    Gear Units for any Application

      Gear units from Voith are operating all over the world. They are optimally adapted to individual customer requirements and all rail applications.


       

      Gear Units for Light Rails and Trams

      Longitudinal drive

      Bevel gears for longitudinal drive
      Arrangement fully suspended KSH-type

      The motor is located in the bogie or underneath the railcar body. The motor's shaft is at a right angle to the wheelset's shaft. It is connected to the transmission either directly, via a diaphragm coupling or via a cardan shaft. The bevel gears transmit power at an angle of 90°. The drive's output gear is mounted on a quill shaft. This gear connects to the wheelset by means of a 2-level wedge packet coupling. This provides a fully sprung arrangement.

      Transversal drive

      Helical gears for transversal drive
      Arrangement fully suspended SZH-type

      The motor is located in the bogie. It is connected to the helical gear stage by a diaphragm coupling. The motor's shaft is parallel to the wheelset's shaft. The drive's output gear is mounted on a quill shaft. This gear connects to the wheelset by means of a 2-level wedge packet coupling. This provides a fully sprung arrangement.

      Gear Units for Metros

      Transversal drive

      Helical gear SE-type with one stage
      Axle mounted

      The motor is located in the bogie. The motor's shaft is parallel to the wheelset's shaft. A bow-tooth coupling transmits power to the helical gears of the helical gear stage. This stage compensates for the relative motion between the bogie and the wheelset's shaft.

      Transversal drive

      Helical gear SZ-type with two stages, axle mounted

      The motor is located in the bogie. The motor's shaft is parallel to the wheelset's shaft. A bow-tooth coupling transmits power to the helical gears of the helical gear stage. This stage compensates for the relative motion between the bogie and the wheelset's shaft.

      Longitudinal drive

      Bevel gear KE-type with one stage, axle mounted

      The electric motor or turbo transmission is located outside the bogie beneath the railcar body. The motor's shaft is at a right angle to the wheelset's shaft. A cardan shaft transmits power to the bevel gear stage. The bevel gears transmit power at an angle of 90°. The cardan shaft compensates for the relative motion between the final drive and electric motor or turbo transmission.

      Gear Units for Diesel Locomotives

      Transversal drive

      Helical gear SET-type in connon-box design with one stage, axle mounted

       

      The motor is located in the bogie. The motor's shaft is parallel to the wheelset's shaft. Motor and transmission are housed in the same case. The output pinion is mounted directly on the motor's shaft. It meshes with the large helical output gear. There is no coupling element between the input (motor) and output (wheelset).
