摘要： A protection arrangement for a double universal joint (1) for drives of agricultural implements has a first protection element (11), an annular second protection element (15) and a third protection element (18). The first protection element (11) has first holding projections (14) circumferentially distributed on its outer circumference (13) close to the first front edge. The first holding projections (14) project beyond the outer circumference (13) and form at least over a circumferential edge portion, distanced to the first front edge, a groove. A support tab projects beyond the first front edge. The second protection element (15) has second holding projections (17) circumferentially distributed on its outer circumference close to the second front edge. The second holding projections (17) project beyond the outer circumference and form, at least over a first circumferential edge area close to the second front edge, a second groove. An undercut portion is formed over a second circumferential edge area distanced to the second front edge. The third protection element (18) has holding portions at both ends. The holding portions include a number of first through holes (20) or second through holes, respectively. The through holes engage the holding projections (14, 17), corresponding in number to the first holding projections (14) and second holding projections (17).

摘要： The invention relates to a device for stabilizing the two lower steering arms (1) of a tractor. The lower steering arms (1) can be actuated by a hydraulic power lift (9). Each lower steering arm (1) is associated with a side strut (6) which includes a single-acting hydraulic cylinder (7) to stabilize and secure the lower steering arm (1). A pre-selection valve (12) and a control valve (13) enable the hydraulic cylinders to be connected to the power lift (9) either via a line or loaded separately by a second pressure source (P2). Thus, independently of the actuation of the power lift (9), the two lower steering arms can be centrally centered by the hydraulic cylinders (7).

摘要： A lifting device for lower steering arms of a tractor has a position recording device (25). The position recording device (25) generates a position signal representing the pivot position of the lower steering arms (2, 3). A piston-cylinder unit (11, 12) acts on the tractor and on the lower steering arm (2, 3). A switching circuit is provided per piston-cylinder unit (11, 12). The switching circuit includes a directional valve (33, 33′) with four ports and four switching positions. In a first position of the directional valve (33, 33′) all ports are blocked. In a second position, the cylinder chamber at the piston end is connected to the pressure agent supply source and the cylinder chamber at the piston rod end is connected to the return line. In a third position, the cylinder chamber at the piston rod end is connected to the pressure agent supply source and the cylinder chamber at the piston end is connected to the return line. In a fourth position, both cylinder chambers are connected to the return line. A switching unit (28, 28′) is provided with a guiding value (F). The guiding value (F) corresponds to the nominal position of the lower steering arm (2, 3). A position signal originates from the position recording device (25, 25′) and represents the respective position of the lower steering arm. A comparator compares the guiding value (F) with the position signal. The switching unit (28, 28′), as a function of the result of the comparison, causes the directional valve (33, 33′) to occupy one of the four positions.

摘要： A device for setting the length of a top link (7) of an attaching device of a tractor (1) has a piston/cylinder unit (14) for length setting purposes. The piston/cylinder (14) has a displacement sensor (20) which records the respective actual length setting of the top link (7). The displacement sensor (20) generates an actual proportional length signal. A lift position sensor (13) is provided which generates an electric signal representing the respective actual lift position of the lower steering arms (4). A nominal length setting of the top link (7), which refers to the respective actual lift position, can be stored in a storage unit (33). When a new actual lift position is reached during the automatic mode of operation, it is possible to generate an electric control signal which corresponds to the nominal length setting of the top link (7). The signal is transmitted to the comparator of a control unit (34). The comparator compares the control signal with the actual length signal. The control unit controls the piston/cylinder (14) as a function of the deviation of the signals from one another, towards a nominal length setting. In this way it is possible, automatically, to achieve optimum kinematics for an implement attached to a tractor, without any outside interference.

摘要： A coupling and centering device is attached to a journal (38) of a carrying frame (37) of an agricultural implement. The coupling and centering device has a catching ball (7) and a catching profile (14). The catching profile (14) has a sleeve (15) and a catching plate (25) which are connected to one another. The sleeve (15), in the fitted condition, enters a bore step (12) of the catching ball. The catching plate (25) is arranged relative to the sleeve (15) such that the transverse bore (19), for receiving the lynch pin, is arranged in the region of the wall of the catching plate (25). Thus, in view of a predetermined length of the journal (38) and the provision of the fixing bore (39), the greatest possible guiding length of the sleeve (15) is achieved on the journal (38). In this way, the strength of the connection is affected positively.

摘要： A coupling hook 5 for a lower steering arm 3 of a three-point attaching device of a tractor has a hook member 6 with a locking catch 7 which is spring-loaded in the direction of the locking position. The locking catch 7 is arranged in a recess 12 of the hook member 6 and extends through an aperture 13 into the bearing recess 10 to receive a bearing ball 11. For the purpose of supporting and guiding the locking catch 7, the hook member 6 is provided with a first stop face 14 and a second supporting stop 15, arranged at a distance therefrom and offset towards the rear. In the locking position, the locking catch 7 is supported on the hook member 6 by means of a first supporting face 19, a second supporting face 21 and a blocking face 22. The assembly is designed in such a way that the second supporting face 21 and the blocking face 22 form part of a recess in the locking catch 7 and that contact between the blocking face 22 and the supporting stop 15 takes place beneath an imaginary connecting line 27 between the contact point between the locking face 25 of the locking catch 7 and the outer face 26 of the bearing ball 11, on the one hand, and the center 29 of the convex supporting stop 15, on the other hand. In this way, an improved locking effect is ensured.

摘要： A coupling device for a tractor has a frame (4) which is mounted on the rear underside (3) of the tractor (1). A drawbar (14), with a coupling member (15), is guided in the frame (4). The drawbar (14) is moved by a slide (18) and can be swung sideways about a vertical axis. Centering pieces (34) and stop blocks with centering faces (35) and stop faces (38) engage one another to laterally align and fix the drawbar (14). In a lower position the drawbar facilitates lateral swivelling movement about the connecting pin (22). In an upper towing position the drawbar (14) is laterally fixed by the centering pieces (34) and the stop blocks (38). This results in improved control of the coupling members associated with the to be towed implement through lateral alignment of the drawbar and its automatic transfer into its centered position.

摘要： The invention relates to an three-point coupling device (3) for connecting a tractor to an implement (4). Two lower hitch arms (5, 5a) have been provided with catching hooks (7, 7a). An upper hitch arm (8) has also been provided with a catching hook (11). The lower hitch arms (5, 5a) may be raised or lowered by a power drive via lifting bars (10, 10a) and lifting arms (9, 9a). The upper hitch arm (8) is suspended from a holding device (20, 20a) which is associated with the lifting bars (10, 10a). As a result, the upper hitch arm (8) may be moved jointly with the lower hitch arms (5, 5a) upon actuation of the power drive which moves the lifting arms (9, 9a) and the lifting bar (10, 10a). It is no longer necessary for the tractor driver to hold the upper hitch arm (8) himself and place it on the upper coupling point (14) of the implement (4).
