Problems solved by technology
This structure has higher transmission efficiency, but it is suitable for matching larger tires
[0005] For the current domestic 90-120 ton mining vehicle electric transmission scheme, if the electric motor is mounted on the drive axle, the reliability is insufficient, and the suspension system of the vehicle is also difficult to arrange; if the foreign large-scale electric transmission scheme is adopted, due to the tire size Not enough, the motor and reducer cannot be arranged

The invention relates to the technical field of vehicles, in particular to an electric drive axle and a vehicle. The electrically-driven axle comprises an axle housing, two motors, two first-stage speed reducers, two parking brakes, two half shafts and two hub speed reducers. The two motors are both arranged in the central axle housing. The first-stage speed reducer comprises a first shell and a first planet row assembly arranged in the first shell, and the input end of the first planet row assembly is connected with the motor shaft; the two parking brakes are arranged in the two first shells correspondingly and can brake the output end of the first planet row assembly. One end of the half shaft is connected with the output end of the first planet row assembly; the input end of the hub reduction gear is in transmission connection with the other end of the half shaft, and the output end of the hub reduction gear is connected with the hub. The device is high in reliability and can be suitable for existing tire sizes, and a scheme capable of installing the service brake and the parking brake at the same time is provided.
Description
technical field [0001] The present invention relates to the technical field of vehicles, in particular to an electric drive axle and a vehicle. Background technique [0002] At present, there are many ways to arrange the motors of the new energy-powered mining vehicle drive axles. The most conventional structure is that the drive motor drives the gearbox, and the gearbox is connected to the drive axle through the transmission shaft, thereby driving the vehicle. This solution is to simply replace the traditional internal combustion engine with an electric motor, and essentially no major changes are made to the gearbox and drive axle. In this structure, in theory, the gearbox is a redundant structure, and the entire vehicle's drive train has low efficiency and high cost. And because the gearbox has multiple gears, whether it is a mechanical structure gearbox or an automatic gearbox, there will always be a problem of shifting smoothness. [0003] There is also a driving meth...
