Abstract: A road vehicle provided with a cooling duct for the cooling of a brake, the cooling duct including an air intake arranged at the inlet of the cooling duct, a shutter, which is mobile, so as to move between a closing position, in which the shutter closes the air intake, and an opening position, in which the shutter leaves the air intake unobstructed, and an electric actuating device, which controls the movement of the shutter and, therefore, moves the shutter between the closing position and the opening position and is mechanically configured to be normally open and, therefore, in the absence of a power supply, to push the shutter towards the opening position.

Abstract: A vehicle with movable spoilers, the vehicle having at least one spoiler movable between a minimum-angle position producing a minimum increase in vertical load, and a maximum-angle position producing a maximum increase in vertical load; and a spoiler actuating device for adjusting the position of the spoiler between the minimum-angle position and maximum-angle position as a function of the speed of the vehicle; the spoiler actuating device providing, up to a given maximum speed, for adjusting the position of the spoiler to increase the vertical load as speed increases, and for maintaining the vertical load at a substantially constant given value as long as the speed of the vehicle exceeds the maximum speed.
