Patent number: 11654769Abstract: A driveline unit housing includes a body defining an interior, a central portion, and a plurality of openings each adapted to receive a shaft. A mounting body has a mounting surface defining one of the openings, the mounting surface includes a plurality of mounting holes and has a peripheral length greater than that of the central portion. Support walls extend between the central portion and mounting body, and extend axially relative to an axis of rotation of a shaft received through the opening defined by the mounting surface, and at least a majority of the support walls extend radially and a plane through and parallel to each such support wall intersects an axis of the mounting holes and the axis of rotation. Spaces defined between the support walls span a majority of a circumference of an imaginary circle that intersects each support wall.Type: GrantFiled: September 30, 2020Date of Patent: May 23, 2023Assignee: GKN Automotive LimitedInventor: John Eckart

Patent number: 9958045Abstract: A drive device for four-wheel-drive motor vehicles includes a primary axle which is driven by a drive assembly via a center differential and a secondary axle which is driven via the primary axle and via a transmission. Side differentials are arranged on the output elements of the primary axle coaxially to the center differential of the primary axle. The drive elements of the side differentials have a drive connection to the output elements of the center differential, and the output elements of the side differentials have a drive connection to the driveshafts of the primary axle and to the driveshafts of the secondary axle via multiple belt drives.Type: GrantFiled: June 3, 2014Date of Patent: May 1, 2018Assignee: Audi AGInventor: Christian Meixner

Patent number: 7080707Abstract: A drive axle assembly includes a pair of axleshafts connected to a pair of wheels, and a drive mechanism for selectively coupling a driven input shaft to one or both of the axleshafts. The drive mechanism includes first and second drive units that can be selectively engaged to control the magnitude of the drive torque transferred and the relative rotary speed between the input shaft and the axleshafts. Each drive unit includes a planetary gearset disposed between the input shaft and its corresponding axleshaft, and a pair of mode clutches that may be activated to cause the planetary gearset to establish different speed ratio drive connections between the input shaft and the axleshaft. A control system including an electronic control unit (ECU) and sensors are provided to control actuation of the clutches so as to control the side-to-side traction characteristics of the drive axle assembly.Type: GrantFiled: August 25, 2005Date of Patent: July 25, 2006Assignee: Magna Powertrain USA, Inc.Inventor: Malcolm E. Kirkwood

Patent number: 5431606Abstract: An automotive final drive assembly which utilizes a worm gear system for speed reduction between a vehicle's engine and drive wheels. The final drive assembly is capable of reducing the high speed from the engine and delivering it to the vehicle's drive wheels, all within an extremely compact space. Furthermore, the large contact area between the thread of the worm and the teeth of the worm gear provides for a high load capacity with relatively low friction, such that the final drive assembly is efficient and operates at lower temperatures. Finally, the worm gear is a ball worm gear having a spheroidal shape. As a result, the structure of the final drive assembly is simplified and suitably rigid to maintain the threads of the worm in mesh with the teeth of the worm gear.Type: GrantFiled: August 19, 1993Date of Patent: July 11, 1995Inventor: David C.
