The specific embodiment

This reciprocating type rickshaw comprises flywheel 12, sprocket crank 7, vehicle frame 5 and is contained in driving wheel, flower wheel and preceding vertical shaft 3 on the vehicle frame 5, preceding vertical shaft 3 is hinged on the vehicle frame 5, flywheel 12 is contained on the wheel shaft of driving wheel, but the ratchet of one-way movement is housed in flywheel.Flywheel 12 be about two, the rotation direction of two flywheel handle ratchet wheels is opposite.About two flywheels be mounted respectively and arranged on left and right sides at the driving wheel wheel shaft, the chain 8 by separately is connected with left and right sprocket crank 7 respectively.

Braking mechanism also is housed onboard, and braking mechanism comprises brake 14 and brake lever 4, and brake 14 is contained on the driving wheel, and brake lever 4 is connected with brake 14 by brake cable.In embodiment 1 and 2, brake 14 be can with the contacted band-type brake of driving wheel wheel shaft, in embodiment 3, brake 14 be can with the contacted pincerlike lock of driving wheel wheel rim, brake lever 4 is the brake handles that are fixed on handlebar or the vehicle frame.In addition, brake lever 4 also can be the brake pedal plate that is fixed on the vehicle frame.

(see figure 1) in embodiment 1, driving wheel are the both sides that the wheel shaft of 9, two trailing wheels 9 of two trailing wheels is hinged on vehicle frame 5 rear cross shafts respectively; Flower wheel is a front-wheel 1; Preceding vertical shaft 3 vertically is hinged on vehicle frame 5 the place aheads, and the lower end of preceding vertical shaft 3 is connected with front-wheel 1 by front fork, and the upper end of preceding vertical shaft 3 is fixed with handlebar, can drive front-wheel 1 indexing by rotating handlebar, changes the working direction of car.Left and right flywheel 12 on the driving wheel wheel shaft is connected with left and right sprocket crank 7 respectively by chain 8 separately.Left and right sprocket crank 7 is hinged on the both sides of vehicle frame 5 preceding transverse axis respectively, and is corresponding with the position of staff, pulls crank, can drive wheel by flywheel and move ahead.

(see figure 2) in embodiment 2, the position of driving wheel and flower wheel is identical with embodiment 1, just sprocket crank 7 is contained in the place ahead by the coupled driving wheel of flywheel and chain, another sprocket crank 7 is contained in the rear by the coupled driving wheel of same way as, vehicle frame 5 is provided with a block pressur plate 15, the middle part of pressing plate 15 is hinged on the vehicle frame 5, and the pommel of left and right sprocket crank 7 is hinged on the two ends of pressing plate 15 respectively.Driver's application of force of taking turns at the two ends of pressing plate just can be given flywheel with transmission of power by the up-and-down movement of crank, and vehicle is moved.

In embodiment 3, (see Fig. 3, Fig. 4), driving wheel is a front-wheel 1, left and right flywheel 12 is contained in the both sides of front-wheel 1 wheel shaft respectively, the front end of vehicle frame 5 is provided with two cambered axles, before vertical shaft 3 be hinged on the cambered axle and the front fork by the lower end is connected with front-wheel 1, at the rear of front-wheel 1, left and right sprocket crank 7 also is equipped with in its both sides, left and right sprocket crank 7 is hinged on the minor axis, and by being connected with front fork respectively with minor axis two ends bonded assembly support 16.Left and right sprocket crank 7 can play handlebar.
