PLANETARY GEARBOX Russian patent published in 2001 - IPC

Abstract RU 2177416 C1

FIELD: mechanical engineering; transmissions of road, earth and other vehicles. SUBSTANCE: additional friction disk with outer splines and friction disk with inner splines are installed in all friction clutches and brakes of planetary gearbox which makes t possible to increase carrying capacity of gearbox by 20-25% without changing outer overall dimensions owing to adjustment of inner axial clearances and thicknesses of parts. Mounting of pressure disk of driving unit friction clutch engagement booster onto splines of rotating drum and provision of clearances between holes in pressure disk and studs of release device precludes encounter of pressure disk and studs, loosening and breaking of studs. Axial locking of epicycle of third planetary train by means of outer ring projection of carrier makes it possible to dispense with bolted joint and defect caused by breaking of bolts and disturbance of axial locking of epicycle. EFFECT: increased carrying capacity of gearbox. 1 dwg
