Problems solved by technology

[0002] Hybrid vehicles currently on the market usually use two-speed coaxial transmissions (the input and output shafts are on the same straight line), and there are problems in use: insufficient power for the whole vehicle, lack of a larger torque (1000Nm) two-speed coaxial transmission, The economical speed adjustment range is limited (the second gear ratio is 1, which cannot be changed), and the installation length of the transmission is long. Due to the limited length of the rear overhang of the vehicle, the transmission is limited in matching models

Abstract

The invention provides a hybrid power transmission, which comprises an input shaft and an output shaft that are positioned in one same axis, and a middle shaft parallel to the input shaft and the output shaft, wherein an input shaft gear is arranged on the input shaft; a first gear and a second gear are mounted on the output shaft through bearings; a synchronizer is arranged between the first gear and the second gear and can be axially mounted on the output shaft in a sliding manner through a spline; a middle shaft gear, a first middle shaft gear and a second middle shaft gear are fixedly arranged on the middle shaft in sequence; the middle shaft gear is constantly meshed with the input shaft gear; the first middle shaft gear is constantly meshed with the second gear; the second middle shaft gear is constantly meshed with the first gear; and the synchronizer is matched with the first middle shaft gear and the second middle shaft gear respectively. The transmission is simple in structure; an adjusting range of a drive ratio can be extended; an economical speed range of a whole vehicle is extended; and the fuel economy of the whole vehicle is improved.

Description

technical field [0001] The invention relates to a hybrid transmission. Background technique [0002] Hybrid vehicles currently on the market usually use two-speed coaxial transmissions (the input and output shafts are on the same straight line), and there are problems in use: insufficient power for the whole vehicle, lack of a larger torque (1000Nm) two-speed coaxial transmission, The adjustment range of the economical speed is limited (the speed ratio of the second gear is 1, which cannot be changed), and the installation length of the transmission is long. Due to the limited length of the rear overhang of the vehicle, the matching models of the transmission are limited. Therefore, how to increase the economic speed of the transmission in a wider range in the hybrid powertrain, improve the fuel economy of the vehicle, improve the power of the vehicle, and meet the matching needs of more models is the development direction of the transmission in the hybrid powertrain. It is...
