Torque sensor apparatus
A torque sensor apparatus includes a torque sensor; a sensor accommodation unit disposed at one side of a rack housing and having therein a space in which the torque sensor is disposed; a sensor cover screw-coupled to the sensor accommodation unit and configured to cover the space; and a wire harness coupled to the sensor cover and electrically connected to the sensor.
1. A torque sensor apparatus comprising:
a torque sensor;
a sensor accommodation unit disposed at one side of a rack housing and having therein a space in which the torque sensor is disposed;
a sensor cover screw-coupled to the sensor accommodation unit and configured to cover the space; and
a wire harness coupled to the sensor cover and electrically connected to the sensors,
wherein
a through-hole is formed in the sensor cover through which a connector disposed at the tip portion of the wire harness passes,
the connector of the wire harness passes through the through-hole of the sensor cover and is coupled to the torque sensor,
the wire harness is coupled to the sensor cover by means of a wire cover, and
the wire cover includes a first fixing portion fixedly coupled to the sensor cover by means of a coupling member and a second fixing portion rotatably connected to the first fixing portion.
2. The torque sensor apparatus of claim 1 , wherein the sensor accommodation unit comprises:
a seating portion on which the torque sensor is provided; and
a wall portion protruding along a periphery of the seating portion and configured to define the space, and
wherein a first screw thread is formed on the wall portion and screw-coupled to the sensor cover.
3. The torque sensor apparatus of claim 2 , wherein the first screw thread is formed on an inner peripheral surface of the wall portion.
4. The torque sensor apparatus of claim 2 , wherein the sensor cover has a dome shape and comprises a coupling portion having a second screw thread screw-coupled to the first screw thread.
5. The torque sensor apparatus of claim 4 , wherein the second screw thread is formed on an outer peripheral surface of the coupling portion.
6. The torque sensor apparatus of claim 4 , wherein the sensor cover comprises a flange portion disposed to overlap an end surface of the wall portion in an upward/downward direction in a state in which the coupling portion is screw-coupled to the wall portion.
7. The torque sensor apparatus of claim 6 , comprising:
a sealing member disposed between an upper-end surface of the wall portion and the flange portion.
8. The torque sensor apparatus of claim 2 , wherein the seating portion has a pinion hole, and a pinion shaft penetrates the pinion hole.
9. The torque sensor apparatus of claim 1 , wherein the through-hole is formed coaxially with a rotation axis about which the sensor cover rotates relative to the sensor accommodation unit.
