Problems solved by technology

[0002] In the related art, in the existing hybrid drive system, there are the following two technical solutions, one is to directly couple the motor on the traditional fuel power system to form a hybrid system, and the other is to couple the engine and The motor constitutes a hybrid power system. The former has a complex structure, many parts, takes up a lot of space, is difficult to arrange, is heavy, and has high cost. Although the structure of the latter is relatively simple, the engine has only one gear, and the engine is hybrid driven at low speed. Low, the power of the whole vehicle is relatively poor, and it is difficult for the vehicle to drive under the condition of serious power feeding from the battery

Abstract

The invention discloses a hybrid power system and a vehicle having the same. The hybrid power system includes an engine, a double input shaft transmission, a motor generator, and a differential. The double input shaft transmission is powered with the engine through a clutch. A drive gear is formed on the motor generator; the motor generator includes: a motor body, a power generation end and a drive end, and the power generation end is powered with the drive gear; the differential is respectively powered with the output shaft of the dual input shaft transmission and the drive end of the motor generator; Wherein, both the driven gear of the generating end and the driving gear of the driving end can be selectively connected to the motor body for power. As a result, the hybrid system has low space occupation, low cost, simple arrangement, and high transmission efficiency in both conventional driving and electric driving modes.

Description

technical field [0001] The present invention relates to the technical field of vehicles, and in particular, to a hybrid power system and a vehicle having the same. Background technique [0002] In the related art, in the existing hybrid drive system, there are the following two technical solutions, one is to directly couple the motor on the traditional fuel power system to form a hybrid system, and the other is to couple the engine and the motor on the single-speed reducer. The motor constitutes a hybrid power system. The former has a complex structure, many parts, takes up a lot of space, is difficult to arrange, and is heavy in weight and high in cost. Although the latter has a relatively simple structure, the engine has only one gear, and the engine is driven by a hybrid at low speed. Low, the vehicle power is relatively poor, in the case of serious battery feeding, the vehicle is difficult to drive. For hybrids, due to the intervention of the electric motor, the engine ...
