Abstract
A car having: two front wheels; two rear wheels; a body, which has two front wheel compartments, each housing, on the inside, a corresponding front wheel, and two rear wheel compartments, each housing, on the inside, a corresponding rear wheel; and two covering panels, each arranged in the area of a corresponding wheel compartment to close the wheel compartment. Each covering panel is mounted on the body so as to be movable between a contracted position, in which the covering panel is completely flush with the body, and an expanded position, in which the covering panel is at least partially spaced apart from the body. Two actuator devices are provided, each coupled to a corresponding covering panel so as to move the covering panel between the contracted position and the expanded position.
Claims19
A car (1) comprising:
- two front wheels (2);
- two rear wheels (3);
- a body (4), which has two front wheel compartments (5), each of which houses, on the inside, a corresponding front wheel (2), and two rear wheel compartments (6), each of which houses, on the inside, a corresponding rear wheel (3);
- at least two covering panels (7, 8), each arranged in the area of a corresponding wheel compartment (5, 6) to close the wheel compartment (5, 6) and is mounted on the body (4) so as to be movable between a contracted position, in which the covering panel (7, 8) is completely flush with the body (4), and an expanded position, in which the covering panel (7, 8) is at least partially spaced apart from the body (4);
- two actuator devices (9), each coupled to a corresponding covering panel (7, 8) so as to move the covering panel (7, 8) between the contracted position and the expanded position;
- and
- a control unit (10) configured to detect a steering angle of the corresponding wheels (2, 3) and to move the covering panels (7, 8) between the contracted position and the expanded position depending on the steering angle of the corresponding wheels (2, 3);
- wherein each actuator device (9) is a pneumatic device and comprises:
- a deformable body (11), which expands, increasing its size, when it is subjected to the atmospheric pressure and contracts, reducing its size, when it is subjected to a vacuum;
- a vacuum source (12), which is designed to generate a vacuum;
- and
- a pneumatic selector (13), which is designed to alternatively connect the deformable body (11) to the vacuum source (12) or the atmospheric pressure,
- wherein the control unit (10) is configured to move the covering panels (7, 8) from the contracted position to the expanded position when the steering angle of the corresponding wheels (2, 3) exceeds a first threshold value and to move the covering panels (7, 8) from the expanded position to the contracted position when the steering angle (2, 3) is smaller than the first threshold value.
