The utility model relates to a high-stability crumple structure for a
steering column. Comprising an inner column
pipe, an outer column
pipe, a tolerance ring, a pulling
rivet and a guide nail, the tolerance ring is pressed between the inner column
pipe and the outer column pipe in an interference mode, the inner end of the tolerance ring abuts against a step in the outer column pipe, a plurality of protrusions are machined on the tolerance ring, an avoiding opening is formed in the tolerance ring in the
axial length direction, and the inner end of the tolerance ring abuts against a step in the outer column pipe. A guide nail is fixed to the position, corresponding to the receding opening in the tolerance ring, of the inner column pipe through a bolt, a long hole is longitudinally formed in the outer column pipe, the guide nail is arranged in the long hole and is in
interference fit with the long hole, and the
rivet penetrates through the outer column pipe, the receding opening in the tolerance ring and the inner column pipe to connect the outer column pipe with the inner column pipe. The crumple structure is higher in stability and has guidance quality, and the crumple force
peak value can be adjusted by replacing rivets. The structure is simple, the number of parts is small, and popularization is easier.
