Background technology:
The adjustable steering column that adopts in the automobile steering system generally has only angle regulating function at present, and the less and complex structure of height adjustment function is arranged, and require the working accuracy of spare and accessory parts higher, and regulatory function is unreliable, the fault rate height.
Summary of the invention:
The purpose of this utility model is to provide a kind of simple in structure at the deficiency of prior art existence, makes easily, and existing steering wheel angle regulatory function has bearing circle height adjustment function again, also has the adjustable steering pipe column of the self-propelled vehicle of safe energy-absorbing function simultaneously.
The utility model is achieved through the following technical solutions:
A kind of adjustable steering pipe column of self-propelled vehicle comprises steering shaft and steering shaft sleeve pipe, connects by the free-sliding spline duplicate invoice between steering shaft and the steering shaft sleeve pipe, it is characterized in that:
Steering shaft is contained on one in the tubing string by antifriction-bearing box, and the steering shaft sleeve pipe is contained in the lower tubular column by antifriction-bearing box;
Last tubing string is placed in the lower tubular column, between last tubing string and lower tubular column slip cap is housed, and the lower tubular column front end has axial long rabbet (being that elongated slot section cross sectional shape is non-closed circular), and slip cap has axial pass trough mouth (being that the slip cap cross sectional shape is non-closed circular);
Elongated slot section outer wall at lower tubular column is provided with locking and regulating device.
Further scheme is: be fixed with the articulated stand of band chute on the outer wall of lower tubular column lower end, in this chute mount pin be housed.
Further scheme is: locking and regulating device comprises the U-shaped adjusting bracket component (this bracket component is fixed on the vehicle body) of the elongated slot section outer wall that is enclosed within lower tubular column, the open end both sides that U-shaped is regulated bracket component have arc chute, the center of circle of this circular arc is the mount pin center, after having a connecting screw rod to pass the arc chute of U-shaped adjusting bracket component, be set with a pair of end face adjusting cam in tape spool hole successively to dress, the release handle in tape spool hole and jam nut, the back side of described end face adjusting cam is provided with the rectangle projection along the axis hole periphery, end face upper edge, front periphery is evenly equipped with N (being generally 2-4) angle spacing block set, be evenly equipped with N the plane convex body of being with the inclined-plane that climbs in the end face of front, axis hole shape on the release handle is consistent with the shape of rectangle projection, the rectangle projection of one of them end face adjusting cam is fitted in the axis hole interior (making release handle and this end face adjusting cam relative fixed all the time) of release handle, the rectangle projection of another end face adjusting cam is positioned at U-shaped and regulates the arc chute of a side of bracket component (this end face adjusting cam can not be subjected to displacement with U-shaped adjusting bracket component separately and can only be with connecting screw rod synchronous and U-shaped adjusting bracket component be subjected to displacement), and the front end face of two end face adjusting cams is meshing with each other.
Further scheme is: be fixed with the U-shaped permanent seat on the elongated slot section outer wall of lower tubular column, the open end inboard of bracket component is regulated in the U-shaped fixed seating in U-shaped.The U-shaped permanent seat also can the tape spool hole and is sleeved on the connecting screw rod.
Further scheme is: regulate being fixed with injection moulding insert (this bracket component is inserted by injection moulding and is fixed on the vehicle body) on the bracket component outer wall at U-shaped.
Further scheme is: regulate on the bracket component being fixed with buffering stand (the buffering stand other end also can be fixed on the vehicle body) on the outer wall at U-shaped.
The height of this steering column of motor vehicle assembly and angle adjusting mechanism comprise steering shaft, steering shaft sleeve pipe, upward tubing string, slip cap, lower tubular column, articulated stand, adjusting support, U-shaped permanent seat, U-shaped are regulated bracket component, release handle etc.Wherein steering shaft and steering shaft sleeve pipe connect by the free-sliding spline duplicate invoice, and the two is separately fixed in the upper and lower tube column by antifriction-bearing box.Articulated stand and U-shaped permanent seat can be welded on the lower tubular column, and release handle and U-shaped are regulated support and be installed on the U-shaped permanent seat by connecting screw rod.Between lower tubular column and the last tubing string slip cap is arranged, lower tubular column one end has axial long rabbet, and slip cap also has the axial pass trough mouth of width unanimity.When release handle unclamped, each part was under the free state, had the radial fit gap between tubing string, and last tubing string can be free to slide in slip cap vertically, thereby reached the function of axial adjustment.Under the locking state, the notch of lower tubular column and slip cap narrows simultaneously, and diameter clearance is eliminated, and last tubing string promptly is fixed in the slip cap and can not moves freely.Having to rotate initial point on the U-shaped adjusting support is the deep-slotted chip breaker in the center of circle, and after release handle, connecting screw rod and end face adjusting cam can slide in deep-slotted chip breaker, thereby reach the function that steering column assembly carries out angular adjustment, adjusts the back locking release handle that finishes.
The regulatory function of this steering column of motor vehicle assembly height and angle mainly relies on U-shaped to regulate support, release handle and last tubing string, endwisely slipping of lower tubular column and realizes, the scope that bearing circle can be regulated is big, the chaufeur of different statures can both pass through Steering gear height and angular adjustment, finds the steering position of the most comfortable.
Safe energy absorber is that last tubing string, lower tubular column overcome and make axial compression after clamping confining force, the effect that buffering stand, injection moulding are inserted in addition, articulated stand, mount pin (mounting sleeve) also have collision energy-absorbing.When serious collision takes place in automobile, last tubing string is along the downward slippage of lower tubular column, plastic pin during injection moulding is inserted is cut off the disengaging support, self deforms buffering stand, mount pin breaks away from spacing along the slippage of articulated stand chute, make to go up tubing string, lower tubular column integral body moves down, thereby absorb vehicle effectively owing to being subjected to external force collision to be passed to impact kinetic energy on tubing string, the lower tubular column.
Advantage of the present utility model: this utility model is simple in structure, makes easily, under the prerequisite of guaranteeing the properties of product quality, can enhance productivity, and is easier to suitability for industrialized production.In addition, also have safe energy absorption device,, can protect chaufeur to avoid the life danger that causes because of external force collision by actv. in case vehicle collision accident takes place.
