FIELD: machine building.
SUBSTANCE: invention refers to multi-speed transmission with double coupling. Transmission is connected to the inlet element of the motor and has outlet distribution mechanism, first and second inlet transmission shafts, first and second intermediate shafts, multiple coplanar set of gears and multiple devices transmitting torsion torque. First and second inlet transmission shafts are supported so that they could rotate in the transmission body with combination of ball and needle bearings. First and second inlet transmission shafts are supported so that they could rotate in the transmission body with multiple support bearings. The devices transmitting the torsion torque include many synchronizing units and double coupling unit. Transmission ensures at least one advantage of back run and many advantages of fore run between inlet and outlet elements.
EFFECT: improvement of multi-stage transmission arrangement.
