Abstract: A structural electric tandem axle module (13) for propelling a vehicle such as a large vocational vehicle without applying torque to the chassis frame of the vehicle as the module operates.

Abstract: A vehicle includes a front axle and rear axle, where at least one of said axles is driven, an engine arranged in the vicinity of the rear or front end of said vehicle, the engine including an output shaft connected to the driven axle via a transmission system for transmitting driving power from the engine to the driven axle. The transmission system includes at least a multiple-speed gearbox for causing variable gear ratio between the engine and driven axle. The engine and at least a part of the gearbox are arranged on each side of the driven axle, and are connected only via a power transmitting device so that an engine block of the engine is separated from a gearbox housing of the gearbox.

Abstract: A control system for a vehicle having first and second wheels is provided that includes a differential apparatus adapted to distribute torque between the first and second wheels and a traction controller for controlling operation of the differential apparatus from vehicle launch up to a predetermined vehicle speed. The traction controller is configured to engage the differential apparatus in a first operating state according to at least one vehicle operating parameter indicative of a low traction operating condition and to further control engagement of the differential apparatus in a second vehicle operating state during the low traction operating condition according to a difference between an actual vehicle yaw rate and a predetermined target vehicle yaw rate. The control system also includes a stability controller for controlling engagement of the differential apparatus at or above the predetermined vehicle speed.

Abstract: A hearse assembly includes a support frame that has a substantially rectangular shape and has a forward end and rearward end. A tricycle frame includes a motor and has a back portion and a front portion. The back portion is integrally coupled to the forward end. A steering column and wheel combination is coupled to the front portion. A first axle is mounted on the support frame and is positioned nearer the forward end. A first differential is mechanically coupled to the first axle. A first drive shaft mechanically couples the motor to the first differential. A second axle is mounted the support frame and is positioned nearer the rearward end. The first and second axles each have a pair of free ends each having a wheel attached thereto. A housing is mounted the support frame. A door is positioned in the housing for selectively opening or closing the housing.

Abstract: A driveline assembly module includes a drivetrain assembly that is a rigid, substantially box-like member, that is the main support structure for all the driveline components. An independent suspension system having an associated wheel hub is also attached to the drivetrain assembly. By mounting the driveline components and independent suspension as an integral module, the components are replaced or serviced by replacement of the entire module. Thus, the individual mounting, replacement and servicing of the individual components, each having multiple independent attachment points, is avoided.

Abstract: An articulated truck for carrying a load through a plurality of work cycles is disclosed. An embodiment includes a frame assembly, an articulation. joint, a plurality of axles, a plurality of ground engaging devices, an operator compartment, a body, an engine, a transmission and an apparatus for receiving the torque and transferring the torque to a plurality of drive shafts. The apparatus includes a plurality of gears, an inter-axle differential, and a plurality of drive shafts. The inter-axle differential is located such that the front axle may be suspended to allow oscillation.

Abstract: The invention is directed to a vehicle drive/suspension system that has a chassis having a front and rear portion and a pair of sides. A drive axle has opposed end portions and extends between the sides. Each side has a pivotally mounted elongated rocker arm that is connected to the corresponding end portion of the drive axle. Pivot mounts and pivot plates are used for this attachment. The rocker arms have sprockets mounted to each end. These sprockets are chain driven by drive sprockets located at each end of the drive axle. Tension sprockets are slidably mounted onto each rocker arm. Also associated with each rocker arm is a damper, and a rubber stop member. It is preferred that the pivot location of each pivot mount is away from the center point of the rocker arm.
