Abstract

A spring arrangement for a vehicle, particularly a rail vehicle with at least one wagon and at least one bogie, wherein so as to create favorable construction conditions the spring arrangement includes at least one suspension spring, at least one pre-stressed damping spring, a contact body connected to the damping spring, and at least one first auxiliary spring, where a first longitudinal axis of the suspension spring, a second longitudinal axis of the damping spring, a third longitudinal axis of the contact body, and a fourth longitudinal axis of the first auxiliary spring are arranged parallel to each other, and where the contact body is arranged between the damping spring and the first auxiliary spring such that a low level of overall rigidity of the spring arrangement is obtained for a height adjustment of the vehicle.

Claims (32)

1. A spring arrangement for a vehicle having at least one car body and at least one running gear, the spring arrangement comprising:

at least one suspension spring;

at least one pre-stressed damping spring;

a contact body which is connected to the at least one damping spring; and

at least one first auxiliary spring are provided;

wherein a first longitudinal axis of the at least one suspension spring, a second longitudinal axis of the at least one damping spring, a third longitudinal axis of the contact body and a fourth longitudinal axis of the at least first auxiliary spring are arranged parallel to one another; and

wherein the contact body is arranged between the at least one damping spring and the at least first auxiliary spring.

2. The spring arrangement as claimed in claim 1 , wherein the at least one damping spring is arranged connectable in series with respect to the at least first auxiliary spring.

3. The spring arrangement as claimed in claim 2 , wherein the at least one suspension spring is arranged connectable in parallel with respect to the at least one damping spring and the at least first auxiliary spring.

4. The spring arrangement as claimed in claim 1 , wherein the at least one suspension spring is arranged connectable in parallel with respect to the at least one damping spring and the at least first auxiliary spring.

5. The spring arrangement as claimed in claim 1 , wherein the fourth longitudinal axis of the at least first auxiliary spring is arranged parallel to a fifth longitudinal axis of a second auxiliary spring.

6. The spring arrangement as claimed in claim 1 , further comprising:

a hydraulic cylinder; and

a first hydraulic piston which contacts the at least one damping spring that is arranged in the hydraulic cylinder, said first hydraulic piston being arranged to protrude into the hydraulic cylinder.

7. The spring arrangement as claimed in claim 6 , further comprising:

a piston rod arranged to protrude into the hydraulic cylinder.

8. The spring arrangement as claimed in claim 7 , wherein the piston rod is connected to the at least one running gear.

9. The spring arrangement as claimed in claim 8 , wherein the first hydraulic piston is configured as an actuator with respect to the piston rod.

10. The spring arrangement as claimed in claim 8 , further comprising:

a second hydraulic piston arranged in the hydraulic cylinder;

wherein the second hydraulic piston is configured as an actuator with respect to the first hydraulic piston and is connected to the piston rod via a compression spring.

11. The spring arrangement as claimed in claim 7 , wherein the piston rod is connected to the at least one car body.

12. The spring arrangement as claimed in claim 11 , wherein the first hydraulic piston is configured as an actuator with respect to the piston rod.

13. The spring arrangement as claimed in claim 11 , further comprising:

a second hydraulic piston arranged in the hydraulic cylinder;

wherein the second hydraulic piston is configured as an actuator with respect to the first hydraulic piston and is connected to the piston rod via a compression spring.

14. The spring arrangement as claimed in claim 1 , wherein the at least one suspension spring is configured as a secondary spring.

15. The spring arrangement as claimed in claim 1 , wherein the at least one suspension spring comprises a helical spring.

16. The spring arrangement as claimed in claim 1 , wherein the at least one damping spring comprises a helical spring.

17. The spring arrangement as claimed in claim 1 , wherein at least the first auxiliary spring comprises an elastomer spring.

18. The spring arrangement as claimed in claim 1 , wherein the second auxiliary spring comprises a layer spring.

19. The spring arrangement as claimed in claim 1 , wherein the vehicle is a rail vehicle.
