Vehicle transmission method and vehicle transmission mechanism of hybrid power system

Abstract

The invention discloses a vehicle transmission method and a vehicle transmission mechanism of a hybrid power system. The vehicle transmission mechanism at comprises an engine, a first clutch, a motor / power generator, a power transmission gear pair, a second clutch and a motor, wherein the first clutch is arranged between the engine and the motor / power generator; the second clutch is arranged between the motor / power generator and wheels as well as between the first clutch and the wheels; the power transmission gear pair is arranged between the first clutch and the wheels as well as between the motor / power generator and the wheels; the wheels can be driven by the motor directly or through a gear. According to the vehicle transmission method and the vehicle transmission mechanism, disclosed by the invention, the advantages of the hybrid power system are remained; meanwhile, on the premise that uninterrupted connection between the hybrid power system and the wheels is ensured, parts and structures such as a transmission, a starter and a small power generator in a common hybrid power system can be removed, the structure of the hybrid power system is simplified, the weight of the hybrid power system is reduced, impact in the hybrid power system due to power exchange can be reduced, and meanwhile, the hybrid power system can be very conveniently allocated into a two-wheel-drive or all-wheel-drive system.

Description

technical field [0001] The invention relates to the technical field of vehicle hybrid power systems, in particular to a vehicle transmission method and mechanism of a hybrid power system. Background technique [0002] As we all know, the torque and output power of the internal combustion engine increase with the increase of the speed, and there is almost no external power and torque output at idle speed, and the external output power and torque are also very small at low speed. When the specific fuel consumption is too high, the specific fuel consumption will increase. When the engine speed is limited to a relatively small speed range, the fuel consumption and exhaust emissions can be optimized through existing engine-related technologies. At the same time, the advantage of a vehicle driven by an internal combustion engine having a longer cruising range than a pure electric vehicle powered only by a battery when carrying the same weight of energy is a technical obstacle that...
