一种机车受电弓平衡杆的设计

Design of a Locomotive Pantograph Balance Bar

受电弓在升降弓过程中保持弓头水平的方式,目前为平衡杆方式,现开发一种通过限制受电弓弓头转轴自由度的方式,来实现此功能,以适应日益多样的线路环境。

mThe pantograph keeps the head of a bow at a level in the process of lifting the bow.At present,it is balance bar,and the paper intends to develop a way of limiting the pantograph head rotating degree of freedom to achieve the function to adapt to the increasingly diverse circuit environment.
