Abstract
The utility model relates to a column assembly, in particular to an energy-absorbing angle-adjustable automotive steering column assembly, which comprises a transmission shaft connected with an adjusting support. The transmission shaft and the adjusting support are fixed with each other through a universal joint fork, a lower universal joint fork is arranged at the other end of the adjusting support, and a tension spring sleeve is sleeved outside the transmission shaft. An elastic rubber needle roller assembly is disposed between the tension spring sleeve and the tail of the transmission shaft, and the head of the transmission shaft is fixedly connected with the tension spring sleeve through a ball bearing. The energy-absorbing angle-adjustable automotive steering column assembly is simple in structure, high in stability, convenient in operation and high in damping capacity.
Description
Technical field
The utility model patent relates to a kind of tubing string assembly, relates in particular to a kind of car steering tube column assembly of energy-absorbing angle adjustable.
Background technology
