An air spring for damping and controlling a level position of a driver's cab or of a motor vehicle includes a lid, a rolling piston and at least one air spring bellows. At least one damping device is integrated into the air spring. A level control system is integrated into the air spring and is configured to at least one of supply and discharge compressed air, gas or a compressible medium so as to control the level position of the driver's cab or of the motor vehicle.

An air spring includes a closing member, a rolling piston, and an air spring bellows connected to the rolling piston and the closing member to form a fluid-filled pressure chamber. A level control system for supplying and/or discharging fluid may be integrated into the pressure chamber to control level position based on air spring stroke. The level control system may have a control valve and an actuator connected to the control valve. The actuator may include a guide tube coupled to the rolling piston or closing member, and movably arranged within the pressure chamber. An actuating member may include a pin member and may operate the control valve. A compression spring may have a central spring and a biasing spring, and the guide tube may include a control flange coupled to the pin member, and the biasing spring may be supported to press the pin member against the control valve.

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 suspension system for a work vehicle includes a shock absorber including a fluid, a coil positioned at least partially in the fluid, a sensor configured to detect a work status of the work vehicle, and a controller. The controller is configured to determine the work status of parked or operational based on the sensor, determine an electrical resistance of the coil in a shock absorber based on the work status, predict a temperature of a fluid in the shock absorber based on the electrical resistance of the coil, provide an electric current in the coil based on the predicted temperature of the fluid, determine the electrical resistance of the coil while the electric current is on, and terminate the electric current in the coil based on the work status and the predicted temperature.

An overland vehicle is provided which includes a chassis with a roll-over protection structure, a powertrain configured to generate power to drive the overland vehicle, a first suspension system configured as a chassis to ground suspension system, and an operator compartment. The vehicle may also include a second suspension system configured to pneumatically suspend the operator compartment within the chassis, where the second suspension system includes a plurality of pneumatic couplers, including at least a first pneumatic coupler suspending the operator compartment to the chassis along a first vector extending in a first direction, and a second countering pneumatic coupler suspending the operator compartment to the chassis along a second vector extending in a second direction, where the second direction is generally opposite the first direction. In another embodiment, the second suspension system may include a plurality of spaced apart pneumatic couplers, including at least a first pneumatic coupler suspending the operator compartment to a first side of the chassis, and a second pneumatic coupler suspending the operator compartment to a second side of the chassis.

A method for performing open-loop or closed-loop control of a driver's cab mount of a motor vehicle, wherein the driver's cab mount has dampers whose damper force can be adjusted, wherein the motor vehicle can be operated in a first driving mode in which the motor vehicle automatically carries out vehicle guidance comprising both a longitudinal guidance operation and a transverse guidance operation of the motor vehicle, and in a second driving mode where the motor vehicle can be controlled by the driver, in which driving mode a driver of the motor vehicle is intended to carry out at least part of the vehicle guidance, wherein when the motor vehicle is operated in the first driving mode, the adjustable dampers of the driver's cab mount are actuated or adjusted in such a way that pitching or rolling movements are reduced compared to the second driving mode.

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 work vehicle includes a cab, a body frame and a restrictor. The body flame includes a base component, and a support frame provided on an upper side of the base component. The support frame supports the cab. The restrictor is provided to a floor frame of the cab. The restrictor is disposed between the base component and the floor frame. The restrictor includes a retaining member disposed on a lower side of the support frame, and an impact absorber disposed on a cab side of the retaining member.

Systems and methods for compensating for displacement-related sensor mismatch of an autonomous vehicle are provided. An autonomous vehicle can define a pitch axis and a roll axis. The pitch axis can be perpendicular to the roll axis. A system can include one or more processors, and one or more tangible, non-transitory, computer readable media that collectively store instructions that when executed by the one or more processors cause the computing system to perform operations. The operations can include obtaining data indicative of a displacement of a first portion of the autonomous vehicle relative to a second portion of the autonomous vehicle. The operations can further include determining an orientation of the first portion relative to the second portion about at least one of the pitch axis or the roll axis based at least in part on the data indicative of the displacement.

A cab and hood suspension system includes a cab suspension system, a hood suspension system, and a hood tilt system. The cab suspension system includes supporting spring elements and cab linkage configured to control movement of a cab relative to a chassis. The hood suspension system includes hood linkage configured to locate the hood relative to the chassis. The hood linkage is configured to match the movement of the cab linkage. The hood tilt system is provided by the hood linkage of the hood suspension system.
