Problems solved by technology

[0003] In order to solve this problem, the current single-motor multi-speed hybrid transmission adopts a planetary row structure and uses the ECVT mode (the hybrid transmission with integrated motor drives the motor to generate electricity while driving the vehicle, that is, the drive-generation synchronous mode) to start, but Generally, two or more planetary rows are connected to form multiple gears, and multiple wet clutches, brakes, and hydraulic modules are required as actuators, which increases the complexity of the system

Abstract

The invention discloses a hybrid power four-gear transmission, a hybrid power driving system and a hybrid power vehicle. The technical problem that an existing hybrid power four-gear transmission is complex in structure is solved. The hybrid power four-gear transmission comprises a box body, a single planet row, a first executing mechanism, a second executing mechanism, a first parallel gear shifting gear, a second parallel gear shifting gear and an output transmission mechanism. A gear ring and a sun wheel shaft of the single planet row are used for transmitting torque of an engine and torque of a first motor respectively. Due to the fact that power flow of the engine is input through the gear ring and output through the planet carrier / sun wheel shaft, compared with the power form of planet carrier input and gear ring output in the prior art, larger torque can be obtained at the output end of the planet row, the power performance is good, only one planet row needs to be arranged, and the structure is simplified. And the first executing mechanism and the second executing mechanism are connected with the planet carrier and the sun wheel shaft correspondingly, no external gear is arranged on the gear ring, and the structure of the hybrid power four-gear transmission is further simplified.

Description

technical field [0001] The application belongs to the technical field of hybrid vehicles, and in particular relates to a hybrid four-speed transmission, a hybrid drive system and a hybrid vehicle. Background technique [0002] With the increasing shortage of oil supply and the increasing environmental pollution, the hybrid transverse transmission drive system with good fuel economy, low emission, fuel saving rate and power has attracted more and more attention. The single-motor multi-speed hybrid transmission is a common hybrid transmission, which cannot start and run in time when the battery power is low. [0003] In order to solve this problem, the current single-motor multi-speed hybrid transmission adopts a planetary row structure and uses ECVT mode (the hybrid transmission with integrated motor drives the motor to generate electricity while driving the vehicle, that is, the drive-generation synchronous mode) to start, but Generally, two or more planetary rows are conne...
