Embodiment Construction

[0031] The existing power split transmission device is shown in Figure 1a As shown, it has a driving part 1 and a driven part 4; it includes a set of continuously variable transmission B used as a governor, and a multi-speed gear train A; in the stepless speed regulation state of the device, the multi-speed gear train A The degrees of freedom are 2.

[0032] The speed governor B has two transmission parts that can be connected with the multi-degree wheel train A, called speed regulating parts, and its speed ratio can be adjusted steplessly. The multi-degree gear train A has at least two transmission parts 2 and 3 that move independently of each other in the gear train, which are called adjusted parts. The speed regulating parts are respectively connected with one regulated part.

[0033] In the multi-degree gear train A, the adjusted parts that can be connected with the speed regulating parts respectively are called the available adjusted parts; including the adjusted parts...

Abstract

An embodiment of the invention disclose a power dividing multistage stepless variable-speed transmission device and a stage changing method thereof and relates to a multistage power dividing variable-speed transmission device using a friction type and hydraulic stepless transmission to regulate speed. The device has multiple different zero-distribution speed ratios which include a dividing speed ratio. The speed regulating range of the device is divided into multiple or at least two speed ratio stages through the dividing speed ratio. Due to the fact that stage changing is performed at the dividing speed ratio, continuous regulating and changing of operating speed ratios during stage changing can be achieved, completely smooth and stepless speed regulation in a wide and continuous speed ratio range can be achieved, and high-efficiency transmission is achieved.

Description

technical field [0001] The invention belongs to a multi-stage continuously variable transmission device for transmitting rotary motion and power in a power split mode. [0002] In practical applications, some transmission devices of this type have other working modes besides continuously variable transmission, such as stepped transmission mode, no-load mode and so on. In this text, unless otherwise specified, the content only refers to the continuously variable transmission mode of the device. Background technique [0003] The existing power-split continuously variable transmission device, which is also referred to as "power-split transmission device" in this paper, has an active part for inputting mechanical power and a driven part for outputting mechanical power; it includes a set of gear trains with a degree of freedom greater than 1, Referred to as "Duodu wheel train"; and a set of continuously variable transmission called "governor"; the governor has two transmission p...
