Patent number: 7255187Abstract: The inventive parallel drive system is particularly well suited to be supported at the axle of the vehicle. A coupling arrangement includes a clutching mechanism and a gear reduction device that selectively couple an electric motor to the drive wheels for providing torque to the wheels alone or in combination with input from an internal combustion engine. The drive torque can also be provided exclusively from the internal combustion engine. The inventive arrangement also allows for the electric motor to be used as a generator during coasting or braking, for example.Type: GrantFiled: February 11, 2005Date of Patent: August 14, 2007Assignee: ArvinMeritor Technology, LLCInventors: Dale K.

Patent number: 6904988Abstract: A drive train assembly including an electric motor mounted to the frame of the motor vehicle and a trailing arm. The trailing arm is attached to the frame of a motor vehicle such that a pivot point is common to an axis of rotation of a shaft of the electric motor. The electric motor drives a drive mechanism supported by the trailing arm to drive a wheel suspended at a distal end of the trailing arm. The trailing arm pivots about the axis of rotation of the motor shaft thereby reducing the suspended mass of the vehicle and improving ride and handling characteristics.Type: GrantFiled: December 27, 2002Date of Patent: June 14, 2005Assignee: ArvinMeritor Technology, LLCInventors: Clive Harrup, Dennis A.

Patent number: 6812663Abstract: A vehicle drive assembly includes an electric motor directly coupled to a rotatable member for driving a wheel, for example, without gear reduction assemblies between the motor output and the driven wheels. A multi-phase, high pulse current stepper motor is used as the motor in one example. A driven wheel is supported by a wheel mounting member in a conventional fashion. A rotatable member associated with the wheel mounting member is directly coupled to an output of the stepper motor. The stepper motor can selectively operate in several modes. A first mode provides driving torque to the vehicle wheels, a second mode provides a braking force and an optional third mode allows the stepper motor to serve as a parking brake.Type: GrantFiled: March 26, 2003Date of Patent: November 2, 2004Assignee: ArvinMeritor Technology, LLCInventors: Dennis A. Kramer, Dale K. Bell, Clive Harrup, Mehmet S. Ciray, Silvio M. Yamada, Dean M. House, David K. Platner, Dale J. Eschenburg

Patent number: 6794772Abstract: An electric motor assembly is provided that includes a housing. A rotor is arranged in the housing and is rotatable about an axis. A vehicle wheel is coupled to the rotor. The rotor has an annular profile defining sinusoidal teeth and is generally concentric with the axis. The angle and number of oblique surfaces of the teeth and the diameter of the rotor, in part, define the speed and torque of the rotor. A plurality of electric linear actuators are arranged circumferentially about and generally parallel to the axis. The actuator includes shafts having ends that engage the profile. The shafts are movable between extended and retracted positions to rotate the rotor in a desired direction. A sensor detecting the position of the rotor and a controller may be used to effect the desired rotation.Type: GrantFiled: April 15, 2003Date of Patent: September 21, 2004Assignee: ArvinMeritor Technology, LLCInventors: Dale K.

Publication number: 20040089485Abstract: An electric motor assembly for providing driving torque to a wheel on a vehicle includes a plurality of different sized motors. The motor having the largest outside dimension or outside diameter is placed closest to the wheel hub to provide the largest possible motor size within typical vehicle packaging constraints. A plurality of motors is used to achieve a desired torque level at the wheel. In one example, multiple motors are positioned near each wheel with the size of the motors decreasing from a lateral side of the vehicle toward the centerline of the vehicle. Motor control strategies for achieving different torque levels and providing selectively regenerative effects are disclosed.Type: ApplicationFiled: November 8, 2002Publication date: May 13, 2004Inventors: Dennis A.

Publication number: 20040089486Abstract: A power producing assembly for a vehicle includes a generator to control energy produced during movement of the vehicle and a hydrolysis system powered by electrical energy produced by the generator to separate water into hydrogen and oxygen. Hydrogen and oxygen are then routed to a fuel cell to produce electrical energy. Hydrogen may also be used in a combustion engine which bums the hydrogen gas. Gases used by the energy producing fuel cell or combustion engine are recovered and recombined to form water for reuse by the hydrolysis system.Type: ApplicationFiled: November 13, 2002Publication date: May 13, 2004Inventors: Clive Harrup, Dennis A.

Patent number: 6707268Abstract: A system for providing driving torque to wheels on a vehicle includes an electric motor having the capability of independently driving rotatable axle shafts. One example includes a single stator with a first armature associated with a first axle shaft and a second armature associated with a second axle shaft. A controller independently controls power to the armatures to achieve the desired wheel speed or driving torque at each of the wheels.Type: GrantFiled: October 15, 2002Date of Patent: March 16, 2004Assignee: ArvinMeritor Technology, LLCInventors: Dale K.
