Embodiment 2
It refer to Fig. 3, the power source output equipment that the present embodiment provides in embodiment 1 and other alternative embodiments of the invention
On the basis of further provide a kind of dynamical system for the electric vehicle for having auxiliary equipment, including the output of described dual power source is set
Standby, the output shaft exports power source to the drive device of electric vehicle, and the operating mechanism includes the auxiliary equipment, described
Fuel feeding path output hydraulic pressure power source is to the auxiliary equipment, and in the embodiment illustrated specific to Fig. 3, electric vehicle is fork truck,
The actuating unit of the auxiliary equipment includes lift oil tank 210.The drive device refers to driving the device of forklift-walking driving.
In other alternative-embodiments, electric vehicle can also be road sweeper, and the actuating unit of auxiliary equipment then includes oily horse of sweeping the floor
Reach.
By taking fork truck as an example, most basic both of power needed for fork truck pass through double dynamical for walking and raising, the present embodiment
The concrete application of source output equipment has been saved in both unifications a to motor motor and control panel, greatly saved
Cost, also it is beneficial to maintenance and changes.
Electric vehicle is exactly power steering also in the presence of a power demand.
Therefore, in the dynamical system of the optional non-illustrated embodiment of the present invention one, in addition to steering motor and steering
Pump, the steering pump are driven by the steering motor, and the steering pump is to the steering oil by the oil in fuel tank supplied to fork truck
Cylinder.
However, the present embodiment for how simultaneously realize that power steering additionally provides another solution, in this implementation
In example, the operating mechanism also includes the steering cylinder 206 of fork truck, and the fuel feeding path is distinguished defeated by a pressure-gradient control valve 207
Go out hydraulic power supply to lift oil tank 210 and the steering cylinder 206 of fork truck.In the present embodiment, further also pass through banked direction control valves 208
Hydraulic power is assigned to lift oil tank 210 and dump ram 209, i.e. the actuating unit of auxiliary equipment can also include tilting oil
Cylinder.
Further, in order to save energy consumption, realization of the present embodiment also to steering cylinder 206 has carried out specific arrangement,
Dynamical system also includes accumulator 203 and pressure switch 202, and the accumulator 203 is respectively connecting to the steering cylinder 206
With pressure switch 202, the pressure switch 202 is connected with the magnetic valve 201；
The pressure switch 202 reaches preset range to the oil being passed through when the accumulator 203 and steering cylinder 206
When trigger the magnetic valve 201 and open so that the logical oil of the short logical oily path.
Specifically, after required oil is passed through, wherein pressure reaches to a certain degree, and at this moment pressure switch is triggered,
So as to trigger magnetic valve connection.After opening magnetic valve 201, oil circulates in short logical oily path, empty equivalent to double-direction gearpump 1 to beat
Oil.
When a pressure switch 202 is only illustrated in figure, but being actually used, its quantity is two, respectively for pressure
The preset upper limit of power is configured with pre-determined lower limit, and the quantity of the pressure switch is two；
When one of them pressure switch reaches the upper limit to the oily oil pressure being passed through when the accumulator and steering cylinder
The magnetic valve is triggered to open so that the logical oil of the short logical oily path, so as to stop to the accumulator fuel feeding；Now two-way oil
Pump carries out partial circulating not to accumulator fuel feeding.
When another pressure switch reaches lower limit to the oil being passed through when the accumulator and steering cylinder, described in triggering
Closed electromagnetic valve so that the short logical oily path blocks, so as to which double-direction gearpump is to the accumulator fuel feeding.
The steering hydraulic device of electric vehicle (fork truck is enumerated as in the present embodiment) with auxiliary equipment also includes preferential
Valve 207, an output end of the pressure-gradient control valve 207 are connected to the accumulator 203 and steering cylinder 206, the pressure-gradient control valve 207
Another output end be connected to other hydraulic means, due to the present invention electric vehicle there is auxiliary equipment, attached dress
Putting can be driven by hydraulic means, so, it is output to other hydraulic means, such as the lift cylinder of fork truck, the motor pump
The oil that end system is confessed exports through the pressure-gradient control valve.
In addition, in the present embodiment, the magnetic valve is chosen as bi-bit bi-pass normally-open normally-close magnetic valve.
In summary three embodiments, one aspect of the present invention introduce a clutch so that between output shaft and main shaft
Separation can be realized, exports power source respectively；On the other hand, invention introduces oil pump end system, in oil pump end system, due to
Short logical oily path is introduced, when clutch combines, short logical oily path progress sky need to be only turned on and buy oil so that main shaft exports power
When, the influence of the rotation of double-direction gearpump to power output substantially reduces.By taking fork truck as an example, when electric vehicle is walked, main shaft leads to
The driving power of output shaft output walking is crossed, clutch combines, and does not need raising, now turns on short logical oily path and carries out empty beat
Oil so that the resistance of output shaft output power substantially reduces, so as to influence very much the power output of hoofing part.
