The invention discloses a new energy vehicle wheel-side motor driving axle. The new energy vehicle wheel-side motor driving axle includes a crossbeam assembly. The left side and the right side of thecrossbeam assembly are each provided with a first-level speed reducer assembly. A motor driving circuit comprises a first NAND gate, a second NAND gate, a third NAND gate, a fourth NAND gate, a firsttriode, a second triode, a first resistor, a second resistor, a third resistor, a fourth resistor, an adjustable resistor, a first diode, a second diode and an inductor. According to the new energy vehicle wheel-side motor driving axle, in the motor driving circuit, conventional components are adopted, the temperature of voltage can be reliably adjusted, the production cost can also be reduced greatly, the market competitiveness of the new energy vehicle wheel-side motor driving axle is improved, and the new energy vehicle wheel-side motor driving axle is reasonable in design and suitable foruse and popularization.
Description
technical field [0001] The invention relates to the field of new energy vehicles, in particular to a new energy vehicle wheel motor drive axle. Background technique [0002] In the existing wheel motor drive axle of new energy vehicles, the primary reducer assembly is driven by the drive motor assembly, and the primary reducer assembly controls the secondary reducer to control the rotation of the wheels. By controlling the brake disc inside the wheel hub assembly, the wheel can be braked. However, when the motor drive bridge is working, it is necessary to continuously adjust the output capacity of the drive motor assembly. At this time, it is necessary to control the drive voltage, and the current drive voltage control circuit uses expensive integrated circuits, which greatly reduces the Increase the production cost of the automobile wheel motor drive axle, reduce the practical value of the automobile wheel motor drive axle. Contents of the invention [0003] In order to...
