Lower prop pipe assembly 3 is made up of lower column jecket 16, lower prop pipe bracket 17 and deep groove ball bearing B18, one end of lower column jecket 16 is symmetrically installed with lower prop pipe bracket 17, between lower prop pipe bracket 17, the port of lower column jecket 16 one end built with deep groove ball bearing B18, the circumferential outer surface of lower column jecket 16 other end is evenly equipped with the connection keyway 19 corresponding with connecting key; Lower prop pipe bracket 17 is symmetrically arranged with assembly opening 20(see accompanying drawing 4).
Interference is coordinated to be connected by the connection keyway 19 on lower column jecket 16 with the connecting key on upper column jecket 10 between upper prop pipe assembly 2 and lower prop pipe assembly 3.Upper prop pipe assembly 2 and lower prop pipe assembly 3 are provided with bracket assembly 4.Bracket assembly 4 is made up of lock bracket 21, bracing frame 22, connection plate 23, lock screw 24 and lock washer 25; One end bilateral symmetry of bracing frame 22 is provided with the adapter plate 27 with mounting hole 26, bracing frame 22 between adapter plate 27 is symmetrically arranged with crumple chute 28, the bracing frame 22 of crumple chute 28 upper surface is equipped with lock washer 25, the bracing frame 22 of crumple chute 28 lower surface is equipped with lock bracket 21.Lock bracket 21, in " ∪ " shape, lock bracket 21 is symmetrically arranged with installation opening 29.Lock bracket 21 is fixedly connected with lock washer 25 through crumple chute 28 by lock screw 24.The upper surface of bracing frame 22 other end has been welded connection plate 23, connection plate 23 is provided with mounting hole 26, the bracing frame 22 below connection plate 23 is symmetrically arranged with and connects chute 31(see accompanying drawing 5-6).
Regulation locking device 5 is made up of adapter shaft 32, latch segment 33, operating handle 34, jam nut 35 and crank 36.Operating handle 34 is equipped with in one end of crank 36, and the other end of crank 36 is provided with adapter shaft 32 by jam nut 35, and the termination of adapter shaft 32 is provided with assembling side's plate 30, and the adapter shaft 32 of contiguous crank 36 is equipped with latch segment 33(see accompanying drawing 7).Latch segment 33 can rotate around adapter shaft 32 axis.
One end of bracket assembly 4 is connected with upper prop pipe assembly 2 by regulation locking device 5, and the other end of bracket assembly 4 is connected with lower prop pipe assembly 3 by lock bolt.
This concrete assembling process of each parts with the four-way adjustable automobile steering column of energy-absorbing function is, first upper prop pipe assembly 2 and lower prop pipe assembly 3 are set on the upper steering shaft 9 of steering shaft assembly 1 respectively by upper column jecket 10 and deep groove ball bearing A and lower column jecket 16 and deep groove ball bearing B18, between upper prop pipe assembly 2 and lower prop pipe assembly 3, coordinate interference to be connected by the connection keyway 19 on lower column jecket 16 with the connecting key on upper column jecket 10.Then the column jecket support 12 of upper prop pipe assembly 2 is positioned in the lock bracket 21 of bracket assembly 4, and the assembling chute 15 of column jecket support 12 is alignd with the installation opening 29 of lock bracket 21, again the adapter shaft 32 of regulation locking device 5 is penetrated in assembling chute 15 and installation opening 29, make the assembling side's plate 30 on adapter shaft 32 and latch segment 33 lay respectively in the installation opening 29 of lock bracket 21 both sides simultaneously, thus complete the connection of upper prop pipe assembly 2 and bracket assembly 4.
After upper prop pipe assembly 2 and the assembling of bracket assembly 4 complete, between the connection chute 31 lower prop pipe bracket 17 of lower prop pipe assembly 3 being positioned over bracket assembly 4, and make the assembly opening 20 of lower prop pipe bracket 17 and be connected chute 31 and align, again lock bolt is penetrated to assembly opening 20 be connected in chute 31, thus complete assembling of lower prop pipe assembly 3 and bracket assembly 4.
This four-way adjustable automobile steering column with energy-absorbing function is fixedly installed on car body by the mounting hole 26 of bracket assembly 4.In working process, when pulling the rigidity that effectively can ensure this car steering tube column when operating handle 34 makes regulation locking device 5 locking, to ensure the safety and reliability of driving a vehicle.When pulling after operating handle 34 makes regulation locking device 5 open, the diameter of axle of steering shaft assembly 1 applies load up or down, this car steering tube column can be that pivot point rotates with lock bolt within the scope of the chute of bracket assembly 4 lock bracket 21, realize the angle of this car steering tube column upwards, downward adjustable function.In like manner, apply load forward or backward in the axis of steering shaft assembly 1, upper prop pipe assembly 2, lower prop pipe assembly 3 can simultaneously along assembling chute 15 and the height adjustable functions being connected chute 31 and realizing forward, backward.The principle of work of regulation locking device 5 drives latch segment 33 to rotate around adapter shaft 32 axis by operating handle 34, locked and unclamp by the flange mechanism of latch segment 33 liang of fitting surfaces.Both the locking function of steering column be can realize, angle, height adjustable function after also can opening, realized smoothly.
In complete automobile collision process, when the external load imposing on upper steering shaft 9 is greater than the energy-absorbing power of bracket assembly 4 (after lock screw 24 locking, the friction force of lock washer 25 and bracing frame 22, and the locking confining force of regulation locking device 5) time, bracket assembly 4 starts crumple energy-absorbing, drives lower prop pipe assembly 3 to move down, when column jecket assembly 3 is displaced to lower limit position instantly simultaneously, upper prop pipe assembly 2 and lower prop pipe assembly 3 start crumple energy-absorbing, realize secondary energy-absorbing function.And energy-absorbing power is stablized, conformability is good, and natural frequency is high, improve manipulation feel, solve existing car steering tube column natural frequency low, it is poor that feel is handled in driving, the problem that energy-absorbing power is unstable, conformability is poor and energy-absorbing distance is less, and then improve traffic safety performance.
