| description | The utility model relates to an energy-absorption structure, in particular to an energy-absorption structure of an automobile steering column. The energy-absorption structure of the automobile steering column comprises an upper column pipe, a lower column pipe and a rolling bearing, wherein the lower column pipe is sleeved in the upper column pipe, and the rolling bearing is arranged between the upper column pipe and the lower column pipe. By means of point-contact type interference fit, contact areas are reduced, shape and position errors of parts and components are eliminated, and therefore assembly uniformity is improved. Namely, manufacture accuracy of energy-absorption ability is improved and safe energy-absorption can be achieved. The energy-absorption structure of the automobile steering column solves the problems that in the prior art energy-absorption ability is unstable, uniformity is poor, and demands on column pipe matching size accuracy and craft and processing level are high, and therefore produ |
