Description
Technical field
The utility model relates to automobile steering systems, and in particular to a kind of crumple mechanism of car steering tube column.
Background technique
When violent shock occurs for automobile, driver is often because strong fails and turn forward, the chest of human body
Portion can collide with steering wheel, have the requirement of crumple for steering column at present for protection driver, with automobile industry
Continuous development and automotive performance continuous improvement, for driver protection also in the weight by more vehicle factors and client
Depending on for the crumple performance of steering column, more stringent requirements are proposed.
The collapsing structure working principle of steering column is as follows at present: when a vehicle is in a collision, input shaft will receive driving
Member's bring impact, will form an axial force along input shaft, this axial force will form crumple block and tubular column bracket is detached from,
Crumple block is kept fixed with vehicle overarm brace, tubular column bracket, input shaft, outer tube column casing can crumple axially downward, absorb punching
Bring energy is hit, to play the role of protecting driver.
But there are the following problems for this mechanism at present:
1, the crumple power of this collapsing structure is formed by three parts:
1), the breakaway force between crumple block and tubular column bracket, power is generally 1500N or more at this；
2), the crumple power between input shaft and coupling spindle, power is generally in 1500N or more at this；
3), the crumple power between outer tube column casing and inner tube column casing, power 2000N or more at this；
The resultant force of these three power is about in 5000N or more, and power is larger herein, insufficient to the protection of driver.
2, after disengaging from vehicle crossbeam when tubular column main body, tubing string can be rotated around rotary shaft under gravity, be caused
Tubular column main body, which falls, causes time injury to driver, while above-mentioned crumple power is caused more in tubular column main body whereabouts during crumple
It is big and more unstable, can not effective protection to driver.
