Description

The invention relates to a device for pivoting a nose flap of a track-guided vehicle, in particular rail vehicle, and a Bugklappenmodul.

From rail vehicle technology, it is known to provide the front of a train with a bow flap, which cover the coupling shaft in the closed state to protect components or components of the clutch assembly against environmental influences, such as dirt, ice or icing. In addition, such a nose flap may have the function of avoiding aerodynamically disadvantageous front parts, which is particularly important in streamlined multiple units, such as high-speed trains, of importance.

There are known both one-piece and two-piece nose flaps known which are normally closed and only open when the clutch must be used, such as when two trains drive in double traction. In order to move a nose flap relative to the vehicle undercarriage and to release the work area for a central buffer coupling, a Bugklappen kinematics is used, which can be operated manually or automatically.

The present invention has for its object to provide a nose flap kinematics, which has a simple structure and is characterized by its reliability. In particular, a device for pivoting a bow door a track-guided vehicle and a Bugklappenmodul be given, with which due to the simple structure weight can be saved, while the susceptibility is reduced.

To solve this problem, a device is provided for pivoting a nose flap, said device having a first connectable with the nose flap pivot lever and a second connectable with the nose flap pivot lever, wherein for pivoting the nose flap relative to the vehicle underframe, the two pivot levers rotatable about a common axis of rotation are. The inventive device further comprises a first connectable to the vehicle undercarriage actuator and a second connectable to the vehicle undercarriage actuator, wherein the first actuating element cooperates with the first pivot lever such that upon actuation of the first actuating element, a torque is exerted on the first pivot lever. The second actuating element interacts with the second pivoting lever in such a way that, upon actuation of the second actuating element, a torque is exerted on the second pivoting lever. According to the invention, a synchronization element in the form of a rod-shaped element running on the first and second pivot lever is further provided, the synchronization element being connected to the first pivot lever on the one hand and to the second pivot lever on the other hand to synchronize the rotational movement of the pivot lever.

The achievable with the inventive solution advantages are obvious. By providing a rod-shaped synchronization element ensures that the two actuators, which are connected via the corresponding pivot lever with the nose flap, are always operated synchronously. Consequently, the force required to pivot the nose flap is split between the two actuators. In particular, the load on the actuating elements assigned to the individual actuating elements can thereby be reduced, so that the susceptibility to failure of the front flap kinematics can be significantly reduced. In case of failure of one of the two actuators, the bow door can still be pivoted, since the movement of the two coming to give the nose flap for use pivot lever is synchronized via the rod-shaped synchronization element.
