Atul Jagannath PATIL has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11885409
    Abstract: Systems and methods for an interaxle differential (IAD). In one example, the IAD comprises a locking assembly that includes a friction clutch, the friction clutch includes a clutch pack that comprises plurality of plates configured to engage and disengage to inhibit and permit speed differentiation between a first axle differential and a second axle differential. The IAD further includes a supply lubrication passage that comprises an inlet that receives a lubricant from an enclosure surrounding an input gear of an axle differential and a first outlet flowing the lubricant to a gear coupled to the clutch pack.
    Type: Grant
    Filed: April 14, 2023
    Date of Patent: January 30, 2024
    Assignee: DANA HEAVY VEHICLE SYSTEMS GROUP, LLC
    Inventors: Brian V. Knapke, Patrick F. Rose, Atul Jagannath Patil
  • Patent number: 11885408
    Abstract: Drivetrain systems and methods are provided. In one example, the drivetrain system includes an interaxle differential (IAD) configured to receive power from a prime mover, a motor configured to drive a planetary gearset, and a ball ramp actuator configured to selectively engage a plurality of plates in a clutch pack of a friction clutch in response to receiving rotational input from the planetary gearset. In an engaged configuration, the friction clutch prevents speed differentiation between a first IAD output and a second IAD output.
