Fig. 1 is the overall structure scheme drawing of Pneumatic control adjustment steering column for automobiles of the present invention.
Fig. 2 is the inner structure scheme drawing of Pneumatic control adjustment steering column for automobiles of the present invention.
Among the figure:
(5) specific embodiment
Referring to Fig. 1～2, Fig. 1 is the overall structure scheme drawing of Pneumatic control adjustment steering column for automobiles of the present invention.Fig. 2 is the inner structure scheme drawing of Pneumatic control adjustment steering column for automobiles of the present invention.By Fig. 1 and Fig. 2 as can be seen, Pneumatic control adjustment steering column for automobiles of the present invention, comprise steering shaft 5, steering-column tube 4, adjustable support 3, fixed support 2 and cylinder 1, described steering shaft 5 by bearing installation in steering-column tube 4, steering shaft 5 lower ends are fixed with back-up ring, prevent steering shaft end float misalignment in steering-column tube 4, steering shaft 5 one ends stretch out outside the steering-column tube 4, and the relative steering-column tube 4 of steering shaft can only rotate.Steering-column tube 4 is arranged in the endoporus of adjustable support 3, with the endoporus of adjustable support 3 be bearing fit, adjustable support 3 is hinged by long column pin 6 and fixed support 2, adjustable support can only rotatablely move before and after interior this long column pin relative fixed support is done.On steering-column tube 4 outside wall surface, be fixedly connected with a passive keep plate II 17, have elongated slot on this passive keep plate II 17, be provided with an active hold-down column 16 that matches with this elongated slot in the elongated slot, initiatively hold-down column 16 not only plays pressuring action but also play the positioning and guiding effect.Initiatively hold-down column 16 the inners contact with described elongated slot, initiatively pass the endoporus hole wall of described adjustable support 3 in the middle of the hold-down column 16, and and the endoporus hole wall of described adjustable support 3 between can slide relative, initiatively be set with pull back spring II 15 on the hold-down column 16, this pull back spring II 15 can realize separating of active hold-down column 16 and passive keep plate II 17, initiatively the outer end of hold-down column 16 contacts with a working plate II 14 1 end inboards, the cooperation that contacts of working plate II 14 other ends one end inboard and that the cylinder of cylinder 1 pushes away core 13, the centre of working plate II 14 is tightened on the endoporus hole wall of described adjustable support 3 by a pivot bolt 10, and plays point action.Thus, constitute an engaging mechanism II 18 between described steering-column tube 4, adjustable support 3, active hold-down column 16, pull back spring II 15 and the working plate II 14.
On described fixed support 2, have an oval deep-slotted chip breaker, in this oval deep-slotted chip breaker, be provided with a passive keep plate I 8, the cooperation that contacts with the outside wall surface of described adjustable support 3 of the medial surface of passive keep plate I 8, the lateral surface of passive keep plate I 8 and initiatively keep plate I 9 cooperation that contacts, initiatively keep plate I 9 cooperation that contacts with the end inboard of a working plate I 12, and with a passive hold-down column with the end of described working plate I 12, initiatively keep plate I 9 and passive keep plate I 8 cross-under, and be set with a pull back spring I 11 on this passive hold-down column.The cooperation that contacts of the other end of working plate I 12 other end inboard and that the cylinder of described cylinder 1 pushes away core 13, the centre of working plate I 12 is tightened on the adjustable support 3 by another pivot bolt 10, and a point action.Thus, constitute an engaging mechanism I 7 between described steering-column tube 4, adjustable support 3, passive keep plate I 8, active keep plate I 9, pull back spring I 11 and the working plate I 12.
Concrete adjusting control principle up and down: when cylinder feeds source of the gas, cylinder pushes away core 13 inside indentations, working plate II 14 is not stressed and is in releasing orientation at this moment, the other end does not compress the active hold-down column 16 at engaging mechanism II 18 positions, just initiatively hold-down column 16 and passive keep plate II 17 are in by the elasticity of pull back spring II15 and separate releasing orientation, linear slide about at this moment the steering-column tube 4 that links to each other with passive keep plate II 17 just can carry out.And when steering-column tube is adjusted to correct position, the shifter cylinder source of the gas, this moment cylinder to push away core extrapolated automatically under the cylinder interior action of the spring, thereby plate II 14 lower ends that push the work forward are around pivot bolt 10 swings, working plate II 14 tops are moved to steering-column tube 4 centers, thereby press to initiatively hold-down column, make active hold-down column and passive keep plate II 17 be in impaction state, steering-column tube is maintained the lock status.
Concrete fore-and-aft direction adjusting control principle:
When cylinder feeds source of the gas, cylinder pushes away the inside indentation of core, working plate I 12 is not stressed and is in releasing orientation at this moment, the other end does not compress the active keep plate I 9 at engaging mechanism I 7 positions, just initiatively keep plate I 9 and passive keep plate I 8 are in by the elasticity of pull back spring I 11 and separate releasing orientation, but at this moment with the relative adjustable support of fixed support that passive keep plate I 8 links to each other between relative motion, just adjustable support can rotate around the long column pin, simultaneously by passive keep plate I 8 inside grooves restriction rotational angle.And when adjustable support is adjusted to correct position, shifter cylinder 1 source of the gas, this moment cylinder to push away core extrapolated automatically under the cylinder interior action of the spring, thereby the plate I 12 that pushes the work forward is around another pivot bolt 10 swings, working plate I 12 other ends are moved to steering-column tube 4 centers, thereby press to initiatively keep plate I 9, make active keep plate I 9 and passive keep plate I 8 be in impaction state, steering-column tube is maintained the lock status.
