The lock keeper intended to be mounted on the periphery (11) of a shaft (10) comprises discs (21), each pierced through with a central orifice (210) intended for receiving this shaft (10) in order to stack them on it, and is made integral in terms of rotation with this shaft (10) by means of an interlock (30) consisting of at least one projection (31)/notch (32) pair, of which one is formed in this central orifice (210) and the other is formed on the periphery (11) of this shaft (10), some of these discs (21) being equipped at their edge (211) with at least one indentation (212), these indentations (212) being intended to be aligned longitudinally so as to produce a receptacle (23) for receiving a bolt (12). The invention is used in the motor-vehicle industry.

Keeper for a lock for the rotational blocking of a shaft and its use on

A dog clutch includes complementary cooperative male and female connection parts, one of which parts is defined by a hub integral with a wheel while the other part is carried by an end part of a shaft and which have such configuration as to define a series of cylindrical peripheral bearing surfaces and to provide between two successive bearing surfaces radial abutments which define therebetween projections engaged in cavities. A centrifugal expansion device is disposed directly and at least partly in the end part so as to produce a radial expansion of the series of male bearing surfaces and normally achieve an immobilization by the effect of friction of the hub on the end part, and exceptionally achieve a locking against rotation by contact of the abutments.

Device for coupling a wheel to its shaft and the application of the

The device comprises, mounted on the steering column, a sleeve (2) in the outer surface of which are provided cavities (3) for receiving the bolt (4) of a locking system (5) for preventing rotation of the column. The sleeve is mounted on the column with a tight fit which produces the deformation of at least one of the two parts beyond the elastic limit of the material from which it is made.

A separable connecting device, in particular of a steering column for a motor vehicle, includes two shaft sections having end portions which overlap and each carrying a flange. The flanges are interconnected by connecting pins whcih are separable in the event of impact. The flanges carried by each shaft section are of identical shape, and the connecting pins are fixed to each flange and are slidably engaged in openings provided in the other flange.

Separable connecting device, in particular for the steering column of a

The double universal joint comprises two end yokes (1,2) each of which is connected by a spider element to an intermediate connecting device comprising an outer part (14) and an inner part (15) which are interconnected by an elastically yieldable element (16) interposed between the outer part and the inner part. Each of the outer and inner parts (14,15) is made from a curled and welded sheet metal blank or from a tube and includes a corresponding yoke (19,20) for connection of the part with a corresponding spider element (8,7) associated with an end yoke (1,2) of the joint.
