Abstract
The invention provides a hydraulic transmission non-motor vehicle which solves problems that transmission efficiency of a chain transmission bicycle is lower, bicycling needs great strength, and application and population of a bicycle are restricted. The hydraulic transmission non-motor vehicle has key points that a hydraulic transmission system is a closed loop system formed by an oil tank, a hydraulic pump and a hydraulic motor through a pipeline; a middle shaft serves an input shaft of a gear speed changer, an output shaft of the gear speed changer serves as an input shaft of the hydraulic pump; and the hydraulic motor is arranged near a driving shaft, and chain transmission systems are arranged on a main shaft and the driving shaft of the hydraulic motor. The hydraulic transmission non-motor vehicle has positive effects that no friction is caused nearly as the main transmission system adopts the hydraulic transmission system instead of the chain transmission systems, so that friction can be greatly reduced.
Description
Technical field
The present invention relates to a kind of unpowered vehicle (comprising bicycle, three-wheel vehicle etc.), particularly hydrostatic drive unpowered vehicle.
Background technology
In the epoch of current energy-conserving and environment-protective, bicycle is more and more subject to people's attention.Governments at all levels, in order to encourage citizen to use cycling trip, also open up bicycle designated lane more on public way.The main transmission of current bicycle mainly adopts chain transmission system, and chain transmission system is that the moment of torsion of bicycle middle shaft (being the output shaft of stretcher) is passed to axle drive shaft (being generally rear axle).The major defect of chain transmission system is: the distance between axis and rear axle is mutually far away, chain is longer, chain and sprocket wheel produce very large friction force in transmission process, can not reach best mechanical effect, particularly, when two sprocket wheels are not point-blank time, the friction force that chain and sprocket wheel produce is non-linear increase.As above-mentioned, two sprocket wheels distant, guarantees that these two sprocket wheels are very difficult point-blank, can also guarantee that two sprocket wheels are almost still impossible point-blank after using a period of time.People need to overcome these friction force by bike time, uses the bicycle driving efficiency of chain transmission system lower, and cyclist requires great effort very much, has restricted like this application, universal of bicycle.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide the hydrostatic drive unpowered vehicle that a kind of driving efficiency is high.
The object of the present invention is achieved like this: it comprises axle drive shaft (refer in front axle and rear axle or all), axis, handlebar, parking brake handle and main transmission, it is characterized in that: said main transmission is power hydraulic system the closed loop system that this power hydraulic system is comprised of pipeline fuel tank, Hydraulic Pump and HM Hydraulic Motor; Axis is as the input shaft of gear transmission, and the output shaft of gear transmission is as the input shaft of Hydraulic Pump; HM Hydraulic Motor is arranged on axle drive shaft nearby, and (with flywheel) chain transmission system is installed on the main shaft of HM Hydraulic Motor and axle drive shaft, by chain transmission system, the main-shaft torque of HM Hydraulic Motor is passed to axle drive shaft.When cyclist's pedal, drive successively axis, gear transmission, Hydraulic Pump rotation, Hydraulic Pump enters pipeline and HM Hydraulic Motor by the oil pump in fuel tank, drives HM Hydraulic Motor, chain transmission system and drive wheel rotation.
Compared with prior art, good effect of the present invention is: because its main transmission is abandoned chain transmission system, and adopt power hydraulic system, produce hardly friction force, friction force of the present invention is reduced greatly.Although the present invention has also adopted chain transmission system, but because HM Hydraulic Motor can be arranged on axle drive shaft nearby, the friction force that this chain transmission system produces makes distance and the chain of two sprocket wheels very short, is easy to guarantee these two sprocket wheels point-blank, therefore may be ignored.

Fig. 1 is structural representation of the present invention, and in figure, solid line is upper oil pipeline, and dotted line is oil return pipeline.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is the B portion enlarged drawing of Fig. 1.
The specific embodiment
Embodiment mono-: front driving type
Referring to Fig. 1 and 2, said axle drive shaft refers to front axle 4, and the closed loop system that said power hydraulic system is comprised of front upper oil pipeline 8 and front oil return pipeline 7 fuel tank 10, Hydraulic Pump 14 and front HM Hydraulic Motor arranges a check valve 11 on front oil return pipeline; Axis 20 is as the input shaft of gear transmission 15, and the output shaft of gear transmission is as the input shaft of Hydraulic Pump; Said HM Hydraulic Motor is front HM Hydraulic Motor 6, and it is arranged on front axle nearby, and chain transmission system 5 before installing on the main shaft of front HM Hydraulic Motor and front axle, passes to front axle by front chain transmission system by the main-shaft torque of front HM Hydraulic Motor.When cyclist's pedal 1, drive successively axis, gear transmission and Hydraulic Pump rotation, Hydraulic Pump enters front upper oil pipeline and front HM Hydraulic Motor by the oil pump in fuel tank, HM Hydraulic Motor, front chain transmission system and front axle rotation before driving.
Hydraulic Adjustable Speed valve 2 and hydraulic pressure oil meter 3 are set on front upper oil pipeline.Hydraulic pressure oil meter is used for showing hydraulic pressure, according to current hydraulic pressure, by regulating hydraulic pressure governor valve, carrys out pressure and the flow of regulator solution pressure motor, controls the outwards power of output of HM Hydraulic Motor, to reach optimum efficiency.
Referring to Fig. 3, the present invention is also provided with cut-out hydraulic oil pipe system at cyclist's brake lever 24, specifically: cut off hydraulic oil pipe system and comprise change-over valve 21, fork 23, change-over valve is fixed on handlebar 25, the upper end of fork is fixed on the rotating disk 26 of parking brake handle, fork withstands on the outer end of change-over valve core 211, the inner end of change-over valve core withstands on spring 212, spring fitting is on spring perch 213, the oil inlet 214 of change-over valve and one of them oil outlet oil outlet 215 that oils is connected on upper oil pipeline with series system, another oil outlet of change-over valve is that oil return oil outlet 216 is connected on oil return pipeline, the oil outlet that oils is often opened the normality into change-over valve.
During bicycle running, the hydraulic oil through regulating arrives HM Hydraulic Motor through change-over valve.In the time of need to braking, hand-to-hand grip brake lever, the turntable rotation of parking brake handle, brake cable 22 tensions that bicycle is intrinsic, the intrinsic brake system of bicycle starts, fork rotates simultaneously, pushes inward change-over valve core, change-over valve commutation, the oil outlet that will oil is closed, oil return oil outlet is opened, and directly sends hydraulic oil back to fuel tank, cuts off hydraulic circuit.
Embodiment bis-: rear-guard formula
Said axle drive shaft can also refer to rear axle 17, correspondingly, the closed loop system that said power hydraulic system is comprised of rear upper oil pipeline 9 and rear oil return pipeline fuel tank 10, Hydraulic Pump 14 and rear hydraulic motor 16, rear hydraulic motor is arranged on rear axle nearby, on the main shaft of rear hydraulic motor and rear axle, rear chain driving system 18 is installed, by rear chain driving system, the main-shaft torque of rear hydraulic motor is passed to rear axle.Other is identical with embodiment mono-.
