  • Method for recognition of a pressure loss in motor vehicle tires
    Patent number: 8180523
    Abstract: Disclosed is a method for detection of a pressure loss in motor vehicle tires, which detects pressure loss on at least one vehicle tire based on several parameters, which are calculated from the rolling circumference of the tires. To this end, currently calculated parameters are compared with learnt values of the parameters.
    Type: Grant
    Filed: July 6, 2005
    Date of Patent: May 15, 2012

  • Method for determining internal pressure of a vehicle tire
    Patent number: 7203612
    Abstract: Disclosed are different processes for the determination of the internal pressure, particularly of the minimum pressure of the tire of a motor vehicle during driving operation, through an analysis of the characteristic vibration behavior of the wheel, whereby the standardized amplitude is determined from the vibration spectrum determined and the resonance frequency is observed.

  • Filler ring for a vehicle wheel and tire assembly
    Patent number: 4791972
    Abstract: A filler ring, made of rubber or synthetic material, for a vehicle wheel and pneumatic tire assembly where the beads of the tire are mounted on the radially inner periphery of a wheel rim next to essentially radially inwardly extending rim flanges. The filler ring covers a space located axially inwardly of a rim flange. The filler ring includes at least two planes of circumferential hollow chambers, with the planes of hollow chambers being superimposed on one another in a radial direction, and with at least two hollow chambers, which are successively arranged in an axial direction, being provided in each of the planes of such hollow chambers.
