COUPLING GEAR FOR CONNECTING TRUCK-TRACTOR WITH WHEELED TRAILER Russian patent published in 1999 - IPC

Abstract RU 2127198 C1

FIELD: transport engineering; towing gears with hydraulic shock absorbers. SUBSTANCE: proposed coupling gear has second plunger with throttling holes connected with truck-tractor and arranged inside space of rod of first plunger, second spring, valves to control clearance of throttling holes of first plunger. Control inputs of valves are connected with output of hydraulic sensor converting deformation of spring into oil pressure change. Area of cross section of throttling holes of second plunger is 0.4-0.95 of area of cross section of throttling holes of first plunger. EFFECT: enhanced dynamic characteristics of coupling gear. 7 dwg
