Abstract

The invention concerns a vehicle oscillation device (1) comprising a sprung multipoint mounting (4) arranged between a vehicle seat (2) or driver'"'"'s cab and a base element (3) of a vehicle arranged below and suitable for rotative springing and/or damping of the vehicle seat (2) and/or driver'"'"'s cab in relation to the base element (3), wherein the sprung multipoint mounting (4) is formed of several pieces and comprises at least one fluid spring element and/or fluid damping element (5) and at least one elastomer spring element (6).

Claims

1. A vehicle oscillation device (1) comprising a sprung multipoint mounting (4) arranged between a vehicle seat (2) or driver'"'"'s cab and a base element (3) of a vehicle arranged below and suitable for rotative springing and/or damping of the vehicle seat (2) and/or driver'"'"'s cab in relation to the base element (3), wherein the sprung multipoint mounting (4) is formed of several pieces and comprises at least one elastomer spring element (6), and wherein the sprung multipoint mounting (4) comprises at least one separate fluid spring element and/or a fluid damping element (5), wherein the fluid spring element and/or fluid damping element (5) and the elastomer spring element (6) are arranged between the vehicle seat or the driver'"'"'s cab and the base element (3), and wherein the elastomer spring element (6) in at least one dimension has a cross section which at least in portions has substantially the form of a triangle spanned by two legs (16), wherein the legs (16) of the triangle are arranged obliquely in relation to a vertical connection between the base element (3) and an underside (8) of the vehicle seat (2) or the driver'"'"'s cab and comprises a material with elastic properties.

2. The vehicle oscillation device (1) according to claim 1, wherein the fluid spring element is an air spring and/or the fluid damping element (5) is an air bearing.

3. The vehicle oscillation device (1) according to claim 1, wherein the elastomer spring element (6) is configured for cushioning/absorbing/damping rotative and vertical and/or horizontal movements of the vehicle seat (2) or driver'"'"'s cab.

4. The vehicle oscillation device (1) according to claim 1, wherein the elastomer spring element (6) is arranged substantially parallel to a plane spanned by a vehicle longitudinal axis (7) or vehicle transverse axis and a vertical.

5. The vehicle oscillation device (1) according to claim 1, wherein the sprung multipoint mounting (4) comprises a multiplicity of physically separate elastomer spring elements (6).

6. The vehicle oscillation device (1) according to claim 1, wherein the sprung multipoint mounting (4) comprises a multiplicity of physically separate fluid spring elements and/or fluid damping elements (5).

7. The vehicle oscillation device (1) according to claim 1, further comprising a fluid spring element and/or a fluid damping element (5) remotely arranged further from a centre of an underside surface of the vehicle seat (2) or the driver'"'"'s cab than an elastomer spring element (6).

8. The vehicle oscillation device (1) according to claim 1, further comprising a fluid spring element and/or a fluid damping element (5) adapted in its springing and/or damping properties to allow an active tilt compensation of the vehicle seat (2) or the driver'"'"'s cab.

9. The vehicle oscillation device (1) according to claim 1, wherein the elastomer spring element (6) is arranged substantially parallel to a plane spanned by a vehicle longitudinal axis (7) or vehicle transverse axis and a vertical.

10. The vehicle oscillation device (1) according to claim 1, wherein the sprung multipoint mounting (4) comprises a multiplicity of physically separate elastomer spring elements (6).

11. A vehicle oscillation device (1) comprising a sprung multipoint mounting (4) arranged between a vehicle seat (2) or driver'"'"'s cab and a base element (3) of a vehicle arranged below and suitable for rotative springing and/or damping of the vehicle seat (2) and/or driver'"'"'s cab in relation to the base element (3), wherein the sprung multipoint mounting (4) is formed of several pieces and comprises at least one elastomer spring element (6), and wherein the sprung multipoint mounting (4) comprises at least one separate fluid spring element and/or a fluid damping element (5), wherein the fluid spring element and/or fluid damping element (5) and the elastomer spring element (6) are arranged between the vehicle seat or the driver'"'"'s cab and the base element (3), and wherein the elastomer spring element (6) in at least one dimension has a cross section which at least in portions has substantially the shape of the letter W, wherein at least one leg (16) of the W-shaped elastomer spring element (6) is oblique in relation to a vertical connection between the base element (3) and an underside (8) of the vehicle seat (2) or the driver'"'"'s cab and comprises a material with elastic properties.

12. The vehicle oscillation device (1) according to claim 11, wherein the elastomer spring element (6) is arranged substantially parallel to a plane spanned by a vehicle longitudinal axis (7) or vehicle transverse axis and a vertical.

13. The vehicle oscillation device (1) according to claim 11, wherein the sprung multipoint mounting (4) comprises a multiplicity of physically separate elastomer spring elements (6).
