  • Patent number: 9772011
    Abstract: A drive converter device is provided for converting a rotational drive of a drive device into a translational actuation movement for a shifting element of a transmission unit with a cam disk that is rotatable and adjustable in an axial direction is described. The cam disk is formed with track areas with defined gradients, in the area of which the cam disk is in operative connection with at least one fixed-housing element. The cam disk is translationally adjustable in respect of the elements through rotational movement of the cam disk, depending on the gradients of the track areas. Furthermore, an axle transmission device with a shifting element is described; in the area of which, an operative connection between a shaft of a differential and a shaft connectable with a wheel of a vehicle axle is able to be produced. The shifting element is able to be actuated by the drive converter device.

  • Patent number: 8764597
    Abstract: A coupling comprises a pair of clutch end members, a clutch centre member disposed between the clutch end members, and an actuator coupled to one of the end members. Each end member includes concentric V-grooves disposed on a respective face thereof. The centre member is axially movable between the end members, and includes a pair of opposing surfaces. One of the opposing surfaces includes concentric V-grooves configured to mesh with the V-grooves of one of the end members. Another of the opposing surfaces includes concentric V-grooves configured to mesh with the V-grooves of another of the end members. The actuator is configured to couple the end members and the centre member together by urging the V-grooves of the end members into engagement with the V-grooves of the centre member.

  • Patent number: 8641570
    Abstract: Infinitely variable motion control (IVMC) provides motion control without any requirement for changing gears or use of a clutch. A spur gear transgear, defined as a system having an input, an output and a control, a variable pitch cam having an eccentric inner and outer cam assembly, a driver and a one-way clutch or ratchet bearing assembly may be used to form a cam controlled speed converter converting a given input to a variable or constant output speeds and further having direction control. All IVMC's, cam controlled IVMC, input compensated IVMC and pitch controlled IVMC may be utilized to form various embodiments of infinitely variable generators, transmissions and compressors/pumps.

  • Patent number: 6641499
    Abstract: A transmission has a gear system (34) which may be in the form of an orbit system (32, 35) or a planetary orbital spur system. The gear systems include a control gear (32) which is controlled to determine the drive ratio of the transmission. The control gear is controlled by a momentum control which includes a disc (23) and a slide (25) which carries a magnet (30) for selectivity allowing or preventing rotation of the disc (23) to in turn change the speed of rotation of the control gear (32). Alternatively, the momentum control can be formed from moveable masses which move radially outwardly relative to the control shad to change the speed of rotation of the control gear.
