A transforming top drive vehicle having a passenger compartment and a separable base is disclosed. One or more hydraulic cylinders are positioned between the compartment and the base to provide force sufficient to raise the compartment. Concentric pipes having sufficient strength to support the compartment are installed with one end connected to the vehicle's base and the other connected to the passenger compartment. The vehicle allows ease of access and the ability to lower the vehicle's center of gravity when navigating rough or uneven terrain and, when the operator is interested in obtaining a better view of wildlife or otherwise increase the field of vision, the passenger compartment can be raised either incrementally or to its fully raised position.

A hydraulic excavator includes a revolving frame forming a support structure, a cab that is disposed to be positioned on a front side of the revolving frame and in which an operator gets, and a plurality of vibration isolating members that are disposed between the revolving frame and the cab to support the cab on the revolving frame in a vibration isolating state. Further, an intermediate connecting member is disposed for connection between the revolving frame and the vibration isolating member and for a height position adjustment of the cab to the revolving frame. The intermediate connecting member is fixed to the revolving frame from a lower side.

A vehicle vibration dampening mount assembly includes a housing, a resilient material, a sleeve and a solenoid. The resilient material has an outer portion attached to an interior surface of the housing and defines first and second chambers with a fluid passage extending therebetween. The sleeve is disposed within the housing and is attached to a central portion of the resilient material extending from a first end to a second end of the housing. The solenoid has a fixed portion mounted to the first end of the housing and a movable portion fixedly attached to the sleeve for movement therewith. The fixed portion has an electromagnetic coil arranged concentrically around the movable portion. The solenoid is configured to selectively move the moveable portion, the sleeve and the central portion of the resilient material in response to electrical current being provided to the electromagnetic coil.

A vibration isolator includes a housing forming an internal cavity, an elastomeric diaphragm within the internal cavity, the elastomeric diaphragm combining with a first end of the housing to form an air spring within the internal cavity, a mechanical spring in series with the air spring within the internal cavity; a mount in series with the mechanical spring opposite the air spring, an annular elastomeric stopper between a second end of the housing and the mount, wherein the mount and the annular elastomeric stopper combine to seal the second end of the housing to form a chamber within the internal cavity between the elastomeric diaphragm and the second end of the housing, and a plate seated on the mount within the chamber.

An agricultural machine, preferably a combine harvester, which has a pivoting vehicle cab. The cab is pivotable relative to the main frame of the machine, about an axis of rotation transverse to the direction of travel of the machine. The cab is pivoted to allow an operator to view a front coupling of the machine, to observe the attaching or detaching of a work implement to the front coupling.

A suspension system includes a hydraulic cylinder having a piston chamber in which a piston moves and a rod chamber in which a rod moves. The hydraulic cylinder operably moves between a retraction and an extension. The system also includes a throttle valve, a branching, and a hydraulic reservoir fluidly coupled to the hydraulic cylinder. A fluid flow from the piston chamber is divided at the branching into a first fluid flow portion and a second fluid flow portion. The first fluid flow portion flows to the rod chamber of the hydraulic cylinder, and the second fluid flow portion flows through the throttle valve to the hydraulic reservoir.

A control device of a vehicle suspension has a suspension device mounted between a supporting vehicle structure and a vehicle part that is movably mounted. The control device includes a blocking device for blocking a compression or rebound motion occurring at the suspension device in correspondence with a blocking command transmitted to a control unit. The control unit determines a characteristic weight value for a current loading of the suspension device when the blocking command is set and stores it as a pertinent value in a memory unit. The control unit determines a value for the weight when the blocking command is reset in order to cancel a blocking of the suspension device according to the result of a comparison with the value stored in the memory unit.

A cabin suspension arrangement for a utility vehicle, having a plurality of trailing arms that extend in a longitudinal direction, by which a driver's cabin is mounted and can pivoted relative to a vehicle frame. Two of the trailing arms are arranged spaced apart from one another in a transverse direction that extends perpendicularly to the longitudinal direction, are connected to one another by a torsion bar spring that extends in the transverse direction, and are arranged at the same height in a vertical direction perpendicular to the longitudinal direction and to the transverse direction, thereby forming a first trailing arm pair. Two other trailing arms are arranged spaced apart from one another in the transverse direction, are arranged at the same height in the vertical direction, and thereby form a second trailing arm pair, which is spaced apart, in the vertical direction, from the first trailing arm pair.

Vehicle vibration device for a vehicle seat or a vehicle cabin, comprising a lower part and an upper part which is resiliently mounted relative to the lower part by a damper means, wherein the upper part is mounted in a suspended manner on the lower part by means of at least one pivot bearing, wherein the at least one first pivot bearing comprises at least one first lever, the first end of which is attached to the lower part by a first pivot axis and the second end of which is attached to the upper part by a second pivot axis, wherein the second end is located below the first end when viewed in a vertical direction, wherein at least the position of the first end of the lever can be changed by an adjustment means.

Vehicle cab suspension control systems are disclosed herein. In some embodiments, the cab suspension control systems can include front cab-to-frame mounts that include controllable elastomer-based isolators that can provide real time variable damping to improve ride quality and/or road holding and reduce cab roll in response to, for example, input from one or more cab and/or frame mounted accelerometers, position sensors, etc. Embodiments of the control systems described herein can utilize a single vehicle controller (e.g., an ECU) to control all of the cab suspension components (e.g., semi-active damping technologies, air spring technologies, etc.) employed on a vehicle to provide a single suspension control solution that can provide improved ride performance, road holding, etc.
