In figure: 1-manual variable delivery hydraulic plunger fuel pump, 2-manual variable delivery hydraulic piston motor, 3-oily cylinder, 4-oil pipe, 5-bicycle body, 1-1-oil pump body, 1-2-transmission shaft, 2-1-motor body, 2-2-output shaft.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, the present embodiment comprises bicycle body 5, and bicycle body 5 comprises vehicle frame,
The stretcher place of vehicle frame is provided with manual variable delivery hydraulic plunger fuel pump 1, with reference to Fig. 2, manual variable delivery hydraulic plunger fuel pump 1 comprises oil pump body 1-1 and the transmission shaft 1-2 through oil pump body 1-1, and stretcher is positioned at the two ends of transmission shaft 1-2, and the stretcher handle of stretcher is connected with the two ends of transmission shaft 1-2; The trailing wheel center of bicycle body 5 is provided with manual variable delivery hydraulic piston motor 2, with reference to Fig. 3, manual variable delivery hydraulic piston motor 2 comprises motor body 2-1 and is positioned at the output shaft 2-2 on motor body 2-1, output shaft 2-2 is hollow shaft, output shaft 2-2 is connected with the overriding clutch of bicycle trailing wheel, the hind axle of bicycle is a major axis, hind axle passes and stretches out at the other end of motor from output shaft 2-2, trailing wheel and manual variable delivery hydraulic piston motor 2 are just connected on an axle with one heart, and frame end is fixed on the two ends of hind axle; Be connected by oil pipe 4 between manual variable delivery hydraulic plunger fuel pump 1 with manual variable delivery hydraulic piston motor 2; Also be provided with oily cylinder 3, oily cylinder 3 is connected with oil pipe 4.Oil cylinder 3 is built with hydraulic oil.
Output shaft 2-2 is equipped with adapter sleeve, and adapter sleeve is directly connected with the overriding clutch at bicycle trailing wheel center.Adapter sleeve also can be sprocket cover, and sprocket cover is meshed with the sprocket gear at bicycle trailing wheel center just can (sprocket gear and overriding clutch connect together).When manual variable delivery hydraulic piston motor 2 rotates, output shaft 2-2 and adapter sleeve just drive overriding clutch to rotate together with wheel, and car is just gone ahead.
Oil pump of the present utility model is manual variable delivery hydraulic plunger fuel pump 1, and motor is manual variable delivery hydraulic piston motor 2.By regulating two " variablees ", can realize easily converting moving velocity very reposefully on a large scale, and overcome resistance of all sizes under steam, being no matter the resistance on smooth road or when going up a slope, particularly going up resistance during abrupt slope.
When solo running road is very smooth walk very well time, be adjusted to maximum by manual variable delivery hydraulic plunger fuel pump 1 discharge capacity, manual variable delivery hydraulic plunger fuel pump 1 gets maximum oil mass to supply manual variable delivery hydraulic piston motor 2 this moment; Now the discharge capacity of manual variable delivery hydraulic piston motor 2 is then transferred to very little (turn around and only need very little oil mass).So manual variable delivery hydraulic piston motor 2 High Rotation Speed under the effect of large gauging gets up, thus bicycle is driven to run at high speed.
When bicycle to go up a slope particularly go up steeper slope time, manual variable delivery hydraulic plunger fuel pump 1 discharge capacity will be transferred to very little, and now manual variable delivery hydraulic plunger fuel pump 1 (refers to pedal force) and then produce the oil of very high pressure under identical application force; And now the discharge capacity of manual variable delivery hydraulic piston motor 2 is transferred to very large, high pressure oil enters the manual variable delivery hydraulic piston motor 2 of huge discharge, just very large driving torque is produced, thus the rolling resistance of the sliding force overcome when car goes up a slope and traveling, make the grade (now the speed of car has also slowed down) like a cork.
Propulsive effort of the present utility model also can be transferred to larger, and just limited as the adhesive ability of the trailing wheel of drive wheel, trailing wheel can skid.If the back seat of car sat individual again or carry upper weight.Due to the increasing of trailing wheel adhesive ability, bicycle can climb steeper slope.
When people limited force and to pedal speed (referring to the pedal force of people and foot-operated rotating speed), by regulating two " variablees ", easyly can realize bicycle and advancing at a high speed, improve the ability of climb very steep slopes and load-carrying.
The utility model is faster than existing any one bicycle riding speed, and hill climbing ability is stronger, and load carrying ability is larger.And speed change, variable force are stepless transformations, transition is very steady.It is all untouchable that this is that other any bicycle comprises the mountain bike of variable-ratio.When changing the discharge capacity of manual variable delivery hydraulic plunger fuel pump 1 and manual variable delivery hydraulic piston motor 2, it handles also simple especially, easily.
Hydraulic oil is the working medium of manual variable delivery hydraulic plunger fuel pump 1 and manual variable delivery hydraulic piston motor 2, and thus, manual variable delivery hydraulic plunger fuel pump 1 and manual variable delivery hydraulic piston motor 2 can be lubricated fully.Not only long service life is also simultaneously the very steady place of their work.
Whole power hydraulic system carries out closed working cycle with regard to manual variable delivery hydraulic plunger fuel pump 1 and manual variable delivery hydraulic piston motor 2 being linked together by oil pipe 4.As long as oil pipe 4 joint connects, it is reliable to be sealed, entirety just seems clean especially succinct.Unlike chain, sprocket-type bicycle, with long afterwards, chain can loosen, easy chain-taking, also the easy card bottom of s trouser leg.
The oil pump that the utility model is selected and HM Hydraulic Motor all adopt plunger tpe, this is because plunger tpe is most effective (comparing vane type and gear type etc.), efficiency can reach 95%.
Infinite variable speed hydraulic efficiency pressure system of the present utility model also can be used for three-wheel vehicle, and vehicle for disabled person (foot-operated, manually), play on car and little pleasure-boat.
Those skilled in the art can carry out various modifications and variations to the utility model embodiment; if these amendments and modification are within the scope of the utility model claim and equivalent technologies thereof, then these revise and modification also within protection domain of the present utility model.
The prior art that the content do not described in detail in specification sheets is known to the skilled person.
