Abstract

The invention discloses a variable speed structure of a hybrid electric vehicle. A clutch is arranged between the output end of an engine and the input end of an input shaft, so that the engine is selectively combined with and separated from the input shaft through the clutch; and a motor middle shaft is parallel to the input shaft, the motor middle shaft is fixedly connected with a motor middle shaft deceleration low-gear gear and a motor middle shaft deceleration high-gear gear in sequence, wherein, the motor middle shaft deceleration low-gear gear is engaged with the motor middle shaft deceleration high-gear gear, the motor middle shaft deceleration high-gear gear is simultaneously engaged with a reverse gear shaft motor deceleration high-gear gear and a motor middle gear, and the motormiddle gear is fixedly connected to an output shaft of a motor. According to the variable speed structure of the hybrid electric vehicle, on the basis of an existing six-speed manual transmission, the 48V motor is integrated through gear transmission, the motor can serve as a driving motor, can also serve as an electric generator, and providing 48V driving power by the motor and energy recovery are achieved accordingly.

Description

technical field [0001] The invention belongs to the field of hybrid power transmission, and in particular relates to a transmission structure of a hybrid power vehicle. Background technique [0002] Existing vehicles often use gasoline as power to drive the engine to work, and the power output from the engine realizes speed change during the transmission process, and finally drives the vehicle to run. With the progress of society and the development of technology, oil-powered vehicles have high fuel consumption, cannot meet the requirements of energy saving and emission reduction, and have a single working mode, which cannot well meet the needs of users. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a transmission structure of a hybrid electric vehicle with low fuel consumption and diversified working modes. [0004] The technical solution of the present invention is as follows: a transmission structure for a ...
