Embodiment
As shown in the figure, moving boosting mechanism bicycle of a kind of 4 wheel driven and three-wheel vehicle, it is characterized in that comprising vehicle body servodrive mechanism, vehicle body lever servodrive mechanism, lever tap servodrive mechanism, its vehicle body servodrive mechanism forms the moving compound gear 14 of 4 wheel driven by unidirectional power transmission gear, chain drum gear 15, and compound gear 14 all is fixed in same axle mounting on vehicle body frame 24; Vehicle body lever servodrive mechanism is made up of load-bearing lever 18, balance pivot 16, load bearing spring 17, one, two drives power-assisteds 1,3 chains one end and be individually fixed on the load-bearing lever 18, the other end is individually fixed on first and second gear of the moving compound gear 14 of 4 wheel driven, connecting one, two coil tension springs 2,4,, two coil tension springs, 2,4 its other ends respectively by the gear rear end is installed in respectively on the vehicle body frame 24; Lever tap servodrive mechanism is made up of direction lever 23, leading lever 11, be provided with leading balance pivot 9 between it, three, the moving power-assisted chain 5,7 of 4 wheel driven is located at leading balance pivot 9 front and back ends respectively, be loaded on respectively by leading directional wheel 10, vehicle body directional wheel 10 on third and fourth gear of the moving compound gear 14 of 4 wheel driven, by the gear rear end respectively with three, the moving coil tension spring 6,8 of 4 wheel driven is connected, three, four coil tension springs, 6,8 its other ends are individually fixed in vehicle body frame 24.Tap lever 11 is provided with balance spring 25, is provided with slide link 12 between its leading lever 11, and slide link 12 is provided with parking anchor 13, and during parking, the other end of parking anchor 13 is inserted on the wire loop on the vehicle body.Slip cushion 19 before and after load-bearing lever one end is provided with is equipped with the horse formula that jumps and drives pin link plate 20 on it.
Show among the figure, when driving the utility model, check brake earlier, its wheel is fixed, vehicle body load-bearing lever 18 is in zero heavy burden state at this moment, after the people takes car, grasp direction, releasing of brake, vehicle body load-bearing lever 18 and load bearing spring 17 press down because of people's weight, vehicle body load-bearing lever 18 resistance arms upwarp, and drive power-assisted chain 1, one driving power-assisted chain 1 transmission power-assisted immediately gear thereby spur first, i.e. first actuating device power-assisted success, because of vehicle under steam by the road surface, the vibration that vehicle itself produces and the amphicheirality of spring, load bearing spring 17 will ceaselessly stretch, when load bearing spring 17 is upheld, be that vehicle body load-bearing lever 18 power arms rise, second drives power-assisted chain 3 will spur second drive transmission generation power-assisted, circulate one repeatedly with this, two assistant force drive device just produce power-assisted continuously and help vehicle and advance.
Make to tramp with one's feet when travelling, because people's center of gravity is shifted to pedal, vehicle body load-bearing lever 18 will float because of easing off the pressure, and promptly two drives power-assisted chain 3 generation power-assisteds.Otherwise, when the gravity center of human body is fallen back on the vehicle body load-bearing lever 18, then one drive power-assisted chain 1 generation power-assisted, circulate with this, reached laborsaving power-assisted purpose, power-assisted will produce at any time.When using the horse formula that jumps to drive pin link plate 20, the people stands up, and bends over, and both feet firmly one are squatted together, and vehicle also can drive under the power-assisted one, two and advance.If be used leading lever 11 power-assisteds, effect will be more obvious.Because one, two power-assisted drivings can make the vehicle body lever ceaselessly rise and fall, drive so be named the horse formula that jumps.The driver will have the sensation as a kind of the riding.
If when using leading lever actuated power-assisted simultaneously, will produce very strong driving force under steam, vehicle will advance at utmost speed.Both hands are held tap and are pressed down simultaneously during driving, and three power-assisteds drive then through-coupling power-assisted chain drum, and when both hands were held tap and pressed down, people's center of gravity moved on the tap, the vehicle body lever come-up that eases off the pressure again, and two drive and will produce great power-assisted simultaneously again.Otherwise, tap is carried simultaneously, then 4 wheel driven moves power-assisted through-coupling power-assisted chain drum, and people's center of gravity is returned again on the vehicle body lever, and a power-assisted drives and produces power-assisted again simultaneously, circulates repeatedly with this.
Pedal driving chain 21 is behaved and is tried hard to recommend actuation mechanism promotion chain; Servodrive chain 22 is the moving servodrive mechanism of 4 wheel driven chain.
