Apparatus for simulating driving a land vehicle

1 . Apparatus for simulating driving a land vehicle, comprising:

a base provided with a flat support surface on which a mobile platform is positioned,

first means for moving said mobile platform along two linear directions perpendicular to each other (X, Y) and for rotating said mobile platform along a third direction, or axis, that is perpendicular to a plane that contains the X, Y, directions, wherein said first movement means comprise a plurality of cables connected with a first portion thereof to the mobile platform and with a second portion thereof to respective actuation members, which are able to determine a movement of the mobile platform with respect to the base,

a driving position associated with said mobile platform, and

second means for moving said one driving position with respect to the mobile platform, comprising a plurality of linear connection elements, each associated with a respective first end to the mobile platform, and with a respective second end, opposite the first end, directly or indirectly to the driving position,

wherein each of said first ends is pivoted with a base joint to a corresponding sliding block, the sliding block slidingly associated with a rectilinear guide, and each of said second ends is pivoted to the driving position with a butt or cardanic joint, said sliding block and said guide defining another base joint, wherein said second means allow a movement of said driving position according to further three directions (x, y and z), and a rotation around the same three directions (x, y and z), and

wherein said mobile platform is provided with a hollow connection body open at least at a top part to which said cables connect, and in that said guides are disposed at an incline with respect to the support surface inside said connection body, each guide being stably connected on one side to an upper part of said connection body and on an opposite side to a bottom wall of said connection body.

2 . The apparatus of claim 1 , wherein said base joint is of the universal a universal type and said butt or cardanic joint is of a spherical type.

3 . The apparatus of claim 1 , wherein said base joint comprises two rotoidal joints with intersecting axes of rotation, and said butt joint is of a spherical type.

4 . The apparatus of claim 1 , wherein said second movement means comprise a plurality of said guides, in a number coordinated with that of said connection elements.

5 . The apparatus of claim 1 , wherein said second movement means comprise a plurality of said guides in a number smaller than the number of said connection elements.

6 . The apparatus of claim 1 , wherein said second movement means comprise six connection elements.

7 . The apparatus of claim 1 , wherein said second movement means has at least a configuration symmetrical with respect to a vertical median plane of said mobile platform, and wherein said guides are parallel to each other.

8 . The apparatus of claim 1 , wherein said second movement means has at least one radial symmetry configuration with respect to a central vertical axis of said mobile platform, and wherein said guides converge toward a central point of said mobile platform.

9 . The apparatus of claim 8 , wherein said guides are grouped into pairs, wherein at least the guides of each pair are parallel to each other.

10 . The apparatus of claim 1 , wherein said guides are attached to a support plane of said mobile platform which is parallel to said support surface.

11 . The apparatus of claim 1 , wherein said guides are attached to support planes of said mobile platform which are inclined with respect to said support surface.

12 . The apparatus of claim 1 , wherein said connection elements have a fixed length.

13 . The apparatus of claim 1 , wherein the mobile platform is provided with a plurality of emitter-receiver devices positioned so as to emit a forward signal against an edge delimiting the support surface and receive a correlated return signal.

14 . The apparatus of claim 1 , further comprising a compensation unit comprising balancing masses mobile on respective sliding guides by means of respective actuation members and attached to the mobile platform.
