Problems solved by technology

However, because in exceptional cases (such as the cushioning impact of a rail vehicle approaching a stationary object), extremely high loads occur in the direction of traction, both the double-button linkage and the elastic element must be greatly oversized to prevent failure
This leads, on the one hand, to an increase in weight due to the bulky design of the double-button linkage or yoke, and, on the other hand, to reduced ride comfort, since the elastic elements are extremely rigid and thus weaken the damping of the resulting shock

Embodiment Construction

[0032] figure 1 A first transverse arm 2 and a second transverse arm 3 of the chassis frame 1 are shown, wherein the longitudinal members of the chassis frame 1 connecting the two transverse arms 2 , 3 are not shown. In this context, the transverse arms 2 , 3 extend parallel to the transverse direction 17 of the chassis frame 1 and are aligned symmetrically with respect to the longitudinal direction 16 perpendicular to the transverse direction 17 . In this context, the device for force transmission according to the invention between the chassis frame 1 and the carriage body comprises a first double-button link 4 and a second double-button link 5 as well as an intermediate connection point 11 yoke (joch)10.

[0033] The first double-button link 4 includes a first connection portion 6 and a second connection portion 8 , and is connected to the first cross arm 2 via the first connection portion 6 and to the yoke 10 via the second connection portion 8 . Similarly, the second dou...

Abstract

Device for force transfer between a chassis frame (1) and a carriage body of a rail vehicle, comprising two lemniscate links (4, 5) which are connected with the chassis frame (1) via first joints (6, 7), a yoke (10) with a middle linking point (11), in which a pivot pin (12) of the carriage body can be mounted, wherein the lemniscate links (4, 5) are connected to the yoke (10) via second joints (8 ,9) and form a Z-shaped assembly, and wherein elastically deformable elements (13) are arranged in the joints (6, 7, 8, 9) and in the yoke (10). Limiting means (14) are provided for receiving impact loads that exceed the operating load, in order to limit the maximum deflection of the middle linking point (11) of the yoke (10) in a tractive force direction (15) parallel to a tractive force acting on the chassis frame (1).

Description

technical field [0001] The invention relates to a device for force transmission between a chassis frame and a wagon body of a rail vehicle, the device having [0002] - two double-button links connected to the chassis frame via a first connection, [0003] - a yoke having an intermediate connection point in which a pivot pin of a car body can be mounted, [0004] Wherein the double-button link is connected to the yoke via the second connection part and forms a Z-shaped assembly, and wherein the elastically deformable element is arranged in the connection part and in the yoke. Background technique [0005] In general, the chassis (also called bogie) of a rail vehicle has two wheel sets which are guided on rails and connected to the car body of the rail vehicle. The main part of the chassis is the chassis frame, to which the wheelsets are connected, for example via wheel guides or the main suspension; to which the car body is connected, for example, via the secondary suspens...
