises a handle (1), a push rod (13), a main pump shell (29), an oil inlet bolt (18), a main pump piston (25) and an oil cup (23), wherein a handle adjusting bolt (5) is arranged at a position, inside the handle (1), where the handle is supported against one end of the push rod; a handle adjusting nut (3) is sleeved on the handle adjusting bolt; and the oil cup (23) is arranged in the main pump shell and is supported against the lower part of the main pump piston. By the main pump assembly disclosed by the invention, the handle adjusting nut can be rotated directly, the fit size between the handle adjusting bolt and the push rod is changed through rotating the handle adjusting bolt, different holding spans of the handle are eliminated, and the braking force and sensibility for the bicycle are improved. The oil cup is arranged in the main pump shell, so that the main pump assembly is conveniently and wholly mounted on the bicycle, the occupied space is small, and the oil cup is not easily aged and is not damaged. Therefore the quality and the braking performance of a brake are improved, and the safety of the bicycle and the product generality are greatly improved.
Description
Technical field
The present invention relates to a kind of Brake for vehicle, specifically relate to a kind of main pump assembly that is applied to bicycle brake.
Background technology
The cycle racing growth momentum is good at present, and along with people improve constantly the requirement of healthy living and environmental protection, cycle racing has become the main flow of development instantly.A safe bicycle, brake are crucial, and domestic bicycle is that skin is stopped and line is stopped mostly.Bicycle produces a large amount of heats in braking procedure, cause that very easily the brake facing temperature raises, and friction coefficient descends, cause heat fade, be that brake efficiency descends, the insensitivity variation and in braking because excess Temperature produces noise, the safety of driving reduces.
This cycle brake is the integral type cycle brake, comprises brake disc, brake clamp (namely dividing pump assembly), main pump assembly and oil pipe assembly, and its brake disc is exposed in air and high speed rotating, and radiating effect is good; Deceleration and stopping performance is stable; Brake disc is followed wheel and is rotated together, can throw away water or mud, so water is restorative better; Deceleration and stopping performance is stable, has greatly improved the safety of driving; Long service life and at when braking noiselessness, it is convenient to change; The trend of industry development is to stop with the alternative skin of disc type brake to stop with line.Its main pump assembly is directly controlled push rod and is driven the turnover that the main pump piston is realized hydraulic oil by handle, more whether passes in and out braking that minute pump assembly realizes bicycle by the oil pipe assembly.Because everyone is not quite similar to the span of holding of handle, cause indicating brake action, sensitivity on bicycle to affect to some extent; And its lubricating cup generally is contained in (comprising oil cup cap, lubricating cup pad) outside of main pump housing, the integral installation in inconvenient bicycle less space, also easily aging, be damaged.Thereby affected the overall performance of drg.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, and a kind of insensitivity main pump assembly that bicycle brake good, easy for installation is used is provided.
Purpose of the present invention realizes by following technical solution: the main pump assembly that bicycle brake is used, comprise handle, push rod, main pump housing, oil-feed bolt, main pump piston, lubricating cup, locate the handle adjusting bolt is housed in the top mutually in described handle and with an end of push rod, cover has the handle setting nut on this handle adjusting bolt; Described lubricating cup be contained in the main pump housing and with the bottom Xiang Ding of main pump piston.
After adopting structure of the present invention, can by the direct turning handle setting nut of staff, by turn handle adjusting bolt, change the fit dimension between handle adjusting bolt and push rod, eliminate handle be not quite similar hold span, improve indicating brake action, sensitivity to bicycle; The integral installation of main pump assembly on bicycle is convenient in the inside that lubricating cup is contained in the main pump housing, and it is little to take up room, and that lubricating cup is difficult for is aging, can not be damaged.Thereby improved quality and the deceleration and stopping performance of drg, greatly improved the safety of driving and product commonality (can left-right universal).
Description of drawings
The present invention is described in further detail below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the structural representation of the main pump assembly used of bicycle brake of the present invention.
The specific embodiment
With reference to Fig. 1 as can be known, the main pump assembly that bicycle brake of the present invention is used, comprise handle 1, push rod 13, main pump housing 29, oil-feed bolt 18, main pump piston 25, lubricating cup 23 (comprising oil cup cap, lubricating cup pad), locate handle adjusting bolt 5 is housed in the top mutually in described handle 1 and with an end of push rod 13, cover has handle setting nut 3 (exposing handle) on this handle adjusting bolt 5; Described lubricating cup 23 be contained in main pump housing 29 and with the bottom Xiang Ding of main pump piston 25.
Wherein, front leather cup 17, rear leather cup 28 and jump ring 15 are housed between main pump housing 29 and main pump piston 25, pull back spring 26 and pull back spring seat 27 are housed on main pump piston 25, one end of push rod 13 by handle adjustment pin 4 be contained on handle 1, its other end is connected with main pump piston 25, spindle 20, oliva 19 are housed in oil-feed bolt 18, are used for the turnover of hydraulic oil.Be equipped with to refuel in described main pump housing 29 and at the upper side place of lubricating cup 23 and stop up 21, be used for the interpolation of hydraulic oil.Handle 1 is connected by screw of handle 11 with main pump housing 29.When needing braking, point by the rider and hold and press down handle, drive push rod, main pump piston and hydraulic oil is also extruded by the oil-feed bolt from lubricating cup with this; Decontrol finger when needing brake off, release handle gets final product, main pump piston, push rod are realized return.For different riders, eliminate handle be not quite similar hold span, but the direct turning handle setting nut of staff by turn handle adjusting bolt, changes the tight ness rating between handle adjusting bolt and push rod.
