Sensor device for speed measurement on a wheel of a vehicle
First Claim
1. A sensor device for speed measurement on a wheel of a vehicle, the sensor device comprising:
- a sensor carrier extending longitudinally to define an axial direction, the sensor carrier including an outer surface that defines a plurality of longitudinal grooves recessed therein and extending in the axial direction;
a sensor integrated in the sensor carrier to sense the rotation of an exciter wheel co-rotating with the wheel; and
a clamping mechanism integrated in the sensor carrier, the clamping mechanism including a plurality of clamping strips each having an elongated member extending in the axial direction of the sensor carrier within a respective one of the plurality of longitudinal grooves, each of the plurality of clamping strips further including a spring element extending outwardly from the elongated member of the clamping strip in a radial direction, beyond the outer surface of the sensor carrier such that each spring element protrudes from a respective one of the plurality of grooves to engage an inner surface of a holding opening opposite of the sensor carrier outer surface in a region of the wheel, by which the sensor carrier is (i) axially displaceably clampable in the holding opening in a region of the wheel and (ii) clampable in any orientation in respect to rotations about a longitudinal axis of the sensor carrier.

Abstract
A sensor device for speed measurement on a wheel of a vehicle includes a sensor carrier with an integrated sensor to sense the rotation of a pole wheel that rotates along with the wheel. The sensor device has a clamping mechanism integrated into the sensor carrier by which the sensor carrier can be displaceably clamped into a holding opening in the region of the wheel and/or in any orientation with respect to rotations about the longitudinal axis of the sensor carrier. The sensor arrangement can be mounted with less effort and more cost-efficiently than with the current international standard of combining a clamping bush and subsequently mounted rod sensor. Spring-loaded clamps can be fastened as terminal blocks in longitudinal grooves in the sensor, and the spring-loaded elements thereof can protrude over the circumference of the sensor prior to mounting.
