Abstract

A wheel set intermediate frame for a rail vehicle includes a plurality of mounting interfaces for chassis components at predetermined positions. Part of the wheel set intermediate frame for a rail vehicle is also at least one defined mounting interface for fixing to a subframe of a car body of a rail vehicle. A rail vehicle and a method for producing a wheel set intermediate frame for a rail vehicle are also provided.

First claim

The invention claimed is:

1. A rail vehicle wheel set intermediate frame for mounting a wheel set without a bogie frame on a sub-frame of a car body of a rail vehicle, the wheel set intermediate frame comprising:
longitudinal frame members each having a mounting interface for engaging against a respective longitudinal member of the sub-frame and fixedly mounting the intermediate frame to the sub-frame;
a plurality of mounting interfaces disposed at predetermined positions for chassis components;
said plurality of mounting interfaces including a mounting interface for a wheel set guide, the wheel set guide configured to transmit longitudinal forces between the wheel set and the wheel set intermediate frame and to guide the wheel set on a track; and
said plurality of mounting interfaces including a mounting interface for a braking device, the braking device positioned exactly relative to wheels of the wheel set to develop a braking effect.

2. The rail vehicle wheel set intermediate frame according to claim 1 , wherein said plurality of mounting interfaces includes a mounting interface for a drive suspension, the drive suspension including supporting elements for components for traction of the rail vehicle.

3. The rail vehicle wheel set intermediate frame according to claim 1 , wherein said plurality of mounting interfaces includes a mounting interface for a damping unit, the damping unit having a hydraulic or mechanical damping element in contact with an axle suspension.

4. The rail vehicle wheel set intermediate frame according to claim 1 , wherein the rail vehicle wheel set intermediate frame is smaller than the car body.

5. A rail vehicle, comprising a rail vehicle wheel set intermediate frame according to claim 1 .

6. The rail vehicle wheel set intermediate frame according to claim 1 , further comprising cross frame members connected between said longitudinal frame members.

7. The rail vehicle wheel set intermediate frame according to claim 1 , wherein said plurality of mounting interfaces includes a suspension mounting interface for a drive suspension, the drive suspension is connected between said suspension mounting interface and an axle bearing and said drive suspension including supporting elements for components for traction of the rail vehicle.

8. The rail vehicle wheel set intermediate frame according to claim 1 , wherein said plurality of mounting interfaces includes a suspension mounting interface for a drive suspension, said suspension mounting interface being on an underside of said longitudinal frame member opposite said mounting interface.

9. A rail vehicle wheel set intermediate frame for mounting a wheel set without a bogie frame on a sub-frame of a car body of a rail vehicle, the wheel set intermediate frame comprising:
longitudinal frame members having mounting interfaces for fixedly mounting the intermediate frame to the sub-frame;
a plurality of component mounting interfaces disposed at predetermined positions for chassis components;
said plurality of component mounting interfaces including a wheel set guide component mounting interface for a wheel set guide, the wheel set guide configured to transmit longitudinal forces between the wheel set and the wheel set intermediate frame and to guide the wheel set on a track; and
said plurality of component mounting interfaces including a braking component mounting interface for a braking device, the braking device positioned exactly relative to wheels of the wheel set to develop a braking effect, said braking component mounting interface being arranged on an underside of said longitudinal frame members.
