25 Work vehicle multi-coupler with breakaway feature US15000599 2016-01-19 US09968021B2 2018-05-15 Robert C. Emmert; Michael A. Holland; Fernando Sandoval; Nathanael Rehn
A multi-coupler assembly for a work vehicle includes a first bank of fluid connectors, a second bank of fluid connectors configured to matingly engage the first bank of fluid connectors along a coupling axis, and a coupler mechanism coupled to the first bank of fluid connectors. The coupler mechanism is controllable to bring the second fluid connector bank into mating engagement with the first fluid connector bank. A breakaway feature is integrated into the coupler mechanism. The breakaway feature facilitates controlled disengagement of the first fluid connector bank from the second fluid connector bank along the coupling axis during a breakaway event, such as when an implement inadvertently detaches from the work vehicle. The breakaway feature may permit controlled disengagement of the first and second fluid connector banks without requiring movement of the coupler mechanism.
26 Safety Clutch for an Agricultural Vehicle or Trailed Accessory Thereof US15727294 2017-10-06 US20180098480A1 2018-04-12 Enrico Giuliani; Xavier Bonte

30 Drive Arrangement And Process For The Drive Of An Agricultural Implement US12536864 2009-08-06 US20100036569A1 2010-02-11 Sébastien Hel; Stéphane Biziorek
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.
31 Torque limiting coupling US10243902 2002-09-13 US06749049B2 2004-06-15 Klaus Kampf; Norbert Fartmann; Karl Coenen
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.
32 Drive assembly for locking one or several operating units of an agricultural implement or of a self-propelled implement US10243850 2002-09-13 US20030069102A1 2003-04-10 Karl Coenen
A drive assembly driven by a drive unit locks one or several operating units (6) of an agricultural implement (1) or of a self-propelled implement. The operating unit (6) can be locked when switching off the drive unit or upon reaction of an overload coupling (4). The drive assembly (3) has an overload coupling (4) connected to the drive unit and driven by the drive unit in one driving direction of rotation. The overload coupling (4) is also connected to the operating unit (6). The drive assembly (3) further has a brake unit (5) connected to the overload coupling (4). The brake unit (5) is intended to be arranged in the driveline between the overload coupling (4) and the operating unit (6). Actuating mechanism (10) actuates the brake unit (5) when the operating unit is running so that the operating unit is braked and locked. Thereafter, the overload coupling is disconnected.
33 Method for controlling the power take-off shaft of a tractor US09674562 2000-12-20 US06386303B1 2002-05-14 Alfred Zibuschka; Oliver Hrazdera
The invention relates to a method for controlling the drive of the power take-off (PTO) shaft of a tractor in which the PTO shaft can be connected to the drive engine by means of a PTO shaft clutch. The tractor comprises a hydraulic power lift to which a working machine driven by the PTO shaft can be coupled. In order to improve safety and operational comfort, the inventive method is comprised of the following steps: a) the PTO shaft clutch is engaged by means of a pulse-width-modulated on/off valve when the switch for turning on the PTO shaft is activated such that the clutch starts working in a controlled manner; b) if, afterwards, the switch for changing over to an automatic mode is actuated, the PTO shaft clutch is disengaged when the power lift is lifted; when the lift is not lifted, the PTO shaft clutch remains engaged: c) if the power lift is lowered again within a predetermined time interval, the PTO shaft clutch automatically reengages; however, the clutch no longer engages after this time interval has elapsed.
34 Stowable driveline connection aid for power-driven farm implements US897471 1997-07-21 US6015016A 2000-01-18 J. Dale Anderson; Don Fuqua
The connection aid takes the form of a spring-loaded stand that is attached to the tongue of an implement for cradling support of the driveline at or near the height of the power take-off shaft of the tractor when the implement is not connected to the tractor. The driveline and the power take-off shaft can be readily aligned and reconnected when the implement is to be hitched to the tractor by simply pushing down on the driveline against the spring-loading of the stand or by slightly lifting the driveline with the help of the spring-loading of the stand to the extent necessary. Once the driveline has been connected, the stand may be swung down out of the way and into a stowed position substantially recessed below the top surface of the tongue.
35 Torque limiting coupling US558407 1995-11-16 US5718634A 1998-02-17 Felix Mikeska; Klaus Kampf; Hans-Jurgen Langen
A torque limiting coupling (1) has a coupling sleeve (5), a coupling hub (2), and driving elements (12) settable between a torque transmitting position and a disconnected position. A switching ring (27) and loading balls (24) are provided which, in the torque transmitting position, load the driving elements (12) radially inwardly. If the driving elements (12) give way in their disconnected position, the balls (24) are pushed radially inwardly until the switching ring (27) is able to slide over the balls (24) and prevent them, via a bore portion, from displacing radially outwardly. This ensures that, if the coupling hub and coupling sleeve continue to rotate relative to one another, the driving elements (12) cannot re-engage the recesses and thus assume the torque transmitting position. If the switching ring (27) is displaced manually, it must be moved into a position wherein the balls (24) are again able to escape radially outwardly, thus enabling the driving elements (12) to engage the torque transmitting position. Thus, re-engagement is only possible if the switching ring (27) is moved from its disconnected position of the driving elements (12) into the torque transmitting position of the driving elements (12).
36 Process and device for measuring and indicating load conditions in drivelines of agricultural implements US485982 1990-02-27 US5030942A 1991-07-09 Hans J. Langen; Clemens Nienhaus
During monitoring of the driveline of an agricultural implement in respect of overloading and the degree of loading, from a first occurrence of slip, the slip revolutions occurring during a measuring cycle are added up. If the number of slip revolutions exceeds a permissible number of slip revolutions, a signal is generated indicating an overloading condition, a new measuring cycle beginning upon release of the signal to be able to take into account the effects resulting from a change in the behavior of the tractor driver, the nature of the signal being changed responsive to the speed differential between the input speed and output speed of a friction coupling permitting relative rotation. Furthermore, the condition of loading is indicated on the basis of the ratio of the actually measured number of slip revolutions to the number of maximum permissible slip revolutions so that the driver receives a warning prior to a blockage or case of overloading which may lead to overheating or destruction of the coupling serving to protect the implement.
37 Coupling member US197341 1980-10-15 US4387910A 1983-06-14 Cornelis van der Lely
An overload coupling member is used as a strut to interconnect the upper link of a tractor lift device with an implement, such as a cultivator. The member includes two portions that are moved towards one another upon overload to allow the implement to pivot upwardly on the other two links. One portion has an inner end sleeve pivoted to a further sleeve on the other portion's inner end and relative movement between the two portions is prevented by a shear pin that extends into an opening of the sleeves. Upon overload, the pin shears and the portions jack-knife until the lift raises the implement past the obstacle and the implement is then lowered. The inner opening end is normally closed by an abutment member, but when the portions are pivoted, the opening is exposed and a severed pin portion falls out. The shear pin can have a number of severable portions and be spring biased to slide in a holder and establish rigid connection between the two portions a number of times. In another version, the portions can be a cylinder and a piston with rod respectively. On either side of the piston fluid spaces are interconnected through a circuit having a pressure relief valve. The valve is biased by a spring that can be set to yield when the pressure exceeds a predetermined value. A by-pass conduit also allows movement of fluid from one space to the other accompanied by the movement of the piston in the cylinder. Thus, a set screw in the conduit can be used to open the conduit until the portions are set in desired relative positions and the member has the correct overall length.
38 Rotary cultivators US834091 1977-09-19 US4142587A 1979-03-06 John W. Woodward; Bruce H. Ashton
Rotary cultivator having resilient vibration damper acting between the cultivator's drive and a reaction member, to absorb vibration generated by varying torque reaction exerted on the drive during use.
39 Alarm device on a clutch US3786776D 1972-09-05 US3786776A 1974-01-22 BUTHE T; KUGLER M
The clutch is provided with a driven hub on which is mounted a sleeve having a number of leaf springs attached in such a manner that the free ends of the springs are freely moveable and the springs are positioned at an increasing radial distance from the periphery of the sleeve. The clutch housing as the driven member, is provided with a ring having a plurality of axial extensions which are engaged by the free ends of the leaf springs. Relative movement between the driven and driving members causes the free ends of the leaf springs to move rapidly over the axial extensions and produce an audible signal indicating the relative movement.
