Abstract

L'invention concerne un différentiel de transmission comportant des moyens de friction associés aux satellites et aux planétaires, caractérisé en ce que les moyens de friction du différentiel sont formés par une coquille (50) de friction qui est obtenue en reliant entre elles au moins trois des rondelles (46, 48) de friction constituant ladite coquille (50) par l'intermédiaire de moyens (60) de liaison par emboîtement élastique, lesdits moyens (60) comportant pour chaque liaison entre deux coquilles (46, 48) de friction une partie mâle (72) et une partie femelle (74) complémentaires et respectivement portées par un bras (70) de liaison.The invention relates to a transmission differential comprising friction means associated with the planets and planets, characterized in that the friction means of the differential are formed by a friction shell (50) which is obtained by interconnecting at least three friction washers (46, 48) constituting said shell (50) by means of elastic interlocking connection means (60), said means (60) comprising for each connection between two friction shells (46, 48) a male part (72) and a female part (74) complementary and respectively carried by a connecting arm (70).
