HIGH EFFICIENCY SEMI-ARTICULATED RAILWAY POWER TRUCK

摘要

HIGH EFFICIENCY SEMI-ARTICULATED RAILWAY POWER TRUCK A semi-articulated railway power truck has in preferred embodiment a pair of dual axle sub-trucks semi-articulated for creep force balancing turning control while retaining freedom of rocking and relative longitudinal motion. An equalized centered bolster suspension and low traction rod linkage maintain high equalization of loads and tractive forces at the wheels to provide overall high adhesion and curving efficiency.
