GEARBOX TO MOTOR VEHICLE Russian patent published in 2013 - IPC F16H3/44 F16H59/14 

FIELD: machine building.

SUBSTANCE: gearbox includes a cylindrical helical planetary reduction gear, a carrier with satellites and their axes, a friction coupling, centrifugal weights on the coupling housing and an automatic control system of the state of a sun gear (locking, unlocking). Crown gear of planetary reduction gear is installed in a movable manner on a drive shaft, sun gear is installed freely. Carrier with satellites and their axes are fixed on a driven shaft. Drive disks of friction coupling are connected through splines to crown gear, and driven ones are connected through the coupling housing to the carrier. Automatic control system of the sun gear state includes a brake consisting of a pulley fixed on a hub of the sun gear, the brake band of which is connected through rods and two-arm levers with a spring to crown gear and two-arm control lever through a rod directly from the carrier. Gearbox has three modules so that driven shaft of the previous module is a drive shaft of the following one, which is installed after the last module of a reverse mechanism.

EFFECT: reduction of fatigability of a driver and accident risk; improving reliability of a friction coupling.
