  • Patent number: 9073522
    Abstract: A parking lock control element has an actuator coupled to a parking lock pawl, and a retaining device which works with the actuator to secure the parking lock pawl in the disengaged position. The connecting device is characterized in that the retaining device has a blocking slide connected to the actuator, and a blocking actuator having a slider gap, the width of the slider gap being modified in an actuating manner, wherein the blocking slide can move into the slider gap—when the slider gap is open—releasing the actuator. The connecting device reduces structural complexity and related costs. At the same time, the control element is comparatively robust with respect to manufacturing tolerances, acceleration forces, vibrations, and temperature stress. With minimal auxiliary energy, high holding forces can be achieved to secure the parking lock pawl. An emergency unlocking actuation can also be integrated in a simple manner.

  • Patent number: 9074635
    Abstract: A yaw drive for a wind turbine includes a motor, a gear assembly connected to the motor, and a torque limiter. The torque limiter is arranged between the motor and the gear assembly and is capable of transferring torque between the motor and the gear assembly, and capable of limiting torque transfer between the motor and the gear assembly when the torque applied to the torque limiter exceeds a threshold value. A torque transferring part of the torque limiter includes a first set of discs connected to the motor and a second set of discs connected to the gear assembly, the discs of the first set being arranged interleaved with the discs of the second set, thereby forming a stack of discs. A friction between the discs provides torque transfer between the discs. The discs rotate relative to each other when an applied torque overcomes the friction between the discs.

  • Patent number: 9074642
    Abstract: A hydraulic fluid filler for a motor vehicle transmission includes a set of holes through which respective springs of a spring pack extend. The filler is generally positioned adjacent to a single retainer ring or between two retainer rings associated with the spring pack. In some implementations, the filler floats between the two retainer rings, while, in other implementations, the filler is securely attached to one or both of the retainer rings. The filler reduces the volume of one of two cavities, chambers, or cylinders positioned on opposite sides of a piston that selectively interacts with a clutch assembly to engage or disengage the clutch assembly. Reducing the volume of one of the cavities, chambers or cylinders effectively reduces the time period the spring pack is then able to apply a restoring force to the piston.
