Embodiment Construction

[0047] In order to better explain the solution of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0048] Such as figure 1 As shown, the hybrid automatic transmission of the present invention can be divided into four parts: the first power input unit 101 , the second power input unit 103 , the core transmission unit 102 and the rotational speed balance unit 104 .

[0049] The first power input unit 101 includes a first drive motor M1, an internal combustion engine E1, a clutch K0, and a two-speed gearbox composed of a third brake B3, a fourth brake B4, a fourth planetary row PG4, and a fifth planetary row PG5; the internal combustion engine E1 The output end of the first driving motor M1 is connected to the input end of the first driving motor M1 through the clutch K0, and the output end of the first driving motor M1 is connected to the input end of the two-speed gearbox.

Abstract

In order to solve the technical problem that an existing dual-output transmission automatic transmission has high requirements for synchronous control precision of two motors, the invention provides adual-output transmission automatic transmission. A special transmission line is designed, as long as three planet rows meet a specific speed ratio relation, it can be guaranteed that the rotating speed of the first output shaft and the rotating speed of the third output shaft are the same in a straight moving mode, and the requirement for the synchronous control precision of the two driving motors is avoided; moreover, an internal combustion engine or a driving motor can be switched to provide power according to different working conditions, and when the power provided by the internal combustion engine is excessive, the first driving motor can be changed into a generator to convert and store excessive energy or provide the excessive energy to the second driving motor, so that the internalcombustion engine can always work at the position of the optimal efficiency point, and the fuel economy is ensured.

Description

technical field [0001] The invention relates to a hybrid automatic transmission with double output transmission. Background technique [0002] The dual-output transmission can be applied to tracked vehicles such as tanks. Compared with the currently widely used single-flow transmission, it can realize in-situ steering, and its flexibility is greatly improved compared with the single-flow transmission. [0003] At present, most automatic transmissions with dual-output transmission control the left and right crawlers through two motors, which require high synchronous control accuracy for the two motors. Higher requirements are put forward for the electronic control system. Contents of the invention [0004] In order to solve the technical problem that the existing automatic transmission with dual output transmission requires high precision of synchronous control of two motors, the invention provides an automatic transmission with dual output transmission. [0005] Technica...
