Abstract
The invention proposes a hydroelastic support (10) intended to be interposed between two assemblies to be suspended one with regards to the other, of the type comprising two armatures (12, 14) joined together by a block of elastomer material (16), a working chamber (26) and an expansion chamber (33), connected together by a communication passage (34), and of the type in which the working chamber (26) is delimited in part by a movable diaphragm (30) whose external face (42) comprises a push-rod (44) with which there cooperates a device of the connecting-rod (50) and crank (62, 66) type for driving the movable diaphragm, in which the small end (54) of the connecting-rod (50) is connected to the push-rod (44) and in which the shaft (66) for driving the crank (62) in rotation is mounted so as to turn in a bearing (70) fixed to one (12) of the two armatures.
