Problems solved by technology

[0003] At present, most electric drive axle systems on the market have a single speed ratio, which can only provide a single power flow mode, and cannot take into account both speed and traction; there is only one speed ratio, and only one power flow; Obtain the required vehicle speed, but the traction force for climbing will be insufficient; setting a larger speed ratio will result in lower vehicle speed and affect effic

Abstract

The coaxial electric drive axle comprises at least one motor, at least one transmission assembly, a main shaft and two half shafts connected through a differential mechanism, each motor is in transmission connection with the corresponding transmission assembly, and when the coaxial electric drive axle is in a transmission mode, the main shaft is in transmission connection with the corresponding transmission assembly. Each transmission assembly is in transmission connection with the main shaft or a shell of the differential mechanism; the motor, the main shaft and the two half shafts have the same axis. According to the coaxial electric drive axle and the automobile, the motors transmit power to the first half shaft and the second half shaft through the transmission assembly, and the motors, the main shaft and the half shafts have the same axis, so that the coaxial electric drive axle is novel and compact in structural layout, short in power transmission chain and high in transmission efficiency; multiple power output modes are achieved, the vehicle operates efficiently, and the power requirements of diversified loads and diversified working conditions of the commercial vehicle are met.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a coaxial electric drive axle and an automobile. Background technique [0002] The motor and transmission system are important components of the electric drive axle. The main task of the motor is to input power, while the main task of the transmission system is to transmit the power from the drive motor or other equipment through gear meshing and other mechanisms to achieve deceleration and increase. The power output of torque or acceleration and torque reduction, thereby driving the movement and operation of vehicles or other transport machinery. [0003] At present, most electric drive axle systems on the market have a single speed ratio, which can only provide a single power flow mode, and cannot take into account speed and traction at the same time; there is only one speed ratio, and there can only be one power flow; The required speed is obtained, but the traction for clim...
