A dual-wheel differential system includes an in inner hub, an outer hub, and a differential assembly mechanically coupled between the inner hub and the outer hub to allow the inner hub and the outer hub to rotate at different angular speeds. A user-actuatable locking system is configured to mechanically lock the inner hub to the outer hub. The user-actuatable locking system may include at least one axially-translating or radially-translating locking pin configured to engage at least one of the inner hub and the outer hub. The locking system may be pneumatically, hydraulically, or electromechanically actuated.

Systems and methods for improved differential locks

The subject invention provides a wheel assembly () having a spindle () for attachment to a vehicle along a rotational axis (R). An electric motor () is disposed radially about the spindle () and includes a stationary stator () and a rotor () rotatable about the rotational axis (R) relative to the stator (). A rotor support () is disposed about the spindle () and includes a collar () rotatably supported by at least one rotor support bearing () on the spindle (). The rotor support () includes a flange () disposed within a predetermined axial distance (D) and extending radially outward from the collar () to support the rotor (). A planetary gear system () interconnects the rotor support () and a wheel drive () for reducing rotational speed of the rotor () and increasing the torque of the wheel assembly ().

Wheel assembly with integral electric motor

A high ground clearance drive assembly includes a drop box and an articulation drop box. The drop box is fixed to the vehicle frame and the articulation drop box pivots relative thereto as a suspension system is exercised. The articulation drop box is pivotable about a pivot pin which extends through both the articulation drop box and the drop box to provide an axial preload therebetween. A first chain interconnects an input sprocket on the input shaft and an intermediate sprocket assembly. A second chain interconnects a second intermediate sprocket and the output sprocket to drive an output shaft connected thereto. A hollow shaft supports the first and second intermediate sprockets about the pivot pin such that rotation of the articulation drop box relative the drop box is accommodated without additional complex structure.

Drive assembly for a high ground clearance vehicle

A wet disc brake and axle fluid cooling assembly is disclosed which is driven by a vehicle's axle shaft. The system comprises a brake housing, an axle shaft connected to the brake housing wherein the brake fluid can flow between the brake housing and the axle housing, an internal pump connected to the axle housing, and an external cooling tube disposed between the internal pump and the brake housing. An axle shaft is rotatingly disposed within the axle housing. A first spur gear is connected to and rotates with the axle shaft. The internal pump is comprised of an axle straight tee fitting, a pump rod rotatingly connected to the tee fitting, a propeller connected to and rotating with the pump rod that draws the fluid from either the axle housing or the brake housing, and a second spur gear that engages with the first spur gear. The axle shaft drives the pump rod as the shaft rotates, either clockwise or counter-clockwise.
