Abstract

The invention discloses a two-shift hybrid power transmission. The two-shift hybrid power transmission comprises a planet row transmission mechanism, a two-shift variable-speed transmission mechanism,a power generation transmission mechanism and a power output mechanism. The two-shift variable-speed transmission mechanism transmits the power of a motor to the power output mechanism, the planet row transmission mechanism transmits the power of an engine to the power output mechanism, and the motor and the engine can drive in a separate mode or in a hybrid mode. The transmission replaces a clutch, the motor is used for starting, the starting torque is large, the starting performance is improved, and the emission value is reduced to zero. The transmission can achieve hybrid drive of the engine and the motor, the engine can work in a high efficiency area, the emission value is greatly reduced, and the needs of large driving force can be met. Through reasonable structure and parameter designs, the transmission enables the engine to be in an efficient working area, and thus the goal of energy saving and emission reduction is achieved.

Description

【Technical field】 [0001] The invention belongs to the field of automobile transmission systems, in particular to a two-speed hybrid transmission. 【Background technique】 [0002] At present, under the dual pressure of energy shortage and environmental pollution, countries have issued timetables for the ban on the sale of fuel vehicles, and the development of new energy vehicles has become the general trend. Under the trend of the country's increasingly stringent emission requirements for commercial vehicles and the increasing requirements of users, lightweight, automated, and environmentally friendly commercial vehicle transmissions have great market space and development potential. At present, domestic commercial vehicle transmissions generally use the engine as the power source, and the operation is manual. For the complex working conditions of commercial vehicles, the fuel efficiency of the engine is low and the emissions are high, which cannot meet the requirements for e...
