  • Publication number: 20160298603
    Abstract: A wind turbine includes a rotor shaft configured for operation by a rotor; a drive shaft configured to be driven by the rotor shaft; and a generator driven by the drive shaft. The wind turbine further includes a hydraulic cylinder arrangement acting between the rotor shaft and the drive shaft. The hydraulic cylinder arrangement is configured to allow relative rotation between the rotor shaft and the drive shaft.

  • Publication number: 20160298604
    Abstract: A wind turbine includes a rotor shaft configured for operation by a rotor; a drive shaft configured to be driven by the rotor shaft; a generator driven by the drive shaft and a torque control mechanism provided between the rotor shaft and the drive shaft. The torque control mechanism includes at least two links extending between the rotor shaft and the drive shaft. The links include a first end and a second end, the first end being pivotably connected to the rotor shaft and the second end being pivotably connected to the drive shaft. The length of each link is variable.

  • Publication number: 20070288140
    Abstract: A vehicle control system includes at least one driver input, a supervisor and at least one sub-system controlled by the supervisor. The supervisor assesses the driver input to establish actual driver demand and controls the sub-systems accordingly. As a result intuitive driver demand is identified and met.

  • Publication number: 20060105878
    Abstract: A vehicle transmission system includes an input shaft (2) connected to a differential mechanism, which has two output shafts (12, 20). The two output shafts carry first and second coaxially mounted sun wheels (10, 12), respectively, of an epicyclic gear system which mesh with first and second sets of planet wheels (P1, P2), respectively, which mesh with first and second annulus wheels (A1, A2), respectively. Each planet wheel (P1, P2) is mounted to rotate independently about a respective planet shaft (22) and the planet shafts are connected to a common carrier (24), which is rotatably mounted coaxially with the first and second sun wheels. The first and second annulus wheels (A1, A2) are connected together. The carrier (24) is connected to selectively operable speed changing means (28) arranged to increase or decrease the speed of rotation of the carrier about its axis.
