The invention relates to the technical field of engineering machinery, and discloses a power transmission system and an engineering vehicle. The clutch is arranged corresponding to the output end of the power component and has a combined state and a separated state with the power component; the transmission assistance mechanism enables the clutch to be switched between a combined state and a separated state; and the blowing mechanism is in transmission connection with the transmission assistance mechanism so as to be in linkage with the clutch, the blowing mechanism is in a blowing state when the clutch is in a separation state, and the blowing mechanism is in a closing state when the clutch is in a combination state. When the clutch is separated from the power part, air is blown to the clutch through the air blowing mechanism, so that the temperature of the clutch is reduced, abrasive dust on the clutch is blown away, the service life of a power transmission system is prolonged, and the reliability of the power transmission system is improved; moreover, when the clutch is switched between the combined state and the separated state, the blowing mechanism is switched between the closed state and the blowing state, and the overall structure is simple and reliable.

    本发明涉及工程机械技术领域,公开了动力传动系统及工程车辆,包括:动力部件;离合器,对应动力部件的输出端设置,具有与动力部件的结合状态与分离状态;传递助力机构,使离合器在结合状态和分离状态进行切换;吹气机构,与传递助力机构传动连接,以与离合器联动设置,离合器处于分离状态时吹气机构处于吹气状态,离合器处于结合状态时吹气机构处于关闭状态。本发明在离合器与动力部件分离时,通过吹气机构向离合器进行吹气,从而降低离合器的温度,并且将离合器上的磨屑吹走,提高动力传动系统的使用寿命以及可靠性;并且,在离合器在结合状态和分离状态切换时,吹气机构在关闭状态和吹气状态进行切换,整体结构简单可靠。
