Abstract

A wheel set for a rail vehicle, in particular for a locomotive, includes two track wheels which are connected by a wheel axle mounted in two wheel set bearings. Each wheel set bearing includes a cast bearing housing, which is closed by an outer housing cover and an inner pressure ring. In addition, the bearing housing has a clamping position for engaging a tensioning device of a machine tool for machining the wheel set. Since the clamping position is integrated in the pressure ring, the clamping position can be easily cut to size and the bearing housing can be produced in a weight-optimized and cost-effective way in comparison to known bearing housings.

First claim

The invention claimed is:

1. A wheel set for a rail vehicle or a locomotive, the wheel set comprising:
two wheel set bearings each having a cast bearing housing;
two track wheels;
a wheel axle interconnecting said two track wheels and being mounted in said two wheel set bearings;
each bearing housing having a respective outer side with an outer housing cover and a respective inner side opposite said respective outer with respect to a longitudinal direction of said wheel axle, said respective inner side having an inner pressure ring;
each said inner pressure ring having a respective outside diameter;
fasteners disposed about an outer periphery of each said inner pressure ring within said respective outside diameter for fastening each said inner pressure ring to said respective inner side; and
each said inner pressure ring having a clamping structure integrated therein for engaging a tensioning device of a machine tool for machining the wheel set, said clamping structure being at least one clamping strap projection projecting radially outward from said respective outside diameter.

2. The wheel set according to claim 1 , wherein said clamping structure is formed by two diametrically oppositely disposed clamping straps radially projecting on an outer periphery of said pressure ring.

3. The wheel set according to claim 1 , wherein said clamping strap has at least one through-hole for engaging the tensioning device.

4. The wheel set according to claim 1 , wherein said clamping strap extends radially downward from said inner pressure ring.

5. The wheel set according to claim 4 , wherein said clamping strap is constructed for being engaged by clamping arms of a lathe.
