DEVICE IN STEERING-WHEEL LOCKS

摘要

In order to prevent breaking-up of a steering-wheel lock so as to destroy the lock by exerting a torsional moment on the steering wheel, the lock pin is made to act on a securing plate (2) which is rotatably mounted on the steering column (1) but with a powerful friction due to a friction member (3). According to the invention, a friction member (3) is fitted from either end of the securing plate (2) into spaces formed between the steering column (1) and outer conical surfaces (6) at each end of the securing plate (2). The friction members (3) are correspondingly wedge-shaped, and a wedge action is achieved by an inwards bending (4) of the two securing plate ends in a hydraulic press, the compression force applied determining the amount of frictional moment.
