Abstract

The invention discloses a hybrid power gearbox which comprises an input shaft, an intermediate shaft connected with the input shaft, an output shaft, an output driven gear arranged on the output shaft, a differential mechanism driven gear meshed with a differential mechanism driving gear and connected with a differential mechanism assembly, a hydraulic torque converter and a front-row planetary gear mechanism which are connected with the input shaft; a central support mechanism, a first clutch connected with the front-row planetary gear mechanism and a Ravigneaux planetary gear mechanism, a second clutch connected with the Ravigneaux type planetary gear mechanism and the intermediate shaft, a third clutch connected with the front row planetary gear mechanism and a driving disc, a one-way clutch connected with the Ravigneaux type planetary gear mechanism and a transmission shell, and a driving motor connected with the front row planetary gear mechanism through the third clutch. The hybrid power gearbox is compact in structure, many in function modes, small in space and remarkable in cost advantage, the number of gears is increased, and the fuel economic performance is improved.

Description

technical field [0001] The invention belongs to the technical field of transmissions, in particular, the invention relates to a hybrid transmission. Background technique [0002] At present, with the development of society, more and more automobiles have become the main means of transportation for people, but the exhaust emissions of automobiles have also become the cause of environmental pollution. In order to improve the deteriorating automobile emission problem, the state has implemented relevant measures to force automobile manufacturers to develop in the direction of small displacement, light weight and new energy. [0003] At present, traditional gearboxes are mainly used in society. Changing to a hybrid power route on the basis of a traditional gearbox is a relatively fast way to achieve hybrid power. [0004] Existing hybrid transmissions generally only have two gears, and most have only three gears. Moreover, most of the existing hybrid transmissions adopt the str...
