Abstract

The invention belongs to the technical field of power transmission, relates to a composite stepless transmission device, and particularly relates to an electromechanical composite stepless transmission device for a wheeled load-carrying vehicle with a birotor motor. The electromechanical composite stepless transmission device comprises an engine, the birotor motor, a k1 planetary row, a k2 planetary row, a k3 planetary row, an output shaft, a birotor motor cable, a motor controller, a power battery pack and six control elements. An input shaft, the output shaft, the motor, a clutch, a brake and the planetary rows can be arranged coaxially to save space and improve power density. Only a two-layer sleeve shaft structure is needed, so that the electromechanical composite stepless transmission device is simple in structure and convenient in process. Power grade of the motor or the engine can be decreased by means of reasonable matching.

Description

technical field [0001] The invention belongs to the technical field of power transmission, and relates to a compound stepless transmission device, in particular to an electromechanical compound stepless transmission device for a wheeled load-carrying vehicle with a double-rotor motor. Background technique [0002] In the existing technology, the electromechanical compound stepless transmission can realize stepless speed regulation, optimize the working state of the engine, and enable the vehicle to obtain the best power performance and fuel economy performance. With the cooperation of the power battery pack, it can realize multiple operating conditions , such as electric driving conditions, compound driving conditions, braking energy recovery conditions, external power supply conditions, battery-assisted acceleration conditions, etc. Compared with cars, trucks need a wider transmission ratio range to meet low-speed high-torque climbing and highway driving conditions. Under ...
