Driving frame
In the case of locomotives for rail transport, a unit is referred to as a motor frame, which consists of a load-bearing component (mostly a steel profile frame), drive wheel sets inserted or mounted in it, and the drive ( traction motors ). Other operating equipment - such as the parts of the braking system - can be added.
Driving frames are usually assembled as a complete subassembly with other subassemblies to form a complete traction vehicle , especially if the drive wheels and traction motors are not immovably connected to the rest of the vehicle .
A "crocodile locomotive" of the SBB Be 6/8 series, for example, consists of three main parts: two coupled drive frames and a bridge with the locomotive body supported on them .
In individual cases, drive frames are used to drive trains without additional attachments or their own control equipment. See also the history of the origins of the Prussian EP 213 to EP 219 and the US traction trucks .
