After the power of the transmission is transmitted to the central transmission, it changes from longitudinal transmission to lateral transmission, and the horizontal shaft is respectively transmitted to the left and right steering clutches. The 220-horsepower and 230-horsepower steering clutches are spring-loaded, hydraulically separated, constantly meshed, and wet-type friction plates. It includes outer drum, inner drum, pressure plate, outer friction plate, inner teeth, piston, bolt, sleeve and piston are connected as a whole, large and small springs are supported on the inner drum, and the spring installation load pushes the piston to the right Move, drive the pressure plate to press the friction plate and the gear plate together, and realize the joint force transmission. There are 8 sets of springs with a total installed load of 3.2T. There is enough pressure to compress the friction plate to transmit torque.
When the crawler bulldozer needs to turn (such as pulling the left steering rod), the hydraulic oil is filled into the oil cavity between the steering clutch piston and the hub. The oil pressure pushes the piston and drives the pressure plate to move to the left. The friction plate and gear plate are loosened. Then the torque is transmitted, the left side of the crawler bulldozer loses power, and it turns to the left under the push of the right crawler. At the end of the steering, the pull rod is released, the hydraulic oil returns under the push of the piston, the steering clutch is re-engaged to transmit force, and the crawler bulldozer resumes straight travel.
