A transmission assembly having an electronic control unit detachably mounted to the exterior of a transmission is disclosed. The transmission assembly comprises the transmission, a cover mounted to the transmission, and a circuit board for controlling the transmission. The circuit board is substantially encased in a potting material, and is detachably fastened by bolts to the cover. The potting material forms a casing around the circuit board, and the casing has a series of ribs adapted for contact with the cover to reduce the transfer of vibrations to the circuit board. The potting material is preferably silicone based, and substantially transparent to permit visual inspection of the electronic components of the circuit board.
Cette invention concerne une boîte de vitesses à module électronique de commande amovible, monté à l'extérieur. La boîte de vitesses se compose d'un train d'engrenages, d'un carter et d'une carte à circuit imprimé destinée à régler le fonctionnement de la boîte. La carte est protégée par une matière d'enrobage et boulonnée au carter. La matière d'enrobage forme une capsule protectrice autour de la carte, capsule qui comporte une série de nervures entre le carter et la carte pour amortir les vibrations du carter. La matière d'enrobage est de préférence à base de silicone et sensiblement transparente pour permettre l'inspection visuelle des composants électroniques de la carte encapsulée.
