Abstract

A wheelset bearing for the wheelset of a rail vehicle having an internally mounted truck that includes one bearing housing per side of the wheelset that encloses the wheelset bearing for the wheelset, where the wheelset bearing and bearing housing are within the wheels in an installed state and a torsion spring serves as a roll stabilizer that is connected to the bearing housing such that the torsion springs are rigidly connected to one bearing housing each on the two ends thereof (without interconnection of draw-pressure rods) so as to implement roll stabilization for the wheelsets in a manner that is as technically simple as possible.

Claims (28)

1. A wheelset bearing for a wheelset of a rail vehicle having an inside bearing truck, comprising

one bearing housing per side of the wheelset, each bearing housing enclosing a wheelset bearing for the wheelset, and the wheelset bearing and bearing housing being located inside the wheels in an installed state; and

a torsion spring comprising a roll stabilizer, said torsion spring being connected transversely to the bearing housings;

wherein the torsion spring is rigidly connected to one bearing housing at each of its two ends without tie/push rods being connected therebetween.

2. The wheelset bearing as claimed in claim 1 , wherein a middle section of the torsion spring is arranged spaced at a distance from and parallel to a wheel axis.

3. The wheelset bearing as claimed in claim 2 , wherein at least the middle section of the torsion spring serves as a carrier for at least one brake actuator.

4. The wheelset bearing as claimed in claim 3 , wherein the at least one brake actuators is a caliper brake.

5. The wheelset bearing as claimed in claim 3 , further comprising:

a wheelset;

wherein at least one brake disk is mounted on an axle of the wheelset.

6. The wheelset bearing as claimed in claim 2 , wherein the torsion spring is fabricated in one piece and is directly connected to one bearing housing in each case.

7. The wheelset bearing as claimed in claim 2 , further comprising:

levers fixedly joined to the torsion spring at each of the two ends of the torsion spring and including an angle with the longitudinal direction of the torsion spring.

8. The wheelset bearing as claimed in claim 2 , wherein at least the middle section of the torsion spring is rod-shaped.

9. The wheelset bearing as claimed in claim 1 , wherein the torsion spring is fabricated in one piece and is directly connected to one bearing housing in each case.

10. The wheelset bearing as claimed in claim 9 , wherein that the two ends of the torsion spring are formed bent relative to the middle section of the torsion spring.

11. The wheelset bearing as claimed in claim 1 , further comprising:

levers fixedly joined to the torsion spring at each of the two ends of the torsion spring and including an angle with the longitudinal direction of the torsion spring.

12. The wheelset bearing as claimed in claim 1 , characterized in that the torsion spring is fabricated from spring steel.

13. The wheelset bearing as claimed in claim 1 , further comprising:

a wheelset; and

an inside bearing truck;

wherein the bearing housing is connected in an articulated manner to a truck frame by way of a wheelset guide bushing, while no direct connection exists between the truck frame and torsion spring.

14. The wheelset bearing having a wheelset and having an inside bearing truck as claimed in claim 13 , wherein at least a middle part of the torsion spring is arranged parallel to a wheel axis in proximity to a connecting line between two wheelset guide bushings.

15. The wheelset bearing having a wheelset and having an inside bearing truck as claimed in claim 14 , wherein a bearing for realizing the connection to the frame of the truck is provided in each wheelset guide bushing, axis of rotation of the bearing including an angle with the middle section of the torsion spring.

16. The wheelset bearing having a wheelset and having an inside bearing truck as claimed in claim 14 and also having a wheelset drive, wherein at least a middle section of the torsion spring forms part of a torque support for the wheelset drive.

17. The wheelset bearing having a wheelset and having an inside bearing truck as claimed in claim 13 , wherein a bearing for realizing the connection to the frame of the truck is provided in each wheelset guide bushing, axis of rotation of the bearing including an angle with the middle section of the torsion spring.

18. The wheelset bearing having a wheelset and having an inside bearing truck as claimed in claim 13 and also having a wheelset drive, wherein at least a middle section of the torsion spring forms part of a torque support for the wheelset drive.
