Abstract
A vehicle steering apparatus. The durability of a sensor rotor to heat and abrasion is improved. The flatness of the sensor rotor is prevented from being lowered during calking for coupling of the sensor rotor to a steering shaft so that steering torque of a driver can be more accurately detected. A fabrication process is simplified, and fabrication costs are reduced.
Claims12
A vehicle steering apparatus comprising:
- a first shaft to which one which one end of a torsion bar and a torque sensor are coupled;
- a second shaft to which the other end of the torsion bar is coupled, the second shaft having a recess in an outer circumferential surface of one end portion thereof;
- and
- a sensor rotor comprising an annular body coupled to the outer circumferential surface of the one end portion of the second shaft and having a stepped portion being provided on an inner circumferential surface of the annular body to be open in one axial direction, and blades protruding from outer circumferential portions of the annular body to face the torque sensor, wherein the annular body of the sensor rotor has one or more protrusions protruding from the stepped portion provided on the inner circumferential surface of the annular body.
