Patent ID: 7364020

Claim:
A measuring device for an electromechanical brake (EMB) in a motor vehicle, wherein the brake comprises a brake shoe and a caliper, and an actuating element for introducing a force between the brake shoe and the caliper, the measuring device comprising: a force sensor ( 42 ) in the form of a closed ring which has in cross section a C-shaped profile with two parallel limbs ( 48 , 50 ) arranged spaced apart from one another; regions for introducing said force of the actuator into the ring, the regions being between the actuating element ( 18 ) for the brake shoe ( 14 ) and the caliper ( 16 ) of the brake, wherein the regions are situated at the free end of the limbs ( 48 , 50 ) on the outside thereof; and a strain gauge ( 62 ) that is arranged on the outside of the ring next to one of the force-introduction regions of the limbs ( 48 , 50 ), wherein the strain gauge ( 62 ) is arranged on one of the limbs along the circumference of the force sensor.
