THROUGH MAIN TRANSMISSION Russian patent published in 2019 - IPC B60K17/16 

FIELD: transport machine building.

SUBSTANCE: invention relates to a through main transmission of multiaxial all-wheeled vehicles. Passage main gear comprises reduction gear casing, interaxle and inter-wheel differentials, cylindrical and conical driven gears and drive gears. Carter of reducer is made in the form of cylindrical first shells conjugated into single housing and provided with oil channels and second and additional shells arranged together. In the lower part of the first shell a plunger pump is installed. First cylindrical gear and the interaxle differential are aligned with the feedthrough drive shaft in the casing of the second casing of the reduction gear case. Second cylindrical gear is located on the shaft of the drive bevel gear fixed in the casing of the additional casing of the reduction gear casing. Shaft of drive conical gear is installed parallel to shaft of interaxle differential and second cylindrical gear is made with possibility of constant engagement with first cylindrical gear. Interaxle differential is equipped with a blocking device. Driven bevel gear and cross-axle differential gear are aligned in case of first casing of reduction gear casing. Driven bevel gear constantly engages with drive bevel gear.

EFFECT: higher reliability and compactness of main through transmission.
