The article considers the problem of extension of configuration and operation characteristics of the land transport vehicles due to the simplification of the structure of the speed variator, implementation of capabilities of the planetary gear while transforming and transmitting the torsion torque in various working modes without the interruption in torque delivery and at the shutdown of the variator. The kinematic diagrams of the continuously variable transmission with a frontal variablespeed friction drive unit and a simple three-link planetary gear in the mode "a+h" with a parallel and perpendicular location of input and output shafts were provided. The work of the planetary gear in various modes was described: the gear and cumulative mode without the interruption in torque delivery and during the shutdown of the variator. The technical and economic assessment of the use of the continuously variable transmission with a planetary gear "a+h" was provided..
