| A drive arrangement for the drive of an agricultural implement is provided that includes a drive engine that can be brought into a drive connection over a separable power take-off shaft clutch with a power take-off shaft output. A drive line of the operating implement is connected with the power take-off shaft output, with an overload clutch, and a control arrangement. The control arrangement is connected to a sensor arranged for the detection of the torque at the power take-off shaft output and, in normal operation, permits an actuator to disengage the power take-off shaft clutch as soon as the torque detected by the sensor reaches or exceeds a first threshold value, that corresponds to a torque that is smaller than the cut-off torque of the overload clutch. Immediately following, the control arrangement orders the actuator to engage the power take-off shaft clutch and when the power take-off shaft clutch is disengaged permits a torque at the power take-off shaft output that is greater than the cut-off torque of the overload clutch. | ||||||

| A coupling has a coupling hub (1), a coupling sleeve (2), and driving dogs (60). The driving dogs 6 are adjustably guided in the coupling hub (1) transversely to a longitudinal axis (42) between a torque transmitting position and a disconnected position. Recesses (9) in a bearing bore (4) of the coupling sleeve (2) are engaged by the driving dogs (6) in their torque transmitting position for transmitting torque between the coupling sleeve (2) and the coupling hub (1). A first switching ring (43) is axially loaded by a first spring in a first direction. A second switching ring (44) is axially loaded by a second spring. A setting mechanism (23) pretensions the first spring (20). The switching rings (43, 44) allow the driving dogs (6) to be set to the disconnected position if a predetermined limit torque is exceeded. | ||||||

| A torque limiting coupling defines a longitudinal axis (17) and has a coupling hub (8) with circumferentially distributed through holes. Transfer elements are adjustably held in the holes. A coupling sleeve (6) has first recesses corresponding to the through holes. A switching disk (9) is arranged relative to the coupling hub (8) between a torque transmitting position and a freewheeling position. The switching disk (9) is urged towards the torque transmitting position. This urges the transfer elements in the direction towards the coupling hub (8). The transfer elements engage, for torque transmission, in recesses of the coupling sleeve (6). Coupling sleeve (6), when a predetermined nominal torque is exceeded, is transferable from the torque transmitting position to the freewheeling position. Second recesses, corresponding to the through holes, receive the transfer elements in the freewheeling position. A locking pawl (14), in a retaining position, interacts at least with one switching face (11) of the switching disk (9). The switching disk (9) is transferable from the torque transmitting position into the freewheeling position. In the retaining position, the locking pawl interacts with a first retaining face (19) of the coupling hub (8) so that the torque limiting coupling (1) is retained against rotation. | ||||||

| The invention relates to an agricultural machine (1) couplable to a tractor (3) and drivable from the tractor (3) and having at least one consumer (10, 12) supplied with electrical energy. In order to ensure operational reliability of the electrical consumers (10, 12) of the agricultural machine (1) despite increasing demands, it is proposed according to the invention that, for power supply, the agricultural machine (1) comprises its own on-board electrical system (17) having at least one energy generator (13) and/or energy storage mechanism (15) of its own. | ||||||

| A torque limiting coupling for a driveline for driving agricultural implements has a coupling hub (7) with first recesses (14) which receive adjustable driving members (17). The coupling hub (7) further includes second recesses (15) which include a spring assembly (30). Switching cams (27) of the spring assembly (30) load the associated driving member (17). A coupling sleeve (32) is arranged around the coupling hub (7). Covers (37, 38) laterally seal the unit and laterally guide the coupling hub (7). Sealing rings (47, 48) are provided to render the unit oil-proof. Oil at least partially fills the free space between the components. Thus, the unit ensures in the case overloading occurs, the driving members (17), which engage a groove (34) in the torque transmitting position, cannot return into the groove (34) until a relatively low rotational speed has occurred. At high relative rotational speeds, the oil contained in the grooves (34) during rotation prevents the driving members from re-entering the grooves (34). | ||||||

| A curved implement tongue improves the turning characteristics of the implement, such as a mower-conditioner. The tongue is bent in the horizontal plane and incorporates a generally vertical box section at the end of the tongue. The tongue supports a driveline transmitting rotational power from a prime mover to the operative components of the mower-conditioner. | ||||||

| A shear bolt coupling incorporated in a drive transmission of an agricultural baler comprises a first rotatable member, a second rotatable member disposed coaxial with the first rotatable member, and a shear bolt operatively interconnecting the first and second rotatable members for transmitting power therebetween during normal operation. The shear bolt is arranged to shear off under excessive load conditions in order to interrupt power transmission between the rotatable members and thereby permit the rotatable members to move relative to each other. A shear bolt introducing lever is operatively associated with either the first or the second rotatable member for urging the shear bolt into a drive coupling position wherein the rotatable members are drivingly coupled together. The shear bolt introducing lever is movable relative to the rotatable members between an inoperative position clear of a shear bolt introducing area of the rotatable member having the shear bolt introducing lever associated therewith for enabling insertion of a new shear bolt, and an operative position for urging the new shear bolt into the drive coupling position. | ||||||
| 57 | Power takeoff shaft for a farm tractor | US35735 | 1987-04-08 | US4776226A | 1988-10-11 | Walter Zenker |
| A power takeoff mechanism for a farm tractor with two interchangeable power takeoff shafts which can be driven at different speeds and are connected by means of annular flanges of different diameters with a driving flange on the end of an output shaft wherein a pawl is pivoted near the driving flange and is connected to a clutch lever of the gear shifting mechanism whereby the pawl must be pivoted to a predetermined position when one of the power takeoff shafts is installed, thereby preventing the clutch lever from being operated in a manner to select an inappropriate speed for the installed power takeoff shaft. | ||||||
| 58 | Overload clutch | US524302 | 1983-08-18 | US4566570A | 1986-01-28 | Hubert Geisthoff |
| An overload clutch wherein a clutch hub and a clutch sleeve are brought into and out of driving engagement by spring loaded driving members in the hub engaging into recesses in the sleeve. The disengagement of the clutch is achieved in stages by constructing the recesses so that the driving members will disengage individually at different torque transmission levels. More specifically, the depth of the recesses is varied to vary the disengagement levels of the driving members. | ||||||
| 59 | Shear pin coupling | US4165 | 1979-01-17 | US4292819A | 1981-10-06 | Ary van der Lely; Cornelis J. G. Bom |
| A shear pin coupling comprises two coupling parts which are normally interconnected by a shear pin. Upon overload, the shear pin fractures and the parts can rotated relative to one another. After fracture, the shear pin is advanced to re-interconnect the coupling parts by a spring-loaded plunger. The shear pin and the plunger are shaped to prevent displacement of the shear pin in a direction other than its lengthwise direction. The end of the pin may, for example, be conical for this purpose. | ||||||
