POWER TRANSMISSION DEVICE FOR WORK VEHICLE

摘要

PROBLEM TO BE SOLVED: To solve a problem of an operational delay generated when adjusting the number of revolutions of driving wheels in order to straightly advance a vehicle against a rapidly changing land shape or workload in particular in a work vehicle traveling by adjusting the number of revolutions separately for each of the right and left driving wheels. SOLUTION: The work vehicle is equipped with a pair of left and right front wheels 1F and a pair of right and left rear wheels 1R and drives the front and rear wheels with electric motors 2, 3L and 3R. In this case, the motors 3L and 3R are internally mounted in a case supporting the front wheels 1F or the rear wheels 1R by a supporting shaft. Revolutions of left and right motor output shafts 43 and 43 are connected to a clutching mechanism 6 through deceleration gears 5A and 5B respectively. Further, the revolutions of the both shafts 43 and 43 are integrated.
