The invention provides a crumple energy absorption type automobile steering pipe column assembly and an assembling method thereof. The automobile steering pipe column assembly comprises an inner column pipe, a cylindrical precision positioning ring and an outer column pipe, wherein one end of the inner column pipe is sleeved with the cylindrical precision positioning ring, and the cylindrical precision positioning ring is sleeved with one end of the outer pipe column. The cylindrical precision positioning ring forms the convex rib interference fit state between the inner column pipe and the outer column pipe, and compensates for the fit clearance between the inner column pipe and the outer column pipe. Due to the fact that the pipe column assembly is provided with the precision positioning ring, the effects that the fit clearance between the inner column pipe and the outer column pipe is automatically compensated, and crumple energy absorption is achieved through interference fit between the inner column pipe and the outer column pipe are achieved. In addition, crushing force of the steering pipe column assembly is stable and controllable, and the yield of the volume production is improved.
