Definitions
- the present invention refers to a deflector for the air-flow intended to improve the penetration index of the motor-vehicle. More in particular the invention refers to a device to separate the air-flow located under the body side ahead of the rear wheels.
- Said object is achieved by means of a device that deflects the air-flow from the rear wheels of a motor-vehicle presenting the characteristics of claim 1.
- figure 1 is a magnified perspective transparent view of the rear part of the body side of a motor vehicle, provided with the air-flow deflector according to the invention
- figure 2 is a magnified transparent top view of the device in figure 1 mounted on part of the sill
- figure 3 is a side view, from inside the motor-vehicle, of the device in figure 2.
- reference number 1 indicates the rear part of the body side of a motor-vehicle, provided with a wheelhouse 2 for the rear wheel (not shown).
- the device consists of a solid body preferably made of plastic material. Its shape is that of a boat, the preferred embodiment being symmetrical, presenting a sharp bow, bulwarks 6 of the same height, flat bottom 7 and a flat poop 8.
- the optimum width corresponds to the width of the tyre mounted on the motor-vehicle.
- the device is connected to the sill, in a known way, with the bow 5 towards the front part of the motor-vehicle, the bulwark corresponding to the inside edge of the wheel and the poop 8 corresponding to the opening of the wheelhouse.
- the embodiment shown in figures 1 and 3 presents an asymmetrical shape in order to better fit the shape of the motor-vehicle and to be more pleasant from the esthetical point of view, even if part of the effectiveness of the symmetrical shape is lost. It therefore presents a body side that narrows towards the poop and a curved bottom with the bow higher than the central part of the hull. Besides, it is narrower than the width of the tyre and its internal bulwark is located edge-wise with the internal edge of said tyre.
- the dimensions of the device will be proportional to the dimensions of the motor-vehicle, being the width basically the same as the width of the tyre.
- the device can be mass forged with an applied - not structural - sill, or can be applied, detachable in the case of a structural sill and/or in case of presence of hooks of the
- Webb type couplings to lift the motor-vehicle, holes or elements of any kind that can modify the geometry between the sill and the device itself.
