Abstract

A high-performance sports car having: a chassis; a bottom facing a ground; four wheels; four suspensions, each of which connects a corresponding wheel to the chassis, has a variable geometry, and is equipped with at least one actuator device adapted to modify the geometry of the suspensions; and a body which covers the chassis and is equipped with four wheel arches, each of which surrounds a corresponding wheel at the top. The chassis is provided inferiorly with a plurality of support feet which are adapted to rest on the ground to support the weight of the sports car. The actuator devices are configured to lift, only when the sports car is parked, the wheels upwards with respect to the chassis changing the geometry of the suspensions up to rest on the ground the support feet.

First claim

The invention claimed is:

1. A high-performance sports car ( 1 ) comprising: a chassis ( 2 ); a bottom ( 15 ) facing a ground ( 16 ) on which the sports car ( 1 ) moves; two front steering wheels ( 3 ) supported by the chassis ( 2 ) and arranged in a front position; two rear wheels ( 3 ) supported by the chassis ( 2 ) and arranged in a rear position at a certain distance from the front wheels ( 3 ); an engine which transmits the motion to driving wheels ( 3 ); a passenger compartment ( 5 ) present between the front wheels ( 3 ) and the rear wheels ( 3 ); a steering wheel which is arranged in the passenger compartment ( 5 ) and adjusts a steering angle of the two front steering wheels ( 3 ); four suspensions ( 13 ), each of which connects a corresponding wheel ( 3 ) to the chassis ( 2 ), has a variable geometry, and is equipped with at least a first actuator device ( 14 ) adapted to modify the geometry of the suspensions ( 13 ); and a body ( 4 ) which covers the chassis ( 2 ) and is equipped with four wheel arches ( 8 ), each of which surrounds a corresponding wheel ( 3 ) at the top; wherein the chassis ( 2 ) is provided inferiorly with a plurality of support feet ( 17 ) which are adapted to rest on the ground ( 16 ) to support the weight of the sports car ( 1 ); wherein the first actuator devices ( 14 ) are configured to lift, only when the sports car ( 1 ) is parked, the wheels ( 3 ) upwards with respect to the chassis ( 2 ) changing the geometry of the suspensions ( 13 ) up to rest on the ground ( 16 ) the support feet ( 17 ), wherein a sensor ( 21 ) is provided which is adapted to detect a conformation of the ground ( 16 ) below the bottom ( 15 ) to check the presence of raised parts in the ground ( 16 ); and wherein a control unit ( 22 ) is provided which is configured to lift, only when the sports car ( 1 ) is parked, the wheels ( 3 ) upwards with respect to the chassis ( 2 ) only when the ground ( 16 ) below the bottom ( 15 ) has no raised parts.

2. The sports car ( 1 ) according to claim 1 , wherein the support feet ( 17 ) are movable between a driving position in which the support feet ( 17 ) are flush with the bottom ( 15 ) and a parking position in which the support feet ( 17 ) protrude downwards from the bottom ( 15 ).

3. The sports car ( 1 ) according to claim 2 and comprising a plurality of second actuator devices ( 18 ), each of which is capable of moving, only when the sports car ( 1 ) is parked, a corresponding support foot ( 17 ) between the driving position and the parking position.

4. The sports car ( 1 ) according to claim 1 , wherein the sensor ( 21 ) is of the optical type and comprises a video camera which is arranged in a recess ( 19 ) present in the bottom ( 15 ) and is oriented in a direction opposite to a forward travel direction (V) of the sports car ( 1 ).

5. The sports car ( 1 ) according to claim 4 , wherein the recess ( 19 ) is protected by a normally closed flap ( 20 ) which opens only when the sports car ( 1 ) is parked.

6. The sports car ( 1 ) according to claim 1 and comprising: at least a first movable panel ( 23 ; 26 ) which is not structural and thus is not part of the chassis ( 2 ), is arranged in correspondence with a single and sole wheel ( 3 ), and is vertically movable with respect to the chassis ( 2 ) between a lowered position which is always assumed while driving and a raised position which is assumed only when the sports car ( 1 ) is parked; and at least a third actuator device ( 24 ; 27 ) which is completely separate from and independent of the first actuator devices ( 14 ) and is adapted to move the first movable panel ( 23 ; 26 ) with respect to the chassis ( 2 ) between the lowered position and the raised position with a movement totally autonomous from a movement of the wheels ( 3 ) with respect to the chassis ( 2 ).

7. The sports car ( 1 ) according to claim 6 , wherein the first movable panel ( 23 ) is part of the body ( 4 ).

8. The sports car ( 1 ) according to claim 7 and comprising at least an elastically deformable portion ( 25 ) which connects the first movable panel ( 23 ) to the rest of the body ( 4 ) and elastically deforms to allow the first movable panel ( 23 ) moving between the lowered position and the raised position.

9. The sports car ( 1 ) according to claim 6 , wherein the first movable panel ( 26 ) is part of a wheel arch ( 8 ).

10. The sports car ( 1 ) according to claim 6 , wherein: the first movable panel ( 23 ) is part of the body ( 4 ); and at least a second movable panel ( 26 ) is provided which is part of a wheel arch ( 8 ), is arranged below the first movable panel ( 23 ), and is movable vertically and synchronized with the first movable panel ( 23 ) between a lowered position which is always assumed while driving and a raised position which is only assumed when the sports car ( 1 ) is parked.

11. A high-performance sports car ( 1 ) comprising: a chassis ( 2 ); a bottom ( 15 ) facing a ground ( 16 ) on which the sports car ( 1 ) moves; two front steering wheels ( 3 ) supported by the chassis ( 2 ) and arranged in a front position; two rear wheels ( 3 ) supported by the chassis ( 2 ) and arranged in a rear position at a certain distance from the front wheels ( 3 ); an engine that transmits the motion to driving wheels ( 3 ); a passenger compartment ( 5 ) present between the front wheels ( 3 ) and the rear wheels ( 3 ); a steering wheel which is arranged in the passenger compartment ( 5 ) and adjusts a steering angle of the two front steering wheels ( 3 ); four suspensions ( 13 ), each of which connects a corresponding wheel ( 3 ) to the chassis ( 2 ), has a variable geometry, and is equipped with at least a first actuator device ( 14 ) adapted to modify the geometry of the suspensions ( 13 ); and a body ( 4 ) which covers the chassis ( 2 ) and is equipped with four wheel arches ( 8 ), each of which surrounds a corresponding wheel ( 3 ) at the top; wherein the chassis ( 2 ) is provided inferiorly with a plurality of support feet ( 17 ) which are adapted to rest on the ground ( 16 ) to support the weight of the sports car ( 1 ); wherein the first actuator devices ( 14 ) are configured to lift, only when the sports car ( 1 ) is parked, the wheels ( 3 ) upwards with respect to the chassis ( 2 ) changing the geometry of the suspensions ( 13 ) up to rest on the ground ( 16 ) the support feet ( 17 ); wherein at least a first movable panel ( 23 ; 26 ) is provided which is not structural and thus is not part of the chassis ( 2 ), is arranged in correspondence with a single and sole wheel ( 3 ) and is vertically movable with respect to the chassis ( 2 ) between a lowered position which is always assumed while driving and a raised position which is assumed only when the sports car ( 1 ) is parked; and wherein at least a second actuator device ( 24 ; 27 ) is provided which is completely separate from and independent of the first actuator devices ( 14 ) and is adapted to move the first movable panel ( 23 ; 26 ) with respect to the chassis ( 2 ) between the lowered position and the raised position with a movement totally autonomous from a movement of the wheels ( 3 ) with respect to the chassis ( 2 ).

12. The sports car ( 1 ) according to claim 11 , wherein the first movable panel ( 23 ) is part of the body ( 4 ).

13. The sports car ( 1 ) according to claim 12 and comprising at least an elastically deformable portion ( 25 ) which connects the first movable panel ( 23 ) to the rest of the body ( 4 ) and elastically deforms to allow the first movable panel ( 23 ) moving between the lowered position and the raised position.
