The invention provides a driving shaft assembly which comprises a shaft body; the shaft body comprises a left half shaft and a right half shaft; the left half shaft and the right half shaft slide relatively in the axial direction of the shaft body; two cavities are formed in the left half shaft and the right half shaft in a manner of penetrating through the axial direction and communicate with each other; fixed type constant velocity universal joints are arranged on the left half shaft and the right half shaft; an accommodating cavity communicating with the cavity of the left half shaft or theright half shaft is formed in each of the fixed type constant velocity universal joints; the driving shaft assembly further comprises a sealing structure; the sealing structure comprises a sleeving mounting piece arranged on the connecting part of the left half shaft and the right half shaft in a sleeving manner, and a sealing element arranged between the connecting end of the sleeving mounting piece and the right half shaft. According to the driving shaft assembly, the left half shaft and the right half shaft are in sliding fit to ensure the slippage performance of the driving shaft assembly; the cavities communicate with the accommodating cavities to ensure the air pressure in the two accommodating cavities to be always equal, so that degree resistance generated due to air lock is reduced, and the driving comfort of a vehicle is improved.

    本发明提供了一种驱动轴总成,包括轴体,其包括具有沿轴体轴向的相对滑动的左半轴和右半轴,于左半轴和右半轴内分别形成有轴向贯通布置的空腔,且两个空腔相互连通;于左半轴和右半轴上分别配置有固定式等速万向节,并于各固定式等速万向节内构造有连通所述左半轴或所述右半轴上空腔的容纳腔;还包括密封结构,其包括套设于左半轴和右半轴的连接部位的套装件,以及设于套装件的连接端和右半轴之间的密封件。本发明所述的驱动轴总成,左半轴和右半轴滑动连接可保证驱动轴总成的滑移性能,空腔和容纳腔连通,可保证两个容纳腔内气压始终相等,从而减小由于气阻产生的阶次阻力,提升车辆的驾驶舒适性。
