Title (EN) COOLING OF A GEARBOX
(FR) REFOIDISSEMENT D'UNE BOITE DE VITESSES
Abstract: front page image
(EN)The invention relates to a gearbox (2) for a vehicle (18), whereby the gearbox (2) comprises an at least partly double-walled gearbox housing (4) in which at least one cavity (6) is arranged between an inner wall (8,8’,8’’,8’’’) and an outer wall (10) of the gearbox housing (4), the inner wall (8,8’,8’’,8’’’) seperates oil (12) in the oil pan (14) of the gearbox (2) from the cavity (6), and coolant (16) which cools the engine (20) of the vehicle (18) flows through the cavity (6) so that the coolant (16) of the engine (20) also cools the gearbox (2).
(FR)L'invention concerne une boîte de vitesses (2) destinée à un véhicule (18). Cette boîte de vitesses (2) comprend un carter (4) ayant au moins partiellement une double paroi. Ce carter abrite au moins une cavité (6) qui est située entre une paroi interne (8, 8', 8'', 8''') et une paroi externe (10) du carter (4). La paroi interne sépare l'huile (12) du carter d'huile (14) de la boîte de vitesses (2), de la cavité (6). Le réfrigérant (16) qui refroidit le moteur (20) du véhicule (18), s'écoule par la cavité (6) de telle manière que le réfrigérant (16) refroidisse aussi la boîte de vitesses (2).
