Abstract
Abstract A support bearing of a rotary shaft, of the type comprising an inner ring (12) and an outer ring (10) coaxial with one another and elastic connecting strips (14a, 14b) between the two rings. The connecting strips comprise a series of first elastic strips (14a) which connect a first edge (10a) of the outer ring (10) to an axially opposite first edge (12a) of the inner ring (12), in such a way that the mid-plane of each of the first strips (14a) forms a first angle (A) with the axis (X--X) common to the two rings, and a series of second elastic strips (14b) which connect the second edge (10b) of the outer ring (10) to the second edge (12b) of the inner ring (12), in such a way that the mid-plane of each of the second strips forms a second angle (B) with the common axis (X--X). The invention is used particularly for supporting a motor-vehicle transmission shaft.
