The invention discloses a transmission shaft supporting device for an automobile, which comprises a transmission shaft body; a supporting bearing and an efficient protection gas transmission mechanism are arranged outside the transmission shaft body; an intermittent face rotating mechanism is arranged in the efficient protection gas transmission mechanism; a hard object buffering protection mechanism is arranged outside the supporting bearing; the efficient protection air transmission mechanism comprises a circular cavity sleeve plate; the intermittent face rotating mechanism comprises an inclination adjusting component and an original state recovery component; and the inclination adjusting component comprises an adjusting cavity, a twisting rod and a center rotating rod. According to the transmission shaft supporting device for the automobile provided by the invention, by means of the efficient protection gas transmission mechanism, when the transmission shaft rotates, air conveying rotating blades rotate at a high speed, the supporting bearing can be cooled in real time, mud splashed into the supporting bearing can be scattered, impact force generated when the air conveying rotating blades make contact with hard stones in the mud can be effectively buffered through a hard object buffering protection mechanism and an elastic face gauze element, the inclination of the air conveying rotating blades can be adjusted through the intermittent face rotating mechanism, and the hitting face of the air conveying rotating blades to the mud is increased.

    本发明公开了一种汽车用传动轴支撑装置,包括传动轴主体,传动轴主体的外部设置有支撑轴承和高效防护输气机构,高效防护输气机构的内部设置有间隙性转面机构,支撑轴承的外部设置有坚硬物缓冲防护机构,高效防护输气机构包括圆形空腔套板,间隙性转面机构包括斜度调节部件和原状态恢复部件,斜度调节部件包括调节腔、设扭动杆以及中心转杆,本发明通过高效防护输气机构,在传动轴转动时输风转叶高速转动,可实时冷却支撑轴承内部,并可打散向支撑轴承内部飞溅来的泥渍,通过坚硬物缓冲防护机构,弹性面纱网可有效缓冲与泥渍中坚硬石块接触时产生的冲击力,通过间隙性转面机构,可对输风转叶进行斜度调节,增大输风转叶对泥渍的打击面。
