Abstract: A bump stop device comprises a bearing 20 provided with two bottom 22 and top 24 metal washers between which rolling bodies 26 are arranged. A friction ring 34 is fixed to the first of the bottom and top metal washers and rubs against the other metal washer in order to create a static frictional torque that is greater than that of the rolling bodies and, in practice, greater than 1 Nm. The friction ring 34 makes it possible to generate a controlled resisting torque that limits the transmission to the steering column of the torque generated when driving the vehicle on a convex road.

Abstract: A radial angular-contact ball bearing comprises two annular raceways with balls 24 placed between them, the centres of which are distributed around a pitch circle of the bearing, the points of contact between the balls and the two raceways being distributed on a contact cone. A cage holds the balls and comprises a plurality of cavities 32 for housing the balls. Each cavity comprises two opposing concave walls 36A, 36B forming spherical caps with a radius R, the centres 40A, 40B of the two caps being in the same radial plane at a distance from one another along an axis 42 that is tilted in relation to the axis of rotation of the bearing. The oblong shape of the cavities reduces the friction between them and the balls.

Abstract: A drive mechanism mounted on a frame (10) equipped with a body (16) containing at least one inner bearing race (24) defining an axis of rotation (26), comprises a single-piece drum (48) located entirely on a first side of a radial plane of reference (34). This drum is equipped with a tread (50) that can cooperate with a drive belt, an opening in which the body is inserted, and at least one outer bearing race (54) located opposite the inner bearing race (24). A shaft (30) solidly attached to a turning element (36) extending on a second side of the geometrical plane of reference, passes through the body and is fixed to the drum by linking means (40), which extend radially between the shaft and the drum, and are tangential to a geometrical plane (62) which is perpendicular to the axis of rotation (26) and is located at a greater distance from the transversal plane of reference than the bearing races.

Abstract: A unit consisting of a bearing equipped with a data sensor device and a housing in which the bearing is coupled. The bearing consists of an inner turning collar designed to be attached to a turning body, an outer fixed collar coupled to the housing, and rolling bodies positioned between them. The data sensor device consists of a coder that generates magnetic impulses attached to the turning collar and, attached to the fixed collar, a sensor equipped with at least two sensitive components capable of detecting such impulses. The housing is designed to permit said bearing to be locked radially and to lock the bearing axially in one direction. The unit further consists of a coupling piece for the bearing inside the housing configured such that the bearing is locked at least in the other direction.

Abstract: Roller bearing (1) equipped with an information sensor device, containing a rotating internal ring (3), a fixed external ring (2) and roller bodies (4) arranged between them, in which said information sensor device contains an encoder (10) and a sensor (11), said roller bearing (1) containing an assembly casing (22) of sensor (11) with the fixed ring (2), said casing (22) containing a cylindrical support (23) that extends over the entire axial length of the external transversal faces of sensor (11) and external ring (2), and means of axial holding (26, 27) arranged on both sides of said support (23), said means (26, 27) being supported on at least one part of the front and rear lateral faces (28, 29) of sensor (11) and external ring (2).
