PROBLEM TO BE SOLVED: To provide a hydraulic clutch device that can finely and accurately control torque even at a low clutch operating oil pressure by avoiding an influence of a centrifugal oil pressure associated with high speed rotation in a large hydraulic clutch.SOLUTION: A hydraulic clutch device comprises a first shaft, a second shaft disposed coaxially with the first shaft, a friction transmission mechanism that is disposed between the first shaft and the second shaft and transmits rotational power by friction force or the viscous resistance of oil, and a hydraulic pressing mechanism that rotates together with the first shaft or the second shaft and presses the friction transmission mechanism in an axial direction to change the power transmission torque of the friction transmission mechanism. The hydraulic pressing mechanism has a piston reciprocating in the axial direction to press the friction transmission mechanism, a cylinder accommodating the piston, a first pressure space that is formed between the piston and the cylinder and applies a hydraulic pressure to the piston, and a second pressure space that is formed between the piston and the cylinder and applies a hydraulic pressure to the piston.SELECTED DRAWING: Figure 1

    【課題】本発明は、大型油圧クラッチにおいて、高速回転に伴う遠心油圧による影響を避け、低圧のクラッチ作動油圧でもトルクを細かく高精度に制御可能な油圧クラッチ装置を提供する。【解決手段】第一軸と、第一軸と同軸状に配置される第二軸と、第一軸と第二軸の間に配置されて、摩擦力又は油の粘性抵抗によって回転動力を伝達する摩擦伝達機構と、第一軸又は第二軸と共に回動し、摩擦伝達機構を軸方向に押圧して、該摩擦伝達機構の動力伝達トルクを変化させる油圧押圧機構を備え、油圧押圧機構は、軸方向に往復移動して摩擦伝達機構を押圧するピストンと、ピストンを収容するシリンダと、ピストンとシリンダの間に形成されて、ピストンに油圧を印加する第一圧力空間と、ピストンとシリンダの間に形成されて、ピストンに油圧を印加する第二圧力空間を有することを特徴とする油圧クラッチ装置。【選択図】図1
