The invention discloses an automobile driving shaft buffer connecting arm, and relates to the technical field of automobile parts, the automobile driving shaft buffer connecting arm comprises a driving shaft, one end of the driving shaft is connected with the output end of an engine of an automobile, the connecting arm is connected with the other end of the driving shaft, a buffer spring is arranged at the butt joint of the driving shaft and the connecting arm, and an air pressure cavity is formed in the connecting arm; the driving shaft is used for counteracting acting force applied by the driving shaft to the connecting arm, and a rotating piece is arranged at the movable end of the driving shaft and the connecting arm; the load of the buffer spring is reduced, the buffer spring is protected in the long-time use process, the service life of the buffer spring is prolonged, the air pressure cavity can generate self-adaptive change according to the motion state of the driving shaft and the connecting arm, it is guaranteed that the relative motion of the driving shaft and the connecting arm is smoother, and it is guaranteed that impact on the driving shaft and the connecting arm is small; the driving shaft and the connecting arm are protected, and the service life of the connecting arm of the driving shaft is prolonged.

    本发明公开了一种汽车驱动轴缓冲连接臂,涉及汽车零部件技术领域,包括驱动轴,驱动轴的一端与汽车的发动机输出端连接,连接臂与驱动轴的另一端连接,在驱动轴与连接臂的对接处设置有缓冲弹簧,连接臂的内部开设有气压腔,用于抵消驱动轴对连接臂施加的作用力,在驱动轴与连接臂的活动端设置有转动件;降低缓冲弹簧的负荷,使缓冲弹簧在长时间使用的过程中受到保护,提高了缓冲弹簧的寿命,气压腔会根据驱动轴与连接臂的运动状态产生自适应变化,保证驱动轴与连接臂相对运动更加平缓,保证驱动轴与连接臂受到的冲击小,也保护了驱动轴和连接臂,增加了驱动轴的连接臂使用寿命。
