Abstract
In this paper the use of a combined electro mechanical drive for driving wheels of vehicles make it possible to realize potential of a stepless transmission. In this case, the use of various differential mechanisms that summarize the movement from the internal combustion engine (ICE) and the electric motor can reduce the unevenness in time of the traction force on the drive wheels. Improving energy efficiency of hybrid vehicles is also possible by ensuring the engine operation at a constant high-speed mode. In tis paper the results of evaluating the reduction of energy losses during acceleration of the vehicle and the engine at constant speed. The use of continuously variable transmission (variator, electric and electromechanical transmission) along with other advantages allows the engine to operate at a constant angular speed. In this case, when accelerating a car, energy is saved due to the absence of its costs for accelerating the rotating masses of the engine. For cars, 4-6% of energy, and for trucks, 17%. We carried out mathematical modeling of a mechanical transmission (in more different works) and an electromechanical (combined or hybrid). The article presents the results of their comparison. Energy saving with an electric or hybrid drive of the drive wheels is achieved by reducing the amplitude of fluctuations in torque and traction of the car.
