Patent

CA 2218304

In an engine for a vehicle including a bearing cap integral type oil pan which has a plurality of bearing cap sections integrally provided thereon and which is integrally coupled to a cylinder block, connecting bolts are screwed into the bearing cap sections from the cylinder block to integrally couple the cylinder block and the oil pan to each other. An oil pan chamber, which is an as-cast bore made by drawing a die in an axial direction of a crankshaft, is defined to extend continuously in the axial direction of a crankshaft between the bearing cap sections and bottom wall of the oil pan. Thus, the oil pan can be produced simply, at a low cost, by a casting process and moreover, it is possible to reduce the weight and size of the oil pan and increase the rigidity of the oil pan.

Moteur de véhicule comprenant un carter d'huile à chapeau de palier intégré présentant une pluralité de sections de chapeau de palier intégré, assemblé au bloc-cylindres; des boulons d'assemblage sont vissés dans les sections de chapeau de palier à partir du bloc-cylindres afin d'assembler intégralement le bloc-cylindres et le carter d'huile. Une chambre de carter d'huile, qui est un alésage venu de fonderie réalisé par passage d'une matrice dans la direction axiale du vilebrequin, est définie de manière à se prolonger en continu dans la direction axiale du vilebrequin entre les sections de chapeau de palier et la paroi inférieure du carter d'huile. Ainsi, le carter d'huile peut être fabriqué simplement, à faible coût, par coulage; de plus, il est possible de réduire le poids et l'encombrement du carter d'huile et d'accroître la rigidité de ce dernier.
