Description
Technical field
The utility model provides a kind of bicycle brake device, particularly relates to a kind of cylinder type brake gear, belongs to technical field of bicycles.
Background technology
Bicycle is conventional industries, there is the history of more than 100 year, due to the problem of environmental protection and traffic, bicycle become once again at present countries in the world particularly developed country resident like traffic, fitness tool, the center of gravity of world's bicycle trade just from traditional type of riding instead of walk vehicle to sports type, mountain, leisure type change, in U.S., Europe, Deng developed country, bicycle is a kind of more general motion, body-building, leisure and recreational product.In the mechanical mechanism of bicycle, brake equipment-brake can be described as unit of paramount importance, because its direct relation the life security of cyclist.Bicycle develops into so far, common brake kind probably can be divided into following several: 1, binder, and this series products acts on rim, is braked by the friction between brake rubber block and rim, according to the difference of its structure, binder can be divided into that V stops, C stops at present and hang to be stopped.2, disc brake, this series products by installing the disc brake sheet rotated with axle on flower-drum, and by realizing the braking of wheel to the braking of disc brake sheet, this series products is broadly divided into line dish and oily dish two class at present.3, brake holding, this series products by installing annular brake rubber block on flower-drum, and when braking, brake rubber block tightens up and directly acts on flower-drum, to reach the object of braking.
At present along with the development of bicycle competitive sport, drivers require more and more higher for bicycle weight-saving.People seek various mode to alleviate the weight of bicycle, and at present in the lightweight for brake gear is studied, research direction is mainly started with from material aspect, makes every effort to reach weight-saving requirement from material.But the requirement of the safety performance due to brake gear, breakthrough is in this regard little.
Summary of the invention
The utility model provides a kind of cylinder type bicycle brake device, solves a difficult problem of the prior art, and this brake device structure is simple, and lightweight, easy to use, braking force is strong.
Realizing the technical scheme that the utility model above-mentioned purpose adopts is:
A kind of cylinder type bicycle brake device, at least comprise brake handle, brake rubber block, brake lever and oil pipe, described brake lever is cylinder type structure, brake lever is made up of sleeve, expansion link and mount pad, described sleeve is cylindrical tube shape, the bottom of sleeve is provided with oilhole, and the inside of sleeve is filled with hydraulic oil; Described oil pipe, in " people " font, is made up of a supervisor and two looped pipelines, and one end of supervisor is with brake being connected, and one end of looped pipeline is connected with oilhole, and the other end of described supervisor and two looped pipelines is interconnected in " people " font; The bottom of described expansion link is installed in sleeve and also can slides up and down in sleeve, the top of expansion link stretches out in outside sleeve, expansion link is hollow shape, its inside is provided with chamber, the bottom of expansion link is unenclosed construction, be provided with extension spring in described chamber, the top of extension spring is fixed on the top of chamber, and the bottom of extension spring is stretched out by the bottom of expansion link and is fixed on the inwall of sleeve; Described mount pad is fixed on the top of expansion link, and brake rubber block is installed on mount pad.
Described brake rubber block is disassembling braking skin.
Outer wall in the middle part of the bottom of described expansion link and expansion link is provided with protruding stop block, and the edge, top of sleeve is provided with ring flange inwardly, and described flange contacts with the outer wall of expansion link.
Compared with prior art, the utility model has the following advantages: the hydraulic ram that have employed that 1, the cylinder type bicycle brake device that provides of the utility model is breakthrough is braked, and braking force is large, safe and reliable.2, because brake lever in this brake gear can be stretched braking, compared to traditional binder, apply the brakes arm is not needed, therefore, it is possible to reduce weight significantly.
Accompanying drawing explanation
The structural representation of the cylinder type bicycle brake device that Fig. 1 provides for the utility model;
In figure: 1-brake rubber block, 2-sleeve, 3-expansion link, 4-mount pad, 5-oilhole, 6-is responsible for, 7-looped pipeline, 8-extension spring.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed specific description is done to the utility model, but protection domain of the present utility model is not limited to following examples.
The cylinder type bicycle brake device that the utility model provides at least comprises brake handle, brake rubber block 1, brake lever and oil pipe, described brake lever is cylinder type structure, brake lever is made up of sleeve 2, expansion link 3 and mount pad 4, described sleeve 2 is cylindrical tube shape, the bottom of sleeve 2 is provided with oilhole 5, and the inside of sleeve 2 is filled with hydraulic oil.
Described oil pipe, in " people " font, is made up of a supervisor 6 and two looped pipelines 7, and one end of supervisor 6 is with brake being connected, and one end of looped pipeline 7 is connected with oilhole 5, and described supervisor 6 and the other end of two looped pipelines 7 are interconnected in " people " font.
The bottom of described expansion link 3 is installed in sleeve 2 and also can slides up and down in sleeve 2, the top of expansion link 3 stretches out in outside sleeve 2, expansion link 3 is in hollow shape, its inside is provided with chamber, the bottom of expansion link 3 is unenclosed construction, be provided with extension spring 8 in described chamber, the top of extension spring 8 is fixed on the top of chamber, and the bottom of extension spring 8 is stretched out by the bottom of expansion link 3 and is fixed on the inwall of sleeve 2.Outer wall in the middle part of the bottom of described expansion link 3 and expansion link is provided with protruding stop block, and the edge, top of sleeve is provided with ring flange inwardly, and described flange contacts with the outer wall of expansion link.Stop block and flange can play position-limiting action, prevent expansion link from skidding off outside sleeve.
Described mount pad 4 is fixed on the top of expansion link 3, and brake rubber block 1 is installed on mount pad 4, and described brake rubber block 1 is disassembling braking skin.
The principle of work of the cylinder type bicycle brake device that the utility model provides is as follows: when mounted, sleeve in this brake gear is mounted on front fork or back vent, fixed form can adopt welding or screw thread to fix, and should note making brake rubber block aim at rim during installation.In use, when needs are braked, clutch brake handle, brake in hydraulic oil flow in brake lever along oil pipe under squeezing action, and promote expansion link and move outwardly, until two brake rubber blocks withstand on rim jointly, rim is braked, braking is releasing of brake handle afterwards, and now expansion link bounces back under the pulling force of extension spring, and hydraulic oil is back in brake handle.
