Abstract
Official abstract text for this publication.
A system is used with a pneumatic tire mounted on a wheel rim to keep the pneumatic tire from becoming underinflated. The first system includes a plurality of pumps attached circumferentially to the wheel rim, each pump having pump parameters, and a control valve for controlling inlet air into a tire cavity of the pneumatic tire. The control valve has valve parameters. The system predicts system performance under various configurations and conditions through use of the pump parameters and the valve parameters.
First claim
Opening claim text (preview).
What is claimed: 1. A system for use with a pneumatic tire mounted on a wheel rim to keep the pneumatic tire from becoming underinflated, the system comprising: a plurality of pumps attached circumferentially to the wheel rim, each pump having pump parameters, each pump including one piston; a primary check valve disposed adjacent each pump; and a control valve for controlling inlet air into a tire cavity of the pneumatic tire, the control valve having valve parameters, the system predicting system performance under various configurations and conditions through use of the pump parameters and the valve parameters, each pump including one piston placed between two chambers connected by a narrow passage having a secondary check valve. 2. The system as set forth in claim 1 wherein the plurality of pumps and the control valve define a multi-chamber pump configuration. 3. The system as set forth in claim 1 wherein the plurality of pumps define a force control system with a maximum pumping capability determined by the one piston of each pump moving a maximum distance within each pump. 4. The system as set forth in claim 1 wherein each pump includes a first diaphragm limiting motion of the one piston in a first direction and a second diaphragm limiting motion of the piston in a second opposite direction. 5. The system as set forth in claim 1 wherein the pump parameters include a piston mass parameter, a first piston travel parameter, and a second piston travel parameter. 6. A system for modeling a pneumatic tire mounted on a wheel rim and a pumping mechanism mounted on the wheel rim to keep the pneumatic tire from becoming underinflated, the system comprising: a plurality of pumps attached circumferentially to the wheel rim, each pump having pump parameters; and a control valve for controlling inlet air into a tire cavity of the pneumatic tire, the control valve having valve parameters, the system predicting system performance under various configurations and conditions through use of the pump parameters and the valve parameters, each pump including a first diaphragm limiting motion of a piston in a first direction and a second diaphragm limiting motion of the piston in a second opposite direction. 7. The system as set forth in claim 6 wherein the plurality of pumps and the control valve define a multi-chamber pump configuration. 8. The system as set forth in claim 6 wherein each pump includes one piston placed between two chambers. 9. The system as set forth in claim 8 wherein the two chambers are connected by a narrow passage having a check valve. 10. The system as set forth in claim 6 wherein the plurality of pumps define a force control system with a maximum pumping capability determined by a piston of each pump moving a maximum distance within each pump.
