Description

A kind of bicycle front fork auxiliary damping device

Technical field

The utility model relates to a kind of bicycle front forks to assist damping device, and concrete function is to make ordinary bicycle (such as: altogether Enjoy bicycle) front fork acquisition shock-absorbing function.

Background technique

With the arrival in shared epoch, miscellaneous shared bicycle is closely bound up with our life, it goes out The worry of our last one kilometers when going on a journey of existing very good solution, allows the facility of communication is greater, makes the trip more random.But at present All there is such a problem in the shared bicycle of ours at one's side, bicycle is shared to save the production cost of shared bicycle by producer The design in terms of damping is not present in complete vehicle structure.Simultaneously in the service life and reduction use process in order to improve shared bicycle The tire of maintenance cost, shared bicycle is also replaced with more durable solid tyre by traditional pneumatic tire.The two designs are solid The economy of shared bicycle is so improved, but sacrifices the most comfort of bicycle.What shared bicycle solved is most The problem of latter kilometer, although urban road situation is preferable now, last one kilometer tends to occur at people's row of both sides of highway Road or shopping mall, for the bicycle of not glissando, road conditions are simultaneously pessimistic for this.Sharing the unique shock-absorbing function of bicycle is exactly Spring under vehicle seat, but without enough compression travels, damping effect is very little.

Utility model content

The purpose of the utility model is to provide a kind of bicycle front forks to assist damping device, is not changing existing front fork structure Under the premise of, it installs an auxiliary device additional, bicycle front fork is made to obtain damping effect.

The technical solution adopted in the utility model is: designing a kind of bicycle front fork auxiliary damping device, is installed on voluntarily Between Chinese herbaceous peony axis and front fork, shock-absorbing function is exercised instead of front fork.The device includes damper and " knife font " front fork fixing frame.Institute Stating damper is conventional damper formula damper, and lower end is designed to be fixedly connected as an entirety with bicycle front axle bayonet.Subtract Shake device upper end and " knife font " front fork fixing frame are interconnected to constitute an entirety.Ordinary bicycle front fork is solid across the front fork The fixed axis connection of front fork in the center for determining frame and its bottom.Bicycle front fork is connected by the front fork fixing frame and damper dislocation It is connected into as an entirety, the front fork fixed and the front fork fixing frame can move up and down with damper top.

Further, the upper end of the damper is provided with front fork fixing frame locating slot.

Further, there is the positioning pin matched with the damper on the front fork fixing frame top.

Further, there are two front fork positioning columns for the front fork fixing frame upper right side design.

Further, the front fork fixing frame side is provided with reinforced support.

Further, front fork fixing frame side hollow out, the total quality of alleviator.

Further, the size design of the front fork fixing frame is reasonable, it is made to move to compression with absorber spring The slightly above position of wheel front axle when stroke minimum point guarantees that movement will not occur for front fork and front wheel dry in motion process It relates to.

According to the above aspect of the present invention, the utility model has the advantage that the apparatus structure is simple, rationally, front fork is fixed for design Reinforcing means are taken in frame side, actually use stronger reliable.Described device can not change original bicycle front fork knot Ordinary bicycle is set to realize shock-absorbing function under the premise of structure.It has largely been launched in view of shared bicycle, installing the device additional can So that original bicycle front fork is retained, will not result in waste of resources.The damper bullet that the front fork assists damping device to use Spring compression travel is enough big, and obtained damping effect is more preferable, the comfort of significant increase bicycle riding.

In utility model figure: 1 damper；101 bicycle front axle bayonets；102 threaded holes；The positioning of 103 front fork fixing frames Slot；2 front fork fixing frames；201 reinforced supports；202 front fork positioning columns；203 front fork fixing axles；204 positioning pins；205 bolts hole； 206 fastening nuts.

Specific embodiment

The utility model is described in detail below in conjunction with diagram.

Referring to Fig. 3, which is a kind of bicycle front fork auxiliary damping device, which includes damper 1 and " knife 2 two parts of font " front fork fixing frame.

Damper 1 is traditional damp type damper, and lower end is designed to be fixedly connected with 101 phase of bicycle front axle bayonet The form being integrated.The upper surface design of damper has threaded hole 102, for fixing " knife font " front fork fixing frame 2.Before making Insert fixed frame 2 to be less likely to occur to loosen, and remain and do not change with the relative position of damper, damper upper end also Devise the locating slot 103 of front fork fixing frame.

2 Design of Main Structure of front fork fixing frame is " knife font ", and upper surface setting is for the bolt fixed with 1 phase of damper The positioning pin 204 matched with 1 upper surface of damper is arranged in hole 205, the two sides of bolt hole 205.The upper right side of front fork fixing frame 2 Design there are two front fork positioning column 202, by installation effect Fig. 4 as it can be seen that bicycle front fork can be by two columns among, and gap is very It is small, it can be good at limiting moving forward and backward for bicycle front fork, be linked together it utmostly with the device.Front fork fixing frame 2 bottom is front fork fixing axle 203, and former bicycle front fork bayonet can be fixed here by nut, and front fork fixing axle 203 rises The effect of former wheel front axle is arrived.The side of front fork fixing frame 2 is provided with reinforced liner 201, which uses truss structure, Structure is simple, durable.The lower part of front fork fixing frame 2 is designed as the indent of certain angle, and such setting is just and voluntarily Chinese herbaceous peony fork tilt angle be adapted, while guarantee the device installation after front fork still there are certain inclinations with the normal of horizontal plane Angle.

Front fork fixing frame 2 is designed and sized to fix from the bottom surface of the bolt hole 205 of 2 upper end of front fork fixing frame to front fork The lowermost length of frame should be slightly less than the sum of upper dimension (more than spring) and spring-compressed stroke of damper 1.It sets in this way The front fork fixing frame of meter could avoid front fork that movement interference occurs with wheel due to moving downward at work.

The working principle of the utility model are as follows: when people take bicycle, due to self gravity, front fork damping dress It sets and is compressed downwardly 3~5cm immediately, such compression travel only leans on the spring on vehicle seat cannot achieve.It rides and encounters top Winnow with a dustpan road surface when, damper under the effect of gravity responds road conditions, since bicycle front fork is fixed together with damper , so front fork can also move up and down with damper top, so that former bicycle front fork be made to obtain shock-absorbing function.The device subtracts Device stroke is shaken close to 20cm, removes the 3~5cm for compressing it naturally because of self gravity, there is also about more than the compression of 15cm for damper Amount guarantees the comfort during riding enough.When the emergency braking in ride, cycle frame and front fork can be because used Property and lean forward, this impact allows for front fork and easily loosens from fixed frame 2, and therefore, the front fork positioning column 202 of design is good The displacement of front fork in the longitudinal direction is limited, impact of the front axle bayonet to 2 lower end of front fork fixing frame is reduced.

The above is the utility model preferred embodiment, cannot limit the scope of the utility model with this, practical according to this Within novel structure and principle, any variation, replacement, improvement etc. should all be comprising within the protection scope of the utility model.
