AUTOMATIC GEARBOX FOR THE VEHICLE Russian patent published in 2017 - IPC F16H57/33 F16H3/44 F16H37/02 F16H59/10 

FIELD: transportation.

SUBSTANCE: automatic transmission of the vehicle contains four series-connected planetary gear sets, the automatic switching system and the automatic control system of the sun gear state (ACSSGS). The automatic changeover system includes the friction multi-disc clutch (FMPC), the driving disks of which are connected to the KG, and the driven ones - through the clutch body - with the carrier, the centrifugal weights, which shoulders rest against the left end of the KG. The automatic control system (ACSSGS) contains the brake, consisting of the disc clutch, the body of which is connected to SG, the driving and driven discs are connected to the clutch body and the fixed tubular axle (TA), the shift ring of which is connected to KG, and - to the control lever from the driver, it has four series-connected planetary gears with MPC with loads and the ACSSGS - four modules and the reverse mechanism, containing the pinion gear at the driven shaft of the fourth module (FM), the driven gear with internal teeth on the reverse shaft, with the gear rim and the brake band (BB) at the TA of the disc clutch FM and BB at the MPC FM casing, forming the brake with this casing, and the BB of this brake and pulley TA FM and the reverse driven gear connected to the reversing lever.

EFFECT: design simplification, increase of the reliability and the costs reduction.
