  • Viscous coupling and power take off assembly for a drive train system
    Patent number: 10843558
    Abstract: A drive train system includes a source of rotational energy, a viscous coupling and power take off assembly that is rotatably driven by the source of rotational energy, and a rotatably driven device that is rotatably driven by the viscous coupling and power take off assembly. The viscous coupling and power take off assembly may include a power take off that is rotatably driven by the source of rotational energy and a viscous coupling that is rotatably driven by the power take off. Alternatively, the viscous coupling and power take off assembly may include a viscous coupling that is rotatably driven by the source of rotational energy and a power take off that is rotatably driven by the viscous coupling. Lastly, the viscous coupling and power take off assembly may include a combined viscous coupling and power take off assembly that is integrated into a single housing.

  • Power take-off unit with attached pneumatic valve
    Patent number: 10286779
    Abstract: A power take-off unit includes a housing, an input mechanism mounted at least partially within the housing and configured for attachment to a source of rotational energy, and an output mechanism is configured for attachment to a driven accessory. The power take-off unit also includes a clutch assembly configured to selectively connect the output mechanism to the input mechanism. A pneumatic valve manifold is attached to the housing and is configured to provide pressurized air to the clutch assembly.

  • Power take-off having reduced gear noise
    Patent number: 9494227
    Abstract: A power take-off that significantly reduces the amount of undesirable noise that is transmitted therethrough during operation includes a housing, an input mechanism, and an output mechanism. The input mechanism is disposed within the housing and is adapted to be connected to a source of rotational energy. The output mechanism is also disposed within the housing and is adapted to be connected to a driven device. The output mechanism is adapted to be rotatably driven by the input mechanism. At least one of the input mechanism and the output mechanism includes a shaft having at least one portion that is supported on the housing by a vibration damping material.
