Description
Technical field
The invention belongs to automobile technical field, be specifically related to a kind of manpower and drive the hydraulic power car.
Background technology
Bicycle is a kind of manpower transportation, and it is by the sprocket wheel of people's pedal force by machinery people's pedal force to be transformed into circumferential force, drives the bicycle rear rotation by chain transmission and sprocket wheel conversion and advances.In the conversion and transmittance process of power, utilize sprocket wheel and chain gear, this transfer mode useful work only accounts for about 20% of acting.Bicycle often runs into the situation of ascents and descents, needs moment of torsion bigger during upward slope, and the descending moment of torsion is less, the Regular Bicycle transmission speed ratio is fixed, and tramples inconvenience, several fixing speed ratios of the change that mountain bike can only be limited, but structure is complicated, and reliability is not high.Electrical Bicycle, electric three-wheel developed rapidly and popularized in recent years, it drives the motor that is positioned on the trailing wheel by storage battery and advances, but technical bottlenecks such as the capacitance of storage of storage battery, service life and electrical efficiency are restricting the battery-driven car development, exist maintenance cost higher, the continuous limited problem of operating range, a large amount of waste and old storage batterys are handled and have been increased social cost.
Summary of the invention
For solving the problems referred to above that prior art exists, the object of the present invention is to provide a kind of compact conformation, volume is little, and cost is low, and transformation of energy is convenient, realizes that the manpower of electrodeless variable-speed drives the hydraulic power car.
For achieving the above object, the technical solution used in the present invention is: this manpower drives the hydraulic power car, has actuating unit, it is characterized in that: described actuating unit has fuel tank and the thick oil filter that is connected successively by oil pipe, the manpower pump, check valve, the outlet of check valve is communicated with the first two position three-way valve oil inlet simultaneously, the two position two-way valve return opening, the second two position three-way valve second place oil inlet, the first two position three-way valve primary importance oil outlet connects the bidirectional variable oil motor, the first two position three-way valve second place oil outlet is communicated with fuel tank, the bidirectional variable oil motor drives drive wheel, the outlet of bidirectional variable oil motor connects the 3rd two position three-way valve oil inlet, the 3rd two position three-way valve second place oil outlet connects the two position two-way valve oil inlet by oil pipe, the second two position three-way valve oil inlet is communicated with the 3rd two position three-way valve first oil outlet by oil pipe, the second two position three-way valve oil outlet connects adjustable throttling successively, thin oil filter, the outlet of thin oil filter is communicated with fuel tank.
Described the 3rd two position three-way valve second place oil outlet also is communicated with energy storage.
Described manpower pump and check valve are a plurality of.
Adopt the beneficial effect of technique scheme: this manpower drives the hydraulic power car and scrunches the manpower pump by manpower, converts kinetic energy to the hydraulic pressure energy, with the liquid transfer energy, can convert hydraulic pressure to gyroscopic movement with the bidirectional variable oil motor, exports by drive wheel.Concrete working process: after the manpower pump rotates, power oil sucks the manpower pump through oil pipe, thick oil filter, after first two position three-way valve P mouth → A mouth enters the bidirectional variable oil motor, enter the A mouth of second two position three-way valve by the A mouth → O mouth of the 3rd two position three-way valve, flow out through the P of second two position three-way valve mouth, flow back to fuel tank by adjustable throttling, thin oil filter, the hydraulic power car to overtake at this moment.When needs slow down, adjust the opening of adjustable throttling, realize Reduced Speed Now.When the need neutral gear slides, second two position three-way valve is placed second position, this moment, power oil was entered the A mouth → O mouth of second two position three-way valve through the A of the 3rd two position three-way valve mouth → O mouth by the outlet of bidirectional variable oil motor, enter the bidirectional variable oil motor through the P of first two position three-way valve mouth → A mouth, form the neutral gear circulation loop.When at smooth road or descending, having excess energy to store, the 3rd two position three-way valve is placed the second place, the power oil that suck through the manpower pump this moment is after the P of first two position three-way valve mouth → the A mouth enters the bidirectional variable oil motor, P mouth by the 3rd two position three-way valve enters energy storage, when the energy in the release energy storage, the 3rd two position three-way valve is placed to overtake position, two position two-way valve is placed communicating position, this moment, the high voltage power oil in the energy storage was through the P of two position two-way valve mouth → A mouth, entered the bidirectional variable oil motor simultaneously after converging with the power oil of manpower pump output.When needing reversing, can be in two kinds of situation, a kind of is that the manpower pump works on, first, second two position three-way valve is placed the second place, the power oil that the manpower pump pumps flows out through the O of second two position three-way valve mouth → A mouth, flow into the bidirectional variable oil motor through the O of the 3rd two position three-way valve mouth → A mouth, flow back to fuel tank through the A of the one or three two-port valve mouth → O mouth again.Another kind of reversing method is as reverse-drive power by the kinetic energy in the energy storage, only need the first and thirdth two position three-way valve is placed the second place, namely the 3rd two position three-way valve P mouth is communicated with the A mouth, the A mouth of first two position three-way valve is communicated with the O mouth, high voltage power oil in the energy storage drives the bidirectional variable oil motor and moves backward, and power oil flows out to fuel tank from the O mouth of first two position three-way valve.Adopt a plurality of manpower pumps and check valve to constitute manpower pump group, can realize that many people drive simultaneously.Compared with prior art, have compact conformation, volume is little, and cost is low, power conversion efficient height, can realize advancing, falling back, and kinetic energy can be stored, can discharge as required, useful work can improve more than 2 times, the time scooter 30～60Km/h, consumes energy can not be widely used on cart, three-wheel vehicle or the four-wheeled.
