  • Patent number: 9180842
    Abstract: A multi-plate disc brake has interleaved rotatable and non-rotatable brake discs (11) within a brake housing (13) and a ball and ramp type brake actuator (12) comprising first and second relatively rotatable annular actuator discs (20, 21) with actuator balls (22) therebetween located in circumferentially ramped pockets (20a, 21a) on opposing faces of the actuator discs. A wedge-shaped actuator member (23) has an actuating means (24A, 24B) to displace the actuator member between confronting abutments (20b, 21b) on the respective actuator discs to relatively rotate the discs to cause the balls to rise up the ramped pockets and hence expand the actuator axially to move the brake discs (11) into engagement. Cooling oil is supplied into the brake housing through the wedge-shaped actuator member (23) when the brake is engaged.

  • Patent number: 9174682
    Abstract: An engine hood and a method of making a hood for a tractor or similar vehicle, the hood being of generally inverted U-shaped configuration with an upper top portion and downwardly extending side portions. The hood is hinged adjacent one end for upward pivoting between a closed position in which an associated engine is covered and an open position which provides access to the engine. The hood has an outer skin and inner reinforcing members secured to the inside of the outer skin to form two beam-like structures which extend away from the hinge towards the other end of the hood to stiffen the hood against twisting.

  • Patent number: 9157785
    Abstract: A system is provided for determining the current weight of a vehicle and any implement or trailer being towed or carried thereby. The system has an electronic control unit and means to determine the current value of vehicle operating parameters indicative of the current wheel output torque and acceleration of the vehicle. These current parameter values are forwarded to the electronic control unit so that the unit can calculate the current vehicle weight from a predetermined relationship involving wheel output torque, vehicle acceleration and other known current operating parameters of the vehicle. The other known current operating parameters of the vehicle are wheel rolling radius, angle of inclination of the vehicle, gravitational acceleration and rolling resistance of the wheels.

  • Patent number: 9131640
    Abstract: A braking system for a rotating chopper drum (14) of a forage harvester (10) driven from an engine (11) via a drive train including a disengageable clutch (21). The drive train also drives a first pump (28) connected with the drum (14) which pumps fluid around a hydraulic circuit which includes an openable restriction (40). The system is arranged to brake the chopper drum (14) by disengaging the clutch (21) and arranging the first pump (28) to pump fluid around the circuit via the openable restriction (40) as the drum (14) continues to rotate to convert the energy of the rotating drum (14) into heat.

  • Patent number: 9045040
    Abstract: A vehicle PTO driveline (10) in which a PTO input shaft (11) drives a PTO wet clutch (12) which when engaged drives a PTO output shaft (13). The driveline has an eccentric formation (34) on the input shaft (11) which oscillates a pumping piston (31) when the input shaft rotates, which piston pumps cooling/lubricating fluid from a reservoir (25c) to the wet clutch (12). The piston is connected with the eccentric formation by a ring (33) which surrounds the eccentric formation (34) and a hollow tube (32) which is attached to the ring and which carries the piston at a lower end, the piston oscillating inside a chamber (31a) when the input shaft rotates. The chamber (31a) is connected with the fluid reservoir (25c) and the oscillating piston pumps the fluid along the hollow tube (32) into the ring (33) which then delivers the fluid into internal passages (38) in the input shaft from where the fluid flows to the wet clutch.
