    摘要： A speed change control device of a working vehicle, in which a power of an engine (10) is transmitted as a driving force to wheels (60) through a modulation clutch (20), a torque converter (30) having a lockup clutch (40), and a transmission (50), comprising:
    a speed change operator (70); and
    a controller (80) that, depending on certain parameters, performs a clutch control so as to:
    cause a lockup state in which the modulation clutch (20) is engaged while the lockup clutch (40) is engaged,
    cause a lockup and modulation clutch slipping state in which the modulation clutch (20) slips while the lockup clutch (40) remains engaged,
    cause a both clutch slipping state in which both the lockup clutch (40) and the modulation clutch (20) slip, and
    cause a torque converter operation state in which the modulation clutch (20) is engaged while the lockup clutch (40) is released.

    摘要： A kickdown mechanism provides a tactile feedback to the foot of a user depressing a vehicle pedal. The kickdown mechanism has a case and a roller having a recess. The roller is engaged by movement of the pedal so as to cause the roller to travel linearly. A friction generating assembly is retained by the case and engages with the roller so as to provide a tactile feedback to the user. The friction generating assembly has a rod that is retained by the case. The rod is biased into the recess such that the pedal, when depressed, urges the roller from a first position in which the rod is located in the recess to a second position in which the rod is located outside the recess.

    摘要： The present invention relates to a method for automatically controlling a transmission of a wheel loader, and more particularly, to an automatic control method for allowing a kickdown to be automatically performed in a specific stage such as excavation operation among a plurality of operational stages in which the wheel loader performs operations, and to this end, the method includes: receiving, by a transmission control unit, various information from a sensor of a transmission; receiving, by the transmission control unit, bucket position information from a boom angle sensor; and performing an automatic kickdown transmission from shift stage 2 to shift stage 1 when the received information satisfies a predetermined condition, and when the wheel loader brakes for an excavation operation, an automatic kickdown transmission is performed according to conditions of low engine RPM, low load and low travel speed and a condition in which the position of a bucket is adjacent to the ground level, and accordingly, the excavation operation starts at the state where the transmission is shifted to the shift stage 1 in advance, thereby improving work efficiency.
