Title:
SHIFT STEERING DEVICE AND CRAWLER VEHICLE THEREWITH
Document Type and Number:
Japanese Patent JP3429959
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To shorten a vehicle width which has been lengthened since a shift steering device mounted on a crawler vehicle has a steering clutch to cut off power during super pivotal brake turn heretofore arranged between a torque converter and a transmission part.
SOLUTION: A centrifugal valve 16 is attached to the casing of the pump impeller 4a of a torque converter 4 and during super pivotal brake turn, working oil with which the torque converter is filled is temporarily discharged by a centrifugal valve and a driving force outputted from an input shaft 1 to a transmission part is cut off. In this case, a driving force from the input shaft 1 is transmitted to an output shaft 15 through the hydraulic pump 12 of a steering machine part 11, a hydraulic motor 13, and a laterally symmetrical second planetary gear train 14, and the output shaft 15 is rotated at the same speed in different directions.
