The running speed and the climbing ability can be raised, the degree of fatigue of a rider can be reduced, the whole body of the rider can obtain balanced exercise and training, and the utility model is favorable to strengthen and build the body.

Description

The trick double driving bicycle

The utility model relates to bicycle, specifically a kind of trick double driving bicycle.

The existing bicycle that generally uses drives wheel disc by pedal and travels by chain and the rotation of flywheel drive rear wheel.Owing to only rely on the lower limb of human body that propulsive effort is provided, do not give full play to the effect of hand and arm, the raising of the propulsive effort and the speed of a motor vehicle is restricted, its hill climbing ability is poor, the fatiguability of riding on the way far away.And, when taking a bus instead of walking for a long time,, also be unfavorable for body-building because human upper limb can not get movable fully and takes exercise from the angle of health.

The purpose of this utility model is the problems referred to above at existing ordinary bicycle existence, and provide a kind of hand-drive separately or pin to drive or the two bicycle driven of trick, to improve bicycle driving power and moving velocity, strengthen its hill climbing ability, reduce cyclist's degree of fatigue, help healthy.

For achieving the above object, the technical scheme of being taked is: a kind of trick double driving bicycle is provided, it includes vehicle frame, be arranged on the vehicle seat of top, vehicle frame rear end, be configured in the front vehicle fork of vehicle frame front end, the handlebar that is arranged on vehicle frame front end top and joins with front vehicle fork, be installed in the front vehicle wheel of front vehicle fork lower end, be connected the rear vehicle fork of vehicle frame rear end, be assemblied in the rear vehicle fork lower end rear wheel and by the pedal roulette that is arranged on the vehicle frame lower end, be installed in the flywheel on the rear vehicle shaft and be assemblied in wheel disc and flywheel on the pedal actuating device formed of chain.One hand-drive flywheel is installed on the wheel shaft of front vehicle wheel, be equipped with proficiency on the top of front vehicle fork and drive wheel disc, be equipped with chain on its hand-drive flywheel and the wheel disc, be respectively arranged with the end in the both sides of hand-drive wheel disc with the fixing crank of wheel disc axle, the other end of two cranks is hinged respectively and is connected to pull bar, the upper end of each pull bar is hinged respectively and is connected to the hand-drive lever, the nearly rear end of two hand-drive levers is installed on the fulcrum shaft that is fixedly set on the handlebar, is equipped with the activation lever handle at the front end of each hand-drive lever.

This trick double driving bicycle is compared with existing ordinary bicycle, has following advantage:

1, travel, and increased propulsive effort, can improve the hill climbing ability and the moving velocity of bicycle greatly owing to but trick drives simultaneously.

2, drive because of being used alternatingly upper limbs and lower limb, can improve cyclist's moving condition greatly, reduce cyclist's degree of fatigue.

3, owing to make the whole health of cyclist obtain balanced motion and exercise, for the person that do not take a bus instead of walking for a long time, help body-building, diseases prevention is prevented or cure a disease.

Accompanying drawing is this trick double driving bicycle structural representation.

Below in conjunction with drawings and Examples this bicycle is described further:

Provide as accompanying drawing, this bicycle has vehicle frame 1, is provided with vehicle seat 2 above the vehicle frame rear end, and front end is equipped with front vehicle fork 10, and the lower end of front vehicle fork is equipped with front vehicle wheel 8.Linking to each other above the vehicle frame front end and with front vehicle fork is connected to handlebar 15, is connected with rear vehicle fork 3 in the rear end of vehicle frame, in the lower end of rear vehicle fork rear wheel 4 is installed.Be installed in the pedal roulette 7 of vehicle frame lower end and be installed in the flywheel 5 on the rear vehicle shaft and constitute the pedal actuating devices with the driving chain 6 of its cooperation.One hand-drive flywheel 9 is installed on the wheel shaft of front vehicle wheel, drive wheel disc 12 and dispose driving chain 11 on the other hand in the assembling of the top of front vehicle fork, the crank 17 that is fixedly linked with its dish axle is set respectively in the both sides of wheel disc 12, the other end of each crank 17 is hinged pull bar 16 respectively, the upper end of each pull bar 16 is hinged hand-drive lever 14 respectively, the nearly rear end of each lever 14 is installed on the fulcrum shaft that is fixedly set on the handlebar 15, front end at each lever 14 is provided with activation lever handle 13, forms manual driving device.

This bicycle can be held handlebar, utilizes pedal to drive car body, and it is equally ridden with ordinary bicycle.And be arranged at handlebar and make alternately following by the handle of two lever front ends of midway location and both hands and press roping when moving when holding, its lever will be that fulcrum moves up and down the rear end with the fulcrum shaft on the handlebar, and by pull bar and the rotation of crank drive manual drives wheel disc, driving the hand-drive flywheel through driving chain again rotates, and then drive the front vehicle wheel rotation, realize the hand-drive bicycle running.
