The invention discloses a clamping mechanism of an automobile steering column. The clamping mechanism comprises a shaft rod, a rotating handle capable of driving the shaft rod to rotate is arranged atone end of the shaft rod, the other end of the shaft rod is sequentially sleeved with a first pressing plate and a second pressing plate on the rod body from inside to outside, and the second pressing plate is fixedly connected to the shaft rod; one or more bulges are arranged on the plate surface, facing the second pressing plate, of the first pressing plate, and the one or more bulges have at least two bulge heights; rollers are arranged on the second pressing plate, rolling shafts of the rollers perpendicularly intersect with rotating shafts of the shaft rods, and the rolling surfaces of the rollers are kept in contact with one side surface of the first pressing plate where the bulges are located when the clamping mechanism is in a pre-clamping state; when the second pressing plate rotates relative to the first pressing plate, the bulges intersect with the rollers in stroke.
本发明公开了一种汽车转向管柱的夹紧机构,包括一轴杆,所述轴杆的一端安置有一可带动轴杆转动的旋转手柄,所述轴杆的另一端由内至外在杆体上依次套设有第一压紧板和第二压紧板,所述第二压紧板与所述轴杆固定连接;所述第一压紧板朝向第二压紧板的板面上设有一个以上凸起物,所述一个以上的凸起物至少具有两种凸起高度;所述第二压紧板上设有滚轮,所述滚轮的滚轴与所述轴杆的转轴垂直相交,并保持该夹紧机构在预夹紧状态下所述滚轮的滚面与所述凸起物所处的所述第一压紧板的一侧板面相触接;所述第二压紧板相对于所述第一压紧板相对转动时,所述凸起物与所述滚轮的行程有交叉。
