Description of drawings
The example that provides below in conjunction with accompanying drawing is described in further detail the utility model.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is schematic diagram of the present utility model.
Among the figure, 1, car body, 2, bogie truck, 3, driver's cab, 4, propulsion plant, 5, operating system.
The specific embodiment
Among Fig. 1, car body can be arranged the parts such as subordinate inverter, fuel tank, braking element 1 time, is furnished with operating system 5 on the car body 1.Bogie truck 2 is positioned at car body 1 bottom, above the bogie truck 2 traction electric machine is installed, and traction electric machine is taken turns upper gear case drive wheel traveling by being fixed on.Former and later two operating consoles are arranged in the driver's cab 3, and the driver can be by the traveling of any one operating console control vehicle.Propulsion plant 4 is placed electrical storage device, traction invertor, auxiliary inverse power supply etc.Operating system 5 comprises apparatus for work, operating system operating control.
Among Fig. 2, the power system controller receives the instruction of vehicle control device, is connected to realize the mode of operations such as startup, acceleration, braking of traction electric machine with traction invertor with the electrical storage device management system.
Electrical storage device, traction electric machine and traction invertor form the active force driving system, and contact system electric supply installation, auxiliary inverse power supply form auxiliary power drive system.Main and auxiliary power drive system consists of a kind of hybrid power transmission system.The electrical storage device management system discharges and recharges electrical storage device and controls, and the power system controller is controlled whole hybrid power transmission system (including but are not limited to electrical storage device management system, traction invertor).
Apparatus for work is obtained power from auxiliary inverse power supply, and by operating system operating control control the to fulfil assignment job requirements of car.
In the situation that the contact system electric supply installation can't be powered, backup power can be set.Set up generator set on the basis of example shown in Figure 2 with the backup power of electric power conversion apparatus as the track double-power working vehicle.Generator set and electric power conversion apparatus are fixed on the car body, and power supply is to auxiliary inverse power supply, traction invertor after the electricity process electric power conversion apparatus conversion that generator set sends.Electric power conversion apparatus can possess: rectification, inversion, boost, these several functions of step-down any one or several arbitrarily, the electricity that sends of generator set also can directly charge to electrical storage device after through the electric power conversion apparatus conversion in addition.
