Abstract

The gearbox is part of the powertrain that transmits movement from the engine to the wheels. Gears, shafts and auxil-iary systems are used in Gearboxes. By using these systems, it is possible to control the movement of the vehicle at the desired tractive effort and vehicle speed in different gear ratios as well as in different direction situations. To increase vehicle performance, it is necessary to obtain curves close to the ideal traction hyperbola.

In this study, vehicle speed and tractive efforts of two different 12-speed vehicles with the same engine characteristics were calculated with Matlab/Simulink. According to obtaining the results, the tractive effort curves based on vehicle speed were estimated and ideal traction hyperbola curves were formed. The comparison of ideal traction hyperboles for both types of gearboxes showed that the curves have a similar structure.
