Abstract:
A system and method for adjusting the tread width of a vehicle. The vehicle has a swing arm on each wheel, each activated by its own hydraulic cylinder. The vehicle's tread can be adjusted by pivoting the swing arms. The swing arms are each provided with two actuators, one to maintain the proper toe angle of the wheels as the swing arms move, and one to steer the vehicle.
Abstract:
A system and method for raising and lowering a vehicle. The system includes a four-bar linkage provided for each wheel. The four-bar linkage includes a first three linkage assembly and a second three linkages assembly. The first three linkage assembly maintains the orientation of the vehicle relative to the wheel during the lifting and lowering while the second linkage assembly provides the power to lift and lower the vehicle. Power provided by a hydraulic cylinder is pivotably coupled to the second linkage assembly. A steering assembly is provided between the four-bar linkage assembly and the wheel. The four-bar linkage vehicle lifting assembly may be provided on agricultural vehicles, construction vehicles, or any desired vehicle.

Abstract:
A system and method for providing suspension for a ride height adjustable vehicle. The vehicle has a four-bar linkage assembly coupled between to the frame and wheel of the vehicle. A linear actuator coupled to the four-bar linkage assembly raises and lowers the ride height of the vehicle. An airbag is also coupled to one of the linkages to provide suspension. The airbag and linear actuator are coupled to one another by a pivotable plate. The airbag and linear actuator co-act to provide suspension for the vehicle across all ride heights.
Abstract:
A system for planting cover crop seeds in fields with standing row crops. A high-clearance agricultural vehicle is provided with a high-clearance toolbar. A plurality of ground-engaging arm assemblies depend from the toolbar. The toolbar is provided with a plurality of seeders that may be provided on the arm assemblies. The arm assemblies are provided with trailing portions to which are attached soil sealers. The system travels through the field, delivering seeds between rows of standing crops. The soil sealers cover the seeds with soil.
Abstract:
A system and method for adjusting the tread width of a vehicle. Each wheel of the vehicle is provided with two actuators: one toe actuator to adjust the toe angle and one steering actuator to steer the wheel. The toe actuators and steering actuators counterpose each another. The vehicle is configured to actuate the toe actuators to simultaneously turn the wheels on opposite sides of the frame in opposite directions relative to one another, and to actuate the steering actuators to simultaneously turn wheels on opposite sides of the frame in the same direction as one another.

Abstract:
A system for planting cover crop seeds in fields with standing row crops. A high-clearance agricultural vehicle is provided with a high-clearance toolbar. The system is provided with soil sealers. A seeder with a reciprocating seeder is provided above the soil sealers to deliver various types of seeds onto the disrupted soil, after which the soil sealers cover the seeds with soil.
Abstract:
A permanent magnet rotor for an electrical generator includes a rotor shaft and a rotor core mounted coaxially upon the rotor shaft. The rotor core defines a plurality of longitudinal core passages which include a segment of a rotor cooling circuit, and further includes a permanent magnet outer core component mounted on an inner core component and including a plurality of permanent magnets. A cooling liquid containment mechanism for the permanent magnet rotor includes a first liquid containment cover coupled to the inner core component and a second liquid containment cover coupled to the inner core component. The liquid containment covers are configured to contain cooling liquid passed from an inlet segment of the rotor cooling circuit defined by the rotor shaft into the plurality of longitudinal core passages, and thenceforth into an outlet segment of the rotor cooling circuit also defined by the rotor shaft. The liquid containment covers are mounted on the inner core component at locations radially inward of a cylindrical outer surface thereof.
