Clamp assembly for a steering column assembly |
摘要 |
An adjustable steering column assembly includes a releasable clamp assembly that clamps a shroud of the assembly in position relative to a support bracket, the clamp assembly including an elongate clamp bolt onto which are stacked:
at least a part of an adjustable shroud of the steering assembly, anda cam mechanism comprising a fixed cam part and a moving cam part, the two parts each having a bore through which the clamp bolt passes,a thrust bearing,and a locking nut which includes an internal thread that engages a complimentary thread on the clamp bolt and which is locked down so as to apply an axial load to the thrust bearing. The assembly also includes a tapered compliant bush which is pressed into a space defined between the clamp bolt and the bore of the moving cam part of the cam mechanism with the relatively thick end of the bush nearest the thrust bearing and with the thrust bearing applying an axial load to the bush. |
