Abstract

The invention relates to a two-gear rotatable hub motor four-wheel-drive trolley which is characterized by mainly comprising a rack-and-pinion steering gear, a power-assisted steering motor, a steering gear set, a reversing transmission shaft, a two-gear hub motor and a signal processor. Wide-angle reversing and transverse movement can be achieved while the normal trolley reversing angle is achieved, two forward gears, one parking gear and one neutral gear can be achieved through the hub motor used in the invention, and meanwhile, the trolley has the advantages of being compact in structure, simple in gear shifting mode, high in transmission efficiency, high in steering freedom degree and the like. A new scheme reference is provided for a reversing mode and a transmission structure of an existing electric four-wheel drive vehicle, and good use value and application prospects are achieved.

Description

technical field [0001] The invention belongs to the field of electric wheel hub motors, in particular to a two-speed rotatable wheel hub motor four-wheel drive trolley. Background technique [0002] With the global energy crisis becoming more and more severe and energy saving and emission reduction imminent, under the pressure of energy and environmental protection, new energy vehicles will undoubtedly become the new development direction of automobiles. At present, many countries have planned to ban the sale of traditional cars and will promote new energy vehicles. Electric vehicles are one of the main force of new energy vehicles. At present, except for high-end electric vehicles, general electric vehicles generally have fixed gear ratios and lack gear design. Although the fixed gear ratio can improve the transmission efficiency, it will inevitably cause waste of electric energy, affect the mileage of the electric vehicle and affect the life of the motor. [0003] The dr...
