摘要： 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.

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.

摘要： An energy-absorbing device for a steering column of an automotive vehicle comprising energy-absorbing straps on opposite sides of the steering column. The straps are made of relatively stiff, bendable, flexible strip material. Each strap has a laterally inner leg and a laterally outer leg secured to the inner leg by one or more rivets. The legs of each strap extend lengthwise of the steering column and have corresponding ends laterally connected together by a curved loop portion. The inner leg of each strap is rigidly connected to the steering column. The outer leg of each strap is rigidly connected to the instrument panel. The rivets are adapted to shear in a frontal impact to allow the inner leg of each strap to move with the steering column as it collapses, with the loop portion of each strap resisting such collapse to gradually absorb energy and prevent excessive reaction forces of the steering column against the driver.

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.

摘要： A vehicle steering mechanism can be supported for controlled collapse in crash situations, by constructing the steering shaft support housing as a rigid assembly having a metal die casting and tubular steel shroud as the principal components. 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. The shaft housing deflection is effectively snubbed by a friction ring encircling a lower portion of the tubular steel shroud.
