Each transmission gear is done periodic running in clockwork spring energy output procedure, so the miniature gears that the energy unlocking wheel 7 of going barrel drives the flower wheel 8 that is meshed with it is done accelerated movement, thereby the crank wheel that is meshed with the flower wheel big gear wheel 9 rotates, crank drives crank rocker 10 and does reciprocating action under the rotation of crank wheel, thereby promote the right pistons work of hydraulic actuating cylinder 11, therefore this structure has reduced gear forces, promptly is used for piston with less masterpiece.

As shown in Figure 1, 2, piston is done reciprocating action under the effect of crank rocker 10, when piston was moved to the left, compressing hydraulic oil flowed left, and hydraulic oil is by the pressure oil pipeline time, impact the valve block that is arranged in the valve 32 that communicates with fuel tank above this passage by oil pressure on the one hand, it is closed, thereby cut off getting in touch between oil cylinder and the fuel tank 33, guarantee that hydraulic oil has crunch and is injected in another oil cylinder, the promotion left piston is moved to the left, and the spring of also oppressing simultaneously on the piston rod shrinks; When piston under the effect of crank wheel 9, when doing travelling backwards to the right, valve is drawn back by suction, realize that the repairing purpose simultaneously, under action of the spring and the dirty cylinder to the right of oil return suction, such crank motion drives the crank wheel 13 that links to each other with the left piston bar of hydraulic actuating cylinder and does period run the hydraulic oil of a left side in the oil cylinder equally, thereby the flywheel 14 that drives bicycle is done and is clockwise rotated, and reaches to drive the requirement that trailing wheel advances.The flywheel 14 of bicycle has two groups of teeth, and wherein one group of mountain chain bar links to each other with floral disc, rides when advancing so rely on separately, and servomechanism can not link.

As shown in Figure 3, handlebar is provided with and stirs backguy handle 15, the backguy handle is connected by the end of steel rope 16 with the lever 17 that is arranged on the bicycle middle shaft position, the other end of lever 17 acts on the bicycle middle shaft 18, bicycle middle shaft 18 kinks are in axle sleeve 19, and be provided with retracing spring 20 at axis one end, floral disc is fixedly mounted on the axle sleeve 19.When starting is travelled, can at first stir backguy handle 15, pulling steel rope 16 drives the lever 17 compressing axis that rotate around fulcrum and axially pushes, it is compression reseting spring 20, the tooth 3 that screws on the floral disc is meshed with the clockwork spring tooth 6 that screws on the going barrel, when then doing the cruising action, in the process that car advances, finish the clockwork spring work that screws very soon.After the storage of clockwork spring energy is full, dial haulback handle 15, floral disc separates with the tooth that screws of going barrel, and then clockwork spring releases energy.
