Description
Technical field
The utility model belongs to bicycle assembly parts technical field, particularly relates to a kind of new bicycle shock-proof front-fork assembly.
Background technology
Front fork is one of vitals of bicycle, as the turning member of bicycle, structure generally comprises superposed fork arm, be positioned at the support at middle part and be positioned at two relative breeches pipes of below, wherein fork arm is used for being connected with the front fork tube of vehicle frame and at top installation car handle, the lower end of two breeches pipes is provided with forks piece and is connected with the axle of front vehicle wheel.For shock-proof front-fork assembly, because needs provide shock-proof effect, therefore need breeches pipe to be designed to telescopic structure, the parts such as damping spring are set in inside shock-absorbing function when riding is provided.
In prior art, the breeches pipe of shock-proof front-fork assembly is inserted in the fork body of an arc fork, in the fork body of arc fork, arrange the parts such as shock-proof spring, and namely in the dynamic process of shock-absorbing, the breeches pipe of front fork is flexible up and down in the fork body of arc fork.The shock-absorption front fork structure of bicycle of said structure is complicated, is not easy to assembling and later stage dismounting maintenance.
Utility model content
The utility model for solve in known technology the technical matters that exists and provide that a kind of structure is simple, assembling and later stage dismounting safeguard new bicycle shock-proof front-fork assembly easily.
The technical scheme that the utility model is taked for the technical matters existed in solution known technology is: a kind of new bicycle shock-proof front-fork assembly comprises the support being positioned at middle part, becoming to be inverted V-arrangement shape, vertical fork arm is installed the midway location of cradle top is affixed, be installed with the vertical breeches pipe of relative two in left and right in the end positions of frame bottom, the upper end closure of breeches pipe is also installed with nut in center; At the inner chamber of each breeches pipe equal plug-in mounting, shock-absorbing arms is installed, shock-absorbing arms is straight tube structure and upper end closure lower end is uncovered, axially through centre hole is offered at the middle part of upper end, long spiro nail is provided with in this centre hole, the nut of long spiro nail is positioned at the inner chamber of shock-absorbing arms, end is tightened on nut, also be arranged with spring in the base portion of long spiro nail, spring is between the roof and the roof of shock-absorbing arms of breeches pipe; Between the inwall and the outer wall of shock-absorbing arms of breeches pipe bottom, be provided with sliding sleeve, be also installed with the termination with forks piece in the bottom of shock-absorbing arms.
Advantage of the present utility model and good effect are: the utility model provides a kind of new bicycle shock-proof front-fork assembly of structure design advantages of simple, compared with existing front fork unit, the technical program is by arranging front fork by fork arm, support, breeches pipe and shock-absorbing arms are formed, and shock-absorbing arms plug-in mounting is set is arranged in breeches pipe and spring and long spiro nail are set between, achieve the pattern of shock-absorbing arms in the damping of fork inner telescoping tube, not only damping effect is excellent, and improve the convenience of whole front fork unit assembling, convenience when simultaneously above-mentioned package assembly in turn ensure that the later stage, dismounting was safeguarded.
Preferably: the upper end of described breeches pipe be inserted into be opened in bracket end groove in and weld affixed.
Preferably: described nut-welding is arranged on the top of breeches pipe.
Preferably: described termination welded and installed is in the lower end of shock-absorbing arms.
Accompanying drawing explanation
