Abstract
The utility model provides a manual driving device of rickshaw. The wheel axles of two back wheels is provided with flywheels with mutual reversal meshing. The front of the two flywheels are provided with chain commutation pulleys. The two ends of the chains which is supported by the pulleys are hung on the two flywheels respectively to make the flywheels rotate along the same direction. The two ends of the chains are fixed respectively at the upper and lower sides of the push and pull handspike. The utility model has the advantages that it can be applied for not only wheel chair for the disabled but also double three-wheeler for body-building. The one which is used for former is labor saving in pull and push and the speed is faster. The utility model for the latter makes the three-wheeler also has the function of exercising arm.
Description
The utility model belongs to the driver train of rickshaw, relates to a kind of manual driving device.
Existing Wheelchair is used manual drives mechanism always, be in the flywheel of hind axle by the band chain drum of cranker and chain gear, be characterized in the cranker folk prescription to driving, exist and unilaterally shake crank arm action radius big fatigue and the slower deficiency of actuating speed easily for a long time.In addition, along with the generally raising of health of people consciousness, double body-building three-wheel vehicle rises.But no matter its seat is forward double or is provided with dorsad that its driver train all adopts foot-operated mode.Obviously, existing body-building three-wheel vehicle lacks the suitable exercise to arm.
The purpose of this utility model provides the needs of a kind of wheelchair that can adapt to the disabled person and body-building three-wheel vehicle and overcomes the rickshaw manual driving device of its existing driver train defective.
Comprise chain and flywheel in the technical scheme of realization above-mentioned purpose, its concrete scheme is: reverse each other ingear flywheel is set on the wheel shaft of fixing two rear wheels in pairs, the vehicle frame of two flywheel front sides is provided with the chain angle pulley, the chain that is supported in this pulley is mounted on each flywheel respectively, two flywheels are with the equidirectional rotation of chain row culture of motion, axle bearing is fixed with the tractive cable wire respectively in the upper and lower body of rod of its both sides of push-and-pull hand lever of vehicle frame, and each cable wire is connected with the chain two ends respectively.
The set tractive cable wire of the pivot shaft upside body of rod of said push-and-pull hand lever is provided with the angle pulley that is supported by vehicle frame.
Said angle pulley, its support axle is provided with horizontally-arranged chain tension at vehicle frame and adjusts the thread segment in the slotted hole and be positioned at the jam nut of adjusting the slotted hole both sides.
Said push-and-pull hand lever, its end are provided with the lever that is supported by transverse axis.
The technical program has following outstanding advantage: to make the action radius of reciprocating sliding campaign little than cranker for arm when 1, being used for Wheelchair, and crank motion all can drive wheelchair and move ahead, its resultant effect is that gait of march is comparatively fast laborsaving again, and the tired program of arm can obviously alleviate.2, be used for the pedal drive mechanism that double body-building three-wheel vehicle replaces afterburning seat, and identical two these devices of cover be set, can effectively remedy existing body-building vehicle and lack the defective that arm strength is taken exercise at hind axle and vehicle frame.
Below in conjunction with drawings and Examples explanation the utility model.Accompanying drawing 1 the utility model structural representation accompanying drawing 2 Figure 1A are to view
As shown in Figure 1, 2, fixedly the wheel shaft 1 of both sides trailing wheel be provided with the double-type flywheel 2,2 of reverse each other ingear ', after same chain 3 cws are mounted on flywheel 2, through chain angle pulley 4 conter clockwises be mounted on flywheel 2 ', chain angle pulley 4 by axle bearing in paired flywheel 2,2 ' front side vehicle frame 10.Chain one end of flywheel 2 is fixed in the bottom of push-and-pull hand lever 6 by tractive cable wire 5, flywheel 2 ' chain one end by tractive cable wire 5 ' be fixed in pivot shaft 11 tops of push-and-pull hand lever 6 through angle pulley 9.The end of push-and-pull hand lever 6 is provided with the lever 7 that is supported by transverse axis.In order to make chain tension, the support axle of angle pulley 9 is provided with horizontally-arranged thread segment in being fixed in slotted hole plate 8 slotted holes of vehicle frame, and this section is provided with jam nut in slotted hole plate both sides.
Course of action of the present utility model is: suppose that at first flywheel 2 is the cw engagement among Fig. 2, flywheel 2 ' be that conter clockwise meshes, when push-and-pull hand lever 6 upper ends towards diagram right side when pulling, flywheel 2 is a reverse slide under cable wire 5 and chain effect, in the same way the flywheel 2 of Zhuan Donging ' then be in engagement.When if push-and-pull hand lever 6 upper ends promote towards diagram left side, cable wire 5 ' make flywheel 2 ' oppositely skid, and flywheel 2 engaged transmission.As seen the push-and-pull hand lever crank motion of this device all can drive trailing wheel and moves ahead.
Claims (4)
