Background technology
Steering gear is the element of hydrostatic steering system closure dish and deflector.By Steering gear, chaufeur passes to deflector to moment of torsion, and the drive deflector is transported to pump fuel feed and turns to oil cylinder, realizes fluid-link steering.Be equipped with anti-joyride device on the existing steering column for vehicles, utility model as notification number CN2450027Y, announced a kind of anti-theft device for vehicle, be characterized in that lock body is to link into an integrated entity with steering-column tube, have steering column aperture at steering-column tube and dead bolt relative position, on steering shaft, have and the corresponding axial trough that turns to of dead bolt.This constitutes a kind of built-in lock structure, externally can't open it with instrument, and steering shaft can't take off.But turning to axial trough to open on steering shaft, be used for cooperating the realization locking with dead bolt, the structural strength of steering shaft can reduce like this, and turning to axial trough is blind groove, and it is bigger to turn to axial trough and dead bolt to be engaged in the rolling momentum like this, may cause moment to load.Also there is employing on steering shaft, to adorn latch, the groove of unblanking on the latch, be used to cooperate the structure of the lock tooth realization anti-theft feature on the ignition lock, though solved the strength problem of steering shaft like this, but the locked groove that this structure is opened is blind groove, the latch structural strength is not high, and ignition lock rocks and may cause moment to load.In the national standard, to turning to the antitheft special requirement that has, be welded on mode on the steering shaft, under the moment of torsion of 300Nm, must not destroy, and locked groove be blind groove, when turning to antitheft authentication, can not carry the moment of torsion of 300Nm for latch.
Summary of the invention
The purpose of this utility model is to solve that existing Steering gear theft-prevention structure intensity is not high, ignition lock rocks the problem that may cause moment to load and can not carry the 300Nm moment of torsion when turning to antitheft authentication, a kind of Steering gear burglar-proof mechanism is provided, its structural strength height, rolling momentum when having reduced loading moment, avoid can not the loading moment situation because of rocking of ignition lock generation, can carry the 300Nm moment of torsion preferably.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of Steering gear burglar-proof mechanism, comprise steering shaft, latch, steering-column tube and be fixed on ignition lock on the steering-column tube, ignition lock is provided with the lock tooth, described latch is placed on the steering shaft, and it is fixing with the steering shaft welding, be arranged with the locked groove that lock tooth a pair of and on the ignition lock matches on the lateral surface of described latch, described locked groove is a groove.Steering shaft is a castellated shaft, it is cylindric that latch is, latch is placed on the steering shaft, cover is loaded onto steering-column tube outside then, fixed ignition switch on the steering-column tube, latch and steering shaft welding are fixing, and fixation is easy to process, locked groove is made as groove, increased the structural strength of latch like this, after locked groove was made as groove, it is darker that the lock tooth inserts, more firm ordinatedly with locked groove, rolling momentum when having reduced loading moment, avoid can not the loading moment situation because of rocking of ignition lock generation, can carry the 300Nm moment of torsion preferably.
As preferably, described lock tooth is Long Circle, the described locked groove Long Circle groove that to be shape match with the lock tooth.Lock tooth, locked groove are Long Circle, and bearing surface increases like this, and intensity is better, has reduced the risk of skidding when loading moment and can not load.
As preferably, the medial surface of described latch is the interior hexagon that shape and steering shaft external surface shape match.The structure that latch is inner such can more firmly cooperate with steering shaft.
As preferably, steering-column tube is provided with the inserting hole that the lock tooth be convenient on the ignition lock passes through, and the inserting hole shape matches with the lock odontoid.The setting of inserting hole is convenient to lock interting of tooth, and the inserting hole shape matches with the lock odontoid, after locking tooth like this and locked groove cooperating, can guarantee better to lock the stability that tooth cooperates with locked groove, has reduced the risk of skidding when loading moment and can not load.
As preferably, described Steering gear burglar-proof mechanism also comprises the ignition lock pressing plate, ignition lock pressing plate semicircular in shape, the two ends of ignition lock pressing plate have through hole, have the fixed part that matches with the ignition lock pressing plate on the ignition lock, the medial surface semicircular in shape of described fixed part, the lock tooth is positioned at the middle part of fixed part medial surface, the two ends of fixed part have screw, the fixed part of bolted connection ignition lock pressing plate and ignition lock.The assembling of ignition lock is convenient in the setting of ignition lock pressing plate, the ignition lock pressing plate can be connected with the fixed part of ignition lock by bolt, thereby ignition lock is fixed on the steering-column tube, and assembling is simple, convenient disassembly.
The beneficial effects of the utility model are: locked groove is a groove, increased the structural strength of latch like this, after locked groove is made as groove, it is darker that the lock tooth inserts, more firm ordinatedly with locked groove, rolling momentum when having reduced loading moment, avoid can not the loading moment situation because of rocking of ignition lock generation, can carry the 300Nm moment of torsion preferably.
