Patent number: 11428303Abstract: Methods and systems for a locking mechanism in an inter-axle differential are provided. A vehicle system, in one example, includes an electric motor coupled to a clutch assembly in a locking mechanism of an inter-axle differential coupled to a first axle and a second axle, the clutch assembly is configured to selectively disengage the locking mechanism, and in the disengaged configuration the locking mechanism permits speed differentiation between the first and second axles. The system further includes an electric motor brake coupled to the electric motor and configured to selectively apply a brake torque to the electric motor and the electric motor is configured to actuate the clutch assembly.Type: GrantFiled: June 16, 2021Date of Patent: August 30, 2022Assignee: Dana Heavy Vehicle Systems Group, LLCInventors: Brian Knapke, Patrick F. Rose, Benjamin J. Passino, Daniel D. Carmean

Patent number: 11391370Abstract: An actuation assembly for use in a drive unit assembly of a vehicle. The actuation assembly includes an actuator shaft that is connected to a shift shaft and a shift fork via a lever member. At least a portion of the lever member is connected to the shift shaft and at least a portion of the lever member is pivotably connected to said actuator shaft. An actuation mechanism drives the actuator shaft linearly to pivot the lever member which in turn rotates the shift shaft and the shift fork.Type: GrantFiled: April 12, 2019Date of Patent: July 19, 2022Assignee: Dana Heavy Vehicle Systems Group, LLCInventors: Daniel D. Carmean, Robert L. Vailliencourt, William F. Waltz

Patent number: 11125316Abstract: A drive unit assembly having a shroud for use in a vehicle. The drive unit assembly includes a ring gear having an outermost surface, an innermost surface, a first side and a second side. A plurality of ring gear teeth circumferentially extend from at least a portion of the second side of the ring gear of the drive unit assembly. The shroud of the drive unit assembly includes a first shroud member that is integrally connected to at least a portion of a second shroud member. At least a portion of the ring gear is disposed within at least a portion of the shroud of the drive unit assembly.Type: GrantFiled: March 8, 2019Date of Patent: September 21, 2021Assignee: Dana Heavy Vehicle Systems Group, LLCInventors: Daniel D. Carmean, Benjamin J. Passino, Shane T. Smith
