Abstract

The utility model discloses a dismountable automobile steering wheel. The dismountable automobile steering wheel is characterized in that the steering wheel is arranged at a steering gear shaft by a panel heart sliding sleeve, and the steering wheel can rotate in the circle direction at the steering gear shaft. The steering gear shaft is provided with a neck circular groove. The groove is matched with a detachable type spring clamp to axially lock the steering wheel to the steering gear shaft. The automotive automobile steering wheel can be conveniently disassembled and assembled by matching the spring clamp and the groove. The automotive automobile unladed the steering wheel has the antitheft function. The utility model not only provides a new antitheft form to the automotive automobile, but also provides a dismountable structural form to the repair of the steering wheel.

Description

The detouchable motor vehicle steering wheel

Technical field:

The utility model relates to the bearing circle in the power actuated vehicle steering swivel system.

Background technology:

Antitheft at power actuated vehicle, the existing variety of way that adopts of people comprises burglar alarm being set, anti-theft column lock or the like being set that various mode has different advantages, but also exists different problems simultaneously.

Bearing circle is the necessary member of power actuated vehicle, does not have the power actuated vehicle of bearing circle to be driven away.At present, motor vehicle steering wheel all is the version that fixedly installs, and the bearing circle that relies on clamp nut will be fixed on the steering shaft is locked.This version must use special tool could implement dismounting, keeps in repair also very complicated and inconvenient.

Summary of the invention:

The utility model provides a kind of detouchable motor vehicle steering wheel, and based on this detouchable bearing circle, the antitheft mode that self-propelled vehicle is new is when the car owner leaves vehicle, and with bearing circle dismounting, self-propelled vehicle that can not the installation direction dish has promptly possessed anti-theft feature.

The technical scheme that the utility model technical solution problem is adopted is:

Constructional feature of the present utility model to be bearing circle slide over its dish core can be with on its steering shaft that rotates in a circumferential direction, described steering shaft is provided with the neck annular slot, is equipped with in the annular slot steering wheel shaft to the removable jew spring clamp plate that is locked on the steering shaft.

In needs,, can be easily the bearing circle of power actuated vehicle be carried out dismounting by cooperating between spring clamp plate and the annular slot.The power actuated vehicle that unloads bearing circle has promptly had anti-theft feature.The utility model not only provides a kind of new antitheft form for power actuated vehicle, and simultaneously, its removable version also is very easy to the maintenance to bearing circle.

The drawing explanation:

Fig. 1 is the utility model sectional structure scheme drawing.

Fig. 2 is the utility model plan structure scheme drawing.

Number in the figure: hole, 6 bolt of rear end plates, 7 dead bolts, 8 axial push rods, 9 steering column jackets, 10 back-up rings, 11 bearings, 12 jump rings, 13 annular slots are pulled out in 1 bearing circle, 2 steering shafts, 3 spring clamp plates, 4 extension springs, 5.

The specific embodiment:

Referring to accompanying drawing 1, bearing circle 1 slides over its dish core can be with on its steering shaft that rotates in a circumferential direction 2, steering shaft 2 is provided with neck annular slot 13, is equipped with in the annular slot 13 bearing circle 1 axial lock is fixed on removable jew spring clamp plate 3 on the steering shaft 2.

Referring to Fig. 2, in the present embodiment, two settings about spring clamp plate 3 is, two clamp one ends are fixed on the bearing circle 1, the other end connects with extension spring 4, pull out hole 5 be opened in two relative sides of clamp side on.Shown in the figure, two clamps are symmetrically formed the dish shape, its fixed end is to position on bearing circle 1 with bolt of rear end plate 6, two clamps can " opening " under the external force effect that has overcome extension spring 4 elastic force, clamp after " opening " can break away from from annular slot 13, so bearing circle 1 just owing to removed axial locking, can directly unload from steering shaft 2.

As shown in Figure 1, the axial push rod 8 with dead bolt 7 interlocks is set in the present embodiment, axially the top of push rod 8 is pointed to and is pulled out hole 5, and has to insert and pull out hole 5 and make spring clamp plate 3 break away from the wedge shape end face of annular slots 13.

In order to realize and the interlock of lock, on Vehicle lock structure, should adopt many gears lock, comprise starting gear, preheating gear, flame-out gear, locking gear etc., the gear of the required use of the utility model can independently be set.In concrete the enforcement, axially push rod 8 cooperates with the inclined-plane of inclined-plane with dead bolt 7 in its bottom, and dead bolt hole is disposed radially in steering shaft 2 and steering column jacket 9.The push rod groove is set, and this push rod groove is along the axial setting of steering shaft 2, and runs through the dish core of bearing circle 1.Axially push rod 8 places the push rod groove, is fixed in the push rod groove by back-up ring 10, bearing 11 and jump ring 12, can only pass down vertically to guarantee push rod 8.

Figure 1 shows that unlocking condition, at this moment, dead bolt 7 withdraws from, and axially push rod 8 returns are in the bottom of push rod groove, and spring clamp plate 3 fixes in the neck annular slot 13 of steering shaft 2, and bearing circle 1 is axially being locked, and can drop into normal use.

When needing disassembly direction dish 1, at first rotate car key on the cooresponding gear of tapered end, so, the dead bolt 7 of lock inserts in the dead bolt hole, inclined-plane with dead bolt 7 upwards promotes axial push rod 8, and axially the top rod end of push rod 8 inserts and pulls out in the hole 5, and two clamps are stirred to both sides, break away from annular slot 13 until spring clamp plate 3, bearing circle 1 can directly take off from steering shaft 2.

During installation, at first need to open lock, withdraw from dead bolt 7 with key, only under this state, axial push rod 8 restorable below the compressing of spring clamp plate 3.If do not open lock, dead bolt 7 fails to withdraw from, and axially push rod 8 can't return, just bearing circle 1 also can't be installed, so realizes " antitheft ".
