Device for transmitting a force between the chassis and body of a rail vehicle
A device transmits a force between a chassis and a body of a rail vehicle. The device is a structurally simple, space-saving device which allows spring movements and rotational movements of the body relative to the chassis. This is achieved in that at least one first traction link buffer, which has a first end face, and at least one second traction link buffer, which has a second end face, are fixed to the chassis. The first end face is spaced from the second end face in a longitudinal direction of the rail vehicle. The two end faces point in at least approximately opposite directions, and a stop plate with sliding portions which are mutually spaced in the longitudinal direction is provided on the body. The end faces of the traction link buffers rest against the sliding portions in a slidable manner at least along some sections.
1. A device for transmitting a force between a chassis and a rail car body of a rail vehicle, the device comprising:
traction link buffers including at least one first traction link buffer having a first end face and at least one second traction link buffer having a second end face fixed to the chassis, the chassis and the rail car body being separate components of the rail vehicle, said first end face disposed at a distance from said second end face in relation to a longitudinal direction of the rail vehicle, said first and second end faces face in at least approximately opposite directions; and
a stop plate disposed on the rail car body and having mutually spaced sliding portions in the longitudinal direction, said first and second end faces of said traction link buffers abut at least in sections in a slidable manner with said sliding portions for transmitting forces in the longitudinal direction of the rail vehicle between the chassis and the rail car body.
2. The device according to claim 1 , wherein:
said at least one first traction link buffer and said at least one second traction link buffer are fixed to a cross-member of the chassis; and
said stop plate is a fork having limbs with, in each case, one of said sliding portions facing one of said first or second end faces.
3. The device according to claim 2 , wherein the cross-member with the first and second traction link buffers attached thereto is disposed centrally in the chassis with reference to the longitudinal direction of the rail vehicle.
4. The device according to claim 1 , wherein said sliding portions are movable parallel to a vertical direction and/or to a transverse direction.
5. The device according to claim 1 , further comprising slide plates each having a slide surface, in each case one of said slide plates with said slide surface fixed to one of said first or second end faces in a replaceable manner.
6. The device according to claim 5 , wherein said slide plates are manufactured from plastic.
7. The device according to claim 5 , wherein said slide plates have a circular form, seen in the longitudinal direction.
8. The device according to claim 1 , wherein said at least one first traction link buffer and/or said at least one second traction link buffer take a form of multi-layer elastomer buffers.
9. The device according to claim 1 , wherein the rail car body with said stop plate is rotatable relative to the chassis about an axis of rotation which extends parallel to a vertical direction.
10. The device according to claim 1 ,
wherein said traction link buffers have a base plate and are fixed by screwing said base plate to a cross-member of the chassis; and
further comprising at least one adjustment insert disposed between the cross-member and said base plate.
