Abstract: The invention relates to a wheel axle guiding assembly comprising an axle box carrier, an axle box located longitudinally between a front part and a rear part of the axle box carrier; a front longitudinal hydro-mechanical converter between a front part of an axle box carrier and a rear longitudinal hydro-mechanical converter between the axle box and a rear part of the axle box carrier to allow a fore-and-aft movement of the axle box relative to the axle box carrier parallel to a longitudinal direction. Each of the front and rear longitudinal hydro-mechanical converters includes a housing, a plunger and an elastomeric body fixed to the housing and to the plunger so as to allow a fore-and-aft relative movement parallel to the longitudinal direction between the plunger and the housing, a single variable volume hydraulic chamber being formed between the housing, the plunger and the elastomeric body.

Abstract: In an embodiment, the present invention provides a bearing for use in a rail vehicle, including: a core assembly; a casing assembly that surrounds said core assembly, the core assembly being supported against the casing assembly by at least one membrane and being movable relative to the casing assembly; and a functional chamber, which chamber contains a working fluid, the functional chamber being delimited by a pumping surface that is formed by the core assembly and the membrane. A projection surface of the pumping surface that is orthogonal to an axial direction covers between 60% and 99% of a cross-sectional area, orthogonal to the axial direction, of the interior of the casing assembly, in which the membrane and the core assembly are received at least in part.

Abstract: A cooling water pump for a pump housing of an internal combustion engine includes a bearing cover that can be fixed within a bore of the pump housing. The pump also includes a pump shaft and a bearing. The pump shaft is rotatably mounted in the bearing. An impeller and a pulley are each coupled to the pump shaft, and the impeller has an inlet opening that is circular in shape and concentric with the impeller. The inlet opening is disposed at the end of the impeller that faces the pump housing in the axial direction. A first concentrically formed covering covers the impeller and is impermeable to liquids flowing in the axial direction. The first covering is disposed in first zones located radially beyond the inlet opening, and the impeller is open in second zones located on a side of the impeller axially opposite the first covering.

Abstract: The plastic impeller of a coolant pump is attached to the bearing shaft with a bearing journal, so that the journal engages to be seated firmly in an axial bore of the shaft. Here, the bearing journal and the impeller are formed in one piece of the same material. The bearing journal is pressed or glued into the bore of the bearing shaft, and the impeller as well as the bearing journal are formed of a phenolic resin which is resistant to the coolant.
