Abstract: A selectively switchable dual rate vehicle suspension system comprising a pushrod actuated inboard spring configuration, conventionally oriented between the unsprung mass and the sprung mass of one corner of the vehicle, comprising a torsion bar spring of a first predetermined rate, K1, and a coil spring of a second predetermined rate, K2, arranged in series so as to provide a total combined spring rate KT. A lockout actuator is arranged in parallel with the coil spring and configured so that in a first mode it allows the coil spring to move freely and in a second mode prevents motion of the coil spring such that when the lockout actuator is in a first, unlocked, mode the overall vehicle suspension spring rate is defined by the series equation 1/ KT = 1/K1 + 1/K2, and when the lockout actuator is in a second, locked, mode the overall vehicle suspension spring rate is substantially higher as defined by KT = K1, thus selectively providing both a low rate, optimal ride comfort setting and a high rate, optimal handling setting.

Abstract: A vehicle suspension system (55) is configured so as to contain all of the suspension motion control elements completely within the volume of the road wheel (100) while remotely locating the energy storage device (45) and damping device (42). An upright (60) comprises the spindle (61), brake caliper (105), and structure to hold a main strut shaft (70) parallel to a secondary strut shaft (67). The suspension's motion is controlled by the shafts which slide relative to the sprung part of the vehicle (1). The main strut shaft (70) includes a pumping piston (73). The fluid (91) displaced by the pumping piston (73) flows through a hydraulic connection (47) to a remote suspension module (40) mounted to the sprung part of the vehicle. The remote suspension module (40) hydraulically transmits the wheel motion to the remote energy storage device (45) and damping device (42). A steering arm (95) rotating around the main strut shaft (70) is configured to allow both struts (70 and 67) to slide through it, thus eliminating bump steer.

Abstract: A structural attachment system for a cargo management system is fully integrated into the cargo bed side walls of a pick-up truck so that the only feature that is different than a standard pick-up is an array of holes along the top of the cargo bed side walls. The cargo management system also includes a wide range of different pick-up truck carg o bed mounted accessories that incorporate structural hooks that are adapted to be retained and released by the structural attachment system. Additionally, the structural attachment system provides a single point, simple method of retention and release via a n actuation handle at the rear most point of the pick-up truck cargo bed. The configuration of the structural attachment system allows significant structural retention forces to be transferred from the accessories into the pick-up truck cargo bed side walls via the structural hooks.

Abstract: An auxiliary hydraulic system for vehicles, in particular pick-up trucks, is configured to supply hydraulic fluid under pressure to both on-board and off-board auxiliary equipment such as snow plows, dump boxes and wood splitters. The auxiliary hydraulic system includes a multi-piston fluid pump with electrically selectable poppet valves and an associated microprocessor control that facilitates variable output so that a desired proportional flow can be supplied to the auxiliary equipment. The system also provides a switchable valve arrangement for directional control and an arrangement of fluid distribution pipes and detachable couplings so that a range of different auxiliary equipment can be quickly and simply connected to the system. A simple user interface is also included so that the operator can command the auxiliary equipment from either within or in close proximity to the vehicle.
