3Q-6618 8 Speed Planetary Transmission
Cat® 8-Speed Planetary Transmission with 6 Hydraulically Actuated Clutches for Utility Vehicles
Description
The planetary transmission provides the torque and speed control needed to move and operate the machine effectively over rough terrain. The transmission consists of a set of interconnected planetary gears. This configuration assembly includes a sun gear, a planetary gear, a planetary gear carrier, and a ring gear. The gears work together to achieve different speed and torque outputs. Power input to the planetary transmission comes from the engine. By changing the rotation of the input, the transmission helps achieve different output speeds.
Attributes
- Enables quick shifts between gears
- Six clutches enable precise gear engagement
Applications
The planetary transmission is used in underground internal combustion load-haul-dump machines to enable direction reversal, providing forward and reverse movement. This is achieved by changing the direction of rotation of the planetary gear carrier relative to the sun gear and ring gear, thereby reversing the direction of wheel motion.
