Abstract: A fan assembly includes two or more axial flow fans rotatably mounted on a support structure. The fans are of the adjustable pitch type, i.e., each fan includes a pitch adjustment mechanism that is actuatable by axially shifting a positioning rod extending outward from the hub of the fan. The assembly further includes a control member and a plurality of adjustment mechanisms coupled respectively to the positioning rods and to the control member in such a way that the position of the control member determines the axial position of the positioning rods and thereby the pitch of the blades of all the fans of the assembly. A single actuator is configured to actuate a movement of the control member.

Abstract: In a combine harvester, the forward-directed driveline from the combine is coupled to the transversely oriented header drive axle through a transverse gearbox that is mounted on a moveable cradle frame onto which the header is mounted. In addition, the housing of the gearbox or at least the portion of the housing including the input axle of the gearbox is rotatably arranged relative to the cradle frame, about a rotation axis oriented transversely to the combine's forward direction. A mechanical link is furthermore provided between the rotatable gearbox housing (portion) and the feeder housing, configured to control the orientation of the input axle of the transverse gearbox, so as to maintain the alignment of the input axle relative to the driveline of the combine.

Abstract: In a combine harvester (10), the forward-directed driveline from the combine is coupled to the transversely oriented header drive axle through a transverse gearbox (26) that is mounted on a moveable cradle frame (20) onto which the header is mounted. in addition, the housing (28) of the gearbox or at least the portion of the housing including the input axle of the gearbox is rotatably arranged relative to the cradle frame (20), about a rotation axis oriented transversely to the combine's forward direction. A mechanical link (45) is furthermore provided between the rotatable gearbox housing (portion) (28) and the feeder housing (11), configured to control the orientation of the input axle (29) of the transverse gearbox, so as to maintain the alignment of the input axle (29) relative to the driveline of the combine.

Abstract: An apparatus for actuating a rocking motion of a movable component including an adjustable length actuator, a lever whose angular position is controlled by the actuator, and a force transfer element attached to the movable component. The lever comprises a pair of oppositely placed pawls shaped so as to interact with the force transfer element for respectively actuating movement of the component in one of two opposite directions, when the lever exits a neutral positional range in which range any interaction between both pawls and the force transfer element is prohibited. The neutral range may be defined by a support plate positioned, shaped, and dimensioned so as to prohibit interaction between the pawls and the force transfer element. The displacement of the component in one direction may be larger than in the opposite direction.

Abstract: An agricultural combine including a front end adapted for carrying a header via a feeder and an actuator. The combine includes a first connecting structure at an upper segment of the front end, and a second connecting structure at a lower segment of the front end. The combine further includes an intermediate frame including a feeder connector adapted for connecting to the feeder. The intermediate frame further includes a first connector connecting to the first connecting structure and a second connector connecting to the second connecting structure. The combine further includes an actuator connector adapted for connecting to the actuator. The actuator connector is provided at a location of the second connecting structure.

Abstract: An axle assembly for a vehicle includes an axle having opposite axle ends and a pair of axle hubs. The axle assembly has a pair of double kingpin hinge arrangements, each including a first pivot pin connected with a respective one of the axle ends, a second pivot pin operatively associated with a respective axle hub, and a knuckle interconnecting the first pivot pin and the second pivot pin. At least one steering cylinder is associated with each double kingpin hinge arrangement. Each steering cylinder is interconnected between the axle and the knuckle or the axle hub.

Abstract: A work vehicle equipped with a main engine, a main engine gearbox and a main engine cooling circuit for circulating an engine coolant, the cooling circuit comprising at least one sub-portion comprising a radiator for heating the driver's cabin of the work vehicle. A heat exchanger is configured for heat exchange between said engine coolant and a lubricant flowing in a circuit into and out of a gearbox other than the engine gearbox. This latter gearbox can be the traction gearbox driven by a hydrostatic motor that is in turn powered by main-engine driven pump. The traction gearbox oil is then cooled by the engine coolant when the temperature difference between the engine coolant and the traction gearbox oil is higher than when the work vehicle is in active operation in the field.

Abstract: An agricultural vehicle is disclosed having ancillary equipment that may be raised and lowered relative to the ground with consequential changing of the position of the center of gravity of the vehicle and having a hydraulic braking system comprising a master cylinder and a slave cylinder. The braking system further includes a pressure relief valve for limiting the hydraulic pressure applied to the slave cylinder only when the vehicle is in road mode. This ensures that the braking force does not exceed a safe limit below which the vehicle does not risk toppling forwards when braking.

Abstract: A final drive for an agricultural vehicle has a casing, a wheel shaft supported in the casing by means of two support bearings spaced from one another along the length of the wheel shaft, an input shaft rotatably supported in the casing with its axis parallel to but laterally offset from that of the wheel shaft, and a bull gear connected to the wheel shaft by means of a splined coupling disposed between the support bearings of the wheel shaft and having external teeth meshing with teeth on the input shaft to transmit torque to the wheel shaft from the input shaft. In order to reduce wear on the gearing of the final drive, the splined coupling between the bull gear and the wheel shaft is spherical.

Abstract: A management system is disclosed for controlling the tension of an endless track by regulating the hydraulic pressure in a hydraulic jack acting on a roller serving to tension the track. The tension management system comprises two accumulators of different capacity that are connected to the jack. Both accumulators are in permanent direct communication with the jack and the larger accumulator is preloaded to a higher pressure than the smaller accumulator.
