Abstract: A drive assembly for an operating unit (9) of an agricultural implement or an agricultural machine has a clutch (4) with an input (34). The input (34) is mechanically and drivingly connected to a drive engine (1). A summarizing gear unit (8) has a first input (20), a second input (24) and an output (26). The first input (20) is mechanically and drivingly connected to an output (35) of the clutch (4). The output (26) acts to drive the operating unit (9). A hydraulic pump (10) is mechanically and drivingly connected to the output (35) of the clutch (4). A hydraulic motor (11) is hydraulically connected to the hydraulic pump (10). The motor (11) is mechanically and drivingly connected to the second input (24) of the summarizing gear unit (8).

Abstract: A gear drive has a drive housing (1, 2) with a driveshaft (3) exiting the drive housing (1, 2) through a bore (10). The driveshaft 13 is rotatably supported in the drive housing (1, 2) around an axis of rotation X—X. A connecting shaft (7) is arranged inside the drive housing (1, 2). The connecting shaft (7) is connected in a rotationally fast way to a drive gear (35). A torque limiting coupling (4) is arranged inside the drive housing (1, 2). The input end of the torque limiting coupling (4) is connected to the driveshaft (3). The output end of the torque limiting coupling (4) is connected to the connecting shaft (7). The driveshaft (3) and the connecting shaft (7) are supported relative to one another by a radial bearing (30). The gear drive ensures that the driveshaft (3) and the connecting shaft (7) can more easily accommodate bending moments and transverse forces.

Abstract: A driving arrangement with a free-wheel coupling has a coupling sleeve (1) and a coupling hub (10) rotatably supported in the coupling sleeve (1). Both are connected, via locking pawls (24), so that, during driving of the coupling hub (10), a slaving of the coupling sleeve (1) takes place. However, a faster rotation of the coupling sleeve (1) is allowed so that the coupling sleeve (1) can overtake the coupling hub (10). Belleville springs (25, 29) achieve a breaking effect with large lagging masses. The Belleville springs (25, 29) are kept non-rotational relative to the coupling hub (10) and are supported on the end faces (8, 9) of the coupling sleeve (1). The Belleville springs (25, 29) are pre-tensioned by means of a friction face (26).

Abstract: The invention relates to an assembly having a universal joint (1) with a first joint yoke (2), a second joint yoke (3), a cross member (4) and a gear (5). The first joint yoke (2) is rotatable around a first axis of rotation (6). The second joint yoke (3) is rotatable around a second axis of rotation (7). The cross member unit (4) articulatable connects the joint yokes (2, 3) to one another. Thus, angles of their axes of rotation (6, 7) are adjustable relative to one another. The gear (5) acts as a drive. The gear (5) is connected in a rotationally fast way to the first joint yoke (2). The gear (5) is arranged co-axially relative to the axis of rotation (6) around the center of the cross member unit (4). Thus, this assembly reduces the size of the angles of articulation of universal joints of a short driveshaft.

Abstract: A switchable claw coupling has two rotatably arranged coupling parts (2, 3). One of said coupling parts (3) is axially movable. To reduce the loads on the claws (20, 21) during the coupling operation, the coupling part 3 has a cam (22). The cam (22) at its end face is able to slide on a supporting face 28 of the other coupling part (2). A recess (23), in the supporting face (28), is engaged by the cam (22) to enable engagement within only a limited range.
