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.

An air spring assembly or air spring damper with an integrated valve control for controlling a level position of a vehicle or of a driver's cab includes a rolling tube, a lid and an air spring bellows which together delimit a pressure chamber with compressed air. A control valve includes an actuation device for feeding compressed air into the pressure chamber or for discharging compressed air from the pressure chamber. A compression spring device has a first end operatively connected to the rolling piston or the lid and a second end operatively connected to the actuation device. The compression spring device is configured with at least two parts including a central spring facing towards the rolling piston or the lid and a control valve biasing spring facing towards the control valve. The central spring is biased to a greater extent than the control valve biasing spring.

An air spring for damping and controlling a level position of a drivers 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.

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 pneumatic suspension system for a vehicle is provided comprising a mounting arrangement for mounting a portion of the vehicle on a chassis; the mounting arrangement including at least one pneumatic spring to be arranged and coupled between the portion of the vehicle and the vehicle chassis. A vehicle state control system is provided that provides a pressure set value in the pneumatic spring and a pressure controller is arranged to a valve device alternatively for pressurizing or depressurizing the each pneumatic spring. The valve device comprises at least a first valve having a valve outlet coupled to the spring terminal and a valve inlet communicatively coupled to the pressure terminal. A support structure (102) distinct from the sealing edge (104) is provided arranged to providing supporting contact to the sealing face to counteract deformations of the sealing face.

A harvester extends along a longitudinal direction, a lateral direction, and a vertical direction. The harvester includes a frame and a grain tank positioned above, and supported relative to, the frame. Moreover, the harvester includes an operator cabin extending between a forward side and an aft side and between an upper portion and a lower portion. The operator cabin is positioned above the frame and forward of the grain tank. Additionally, the harvester includes a coupling member coupling the operator cabin to the frame. The coupling member is mounted to the lower portion of the operator cabin. Furthermore, the harvester includes a damping member coupled between the grain tank and the upper portion of the operator cabin. The damping member is configured to limit motion of the coupling member relative to the frame during operations.

A vehicle has a cab with a cab suspension system. The vehicle includes a chassis and a cab for a driver of the vehicle mounted to the chassis. The cab has an inner structure having a floor supporting a driver seat and an outer structure having a frame surrounding the inner structure. The inner structure and the outer structure are separate and can move relative to the chassis and relative to one another. A suspension system mounting the cab to the chassis includes a first suspension subsystem connecting the outer structure to the chassis and a second suspension subsystem connecting the inner structure to the chassis.

A cabin levelling valve includes a control member, a body, a cover attached to the body, a gasket mounted between the body and the cover, a supply port, a discharge port, and at least one exhaust port. The at least one exhaust port includes a sealing member configured to reduce or prevent ingress of foreign material into the cabin levelling valve. The at least one exhaust port further includes a mounting member affixed to the body or the cover to secure the sealing member to the body or the cover.

A suspension system for a work vehicle can include one or more first support brackets configured to operably couple with a base component. One or more respective retainment brackets configured to operably couple with the one or more first support brackets and a cab. The one or more respective retainment brackets is configured to rotate relative to the one or more first support brackets about a pitch axis. One or more second support brackets is configured to operably couple with the base component. A cab crib is operably coupled with the one or more second support brackets. A suspension cylinder is coupled to the cab crib. A locking assembly is at least partially coupled with the cab crib and configured to selectively retain a cab frame.

A cab mounting including a chassis holder, a cab holder, and at least one flexible element. The chassis holder includes a chassis plate, designed for fastening to a vehicle chassis, and a lower bearing plate, which is fastened to the chassis plate and has an opening. The cab holder includes a cab plate, designed for fastening to a vehicle cab, and an upper bearing plate, which is fastened to the cab plate and has a U-shaped structure, designed to be held movably in the opening of the lower bearing plate, such that the chassis holder and the cab holder are movable relative to each other. The at least one flexible element is fastened to the chassis plate and to the upper bearing plate such that surface contact between the at least one flexible element and the chassis holder is made possible via the relative movement.
