Multi-unit rail vehicle for commuter traffic
Abstract:
A multi-unit rail vehicle for commuter traffic. To keep the entry and exit of the vehicle only slightly higher than the level of the street, and to make it possible to travel through the entire vehicle without steps, a continuous, level central walkway is provided that is at the same height as the entryway. To accommodate the driving bogie, the wheel sets are driven via drive shafts and reduction gear mechanisms. The drive motors can be disposed to the side below the car body and beyond the pivot range of the bogie. If room permits, vertical motors can also be provided in one corner of the car body, with such a vertical motor also driving the wheel sets via drive shafts and reduction gear mechanisms. Advantageously, two drive motors can be provided that are disposed diagonally across from one another relative to the point of rotation of the bogie, with the drive shafts of the motors being parallel to the wheel sets, and torque being transferred via further drive shafts. To accommodate the central walkway, the cross members of the bogie are angled-off. By disposing the entryway and the continuous central walkway on the same level, loading and unloading of passengers is accelerated, stopping times are reduced, and expensive platforms at the level of the vehicle floors are eliminated.
