Problems solved by technology

[0003] However, most of the electric drive axles that appear in the new market are electric transformations on traditional axles. In the electric axle structure, the output shaft of the drive motor is connected to the wheel shaft, so that the force of the wheel is directly transmitted to the wheel. group, and deform the output shaft of the drive motor connected to it, which indirectly reduces the service life of the drive motor, and the drive motor is installed in the axle body, which is not convenient for the installation and maintenance of the drive motor

Abstract

The invention relates to an electrically-driven axle device and an electrically-driven transport vehicle, wherein the electrically-driven axle device comprises an axle support, driving motors, hub reduction gears and rims; the axle support comprises a connecting main base and connecting flanges symmetrically fixed on the left side and the right side of the connecting main base; motor mounting spaces are defined by the inner side faces of the connecting flanges and the upper end of the connecting main base; mounting bolt holes are formed in the connecting flanges, the driving motors are located in the motor mounting spaces and fixedly connected to the inner side faces of the connecting flanges through bolts, and the hub reduction gears are connected to the outer side faces of the connecting flanges through bolts; an output shaft of each driving motor is connected with the corresponding wheel-side speed reducer, the wheel-side speed reducers are each provided with a rotating output flange, and each rim is connected with the rotating output flange of the corresponding wheel-side speed reducer through a bolt. The electrically-driven axle device is simple in structure and stable in operation, deformation of the output shafts of the driving motors can be effectively prevented, and the driving motors are convenient to install and maintain.

Description

technical field [0001] The invention relates to the field of vehicle drive, in particular to an electric drive axle device and an electric drive transport vehicle. Background technique [0002] At present, most of the iron-water electric drive transport vehicles used in the smelting production line adopt a hydraulic drive system, which includes hydraulic steering, hydraulic drive axles, hydraulic lifts, etc. Factors such as climbing, bumping and vibration, or overweight transportation can easily cause the internal pressure of the hydraulic system to reach the maximum value in an instant, which will cause the seal to deform instantly, but it will take a certain time for the seal to return to its normal shape after the instant pressure is released, which is likely to cause hydraulic oil. Leakage; the second is the temperature emitted by molten iron during transportation, and the long-term work of the hydraulic system makes the oil temperature of its own hydraulic system rise. ...
