Description

The micro hydraulic transmission is bicycle speed-increased

Advantage of the present invention and purposes:

The a pair of micro hydraulic transmission that the invention belongs to the transportation means type is bicycle speed-increased, particularly this car can replace that bicycle uses, its volume is little, in light weight, easy to carry, 28 centimetres of its total lengths, wide 10 centimetres, high 13 centimetres.Every leg is worn a bicycle, and the people stands in the motion of marking time up and down on the stretcher, along with the speed in foot-operated step is regulated the travel forward size of speed of bicycle.Determine that with the angular dimension that both feet twist to the left and right bicycle turns to the angular dimension of (turning round).Bicycle is provided with the automatic guidance lock.

The objective of the invention is to carry for the travelling personnel are contained in the hand baggage, can be through the transportation means of making speedup on the pin at any time, general speed of the present invention is 10～15 kilometers, and it is compared with bicycle, reduce labour intensity and be about 30 percent.

The object of the present invention is achieved like this: the pressure of bicycle on stretcher, pass on the piston by piston rod.Piston in oil cylinder, promote hydraulic oil through the oil outlet of oil cylinder, enter in the HM Hydraulic Motor chamber.The motion that the pressure of hydraulic oil promotes blade movement, blade promotes rotor shaft motion.Fixed two rubber wheels in rotor shaft two ends, the rotation of rotor shaft order about rubber wheel and rotate, and cause the people to stand in bicycle and are travelling forward.

Trailing wheel of the present invention has only one, and the position is in the center of two front-wheels, and the lines of front and back three wheels kiss the earth are the positions of equicrural triangle, and it is being controlled, and human body stands in swing on the bicycle and application force, the trailing wheel facing upward, crouch turn to along with turning to of pin.The hind axle two ends are cemented in respectively on the fork mouth of back vent plate.Back vent plate upper end is provided with pipe spreader, beam barrel, sleeve pipe, slide bar and the retracing spring of steering hardware.Following, slide bar and sleeve pipe that slide bar upper end is cemented in stretcher move up and down, and try hard to recommend moving slide bar, sleeve pipe and the beam barrel of the swing of stretcher are swung, and are ordering about trailing wheel and are turning to along with turning to of front-wheel.

The realization of control sluice of the present invention: be lock core, restrictor bar and a flashboard, when two bicycles courts are drawn close together, two flashboards head on mutually, restrictor bar and the lock core that promotes separately advances in oil cylinder respectively, it is sealing oil inlet, stop hydraulic oil in HM Hydraulic Motor, to flow, thereby controlling the rotation of rotor shaft.

The realization that pulls control sluice of the present invention: be an aperture is bored in the restrictor bar outer end, be installed with a ring in the hole, be enclosed within on the ring, at the lateral surface that rope is instead arrived ring, with portable rope with rope.When the needs lock was lived bicycle, both hands rope of exerting oneself made restrictor bar promote the lock core and seals oil inlet, stops hydraulic oil to flow, thereby is controlling the rotation of rotor shaft.

Concrete structure of the present invention is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the section-drawing that proposes the bicycle speed-increased device of micro hydraulic transmission according to the present invention.Describe the details and the service condition of the concrete device that proposes according to the present invention in detail below in conjunction with Fig. 1.

According to the principle in the hydraulic actuator, design a kind of new blade formula HM Hydraulic Motor transmission bicycle.Pin is consolidated in above the stretcher 1, and the energy of riding down passes to piston 4 by piston rod 2, passes to hydraulic oil from piston 4, and hydraulic oil enters in the sliding-vane motor chamber by the oil outlet of oil cylinder 19, promotes blade 25 motions.Blade 25 is enclosed in the groove of rotor core at rotor shaft 23 centers, has a wire spring (accompanying drawing is not annotated explanation) to promote blade 25 and makes centrifugal motion, and when any one blade 25 moves to when cutting oil clot 24, these blade 25 compression wire springs are done entad motion.The both sides of blade 25 are respectively equipped with rotor plate (not drawing among the figure), rotor bolt 26 is tight with rotor plate and rotor core cangue, rotor core garden week, the baseplane contacted with a section oil clot 24, and section oil clot 24 stops the hydraulic oil in the motor cavity, makes the arrow direction of hydraulic oil by Fig. 1.Rotor core is to be consolidated in the rotor shaft 23 that the front wheel spindle center is formed, and the two ends of rotor shaft 23 are the rubber wheel of fixed one 10 cm diameter respectively, and this takes turns promptly is the front-wheel 21 of bicycle.Fluid power promotes blade 25 motions, makes rotor shaft 23 rotations, orders about bicycle and travels forward.A rail circle 27 and a section oil clot 24 are fixed in stator-motor body 28 with pilot pin 22, and the pressure of motor body acts on the upper surface of rotor plate, and the rotor plate outside is provided with oil seal plate (not drawing among the figure).

See that from figure arrow is the hydraulic oil travel direction, hydraulic oil enters piston 4 upper spaces in the oil cylinder 19 through the oil inlet of HM Hydraulic Motor chamber, oil duct and oil cylinder 19.When pin and stretcher 1 upwards lifted, cylinder inner spring 18 promoted pistons 4 upward movements.Be subjected to the effect of bicycle coherence power, rotor shaft 23 still rotates, and makes the hydraulic oil in the HM Hydraulic Motor chamber be discharged to piston 4 upper spaces, and this hydraulic oil enters the lower space of piston 4 by the oil through of piston 4.When pin stepped down, piston 4 moved downward, and lock supporting plate 16 is subjected to spring 17 upwards to head on the effect of power, and lock shrouding 16 is sealing the oil through of piston 4, the hydraulic oil that makes piston 4 lower space not return piston 4 on space not.When piston moved down, it was promoting hydraulic oil and is discharging through oil outlet, and hydraulic oil promotes blade 25 motions.

Two beam slabs 5 are welded on oil cylinder 19 respectively and beam barrel 9(is shown in Figure 1), beam barrel pack into up and down sand bowl, sand grains, lower gear (annotating explanation among the figure), cover female 8 is cemented in the upper end of pipe spreader 10 with screw thread, and sleeve pipe 7 is enclosed in the pipe spreader 10 and moves up and down.Slide bar 6 upper ends are cemented in below the stretcher 1, and its lower end is enclosed in the sleeve pipe 7 and moves up and down.Back vent plate 11 is welded on the both sides of pipe spreader 10, the mouth of back vent plate 11 with nut fastening rear axle 14, the trailing wheel of forming with rear axle 14, bearing 13, trailing wheel adhesive tape 12.The pendulum angle that is limiting trailing wheel with retracing spring 15 is 90 °, and trailing wheel is to roll on the ground along with the rotation of front-wheel.

Fig. 2 is that A-A is put twice section-drawing among Fig. 1, a pair of bicycle corresponding brake cylinder 32 be to be welded near the hydraulic ram 19 top oil inlets, the lock plug that has lock spring 33 to head on lock core 31 in the brake cylinder 32 outwards moves, lock core 31 outer faces and restrictor bar 35 are tightened with screw thread, restrictor bar 35 is enclosed in can be reciprocating in the brake cylinder lid 34, restrictor bar 35 end faces fastening flashboard 29.When both feet come closer, left and right sides flashboard 29 is headed on mutually or when pulling rope (this figure does not draw), restrictor bar 35 head on lock core 31 inwardly motion sealing oil inlet, make the hydraulic oil stop motion, thereby controlling the motion of bicycle.

When two flashboards 29 leave, be subjected to lock spring 33 externally to head on the effect of power, promote outwards motion of lock core 31, oil inlet is left in the end of lock core 31, and hydraulic oil is passed through at the oil inlet place, and bicycle gets final product work.
