Abstract: 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.

Abstract: An assembly consisting of two bevel gear angular drives which are pivotably connected to each other via a pivot bearing, the bearing system including two bevel roller bearings which are tensioned relative to each other between the two sleeves. The shaft carrying the two bevel gears is also supported via bevel roller bearings in the sleeves. In this way it is possible to obtain an assembly which is suitable for implements which transmit high tensile forces to the assembly, without the bearing system and the rotary function of the two drives being adversely affected.

Abstract: The invention relates to an angular bevel gear drive (6), for driving, or for the drive of, agricultural implements. It comprises a basic housing (9) and bevel gears (13, 14) arranged therein. The shafts (10, 11) of one or several of the bevel gears (14) are associated with individual bearing units (15) into which a torque measuring device (12) is integrated, i.e. the torque may be measured both at the input and the output end. The torque measuring device (12) operates in a contact-free way and is arranged between the bearings (18, 19) of the bearing unit (15). By combining the drive with a torque measuring instrument (12) it is possible to make optimum use of the power of the tractor and the implement or individual functional areas of the implement.

Abstract: A bevel gear angle drive suitable for use in the drive line from an agricultural tractor to an agricultural implement comprises a housing 24 with input and output shafts at right angles having respective bevel gears 36 and 38 engaged with one another within the housing. The output shaft comprises a journal 40 to which is secured the outer joint part 44 of a constant velocity ratio universal joint; the journal being supported for rotation in bearings 46 at one side of the housing and the outer joint part being supported in bearings 48 at the other side of the housing. The output shaft bevel gear 38 is mounted on the journal 40 intermediate the axially separated bearings 46 and 48.
