Technical field

The utility model relates to a kind of mini-motorcycle production technical field that is used for, and especially refers to a kind of Shock absorber that is used on the mini-motorcycle.

Background technology

Existing a kind of patent No. has proposed a kind of structure for the Chinese utility model patent that the CN97230379.0 name is called " a kind of leaf spring type elastic force Shock absorber ", its basic comprising is, need three elements to realize the function of Shock absorber, the frictional loss energy is less during work, cost is low, can be applicable to the car fork of bicycle, mini-motorcycle, motor scooter, three-wheel vehicle and handle runner or the suspension system of back vehicle frame.But its shortcoming is: this structure fastness is not enough, fragile, service life is shorter, also need during use the bracing frame of mini-motorcycle is changed structure, spring leaf and bracing frame are flexibly connected, and this structure is not only made trouble, and shockproof structure is thin, effect is undesirable, so its structure awaits to improve.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of Shock absorber that is used on the mini-motorcycle reasonable in design, easy for installation and well-set at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this is used for the Shock absorber on the mini-motorcycle, include spring leaf, it is characterized in that: its lower end of described spring leaf and wheel shaft fix, and its upper end is connected with the two ends of U-shaped bar horizontal positioned respectively accordingly, be respectively arranged with the corresponding detent mechanism that fixes in the front portion of U-shaped bar, and be respectively arranged with the connection structure that is connected with counterpart arm on the bracing frame on the rear portion of U-shaped bar with the bracing frame footing.

As improvement, described detent mechanism comprises preferably positioning frame body, in positioning frame body, be provided with the back-shaped chamber that can place the U-shaped bar, it above back-shaped chamber the U-shaped chamber, in the U-shaped chamber, be provided with two ends and be placed through the transverse axis that is used for fixing the bracing frame footing on the positioning frame body both sides, be provided with the fixing screw that positioning frame body is positioned on the U-shaped bar in the bottom of positioning frame body, like this posting physical efficiency more firm, be fixed on the U-shaped bar more neatly.

Improve again, described connection structure is designed to axle sleeve, this axle sleeve is through on the cooresponding U-shaped bar for overlapping movably, top at axle sleeve is provided with connecting portion, the screw that holds out against that axle sleeve can be positioned on the U-shaped bar is set in the bottom of axle sleeve, like this design can make axle sleeve can be more flexible, more reasonably on location and the U-shaped bar.

Improve, described spring leaf can be preferably designed for arcuate structure again, and its lower end is connected with lasso, and this lasso is fixed with each other by the nut and the wheel shaft on wheel shaft both sides, make like this spring leaf can be easier, be installed on the wheel shaft more firmly.

Improve, its connecting portion of described axle sleeve interconnects with the counterpart arm of bracing frame respectively by spring, thereby makes the front and rear part of U-shaped bar all can play shockproof effect again.

Compared with prior art, the utility model adopts spring leaf lower end and wheel shaft is fixed, and its upper end is connected with the two ends of U-shaped bar horizontal positioned respectively accordingly, be respectively arranged with the corresponding detent mechanism that fixes with the bracing frame footing in the front portion of U-shaped bar, and being respectively arranged with the connection structure that is connected with counterpart arm on the bracing frame on the rear portion of U-shaped bar. its advantage is: U-shaped bar structure is sturdy, and the spring leaf lower end is mutually firm with wheel shaft by nut, so sound construction is stable, and bracing frame also can shorten, so not only easy for installation, but also can reduce the material of bracing frame and save cost; Also have, the design's structure can change the elastic force size according to the size of load carrying ability, realizes making the people to feel more comfortable shock-proof effect by bike the time; Therefore the structure of the innovation is very practical, is worthy of popularization.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 1 to shown in Figure 6, present embodiment be used for Shock absorber on the mini-motorcycle, include spring leaf 3, spring leaf 3 be an arcuate structure, its lower end is connected with lasso 31, nut and wheel shaft 5 that this lasso 31 passes through wheel shaft 5 both sides are fixed with each other.And its upper end is connected with the two ends of U-shaped bar 2 horizontal positioned respectively accordingly, be respectively arranged with and the corresponding detent mechanism that fixes of bracing frame 1 footing in the front portion of U-shaped bar 2, this detent mechanism includes positioning frame body 4, in positioning frame body 4, be provided with the back-shaped chamber 43 that can place U-shaped bar 2, it above back-shaped chamber 43 U-shaped chamber 41, in U-shaped chamber 41, be provided with two ends and be placed through the transverse axis 42 that is used for fixing bracing frame 1 footing on positioning frame body 4 both sides, be provided with in the bottom of positioning frame body 4 positioning frame body 4 is positioned fixing screw 44 on the U-shaped bar 2.And be respectively arranged with the connection structure that is connected with counterpart arm on the bracing frame 1 on the rear portion of U-shaped bar, this connection structure is an axle sleeve 6, this axle sleeve 6 is through on the cooresponding U-shaped bar 2 for overlapping movably, be provided with connecting portion 62 at the top of axle sleeve 6, the bottom of axle sleeve 6 be provided with axle sleeve 6 can be positioned with U-shaped bar 2 on hold out against screw 61.The connecting portion 62 of above-mentioned axle sleeve 6 is to interconnect with the counterpart arm of bracing frame 1 respectively by spring 7.

The utility model installation process is as follows:

The U-shaped bar is by the lasso of spring leaf lower end, it is placed on the wheel shaft, then spiro cap is placed on the wheel shaft in the lasso outside, lasso is fixed on the wheel shaft, then the bracing frame of mini-motorcycle is connected with positioning frame body 4 on being placed on the U-shaped bar, again the fixing screw 44 of positioning frame body bottom is tightened, being about to positioning frame body is fixed on the U-shaped bar, then, one end of spring is connected with axle sleeve on being nested with the U-shaped bar, and the other end of spring is connected with the counterpart arm of bracing frame, tightens then to hold out against screw 61 on the axle sleeve bottom, and axle sleeve is fixed on the U-shaped bar.Front and back wheel is operated equally.Mini-motorcycle promptly has good shockproof effect after finishing.The utility model can be applicable on bicycle, mini-motorcycle, motor scooter, three-wheel vehicle and the handle runner.
