TH30859B - A device for monitoring the stress that occurs on the tire. - Google Patents

Abstract

DC60 tires, which during operation experience one or more severe stresses, leading to a noticeable decrease in their service life under normal conditions. in order to be able to find that Have the tires passed such harsh conditions? Tires are provided with a monitoring device consisting of at least one path which is sensitive to a given stress. and capable to remember details in such a way that corresponds to the stress that the component is subjected to at least within the specified time or the specified number of cycles. Tires which during operation experience one or more severe stresses, leading to a noticeable decrease in their service life under normal conditions. in order to be able to find that Have the tires passed such harsh conditions? Tires are provided with a monitoring device consisting of at least one device that is sensitive to a given stress. and capable To memorize details in a way that corresponds to the stresses that the component undergoes at least within a given time or a given number of cycles.

Claims (7)

1. A device for monitoring the condition of damage to the reinforced structure. Of the tires used on the vehicle The tire consists of internal and external walls. Exert tire pressure Act on the interior walls and the structure being monitored through At least one or more cycles of variable mechanical stress, at least in the thinnest place, the device for monitoring damage to such structures, combined with a flexible carrier on one side. Its design is fixed to one wall of the tire and is close to the structure being guarded at And the way on the support Such a path is sensitive to Fatigue bend between the minimum value of the bend and the maximum value of the bend radius. Is a predetermined number of cycles And have the ability to permanently remember and display information Is associated with the damage of the monitored structure that has undergone a number of severe bends The cycle is at least as far as required. Which information that is permanently remembered Can be checked visually by the operator Or even automatically Which may or may not remove the tire 2. The monitoring device according to claim 1, with its unique characteristics: With at least the means Two of them that are extremely sensitive to bends. They are calibrated differently so that each one can be permanently recognized. One piece of information, depending on the reinforcement being monitored, which has undergone a predetermined bend stress between the maximum radius of curvature R max and the minimum radius of curvature. Rmin is the predetermined number of cycles. To get accurate indicators of Actual stress to the tire being used under severe bend conditions. 3. The monitoring device according to claim 2, characterized by the support fixed on the wall. Inside of the side of the car tire And the supports are made from at least a rubber material, which was chosen from the Diene family. Which are susceptible to fatigue stress in severe bending 4. The monitoring device according to claim 2, characterized by the fact that the support is fixed to Interior wall of one side of the tire And includes at least one piece of wire resting in a direction which can be marked on the support. Such parts have Persistent sensitivity to and has the ability to remember. Intense cyclical bend stress that appears as visible damage after a predetermined minimum cycle count. 5. Monitoring equipment according to claim 1, with its unique characteristics: Each piece of information that is Remember, the device can be read by radioscopy. Or radiography Radioscopy equipment Or radiography 6. Monitoring devices for providing an indication of the extent of the damage that Part of the tire's area is obtained due to the repeated act of vengeance, the monitoring device consists of a bent support intended to be attached to one wall of the tire. Cars at the said area And the bendable trajectory mounted on the said support. To provide an indication of the extent of the damage The materials of the bendable indicator path are designed to Fracture after repeated extreme bends, so that its fracture is an indication of the extent of Damage to that area of the tire 7. Tires according to claim 6, with a number of bendable indicating paths mounted on the supports, the indications were cut to cause fractures. To indicate the scope of Different damaged
