Fig. 1 is the whole assembling of a three-wheel vehicle scheme drawing.

Fig. 2 is the anterior scheme drawing of structure working principle.

Fig. 3 is a structure working principle rear portion scheme drawing.

Above-mentioned number in the figure is described as follows:

The 1-pin turns, 2-axis, 3-eccentric link, 4-bearing pin, 5-plunger oil suction pump, 6-oil pipe, 7-check valve, 8-filtering net, the 9-fuel tank, 10-hydraulic directional control valve, 11-pressure charging valve, 12-working thrust oil cylinder, the 13-vehicle frame, 14-link rod, 15-crank, 16-dead axle, the 17-big gear wheel, 18-flywheel-type gear, 19-friction disc, 20-drum, the 21-wheel, 22-housing, 23-eccentric wheel, the eccentric overcoat of 24-.

Be that the utility model adjoint is described in further detail below:

Referring to Fig. 1, assembling eccentric wheel 23 on the axis 2 of tricycle frame 13, eccentric wheel 23 peripheries are assembled eccentric overcoat 24 by steel ball, and the eccentric link 3 on the eccentric overcoat 24 is squeezed into pressure oil in the housing 22 by plunger oil suction pump 5, and drive wheels 21 is advanced again.Referring to Fig. 2, the piston of the eccentric link 3 usefulness bearing pins 4 assembling plunger oil suction pumps 5 on the eccentric overcoat 24, oil suction pump 5 delivery ports connect hydraulic directional control valve 10, plunger oil suction pump 5 input ports connect fuel tank 9 through oil pipe 6, check valve 7, filtering net 8, automatically realize the change-over valve 10 output connection bidirectional piston pressure charging valves 11 of commutation by the pressure variation of hydraulic pressure, realize exporting higher pressure oil with this, its supercharging multiple is by the ratio decision of the effective working area of the big small end of pressurized cylinder.The former three times of pressure oils to five multiplication of voltage power of pressure charging valve 11 outputs are supplied with working thrust oil cylinder 12 through hydraulic directional control valve 10.Referring to Fig. 3, working thrust oil cylinder 12 pistons connect link rod 14, crank 15 with bearing pin 4, and crank 15 other ends are assemblied in big gear wheel 17 both sides with dead axle 16, and the link rod 14 here also can save, and working thrust oil cylinder 12 pistons are linked to each other with crank 15.Big gear wheel 17 is meshed with flywheel-type gear 18, the gear 18 of unidirectional transmission be assemblied between the wheel 21 the axle on, here also can adopt such structure, a pair of crank 15 outputs one end is assemblied in eccentric outer putting, applying mechanically ball (being steel ball) outside eccentric is assemblied on the eccentric wheel, eccentric wheel is fixed on the axle of wheel 21, and this similar is in the axis drive mechanism.Also assemble friction disc 19 and drum 20 on the axletree, realization is slowed down and brake by the manual control pulling force.In order to work effectively and to reduce volume, whole thruster, comprise that hydraulic directional control valve 10, pressure charging valve 11, working thrust oil cylinder 12 and gear 17,18 all are assemblied in the housing 22, wherein big gear wheel 17 and flywheel-type gear 18 structure that is meshed also can adopt two sprocket wheels to realize by the chain gear structure.Whole principle of work is foot-operated by pedal, making bipod turn 1 relatively rotates, promote plunger oil suction pump 5 crank motions, make pressure charging valve 11 back and forth export higher pressure oil in an orderly manner, through working thrust oil cylinder 12 working in reciprocating mode, drive big gear wheel 17 continuous rotation, drive flywheel-type gear 18 and rotate, drive two wheels 21 by axle and advance.

Advantage of the present utility model and effect are as follows:

1, owing to adopt hydraulic oil as the work medium, thus stable drive, and pass through Supercharging has improved driving force, has alleviated human body work transportation intensity, has reached the labour-saving Purpose.

2, because this structure improves driving force, thus loading capacity and conevying efficiency improved, Improved remote transport capacity.

3, owing to adopt the hydraulic oil conduction, so noiselessness is free from environmental pollution, maintenance also More convenient, 7.5～10 kilometers of car scooters/time.

4, avoid original heavy duty to cause the phenomenon of off-axis chain rupture, improved shipping mass And speed.

5, owing to employing hydraulic oil conducts, thus stable performance, and period of service is long, need not more change oil, to a certain extent energy savings.
