TENSION MEASURING ASSEMBLY FOR ELECTRICAL PARKING BRAKE

摘要

PURPOSE: A tension measuring assembly for an electronic parking brake is provided to prevent a deviation between sensing values for measuring tension since physical properties of a part does not change in a manufacturing process. CONSTITUTION: A tension measuring assembly for an electronic parking brake comprises a cable connecting rod(110), a spring(120), a moving member(130), a magnetic-field radiating unit(140) and a reluctance sensor(150). The cable connecting rod moves in a length direction according to the tension of a parking cable, which is coupled to one end of the cable connecting rod. The spring applies elastic restoring force to the cable connecting rod in proportion to the moving distance of the cable connecting rod. The moving member is coupled to the other end of the cable connecting rod and moves together. A tapered metallic unit is installed on one side of the moving member.
