Abstract

The invention discloses a novel hybrid transmission, which comprises a casing, a power source, a single planetary gear mechanism, a differential, a speed change transmission mechanism, a braking device and a first synchronizer. The single planetary gear mechanism is configured to have a differential speed or a speed change function, and can transmit the engine power and / or the power of the first electric motor to the speed change transmission mechanism after the differential speed or speed change. The speed change transmission mechanism is configured to have a speed change function, and can transmit the power of the single planetary gear mechanism to the differential at a predetermined speed ratio. A braking device configured to transmit power in at least one direction. The invention has the advantages of low manufacturing cost, small occupied space and high reliability, and can fully meet the power requirements of the hybrid vehicle in different driving conditions, and can flexibly adjust the working point of the engine to ensure its working efficiency The higher working range effectively ensures the higher efficiency of the entire hybrid system.

Description

technical field [0001] The invention relates to the field of transmission manufacturing, in particular to a novel hybrid transmission. Background technique [0002] Due to the aggravation of the world's environmental and energy problems caused by traditional fuel engine vehicles, and the adjustment of new energy vehicle policies in various countries around the world, major automobile companies are actively developing energy-saving and environmentally friendly vehicles. The hybrid power system has become a feasible technical solution to solve automobile energy consumption and environmental pollution at this stage, and its core power transmission device has become the focus of research and development by various companies. At present, most of the hybrid schemes use multiple single-planetary rows in series or in parallel, but the fuel-saving efficiency is limited. Therefore, research and development of a transmission device with higher fuel-saving efficiency and more suitable ...
