Problems solved by technology

[0002] In the hybrid power system of the vehicle in the related art, the first motor and the second motor are coaxially arranged. In this solution, a transmission gear with a large center distance between the engine and the first motor and the second motor needs to be used, resulting in cost and volume and the increase in weight, and the motor shafts of the first motor and the second motor are arranged parallel to the output shaft of the engine, which affects the flat design to a certain extent
In addition, when it is necessary to adjust the overall output transmission ratio, there are many transmission amplitudes that need to be adjusted, that is, there are many limiting factors for adjusting the output transmission ratio.

Abstract

The invention discloses a hybrid power system and a vehicle with the same, the hybrid power system comprises an engine, the engine is provided with an engine output shaft, and the engine output shaft is connected with a driving gear through a clutch; and the driven gear is meshed with the driving gear. The first motor is provided with a first motor shaft, and the first motor shaft is in transmission connection with the driving gear through a first transmission assembly; the second motor is provided with a second motor shaft, and the second motor shaft is in transmission connection with the output shaft of the engine through a second transmission assembly; the central axis of the engine output shaft, the central axis of the first motor shaft and the central axis of the second motor shaft coincide with one another. The hybrid power system has the advantages of being small in size, light in weight, low in cost, convenient to adjust the transmission ratio and the like.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a hybrid power system and a vehicle having the same. Background technique [0002] In the hybrid power system of the vehicle in the related art, the first motor and the second motor are coaxially arranged. In this solution, a transmission gear with a large center distance between the engine and the first motor and the second motor needs to be used, resulting in cost and volume and weight increase, and the motor shafts of the first motor and the second motor are arranged parallel to the output shaft of the engine, which affects the flat design to a certain extent. In addition, when the overall output transmission ratio needs to be adjusted, there are many transmission amplitudes that need to be adjusted, that is, there are many limiting factors for adjusting the output transmission ratio. Contents of the invention [0003] The present invention aims to solve at least one of th...
