An assembly for transmitting longitudinal forces in a rail vehicle, the assembly comprising:
- a wheelset;
- a truck;
- and
- hydraulic axle link bearings including a first axle link bearing and a second axle link bearing, each of said hydraulic axle link bearings having an outer housing element, an inner housing element, a damping element, and two chambers including a first chamber and a second chamber filled with a fluid, said two chambers disposed opposite to one another between said inner housing element and said outer housing element, such that in an event of a change in a position of said inner housing element relative to said outer housing element, an alternately occurring change in a volume of said two chambers is caused via an exchange of the fluid, wherein each of said hydraulic axle link bearings further have two external connections and each of said two chambers of an axle link bearing of said hydraulic axle link bearings is connected to a respective one of said external connections, wherein each of said axle link bearings is connected both to said truck and to said wheelset by way of said inner and outer housing elements, in order to transmit the longitudinal forces formed by the rail vehicle during travel between said wheelset and said truck, wherein, in a case of each of said hydraulic axle link bearings, the longitudinal forces cause a change in a position of said inner housing element relative to said outer housing element and thus an alternating change in volume in said two chambers due to the exchange of the fluid, wherein said first chamber of said first axle link bearing is connected to said first chamber of said second axle link bearing by way of said damping element for the exchange of the fluid, and wherein said second chamber of said first axle link bearing is connected to said second chamber of said second axle link bearing directly for the exchange of the fluid, wherein said damping element is in a form of a cylinder which is filled with the fluid and which has an integrated ram, and wherein said integrated ram is disposed such that the fluid of said two first chambers which acts on said integrated ram during the exchange of the fluid causes a damped movement of said integrated ram in said cylinder;
- said external connections including a first connection and a second connection;
- said inner housing element having a first duct and a second duct, said first chamber is connected to said first connection by way of said first duct which runs inside said inner housing element;
- said first connection being disposed as part of said inner housing element in an outer region of said axle link bearing;
- said second chamber being connected to said second connection by way of said second duct which runs inside said inner housing element;
- and
- said second connection being disposed as part of said inner housing element in the outer region of said axle link bearing.
