An operator station suspension system including isolators, a butterfly crossbar and station connection locations located on the butterfly crossbar. The butterfly crossbar includes a central crossbar that extends laterally with forward extending arms rigidly connected at the left and right ends, and rearward extending arms rigidly connected at the left and right ends of the central crossbar. The butterfly crossbar couples to the operator station at the station connection locations with one of the isolators located between the butterfly crossbar and the operator station at each of the station connection locations to reduce noise and vibration. Each connection location can have a connection post, and the isolators can be ring-shaped to fit over the connection posts. The suspension system can also include shock dampers for vertical movement, control linkages for pitch motion, and/or stabilizer linkages for roll motion of the subframe structure relative to the chassis.

A lift apparatus is provided for use with a vehicle comprising a first frame and a second frame. The lift apparatus comprises a spindle, a bearing, a cylinder, a snap ring, and a bearing retainer. The spindle is configured to be attached to the second frame so as to extend therefrom in spaced apart relation to the first frame. The bearing is positioned on the spindle. The cylinder is configured to be attached to the first frame and is attached to the second frame to move the first frame relative to the second frame. The cylinder is positioned on the bearing such that the bearing enables movement between the spindle and the cylinder. The snap ring is attached to the spindle. The bearing retainer is positioned on the spindle between the snap ring, and the bearing retains the bearing on the spindle.

An operator station suspension system including a subframe structure with connection locations, isolators, and suspension components to couple the subframe structure to a chassis and enable movement of the subframe structure relative to the chassis. The subframe structure connects to an operator station at the connection locations with isolators between the subframe structure and operator station at each connection location to reduce noise and vibration. The isolators can be made of rubber, polymer or other materials. Each connection location can have a connection post, and the isolators can be ring-shaped to fit over the connection posts. The suspension components can include shock dampers that enable vertical movement, control linkages that enable pitch motion, and/or stabilizer linkages that enable roll motion of the subframe structure relative to the chassis. The subframe structure can include a rigid body with forward and rearward arms rigidly connected to the rigid body.

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.

Disclosed herein is a mover including a plurality of wheels, a body, and a friction braking mechanism. The body has a bottom surface. The body is supported by the plurality of wheels with the bottom surface facing a traveling surface, and travels on the traveling surface by turning the plurality of wheels. The friction braking mechanism applies a brake on the body with at least a portion of the bottom surface or at least a portion of a movable body brought into contact with the traveling surface by switching, while the body is traveling, a state of the movable body from a first state into a second state. The second state is a state where the movable body protrudes from the bottom surface to a different height from in the first state.

An assembly for enabling rotational motion in a vehicle or mobile working machine is disclosed which includes at least two sections arranged in an overlying position relative to the vehicle's or working machine's working surface. A top section can be led to motion relative to a bottom section and a longitudinal rotation axis, the top section and the bottom section being movably coupled to each other by at least one trajectory element which generates a curvilinear trajectory. The relative motion of the top section and the bottom section proceeds along a curvilinear trajectory in a section plane which is perpendicular relative to the lengthwise rotation axis. The trajectory can be at least partly in the shape of a circular arc, the midpoint of this curvilinear trajectory being disposed below the bottom section. An actuator mounted on the vehicle or working machine affects the top section and/or the bottom section.
