A vehicle wheel positioning and steering apparatus particularly useful for aerial work platforms comprises a support chassis and chassis support legs pivotally connected to the chassis. Steerable wheel assemblies are operably connected at ends of the support legs and powered actuators are operably connected to the chassis and legs for pivotally moving the legs and wheel assemblies relative to the chassis between transport and working positions. Variable length linear wheel steering actuators comprise one link of four bar parallelogram steering linkages between the chassis and wheel assemblies and the support legs each comprise second bars of the four bar parallelogram steering linkages.

The vehicle includes: a chassis which includes a front cross-member and a rear cross-member; a nacelle receiving a person or a load, pivotally mounted relative to the central part of the cross-members about a substantially longitudinal hinge axis, the center of gravity of the nacelle being situated below said hinge axis; a front train and a rear train, each including two movement supports on the ground, each movement support being connected to the end part of the corresponding cross-member by a connecting system; the cross-members, situated in the upper part of the nacelle, being separate pieces linked together only by the nacelle, via the hinge axis, so as to be able to pivot about the hinge axis independently of one another.

A corner module apparatus for a vehicle includes a driving unit configured to provide driving power to a wheel of the vehicle; a braking unit, coupled with the driving unit, configured to apply or release braking power; an upper arm module, connected to the driving unit, adjustable to vary a camber angle of the wheel; a lower arm module, connected to the driving unit, configured to absorb road surface impact while the vehicle moves; and a steering unit configured to support the upper arm module and the lower arm module, and adjust a steering angle of the wheel.

A working machine comprising a chassis; first and second elongate support members, each elongate support member being pivotally coupled to the chassis at a respective pivot point; a first wheel assembly coupled to the first elongate support member and a second wheel assembly coupled to the second elongate support member; a first linear actuator coupled to the first elongate support member and a second linear actuator coupled to the second elongate support member, wherein the elongate support members are movable by operation of the actuators between a stowed configuration and a deployed configuration. A distance between the first and second wheel assemblies is greater in the deployed configuration than in the stowed configuration. The first and second linear actuators are pivotally coupled to the chassis along a common pivot axis.

A slider suspension system for a heavy-duty vehicle includes a slider assembly with a main member that is movable relative to a primary frame of the heavy-duty vehicle in a first direction along the extent of the main member. The main member has a first portion and a second portion extending transverse to the first portion. A friction reducing slider wear pad is fixed to the main member and interposed between the main member and the primary frame. The friction reducing slider wear pad has a first segment fixed to the first portion of the main member. The friction reducing slider wear pad also has a second segment engaging at least a part of the second portion of the main member to inhibit movement of the friction reducing pad relative to the main member in a second direction transverse to the first direction.

A method of operating a construction machine that includes a base, support arms each pivotally coupled to the base, and a plurality of wheel assemblies each coupled to the one of the support arms, the method including, in a transport mode of the construction machine, turning a wheel of each of the wheel assemblies, independently from a wheel of another of the wheel assemblies, to a toe out orientation. The method also includes driving each support arm to a deployed condition of the support arm in an operational mode of the construction machine. Driving each support arm to the deployed condition causes the distal ends of each of the support arms to move away from one another and outwardly from the base. The method also includes locking each support arm in the deployed condition and controlling steering of each wheel in the operational mode of the construction machine.

A cargo vehicle includes a composite floor assembly configured to support cargo, at least one wheel assembly configured to transport the cargo on the composite floor assembly, a suspension assembly associated with the at least one wheel assembly, and an intermediate adapter assembly. The intermediate adapter assembly is permanently coupled to the composite floor assembly and removably coupled to the suspension assembly such that the composite floor assembly is removably coupled to the suspension assembly.

A trailer slider suspension including a tubes and wires support system. The slider includes a frame slideably coupled to and supporting a trailer. Axles are pivotally secured to the frame. Air springs are provided between the axles and stop plates on the frame. The air springs include bearing plates abutting the stop plates. The bearing plates include fasteners which extend through corresponding holes in the stop plates. Supporting brackets are secured to the frame with the bearing plates fasteners extending through corresponding securement holes in the brackets and nuts threadingly received thereon, thereby clamping the brackets between the nuts and stop plates. The brackets include support holes wherethrough the tubes and wires are received and supported. A main brace is secured between the stop plates and the frame and side braces are secured between the stop plates and the main brace. The brackets include walls or slots engaging the braces.

A suspension module for supporting a vehicle chassis includes a module frame pivotably connected to an axle on the chassis and a wheelbox mounted to the wheel and slidingly coupled with the module frame by strut rods. The wheelbox and module frame pivot in unison with respect to the chassis, and the module frame is configured to move between a standard position and a high clearance position relative the wheelbox. The suspension module includes an adjustment actuator coupled with the module frame to shift the frame between the operating positions. The strut rods move from a first position in which bottom ends of the first and second strut rods are below the wheelbox when the module frame is in the standard position to a second position in which the bottom ends are in a higher position relative the first position when the module frame is in the high clearance position.

A machine includes a chassis, a plurality of ground engaging elements supporting the chassis above a ground surface, a motor for driving at least one of the ground engaging elements and a plurality of assemblies supporting the chassis on the ground engaging elements. Each of the assemblies is configured to selectively raise and lower the chassis relative to the ground surface and includes a first attachment component for attaching the assembly to one of the ground engaging elements, a second attachment component for attaching the assembly to the chassis, an adjustment component for shifting the first attachment component between a plurality of operating positions relative to the second attachment component. A control system allows an operator to remotely control the adjustment components of each of the assemblies.
