Abstract
The utility model discloses a single-beam shock-absorbing front fork, which is characterized in front forks fixed on a front wheel axle, a curve single-beam hinged with the end of the front forks, and a longitudinal vertical tube connected to the upper part of the curve single-beam for fixing a front handle; a pressure-reducing and shock-absorbing spring is fixed between the curve single beam and the front forks; a positioning device is also positioned between the curve single-beam and the front forks. A horizontal lever is fixed between the front forks; one end of the pressure-reducing and shock-absorbing spring is fixed on the horizontal lever, and the other end is fixed on a spring fixing seat at the bottom of the curve single-beam; the positioning device is a support post for the curve single-beam, of which the position is corresponding to that of the horizontal lever. With the above structure, the single-beam shock-absorbing front fork has advantages of simple structure, convenient maintenance and low cost, and is widely applicable in improvement of front forks of all bicycles and motorcycles.
Description
Technical field
The utility model relates to the front forks such as bicycle of the front fork, particularly a kind of damping of bicycle etc.
Background technology
Usually bicycle does not have shock absorbing apparatus, more existing high-grade bicycles (mainly being mountain bike) are equipped with the shock absorption device that is made of spring and hydraulic actuating cylinder or cylinder at the front fork place, as application number is 93207193, the applying date is on March 27th, 1993, denomination of invention is the patent application of mountain bike shock-absorbing front fork, this single-beam shock-absorbing front fork, the front fork shoulder is fixed two piston barrels, insert in the pipe of fork blade hollow the bottom of piston barrel, between liner piston ring is arranged, the lower surface of piston barrel is installed with a piston rod, pass two stage clips of size diameter on the piston rod outside piston barrel, and be connected by the screw buckle of piston-rod lower end head in the screw of pipe bottom surface of fork blade hollow.The utility model has the advantages that: reasonable in design, elegant in appearance, be easy to assembling, be convenient to maintenance.In the mountain region or uneven road surface when riding,, drive comfortable because of the damping human body is shaken for a short time.Though the said apparatus shock-proof effect is better, relatively poor its effect of road surface competence exertion, and complex structure, processing and matching requirements precision height, the high and maintenance difficulty of cost.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency and provides a kind of simple in structure, is convenient to keep in repair and adjustable single-beam shock-absorbing front fork with low cost.
For achieving the above object, the utility model has adopted following technical scheme: this single-beam shock-absorbing front fork is bent single-beam by the front fork that is fixed in front wheel spindle, with front fork end pivotally attached and is connected in the vertical standpipe that is used for fixing front handlebar on curved single-beam top, be fixed with the decompression shock-proof spring between curved single-beam and the front fork, also be provided with registration device between curved single-beam and the front fork.
Be fixed with cross bar between the described front fork, decompression shock-proof spring one end is fixed on the permanent seat of cross bar, and the other end is fixed on the spring fixed seat of curved single-beam bottom surface; Establish spring on the described permanent seat and install down adjustment hole.
Described registration device is fixed with cross bar on curved single-beam strut bar being set on the front fork, the position of strut bar is corresponding with the cross bar position.
Described curved single-beam and standpipe coupling end also are provided with the direction resistance.
The beneficial effects of the utility model are: when vehicle pitching, front fork of the present utility model and curved single-beam are invisible triangle, secondary fork is presented lower axis and is moved on front fork, stage clip pressurized when front fork moves down connects the spring plate bending of front fork and curved single-beam simultaneously.Spring between front fork and curved single-beam owing to crooked absorb energy and obviously reduce vibrations, to realize damping, the smooth-ride of bicycle etc.Also be provided with registration device between curved simultaneously single-beam and the front fork, thus before guaranteeing certain height, prevent to bend between single-beam and the front fork and contact with each other, and the compressive strength of assurance spring.The utility model is simple in structure, and requirement on machining accuracy is not high, and easy to maintenance, with low cost, good damping effect; The front fork that can be widely used in various bicycles, motor bike etc. improves.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is a sectional perspective structural representation of the present utility model.
The specific embodiment
As Fig. 1-shown in Figure 2, single-beam shock-absorbing front fork of the present utility model by front fork 8 on the axle 11 that is fixed in front-wheel 10, with front fork 8 ends by the curved single-beam 3 of axle 7 pivotallys attached be connected in the vertical standpipe 1 that is used for fixing front handlebar on curved single-beam 3 tops, be fixed with decompression shock-proof spring 5 between curved single-beam 3 and the front fork 8, curved single-beam 3 is provided with spring fixed seat 4, establish spring on the described permanent seat 4 and install down adjustment hole, height up and down when being used for mounting spring; Front fork 8 is provided with cross bar 9, and decompression shock-proof spring 5 one ends are fixed on the cross bar 9, and the other end is fixed on the curved single-beam 3 bottom surface spring fixed seats 4; Also be provided with registration device between curved single-beam 3 and the front fork 8, this registration device is provided with two strut bars 6 for both sides on curved single-beam 2, and the position of strut bar 6 is corresponding with cross bar 9 positions, when spring 5 compressions, the following movable end of strut bar 6 withstands cross bar 9 just, thereby reaches spacing purpose; Described curved single-beam 3 also is provided with direction resistance 2 with standpipe 1 coupling end, and this direction resistance 2 is by being fixed on the curved single-beam
The type fixed link constitutes, and this direction resistance can be used for preventing the wheel tune.
