Two stage planetary final device

摘要

A compact final drive assembly comprises a stationary housing and a rotatable housing. A bent axis hydraulic motor is coupled to the stationary housing. The bent axis hydraulic motor drives a planetary drive unit for driving the rotatable housing. A clutch/brake unit controls the planetary drive unit by braking the planet carrier. The clutch/brake unit is provided with a ring piston that is supplied pressurized hydraulic fluid from the motor inlet port of the bent axis hydraulic motor.
