FIELD: mechanical engineering.
SUBSTANCE: invention relates to a coaxial three-shaft eight-stage reversible transfer case. The transfer case contains the primary and secondary shafts, parallel to them is the drive shaft of the front axle. Between the parallel shafts there are four pairs of gears and three switching clutches: two three-position and one double with oppositely deployed clutches interconnected by a common switching fork. A conical reverse gearbox is attached to the front wall of the housing at the input of the primary shaft, an inter-bridge differential with a lock is installed at the output of the secondary shaft.
EFFECT: increased reliability, reduced dimensions and metal consumption of the transfer case are achieved.
