Tula State University scientists have patented a new transmission for heavy haulage and quarry machinery.
The development allows the car to move in 14 different modes. The gearbox has half the number of parts compared to analogues. The Russian Ministry of Education and Science reported this in TASS.
The new development is characterized by a multi-wire planetary gear, which combines three rows of gears in one differential unit.
Unlike traditional gearboxes, in which some of the wheels rotate without participating in the transmission of power, in the new development all parts are in the network, which allows for faster gear changes, reduces brake wear and increases the service life of the unit.
