The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:

Fig. 1 represents overall structure of the present utility model.Car has vehicle body 1 to coat outward, and the vehicle body transversal surface is a similar round, sees Fig. 6-Fig. 8 for details.Profile is seen Fig. 1, for the high continuous flow line type structure in preceding short back, its objective is the air resistance that reduces driving.Body forward structure has car light 2, but postmedian has the skylight 3 of sliding, and the rainy day is closed window, and all the other times are opened the skylight to ventilate.Body top section is a hyaline layer 4, and the bottom is a non transparent layer 5.

Transmission device is seen Fig. 1 and Fig. 2.Front-wheel 6 is connected with front fork 7, and there is bevel gear 8 on the front fork top, and the front fork top has 9 on support propping up angular wheel shaft 10.The transmission fork 15 of drive sprocket 12, pedal 13 and band handlebar 14 is arranged on the transmission shaft 11, have bevel gear 16 and frame propping up the support 9 of angular wheel shaft 10 on the transmission fork.Staff steered vehicle handle drives front-wheel by two pairs of bevel gear pairs to drive front fork, to grasp direction of traffic by bus.Flywheel 20 and energy storage spring-wheel 21 are respectively arranged on tween drive shaft 18 and the rear axle 19.The rider is reclining to pedal, and drive sprocket 12 drives tween drive shaft by chain 22 and flywheel and rotates, and the hinge wheel 23 of other side of tween drive shaft drives rear axle by chain and flywheel and trailing wheel 24 rotates, and car to overtake.Owing to be to recline to pedal, left foot and right crus of diaphragm all are difficult in 180 ° of scopes with all strength to pedal, be that each pin all has in the narrow radian scope and pedals not energetically, at this moment, just become kinetic energy by the potential energy that is stored in the energy storage spring-wheel, help tween drive shaft to rotate forward, with to since left and right sides pedal not energetically that section arc carry out power-assisted.

Servomechanism is that the structure of energy storage spring-wheel 21 is seen Fig. 5, and an end of sheet spring 25 is fixed on the axle sleeve of the axle sleeve of tween drive shaft 18 and rear axle 19, and end is fixed on the shell 26 in addition.Energy storage spring-wheel shell on the rear axle 19 has tooth 17 outward.

Referring to Fig. 1-Fig. 4, rear axle is put on the shelf and is propped up an after-frame 27 and 28, and after-frame props up and is supported by frame 29, and after-frame and body tail constitute the back railway carriage or compartment 30 of depositing with the car article.After-frame 28 by last pipe 31 and down pipe 32 constitute, in spring 33 is arranged, human body is played the damping, buffering effect.Tooth bar 34 is arranged by the after-frame 27, be meshed with 21 shells 26 of energy storage spring-wheel on rear axle tooth 17 outward.In the driving way, when human body, vehicle body and after-frame weight were depressed downwards by two after-frames, the tooth bar 34 of after-frame 27 drives teeth 17 and energy storage spring-wheel 21 rotates with energy storage, and this energy storage can play the power-assisted effect to overtake to of the present utility model, reaches the purpose of efficiently travelling.

The utility model contrast prior art has following advantage: owing to be to adopt the formula of lying behind the car driver that is similar to Drive ride comfort; Vehicle body can rainproof and winter protection; Owing to adopt energy storage spring-wheel on axis and the rear axle, use gravity and Power is carried out power-assisted to overtake to pedal, can improve travel speed.
