Title: TORQUE SENSOR HAVING A SEALING MEMBRANE
Abstract:
The invention relates to a torque sensor (1000; 1100) having a base body (1001; 1101), which extends in a radial direction (Y) of the base body from an annular inner flange (1003; 1103) with first force introduction points (1005; 1105) via a mechanically weakened sensor portion (1007; 1107), which is fitted with measuring sensors (10, 20) generating output signals, to an annular outer flange (1009; 1109) with second force introduction points (1011; 1111), wherein a rubber-elastic sealing membrane (1031; 1131), which is arranged axially between the outer flange (1009; 1109) and the inner flange (1003; 1103), covers the mechanically weakened sensor portion (1007; 1107) in a fluid-tight manner.
