Description

Multi-function brake-actuating device for bicycle

The utility model belongs to a kind of bicycle accessory.

Advancing of epoch promoting the quickening of rhythm of life, and it is very valuable that current social time has become.The modern wishes the health that can keep fit and obtains good stature, yet goes the gymnasium motion but will spend the cooresponding time.It is as the vehicle of riding instead of walk it that present people use bicycle.If can on bicycle, increase by a covering device, make people in by bike, again can be as pedaling the purpose that body-building vehicle reaches sportsing body-building, and don't influence the effect of bicycle operation control itself, this device yet there are no open.

The purpose of this utility model just provides a kind of multi-functional brake damping controller, it is installed on the bicycle, people just can be in way by bike, according to hobby and the needs of oneself, the regulated at will controller changes the motion that the damping of moving strengthens shank, obtains the general train on of running, reach the purpose of sport and body-building, make the bicycle of the purposes of riding instead of walk have the function of health and fitness facilities, be exclusively used in the time of taking exercises, bring convenience for work and life thereby also saved.

As shown in drawings, the multi-functional brake damping controller of the utility model bicycle is a bicycle brake steel wire hinge line by lock screw 1, knob 2, housing 3, lower cover 4, tooth bar 5, axle 6, gear 7, nut 8, bus 9(), support 10 and bus overcoat 11(be bicycle brake hinge line overcoat) form.Axle 6 is stepped shaft, one tapped bore is arranged at its top, knob 2, housing 3, all there is a hole in the central authorities of gear 7, they are installed on the axle 6 successively, gear 7 is below, the shaft shoulder is close in its lower surface, knob 2 is in the top, 6 one-tenth transition fit of gear 7 and knob 2 and axle, housing 3 becomes free-running fit with axle, lock screw 1 is the screw of a band handle, its screw with axle 6 tops connects, make the handle, at its lower end face be close to knob 2 end faces, with knob 2, housing 3, gear 7 is close to together, housing 3 medial surfaces have two tongues, nut 8 just is stuck in the tongue, and the upper and lower surface of tooth bar 5 has two longitudinal slots, and a vertical ladder hole is arranged, difference installation bus 9 and bus overcoat 11 in the through hole, corresponding small one and large one two wire holes on the sidewall of housing 3, gear 7 is meshing with each other in housing 3 with tooth bar 5, and there is a circular protruding circle center, lower cover 4 upper surfaces, insert within it the lower end of axle 6, lower cover 4 with the correspondence position of tooth bar on a bar shaped boss is arranged, become free-running fit with the longitudinal slot of tooth bar 5, a knock hole is arranged on the sidewall of housing 3, with the corresponding position of nut one mounting hole is arranged on the sidewall, lower cover 4 sticks to one with housing 3 usefulness lining cements.Axle 6 cross-sectional plane is an on-circular cross-section, and the shape and size in hole with matching and it are identical on gear 7 and the knob 2.The side surface of knob 2 is the polygon cylinder or the coarse face of cylinder, and showy position, upper surface does that the sign that obtains the damping size is arranged.This controller is installed on the handgrip of bicycle with support 10, and locatees with locating dowel pin.

This reality is made the multi-functional brake damping controller of new bicycle can pass through the damping of knob regulated at will, play the effect of sportsing body-building, also can be not by brake or brake play the effect of drag when damaging, discharge when adjustment control under the situation of damping or damping existence, the operation of brake handle is not affected.It makes bicycle have the function of health and fitness facilities simultaneously, brings convenience for people's live and work.

Accompanying drawing 1 is the longitudinal diagram of this utility model controller.

Accompanying drawing 2 is drawings in side sectional elevation of this utility model controller.

Accompanying drawing 3 is fundamental diagrams of this utility model controller.

Three in detail the embodiment that the multi-functional brake damping of the utility model bicycle is controlled is described in detail with reference to the accompanying drawings below.The left hand that this controller is installed in bicycle is the limit, with behind the locating dowel pin location support being fastened on the tap.One end of bus (bicycle brake steel wire hinge line) is fixed on left side brake last, and the other end is fixed on the brake shoes 12, and the front end of bus overcoat (bicycle brake hinge line overcoat) is installed in the tooth bar, and tail end is fixed in the bicycle body.When clockwise rotating knob, gear just and then rotates, make tooth bar produce the displacement of S to the right, the front end of the mobile drive bus overcoat of tooth bar is followed the distance of displacement S to the right, and the tail end of overcoat is being fixed, therefore overcoat just takes place than original big slightly bending, the front end of the relative overcoat of front end of bus is pulled out the distance of S left at this moment, and the length of overcoat itself does not change, so the tail end of the relative overcoat of tail end of bus is the distance of indentation S just, thereby pulling brake shoes 12 moves the distance of S ' and is pasting wheel rim 13, has just produced frictional damping, and the size of damping is determined by the size of displacement.Because the friction (the friction force size is controlled by lock screw) of knob and housing contact surface makes operation can go up the location at an arbitrary position, the suitable displacement S of turning knob control just can obtain needed kinetic damping.Rotate knob when inhour and just discharged added damping, be normal riding condition this moment.
