VEHICLE DRIVE AND ITS PRODUCTION METHOD Russian patent published in 2008 - IPC B61C9/38 

FIELD: transport.

SUBSTANCE: invention relates to the vehicle drive devices, primary electric vehicle of rail ways. Electric drive of vehicle contains electric motor hung to the frame, on which axis drive gear is fixed, engaging with follower gear, hard mounted on wheel set axis. Gearwheels, creating gear head, are located in frame, which is fixed to the vehicle frame with spring linkage and made with slanting teeth, which lap is near to two. At that gear box is made with walls of different thickness. While producing of towing drive the number of teeth and their inclination are adjusted in order that natural oscillation frequency of frame during the rotation of motor axis misalign the oscillation frequency, exerted with the drive operation on exploitation speed of electric train movement.

EFFECT: maximal amplitude of drive oscillation is decreased, the biggest of decreased have the frequencies, appearing on speed modes, which are rarely used, for example white vehicle speed-up.
