Abstract
The utility model discloses a front fork for a bicycle. A vertical pipe of the front fork is fractured into an upper segment and a lower segment in a radial direction. The butt joint point of the upper segment and the lower segment of the vertical pipe of the front fork is provided with a shock absorbing apparatus, and the upper segment and the lower segment of the vertical pipe of the front fork are butted into integration through the shock absorbing apparatus. When a bicycle is ridden, under the jolting effect of the irregular earth surface, the fractured vertical pipe of the front fork for a bicycle with the structure bends, and the shock absorbing apparatus at the fractured point can absorb shaking force produced by jolting, so the strong shock force felt by a rider can be avoided. The utility model can increase comfort when the bicycle is ridden.
Description
Technical field
The utility model relates to a kind of bicycle front fork, and is especially relevant with the shock absorbing device of bicycle front fork.
Background technology
Traditional bicycle, in order to guarantee the whole impregnability of vehicle body, whole vehicle frame is to be made by metal tube, front fork is no exception, this bicycle, vehicle body is heavy, carries inconvenience.The back is along with the appearance of a kind of light weight, fiber reinforced composite material that intensity is high, and whole vehicle frame is made by fiber reinforced composite material, and the problem of " vehicle body is heavy, carries inconvenience " just makes to solve.But, no matter be metal control front fork, or composite material system front fork, because front fork is structure as a whole, as shown in Figure 1, in driving, in case be subjected to the effect of jolting of ground relief, the vibrations that it produced can't be eliminated, and can directly be passed to cyclist's both hands, the cyclist will experience great jarring forces, particularly for the people of motion by bike, its shock effect has influenced the effect of motion especially greatly, by dealer and cyclist worry.
Summary of the invention
The purpose of this utility model provides a kind of bicycle front fork, has shock absorbing device, the vibrations that can absorb in the process of driving to be produced.
For reaching above-mentioned purpose, the technical solution of the utility model is as follows:
A kind of bicycle front fork, standpipe of front fork radial fragmentation are divided into upper and lower two sections, and the upper and lower two sections joint of standpipe of front fork is provided with shock absorbing device, and upper and lower two sections of standpipe of front fork are one by shock absorbing device butt joint.
Above-mentioned standpipe of front fork upper and lower two sections in the corresponding necking segment that forms of joint, shock absorbing device is fixed on the necking segment.
Above-mentioned shock absorbing device is made up of reinforcing body, elastic gum and outer tube, reinforcing body is axially disposed within the upper and lower two sections joint of standpipe of front fork, outer tube is nested with outside the upper and lower two sections joint of standpipe of front fork, elastic gum is in the outer tube, and be filled in all gaps, make it to become an integral body.
Above-mentioned standpipe of front fork upper and lower two sections at the corresponding axial notch that forms of necking segment, reinforcing body is arranged in this axial notch.
The upper and lower two sections axial notch of the corresponding standpipe of front fork of the inwall of above-mentioned outer tube also forms axial groove.
After adopting said structure, the utility model is owing to be divided into upper and lower two sections with the standpipe of front fork radial fragmentation, and be provided with shock absorbing device at upper and lower two sections joint, so, in driving, if be subjected to the effect of jolting of ground relief, the shock absorbing device of fracture place can absorb the shaking force that jolts and produced, thereby avoid the cyclist to experience great jarring forces, help to promote comfort by bike.
Description of drawings
Fig. 1 is a structural representation of commonly using product;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the axial, cross-sectional view of Fig. 2;
Fig. 4 is the view in transverse section of Fig. 3.
Specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment, the utility model is described in further detail.
At first, see also shown in Fig. 2,3, the bicycle front fork that the utility model discloses, in position radial fragmentation is divided into upper and lower two section 1,2.
Cooperate shown in Figure 4ly, upper and lower two section 1 of standpipe of front fork, 2 at corresponding necking segment 11,21, two necking segment 11, the 21 corresponding axial notches 12,22 that form that form of joint.Shock absorbing device 3 is fixed on the necking segment 11,21.
Use bicycle of the present utility model, in driving, if be subjected to the effect of jolting of ground relief, fixing shock absorbing device 3 can absorb the shaking force that jolts and produced on upper and lower two section 1 of standpipe of front fork, 2 the necking segment 11,21, thereby avoid the cyclist to experience great jarring forces, increase comfort by bike.
