The SIVRT disclosed includes a unique, ordered geartrain; it allows a large-continuous range of input:output velocity ratios (forward or reverse). This range is controlled by fluid-coupled gearsets which direct the power flow to the output shaft. The SIVRT requires no torque converter or friction clutches and has been designed for fully-loaded work machines which must operate reliably at creep speeds for extended periods with 1-3 stop-reverse-stop-forward operations every minute of the workshift. The clutchless Vformer system disclosed herein provides a robust, heavy-duty, continuously-variable mechanical transmission especially designed and scaled for applications in vehicles and working machines which operate at creep speeds with frequently stop-start-reverse activity.

A transmission (1) includes an input shaft (2), a first and a second output shaft (3, 4), and a differential (7) with a first and a second planetary gear set (5, 6). A first gear set element of the first planetary gear set (5) is connected to the input shaft (2) for conjoint rotation. A second gear set element of the first planetary gear set (5) is connected to a first gear set element of the second planetary gear set (6) conjoint rotation. A third gear set element of the first planetary gear set (5) is connected to the first output shaft (3) for conjoint rotation. A second gear set element of the second planetary gear set (6) is connected to the second output shaft (4) for conjoint rotation. A third gear set element of the second planetary gear set (6) is connected to a stationary component for conjoint rotation. The second planetary gear set (6) is axially adjacent to the first planetary gear set (5) and the planet gears (5.4) of the first planetary gear set (5) do not axially overlap the planet gears (6.4) of the second planetary gear set (6).

A drive transmission device according to one embodiment of the disclosure includes a single differential unit to which rotation of a motor is transmitted and two speed reducers each having an operation output shaft that is coupled to the differential unit and a carrier that changes a speed of the rotation of the operation output shaft and outputs the rotation. The two speed reducers are arranged such that they are opposed to each other along a second rotation axis, and the operation output shaft and the carrier in each speed reducer are aligned in the second rotation axis direction.

A gear assembly is disclosed for driving a ram arranged in a pressing channel of a square baler so as to be movable between end positions. The gear assembly comprises at least one side gear, which may be driven indirectly by a power take-off shaft of an agricultural production machine, and at least one reduction gear which is connected downstream from the at least one side gear and may be connected on the output side to a crankshaft on which the ram is mounted. The gear assembly further includes at least one flywheel that is connected between the at least one side gear and the at least one reduction gear, and at least one shiftable clutch device that is connected between the at least one flywheel and the at least one reduction gear.
