●　Two-stage decelerating mechanism is adopted for the drive axle.the spiral bevel gear deceleration and wheel planetary reduction mechanism,input torque,high transmission efficiency.

●　The brake in enclosed multi-disc wet-type baking mode,with braking hub,hydraulic pressing,spring release and excellent braking performance,is installed behind the planetary hub decelerating-gears.

●　The drive axle is with small tread,wheel track,wheel tread,applicable for underground equipments such as underground carry-scraper.
