Regio-Shuttle RS1, operated by Erfurter Industriebahn GmbH

The Regio-Shuttle RS1, a product of Stadler, is manufactured by Stadler Pankow GmbH in Berlin. Since 1996, more than 350 trains have been delivered to 17 German public transport providers, 23 of them to Erfurter Industriebahn GmbH (EIB), which operates its fleet in Thuringia and on five lines in the northern part of Lower Franconia.

The design, which is reminiscent of a truss bridge girder, gives the Regio-Shuttle RS1 a distinctive appearance.As the trains are equipped with a

pneumatic spring system, they run

with a smoothness that is unusually

high for local trains.

The single-unit Regio-Shuttle RS1

was designed for single driver

operation and as an independent

rail car unit, but up to six units can

be coupled together (multi-traction).

With high acceleration rates and a

maximum speed of120 km/h, the

Regio-Shuttle RS1 can easily be

integrated into main line traffic.

As the low-floor portion of the

trains totals ca. two thirds, and the

entrance height is very low,

passengers can board and exit

comfortably.

Schaeffler Group Industrial

supplies FAG rolling bearings for

the wheelset reverse gear units of

all

Regio-Shuttle RS1 trains.

The wheelset reverse gear unit is a spur-bevel gear for coupled wheelsets. The torque is applied to the

transfer axle via the input shaft. One half of the torque is transmitted directly to the driving axle of the transfer axle drive via the bevel pinion shaft. By means of a FAG bearings

Input shaft:

The input shaft is supported in a cylindrical roller bearing NU212-E and an angular contact ball bearing pair 7216-B . Axial forces that act on the input shaft’s input flange are taken up by the angular contact ball bearing pair.

Loose wheels:

The two loose wheels are supported in 2 tapered roller bearings F-804622.TR1(special design) each (X-arrangement).

Intermediate shaft:

The intermediate shaft is supported in 2 cylindrical roller bearings NJ2211-E of NJ design.

Bevel pinion shafts:

At the bevel pinion shafts, two cylindrical roller

bearings NU2219-E und F-803167.NU2220-E (special design) each take up the radial loads whereas a four point bearing QJ219each takes up the axial forces from the gearing. These bearings also take up the forces from the universal joint shaft.

Output shafts:

The output shafts are supported in two tapered roller bearings F-800163.TR1(special design) each (X-arrangement). This arrangement permits easy mounting and safe adjustment of the bearings.
