Work vehicle for carrying out work operations on a track

Abstract

The invention relates to a work vehicle for carrying out work operations on a track, comprising a vehicle frame which can be moved on the track supported on rail running gears, a drive cab which is connected to the vehicle frame, and various mounted structures with assigned functions for a work operation. The mounted structures are designed as self-supporting function modules with predefined interfaces and connected to the vehicle frame and/or each other by means of threaded connections. The predefined interfaces enable the interconnection of different function modules without further adaptations. All modules are continuously checked with regard to their geometry and their functions to enable joinability in the final assembly without welding and adjustment processes.

         3 . The work vehicle according to  claim 1 , wherein the predefined interfaces comprise joining elements which enable an adjustment of the respective function module, in particular, in two directions orthogonal to each other. 
     
     
         4 . The work vehicle according to  claim 1 , wherein the predefined interfaces comprise joining elements that have a unique geometric fit to each other. 
     
     
         5 . The work vehicle according to  claim 1 , wherein the vehicle frame comprises two lateral longitudinal carriers, the upper edges of which span a vehicle floor, and in that at least one function module is arranged as an underfloor module below the vehicle floor. 
     
     
         6 . The work vehicle according to  claim 5 , wherein the respective longitudinal carrier comprises a longitudinal-carrier upper flange and a longitudinal-carrier lower flange, which are connected to one another by a plurality of connecting elements arranged at equal distances from one another. 
     
     
         7 . The work vehicle according to  claim 5 , wherein an underfloor module is designed as a traction module and in that the traction module comprises an internal combustion engine coupled to a generator and/or a pump distributor gearbox. 
     
     
         8 . The work vehicle according to  claim 1 , wherein at least one function module is designed to be shiftable on guides in relation to the vehicle frame. 
     
     
         9 . The work vehicle according to  claim 8 , wherein the shiftable function module is fastened to an auxiliary frame. 
     
     
         10 . The work vehicle according to  claim 1 , wherein the vehicle frame is divided into three sections in the longitudinal direction, in that the drive cab is arranged on one end section, in that a crane module or a further cab is arranged on the other end section, and in that further function modules are set up on the middle section. 
     
     
         11 .
