Abstract
A steering column assembly for a motor vehicle having adjustable tilt including a tilt housing pivotally connected to a support housing on an upper end of a tubular column sleeve. Pivotal connection is accomplished through a pair of coaxially aligned fasteners extending along a horizontal tilt axis and positioned on opposite sides of a rotatable steering shaft carried inside the column sleeve. The fasteners are separately actionable to reversibly adjust their lengths and thereby create a tuned frictional engagement between the support housing and the tilt housing so that objectionable rattling noises in the column assembly can be attenuated.
Claims18
A steering column assembly for a motor vehicle having adjustable tilt, said assembly comprising:
- a generally tubular column sleeve having a support housing disposed on an upper end thereof,
- a steering shaft rotatably carried within said column sleeve about a longitudinal steering axis;
- a tilt housing pivotally connected to said support housing for articulating movement about a tilt axis generally perpendicular to said longitudinal steering axis;
- a pair of co-axially aligned fasteners extending along said tilt axis and interconnecting said tilt housing to said support housing on opposite sides of said steering shaft, said fasteners independently telescopically adjustable to establish a predetermined compression condition between said support housing and said tilt housing;
- each of said fasteners having a respective first end in pressing contact with said support housing and a second end in pressing contact with said tilt housing;
- and
- said fasteners being separately actionable to draw said respective first and second ends toward one another to establish a tuned frictional engagement between said support housing and said tilt housing whereby objectionable rattling noises in said column assembly can be attenuated through the deliberate and independent manipulation of said fasteners to the predetermined compression condition.
A method for attenuating objectionable rattling noises in a steering column assembly for a motor vehicle having adjustable tilt, said method comprising the steps of:
- providing a generally tubular column sleeve having a support housing disposed on an upper end thereof;
- providing a steering shaft;
- rotatably supporting the steering shaft within the column sleeve about a longitudinal steering axis;
- providing a tilt housing;
- pivotally connecting the tilt housing to the support housing for articulating movement about a tilt axis generally perpendicular to the longitudinal steering axis;
- said step of pivotally connecting including providing a pair of co-axially aligned fasteners extending along the tilt axis and spaced apart on opposite sides of the steering shaft, each of the fasteners having a length;
- and
- independently telescopically adjusting the length of each fastener to establish a predetermined compression condition between the support housing and the tilt housing whereby objectionable rattling noises in the column assembly can be attenuated through the deliberate and independent manipulation of the fasteners to the predetermined compression condition.
