Filed:

Jul 30, 2010

Appl. No.:

12/847034

Inventors:

Brian M. Clark - Seattle WA, US
Mark Case - Duvall WA, US
Rainer Leuschke - Seattle WA, US

Assignee:

GENIE INDUSTRIES, INC. - Redmond WA

International Classification:

F15B 11/17

US Classification:

60484

Abstract:

A hydraulic system is provided with a prime mover connected to a first fixed displacement pump having a maximum flow A, a hydraulic loop connected to a system of valves and actuators, a second fixed displacement pump having a maximum flow B in fluid communication with the loop, an electric machine operable as one of a motor and a generator connected to the second pump and electrically coupled to a battery, and a controller connected to the prime mover and the electric machine. The hydraulic loop is in fluid communication with the first pump with a first check valve. The second pump is arranged in parallel with the first pump.

B62D 15/00
B60K 17/30

US Classification:

182 696, 180411, 180253, 414718

Abstract:

A vehicle is provided with a chassis having a footprint, a load carrying structure, and a support assembly coupling the chassis and the structure. The support assembly is adapted to move the structure relative to the chassis between a stowed position and a deployed position outboard of the footprint of the chassis. A plurality of wheels is configured to roll on the support surface and a plurality of axles coupling the wheels to the chassis are provided. Each axle includes at least one spindle supporting an individual wheel for rotation on a spindle axis. A steering system is adapted to position the wheels between driving and rotation arrangements with respect to the chassis such that in the rotating arrangement each of the plurality of wheels rotate relative to the chassis whereby the chassis, the platform and the support assembly may rotate in unison about the steer axis.

US Classification:

180 65265, 318452, 180 6521, 180 65275, 903909

Abstract:

A vehicle is provided with an engine connected to a hydraulic pump in fluid communication with a hydrostatic drive system and at least one of a plurality of traction devices connected to a hydrostatic drive motor. The vehicle also has a battery coupled to an electric machine coupled to at least one of the remaining plurality of traction devices. The electric machine acts as a motor to propel the vehicle or a generator to charge the battery. A vehicle is provided with a hydraulic drive system and an electric drive system each operably connected to a fraction device. Power may be transferable from the first drive system to the second drive system by way of ground coupling between the traction devices.
