VEHICLE FOR CARRYING TWO-TRACK MECHANIZED SECTIONALIZED BRIDGE WITH ADJUSTABLE TRACK GAUGE Russian patent published in 1998 - IPC

FIELD: transport engineering; bridge crossing facilities. SUBSTANCE: vehicle for carrying two-track mechanized sectionalized bridge with adjustable track gauge has tractor and trailer which carry bunks with vertical posts for fixing the bridge from lateral cross displacement on their frames. Vehicle is furnished with mechanisms to change track gauge and track gauge limiters installed in fixed angular position in intertrack space along axis of sectionalized bridge for re-placement on vehicle bunks from travelling into working positions and back. Each track gauge adjuster has central fixed pipe rigidly secured to corresponding frame and movable outer pipes installed on ends of fixed pipe for radial longitudinal displacement relative to fixed pipe under action of drive and for locking by means of screw lock secured on each movable pipe for engagement with radial through slots made on fixed pipe provided with supports in base for engagement with longitudinal slots of movable pipe. Upper part of each track gauge limiter is made in form of sidemember whose central webs are coupled with bushing installed on axle secured on central fixed pipe of corresponding track gauge adjuster. Bushing is installed on axle with clearance of 0.05-0.1 mm of its fit size. EFFECT: enlarged operating capabilities. 3 cl, 10 dwg
