Abstract
The utility model discloses a novel steering tubular column crumple energy absorption structure. The generally unreliable injection molding connection of upper and lower steering spindles is changed into frictional connection using a wavelike spring leaf (5) in the upper and lower spindles, so that the requirement of a crumple force value curve of crumple force transferred to a steering tubular column during vehicle crash can be met, and the wavelike spring leaf (5) can be repeatedly used.
Description
Technical field
The utility model belongs to the automobile steering system apparatus field, relates in particular to a kind of Novel steering column crumple endergonic structure.
Background technology
At present, in known technology, have with the akin technologic material of the utility model technique effect: CN201010568682.8 energy-absorbing steering tubular column, CN200720196478.1 automobile turning pipe pillar assembly, their main structures be up and down column jecket, mandrel, crumple pull piece up and down, can realize steering column crumple requirement by this technology, but their shortcoming is that reliability, practical and convenient property and reusability aspect are not strong, and mandrel is poor by the injection moulding connection reliability up and down for steering column.
The utility model content
Technical problem to be solved in the utility model provides and a kind ofly satisfies that the crumple power value curve that car load when collision distribute to steering column requires, reliability is high and can reusable Novel steering column crumple endergonic structure.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of Novel steering column crumple endergonic structure, comprise and turn to mandrel, upper column jecket, turn to lower mandrel and lower column jecket, the described mandrel that turns to is installed in the upper column jecket by bearing, describedly turn to lower mandrel to be installed in the lower column jecket by bearing, described upper prop pipe box is contained on the lower column jecket, described upper column jecket and lower column jecket can relative slidings, described turn to mandrel and turn between the lower mandrel connect by the wavy spring sheet.
The described mandrel that turns to stretches in the described lower column jecket, and described wavy spring sheet is contained in the lower prop pipe.
The compartment of terrain arranges a series of through holes on the described wavy spring sheet.
Described upper column jecket is provided with and pulls piece.
Described lower column jecket is connected with lower bracket.
The utility model has the advantage of, the crumple power value curve of distributing to steering column in the time of can realizing satisfying the car load collision requires and the wavy spring sheet can repeated usage.

Mark among the above-mentioned figure is: 1, turn to mandrel, 2, pull piece, 3, upper column jecket, 4, lower column jecket, 5, the wavy spring sheet, 6, lower bracket, 7, turn to lower mandrel, 8, through hole.
The specific embodiment
Fig. 1 is the structural representation of a kind of Novel steering column crumple of the utility model endergonic structure, comprise and turn to mandrel 1, upper column jecket 3, turn to lower mandrel 7 and lower column jecket 4, turn to mandrel 1 to be installed in the upper column jecket 3 by bearing, turn to lower mandrel 7 to be installed in the lower column jecket 4 by bearing, upper column jecket 3 is sleeved on the lower column jecket 4, upper column jecket 3 and lower column jecket 4 can relative slidings, turn to mandrel 1 and turn between the lower mandrel 7 to connect by wavy spring sheet 5.Upper column jecket 3 is provided with and pulls piece 2.Lower column jecket 4 is connected with lower bracket 6.
Fig. 2 and Fig. 4 are the structural representation of wavy spring sheet, and the compartment of terrain arranges a series of through holes 8 on the wavy spring sheet 5.
Fig. 3 is for turning to up and down mandrel matching part partial enlarged drawing, turn to mandrel 1 to stretch in the lower column jecket 4, wavy spring sheet 5 is contained in the lower column jecket 4, on turning to mandrel 1 be pressed into wavy spring sheet 5 between the hole axle that turns to lower mandrel 7 cooperates, turn to mandrel 1 and turn to lower mandrel 7 to be the cooperation of hole axle, wavy spring sheet 5 is pressed into and turns to mandrel 1 and turn between the lower mandrel 7.
By pull piece 2 and lower bracket 6 up and down column jecket be fixed on the vehicle body, be pressed into certain degree of depth in the outside of upper column jecket 3 after during assembling upper column jecket 3 being fixed with lower column jecket 4 positions, with lower column jecket 4 secure fit; Be pressed into wavy spring sheet 5 when on turning to, cooperating between mandrel 1 and the hole axle that turns to lower mandrel 7.In order to satisfy different crushing force curve requirements, can adjust the material of wavy spring sheet 5 and the height of thickness and wavy spring sheet 5 waveforms.When car load bumps when safe; chaufeur indirectly is delivered to power by bearing circle and turns on the upper mandrel 1; pull simultaneously that piece 2 separates with body fixing point, crimp occurs in mandrel 1 and the relative displacement that turns to lower mandrel 7 in upper column jecket 3 and lower column jecket 4 beginning relative slidings, wavy spring sheet 5 on turning to; these continuous actions make chaufeur be converted into the power that makes the steering column crumple to the impulsive force that bearing circle produces; along with the lower of steering column burst and movement, bearing circle is protected the safety of chaufeur automatically to abdicate enough spaces away from chaufeur.
After adopting such structure, the crumple power value curve of distributing to steering column in the time of can realizing satisfying the car load collision requires and wavy spring sheet 5 can repeated usage, and each position crumple power value size of reasonable distribution.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
