Wherein, 1 is one-level flywheel, and 2 is two grades of flywheels, and 3 is driving dish, and 4 is groups of springs, 41 is outer spring, and 42 is inner spring, and 5 is protuberance, and 6 is groups of springs guide bracket, and 7 is end cap Mark, 8 is storage tank.

Detailed description of the invention

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in Figures 1 to 3, this utility model includes one-level flywheel 1, two grades of flywheels 2 and bullets Spring group 4, wherein one-level flywheel 1 is arranged on the output crank axle of electromotor, two grades of flywheels 2 Being arranged on the power shaft of change speed gear box, two grades of flywheels 2 are coaxially disposed with one-level flywheel 1 and can phases To rotation, described two grades of flywheels 2 are rotated, one-level flywheel 1 He by one-level flywheel 1 It is provided with groups of springs 4 between two grades of flywheels 2.

As shown in Fig. 1～2, described two grades of flywheels 2 are provided with driving near one-level flywheel 1 side Dish 3, described driving dish 3 embeds in described one-level flywheel 1, is provided with on described driving dish 3 Breach and protuberance 5, the breach on described driving dish 3 is separated by protuberance 5, such institute State and between the inner surface of the breach on driving dish 3 and one-level flywheel 1, just form storage tank 8, bullet Spring group 4 is arranged in described storage tank 8, when one-level flywheel 1 rotates by groups of springs 4 with The protuberance 5 of driving dish 3 offsets and promotes two grades of flywheels 2 to rotate, so that groups of springs 4 plays Shock absorbing effect.It is equipped with groups of springs guide bracket 6 often organizing groups of springs 4 two ends, respectively organizes spring Outermost groups of springs 4 and described driving dish 3 is convex between group 4 and in each storage tank 8 Go out and all offseted by groups of springs guide bracket 6 between portion 5.

As it is shown on figure 3, described groups of springs 4 includes outer spring 41 and inner spring 42, described outside Spring 42 is sheathed on inner spring 41.

As in figure 2 it is shown, two groups of bullets mutually abutted that the protuberance 5 of distance driving dish 3 is nearest Groups of springs guide bracket 6 bearing surface between spring group 4 is inclined-plane, and described protuberance is partial on described inclined-plane 5 sides, the angle between described inclined-plane and one-level flywheel 1 radial direction is a, not with arbitrary protrusion Portion 5 abuts and groups of springs guide bracket 6 bearing surface between adjacent two groups of groups of springs 4 flies with one-level The radial direction of wheel 1 overlaps.

As in figure 2 it is shown, be equipped with end cap mark 7, this reality at each groups of springs guide bracket 6 two ends With novel by arranging quantity and the most different groove of arrangement mode on each groups of springs guide bracket 6 Mouth distinguishes each groups of springs guide bracket 6, and two springs mutually abutted as end cap mark 7 Notch quantity on group guide bracket 6 is identical with arrangement mode.As in figure 2 it is shown, with driving dish 3 It is provided with one notch outside the groups of springs guide bracket 6 that protuberance 5 offsets and identifies 7 as end cap, should Be provided with twice notch outside the groups of springs guide bracket 6 of groups of springs 4 other end, inner side is provided with a groove Mouth identifies 7 as end cap, does not abuts with arbitrary protuberance 5 and adjacent two groups of groups of springs 4, Be provided with three road notches outside the groups of springs guide bracket 6 that it mutually abuts, inner side is provided with one notch and makees 7 are identified for end cap.

As shown in figures 2-3, the groups of springs 4 that the protuberance 5 with driving dish 3 offsets is first Groups of springs 4, the groups of springs 4 offseted with described first groups of springs 4 is the second groups of springs 4, institute State length La length Lb more than described second groups of springs 4 of the first groups of springs 4, if one Level flywheel 1 is when rotating counterclockwise, and the protuberance 5 of described driving dish 3 compresses described the One groups of springs 4, owing to groups of springs guide bracket 6 bearing surface of described two groups of groups of springs 4 is deflection institute State the inclined-plane of protuberance 5, the bullet that the most described second groups of springs 4 abuts with the first groups of springs 4 Spring group guide bracket 6 can slide laterally, when length La of the first groups of springs 4 is compressed to less than During length Lb of two groups of springs 4, driving dish 3 starts to rotate under groups of springs 4 acts on, this Time said two groups of springs 4 two the groups of springs guide brackets 6 abutted against are applied power be greater than and work as institute State two groups of springs 4 length equal time the power that applied, therefore, it is possible to increasing friction force, thus Vehicle launch is produced beneficial effect.

Operation principle of the present utility model is:

The nearest two groups of springs mutually abutted of protuberance 5 of this utility model distance driving dish 3 Groups of springs guide bracket 6 bearing surface between group 4 is inclined-plane, and described protuberance is partial on described inclined-plane 5 sides, do not abut with arbitrary protuberance 5 and groups of springs between adjacent two groups of groups of springs 4 Guide bracket 6 bearing surface overlaps with the radial direction of one-level flywheel 1, and the protuberance 5 of distance driving dish 3 is Near two groups of groups of springs mutually abutted 4 are respectively the first groups of springs 4 and the second groups of springs 4, Length La of the first groups of springs 4 is more than length Lb of the second groups of springs 4, when mechanism works, The groups of springs guide bracket 6 that described second groups of springs 4 abuts with the first groups of springs 4 can outwards break away Dynamic, now said two groups of springs 4 applies power and wants big two the groups of springs guide brackets 6 abutted against In the power applied when said two groups of springs 4 length is equal, therefore increasing friction force, this Class effect is for producing useful technique effect during vehicle launch.
