Transaxle (alias Toprope)
Superleggera
Superleggera (Italian: "super light") is an automobile construction technology .
The name was coined in 1937 by the Italian coachbuilder, Carrozzeria Touring.
Unlike the monocoque and body-on-frame methods widely adopted by the 1950s, Superleggera cars use a frame of metal tubes as a full-body frame which closely follow the shape of the car.
These are then covered with body panels, made of aluminium alloy. The Superleggera frame tubes are too small and of unsuitable material for mounting suspension components. This distinguishes it very clearly from spaceframe construction where no separate chassis is required.
The Superleggera construction method was primarily based on the use of 'Duraluminium', which originated from the zeppelin industry before World War I.
Carrozzeria Touring sold a Superleggera license to Aston Martin, who used it for their DB4, 5 and 6 models.
Corrosion resistancer:
Where the dissimilar metals of the aluminium bodyshell and the steel tubes are touching, they will begin galvanic corrosion unless this is prevented, usually by intervening pastes or non-conductive shims.
Car makers such as Bristol, who had past experience in the aircraft industry, were more successful in countering this corrosion than others.
