The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment
Be illustrated in figure 1 as structural representation of the present utility model; A kind of new ideas comprise front-wheel, trailing wheel, vehicle frame, transmission device without the explosion-proof bicycle of chain dragline-transmission, and transmission device is installed on the vehicle frame; As shown in Figure 2: described transmission device comprises disc cam 1, fork 2, flywheel 5, rigidity rope 4, elastic threads, fork axle, pedal spindle 3, fixed pulley, described disc cam 1 is installed in the vehicle frame both sides, disc cam 1 is installed on the vehicle frame by pedal spindle 3, fork 2 is installed in the vehicle frame both sides, fork 2 is installed on the vehicle frame by the fork axle, flywheel 5 is installed on the trailing wheel by the flower-drum symmetry, disc cam 1 adopts cam to be connected with fork 2, also connects fixed pulley by hinge bolt on the top of each fork 2;
Described in vehicle frame one side, rigidity rope 4 one ends are fixed on the nadir of flywheel 5 and cw twines the fixed pulley that two circles walk around on the fork 2 after above and is fixed on the vehicle frame, and elastic threads one end and rigidity rope are fixed on flywheel 5 same points and conter clockwise rear and rigidity rope 4 more than a circle and are fixed on same position place on the vehicle frame;
Described at the vehicle frame opposite side, rigidity rope 4 one ends are fixed on the vertex of flywheel 5 and conter clockwise twines the fixed pulley that two circles walk around on the fork 2 after above and is fixed on the vehicle frame, and elastic threads one end and rigidity rope 4 are fixed on flywheel 5 same points and cw rear and rigidity rope 4 more than a circle and are fixed on same position place on the vehicle frame.
