Steering sensor assembly
The present document relates to a steering sensor assembly comprising an axle housing and a kingpin rotatably mounted on the axle housing, wherein the kingpin features a through hole extending through the kingpin. The steering sensor assembly further comprises a mounting member connected to the axle housing and at least partially disposed in the through hole extending through the kingpin, and a steering sensor comprising a first sensor portion coupled to the kingpin and a second sensor portion coupled to the mounting member.
1. Steering sensor assembly, comprising:
an axle housing,
a kingpin rotatably mounted on the axle housing, the kingpin featuring a through hole extending through the kingpin,
a mounting member connected to the axle housing and at least partially disposed in the through hole extending through the kingpin, and
a steering sensor comprising a first sensor portion coupled to the kingpin and a second sensor portion coupled to the mounting member, wherein the second sensor portion is coupled to the mounting member via an elastic member, and wherein the elastic member is received in an indentation formed at a second end of the mounting member in a form-fit.
2. The steering sensor assembly of claim 1 , wherein a first end of the mounting member is received in an indentation formed in the axle housing in a form-fit so that the mounting member is rotationally fixed to the axle housing with respect to a rotation axis of the kingpin and/or of the steering sensor.
3. The steering sensor assembly of claim 2 , wherein the indentation formed in the axle housing, the through hole extending through the kingpin, and the mounting member are shaped such that when the kingpin is rotatably mounted on the axle housing and the mounting member is at least partially disposed in the through hole extending through the kingpin, there is only exactly one relative angular orientation between the axle housing and the mounting member which allows the first end of the mounting member to be received in the indentation formed in the axle housing.
4. The steering sensor assembly of claim 2 , wherein the indentation formed in the axle housing features no rotational symmetry with respect to the rotation axis of the kingpin and/or of the steering sensor.
5. The steering sensor assembly of claim 2 , wherein the first end of the mounting member features one or more ground facets laterally offset from the rotation axis of the kingpin and/or of the steering sensor.
6. The steering sensor assembly of claim 2 , wherein the through hole extending through the kingpin comprises a cylindrical or conical section and the mounting member comprises a portion which is received in the cylindrical or conical section of the through hole extending through the kingpin in a form-fit.
7. The steering sensor assembly of claim 1 , further comprising a sealing member disposed in between the mounting member and the kingpin, the sealing member sealing the steering sensor from at least a section of the through hole extending through the kingpin.
8. The steering sensor assembly of claim 7 , wherein the sealing member comprises an annular sealing member received in an annular indentation formed in a surface of the mounting member.
9. The steering sensor assembly of claim 1 , wherein the elastic member comprises or is made of an elastomer.
10. The steering sensor assembly of claim 1 , wherein the second sensor portion is received in a recess formed in the elastic member in a form-fit so that the second sensor portion is rotationally fixed to the elastic member with respect to a rotation axis of the kingpin and/or of the steering sensor.
11. The steering sensor assembly of claim 1 , further comprising a connection member at least partially received in a through hole extending through the mounting member, the connection member having a male threaded portion engaged with a female threaded portion formed in the axle housing, the connection member fixing the mounting member to the axle housing.
12. The steering sensor assembly of claim 11 , wherein the connection member comprises an increased diameter portion and wherein a portion of the mounting member enclosing the through hole extending through the mounting member forms a shoulder portion which forms a seat portion for the increased diameter portion of the connection member.
13. The steering sensor assembly of claim 1 , further comprising a steering knuckle, wherein the kingpin is fixed to the steering knuckle.
14. A vehicle, comprising:
one or more wheels; and
a steering sensor assembly, comprising:
an axle housing, the axle housing configured to be stationary relative to the vehicle,
a kingpin rotatably mounted on the axle housing, the kingpin featuring a through hole extending through the kingpin,
a mounting member connected to the axle housing at a first end of the mounting member and at least partially disposed in the through hole extending through the kingpin, the mounting member configured to remain stationary relative to the axle housing, and
a steering sensor comprising a first sensor portion coupled to the kingpin and a second sensor portion coupled to a second end of the mounting member via an elastic member disposed in the through hole, the first sensor portion configured to rotate relative to the second sensor portion.
15. The vehicle of claim 14 , further comprising a steering knuckle coupled to the kingpin and a wheel hub coupled to the steering knuckle.
16. The vehicle of claim 14 , wherein the steering sensor is configured to generate a signal that changes based on an orientation of the second sensor portion relative to the first sensor portion.
17. The vehicle of claim 14 , wherein the second sensor portion is received in a recess formed in the elastic member in a form-fit so that the second sensor portion is rotationally fixed to the elastic member with respect to a rotation axis of the kingpin and/or of the steering sensor.
18. A steering sensor assembly, comprising:
an axle housing,
a kingpin rotatably mounted on the axle housing, the kingpin featuring a through hole extending through the kingpin,
a mounting member connected to the axle housing and at least partially disposed in the through hole extending through the kingpin, and
a steering sensor comprising a first sensor portion coupled to the kingpin and a second sensor portion coupled to the mounting member, wherein a first end of the mounting member is received in an indentation formed in the axle housing in a form-fit so that the mounting member is rotationally fixed to the axle housing with respect to a rotation axis of the kingpin and/or of the steering sensor, and wherein the indentation formed in the axle housing, the through hole extending through the kingpin, and the mounting member are shaped such that when the kingpin is rotatably mounted on the axle housing and the mounting member is at least partially disposed in the through hole extending through the kingpin, there is only exactly one relative angular orientation between the axle housing and the mounting member which allows the first end of the mounting member to be received in the indentation formed in the axle housing.
