Abstract

The invention concerns a vehicle oscillation device with a lower part (1) and an upper part (2, 2a, 2b) positioned higher and spring-mounted in relation to the lower part (1) in the vehicle longitudinal direction (21) and/or vehicle width direction (22) by a spring device (7, 7a, 7b, 8; 18), wherein the vehicle longitudinal direction (21) and/or the vehicle width direction (22) constitute spring travel directions (9, 11), wherein at least one damper (3, 3a; 4, 4a) is arranged which extends with its longitudinal extension in a plane defined by the vehicle longitudinal direction (21) and the vehicle width direction (22), is mounted on the lower part (1) pivotably about an axis (17, 24) oriented perpendicular to the plane, and is connected with a first end (5, 5a; 6, 6a; 16) to the upper part (2).

Claims

1. A vehicle oscillation device comprising a lower part (1) and an upper part (2, 2a, 2b) spring-mounted in relation to the lower part (1) in the vehicle longitudinal direction (21) and/or vehicle width direction (22) by means of a spring device (7, 7a, 7b, 8;

18), wherein the vehicle longitudinal direction (21) and/or the vehicle width direction (22) constitute spring travel directions (9, 11), characterised by a first damper (3, 3a;

4, 4a), which extends with its longitudinal extent in a plane defined by the vehicle longitudinal direction (21) and the vehicle width direction (22), mounted pivotable on the lower part (1) about an axis (17, 24) oriented perpendicular to the plane, and connected with a first end (5, 5a;

6, 6a;

16) to the upper part (2), and by a second damper (4, 4a), a first end (6, 6a) of which is also connected with the upper part (2b) and which is mounted pivotably about the axis (24) or a further axis, wherein the two dampers (3, 4) in an undeflected position of the spring-mounted upper part (2) are arranged in their longitudinal extents on a common straight line.

2. The vehicle oscillation device according to claim 1, characterised in that the first and second dampers (3, 4) in the undeflected position of the spring-mounted upper part (2) extend in their longitudinal extents perpendicular to the spring travel direction (9, 11).

3. The vehicle oscillation device according to claim 1, characterised in that the first and second dampers (3, 3a, 3b;

4, 4a) are formed in such a way that when tensile loading is applied to the dampers (3, 3a, 3b;

4, 4a) a first damper force with damping effect is different from a second damper force with damping effect when compressive stress is applied to the dampers (3, 3a, 3b;

4, 4a).

4. The vehicle oscillation device according to claim 1, characterised in that the spring device comprises at least one first coil spring (7, 7a, 7b) extending in the spring travel direction (9, 11), a first end (14) of which is connected with the upper part (2) and a second end (15) of which is connected with the lower part (1).

5. The vehicle oscillation device according to claim 1, characterised in that the spring device comprises at least one coil spring (18) arranged in or on the at least one of the first or second dampers (3, 3a, 3b;

4, 4a), a first end (19) of the coil spring is connected with a first end (16) of the at least one of the first or second dampers (3, 3a, 3b;

4, 4a) and a second end (20) of the coil spring is connected with a second end of the at least one of the first or second dampers (3, 3a, 3b;

4, 4a).

6. The vehicle oscillation device according to claim 1, further comprising at least one elastomer part arranged in or on the damper (3, 3a, 3b;

4, 4a) to attenuate acceleration maxima of the oscillation or springing movement of the device.
