This paper presents an analysis of selected design solutions for the running gear of freight locomotives and their impact on the vehicles’ traction characteristics. The first part discusses the basic concepts related to traction properties, including the relation-ships derived from the train motion equation and the traction characteristics. Next, the design of freight locomotives and their operating conditions were described. The main section of this paper reviews the design solutions used in the running gear of modern locomotives in operation on the European market, including suspension systems, wheelset guidance, and the transmission of traction forces and torques. Their importance in ensuring adequate traction performance, driving safety, and the structural durability of the vehicle was highlighted.
The article presents the results of a comprehensive analysis of existing methods and
technical means for assessing the traction performance of tractor equipment. The technical specifications
of dynamometers used in Russian and international testing centers are provided. The research revealed
that the vast majority of f...

The transmission of traction electric motor torque to the electric locomotive wheelset is carried out through a wheelset reducer with cylindrical gears with straight or inclined teeth. The wheelset reducer is one of the most important units of a modern electric locomotive. It bears significant alternating loads when th...
