Abstract

The utility model provides a bicycle front wheel integrated antideviation side fork locating shock absorbing fork, which is composed of a steering (fixing) fork, a rocking arm, an antideviation side fork, and a spring, wherein, the lower end of the antideviation side fork is connected with the lower end of the steering fork. The needle pin of the upper end of the antideviation side fork passes through a pin hole fixed at the center of a spring base support at the upper end of the steering fork, and a spring base arranged at the fork shoulder of the antideviation side fork is connected by a spring with the spring base support at the upper end of the steering fork. The utility model has the advantages of simple structure and convenient installation and maintenance. Special tools and professional maintenance personnel are not needed, and people who know a little about the mechanical common sense can freely assemble, disassemble and maintain. Especially, the shock absorption effect is obvious, which causes the rider to feel more comfortable. The utility model is also suitable for various types of manual tricycles, electricity-assisted bicycles, wheelchairs, miniwatt two-wheeled motorbicycles, miniwatt three-wheeled motorbicycles.

Description

Bicycle front-wheel integral type deviating prevention side fork location shock-absorbing fork

Technical field:

The utility model relates to a kind of shock absorption device of bicycle, especially a kind of bicycle front-wheel integral type deviating prevention side fork location shock-absorbing fork.

Background technology:

Being seen on the market at present bicycle front-wheel shock absorbing apparatus, structure type is single, from outside to watch all are cartridge type retractor devices of the directly imitative woman style motor bike of 100C four stroke, but because bicycle front-fork tube is shorter, its flexible stroke and spring capacity all are subjected to certain limitation, so the damping effect of the flexible shock absorbing apparatus of this type of cartridge type and not obvious.

Summary of the invention:

In order further to improve the damping effect of bicycle front-wheel, the utility model provides a kind of external spring loaded shock-absorbing fork, and this shock-absorbing is pitched the vibrations that can bring into play the shock-absorbing effect to greatest extent and make the road surface reach vehicle body and reduced to minimum.

Technical solution adopted in the utility model is:

When bicycle pedal foot-operated when getting on or off the bus and turning, all can produce a kind of axial thrust on the wheel, just fail to display owing to wheel is installed on the fixation fork that does not have shock-absorbing, if but but when being contained in the constraint of neither one united and coordinating on the movable damping rocking arm situation just different.Each performs its own functions (independent springing respectively being arranged as motor bike) to suppose the ununified wheel shaft left and right sides shock-absorbing that retrains, so, car is when turning inclined to one side side, while because the axial drag that the gyro principle effect produces causes the both sides spring to loosen compresses and the together inclined to one side side of wayward wheel and vehicle body.Therefore bicycle front-wheel shock-absorbing is if not making the same structure of motor bike, and that just must look for a kind of united and coordinating mode in addition.This deviating prevention side fork designs for the key role that solves the coordinating and unifying just.

The utility model mainly by turn to (fixing) fork, rocking arm, deviating prevention side fork (can bob with respect to steering fork during because of its work, thereby also be called movable fork), and spring form.The deviating prevention side fork lower end is connected by rocking arm with the steering fork lower end, and deviating prevention side fork upper end needle pin passes the pin-and-hole at the bracket assy., spring seat center that is fixed on the steering fork upper end, and deviating prevention side fork fork shoulder place is provided with on spring perch and the steering fork and is connected with spring between the bracket assy., spring seat.

The beneficial effects of the utility model are: simple in structure, installation and maintenance convenience, need not special tool and specialized maintenance personnel, and understand that slightly mechanical general knowledge is detachable and maintenance, especially damping effect is obvious, makes the rider more feel comfortable.

Among the figure, steering fork 1; Deviating prevention side fork 2; Grab a rocking arm 3; Spring 4; Pin 5,6; Bracket assy., spring seat 7; Limit screw cap 8; Center needle pin 9.

The specific embodiment:

As figure.Bracket assy., spring seat 7 is fixed on steering fork 1 upper end, grabbing a rocking arm 3 tail ends is connected with pin 5 with steering fork 1 lower end; the rocking arm interstitial hole is connected with pin 6 with deviating prevention side fork 2 lower ends; deviating prevention side fork needle pin 9 passes the pin holes in the fixing bracket assy., spring seat in steering fork 1 upper end; shock-proof spring 4 is connected on the fixing pin holes stand spring seat in the spring perch at deviating prevention side fork 2 fork shoulder places and steering fork 1 upper end, and deviating prevention side fork needle pin 9 tops screw on limit screw cap dislocation when preventing that movable fork from beating.

Deviating prevention side fork and needle pin can be made multiple version.Deviating prevention side fork 2 left and right sides armed levers and center needle pin 9 can make one fixing whole, left and right sides armed lever and have wherein: 1. casting with the connection mode of center needle pin; 2. forge; 3. welding; 4. riveted joint; 5. bolted connection.See Fig. 4, stretch as needle pin on deviating prevention side fork 2 armed levers are direct, middle in aggregates with whippletree connection; Or left and right sides armed lever connects earlier, then stretches out two again in symmetric position and is linked to be a single-piece needle pin with armed lever.See Fig. 5.

Deviating prevention side fork can be divided into preposition and rearmounted two kinds of forms again, and preposition promptly have deviating prevention side fork to be installed on steering fork side before, is illustrated in figure 1 as forward type; As by changing the deviating prevention side fork size, with direction shown in Figure 1 transfer counter be rear-mounted.

Its working process is: the shock-absorbing aspect, and wheel reaches activity from the movable end of the shockproofness of jolting by rocking arm of road surface impression and sticks, and sticks the absorption of top spring and is weakened through movable; Anti-inclined to one side side face, deviating prevention side fork is that left and right sides armed lever and center needle pin fuse, and is passed the support pin-and-hole of steering fork upper end and is played the unified effect of moving of control left and right sides rocking arm by the center needle pin again.By such structure, no matter left and right sides rocking arm has great out-of-balance force, can both be consistent under the constraint of needle pin, when pushing away (resisting) power when running into axially, since the deviating prevention side fork needle pin can only be in pin-and-hole bob and can not swinging, thereby stopped wheel and inclined to one side side takes place the vehicle body vertical line.

The utility model also is applicable to manual tricycle, and polytypes such as electric power mini-motorcycle, wheel Wheel-chair, miniwatt two-wheeled, motor-tricycle.
