Publication number: 20220065310Abstract: For controlling electromechanically actuatable brakes of servo type construction, it is necessary to detect the forces acting on the abutment of the brake shoes. The abutment is therefore formed from a massive material which deforms under load, wherein measurement devices are provided which detect this deformation. The shape of the abutment is selected in such a way that the abutment has measurement gaps, the size of which changes when the abutment is loaded. The size of the measurement gaps can be sensed by means of Hall sensors or AMR sensors, for example.Type: ApplicationFiled: December 17, 2019Publication date: March 3, 2022Applicant: Continental Teves AG & Co.
