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.

The patent was disclosed a telescopic mechanism in a telescopic hitch buffer device for use in high speed electric multiple unit (EMU) trains. The telescopic mechanism comprises a compression rod () located inside a movable housing () of said hitch buffer device, one end of said compression rod () being connected to the movable housing (), and a bearing connector () encasing the compression rod (). A guiding barrel () is fixedly mounted outside the bearing connector (). An extension/retraction driving mechanism () is provided between the guiding barrel () and the movable housing (). A locking mechanism comprises protrusions () distributed at the other end of the compression rod (), and grooves () in engagement with protrusions () on the inner wall of the bearing connector (). One end of the compression rod () is connected to the movable housing () via a torsion spring (), keeping the compression rod () and the bearing connector () in a locked state; an unlocking driving mechanism is provided on the outside of the movable housing (), and is in an unlocked state when the protrusions () face the grooves (), in which case, the movable housing () and the bearing connector () can slide relative to each other. Since the extension/retraction driving mechanism () is provided inside the movable housing (), volume is reduced, good protection is provided for respective components, and the telescopic mechanism and the locking mechanism are relatively simple in structure, labor-saving, reliable in operation, and can bear relatively large loads.
