Abstract
The utility model discloses an adjustable steering pipe column having an energy absorbing function, which is the improvement of the adjustable steering pipe column of the existing automobile. The adjustable steering pipe column is characterized in that the pressing and matching structure of the upper pipe column and the lower pipe column of the adjusting steering pipe column of the existing automobile is abandoned; a single integral pipe column is adopted; the structure of an exact positioning ring and a friction sheet is also adopted, therefore, the exact positioning ring and the positioning ring base of the pipe column are connected with an installing bracket; the balanced and constant motion resistance is formed between the exact positioning ring and the positioning ring base by the interference fit of the exact positioning ring and the positioning ring base so that the dispersing degree of the crumpling force of the pipe column is small, thus the kinetic energy of the collision of automobiles is effectively reduced, and the running safety of a driver is ensured.
Description
Technical field:
The utility model relates to a kind of adjustable steering pipe column with energy-absorbing function, belongs to The Design of Auto Parts, manufacturing technology field.
Background technology:
The energy-absorbing adjustable steering pipe column is to be used to protect driver safety to travel on the automobile, alleviates vehicle collision kinetic energy, one of important device of protection driver safety.At present, the safe energy absorption device of the energy-absorbing adjustable steering pipe column of domestic production generally all adopts upper and lower column jecket to be press-fitted formation, be that upper and lower column jecket cooperates the back to press 4～8 alternate impressions that do not wait at the lower prop tube-surface, make the certain moving resistance of formation between column jecket, thereby play the effect of safety collision, the contract dispersion of the power of bursting of this kind structure column jecket is big, can not well bring into play the function of safety collision.
Summary of the invention:
In view of the problem of above-mentioned existence, the purpose of this utility model provides a kind of simple in structure, and the contract dispersion of the power of bursting of column jecket is less, can effectively reduce a kind of adjustable steering pipe column with energy-absorbing function of vehicle collision kinetic energy.
For achieving the above object, the utility model has been taked following technical measures:
A kind of adjustable steering pipe column described in the utility model with energy-absorbing function; abandoned the upper and lower column jecket press-fit structure of existing automobile adjustable steering pipe column; adopted single integral type column jecket; and cooperate the structure of a precise placement circle and friction lining; column jecket precise placement circle and ring support Tongan City, location dress support are connected; by precise placement circle and column jecket interference fit; between forms steady, constant moving resistance; make column jecket contract to burst that the dispersion of power is less; thereby reduced vehicle collision kinetic energy effectively, guaranteed the driving safety of protection chaufeur.

The specific embodiment:
A kind of adjustable steering pipe column with energy-absorbing function described in the utility model comprises changes upward axis 1, combined switch support 2, column jecket 3, regulate support 4, turn to lower shaft 6, mounting bracket 9 and joint yoke 10; Column jecket 3 is single one-piece construction, regulates support 4 and mounting bracket 9 and is installed on the column jecket 3; Regulate on the support 4, a friction lining 5 is housed; Regulating support 4 and friction lining 5 usefulness bolts and vehicle body links; In the end of column jecket 3, be provided with a location ring support 8, precise placement circle 7 and column jecket 3 are interference fit; Mounting bracket 9 links by precise placement circle 7 and column jecket 3; Mounting bracket 9 connects with vehicle body by a cotter axle.Steering shaft divides to be changeed upward axis 1 and turns to lower shaft 6 two parts, and turning to lower shaft is hollow shaft, and last axle is a solid axle, and both connect by injection moulding, changes upward axis and adopts spline and screw thread to connect with bearing circle.
Described friction lining 5 adopts the 65Mn steel plate to be stamped to form, and higher elasticity and hardness are arranged; Precise placement circle 7 is adopted as sheet steel and makes, and has elasticity; On precise placement circle 7, be provided with many axial convex rib structures, axial moving force is reliable and the gyratory directions rotating torque is big, can not rotate in transportation and the operation transhipment and loosening.
Concrete working process of the present utility model is achieved like this:
When vehicle is subjected to external shar pounding; crumple power reaches after the setting value; precise placement circle 7 produces relative displacement together with location ring support 8 and column jecket 3; friction lining 5 breaks away from mounting bracket simultaneously, changes the injection molding body fracture between upward axis and the lower shaft, in the last axle indentation lower shaft; bearing circle sinks along with the sinking of column jecket together with changeing upward axis like this; absorb impact energy, protect chaufeur, thereby realized the function of safety collision.
