  • Vehicle for civil engineering work
    Patent number: 4184387
    Abstract: A vehicle with an engine, a torque converter, planetary gearing sets operatively connected with the torque converter, running means on either lateral side operatively connected with the respective planetary gearing set, a turning drive mechanism with two output shafts to rotate in opposite directions with each other and switching over means for selectively switching over output rotation directions of the turning drive mechanism. The turning drive mechanism takes the driving power from input side of the torque converter and transmits the power to drive either sun gear or planetary gears of the planetary gearing sets, thus to cause differential rotary speeds of the running means on one side as compared with the other side. The vehicle can thus turn very sharply when it travels at slow speed.
