An output transmission device provided in a power train for driving a work machine at a variable rotation speed, and a method of operating the output transmission device

摘要

In the present invention, an input unit (E) connected to a drive machine capable of operating at a constant rotation speed and at least one output unit (A) connected to a work machine (9) capable of operating at a variable rotation speed are provided. An output transmission device (1) provided, which includes an internal gear (5), a sun gear (6), and a plurality of planetary gears (7) as elements of a reverse converter (2) and a planetary gear transmission mechanism (4). A planetary gear transmission mechanism (4) including at least one planetary gear transmission mechanism (4) including a planetary carrier (8), and an input unit (E) includes a pump wheel (P) of a reverse converter (2) and a planetary gear transmission mechanism. The turbine wheel (T) is at least indirectly connected to the first element of (4), and the turbine wheel (T) is at least indirectly connected to the second element of the planetary gear transmission mechanism (4). The third element of the planetary gear transmission mechanism (4) relates to an output transmission device (1) that is at least indirectly connected to or forms an output unit (A). In the present invention, with the inverting converter (2) emptied, the output is transmitted between the input unit (E) and the output unit (A) of the output transmission device (1) in the first rotation speed range. The switchable control clutches (20, 16) are provided, and in the first rotation speed range, the second element of the planetary gear transmission mechanism (4), particularly the turbine wheel (T) of the reverse converter (2) and the planet. It is characterized by comprising a device (25) that at least indirectly supports and / or fixes a connection portion (28) with a second element of the gear transmission mechanism (4).
