Abstract

L'invention concerne un dispositif pour diminuer le bruit des machines à combustion interne, en particulier des moteurs de véhicules comportant un carter dans lequel le vilebrequin est monté radialement par en dessous. Selon l'invention, les brides inférieures 2 du carter de vilebrequin sont reliées, de façon connue, par des lames transversales de raidissement 6, lesdites lames 6 étant fixées, par exemple vissées à un cadre 3 ou bien faisant partie de celui-ci, et le carter inférieur ou d'huile est relié, de préférence par vulcanisation, par l'intermédiaire d'au moins un élément élastique 7 au cadre 3 des lames transversales. Application à la réduction des bruits émanant des machines à combustion interne.The invention relates to a device for reducing the noise of internal combustion machines, in particular of vehicle engines comprising a housing in which the crankshaft is mounted radially from below. According to the invention, the lower flanges 2 of the crankcase are connected, in a known manner, by transverse stiffening blades 6, said blades 6 being fixed, for example screwed to a frame 3 or else forming part of it, and the lower or oil sump is connected, preferably by vulcanization, by means of at least one elastic element 7 to the frame 3 of the transverse blades. Application to the reduction of noise emanating from internal combustion machines.
