POWER DISTRIBUTION MECHANISM OF THE VEHICLE TRANSMISSION SYSTEM Russian patent published in 2017 - IPC B60K17/35 F16H48/30 F16H37/08 

FIELD: automobile production.

SUBSTANCE: power distribution mechanism (PDM) in a vehicle transmission system includes two-stage reduction gear system. PDM input link is indirectly connected to the engine, and the output links are indirectly connected, for example, through the semi-axles, with drive wheels of the vehicle. Three planetary gear rows - zero, the first and the second are included into PDM. The zero row, directly related to the mentioned input link, is the simple differential. There the brake elements T₁ and T₂ are provided with differential braking effect on the gear system links and the electronic control system of the mentioned braking elements, connected to the steering gear with the ability to turn the steering wheels of the vehicle. The gear part is formed with three cylindrical three-links planetary gear rows. Its input link is connected to the links, at least of two planetary gear rows. The brake elements control system is made using the principle of pulse width modulation of pressure in the friction contact pairs of braking elements.

EFFECT: increase of technical-operational or tactical-technical characteristics.
