Torque sensor for vehicle

摘要

A torque sensor for automobiles capable of maintaining initial fabricated positions of components in a housing even though being subjected to thermal expansion or external shock is disclosed. Retaining elements (80) made of resilient material having excellent damping capability are interposed between an inner surface of a housing (20) and each of detection coil assemblies (30,40) by molding process to enable the components received in the housing to be securely held. Though being subjected to external vibration or shock, the external effect can be absorbed by damping effect of the retaining elements (80). Though the components in the housing thermally expand due to temperature variation, the retaining elements (80) are elastically deformed to accommodate volume increase by the thermal expansion. Since fabricated positions of the components can be securely maintained without axial and radial displacement, it is possible to precisely detect torque acting on a torsion bar (12). <IMAGE>
