A lifting arrangement for lifting a wheel axle of a vehicle comprising a first elongated member extending along a first axis comprising a vehicle frame coupling portion for connecting the lifting arrangement to a vehicle frame of the vehicle during use, a second elongated member extending along a second axis comprising a wheel axle coupling portion for connecting the lifting arrangement to the wheel axle of the vehicle during use, wherein the vehicle frame coupling portion and the wheel axle coupling portion are offset from each other by a length and wherein the lifting arrangement is arranged to adjust the length between a maximum length and a minimum length by axially moving the second elongated member along the second axis relative the first elongated member, wherein the lifting arrangement further comprises an engaging device for axially moving the second elongated member along the second axis relative the first elongated member.

Driven lift axles and associated systems and components are provided for use on heavy duty trucks, trailers, and/or other vehicles. Driven lift axle systems may include one or more motors mounted to the lift axle to provide torque to drive one or more wheels of the lift axle. Various mounting configurations of such motors are possible, such as arranging a motor on the axle to provide torque at a conventional driveshaft input by interfacing with a differential drive gear, positioning a motor at each of the wheel ends of the axle to provide torque directly to the wheels, etc. Each wheel can be driven by a separate motor, allowing for independent control of the torque applied to each wheel. Lift axles described herein can be suitable for use with various motors capable of applying torque to the axle and/or wheels, such as electric motors, hydraulic motors, internal combustion engines, etc.

A high-performance sports car having: a chassis; a bottom facing a ground on which the sports car moves; four wheels supported by the chassis; four suspensions, each of which connects a corresponding wheel to the chassis, has a variable geometry, and is equipped with at least one actuator device adapted to modify the geometry of the suspensions; and a body which covers the chassis and is equipped with four wheel arches, each of which surrounds a corresponding wheel at the top. The chassis is provided inferiorly with a plurality of support feet which are adapted to rest on the ground to support the weight of the sports car. The actuator devices are configured to lift, only when the sports car is parked, the wheels upwards with respect to the chassis changing the geometry of the suspensions up to rest on the ground the support feet i.e. until the wheels detach from the ground.

A vehicle suspension assembly includes a trailing axle carried by a frame of the assembly. The frame can retract to a retracted state from an extended state and extend from the retracted state to the extended state. The retraction and extension can occur along a longitudinal axis of the frame. An operator can pivotally raise and lower a free end of frame in the retracted or extended state along an arcuate path when the vehicle suspension assembly connects to a vehicle.

There are provided an apparatus and a method for controlling a variable axle for preventing a safety accident. An apparatus for controlling a variable axle that controls operation power to one switch which is short-circuited or opened according to a manipulation of a user, and supplies the operation power for a descent of a pusher axle, includes: the other switch having one end connected to power of a vehicle and the other end which is short-circuited or opened in response to a control signal, to thereby supply the power of the vehicle as the operation power at the time of the short-circuit; and a controller confirming whether or not the vehicle is remotely being started when an ignition of the vehicle is turned-on, and opening the other switch by the control signal in the case in which the vehicle is remotely being started as a result of the confirmation.

A retractable wheel assembly includes arm assemblies, wheels, a retraction arm, and a threaded shaft. The arm assemblies are hingedly attached to a lower frame of a utility vehicle. Each arm assembly comprises a first arm, a second arm, and a third arm hingedly linked there between. Each wheel is connected to the third arm of each arm assembly. The retraction arm is connected to the second arm, and a threaded shaft. The threaded shaft is configured to be actuated rearwardly where the retraction arm is rearwardly pulled causing the second arm to unfold the arm assembly outwardly and deploy the wheels and for motion of the utility vehicle. Then, the threaded shaft is configured to be actuated forwardly where the retraction arm is pushed forward causing the second arm to fold the arm assembly inwardly and fold the wheels and when the utility vehicle is positioned at rest.

A pressure system of a suspension device for an amphibious vehicle includes: a pump configured to discharge a working fluid; a first control valve disposed in a first flow path extending between the pump and a first hydraulic chamber, the first control valve being configured to control supply of the working fluid from the pump to the first hydraulic chamber; a pilot check valve disposed in a portion of the first flow path which extends between the first hydraulic chamber and the first control valve, the pilot check valve being configured to open and close the first flow path in accordance with a pilot pressure; and a second control valve disposed in a pilot flow path extending between the pump and the pilot check valve, the second control valve being configured to control supply of the pilot pressure to the pilot check valve.

A method and apparatus for lowering the height of a wheeled vehicle for cargo height constraints during transportation. The rear leaf spring shackle on each side of the vehicle is connected to a sliding frame mount. In the transport configuration, fasteners are removed from the sliding frame mount, and the mount slides forward, rotating the rear leaf spring shackle from a near vertical to a near horizontal position, effectively lowering the height of the vehicle. To return the vehicle to the ride configuration, a screw jack member is attached to the sliding frame mount and a rear attachment point on the vehicle, pulling the sliding frame mount back, aligning attachment points of the mount with the frame member in the original position. The fasteners are reinstalled to lock the sliding frame mount into the ride configuration.

A pivotable wheel mount assembly may include a mounting bracket and a swing arm coupled to the mounting bracket. The swing arm may be movably coupled to the mounting bracket or the trailer and to a wheel and/or suspension so as to enable the wheel to be rotated from a downward or operational position to a horizontal or stowed position. The assembly may include an actuator support bracket coupled to the mounting bracket and an actuator that provides mechanical assistance moving the wheels between positions. One or more locking mechanisms may be provided to secure the assembly in either the operational position, the stowed position, or both.

The present disclosure relates to shipping and storage containers. Specifically, the present disclosure relates to shipping and storage containers, which are traditionally stationary, converted to easily-portable containers. More specifically, the portable containers include a deployable/retractable landing/moving apparatus, a removable tow bar assembly, and leveling support systems. The portable containers can have many uses including as temporary to permanent housing, office space, and school rooms, or to house equipment for use in mobile telecommunication networks and systems, including cellular towers that can be set-up in both permanent and temporary locations.
