| description | A hydraulic bearing sleeve and a railway vehicle chassis, the hydraulic bearing sleeve (1) having:-an annular rubber body (3) comprising an inner sleeve (2) for receiving a bearing journal (12); an outer annular housing (6) on the inner circumference of which the annular rubber body is supported; -at least two chambers (7, 8) which are designed between the annular rubber body and the annular housing or inside the rubber body and which can be filled with hydraulic fluid and which are connected to one another by means of at least one balancing and throttling channel (9) such that hydraulic fluid can be exchanged between the chambers when the inner sleeve is subjected to a load due to a bearing force. A reinforcing support (13, 14) having a greater modulus of elasticity than the rubber material is arranged in or on the annular rubber body such that, when the pressure in one of the chambers increases, the stretching of the rubber body corresponding to the expansion or shape change can be reduced at least in one d |
