TRACK MEASURING TRUCK Russian patent published in 2007 - IPC B61K9/08 

FIELD: railway transport.

SUBSTANCE: invention relates to means of checking condition of rail tracks. Proposed track measuring truck includes two recoil wheels rigidly connected in axial direction by base member on which measuring wheels are installed, being mechanically intercoupled. Base member is made in form of sealed hollow frame with parallelogram mechanisms on ends. Guide hollow shafts with stop-shock absorber on end are tightly fitted on end faces of hollow frame for fixing and turning around own axis. Turnable recoil wheel with friction shock absorber on working face is secured on end of hollow shaft, and hollow cup is installed for hermetic axial displacement. Conical hub of measuring wheel is installed on cup for rotation to which rim of measuring wheel with inner conical surface is fastened through conical shock absorber. Conical hub of measuring wheel together with hollow cup is connected through inner space of guide hollow shaft with articulated leverage arranged in sealed space of frame. Axle of central rocker is hermetically installed on hollow frame passing through its center and is coupled at one outer side with shaft of following wheels travel sensor installed on outer side of hollow frame, and at other outer side, with following wheels drive lever on which guide for checking displacement of measuring wheel relative to body is hinge mounted. Axle of following wheels travel sensor is enclosed and fixed in space of axle of central lever by shock absorber compressed in closed space by threaded rod arranged inside central rocker axle.

EFFECT: provision of smooth adjustment of pressure and release forces of following wheel, high-shock absorbing properties of truck at impacts.
