Abstract
Disclosed is a front suspension system having overload protection. The system comprises a mounting seat, a centering device, a support device used for supporting a coupling buffer and a coupling end pin, wherein the mounting seat is connected to a railway vehicle body, and the centering device and the support device are both installed on the mounting seat. The system further has a coupling connection seat and an overload protection element, wherein the coupling connection seat comprises a base and a coupling connection part connected as one with the base. The base is connected to a rear face of the mounting seat by means of the overload protection element. The coupling connection part passes through a through hole provided in the middle of the mounting seat and is connected with the coupling buffer by means of the coupling end pin. The coupling connection part is closely fitted with the through hole. The front suspension system has a simple structure and is lightweight.
