Abstract

The invention discloses a hybrid power system and a transmission assembly. The hybrid power system comprises a planet movement mechanism, a motor connected with a transmission control piece, a first clutch mechanism, a first brake mechanism and a second brake mechanism, wherein the planet movement mechanism comprises a power input piece, the transmission control piece and a power output piece; the first clutch mechanism is selectively engaged to enable the power input piece to synchronously drive the power output piece; the first brake mechanism is selectively engaged to brake the power input piece; and the second brake mechanism is selectively engaged to brake the transmission control piece. The first clutch mechanism, the first brake mechanism and the second brake mechanism are engaged in different combination modes to enable the hybrid power system to have different work modes. By adoption of the hybrid power system and the transmission assembly, the work modes and performance advantages of the hybrid power system can be achieved through few parts.

Description

technical field [0001] Embodiments of the present invention relate to the field of power drive technology, and in particular to a hybrid power system and a transmission assembly using the hybrid power system. Background technique [0002] A hybrid system for a vehicle uses different power sources when the vehicle is in different operating modes. For example, an electro-mechanical hybrid system typically has an internal combustion engine, such as a gasoline engine or a diesel engine, and at least one electric motor. By engaging different combinations of brakes and clutches, and controlling the engine and electric motor, the hybrid system has different operating modes, such as an engine-only operating mode, an electric-only operating mode, and a hybrid operating mode, thereby helping to improve fuel economy. However, the components required by the current hybrid system, such as electric motors, brakes and / or clutches, etc., are large in number, high in production costs, and d...
