    摘要： A hybrid drivetrain for a hybrid-driven vehicle, having a transmission, which can be shifted by shifting elements into different transmission steps, and which is connectable via an internal combustion engine shaft to an internal combustion engine, via an electric machine shaft to an electric machine, and via an output shaft to at least one vehicle axis. The internal combustion engine shaft and a pinion shaft, which can be connected with respect to drive to the output shaft, are connectable via spur gearwheel sets, which can be shifted by means of shifting elements and which each form wheel levels, of which at least one hybrid wheel level is additionally connectable to the electric machine shaft.

    摘要： A dual-mode active rear-wheel steering device, including: a steering motor, a main shaft, an intermediate gear, a transmission gear, a planetary gear coupling mechanism and a mode switching assembly. An output end of the steering motor is provided with a first input gear. An end of the main shaft drives a first rear wheel to rotate by a two-stage gear transmission system and a first rear-wheel motion conversion mechanism, and the other end of the main shaft drives a second rear wheel to rotate by the planetary gear coupling mechanism and a second rear-wheel motion conversion mechanism. The intermediate gear, the transmission gear and a sun gear of the planetary gear coupling mechanism are provided on the main shaft. The intermediate gear meshes with the first input gear.
