在工程机械诞生的100多年历程中,几次关键性的配套件的升级引发了世界工程机械行业革命性的变化。第一次是柴油机代替汽油机;第二次是液压操纵代替机械操纵;第三次是液力变矩器的出现,液力机械传动代替机械传动;第四次是行走机械铰接式转向代替刚性车架的偏转车轮转向。可以说,世界工程机械行业的发展史就是工程机械配套件的进化史,而液压技术作为一种颠覆性技术,催生了工程机械行业的革命性发展。
In the 100 years of construction machinery was born, several key components of the upgrade caused a revolutionary change in the world construction machinery industry. The first is the diesel engine instead of the gasoline engine; the second is the hydraulic control instead of the mechanical control; the third is the emergence of the hydrodynamic torque converter, hydraulic mechanical transmission instead of the mechanical transmission; the fourth is walking mechanical articulated steering instead of the rigid car Deflection of the frame Wheel steering. It can be said that the history of the world’s construction machinery industry is the history of the evolution of construction machinery parts, hydraulic technology as a disruptive technology, gave birth to the revolutionary development of construction machinery industry.
