Measuring device and sensor for contactlessly measuring tire forces
First Claim
1. Method of contactlessly detecting the change in position of a measuring point on or in a tire on the basis of a force acting on the tire, comprising the steps of:
- rotating a sensor and a measuring point with the rotation of a tire rim arranging a source of radiation to irradiate from or to irradiate upon said measuring point, using the sensor to detect the irradiation irradiating from or upon said measuring point such that said sensor detects the change in position of the measuring point in a longitudinal or transverse direction in relation to a running surface of the tire.

Abstract
The present invention relates to a sensor as well as a measuring device with a sensor of this type for contactlessly detecting the change in position of a measuring point on or in a tire on the basis of a force acting on the tire of a wheel, in particular during driving, wherein the sensor is fixed in a stationary position in relation to the rim of the wheel. So as to be able to measure, in a simple manner, the transversal and longitudinal forces acting on the tire during driving, the sensor detects the change in position of the measuring point in the longitudinal or transverse direction (y,x) in relation to the running surface of the tire.

9. A measuring device for measuring the change in position of a measuring point on or in a tire on the basis of a force acting on the tire, comprising:
-
a sensor attached to at least one of the tire, a wheel of the tire or, a valve of the tire, wherein said sensor rotates with said tire rim, a reference point associated with at least one of the tire, the tire wheel, or the tire valve, wherein said reference point rotates with said tire rim, a radiating source for irradiating said measuring point wherein said sensor senses the radiation irradiated upon said measuring point or radiation irradiated from said measuring point such that said sensor detects a change in position of the measuring point in a longitudinal or transverse direction in relation to a running surface of said tire. a reference point associate with at least one of the tire, the tire wheel, or the tire volve, wherein said reference point rotates with said tire rim, a radiating source for irradiating said measuring paint wherein said sensor senses the radiation irradiate upon said measuring point or radiation irradiated from said measuring point such that said sensor detects a change in position of the measuring point in a longitudinal or transverse direction in relation to a running surface of said tire. - View Dependent Claims (10, 11, 12)
