Background technology
Advantages such as unpowered vehicles such as bicycle, manual tricycle, hand barrow are flexible because of it, price is low are generally used in people's life.Unpowered vehicle can be taken the people, again can loading, and be people's go off daily, the important tool of transporting goods, but under the situation of or upward slope heavy in loading, can consume a large amount of muscle power of user, and a people's strength often is difficult to omnidistance the driving, can causes the manpower waste and be equipped with many people.Deficiencies such as in addition, speed is slow, efficient is low also are the more widely used key factors of restriction unpowered vehicle.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of laborsaving hydraulic pressure of unpowered vehicle efficiently limitless automatic speed changing work-saving device.
The technical solution of the utility model is as follows: the limitless automatic speed changing work-saving device of a kind of unpowered vehicle hydraulic pressure, by propulsion source, variable capacity oil pump, hydraulic reservoir, component set-up such as change-over valve and oil motor, wherein propulsion source control variable oil pump running, the oil inlet of described variable capacity oil pump is connected with hydraulic reservoir by oil pipe, the oil outlet of variable capacity oil pump joins by the oil inlet of oil pipe and change-over valve, the oil outlet of this change-over valve is connected with the oil inlet of oil motor by oil pipe, the oil outlet of described oil motor joins by the oil return import of oil pipe and change-over valve, and the oil return of change-over valve outlet is connected with hydraulic reservoir by oil pipe.
Adopt above technical scheme, propulsion source, variable capacity oil pump, hydraulic reservoir, change-over valve, oil motor and be connected oil pipe and form hydraulic control system, integral installation is on unpowered vehicle, and the output shaft of oil motor is connected with the wheel shaft of unpowered vehicle by transmission device.When propulsion source did not start, unpowered vehicle can freely be advanced according to traditional approach; After propulsion source starts, variable capacity oil pump is for unloaded substantially, seldom power consumption is obstructed when non-power car travels, when needing power-assisted, and change-over valve control presssure oil flows to oil motor, the output shaft of oil motor is rotated by the wheel shaft that transmission device drives unpowered vehicle, this moment hydraulic control system increased pressure, the variable capacity oil pump flow that diminishes improves pressure, increased the output torque of oil motor, made unpowered vehicle slow down moving velocity; When the unpowered vehicle resistance to motion reduced, the pressure of hydraulic control system reduced, and variable capacity oil pump strengthens oil mass, unpowered vehicle fast running.This shows that the utility model can be saved manpower, effectively improve the speed and the load-carrying capacity of unpowered vehicle.
For simplified structure, the convenient installation and control, above-mentioned propulsion source is oily machine or motor, and described variable capacity oil pump is installed on the output shaft of this oil machine or motor; Above-mentioned change-over valve is " H " type four-way change-over valve.
Beneficial effect: the utility model drives variable capacity oil pump with the miniwatt propulsion source, produce pressure oil, by change-over valve control pressure oil is transferred to oil motor, make the different rotating speed of oil motor output, different moments of torsion, drive unpowered vehicle with the fastest speed, maximum load-carrying capacity, reach laborsaving purpose efficiently, have reasonable in design, implement easily, characteristics such as good reliability, range of use are wide, on dissimilar unpowered vehicles, all can use.
