The invention discloses a wheel resistance reduction device with active jet flow resistance reduction and passive resistance reduction, which comprises an active jet flow box, the interior of the active jet flow box is provided with a jet flow cavity and a jet flow plate, the jet flow plate is provided with a jet flow nozzle, a jet flow inlet on the active jet flow box is connected with a high-pressure air source through an air delivery pipe, and the air delivery pipe is provided with a speed regulating valve; the passive flow guide plate is fixed to the active jet flow box, a cavity is formed in the passive flow guide plate, the jet flow cavity extends into the cavity, and the jet flow plate is hinged to an opening in the bottom end of the passive flow guide plate through a first pin shaft; the jet angle adjusting mechanism is fixed to the active jet box and hinged to the jet plate through a second pin shaft; and a vehicle-mounted controller. According to the device, passive resistance reduction and active jet flow resistance reduction are organically integrated, under the condition that the vehicle speed is not high, passive resistance reduction is adopted, active jet flow resistance reduction is not needed, energy consumption of the vehicle is reduced, under the condition that the vehicle speed is high, active jet flow resistance reduction participates in resistance reduction work, the wind resistance coefficient of the vehicle is greatly reduced, and the energy efficiency and the driving performance of the vehicle are improved.
本发明公开了一种具有主动射流减阻和被动减阻的车轮减阻装置,包括:主动射流箱,其内部有射流腔和射流板,射流板上有射流喷口,主动射流箱上的射流入口通过输气管与高压气源连接,输气管上有调速阀;被动导流板,其与主动射流箱固定,被动导流板内部有空腔,射流腔延伸至空腔内部,射流板与被动导流板底端敞口处通过第一销轴铰接;喷射角度调节机构,其与主动射流箱固定,且与射流板通过第二销轴铰接;以及车载控制器。该装置将被动减阻和主动射流减阻有机整合,在车速不高的情况下,采用被动减阻,无需主动射流减阻参与,降低车辆能耗,当车速较高的情况下,主动射流减阻参与减阻工作,大大降低车辆的风阻系数,提高车辆能效和行驶性能。
