Abstract
The utility model discloses a motive power drive mechanism for an entertainment car for children. The pedals of the mechanism swing up and down to drive a unidirectional roller type overrunning clutch connected with a connecting rod to make a wheel shaft to rotate to drive wheels to move forward. In order to reduce the friction loss during the driving process, a rolling bearing is arranged on a shaft to support the car body. The utility model has the advantages of simple device and convenient manufacture; the car adopting the motive power drive mechanism has the advantages of light operation, flexible turning, convenient running, etc.
Description
The utility model is a kind of children recreational vehicles of playing, and is particularly useful for the power drive of lorry.
The power drive of common four-wheel children roadlice mostly adopts piston crank mechanism to realize the running of wheel, promptly hind axle is made crank shaft, with connecting rod this axle is coupled together with step, the occupant steps on step, just can make the crank shaft rotation by connecting rod, thereby the rotation trailing wheel, driving trolley is advanced.But this kind type of drive exists class-one defect in practicality, and it requires the swing of step to coordinate be in step with the rotation of crank shaft, otherwise can produce " dead point " and can't advance, and this is difficult to accomplish to the child.In addition, when turning, can't make two trailing wheels produce differential, cause turn radius big, inconvenience etc.
Task of the present utility model is: at above-mentioned weak point, design a kind of new power drive, its driving is light, and tuning is flexible, is more suitable for the requirement of entertainment for children vehicle power transmission easy operation.
Solution of the present utility model is: adopt the step type of drive, two steps are connected symmetry respectively with connecting rod be installed in one-way type roller overrunning clutch on the hind axle.The outer shroud of power-transfer clutch is hinged with connecting rod and step, and the star-wheel of power-transfer clutch is contained on the hind axle.The assembling of star-wheel and hind axle can be adopted what fixed form of opinion, as: key or bolt etc.The bearing of hind axle upper support car body adopts antifriction-bearing box, and directly processing is on wheel shaft the interior raceway of bearing in order to reduce size and cost-cutting, and hind axle and bearing steel ball direct contact, outside race adopt thrust bowl-type circle.
Power drive of the present utility model, simple in structure, to handle lightly, the out-of-alignment power-transfer clutch drives two trailing wheels respectively, can regulate rotating speed separately at any time, has solved " dead point " that the drive system reseting procedure may cause the stop phenomenon of being obstructed effectively.Two steps can be stepped in turn, also can step on individually or simultaneously, also do not require step swing up and down must and wheel revolutions coordinate to be in step with.This driving device activity is fit to children's action and muscle power freely more.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the birds-eye view of Fig. 1
Embodiment of the present utility model is: four-wheeled is turned to by bearing circle (3) control front-wheel (1), step (4) is installed on the front wheel carrier fulcrum (P) with the pivotally attached mode, step (4) can be swung around fulcrum (P), two star-wheel one-way type roller overrunning clutches (7) symmetry is installed on two hind axles (8), have location retaining bolt hole on the star-wheel of power-transfer clutch (7), the end of wheel shaft (8) has the hole of matching with retaining bolt hole on the star-wheel, with bolt the star-wheel of power-transfer clutch (7) is fixed on the axle (8).The outer shroud of power-transfer clutch (7) adopts the mode that is hinged to link to each other by connecting rod (5) and step (4).Two antifriction-bearing boxs (9) respectively are housed on the hind axle (8), raceway is directly processed on wheel shaft (8) in the steel ball of antifriction-bearing box (9), unidirectional thrust bowl-type circle is adopted in the outer ring of antifriction-bearing box (9), thrust bowl-type outer ring the rim of a bowl face of two bearings (9) on the every axle (8) is opposite, plays two-way thrust function.The outer ring of antifriction-bearing box (9) is affixed with vehicle frame or car body, and car body passes through the steel ball supporting of bearing (9) on hind axle (8).
During driving, occupant's handgrip bearing circle (3), pin is trampled pin (4), during along front directive effect step (4), just pass through connecting rod (5) by step (4), the outer shroud that drives power-transfer clutch (7) rotates, the outer shroud of power-transfer clutch (7) drives roller and is rolled into to the star-wheel angle of wedge and blocks under the effect of friction force, outer shroud and star-wheel wedging drive trailing wheel (6) and rotate, and order about vehicle body and advance.When step (4) resets under the effect of extension spring (1), the outer shroud backward rotation of power-transfer clutch (7), roller in the power-transfer clutch (7) rolls from the star-wheel angle of wedge, the outer shroud and the star-wheel slippage of power-transfer clutch this moment (7), and star-wheel continues to surmount forward rotation by the inertia that advances of car body.After step (4) resets, can continue next action.
Claims (3)
1, a kind of by step (4), the carriage for children power drive that connecting rod (5) constitutes, it is characterized in that it comprises that symmetry is installed in the one-way type roller overrunning clutch (7) on two hind axles (8), the star-wheel of power-transfer clutch (7) is separately fixed on the hind axle (8) with key or bolt, and the outer shroud of power-transfer clutch (7) and two steps (4) use connecting rod (5) to be hinged respectively.
2, device according to claim 1 is characterized in that the interior raceway of antifriction-bearing box (9) is directly processed on wheel shaft (8), and car body is supported on the wheel shaft (8) by the steel ball of bearing (9).
3, device according to claim 1 and 2, the outer ring that it is characterized in that antifriction-bearing box (9) are unidirectional thrust bowl-type circles.
