Steering device anti-rotation assembly
View Patent ↗A steering column assembly includes a steering shaft operatively coupled to a steering device, the steering shaft and the steering device having corresponding rotation with each other. Also included is an anti-rotation assembly selectively engaged with a surface of the steering shaft to maintain the steering shaft and the steering device in a stationary condition when the steering shaft is rotationally decoupled from road wheels operatively coupled to the steering shaft.
1. A steering column assembly comprising:
a steering shaft operatively coupled to a steering device, the steering shaft and the steering device having corresponding rotation with each other; and
an anti-rotation assembly selectively and frictionally engaged with an outer surface of the steering shaft to maintain the steering shaft and the steering device in a stationary condition when the steering shaft is rotationally decoupled from road wheels operatively coupled to the steering shaft, wherein the anti-rotation assembly comprises a friction shoe having a contact engagement surface selectively in contact with a contact surface region of an outer circumference of the steering shaft.
2. The steering column assembly of claim 1 , wherein a curvature of the contact engagement surface corresponds to a curvature of the contact surface region.
3. The steering column assembly of claim 1 , wherein the anti-rotation assembly further comprises an actuator, the actuator selectively moving the friction shoe into and out of contact with the steering shaft.
4. The steering column assembly of claim 3 , wherein the actuator is at least one of an electric actuator, a hydraulic actuator, and a pneumatic actuator.
5. The steering column assembly of claim 4 , wherein the actuator is in operative communication with a controller that is part of an advanced driving assist steering (ADAS) system.
6. The steering column assembly of claim 3 , wherein the actuator is connected to the friction shoe with a pin that extends and retracts to selectively place the friction shoe in contact with the steering shaft.
7. The steering column assembly of claim 1 , wherein the steering column assembly is part of a steer-by-wire steering system.
8. A steering column assembly comprising:
a steering shaft operatively coupled to a steering device, the steering shaft and the steering device having corresponding rotation with each other, the steering device translatable to a retracted position in an autonomous driving mode, the retracted position placing the steering device proximate an instrument panel; and
an anti-rotation assembly selectively and frictionally engaged with an outer surface of the steering shaft to maintain the steering shaft and the steering device in a stationary condition when the steering device is in the retracted position, wherein the anti-rotation assembly comprises a friction shoe having a contact engagement surface selectively in contact with a contact surface region of an outer circumference of the steering shaft.
