Abstract

Two rocker bearings (5,6) are located in the upper area of the gantry, between two car bodies (1,2). A first bearing is located on a console (3) of the first body, a second bearing is located offset horizontally and sideward, relative to the first bearing, on a console (4) of the second body. The first bearing has a bearing block with a slide sleeve, located at right angles to the longitudinal axis of the body. A push rod moves in the sleeve, and one end of the rod is connected to the second rocker bearing. Spring elements with stops for the bearing block are located on the push rod on either side of the bearing block.

Description

The invention relates to a roll limiter for limiting roll deflections of car bodies.

Roll limiters in the form of torsion bars generating restoring torques with actuating levers rotated in opposite directions in the event of a relative inclination of the body and chassis are known in rail vehicles with air springs, such as the "IC-Experimental" of the Deutsche Bundesbahn.

The object of the present invention is to provide a roll limiter which allows roll movements, but limits them to a certain extent and which can also be easily installed subsequently.

This object is achieved with the features mentioned in the characterizing part of claim 1. Developments and advantageous embodiments of the invention are included in the further claims.

According to the invention, two spherical bearings are arranged in the upper area of the portal between two car bodies, a first spherical bearing being arranged on a bracket of the first car body and a second spherical bearing being arranged essentially horizontally and laterally offset from the first spherical bearing on a console of the second car body. On the first spherical bearing, a slide bushing is arranged transversely to the longitudinal axis of the car body in a bearing block, in which a push rod is slidably guided, which on its one End is connected to the second spherical bearing. Spring elements with stops for them are arranged on the push rod on both sides next to the bearing block.

The spring elements advantageously have a strongly progressive characteristic curve, as a result of which the spring force rises sharply in the last two thirds of a relatively good rolling operation in the first two thirds of the total travel and thus ends the deflection relatively gently.

The spring elements are advantageously hollow rubber springs inserted under pretension. The spherical bearings are elastic ball bearings, preferably fixed bearings.

The invention is described in more detail below by way of example with reference to drawings. Show:

• Figure 1 is a plan view of a portal with roll limitation.
• FIG. 2 shows a section along the line A - A of FIG. 1;
• 3 shows a section along the line C - C of FIG. 1.

1 to 3 show a portal between two car bodies 1, 2. On the first car body 1, a console 3 is arranged in the center, which carries a first joint bearing 5. This hinge bearing consists of a ball pin 15, which is arranged as a fixed bearing on a bolt 15 ', which is firmly connected to the bracket 3. A bracket 18 for a cover 17 is connected to the bearing shell 16 of the spherical bearing 5 on the side opposite the bracket. With the bearing shell 16, or with the bearing shell Bracket 16 'is a bearing block 9 welded. The bearing block 9 carries a slide bush 10 which is arranged horizontally and transversely to the longitudinal axis of the car body 1. A sliding rod 8 is slidably guided in the sliding bush 10 and is connected at one end to a second spherical bearing 6, which is arranged laterally and horizontally offset from the first spherical bearing 5 on a bracket 4 of the second car body 2. In addition to the bearing block 9, hollow rubber springs 11, 12 are placed on the push rod 8 on both sides and held under prestress by stops 13, 14 which are firmly connected to the push rod 8.
