Description
Technical field
The invention belongs to motor turning manipulation technology field, be specifically related to a kind of steering column and adjusting mechanism assembly of novel pneumatic auto lock.
Background technology
Car steering tube column and adjusting mechanism assembly are assemblies important in steering swivel system, and its effect transfers torque to deflector, thus handle the sense of motion of automobile.Simultaneously self can the front and back of adjustment direction dish and upper-lower position to increase the traveling comfort of driving.
The steering column that current application is more and adjusting mechanism assembly, adopt tools for bolts ' pretension more, and the quiet power of rubbing of generation steps up column jecket by support, thus mechanism is locked.This kind of structure due to the simple of manufacturing process and properties of product stable and be widely adopted, but operation inconvenience, chaufeur just can the angle of travel direction dish and highly adjustment after must opening clamp handle with the right hand.In addition, when orthodox car steering column and the locking of adjusting mechanism assembly, the static friction Lai Shi mechanism locking that in utilization, the predetermincd tension of bolt produces, vehicle travels the vibrations brought, also support medial surface and column jecket contact surface can be made to produce the reciprocal small changing of the relative positions makes contact element wear and tear, of long duration, wear cumulation, finally causes handle locking stroke to change.In addition, owing to adopting Handleset, mechanism is taken up room more, also propose to dodge requirement to interior trimming partss such as Automobile instruments, thus make the space structure of perimeter component become complicated, space availability ratio reduces.Therefore, how to produce a kind of steering column and adjusting mechanism assembly of novel pneumatic auto lock, stable performance, simple operation, space availability ratio be high, there is longer service life, have important practical significance.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of brand-new automobile steering column adjusting mechanism, the i.e. steering column of novel pneumatic auto lock and an adjusting mechanism assembly, have stable performance, simple operation, space availability ratio high, have the advantages such as longer service life.
The technical scheme that the present invention takes is:
A kind of steering column of novel pneumatic auto lock and adjusting mechanism assembly, it is characterized in that, except comprising steering shaft 1, steering tube column jecket 2, support 5, the cylinder 7 realizing auto lock and cam assembly, described steering shaft 1 and steering tube column jecket 2 connect to form column assy, described column assy is fixedly mounted on steering column support 5 by upper bolt 3 and lower bolt 4, and steering column support 5 is fixed on auto body; The cylinder 7 of described auto lock and cam assembly composition adjusting mechanism, described cam assembly comprises right outside camshaft 11, left outside camshaft 12, shift fork 6 head and central rotating shaft 10, it is hinged that described cylinder 7 head and shift fork 6 end pass through bearing pin 9, it is hinged that cylinder 7 afterbody and steering tube column jecket 2 pass through bearing pin 9, and gas source interface 8 is connected with external pressure source.
Further, when source of the gas is connected, cylinder 7 its length shortens, shift fork 6 reverses around center shaft 10 axis, right outside camshaft 11 and left outside camshaft 12 respectively centrally axle 10 move inward, adjusting mechanism is in releasing orientation, can travel direction dish up and down before and after adjustment.
Further, when gas source switch is closed, cylinder 7 resets under contained spring effect, length elongation, promoting shift fork 6 and rotate around center shaft 10 axis, there is the relative changing of the relative positions with right outside camshaft 11, left outside camshaft 12 in shift fork 6 head, thus the right outside camshaft 11 of promotion both sides and left outside camshaft 12 move along center shaft 10 axis to both sides respectively, its both ends of the surface are pressed on steering column support 5, and now, adjusting mechanism is in locking state.
Further, the upper end closure dish of described steering shaft 1.
Further, centered by the following bolt 4 of described column assy, front and rear angles adjustment is done in rotating shaft.
Further, described cylinder 7 is the single-acting cylinder of spring reset.
Further, described shift fork 6 is lever shift fork, and its head construction is indent.
Further, shift fork 6 head in described cam assembly is arranged on centre, and right outside camshaft 11 and left outside camshaft 12 are separately positioned on both sides.
Beneficial effect of the present invention is:
1, adopt the elements such as cylinder, steering column realizes the automation of locking, tripping-gear, and during locking, locking power is from the effect of cylinder interior retracing spring; When unclamping, pneumatic supply is connected, and cylinder works, and mechanism is unclamped, compared with the steering column of conventional belt adjusting mechanism, manual with pneumatic replacement, improves the automatization level of product, adjusts easy, improve the traveling comfort driven.
2, propulsion source of the present invention and point of action are positioned at adjusting mechanism midway location, save handle arrangement compared with regulating with traditional manual, so it is little to take up room, be conducive to the layout of automotive trim, make product structure compacter, reduce assembly difficulty, improve space availability ratio.
3, rubbing effect face area increases, and reduces the component in assembly unit area, thus reduces wearing and tearing, product reliability is increased, substantially prolongs service life.
4, the present invention is by center shaft, external cam axle construction and laborsaving lever shift fork, the application force of cylinder can be amplified to and be enough to steering column support and steering column to compress, make adjusting mechanism simpler, stable, compact.
5, the single-acting cylinder of spring reset, manufacturing process is simple, reduces the cost of product, and only needs a tracheae, convenient connection.
6, cylinder is being lock between steering tube column jecket and steering column support without gas closed condition, improves the reliability of product.
