Problems solved by technology

[0003] Although the current hybrid transmissions have realized the above driving modes, and achieved the purpose of energy saving and emission reduction by switching the corresponding working modes according to different working conditions, the current systems have certain technical limitations, and AT transmissions have stepped The variable speed makes the engine unable to work in the most efficient area all the time, so that the efficiency of the engine cannot be maximized, and starting the engine during pure electric driving will cause a sudden change in the driving torque of the vehicle to produce a sense of shock, affecting driving comfort

Abstract

The invention provides a hybrid power device and a vehicle. The hybrid power device is used for the vehicle and comprises an electric driving mechanism for driving wheels of the vehicle; a power generation mechanism used for being connected with an engine of the vehicle; a stepless speed change mechanism used for adjusting the speed of the vehicle; and a clutch set; wherein when the clutch set isin a combined state, and the power generation mechanism and the engine are connected with the electric driving mechanism through the stepless speed change mechanism; when the clutch set is separated,the power generation mechanism and the engine are separated from the electric driving mechanism. Through the hybrid power device, the engine, the power generation mechanism and the electric driving mechanism can be ensured to operate efficiently at the same time in any mode, it is ensured that the whole vehicle can work most efficiently in any mode, and energy conservation and emission reduction are achieved; in addition, due to the fact that stable switching of power and continuous stepless adjustment of the rotating speed can be achieved, the stability and comfort of the whole vehicle in anymode can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to a hybrid power device and a vehicle. Background technique [0002] A hybrid power system in the prior art includes a motor, a power coupling mechanism and a transmission. The transmission uses a traditional multi-speed AT transmission, a DCT transmission, or a specially developed transmission consisting of a planetary gear mechanism or a fixed shaft gear mechanism. The power generated by the internal combustion engine or the electric motor is transmitted to the transmission respectively, and the power is output to the wheels through the transmission, and the internal combustion engine and the electric motor can output power to the transmission independently or simultaneously, or the energy of the internal combustion engine simultaneously drives the wheels and stores the energy through electric power generation. Usually, the hybrid power system has an internal combus...
