Embodiment Construction

[0025] figure 1 An embodiment of an air storage system 1 according to the invention is shown comprising wheels on the axle 35 of a truck (not shown) with tires 100 for storing a container of air; and control means 200 controlling the input and output of air from the tire 100 to the suspension system based on information relating to at least the air pressure of said at least one tire. The air storage system can be used when the tire is idle, ie not used for driving, and when the wheel / tyre is used for driving.

[0026]The air control device 200 may include a processor 210 that may communicate with an air pressure sensor 220 for measuring the pressure of the tire 100 that transmits an air pressure data signal representative of the measured tire air pressure to the The processor 210. Preferably, the processor may receive data signals indicative of other information, for example, information about when the tire 100 is idle provided by a rotation sensor (not shown) or a speedomet...

Abstract

An air storage system (1) for an air suspension system (2) in a large vehicle (3), comprising at least one tire (100), preferably at least one set of tires, provided on an axle (35) of the vehicle (3); wherein the system comprises air control means (200) adapted for selectively controlling the input and output of air from said at least one tire (100) to said air suspension system (2) based on data signals at least representing air pressure in said at least one tire (100) at least when said tire is idle, i.e. not engaged in driving.

Description

technical field [0001] The present invention relates to an air storage system for an air suspension system in a heavy vehicle. Background technique [0002] Large or heavy vehicles, such as trucks and buses, are often equipped with air suspension systems that use compressed air from an auxiliary air storage tank provided by an air compressor within the vehicle. Typically, these suspension systems are provided on the front and / or rear axles to absorb fluctuations in the road surface to provide a smooth ride, and to reduce loads on the chassis and tires. Air suspension systems include air-filled bellows in place of or in addition to spring members, such as leaf springs. As the load increases, bladder air pressure increases to compensate, raising the chassis back to its preset height. Thus, for example, a heavy vehicle may use automatic height control to maintain its height when loading or unloading, or it may lower or raise its height manually by using a control box. [000...
