Abstract
The invention relates to a vehicle oscillation apparatus with a horizontal springing device which is arranged between a vehicle seat and/or a driver's cab and a base element of a vehicle and which is suitable for the horizontal springing and/or damping of the vehicle seat and/or the driver's cab with respect to the base element, wherein the horizontal springing device is arranged substantially parallel to a surface of the base element and comprises an elastomer spring element which has a characteristic spring curve.
Claims18
A vehicle oscillation apparatus, comprising:
- a horizontal springing device located between a vehicle seat or a driver's cab and a base element of a vehicle and which is configured for the horizontal springing and damping of the vehicle seat or the driver's cab with respect to the base element, wherein the horizontal springing device is arranged substantially parallel to a surface of the base element and comprises, in a vertical direction, a flat shaped elastomer spring element, wherein said elastomer spring element is deformable in a horizontal direction parallel to a longitude direction in a plane containing the longitude direction and a transverse direction of the vehicle and has a spring characteristic curve, wherein the elastomer spring element is directly connected to the base element, and wherein the elastomer spring element used is capable of being loaded under tension, wherein the elastomer spring element is connected to the vehicle seat by two bearings, wherein the two bearings are received by elongated recesses in the elastomer spring element, and wherein each of the two bearings has a freewheel in which the vehicle seat is freely movable locally in the longitudinal direction of the vehicle without deforming the elastomer spring element.
