摘要： A system (10) for measuring the dynamic orientation of the plane of a wheel (12) on a vehicle (14). The system (10) includes a test surface (16) which rotates with the wheel (12) and a orientation-determining device (18) which is unattached to the vehicle (14). The test surface (16) is positioned in a plane corresponding to the plane of the wheel (12) and the orientation-determining device (18) determines the orientation of the plane of the test surface (12) at a specific point of time while the vehicle is being driven. A processor (20) receives output signals from the orientation-determining device (18) and converts the output signals into data corresponding to the orientation of the wheel plane for the specific instant in time.

摘要： a method for indoor wear testing tires includes the steps of characterizing a vehicle and a wear test course and combining the characterized data to create input data for an indoor wear test machine. The input data allows the indoor wear test machine to accurately simulate an outdoor wear test course for the characterized vehicle. The method allows multiple wear test courses to be used with a single characterized vehicle and allows a single wear test course to be used with multiple characterized vehicles. The method allows tires to be wear tested in relatively short time periods in the controlled environment of the indoor laboratory. In addition, the method is relatively easy to set up and perform.

摘要： A powder dispensing/collection device for indoor testing of pneumatic tires includes a first outer housing (12) having an open end (24) facing a road wheel (94). First and second adjustable shrouds (28), (32) are disposed on an upper and lower portion of the outer housing respectfully. The shrouds are selectively moveable in a direction perpendicular to a width (w) of the outer housing. A second inner housing (48) is partially enclosed by the outer housing and has an open end (64) facing the road wheel which protrudes out from the outer housing a predetermined distance. At least one of the outer walls of the inner housing and the inner walls of the outer housing define a vacuum collection chamber (76). The inner housing is manually moveable within the outer housig so that the distance between the open end of the inner housing and the road wheel can be adjusted. A hose (78) extends through an aperture (80) in the inner housing and into the dispensing chamber. A spray nozzle (84) is connected to the free end of the hose. The position of the spray nozzle within the dispensing chamber is adjustable by manually moving the nozzle backward or forward within the inner housing. At least one vacuum duct (82a, 82b) is operatively connected to a rear wall (22) of the outer housing for transferring a vacuum force to the vacuum collection chamber.
