The invention relates to a track-measuring vehicle (1) for recording a track geometry of a track (2), having a vehicle frame (5) which can move on two rails (3) of a track and has rail bogies (4), and having a first measuring base (7) on which an inertial measuring unit (8), and at least one contactless position-measuring device (9) for determining the position with respect to each rail (3), are arranged. There is provision here that a lowerable second measuring base (11) is arranged, which second measuring base (11) comprises measuring running wheels (12), which can be set down on the rails (3), and is connected to the first measuring base (7) via compensation-measuring devices (20, 22).

    L'invention concerne un véhicule d'auscultation de voie (1) permettant l'acquisition d'une géométrie d'une voie (2), lequel comprend un châssis de véhicule (5), qui peut se déplacer sur deux rails (3) d'une voie et qui comporte des organes de roulement ferroviaire (4), et une première base de mesure (7) sur laquelle sont disposés une unité de mesure inertielle (8) et au moins un dispositif de mesure de position sans contact (9) permettant une détermination de position vis-à-vis de chaque rail. Selon l'invention, une deuxième base de mesure (11) abaissable est mise en place, laquelle comprend des roues porteuses de mesure (12) pouvant être posées sur les rails (3) et est reliée à la première base de mesure (7) par l'intermédiaire de dispositifs de mesure de compensation (20, 22).
