Abstract
A load-based tire inflation system for a heavy-duty vehicle comprises at least one source of fluid pressure, suspension structure of the heavy-duty vehicle, a tire and wheel assembly and a system to control fluid pressure in the tire and wheel assembly. The suspension structure is located between a frame member and an axle and has a condition indicative of a weight of the heavy-duty vehicle. The tire and wheel assembly is operatively mounted to the axle and is in fluid communication with the source of fluid pressure. The control system controls fluid pressure in the tire and wheel assembly in response to the condition of the suspension structure.
Claims19
A load-based tire inflation system for a heavy-duty vehicle comprising:
- at least one source of fluid pressure;
- a suspension structure of the heavy-duty vehicle, the suspension structure having a condition indicative of a load of the heavy-duty vehicle;
- a tire and wheel assembly operatively mounted to an axle of the heavy-duty vehicle and in fluid communication with the at least one source of fluid pressure;
- and
- means for controlling fluid pressure in the tire and wheel assembly in response to the condition of the suspension structure, said controlling means providing fluid flow to and maintaining the tire and wheel assembly at a pre-selected fluid pressure in the absence of electrical power.
A load-based tire inflation system for a heavy-duty vehicle comprising:
- at least one source of fluid pressure;
- a suspension structure of the heavy-duty vehicle, the suspension structure having a condition indicative of a load of the heavy-duty vehicle;
- a tire and wheel assembly operatively mounted to an axle of the heavy-duty vehicle and in fluid communication with the at least one source of fluid pressure;
- and
- means for controlling fluid pressure in the tire and wheel assembly in response to the condition of the suspension structure, said means providing fluid flow to the tire and wheel assembly and being free of any electrically-powered components.
A load-based tire inflation system for a heavy-duty vehicle comprising:
- at least one source of fluid pressure;
- a suspension structure of the heavy-duty vehicle, the suspension structure having a condition indicative of a load of the heavy-duty vehicle;
- a tire and wheel assembly operatively mounted to an axle of the heavy-duty vehicle and in fluid communication with the at least one source of fluid pressure;
- and
- means for controlling fluid pressure in the tire and wheel assembly in response to the condition of the suspension structure, said means providing fluid flow to the tire and wheel assembly, said suspension structure being in fluid communication with only non-electronic components of the controlling means.
