Abstract
The utility model discloses a main pump assembly for braking a bicycle. The main pump assembly for braking the bicycle comprises a handle (1), a pushing rod (13), a main pump shell body (29), an oil inlet bolt (18), a main pump piston (25) and an oil cup (23). A handle adjusting bolt (5) is arranged at the position, abutted against one end of the pushing rod, inside the handle (1), a handle adjusting nut (3) is sleeved on the handle adjusting bolt, and the oil cup (23) is installed in the main pump shell body and abutted against the lower portion of the main pump piston. According to the main pump assembly, the handle adjusting nut can be directly rotated, the matching size between the handle adjusting bolt and the pushing rod can be changed by rotating the handle adjusting bolt, the different gripping span of the handle can be removed, and braking force and flexibility on the bicycle are improved. The oil cup is installed inside the main pump shell body so as to facilitate the whole arrangement of the main pump assembly on the bicycle, occupied space is small, and the oil cup is not easy to age and can not be damaged. Therefore, quality of a brake and braking performance of the brake are improved, and safety and product universality of bicycle driving 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 healthy living and environmental protection requirement, 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, insensitivity variation and in braking, produce noise, traveling security reduction owing to temperature is too high.
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 the 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 improved traveling security greatly; 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 driven the turnover that the main pump piston is realized hydraulic oil by handle control push rod, whether pass in and out braking that the branch pump assembly realizes bicycle by the oil pipe assembly again.Because everyone is not quite similar to the span of holding of handle, causes braking dynamics, the sensitivity of bicycle are influenced to some extent; And its lubricating cup generally is contained in (comprising oil cup cap, lubricating cup pad) outside of main pump housing, and the integral installation in the less space of inconvenient bicycle is also easily worn out, is damaged.Thereby influenced the overall performance of drg.
Summary of the invention
The objective 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, in described handle and with an end of push rod, locate to be equipped with handle adjusting bolt in the top mutually, regulate bolt at this handle and be with the handle setting nut; Described lubricating cup is contained in the main pump housing and with the main pump lower part of piston and pushes up mutually.
After adopting structure of the present invention, can regulate bolt by the turn handle by the direct turning handle setting nut of staff, change the fit dimension between handle adjusting bolt and the push rod, eliminate handle be not quite similar hold span, improve braking dynamics, 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 lubricating cup is difficult for wearing out, can not being damaged.Thereby improved quality and the deceleration and stopping performance of drg, improved traveling security and product commonality (can the left and right sides general) greatly.
Description of drawings
The present invention is described in further detail below in conjunction with accompanying drawing and embodiment.
The structural representation of the main pump assembly that Fig. 1 uses for 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), in described handle 1 and with an end of push rod 13, locate to be equipped with handle adjusting bolt 5 in the top mutually, regulate bolt 5 at this handle and be with handle setting nut 3 (exposing handle); Described lubricating cup 23 be contained in the main pump housing 29 and with the bottom Xiang Ding of main pump piston 25.
Wherein, leather cup 17, back leather cup 28 and jump ring 15 before being equipped with between main pump housing 29 and the main pump piston 25, pull back spring 26 and pull back spring seat 27 are housed on the main pump piston 25, one end of push rod 13 regulates by handle that pin 4 is contained on the handle 1, its other end links to each other with main pump piston 25, spindle 20, oliva 19 are housed in the oil-feed bolt 18, are used for the turnover of hydraulic oil.In described main pump housing 29 and at the upper side place of lubricating cup 23, be equipped with to refuel and stop up 21, be used for the interpolation of hydraulic oil.Handle 1 links to each other by screw of handle 11 with main pump housing 29.When needing braking, hold and press down handle by rider's finger, with this drive push rod, main pump piston and with hydraulic oil from lubricating cup and extrude by the oil-feed bolt; Then 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 is regulated bolt by the turn handle, changes handle and regulates tight ness rating between bolt and the push rod.
