Steering column with stationary hub
First Claim
Patent Images
1. A steering column assembly comprising:
- a column shaft rotatable about an axis and configured to couple to a steering wheel rim;
a hub support configured to be non-rotatably coupled to a first stationary support structure of a vehicle;
a stationary hub coupled to the hub support, the steering wheel rim rotatable relative to the stationary hub;
a drive mechanism operatively coupled to the column shaft, the drive mechanism transmitting torque between the column shaft and an intermediate shaft; and
a column jacket coupled to a second stationary support structure of the vehicle, the hub support, the column shaft and the column jacket concentrically and coaxially oriented relative to each other, the column shaft radially outward of the hub support, the column jacket radially outward of the column shaft.

Abstract
A steering column assembly is provided. The assembly includes a column shaft rotatable about an axis and configured to couple to a steering wheel rim and a hub support configured to be non-rotatably coupled to a support structure of the vehicle. A stationary hub is coupled to the hub support, the steering wheel rim being rotatable relative to the stationary hub.

14. A method of assembling a steering column assembly comprising:
-
providing a column shaft rotatable about an axis; coupling a steering wheel rim to the column shaft; non-rotatably coupling a hub support to a first stationary support structure of the vehicle, the column shaft located radially outward of the hub support and concentric about the hub support; coupling a stationary hub to the hub support, the steering wheel rim rotatable relative to the stationary hub; coupling a column jacket to a second stationary support structure of the vehicle, the column jacket concentric about and coaxial with the column shaft; and coupling a pulley assembly of a drive mechanism to the column shaft and to an additional shaft to transmit torque between the column shaft and the additional shaft.
