Four-direction adjustable automobile steering column with energy absorption function

The invention relates to a four-direction adjustable automobile steering column with an energy absorption function and belongs to the technical field of automobile steering systems. The automobile steering column comprises a steering shaft assembly, an upper column tube assembly, a lower column tube assembly, a bracket assembly and an adjustment locking device, wherein the steering shaft assembly is sleeved with the upper column tube assembly and the lower column tube assembly; the upper column tube assembly and the lower column tube assembly are in interference fit with each other; the bracket assembly is arranged on the upper column tube assembly and the lower column tube assembly; one end of the bracket assembly is connected with the upper column tube assembly through the adjustment locking device, and the other end of the bracket assembly is connected with the lower column tube assembly through a locking bolt. The automobile steering column disclosed by the invention is easy to machine and high in assembling property; functions of adjusting the angle and the height of the automobile steering column and the function of absorbing energy within a longer travel range are realized; the problems that the conventional automobile steering column is low in fixed frequency, poor in driving operation handfeel, unstable in energy absorption property, lower in consistency and smaller in energy absorption distance are solved; therefore, the driving safety is improved.
