Device for pivoting one or more nose flaps of a track-guided vehicle
The invention relates to a device for pivoting one or more nose flaps of a track-guided vehicle, a railway vehicle in particular. It is hereby provided for the device to comprise at least one supporting frame ( 10 ) connected or connectable to the vehicle undercarriage and at least one actuating device connected on one side to the at least one supporting frame ( 10 ) and on the other to the pivotable nose flap ( 1 a; 1 b ) for pivoting the nose flap ( 1 a; 1 b ) relative to the supporting frame ( 10 ) from a closed state into an opened state and vice versa, wherein the actuating device comprises at least one lifting spindle drive ( 30 a, 32 a; 30 b, 32 b ).
1. A device for pivoting one or more nose flaps of a track-guided vehicle, wherein the device comprises the following:
at least one supporting frame connected or connectable to an undercarriage of the track-guided vehicle;
at least one actuating device connected to the at least one supporting frame and connected to a pivotable nose flap for pivoting the nose flap relative to the supporting frame from a closed state into an opened state and vice versa, wherein the actuating device comprises a first lifting spindle drive and a second lifting spindle drive, whereby the first lifting spindle drive and the second lifting spindle drive are configured to pivot the nose flap; and
a synchronizing element in the form of a rod-shaped element configured to synchronize actuation of the first lifting spindle drive and the second lifting spindle drive.
2. The device according to claim 1 , wherein the actuating device comprises an electrically, pneumatically or hydraulically operated first lifting spindle drive and an electrically, pneumatically or hydraulically operated second lifting spindle drive.
3. The device according to claim 1 , wherein the actuating device comprises a servomotor to actuate one of the first lifting spindle drive and the second lifting spindle drive.
4. The device according to claim 1 , wherein the first lifting spindle drive and the second lifting spindle drive can be actuated manually.
5. The device according claim 1 , wherein each of the first lifting spindle drive and the second lifting spindle drive comprises a housing and a lifting spindle mounted in the housing, wherein the lifting spindle can be extended and retracted relative to the housing by actuating the respective lifting spindle drive.
6. The device according to claim 5 , wherein the housing of the lifting spindle drive is connected to the at least one supporting frame so as to be pivotable in the vertical or horizontal plane.
7. The device according to claim 5 , wherein the lifting spindle is articulated to a lever element which is articulated to the at least one supporting frame by means of a bearing so as to be pivotable in the vertical or horizontal plane.
8. The device according to claim 7 , wherein the lever element is connected to the nose flap associated with the respective lifting spindle drive such that the nose flap will pivot upon actuation of the respective lifting spindle drive.
9. The device according to claim 1 , wherein the first lifting spindle drive and the second lifting spindle drive each comprises a spindle nut and a spindle nut-mounted lifting spindle, and wherein the synchronizing element connects to the first lifting spindle drive on one side and to the second lifting spindle drive on the other.
10. The device according to claim 1 , wherein a first actuating device is provided to pivot a first nose flap and a second actuating device is provided to pivot a second nose flap.
11. The device according to claim 10 , wherein the first nose flap is designed so as to pivot upward in a vertical plane relative to the supporting frame by means of the first actuating device, and wherein the second nose flap is designed so as to pivot downward in a vertical plane relative to the supporting frame by means of the second actuating device.
