摘要： A position control apparatus for an adjustable motor vehicle steering column including a friction clamp, a control shaft rotatable between locked and unlocked positions, a hollow rectangular frame moveable relative to the control shaft when the steering column is adjusted, a first toothed pawl a second toothed pawl, and an elastic bushing resiliently supporting the first and second toothed pawls on the control shaft inside of the rectangular frame. When the control shaft is rotated to its locked position the friction clamp frictionally captures the adjusted position of the steering column. The pawls have gear sectors thereon which are relatively angularly offset by one-half tooth pitch. When the control shaft is rotated to its locked position, the one-half tooth pitch offset assures that at least one of the gear sectors will mesh with a rack gear on the rectangular frame even if the other engages the rack gear peak-to-peak. Each pawl further includes a lug which cooperates with a plain edge of the rectangular frame in immobilizing the pawl when the gear sector thereon is meshed with the rack gear so that the meshed tooth couple between the gear sector and the rack gear reinforces the friction clamp.

摘要： The vehicle steering column has a rake adjustment and a telescope adjustment. The adjustment mechanism includes a compression bracket with a telescope slot, a rake bracket with a rake slot and a rake bolt that passes through the telescope slot and the rake slot. A wedge lock is mounted on the rake bolt and positioned in the rake slot and the telescope slot. Rake and telescope teeth on the wedge lock are held out of engagement with a rake tooth rack and a telescope tooth rack during rake and telescope adjustment. The rake bolt is tightened to hold a selected adjustment position and the telescope teeth on the wedge lock engage the telescope tooth rack. During a collision the rake teeth on the wedge lock are moved into engagement with the rake tooth rack to fix the rake and telescope adjustments.

摘要： A steering column for a motor vehicle having a gear box of an electric power assist apparatus in front of the steering column. The steering column includes a rigid mast jacket consisting of a short tubular sleeve and a bracket attached to the tubular sleeve having a pair of laterally separated guides straddling the gear box. A pair of lugs on the gear box cooperate with a pair of elongated slots in the guides in connecting the mast jacket to the gear box for vertical pivotal movement and for linear translation. A longitudinally collapsible steering shaft is rotatably supported on the tubular sleeve with a steering hand wheel at one end and a flexible coupling at the other end connecting the steering shaft to an input shaft on the gear box. The tubular sleeve is connected to the vehicle body by a clamp which releases the tubular sleeve for a collapse stroke of the mast jacket. The mast jacket protects the steering shaft against beam bending during the collapse stroke. The unobstructed span in front of the tubular sleeve between the guides yields a collapse stroke of the mast jacket consistent with acceptable performance of an energy absorber.
摘要翻译： 一种用于机动车辆的转向柱，其具有在转向柱前面的电动助力装置的齿轮箱。 转向柱包括由短管状套筒和附接到管状套筒的支架组成的刚性桅杆护套，其具有跨越齿轮箱的一对横向分离的导向件。 齿轮箱上的一对凸耳与引导件中的一对细长的槽配合，将桅杆护套连接到齿轮箱，用于垂直枢转运动并进行线性平移。 纵向可折叠转向轴可旋转地支撑在管状套筒上，一端具有转向手轮，另一端的挠性联轴器将转向轴连接到齿轮箱上的输入轴。 管状套筒通过一个夹具连接到车体上，该夹具释放管状套筒以使桅杆护套的塌陷行程。 桅杆护套在塌陷行程中保护转向轴免受梁弯曲。 在导向件之间的管状套管前面的无阻挡跨度使得桅杆护套的塌陷行程与能量吸收器的可接受的性能一致。

摘要： A shaft coupling including a socket, a first shaft, a plug on a second shaft seated in the socket, and a clamp operative to clamp together the first and the second shafts in the direction of a longitudinal centerline of the shaft coupling to prevent dislodgment of the plug from the socket. The clamp includes an annular first flange on the first shaft, an annular second flange on the second shaft facing the first flange, oppositely facing frustoconical shoulders on the first and the second flanges, a plurality of clamp jaws pivotally mounted on the first shaft arrayed symmetrically around the first and the second flanges each having a closed position inducing radial thrust on the oppositely facing frustoconical shoulders, and springs biasing each of the clamp jaws toward its closed position. The oppositely facing frustoconical shoulders convert the radial thrust of the clamp jaws into linear thrust in the direction of the longitudinal centerline of the shaft coupling to force together the annular first and second flanges. A peripheral edge of the annular second flange pivots the clamp jaws to open positions against the bias of the springs to permit completion of the shaft coupling in quick-connect fashion.
