Measuring instrument for determining the actual condition of wheel sets
First Claim
1. A measuring instrument, positioned in a track panel of a railway track, for determining actual condition of wheelsets and wheels of a railway vehicle passing by using several optical beam devices, with the measuring instrument featuring a first section for rolling in a wheelset under lateral guidance of the wheelset, a measurement section with an auxiliary rail for supporting the wheelset on the outer edges of its two wheels and a third section for rolling out the wheelset into the railway track, with the first and third section of the measuring instrument also designed as track panels and flexibly embedded in a ballast of the superstructure of the railway track and of which the optical beam devices are positioned beneath the measurement section and mounted vibration-free on a base plate on a formation of the railway track in a pre-determined position in relation to the measurement section of the measuring instrument with no contact to the other parts of the measuring instrument, with the base plate designed as first trough, circumferentially enclosed by side walls, with several coverings which each have a recess in the area of the beam path and can be opened during measurements, wherein a first trough is positioned within a second trough at an approximately even distances to walls all round.

Abstract
A measuring instrument has a first section for rolling a wheelset under lateral guidance of the wheelset into a measurement section with an auxiliary rail for supporting the wheelset on the outer edges of its wheels and a third section for rolling out the wheelset into the railway track, with the first and third section of the measuring instrument also designed as track panels and for which the optical beam devices under the measurement section are intended. The first and third section of the measuring instrument are flexibly embedded in the ballast of the superstructure of the railway track, while at least one of the optical beam devices is mounted vibration-free on the formation of the railway track in a pre-determined position in relation to the measurement section of the measuring instrument with no contact to the other parts of the measuring instrument.
