Hybrid power speed changer transmission structure and vehicle

Abstract

The invention discloses a hybrid power speed changer transmission structure and a vehicle. An engine and a motor are included, and an input shaft of a speed changer is connected with an output shaft of the engine and an outer gear ring and further connected with a speed changer shell through a one-way clutch or a brake. The motor is connected with the input shaft of the speed changer through a fourth clutch, and a motor output shaft is connected with a sun gear. A planet row output gear is connected with a planet carrier. A first input gear, a first-gear driving gear and a third-gear driving gear are arranged on a first intermediate shaft, a second input gear, a reverse gear, a second-gear driving gear and a fourth-gear driving gear are arranged on a second intermediate shaft, and a first-gear driven gear, a second-gear driven gear, a third-gear driven gear, a fourth-gear driven gear and an output shaft main reduction gear are arranged on an output shaft of the speed changer. The first input gear and the second input gear are both meshed with the planet row output gear and correspondingly output power to the first intermediate shaft and the second intermediate shaft through a first clutch and a second clutch. The reverse gear is meshed with the first-gear driven gear and outputs power to the second intermediate shaft through the third clutch. The transmission efficiency is high, engine intervention and exit are smooth, and the axial size 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...
