Problems solved by technology

[0003] The existing two-speed hybrid transmission has three driving modes: direct drive of the engine, independent drive of the drive motor, hybrid drive of the engine and the drive motor, and it is impossible to realize the hybrid (combined) drive of the drive motor and the generator
The hybrid transmission is generally driven by the drive motor to start. When the vehicle is started by the drive motor under some complex working conditions, there are problems such as insufficient starting power, poor power performance of the vehicle, or even failure to start.

Abstract

The invention discloses a hybrid transmission. The hybrid transmission is characterized in that a planetary gear transmission mechanism is connected with a power output mechanism, and the power outputmechanism is connected with a flange plate located at the other end of a transmission shell through an output shaft; a two-gear parallel shaft gear transmission mechanism is connected with the poweroutput mechanism; a generator transmission mechanism is connected with the planetary gear transmission mechanism; a locking mechanism is used for locking an engine input shaft; and after the engine input shaft is locked, a generator can sequentially output power through the generator transmission mechanism, the planetary gear transmission mechanism, the power output mechanism and the output shaft.According to the hybrid transmission, the hybrid drive of a drive motor and the generator can be realized, the double-motor drive is formed, the output torque of the two motors is coupled through a planetary differential mechanism, the maximum torque is output, and the power performance of the whole vehicle is greatly enhanced.

Description

technical field [0001] The invention belongs to the technical field of new energy transmissions, and in particular relates to a 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. [0003] The existing two-speed hybrid transmission has three driving modes: direct drive of the engine, independent drive of the drive motor, hybrid drive of the engine and the drive motor, and it is impossible to realize the hybrid (joint) drive of the drive motor and the generator. The hybrid...
