Embodiment Construction
[0017] The specific implementation will be described below in conjunction with the accompanying drawings.
[0018] like figure 1 As shown, the dual-mode drive loader in this embodiment includes an electric drive travel system and an electric drive hydraulic system, the electric drive travel system includes four hub motors 1 connected to four drive wheels, and the power of the four hub motors 1 The access end is connected to the power output end of the inverter 13 . The loader includes a series hybrid power system, and the series hybrid power system includes an engine 2 , a generator 4 , an on-vehicle battery 14 , and an inverter 13 . The on-board battery can be charged and discharged. The generator 4 is driven by the engine 2 to generate electricity, and the generator 4 is connected to the vehicle battery 14 and the inverter 13 at the same time. When the engine 2 rotates, the generator 4 generates electricity, and the generated electric energy is sent to the inverter 13, an...

The invention relates to a loader. To solve the problem that the loader uses single energy, the invention provides a dual mode driving loader. The dual mode driving loader comprises an electric driving traveling system, a series connection hybrid power system and a vehicle-mounted power adapter used for being connected with a power grid; the series connection hybrid power system comprises a motor, an electric generator driven by the motor to generate electricity, a vehicle-mounted storage battery connected with the electric generator, and an inverter connected with the vehicle-mounted storage battery and the electric generator; and the inverter is connected with the electric driving traveling system, and the electric power output end of the vehicle-mounted power adapter is connected with the inverter. The dual mode driving loader has two power sources of the motor and power grid electric power, traditional fossil fuels and power grid electric sources can be used, and dependence of the loader on the fossil fuels is reduced, and fuel oil consumption and harmful emissions are reduced; and two driving modes adopt different energy supplying devices, share the same executive device (such as the electric motor), a transmission system of the loader is simplified, and the transmission efficiency is improved.
Description
technical field [0001] The present invention relates to a loader, and more particularly, to a dual mode drive loader. Background technique [0002] Traditional loaders generally use diesel engines as the only power source. Due to the frequent changes in load conditions during loader operation, in order to adapt to the power requirements of different working conditions, the engine needs to frequently shift the operating point transiently, which is very important for keeping the engine working at a low The fuel consumption area, thereby reducing the fuel consumption of the engine and reducing harmful emissions is very detrimental. [0003] The series hybrid technology can effectively stabilize the operating point of the engine, and convert the mechanical energy output by the engine into electrical energy through the generator. At the same time, the electrical energy can use the motor to output mechanical energy in a timely manner under the adjustment of the on-board power supp...
