Title:
TRAVELING/DRIVING UNIT OF WORKING VEHICLE
Document Type and Number:
Japanese Patent JP2015178322
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve a problem in a traveling/driving unit of a working vehicle operated by changing the rotation numbers of right and left traveling/driving parts that pump axis of non step hydraulic speed changer is unparallel with engine output axis of a vertically placed engine, thus a large direction changing mechanism is required to transmit driving power to the pump axis.SOLUTION: Center sections 32 are folded at least one site to form lateral extending part 32La, 32Ra and longitudinal extending parts 32Lb, 32Rb. Deceleration devices 34 are equipped on outside with interposed longitudinal extending parts 32Lb, 32Rb. Hydraulic motors 33 are equipped inside. An output shaft 16 of the deceleration device 34 and motor shaft 45 extends in lateral direction on the same criterion shaft line 52. Hydraulic pumps 31 are equipped on the lateral extending parts 32La, 32Ra. A pump shaft 35 extends in forth and back direction. Driving power is output from the output shaft 16. The pump shaft 35 may be arranged in parallel with an engine output shaft 11a. In addition, each of the hydraulic pumps 31 is constructed separately from a driving power dividing part 25.
