DEVICE FOR MEASURING AND INDICATING STATE OF LOAD OF BOLSTER-TYPE TRAILER

摘要

FIELD: transport engineering. SUBSTANCE: flexible meter is arranged on wheeled truck-tractor coupling gear for connection with bolster-type trailer between sliding plate and coupling gear plate of wheeled truck-tractor in zone of pivot of bolster-type trailer. Flexible member is made in form floating member of pneumatic suspension or resilient member with dynamometric pressure or force transmitter or travel transmitter. On one of truck-tractor and/or bolster-type trailer axle provided with pneumatic suspension with right-hand and left-hand resilient members at least one other pressure or force transmitter is installed which is pneumatically connected with delivery spaces of resilient members, pressure transmitters being connected with electric indicating device. EFFECT: enhanced efficiency. 3 dwge
