摘要:
A monitoring device and patch assembly includes a patch that removably and re-attachably holds the monitoring device. The patch is adapted to connect the monitoring device to a pneumatic tire when the monitoring device is held by the patch. The patch is configured to hold a monitoring device having a rounded outer surface. The patch holds the rounded monitoring device by having a resilient tube with an outlet having a diameter smaller than the diameter of the monitoring device. The monitoring device of the invention includes a feature that allows it to be removed from the patch.

A tire monitor assembly includes a rubber ply having a first side affixable to an interior surface of a tire. A pedestal extends from a second side of the rubber ply, wherein the pedestal has a top surface and at least one sidewall. The pedestal has a groove disposed in the at least one sidewall that extends along a perimeter of the pedestal, wherein the pedestal has a cavity disposed in the top surface, extending towards the rubber ply. The assembly further includes a tire monitoring device and a fastener connected to the tire monitoring device and further connected to the pedestal such that the fastener is disposed in at least one of the cavity and the groove.
摘要:
A sensor system for obtaining data from an air spring having elastomeric body with a plurality of wireless sensors embedded therein. The sensor length-scales range from nano- to micro-scale devices that are small enough to avoid becoming occlusions within the elastomeric body. The air spring may include a spring wall having an internally reinforced elastomeric body portion with the sensors embedded within. The air spring may include a spring wall having an unreinforced elastomeric body portion with the sensors embedded within. The sensors may be configured to provide data related to one or more of temperature, pressure, sidewall flex, stress, strain and other parameters. The sensors may be LCD sensors, and/or conductive polymer sensors, and/or bio-polymer sensors and/or polymer diodes suitable for sensing data during the operation of the air spring.

A sensor system for obtaining data from an elastomeric article includes at least one wireless sensor. The sensor length-scales range from nano- to micro-scale devices that are small enough to avoid becoming occlusions within the article. The article may include sensors embedded within one of the materials of the article, a layer of sensors built into the article, and a string of sensors disposed within a component or embedded within a component of the article. The sensors may be configured to provide data related to one or more of temperature, pressure, sidewall flex, stress, strain and other parameters. The sensors may be LCD sensors, and/or conductive polymer sensors, and/or bio-polymer sensors and/or polymer diodes suitable for sensing data during the operation of the tire. A power circuit using energy generated by the tire may provide power to the sensors.
摘要:
An improved method and apparatus permits the insertion and removal of an electronic monitoring device from a tire, while securing the electronic monitoring device to the tire so that stress, strain, impact, cyclic fatigue and vibration are minimized. After a rubber patch is vulcanized, the patch is permanently assembled to the innerliner of a vulcanized tire by affixing it to the tire innerliner. An electronic monitoring device, after having been encapsulated in a suitable rigid potting material to form a rigid tag, is fitted with a power source to form a tag assembly in a shape which allows for insertion into a cavity in the patch. The tag is carefully inserted into the cavity housing. The tag assembly is locked into place within the cavity using a suitable removable locking device.

摘要:
A method for monitoring various engineering conditions of a pneumatic tire such a temperature, pressure, tire rotation and other operating conditions of the tire. A tire tag is mounted on the interior of the tire within the pressurizable cavity and contains the stored data and sensors for detecting certain conditions within the cavity. A separate transponding device is mounted on the tire rim. The tire tag contains a battery, an antenna and stored data pertaining to the tire. The transponding device uses electronic circuitry which collects data from the tire tag. The tire tag is actuated by transmitted radio frequency waves from the transponding device, which data is retransmitted by the transponding device to the remote location by an antenna which extends from the transponding device through the rim to a location externally of the tire.
摘要:
A system and apparatus for accurately delivering rubberized sheets from a supply roll of stock material containing an intervening liner to an assembly station for subsequent assembling into an air spring or similar article of manufacture by eliminating the heretofore formation of a "free loop" therein. The supply roll and a liner take-up reel are rotatably mounted on a carriage transversely movable with respect to the longitudinal motion of the stock material. A hugger device has a plurality of timing belts which frictionally engage the liner at the take-up reel and winds the liner onto the reel at a constant linear speed regardless of the diameter of the reel and collected liner to move the rubberized sheet at a controlled rate toward the assembly station. The motion profile of the timing belts is controlled by a servo drive motor and the belts engage an arcuate portion of the circumference of the take-up reel to provide positive frictional drive engagement therewith. The carriage is moved along a pair of tracks by a ballscrew mechanism for bringing the cartridges of stock material and take-up reel into position with the timing belts and assembly station. An optical edge detection device and encoder, in conjunction with a motion controller, accurately control and regulate the system.

A multi layered tire former bladder and a method for making the bladder is described. The multi layered bladder includes a elastomeric bladder having an outer surface and an inner surface; a release coating on the outer surface of the bladder; and at least two fabric reinforcing plies which include a first outer ply embedded in the bladder below the outer surface and an inner surface fabric ply at the inner surface of the bladder. In the method of making the bladder an air dried release coating is applied to the outer elastomeric surface of the bladder.
摘要:
A monitoring device and patch combination used to monitor the conditions of a pneumatic tire having an innerliner includes a monitoring device and patch. The monitoring device includes a first connection element that is connected to the monitoring device. The patch includes an antenna that is connected to a second connection element. In one embodiment of the invention, the first connection element is in the form of a socket while the second connection element is in the form of a plug. The connection elements allow the monitoring device and patch to be separately fabricated and the direct physical connection between the antenna and the monitoring device to be formed when the combination is connected to the innerliner of the tire. In another embodiment, a plug extends from the bottom of an encapsulated monitoring device and is aligned with a socket on the patch. The connection between the plug and the socket occurs automatically when the encapsulated monitoring device is aligned with and connected to the patch.
