Drive assembly for an operating unit of an agricultural implement or an agricultural machine

A drive assembly for vehicles with front wheels and rear wheels, especially for tractors, agricultural machinery, construction machinery or for self-driving machines, has an engine (), a first drive () to drive the rear wheels, a second drive () to drive the front wheels, an adjustable hydraulic pump () driven by the engine (), and an adjustable first hydraulic motor (). The first hydraulic motor (), with respect to drive, is connected to the first drive () to drive the rear wheels. Also, the first hydraulic motor, with respect to drive, may be connected to the second drive (), to drive the front wheels. A second hydraulic motor (), with respect to drive, can be connected to the second drive () to drive the front wheels. The first hydraulic motor () has a high coefficient of efficiency within a first driving speed range of the vehicle. The second hydraulic motor () has a high coefficient of efficiency within a second driving speed range of the vehicle. The first driving speed range is above the second driving speed range, with both driving speed ranges overlapping.

Drive assembly for four-wheel drive vehicles

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

Driving arrangement with a free-wheel coupling

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

Assembly comprising a universal joint and a gear for a drive

A device which attaches an agricultural implement (2) to a tractor (1), and in addition, establishes a driving connection between the power take-off shaft of the tractor and the drive of the implement has, for this purpose, a drive unit (8) which includes two bevel gear angle drives (9, 10) arranged one above the other. One of the drives (9, 10) is firmly connected to the drawbar of the implement with the other one connectable to the lower steering arm of the tractor by an attaching stirrup (12). The attaching system allows the tractor and implement to pivot relative to one another around a vertical axis (25), a transverse axis (26) and a longitudinal axis (27). To achieve pivotability relative to the drive unit (8) around the longitudinal axis (27), the attaching stirrup (12) is supported by a sleeve (47) on a flange housing (39) which is arranged coaxially relative to the first connecting journal (20) of the drive unit (39) thereby achieving an improvement in the transmission of towing forces.
