Abstract
The motor support (16) comprises an inner ring (20) able to receive an element of the motor and an outer ring (22) able to be fastened to a housing, and a means (24) of decoupling between the two coaxial rings (20; 22) comprising a plurality of pads (46) of elastomer material that are interposed between the inner ring (20) and the outer ring (22). Each pad (46) is substantially “H”-shaped in form. The two arms (46int, 46ext; 461, 462) of the «H» are separated by a distance B. Each arm (46int, 46ext; 461, 462) has a width D measured in the radial direction. The web (46a) of the “H” has a width A measured in the orthoradial direction. The ratio A/B B is greater than or equal to 1.4, and the ratio A/D is greater than or equal to 2.
