THROUGH FINAL DRIVE Russian patent published in 2001 - IPC

FIELD: mechanical engineering. SUBSTANCE: proposed through final drive has reduction gear housing with fitted-on cover, additional housing arranged in between, and forward-rear axle drive cylindrical gear installed on antifriction bearings. Inner races of these bearings are press-fitted on cylindrical gear, and outer races are arranged in additional housing and in cover of reduction gear housing. Drive shaft of final drive passes through cylindrical gear of forward-rear axle drive with bearing supports on ends and through interaxle bevel differential with rear and forward-rear drive bevel gears installed on drive shaft. Bevel gears of rear and forward-rear axle drives thrust against end face surface of cross of interaxle differential. Bevel gear of forward-rear axle drive is made integral with cylindrical gear installed on radial antifriction bearings. Radial0thrust bearings are installed for use as bearing support on input end of drive shaft and on bevel gear of rear axle drive. Additional housing is made separately from cup of bearings of driving bevel gear. EFFECT: simplified adjustment of final drive. 1 dwg
