Patent number: 11493091Abstract: A shaft assembly. The shaft assembly includes a joint assembly having a first joint member, a second joint member and one or more third joint members drivingly connecting said first and second joint members. At least a portion of a first shaft is drivingly connected to the second joint member. Circumferentially extending from at least a portion of an outer surface of a second end portion of the first shaft is a first and second increased diameter portion having a wall portion that connects the first increased diameter portion to the second increased diameter portion. Drivingly connected to the second increased diameter portion of the first shaft is a second shaft. During a crash condition, an amount of force is applied to the wall portion until it fractures and at least a portion of the first shaft and/or the joint assembly translates into a hollow portion of the second shaft.Type: GrantFiled: August 24, 2018Date of Patent: November 8, 2022Assignee: Dana Automotive Systems, Group, LLCInventors: Christopher B. Corpus, Jeffrey A. Dutkiewicz, Bao T. Luong, Thomas J. Marriott, Leah N. Matczak

Patent number: 11242897Abstract: A coupling assembly having a first member drivingly connected to a second member via one or more third members. A first shaft is drivingly connected to the first member and a second shaft is drivingly connected to the second member. The second member includes a flange portion having one or more seating portions on a first end portion of the flange. Additionally, the flange has one or more flange portion attachment apertures extending from the seating portions to a second end portion of the flange. An increased diameter portion of the second shaft has one or more increased diameter portion apertures extending from a first end portion to a second end portion. The flange portion apertures and the increased diameter portion apertures have a center-line with an angle from an axial center-line of the assembly. Additionally, the seating portions have an angle relative to a radial center-line of the assembly.Type: GrantFiled: November 1, 2017Date of Patent: February 8, 2022Assignee: Dana Automotive Systems Group, LLCInventors: Christopher B.

Patent number: 9470270Abstract: A tube yoke for a driveshaft assembly includes a tube seat. The tube seat comprises a base, a wall, and a plurality of stiffening ribs. The stiffening ribs extend between an inner surface of the base and an end surface of the wall. Each stiffening rib comprises an outer end portion which is attached to a middle portion and a pair of side portions. The tube yoke also includes a pair of lugs outwardly projecting from the tube seat. Each lug has a crosshole and the crossholes are aligned so as to have a common centerline. Each stiffening rib is oriented at an acute angle with respect to the common centerline of the crossholes and each stiffening rib gradually decreases in thickness from the side portions to the outer end portion and from the middle portion to the outer end portion.Type: GrantFiled: December 9, 2014Date of Patent: October 18, 2016Assignee: Dana Automotive Systems Group, LLCInventors: Philip A.
