Abstract
The invention discloses a shock absorber for a motorbicycle. The shock absorber comprises a spring (3), and is characterized in that: the lower end of the spring (3) is fixed with an axle (5), while the upper end is respectively correspondingly connected with two ends of a U-shaped rod (2) which is horizontally arranged; positioning mechanisms which are correspondingly fixed with bottom pins of a moped supporting frame (1) are arranged on the front part of the U-shaped rod (2) respectively; and connecting structures which are connected with corresponding arms on the supporting frame (1) are arranged on the rear part of the U-shaped rod (2) respectively. Compared with the prior art, the shock absorber has the advantages that: the U-shaped rod has a strong structure and the lower end of the spring is fixed with the axle through a nut, so the structure is firm and stable, and the supporting frame of the motorbicycle can be shortened; therefore, the shock absorber is convenient to install, and the material of the supporting frame of the motorbicycle can be reduced; the shock absorber saves the cost and has better shockproof effect; and the innovative structure is practical and deserves popularization and application.
Description
Technical field
The present invention relates 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, and 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, and service life is shorter; Also need the bracing frame of mini-motorcycle be changed structure during use; 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 matters to be solved by this invention is to above-mentioned prior art present situation a kind of Shock absorber that is used on the mini-motorcycle reasonable in design, easy for installation and well-set to be provided.
The present invention 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 said 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 in the front portion of U-shaped bar and the corresponding detent mechanism that fixes of mini-motorcycle bracing frame footing, and be respectively arranged with on the rear portion of U-shaped bar with bracing frame on the connection structure that is connected of counterpart arm.
As improvement; Said detent mechanism comprises preferably positioning frame body; In positioning frame body, being provided with the back-shaped chamber that can place the U-shaped bar, is the U-shaped chamber above back-shaped chamber, in the U-shaped chamber, is provided with two ends and is 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, the posting physical efficiency is fixed on the U-shaped bar more firmly, more neatly like this.
Improve again; Said 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 bottom of axle sleeve be provided with can axle sleeve be positioned with the U-shaped bar on hold out against screw, like this design can make axle sleeve can be more flexibly, more reasonably on location and the U-shaped bar.
Improve, said 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 through the nut and the wheel shaft on wheel shaft both sides, make like this spring leaf can be more easily, be installed on the wheel shaft more firmly.
Improve, its connecting portion of said axle sleeve interconnects with the counterpart arm of bracing frame respectively through spring, thereby makes the front and rear part of U-shaped bar all can play shockproof effect again.
Compared with prior art; The present invention 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 and the corresponding detent mechanism that fixes of mini-motorcycle bracing frame footing in the front portion of U-shaped bar, and be respectively arranged with on the rear portion of U-shaped bar with bracing frame on the connection structure that is connected of counterpart arm.Its advantage is: U-shaped bar structure is sturdy; And the spring leaf lower end is mutually firm with wheel shaft through nut, so sound construction is stable, and the mini-motorcycle bracing frame also can shorten; So not only easy for installation, but also can reduce the material of mini-motorcycle bracing frame and practice thrift 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 by bike the time, to feel more comfortable shock-proof effect; Therefore the structure of this innovation is very practical, is worthy of popularization.

The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Like Fig. 1 to shown in Figure 6, present embodiment be used for the 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 mini-motorcycle 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; Be U-shaped chamber 41 above back-shaped chamber 43, 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 the fixing screw 44 on the U-shaped bar 2.And be respectively arranged with on the rear portion of U-shaped bar with bracing frame 1 on the connection structure that is connected of counterpart arm; 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 can axle sleeve 6 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 through spring 7.
