Force sensor for a motor vehicle for determination of an axially directed force, e.g. the force applied to a braking caliper, has a sensor ring that can be placed between force applying and receiving components without clamping

摘要

Force sensor comprises a measurement ring (2) with strain gauge pairs (7). Input forces are applied to the ring by projections (3-5) with corresponding reaction forces (FR) applied to the forward side of the ring is support areas (6) that are centered between the projections. The strain gauge pairs are positioned in resultant bending sections between projections and support areas.
