Problems solved by technology

[0007] The known apron, which is mounted laterally on the bogie of a rail vehicle, ignores the aerodynamic properties of the underside of the chassis, and the rotatable side covering elements with the likewise rotatable bottom elements create a negative impact on the side covering elements. complex suspension and reduces driving stability due to its relatively large moment of inertia about the vertical axis of the chassis

Embodiment Construction

[0038] exist figure 1 The occluded chassis in the perspective view from the side below is indicated in . Recognized are the side elements 1 , the bottom element 3 , which is designed as a flat floor, and the two transition elements 6 , which cover the chassis, which is here embodied as a bogie. The side elements 1 are not visible here on the rear of the chassis. The wheels 5 are only partially discernible from the chassis.

[0039]The bottom element 3 is substantially rectangular except for the rectangular notches 7 on its straight longitudinal sides and the roundings in the shape of a circular arc at its ends. The transition element 6 adjoins the base element 3 on both sides, wherein there is only a narrow annular gap between the arc-shaped end of the base element 3 and the likewise arc-shaped transition element 6 .

Abstract

The invention relates to a rail vehicle having a concealed undercarriage, particularly a bogie, wherein the covering comprises at least side elements (1) that are arranged along the rail vehicle on the sides of the undercarriage and a bottom element (3) that is arranged on the underside of the undercarriage. According to the invention: -the side elements (1) are fixedly connected to the carriage body of the rail vehicle; - the bottom element (3) is fixedly connected to the undercarriage; and - a gap (8) is provided between the bottom element (3) on one side and the side elements (1) on the other side, said gap providing a distance between the wheels (5) of the undercarriage and the bottom element (3) on one side and the side elements (1) on the other side, both in the fully turned and in the partially turned state of the undercarriage.

Description

technical field [0001] The invention relates to a rail vehicle having a chassis, in particular a bogie, with a shade, wherein the shade comprises at least side elements arranged along the rail vehicle on the sides of the chassis and a bottom element arranged on the underside of the chassis superior. [0002] The invention can be used on bogies, in particular built-in bogies, where bearings and frame parts are located between wheels or wheel discs. Background technique [0003] The running resistance of a train, especially a high-speed train, is largely determined by the aerodynamic running resistance. This aerodynamic running resistance includes a relevant part of the resistance from the underbody of the rail vehicle, in particular from the free space required for the movement of the chassis below the carriage. These free spaces are also disadvantageous for the acoustic properties of the rail vehicle. [0004] In order to achieve an improvement in this regard, it is known...
