A hydropneumatic suspension system for vehicles, at least consisting of an axle suspension (10) and a cabin suspension (12), which for supplying them with pressurized fluid, can be connected to a pressure supply source, is characterized in that both the axle suspension (10) and the cabin suspension (12) can be actuated jointly by means of an control device (14), and in that, by means of a priority detection system (16) involving a sensor device (18) for the respective suspension (10, 12), the supply with pressurized fluid of the one suspension (10, 12) takes precedence depending on demand over the other suspension (12, 10).

A cab mounting including a chassis holder and a cab holder. The chassis holder includes a chassis plate having a central region, designed to be fastened to a chassis of a vehicle, a lower end region, designed to fasten a suspension element, and an upper end region having an opening, designed for connecting to an upper bearing plate. 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 in order to be held movably in the opening of the chassis plate, such that the chassis holder and the cab holder are movable relative to each other. The chassis holder is formed in one piece such that impacting dirt is scraped off.

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.

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.

A noise reducing system for a tracked vehicle, the tracked vehicle comprising a cab and at least one track that extends along a direction of travel of the vehicle and comprises at least a plurality of bars, such as metal bars, transverse to the direction of travel. The noise reducing system comprising a control unit and an acoustic wave emitter connected to the control unit for being controlled by the control unit, the noise reducing system comprising an acoustic input and being configured to emit an acoustic equalization wave, phase shifted with respect to the noise and determined on the basis of the acoustic input, to reduce the noise, in particular the noise generated by the tracks.

An air suspension assembly comprises a top and a bottom disposed on a center axis and spaced apart from one another. A bellows of an elastomeric material extends between a first end secured to the top and a second end secured to the bottom defining a chamber. The chamber extends between the top, the bottom, and the bellows for containing pressurized air, whereby a pressure of the pressurized air is controlled based on a force applied. The bellows has an interior surface and an exterior surface and including a plurality of convolutes extending between the first end and the second end. Each convolute of the plurality of convolutes includes a pair of outer lobes and an inner lobe with each outer lobe of the pair of outer lobes having an outer lobe thickness extending between the interior surface and the exterior surface of the bellows.

A freight vehicle has a frame defining a support surface for the goods to be transported, a plurality of rubberized wheel assemblies with suspensions, the height of which can be adjusted to shift the support surface between a lowered loading position and a raised transport position, and a driver's cab arranged beneath said support surface; the cab being coupled to, and overhanging, the frame by means of an articulated quadrilateral transmission unit and being shifted by pneumatic actuators configured to vertically move the whole cab in relation to the support surface between two extreme end positions, one approaching the support surface and one spaced apart from said support surface, and to arrange the cab in a cushioned intermediate position for the transport of the goods.

A noise reducing system for a tracked vehicle, the tracked vehicle comprising a cab and at least one track that extends along a direction of travel of the vehicle and comprises at least a plurality of bars, such as metal bars, transverse to the direction of travel. The noise reducing system comprising a control unit and an acoustic wave emitter connected to the control unit for being controlled by the control unit, the noise reducing system comprising an acoustic input and being configured to emit an acoustic equalization wave, phase shifted with respect to the noise and determined on the basis of the acoustic input, to reduce the noise, in particular the noise generated by the tracks.
