Each cam 31 is all fixed in stepping assembly 16, as shown in Figure 3,4.When rider is stepping on pedal 163, cam 31 is along with pedal 163 is done synchronous rotary.Meanwhile, the substantially oblong-shaped shape of each cam 31, while making cam 31 rotation, arc sheet 34 can continuous strand along being resisted against on cam 31, and without any interruption, more do not have collision sense.
As shown in Figure 3, each cylinder 33 is provided with a delivery port 331 flowing out for fluid.Delivery port 331 downstreams are provided with a check valve 6, and fluid can only be flowed out by this cylinder delivery port 331.In addition, each cylinder 33 has detachable cover 335, and is provided with in inner side the screw thread 335a that coordinates the screw thread on cylinder 33, makes 33 one-tenth sealing states of cylinder.Push rod 32 is through detachable cover 335, and piston 35 is installed in cylinder 33 with removably by this.
Pressure cylinder 5 is for storing the compression fluid from cylinder 33, when being stored in the fluid of pressure cylinder 5 and reaching a set pressure, the flow-controlling gate CV that is located at pressure cylinder 5 output opens the adjusting of the lead-in wire W by as shown in Figure 1, and the fluid having pressurizeed in pressure cylinder 5 is ordered about and flow to turbine 4.When the unexpected whole relieving of flow-controlling gate CV, bicycle can be gone out at full speed, and when flow-controlling gate CV pass hour, bicycle speed is corresponding slack-off, so, increases bicycle riding enjoyment.
As shown in Fig. 1,4, turbine 4 is to be articulated on the hind axle of bicycle with in order to drive trailing wheel.As shown in Figure 4, turbine 4 has entrance 40, outlet 42 and a plurality of blade 41 of being located on its circumference.Make every two adjacent blades 41 define a cavity, the volume of cavity be take 10c.c. as good.When the fluid having pressurizeed of being exported by pressure cylinder 5 flow to the cavity of turbine 4, the blade 41 of fluid impact turbine 4 and make turbine 4 drive the trailing wheel of bicycles, is passed to trailing wheel by kinetic energy by pedal 163 by this.
