Electric loader is used the power drive principle of work: battery pack is supplied power to motor, and controller can be controlled rotating speed of motor and torque, to adapt to various operation operating modes and road surface; Motor is passed to power-transfer clutch with power, and motor output shaft is connected with the driving disc spacing pressing of power-transfer clutch, and the clutch plate of power-transfer clutch links to each other with the input shaft of change-speed box, and the effect one of power-transfer clutch is the impact load that can absorb transmission system, also can protect the motor nonoverload simultaneously; Change-speed box is a mechanical drive, has two gears of height, and low grade is used for loading operation, and top grade is used for loader walking, but the operation of gear changing mode armstrong's patent, also can electric control operation, change-speed box can before and after outputting power, in order to drive axle before and after driving.
Elec. vehicle has crucial meaning as the environmental protection vehicle in future.The major cause that the restriction elec. vehicle gets into commercial operation is the storage of electric energy, and the weight of battery is big under the prior art condition, and specific energy is low, is the major cause of restriction elec. vehicle development.But to stow the vehicle that operation is the master, its vehicle rear generally all will add a large amount of counterweights for loader, to electric loader, can use the weight of battery to replace counterweight, makes the weight of loader not need to increase.
For the such construction machinery and equipment of loader, generally all is in fixing workyard operation, the walking of long distance is eaily to the charging of battery, therefore adopting pure motor-driven driving device is relatively to be suitable for.
The technical scheme that the pure electric loader of the present invention uses power drive to take for the technical matters that exists in the solution known technology is:
A kind of pure electric loader is used power drive, is characterized in: running gear comprises motor, power-transfer clutch, change-speed box, transmission shaft and drive axle; Motor output shaft is connected with clutch driving case, and input shaft is connected with clutch driven disc, and change-speed box has two shelves of height; The output shaft of change-speed box connects transmission shaft, drive axle before and after transmission shaft drives respectively and connects.
The pure electric loader of the present invention can also adopt following technical scheme with power drive:
Described pure electric loader is used power drive, is characterized in: the take-off (propeller) shaft of change-speed box has former and later two flanges, and former and later two flanges are connected with the front and back transmission shaft respectively.
Described pure electric loader is used power drive, is characterized in: two shelves of change-speed box height are the autoshift structure.
Described pure electric loader is used power drive, is characterized in: housing one end of power-transfer clutch links to each other with motor casing, and the other end links to each other with mission case.
Described pure electric loader is used power drive, is characterized in: motor, power-transfer clutch, three of change-speed boxs link together, and are installed on the back vehicle frame of loader.
Described pure electric loader is used power drive, and be characterized in: motor is equipped with positive and negative rotating controller for motor, and battery and controller are placed on the rear end of loader.
Advantage and good effect that the present invention has are:
Owing to adopted brand-new technology scheme of the present invention, compared with prior art, the present invention is simple in structure with power drive for pure electric loader; Turbine transformer that need not be traditional has improved driving efficiency greatly, and the height two-speed transmission is a mechanical drive; Motor can be realized rotating; Change-speed box does not have backward gear, and is simple and reliable for structure, and the machine manufacture cost is lower than traditional loader hydromechanical drive.Be used as power with motor, replace combustion engine, the accuracy of manufacture of combustion engine is higher than motor and control system, and motor is the product of trouble free or few fault, its use and the work capacity of keeping in repair seldom, compare with combustion engine, cost of maintenance can reduce significantly.The present invention is except that battery, and its total cost is not higher than the loader of Applying Hydrodynamic Drive.Along with the decline of lithium cell price, the cost of this device is estimated on market, can compete with existing hydraulic transmission.Replace fuel oil with electric energy, can reduce use cost significantly.
The present invention has following obvious advantage:
1. industrial wheeled equipments such as electric loader are used power drive, and walking is with the driving of high-speed electric expreess locomotive, through power-transfer clutch and two-speed transmission and transmission shaft power are reached former and later two drive axles of loader.
