Simplified system for disconnecting a power outlet of a cardan in a vehicle with a trailer
Disclosed herein is a vehicle (1)—preferably a tractor—with a trailer (2) operatively connected thereto with a cardan (3), said cardan (3) comprising a power take-off, said power take-off being switched off when said cardan (3) builds with said vehicle (1) and/or with said trailer (2) an angle (ε) smaller than a first threshold value (a) and/or larger than a second threshold value (β) and being switched on when said angle (ε) exceeds again said first threshold value (β) thanks to suitable actuators, including detection means of the angle formed between the cardan (3) and said vehicle and/or trailer. According to the present invention, said angle (ε) is detected by a detector consisting of a magnetic device (4) placed on the trailer (2) or the vehicle (1) and an electronic compass (5) placed on the vehicle (1) or on the trailer (2). Preferably, the angle (ε) insisting on the cardan (3) is obtained according to the formula: ε=180−Y−arcsen (l/m sen y) (3) where y is the angle the compass (5) forms with respect to the straight travel with the magnet (4), I is the distance between the cardan (3) and the compass (5), m is the distance between the cardan (3) and the magnet (4).
Coupling
An industrial work vehicle including a frame and a first shaft rotatably connected to the frame via first and second bearings. The work vehicle further includes a second shaft rotatably positioned in line with the first shaft and connected to the first shaft via a coupling. The second shaft is further connected to the frame via a third bearing. The coupling includes a first connection and a second connection. The first connection connects the first shaft to the second shaft via a fourth bearing adapted to support a radial load and to accommodate an axial rotation and an angular misalignment of one shaft with respect to the other shaft. The second connection connects the first shaft to the second shaft via flange elements which are interconnected via an intermediary element adapted to transmit a torque and to accommodate a misalignment of one shaft with respect to the other shaft.
AGRICULTURAL BALING MACHINES
A mobile baling machine including a rotary input shaft connected by way of a driveline to a rotatable flywheel; and a drive converter that converts rotation of the flywheel to reciprocal rectilinear motion of a plunger, in a bale-forming chamber forming part of the baling machine, in manner forming plant matter in the bale-forming chamber into a compressed form; the driveline including one or more clutches for controlledly transferring rotary drive between the input shaft and the flywheel, wherein the driveline includes a transmission including driveline components defining at least first and second selectable transmission ratios between the input shaft and the flywheel; and wherein the baling machine includes or is operatively connected to one or more controllers that selectively engage a relatively lower, first said transmission ratio or a relatively higher, second said transmission ratio in dependence on conditions prevailing in the baling machine.
Vehicle with Trailer Operatively Connected Thereto With a Cardan
Disclosed herein is vehicle (1) with trailer (2) operatively connected thereto with a cardan (3), said cardan (3) comprising a power take-off, said power take-off being switched off when said cardan (3) forms with said vehicle (1) and/or with said trailer (2) an angle (α; β) smaller than a first threshold value and/or larger than a second threshold value and being switched on when said angle exceeds again said first threshold value or goes below said other threshold value, due to suitable actuators. According to the invention, it provides angle (δ) detection means between the steering wheels (5) and the axle (A) of the vehicle and means apt to correlate said angle (δ) between the steering wheels (5) and the axle (A) of the vehicle (1) with the angle (α; β) comprised between the cardan (3) and said vehicle (1) and/or said trailer (2).
SIMPLIFIED SYSTEM FOR DISCONNECTING A POWER OUTLET OF A CARDAN IN A VEHICLE WITH TRAILER
Disclosed herein is a vehicle (1)—preferably a tractor—with a trailer (2) operatively connected thereto with a cardan (3), said cardan (3) comprising a power take-off, said power take-off being switched off when said cardan (3) builds with said vehicle (1) and/or with said trailer (2) an angle (ϵ) smaller than a first threshold value (a) and/or larger than a second threshold value (β) and being switched on when said angle (ϵ) exceeds again said first threshold value (β) thanks to suitable actuators, including detection means of the angle formed between the cardan (3) and said vehicle and/or trailer. According to the present invention, said angle (ϵ) is detected by a detector consisting of a magnetic device (4) placed on the trailer (2) or the vehicle (1) and an electronic compass (5) placed on the vehicle (1) or on the trailer (2). Preferably, the angle (ϵ) insisting on the cardan (3) is obtained according to the formula: ϵ=180−Y−arcsen (l/m sen y) (3) where y is the angle the compass (5) forms with respect to the straight travel with the magnet (4), I is the distance between the cardan (3) and the compass (5), m is the distance between the cardan (3) and the magnet (4).
Agricultural baler and method of protecting such baler from overload damage
An agricultural baler including a flywheel and a drivetrain for coupling the flywheel to a connector that is arranged to be connected to a power take-off (PTO) of a tractor. The drivetrain includes a decoupling mechanism for decoupling the flywheel from the connector in case of an overload. The decoupling mechanism includes a controllable member that is movable between an engaged state in which the flywheel is coupled to the connector and a disengaged state in which the flywheel is decoupled from the connector. The decoupling mechanism further includes a detector configured for detecting the overload. The detector is configured for providing an overload signal to the controllable member triggering the controllable member into the disengaged state.

Safety clutch for an agricultural vehicle or trailed accessory thereof
A clutch for an agricultural implement including a rotating unit for connection to a powered shaft, a selectively disengageable unit, a zero-backlash torque limiter operable in an engaged position where a biased plunger is housed in a seat to angularly connect the rotating unit and the selectively disengageable unit for torque transfer until a maximum torque level is reached; and in a disengaged position where the plunger is retracted outside the seat. Further, a safety occlusion mechanism having an obstructing element selectively movable in an obstructing position to hinder the seat from housing the plunger and in a release position to allow shape coupling when the plunger and the seat overlap. The occlusion mechanism is biased to switch in the obstructing position and the release position is instated by an operator.
