Embodiment Construction
[0027] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, but not to limit the present disclosure.
[0028] In the present disclosure, unless otherwise stated, directional words such as "front" and "rear" are used relative to the driving direction of the vehicle, and "inner" and "outer" refer to the contours of the corresponding components The terms "first", "second", etc. are used in the present disclosure to distinguish one element from another, and have no order or importance. Additionally, where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated.
[0029] refer to Figure 1 to Figure 4 , the present disclosure provides a hybrid transmission including an input...

The invention relates to a hybrid power transmission, a hybrid power transmission system and a vehicle, the hybrid power transmission comprises an input shaft, an output shaft, a first disconnecting device and a second disconnecting device, the input shaft comprises a core shaft connected to an engine and a sleeve shaft arranged on the outer side of the core shaft in a sleeving mode at intervals, and the core shaft and the sleeve shaft are connected in an on-off mode through the first disconnecting device; the output shaft is used for being connected with an axle; the first gear set is arranged between the sleeve shaft and the output shaft; and the first motor is selectively connected with the core shaft or the sleeve shaft. When the first motor is connected with the sleeve shaft, the connection with the engine can be disconnected, and pure electric driving is realized; when the first motor is connected with the mandrel, the first motor is connected with the engine, engine driving can be assisted, the rotating speed of the engine can be adjusted, the target rotating speed of the engine can be rapidly achieved, gear shifting is rapid, meanwhile, the engine can charge the first motor, the first motor can adjust the output torque of the engine, and torque shunting is achieved. When the engine charges the first motor, the first disconnecting device is disconnected, and the influence of loads on the sleeve shaft is reduced.
Description
technical field [0001] The present disclosure relates to the technical field of vehicle powertrains, and in particular, to a hybrid transmission, a hybrid transmission system, and a vehicle. Background technique [0002] Current hybrid drive systems can be divided into two categories, one is an add-on hybrid system, which is based on the existing conventional engine powertrain, and the electric motor is installed in a suitable location in the power transmission path; the other is a dedicated hybrid system. The transmission integrates one or more electric motors into the transmission to form an automatic transmission system with electric motors, which cooperates with the existing engine power input to realize the function of hybrid driving. At present, for the hybrid transmission with series-parallel as the main driving mode, there are problems such as a lot of load, difficulty in flexibly adjusting the operating point of the engine, and low transmission efficiency.
