Abstract
The utility model provides a non-motor vehicle with hydraulic transmission, and aims to solve the problem that the transmission efficiency of a bicycle with chain transmission is relatively low, so that bicycling is strenuous, and application and popularity of bicycles are restricted. According to the utility model, the point is that a hydraulic transmission system is a loop system which consists of a tank, a hydraulic pump and a hydraulic motor through pipelines; a center shaft is used as an input shaft of a gear transmission, and the output shaft of the gear transmission is used as the input shaft of the hydraulic pump; the hydraulic motor is arranged near a drive shaft, while a chain transmission system is arranged on a spindle and a drive shaft of the hydraulic motor. The utility model has the positive effect that the hydraulic transmission system is used as the main transmission system instead of the chain transmission system with little friction generated, so that friction generated by the non-motor vehicle with hydraulic transmission is greatly reduced.
Description
Technical field
The utility model 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 more and more is subject to people's attention.Governments at all levels also open up the bicycle designated lane in order to encourage citizen to use cycling trip more on public way.The main transmission of present bicycle mainly adopts chain transmission system, and chain transmission system is that the moment of torsion with bicycle middle shaft (being the output shaft of stretcher) passes 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 not point-blank the 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.The people need to overcome these friction force by bike the time, namely use the bicycle driving efficiency of chain transmission system lower, and the 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 purpose of this utility model is to provide the high hydrostatic drive unpowered vehicle of a kind of driving efficiency.
The purpose of this utility model is achieved in that 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 by 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, namely 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 with 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 utility model is: due to its main transmission slip a cable bar driving system, and adopt power hydraulic system, produce hardly friction force, friction force of the present utility model is reduced greatly.Although the utility model 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.
