Anti-theft locking means for a vehicle steering shaft |
摘要 |
An anti-theft locking device for vehicles includes an annular locking sleeve mounted concentrically about and normally in frictional engagement with the vehicle steering shaft. The locking sleeve includes a body portion having a serpentine cross-sectional configuration, thereby defining on the inner periphery of the sleeve a plurality of alternate smooth convex projections and concave valleys. The convex projections are in frictional engagement with the circumferential surface of the steering shaft by a predetermined frictional force that is greater than the rotational torque force produced during normal steering operation of the vehicle. A plurality of circumferentially spaced teeth extend radially outwardly from the locking sleeve, thereby to define between the teeth a plurality of locking slots one of which is arranged to receive the free extremity of the locking arm of a locking device.
