摘要:
A vehicle steering mechanism can be supported for controlled collapse in crash situations, by constructing the support mechanism as a rigid assembly having a metal die casting as a principal component. The rigid die casting transmits a shock force from the vehicle steering wheel to shearable fasteners that connect the die casting to a mounting structure on the vehicle. Undesired resilience or spring in the steering shaft support mechanism is eliminated, such that the system has a desired predictability in frontal crash situations.

A steering column support having a bracket on the steering column secured to vehicle support structure by fasteners at the rear edge of the bracket. Isolator pads at the front edge of the bracket are clamped under pressure between the bracket and the support structure The isolator pads dampen vibration of the steering column and also prevent undesirable tilting or rocking of the steering column when the vehicle is in motion.

A steering column mounting bracket is provided with break-away bars integrally formed therewith to allow for a consistent break-away force and reduce noise in the cabin of an automobile. The break-away bars will allow for axial compression of the steering shaft during an accident involving a collision of an automobile.

A universal joint for a tilt steering column of a vehicle includes an intermediate cup pivotally coupled to an end of a driven shaft, and a bell yoke receiving the intermediate cup within a cavity of the bell yoke. A pin extends from the bell yoke into an aperture of the intermediate cup. A layered bushing is compressed between an end of the pin and the aperture of the intermediate cup. The layered bushing is comprised of a mesh main body having a radially inner sliding layer and a radially outer gripping layer.

A lower bearing assembly for supporting a steering shaft within a tubular jacket of an automotive steering column. The steering shaft is of double-D configuration having two diametrically opposite, arcuate side walls and two diametrically opposite parallel flats. A cup is fitted within the jacket having a hole in the bottom wall through which the steering shaft extends. A bearing within the cup supports the steering shaft for rotation. A wedge is sleeved on the steering shaft and has a tapered nose wedged between the bearing and the steering shaft. The wedge has an inner double-D configuration matching that of the steering shaft. A compression coil spring encircles the wedge and bears on a flange on the wedge to hold the nose of the wedge wedged tightly between the bearing and the steering shaft. A retaining ring is sleeved on the steering shaft and holds the spring under compression. The inner edge of the retaining ring has the same double-D configuration as the steering shaft.

A damping pad for use with a steering column bracket includes a body having a plurality of ribs formed thereon. A plurality of retention posts extend from the body and have a hollow central shaft and a plurality of wings extending radially outwardly therefrom. The wings extend outwardly in a spiral and have a reduced cross section from the hollow central shaft out to an extremity of the wings.

A telescoping steering column is provided with a simple means to allow ease of movement of a telescoping steering shaft through a plurality of positions. This is accomplished by placing a biasing component on an exterior of a movable portion of the steering column to bias the movement of that portion.
摘要:
A device for rotatably supporting a gear shift tube within a tubular steering column of an automotive vehicle. The device comprises a support of integral, one-piece construction made of an elastomeric, resinous plastic material disposed within a cup rigidly secured in the lower end of the steering column. The support comprises an open-ended bearing sleeve co-axial with the cup having an end portion extending through an opening in the bottom wall of the cup. The sleeve has angularly spaced abutments inside the cup abutting the inner surface of the bottom wall of the cup around the opening. The sleeve also has angularly spaced tangs outside the cup extending radially outwardly and abutting the outer surface of the bottom wall of the cup around the opening. The abutments and the tangs cooperate in locking the bearing sleeve axially within the cup. The bearing sleeve is preferably made of urethane reinforced with glass fibers. A suitable lubricant, such as mineral oil, may also be incorporated into the material of which the sleeve is made. TEFLON may be added to the material of which the sleeve is made to reduce noise and permit smoother rotation of the gear shift tube.

A steering column mounting bracket is provided with break-away capsules integrally formed therewith from the same material as the mounting bracket allowing the capsules to have a more consistent break-away load and reduce noise within the cabin of a vehicle.
摘要:
The present invention provides a way in which the coefficient of friction between the steering column and the instrument panel may be lessened when an isolator pad is used. The reduction in friction is accomplished by impregnating the isolator pad with a lubricant.
