Abstract: A wheel unit with a disengageable drive for an electric vehicle has a wheel pin rotatably supported within a cylindrical wall of a central opening of the a wheel hub by a first rolling bearing, arranged on a portion of the wheel pin further away from a driven member (6, and by a second rolling bearing and a third rolling bearing set alongside one another, arranged on a portion of the wheel pin closer to the driven member. The first bearing and the second bearing have respective outer rings, mounted with interference fit within the cylindrical wall and respective inner rings rigidly mounted on the wheel pin and rigidly connected together by a spacer sleeve. The third bearing has a respective outer ring mounted with possibility of axial play between the second bearing and an annular shoulder of the wheel pin.

Abstract: A braking pad for vehicles has a backplate suitable for connection to a braking member and supports, on a first face, a block of friction material; the braking pad, in addition, has a sensor provided with a detection head engaging a hole in the backplate and is retained in a reference position fixed by a plate retention member; such an element is directly coupled to the backplate via engagement portions and has an annular portion provided with an inner edge, which is coaxial to the above-mentioned hole and is coupled to the sensor detection head via friction and/or via interference coupling and/or via snap coupling.

Abstract: A motor vehicle is provided with a conveyor structure that conveys the entire flow of air that traverses the radiator downwards and then longitudinally underneath the floor panel of the motor vehicle, preventing said flow from traversing the engine compartment and obtaining a consequent reduction in the aerodynamic resistance of the motor vehicle. Associated to the aforesaid conveyor structure are active and passive fins for enabling an adequate cooling of the components of the engine unit or electronic components associated thereto during given operating conditions.
