Description

Bicycle driven by upper and lower limbs alternately or cooperately

The utility model relates to a kind of improved type bicycle, and particularly a kind of available human body upper and lower extremities replaces, unites the bicycle that driving is travelled.

The ordinary bicycle that uses of people is general now only drives trailing wheel with human body lower limbs and travels, for a long time especially when going up a slope and riding against the wind lower limb feel to be fagged out, and upper limbs can't have been given play to and driven the flesh energy, and the driving effect of bicycle is restricted.Drive the flesh energy for upper and lower extremities all can have been given play to, existing technology is available upper limbs to be installed drive front-wheel or assist to drive the back wheel apparatus on the ordinary bicycle basis.

The patent that CN87205659U announced both on the ordinary bicycle basis, install have drive before the bicycle of wheel apparatus.This device also can be provided with at least one drive spindle around handlebar or around the standpipe around levelling pipe, by palm or the reciprocal work done of pressing drive spindle, drive front-wheel through the propulsive effort combination mechanism that is installed on the front axle again.This device is because f-w-d power derives from palm or the reciprocal work done of pressing drive spindle, and institute is so that the performance of the potential propulsive effort of human upper limb is subjected to certain limitation, and it is steady continuously to be difficult for the assurance f-w-d, causes the f-w-d effect to be affected.In addition also because hand getting drives front-wheel with reciprocal work done, and pin is rotation driving trailing wheel, is unfavorable for that like this trick coordinates to drive car body simultaneously and advance.

The purpose of this utility model be to provide a kind of on the ordinary bicycle basis improved have drive before wheel apparatus, available human body upper and lower extremities replaces, the associating driven bicycle, make its rotation that can give play to human upper limb to greatest extent drive the flesh energy, overcome the deficiency of known technology, with the driving effect of effective raising bicycle.

The purpose of this utility model is achieved in that on the ordinary bicycle basis, with handlebar and front-wheel rotation driving handle, axle drive shaft is combined into one, and make both hands under same orientation angle, be rotated driving simultaneously, again by conical gear and drive link transmission, thereby make steadily failure-free rotation driving front-wheel of both hands, again can actv. control direction of traffic.In addition, when guaranteeing that lower limb independent drive trailing wheel or car body slide, handlebar is to the supporting role that upper limbs rose, the locking device that can not allow it to rotate under the certain orientation angle in the setting of upper limbs rotating driveshaft place; For implementing the control brake, can adopt pin back-pedal control front and back wheel brake gear; For guaranteeing front-wheel normal rotation when only driving trailing wheel and car body and slide, should will in the conical gear that directly links with front shaft sleeve flywheel gear be set.

The advantage that the utlity model has is: because handlebar and front-wheel rotation driving handle, axle drive shaft are combined into one, again by conical gear and drive link transmission, the both rotatable driving front-wheel of both hands like this, can guarantee to control direction of traffic again, so making front-wheel drive simplifies, drive the rotation that steadily reliably can give play to human upper limb to greatest extent and drive the flesh energy, the f-w-d effect is improved, realize easily also simultaneously that the upper and lower extremities joint coordination drives, thereby the upward slope of bicycle and ride the against the wind ability and the speed of a motor vehicle are improved greatly.Again owing to be provided with the locking device that does not allow its counter-rotating, so the high and low angle of handlebar can be selected according to human needs by bike within the specific limits at upper limbs rotating driveshaft place.

Structure of the present utility model is provided by following embodiment and accompanying drawing.

Fig. 1 is the embodiment overall schematic.

Fig. 2 is an embodiment front-wheel drive scheme drawing.

Referring to Fig. 2, (1) is front-wheel rotation driving handle.(17) be front wheel driving shaft.(2) be a conical gear that is fixed on the axle drive shaft (17).(5) be the drive link sleeve, be separately fixed at front fork and stem two places by anchor fitting (6), hinge anchor fitting (11).The effect of hinge anchor fitting (11) is to be used for cushioning and overcoming in the front fork damping process, and the displacement application force that front-wheel produces obliquely upward is to guarantee the good engagement of conical gear.(12) be with front axle interlock be solidified as a whole protect the tooth box, its objective is to reduce the front fork width.(13) be mounted in the flywheel locking device that does not allow front wheel driving shaft counter-rotating in the front wheel driving shaft (17), its Case of fly-wheel is fixed on the rotating shaft cover (14), flywheel idle running when forward drive, and flywheel plays locked effect during counter-rotating.(16) be drive link, its two ends are fixing conical gear (15) respectively, and conical gear (3).Front wheel driving shaft (17) is installed in the rotating shaft cover (14) by axle bowl, axle shelves, steel ball etc.Drive link (16) is installed in the drive link sleeve (5) by axle bowl, axle shelves, steel ball etc.

Referring to Fig. 1, (9) be the coaster brake auritus flywheel of overcoat, it is installed in the axis left side, again with the lock backguy of front and rear brake and lock pull bar respectively by linking with Case of fly-wheel two ears with the fixing support (7) of car body, flywheel idle running when being rotated in the forward the driving car body, flywheel two ears rotate when back-pedal, thereby make front and rear brake backguy and lock pull bar all produce pulling force backward, impel the brake of lock body.Because it is more that rear wheel brake is used, so be connected into a spring (8) that pulling force is bigger, and pine is suitably transferred in the front brake backguy at back brake pull bar and flywheel one ear connection place, when coaster brake rear wheel brake when general of exerting oneself, firmly front and back wheel is all braked greatly the time.(10) be the pincers locks.(4) establish the conical gear of flywheel gear in being, its constructional device is that the flywheel that overcoat has a screw thread is packed in the conical gear with negative thread that cooperates with it.

When both hands simultaneously rotate driving handle (1) forward with the rotary driving force of comparison balance under same orientation angle, owing to cancel out each other to a pair of moment that its shaft center both handlebar run-on point is produced in the driving handle two ends, thereby not only can control direction of traffic by actv., can make axle drive shaft (17) go up fixing conical gear (2) again rotates, to drive that drive link (16) upper end is fixed and to rotate with conical gear (2) ingear conical gear (15), transmission through drive link (16), the fixing conical gear (3) in its lower end is rotated, and the rotation of conical gear (3) drives the conical gear (4) that front shaft sleeve protects in the tooth box (12) that is installed in that is engaged with and rotates, and rotates thereby drive front-wheel.Car is to will so just reaching the turning purpose of f-w-d process by the difference that both hands are exerted oneself to the less side's deflection of exerting oneself when both hands rotary driving force lack of equilibrium.If when with the hands rotation drives front-wheel, drive trailing wheel with the lower limb rotation, unite driving just form upper and lower extremities, can improve the upward slope of bicycle so greatly, reach the ability of riding fast against the wind.

After both hands stop the rotation driving, because of the self-locking flywheel (13) that does not allow its counter-rotating is housed on the front wheel driving shaft (17), at this moment driving handle (1), axle drive shaft (17) just become the handlebar that supports upper limbs and control direction of traffic, and the high and low angle of handlebar can be selected according to rider's needs within the specific limits.In addition, when conical gear (4) when no longer driving front-wheel, the flywheel gear of establishing in it will dally, so normal rotation of front-wheel when not influencing lower limb independent drive trailing wheel and car body and sliding, thereby can realize automatically that upper and lower extremities replaces and unite the switching process of driving, make rider's upper and lower extremities when long-distance riding obtain alternately having a rest, the driving effect of bicycle is improved greatly.
