| description | PROBLEM TO BE SOLVED: To enable a compact configuration of a cooling fan structure capable of controlling connection/disconnection of power transmission from a crankshaft to a cooling fan in accordance with an operating state of an internal combustion engine.SOLUTION: A cooling fan structure for an internal combustion engine includes: a cooling fan 31 disposed at one end of a crankcase 13 and rotating by using power of a crankshaft 16; a flywheel 21 that is connected to one end of the crankshaft 16 to rotate together with the crankshaft 16 and is disposed adjacent to the cooling fan 31 in the axial direction of the crankshaft 16 to transmit rotating power to the cooling fan 31; and a connection/disconnection mechanism 35 for connecting/disconnecting the cooling fan 31 and the flywheel 21 to/from each other. The cooling fan structure further includes a thermo-actuator 40 operated by sensing a temperature on the side of the crankcase 13. The operation of the thermo-actuator 40 moves the cooling fan 31 in the axial direction of the crankshaft 16, so as to connect/disconnect the cooling fan 31 and the flywheel 21 to/from each other.SELECTED DRAWING: Figure 3
【課題】内燃機関の運転状態に応じてクランク軸から冷却ファンへの動力伝達の断接を制御可能な冷却ファン構造をコンパクトに構成できるようにする。【解決手段】クランクケース１３の一側に配置され、クランク軸１６の動力によって回転する冷却ファン３１と、クランク軸１６の一端に連結されてクランク軸１６と共に回転するとともに、冷却ファン３１に対しクランク軸１６の軸方向に近接して配置されて冷却ファン３１に回転動力を伝達するフライホイール２１と、冷却ファン３１とフライホイール２１とを断続させる断続機構３５とを備えた内燃機関の冷却ファン構造において、クランクケース１３側の温度を感知して動作するサーモアクチュエータ４０を備え、サーモアクチュエータ４０の動作によって冷却ファン３１がクランク軸１６の軸方向に移動させられることで、冷却ファン３１とフライホイール２１とが断続される。【選択図】図３ |
