Title: (EN) Method of fabrication of a support for an electric motor used in motor vehicles, uses over-molding of blank to simultaneously form anti-vibration mounting and air cooling duct
(FR) PROCEDE DE FABRICATION D'UN SUPPORT DE MOTEUR ELECTRIQUE ET SUPPORT RESULTANT DE LA MISE EN OEUVRE DE CE PROCEDE
Abstract: front page image
(EN) The support has an anti-vibration coupling (18i) and a cooling air duct (14). The support is fabricated from a blank initially without the anti-vibration link and the air duct seal (15), which are both formed by molding over the blank using an elastic molding material.
(FR)

Le support comprend a) des moyens de liaison anti-vibration (18i ) et b) un canal (14) de guidage d'air de refroidissement vers le moteur. Le canal est conçu pour être raccordé à un carter d'embout du moteur à travers un joint (15) d'étanchéité. Selon l'invention, a) on fabrique une ébauche du support, dépourvue des moyens de liaison anti-vibration (18i ) et du joint d'étanchéité (15) et b) on met en place les moyens de liaison (18i ) et le joint d'étanchéité (15) lors d'une même opération de surmoulage de l'ébauche, avec un matériau élastique moulable propre à constituer à la fois les moyens de liaison (18i ) anti-vibration et le joint d'étanchéité (15).
