Hybrid transmission transmission structure and vehicle

Abstract

The transmission structure of the hybrid transmission and the vehicle of the present invention include an engine and a motor, the transmission input shaft is connected with the engine output shaft and the outer ring gear respectively, and is also connected with the transmission housing through a one-way clutch or brake; the motor is input to the transmission through the fourth clutch The shafts are connected, the output shaft of the motor is connected with the sun gear; the output gear of the planetary row is connected with the planet carrier; the first input gear and the first and third gear driving gears are arranged on the first intermediate shaft, and the second input gear is arranged on the second intermediate shaft , the reverse gear and the second and fourth gear driving gears. The output shaft of the transmission is equipped with the first to fourth gears and the main reduction gear of the output shaft; the first and second input gears are both meshed with the planetary output gears, and pass through the first and fourth gears. The second clutch outputs power to the first and second intermediate shafts accordingly; the reverse gear meshes with the first gear driven gear, and outputs power to the second intermediate shaft through the third clutch. The transmission efficiency is high, the engine enters and exits smoothly, and the axial dimension is small.

Description

technical field [0001] The invention belongs to the field of transmissions, in particular to a transmission structure of a hybrid transmission and a vehicle. Background technique [0002] The existing single-motor hybrid power system is based on the traditional power system, and an electric motor is added on the input or output shaft of the transmission to realize the mixed output of two kinds of power. But there are following problems: [0003] When the motor is running, it cannot make full use of the advantages of the transmission's multi-gear and wide speed ratio, the transmission efficiency is low, and the engine cannot be disconnected in the pure electric driving mode; [0004] Shock and vibration will occur when the engine and motor power are switched and imported, which will affect the driving performance; [0005] The required axial space is large, the powertrain needs to be rearranged, the transformation of the traditional powertrain is large, the development cost...
