Patent number: 7866423Abstract: An automotive vehicle drive unit assembly which is located near the sides of a vehicle includes a first driving axle shaft, a second driving axle shaft, a first gear box, a second gear box, a first electric motor, and a second electric motor. The first driving axle shaft drives a first wheel hub of the vehicle and the second driving axle shaft drives a second wheel hub. Together the first and second driving axle shafts define an axis of rotation about which the first and second wheel hubs rotate. The first gear set drives the first wheel and the second gear set drives the second wheel. A first electric motor is mounted in an angular relationship relative to the axis of rotation and drives the first gear set. A second electric motor is mounted in an angular relationship relative to the axis of rotation and drives the second gear set. A plurality of electric motors can be used to drive each wheel hub.Type: GrantFiled: August 24, 2005Date of Patent: January 11, 2011Assignee: Meritor Heavy Vehicle Systems, LLCInventors: Malcolm F.

Patent number: 6431298Abstract: A vehicle drive unit assembly includes a rear drive axle extending between a pair of vehicle wheels. An input shaft is operably connected to the drive axle to provide torque to the drive axle to drive the vehicle wheels. An electric motor is connected to the input shaft and is mounted above the drive axle. Preferably, the electric motor is mounted adjacent to the differential in the drive axle. A reduction gear box or chain drive assembly interconnects the electric motor to the input on the drive axle to reduce the input speed to the axle from the motor.Type: GrantFiled: April 13, 1999Date of Patent: August 13, 2002Assignee: Meritor Heavy Vehicle Systems, LLCInventors: Malcolm F. Ruppert, Jr., Silvio Masaaki Yamada

Patent number: 5924504Abstract: An automotive vehicle suspension unit assembly located near the sides of a vehicle includes a driving axle shaft, a gear box, an electric motor, and a suspension beam. The driving axle shaft, which drives a wheel hub of the vehicle, defines an axis of rotation about which the wheel hub rotates. The gear box includes a pinion shaft connected to a pinion gear which meshes with a ring gear. The pinion shaft is driven by a motor drive shaft which extends outwardly from the electric motor. The motor generates the torque necessary to drive the driving axle shaft. As known, suspension beams extend transversely to the axis of rotation of the driving axle shaft. The electric motor is pivotally attached to the gear box by means of a flexible coupling and is pivotally attached to the suspension beam by means of a movable connection.Type: GrantFiled: February 18, 1997Date of Patent: July 20, 1999Assignee: Meritor Heavy Vehicle Systems, LLCInventors: Malcolm F. Ruppert, Jr., Bradley A. Arnold

Patent number: 5878830Abstract: An improved mount for an electric motor and drive gear includes mounting both of the motor and drive gear within a gear housing for a vehicle wheel. The motor is mounted on one side of the drive axis of the wheel, and the drive gear is mounted in bearings on an opposed side of the drive axis. In this way, the overall longitudinal distance required for mounting both the motor and the drive gear is reduced when compared to the envelope of the vehicle wheel.Type: GrantFiled: February 18, 1997Date of Patent: March 9, 1999Assignee: Meritor Heavy Vehicle Systems, LLC.Inventors: Malcolm F. Ruppert, Dean Mark House, William Carl Sullivan, Silvio Masaaki Yamada

Patent number: 5791205Abstract: An improved differential case is provided that resists rotation between the two differential case halves. Spline teeth extend from each of the mating faces of the two differential case halves into grooves in the other. The spline teeth and grooves prevent relative rotation. A method of making the differential case halves is also disclosed.Type: GrantFiled: August 9, 1996Date of Patent: August 11, 1998Assignee: Meritor Heavy Vehicle Systems, LLCInventor: Malcolm F. Ruppert, Jr.

Patent number: 5697677Abstract: A modular axle assembly incorporates a separate bearing support plate which is received at an open end of an axle housing. The separate bearing support plate supports the bearing at the open end, and is received within the open end of the axle housing. In the prior art, the large helical cover typically also provided the bearing support. The use of the separate bearing support plate allows the modular assembly of the axle assembly and further facilitates repair. In another feature of this invention, a threaded adjustment member is associated with both the bearing at the open end of the differential, and also with the bearing at the other end of the differential. The threaded adjustment members allow the control of gear positioning and the pre-load on the bearings such that precise positioning and pre-load adjustment are easily obtainable.Type: GrantFiled: January 23, 1995Date of Patent: December 16, 1997Assignee: Rockwell Heavy Vehicle Systems, Inc.Inventors: Malcolm F. Ruppert, Jr., William C. Sullivan

Patent number: 5687973Abstract: A seal is provided on a slinger for a pinion shaft in an axle housing. The seal provides sealing contact at a location between the bearing cage and the slinger. The slinger prevents relatively large dirt, stones, and debris particles from reaching an inner oil seal. The seal on the slinger prevents smaller particles from reaching the oil seal. Several embodiments of the seal are disclosed.Type: GrantFiled: June 24, 1996Date of Patent: November 18, 1997Assignee: Rockwell Heavy Vehicle Systems, Inc.Inventor: Malcolm F. Ruppert, Jr.

Patent number: 5348570Abstract: A venting mechanism which includes three members. A first member having threads defined thereon connected to a second offering a hexagonally shaped external surface. The third member features a bore which defines an annular surface at the intersection with a bore through the second member. A baffle is located within the bore of the second member by engagement with the annular surface defined between the second and third member. A Gortex film and a wire mesh placed within the bore of the third member are retained by a rolled lip thereof. In this manner, the baffle and the Gortex film act to maintain liquid on one side of the breather while allowing gases to freely pass therethrough.Type: GrantFiled: April 5, 1993Date of Patent: September 20, 1994Assignee: Rockwell International CorporationInventors: Malcolm F. Ruppert, Jr., Eric C. Liu
