WHEEL TYPE WORK VEHICLE
To provide a wheel type work vehicle capable of reducing pitching vibration caused in the work vehicle regardless of the existence of operation of an operator.SOLUTION: In a wheel loader 100 having a vehicle body 1 having an implement 3 having a front wheel 2a and a rear wheel 2b and placing a loading cargo in a front part and a vehicle control device 50, the vehicle control device 50 controls at least one of braking force and driving force to the front wheel 2a and the rear wheel 2b in response to a pitching vibration amount by extracting the pitching vibration amount being the same in frequency as a natural frequency among a vibration amount on vibration caused in the vehicle body 1 by calculating the natural frequency in the pitching direction of the vehicle body 1 changing in response to a load of the loading cargo.SELECTED DRAWING: Figure 2
【課題】操作者の操作の有無にかかわらず、作業車両に生じたピッチング振動を低減することが可能なホイール式の作業車両を提供する。【解決手段】前輪２ａおよび後輪２ｂを有すると共に前部に積荷を積載する作業機３を有する車体１と、車両制御装置５０と、を備えたホイールローダ１００であって、車両制御装置５０は、積荷の荷重に応じて変化する車体１のピッチング方向の固有振動数を算出し、車体１に生じている振動についての振動量のうち、固有振動数と振動数が同じであるピッチング振動量を抽出し、ピッチング振動量に応じて前輪２ａおよび後輪２ｂに対する制動力および駆動力の少なくとも一方を制御する。【選択図】図２
