The invention discloses an intermediate transmission shaft assembly which comprises a connecting shaft, a dustproof cover and a support. The connecting shaft consists of a differential end spline shaft, a hollow pipe and a transmission shaft end spline shaft, two ends of the hollow pipe are welded with the differential end spline shaft and the transmission shaft end spline shaft respectively, thedifferential end spline shaft is matched and connected with a differential spline, and the transmission shaft end spline shaft is matched and connected with a transmission shaft assembly internal spline; the dustproof cover is arranged on the connecting shaft and is in interference fit with the connecting shaft; a bracket is connected with the connecting shaft through a bearing; and a middle shafttransmission shaft assembly and a right transmission shaft assembly (or a left transmission shaft assembly) are limited through a connecting clamp spring. The transmission shaft assembly is light inweight, an excitation frequency of excitation sources such as an engine and the like can be avoided, NVH quality of the whole vehicle is improved, the problem that lubricating grease in the bearing slightly leaks to generate oil stains to influence the appearance quality is solved, and meanwhile a service life and a wading capacity of the bearing can be prolonged and improved.

    本发明公开了一种中间传动轴总成,包括连接轴、防尘盖、支架;连接轴由差速器端花键轴、空心管和传动轴端花键轴组成,空心管两端分别与差速器端花键轴及传动轴端花键轴焊接,差速器端花键轴与差速器花键配合连接,传动轴端花键轴与传动轴总成内花键配合连接;防尘盖安装在所述连接轴上,两者为过盈配合;支架与连接轴通过轴承连接;中间轴传动轴总成和右传动轴总成(或左传动轴总成)通过连接卡簧限位。本发明重量轻,可以避开发动机等激励源的激振频率,提升整车NVH品质,避免轴承内润滑脂轻微渗漏产生油迹影响外观品质问题,同时可以提高轴承的寿命和涉水能力。
