Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of regulating mechanism, particularly a kind of regulating mechanism of car steering tube column crumple confining force.
Background technology
Along with automobile popularizing in people's life, people increase the requirement of vehicle safety and traveling comfort day by day.Because the safe energy absorption characteristics of steering column is called as " last line of defense " of driver safety, in the manufacturing process of automobile, be necessary so improve the energy absorption characteristics of steering column.
When collision happens, steering column can move under the effect that receives external force backward, and simultaneously chaufeur be because of the inertia that has forward can move to steering column, makes the impact of chaufeur and bearing circle and comes to harm.Receive such injury for fear of chaufeur, this just requires car steering tube column that crumple can take place and also can absorb energy simultaneously.Be installed on the adjustable for height steering column on the automobile for existing, its crumple process generally is divided into two stages: 1, chaufeur bump steering column makes steering column be retracted to the nadir of height adjustment; 2, steering column from the nadir crumple of height adjustment to end position.
For the regulating mechanism of existing car steering tube column,, find like the Chinese patent document and disclose a kind of steering column direction adjustment organization [patent No.: ZL200820122311.5 through retrieval; Granted publication number: CN201264640Y].This regulating mechanism; Comprise tubing string seam assembly; Should go up tubing string seam assembly upper end and be embedded with the adjusted support through bearing pin; Be connected with left adjusting cam and right adjusting cam respectively in the both sides of last tubing string seam assembly, this adjusting cam outside, left side is connected with the adjusting spanner, and this adjusting spanner outside is connected with regulating handle.This regulates spanner through jam nut captive joint left side adjusting cam, can change the crumple power of steering column through the adjusting lock nut.
For this steering column direction adjustment organization, when rotating the regulating handle jam nut, cam squeeze adjustments support, thus make that regulating support clamps compressed stent.Usually; The crumple confining force of F/s normally keeps with the handle cam mechanism; This cam mechanism can only make the crumple confining force of F/s usually about 600N, if we have higher requirement to the crumple confining force of F/s, as about 1000N; Then need tighten jam nut, increase the crumple confining force of steering column.And when tightening jam nut, reduced cam and the spacing of regulating support; Behind the locking regulating handle; Cam more gets the squeeze adjustments support, thereby obtains bigger crumple confining force, and chaufeur needs bigger power could lock regulating handle simultaneously; Make chaufeur be difficult to rotary handle to the position of unclamping and locking, this can't satisfy the requirement of crew comfort.
Summary of the invention
