Description
Technical field
The utility model relates to a kind of automobile steering system, and more specifically, it relates to a kind of automobile and turns to mandrel locking theft-prevention structure.
Background technology
At present, automobile all can arrange turning device's lock locking apparatus, to reach certain antitheft object. The moment of torsion of the 300N.M that locking means applies under should be able to bearing static conditions on two directions of steering shaft. Now conventional turning device's ata form is turning to turning to of tubing string inside to weld lock sleeve on mandrel, turn to simultaneously and tubing string is offered lock only mouth, after extracting key, dead bolt ejects, steering wheel rotation, just can make dead bolt pass turn to lock on tubing string only mouth stretch into carry out in lock sleeve locking only spacing. After key insertion starts automobile, dead bolt reclaims, and from lock sleeve, only mouth moves out with locking, and unlocks. Due to the restriction turning to tubing string lock stop bit to put, dead bolt stretches into the length only 2-3mm turning to lock sleeve on mandrel, shorter lock stops length and is difficult to bear bigger moment of torsion, as long as firmly rotating of steering wheel still can be got up by twisting, does not play real anti-theft function. And many times, after automobile flameout, driver's mishandle have rotated bearing circle makes dead bolt lock spline to mandrel, in insertion key start-up course, the phenomenon that key cannot rotate easily occurs, have impact on the normal startup of automobile.
Chinese patent notification number CN202208305U, disclose the car steering tube column of a kind of novel anti-theft structure, by turning to, axle assembly, post pipe assembly and underdrive axle assembly are formed for it, axle assembly is turned to be made up of steering shaft, pintle hook lock and precision positioning ring, precision positioning ring interference is fitted in steering shaft, being set with pintle hook lock on precision positioning ring, outside surface one end of pintle hook lock is manufactured with lock groove. Precision positioning ring force fit is adopted to be connected between steering shaft with pintle hook lock, can eliminate and weld the pollution on environment and impact, it is convenient to reclaim after product to life cycle, but only reliability is not good for lock, as long as firmly rotating of steering wheel still can be got up by twisting, lock inserts key and starts in automobile process after stopping, the phenomenon that key cannot rotate easily occur, have impact on the normal startup of automobile.
Practical novel content
The utility model overcomes existing steering lock mechanism lock, and only reliability is not good, as long as firmly rotating of steering wheel still can be got up by twisting, lock inserts key and starts in automobile process after stopping, the phenomenon that key cannot rotate easily occurs, have impact on the deficiency of the normal startup of automobile, provide a kind of automobile and turn to mandrel locking theft-prevention structure, lock is distance only, lock is antitheft good reliability only, the moment of torsion of 300N.M can be born completely, and lock and insert in key startup automobile process after only, dead bolt can bounce back smoothly, there will not be the phenomenon that key cannot rotate, ensure that the normal startup of automobile.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of automobile turns to mandrel locking theft-prevention structure, comprise and turn to tubing string, be arranged on to turn to and turn to mandrel in tubing string, turn to and tubing string is connected with ignition trigger mechanism, ignition trigger mechanism is provided with dead bolt, turn to and tubing string is provided with a jack with dead bolt correspondence, mandrel and jack correspondence position is turned to be hollow tubular structures, turn to mandrel and jack corresponding one circle sidewall on be laid with some locking holes, dead bolt can inject jack, locking hole realize the locking turning to mandrel is antitheft.
After automobile flameout, extract car key, dead bolt ejects, and in dead bolt front end insertion jack, now jack is not necessarily directed at locking hole, in the process that bearing circle rotates within the scope of 90 degree, after a certain locking hole is directed at jack, dead bolt insertion locking hole, it is achieved turn to mandrel and turn to the locking between tubing string, bearing circle cannot be rotated again, reach the object that locking is antitheft. Owing to turning to mandrel and jack correspondence position to be hollow tubular structures, dead bolt insertion is made to turn to the degree of depth of mandrel can reach more than 6mm, considerably increase the torque resistant intensity of dead bolt, the excessive phenomenon causing theft-prevention structure that damage occurs of moment of torsion can be prevented well, substantially increase anti-theft effect simultaneously. And turn to processing that mandrel decreases lock sleeve component with welding, be conducive to reducing costs, it is to increase production efficiency. Turning to mandrel and jack correspondence position to be hollow tubular structures, the contact area of dead bolt and locking hole sidewall is little, starts in automobile process at insertion key, and dead bolt can bounce back smoothly, there will not be the phenomenon that key cannot rotate. Automobile turns to the lock only distance of mandrel locking theft-prevention structure, lock is antitheft good reliability only, the moment of torsion of 300N.M can be born completely, and lock and insert in key startup automobile process after only, dead bolt can bounce back smoothly, the phenomenon that there will not be key to rotate, ensure that the normal startup of automobile.
As preferably, turning to the mandrel section of comprising axle and hypomere axle, upper section axle comprises and connects section and locking section, and locking section is hollow tubular structures, and the locking section diameter of the equal section of the being less than axle of the connection section diameter of upper section axle and hypomere shaft diameter, locking hole is arranged on locks in section. The locking section diameter of hollow tubular is big, increases the lock only distance of dead bolt, it is to increase lock is anti-theft effect only. Connect the installation connection that section is convenient to bearing circle.
As preferably, coupling end section is hollow tubular structures, connect section and locking section one-body molded, upper section axle and hypomere axle are one-body molded. Integrated turn to core shaft structure intensity good, it may also be useful to the life-span is long.
Another kind of scheme, connection section is hollow tubular structures, connect section and locking section one-body molded, spline joint between the locking section of upper section axle and hypomere axle. Upper section between axle and hypomere axle by spline joint, connect reliable, be convenient to turn to the processing of mandrel simultaneously.
The third scheme, connection section is solid shaft, spline joint between the locking section of upper section axle and hypomere axle, connects section and is plugged on locking section end and welds together with locking section. Solid shaft structural strength is good, and the mode of connection strength of joint of welding is good.
As preferably, dead bolt is obliquely installed from outer upward toward interior. Lock and it is obliquely installed, be convenient to eject and retraction.
Compared with prior art, the beneficial effects of the utility model are: (1) automobile turns to the lock only distance of mandrel locking theft-prevention structure, and lock is antitheft good reliability only, can bear the moment of torsion of 300N.M completely;(2) lock inserts after stopping in key startup automobile process, and dead bolt can bounce back smoothly, the phenomenon that there will not be key to rotate, and ensure that the normal startup of automobile.
