  • Self-locking cam washer
    Patent number: 10618555
    Abstract: A cam washer for a vehicle suspension system includes a point of rotation about which the washer is configured to rotate, and an outer surface profile where any point along the outer surface profile is configured to provide a friction angle less than a predetermined value to prevent the cam washer bolt from rotating under a load acting on the outer surface profile, the outer surface profile being a function of: i) a shortest distance from the point of rotation to the outer surface profile, ii) a longest distance from the point of rotation to the outer surface profile, iii) a position angle of the outer surface profile, and iv) a coefficient of friction of a material of the washer.
    Type: Grant

  • Torsional coupling for a mobile attachment device
    Patent number: 9234549
    Abstract: A drive assembly for a mobile attached device. The assembly comprises a hydraulic motor, a torsional coupling, and a mobile attachment device having a housing and plurality of teeth combined with a rotor shaft. The torsional coupling is combined with the assembly between the hydraulic motor and the mobile attachment device.

  • Torsional Coupling for a Mobile Attachment Device
    Publication number: 20150080135
    Abstract: A drive assembly for a mobile attached device that isolates torsion impulse loads created during operation. The assembly comprises a hydraulic motor, a torsional coupling, and a mobile attachment device having a housing and plurality of teeth combined with a rotor shaft. The torsional coupling is combined with the assembly between the hydraulic motor and the mobile attachment device to help minimize and isolate unwanted torsion impact loads generated by the rotor shaft during operation.
