The vehicle comprises a gas line which is connected to all of the wheel tires simultaneously and is coupled to a system for inflating the tires. A suspension comprises a wheel springing system connected to the wheel tires, a pneumatic drive and a system for inflating the tires, wherein the wheel springing system is configured in the form of an gas line formed from the cavities of the pipes from which a frame is welded, or is configured outside the frame, forming a closed loop that is connected to each of the tires by means of pipes with closure members, and wherein the pneumatic drive and the system for inflating the tires are constituted by an engine exhaust system which is provided with a baffle and is coupled to the air line by means of a pipe with a closure member.

Disclosed herein are devices and systems for continuous control of tire pressure. In one aspect, a device for continuously controlling tire pressure includes a bracket, a fixed non-rotating member fixedly attached to the bracket, and a non-fixed rotating member rotatably attached thereto. The fixed non-rotating member has at least one first seal surface, the at least one seal surface configured to be in fluid communication with a compressed air source. The non-fixed rotating member has at least one second seal surface, wherein an air chamber defined within a volume between interacting the at least one first seal surface and the at least one second seal surface causes fluid communication between an interior space of the tire and the compressed air source.

The invention relates to an assembly including a hydraulic apparatus having a rotor and a stator. The rotor is mounted so as to turn about a second rotation axis with respect to the stator and is secured to a device suitable for mounting a vehicle wheel. A pivot-pin element is intended to be mounted on an axle and is mounted so as to rotate about a first rotation axis with respect to the hydraulic apparatus. The stator is mounted so as to turn about the first rotation axis with respect to the axle. An air chamber is formed between the pivot-pin element and the hydraulic apparatus, the air chamber is connected to a distribution passage formed in the hydraulic apparatus. An axle passage is formed in the pivot-pin element so as to form a pneumatic passage between the pivot-pin element and the hydraulic apparatus.

A valve assembly for a tire pressure control system used to control tire pressure of a vehicle has a unitary body and one or more valves. The unitary body has attachment points for mounting the unitary body to a vehicle wheel end, one or more valve cavities formed in the unitary body, and a plurality of air passages formed in the unitary body. The plurality of air passages have an air supply passage that is connectable to an air supply and a tire supply chamber for connecting to a tire of the vehicle. The air supply passage and the tire supply chamber are connected to each of the one or more valve cavities. Each valve has a valve element mounted to the valve cavity, an air supply chamber in communication with the air supply passage, and a tire supply chamber in communication with the tire supply passage.

A valve assembly for a tire pressure management system includes a housing having a first perforation and a second perforation. The first perforation is selectively in fluid communication with the second perforation. A shuttle assembly is provided in the housing. A failsafe piston is connected to the shuttle assembly. A first biasing member applies a bias to the failsafe piston. A second biasing member applies a bias to the shuttle assembly. When a pressure differential between a pressure in the second perforation and a pressure in the first perforation is at or below a predetermined value, the bias applied by the first biasing member urges the failsafe piston toward the shuttle assembly to prevent fluid communication between the first perforation and the second perforation.

An air supply system for a work vehicle includes a compressor configured to compress a first supply of ambient air and to output a compressed air supply via a compressed air line, an air induction assembly configured to receive the compressed air supply from the compressed air line and to flow the compressed air supply through a body of the air induction assembly to create a low pressure region sufficient to draw in a second supply of ambient air, wherein the body is configured to combine the second supply of ambient air with the compressed air supply to generate a combination air supply, and a tire inflation system fluidly coupled to the air induction assembly and configured to selectively increase and decrease an air pressure within a tire of the work vehicle.
