Abstract
The invention relates to a cylindrical elastomeric bearing with wide angular deflection comprising three cylindrical elements: a central element (1) and two lateral elements (2, 3) arranged either side of the central element (1). Each torsible cylindrical element is made up of a deformable elastomeric central part, relatively flexible angularly and relatively rigid radially, which is rigidly locked to an inner armature and to an outer armature; the outer armature (6) of the central element (1) and the inner armature (8, 11) of each lateral element (2, 3) are rigidly locked together so as to form a single part, the common armature (13). The inner armature (5) of the central element (1) is mounted on an inner sleeve (14) to which it is rigidly locked, and the outer armature (9, 12) of each lateral element (2, 3) is mounted in an outer sleeve (15) to which it is rigidly locked; inner sleeve (14) and outer sleeve (15) are coaxially arranged in such a way that the outer sleeve (15) and the inner sleeve (14) can rotate in relation to each other about their common axis with virtually no possibility of radial deflection.
