摘要： An actively variable energy absorber including a convex anvil on a steering column housing, a flat metal strap attached to a steering column support and slidably engaging the convex anvil on an active surface area of the convex anvil, and a control apparatus for actively varying the geometric relationship between the flat metal strap and the convex anvil in response to changes in a control variable thereby to adjust the magnitude of the active surface area. Adjusting the magnitude of the active surface area changes the severity of plastic deformation of the flat metal strap and the magnitude of the friction between the flat metal strap and the convex anvil thereby to adjust the force resisting linear translation of the steering column housing. In some embodiments of the actively variable energy absorber, the flat metal strap is plastically deformed by being pulled over a single convex anvil during linear translation of the steering column housing. In other embodiments of the actively variable energy absorber, the flat metal strap is plastically deformed by being pulled across a plurality of convex anvils or by being pulled edgewise between a pair convex anvils.

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。
