Monotrace type trolley for trolley train, has reversible locking unit to lock axle in position with respect to chassis, where unit co-operates with drawbar such that locking unit is unlocked when drawbar is subjected to lateral force

摘要

#CMT# #/CMT# The trolley (1) has a chassis (3) supported by an axle (2) that is mounted pivotably around a vertical axis (10). The chassis has a drawbar (7) mounted pivotably around the vertical axis, where the drawbar co-operates with the axle and orients the axle. A reversible locking unit (13) locks the axle in position with respect to the chassis. The locking unit co-operates with the drawbar such that the locking unit is unlocked and locked when the drawbar is subjected and not subjected to a sufficient lateral force, respectively. #CMT#USE : #/CMT# Monotrace type trolley for use in a trolley train for being pulled by a tractor to transfer a motor vehicle part in a fabrication line. #CMT#ADVANTAGE : #/CMT# The reversible locking unit locks the axle in position with respect to the chassis, thus enabling the train having five trolleys to move at a speed higher than ten kilometers, without being hindered by untimely wandering phenomenon due to centrifugal force or obstacles placed on ground, and hence increasing the productivity of the motor vehicle parts. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial sectional front view of a drawbar of an axle and a unit locking the axle with respect to a chassis of a trolley. 1 : Monotrace type trolley 2 : Axle 3 : Chassis 7 : Drawbar 10 : Vertical axis 13 : Reversible locking unit.
