The invention discloses a ground power supply electric vehicle powered shoe lifting suspension device which comprises a four-bar mechanism, the upper end of the four-bar mechanism is connected to a vehicle chassis through a pivot, and the lower end of the four-bar mechanism is connected with a powered shoe. A push rod mechanism is fixed to the vehicle chassis, and a push rod of the push rod mechanism right faces a lateral pivot of the four-bar mechanism so as to drive the lateral pivot to move towards the two sides. And a limiting device is arranged and limits the position of the lateral pivot of the four-bar mechanism, and after the power push rod retracts and breaks away from the contact with the lateral pivot, the limiting device bears the gravity of the collector shoe. According to the lifting suspension device for the collector shoe of the ground power supply electric vehicle, by arranging the limiting device, the lowest position of the lateral pivot of the four-bar mechanism is limited, so that when the four-bar mechanism is lowered to the lowest state, the gravity of the four-bar mechanism is borne through the limiting device, the push rod does not bear excessive pressure any more, and damage to the push rod is effectively avoided. The limiting device is simple in structure, not prone to damage, low in cost and convenient to replace.
本发明公开了一种地面供电电气车辆受电靴升降悬挂装置,包括四连杆机构,四连杆机构上端枢轴连接至车辆底架,下端连接受电靴;推杆机构固定于车辆底架,推杆机构的推杆正对四连杆机构的侧向枢轴,以驱动侧向枢轴向两侧移动;限位装置,限位装置限位所述四连杆机构的侧向枢轴的位置,当动力推杆回缩脱离与侧向枢轴的接触后,由限位装置承担受电靴的重力。本发明提供的地面供电电气车辆受电靴升降悬挂装置,通过设置限位装置,对四连杆机构的侧向枢轴的最低位置进行限位,从而使得四连杆机构在降低至最低状态时,依靠限位装置承受其重力,推杆不再过度承压,有效避免对推杆的损坏,且限位装置结构简单,不易损坏,成本低廉,更换也较为方便。
