The invention relates to the technical field of automobile transmission shafts and particularly relates to an inflatable transmission shaft intermediate support device. The support device comprises an upper support, a rubber component, a dustproof component, a bearing, a lower support and an inflation inlet, wherein an outer ring of the rubber component wraps a ring-shaped support formed by folding an upper support and a lower support, a lug part is arranged at a joint of the upper support and the lower support, and corresponding mounting holes are formed in the lug part of the upper support and the lug part of the lower support and used for being fixed to a vehicle body mounting position; a bearing is mounted on an inner ring of the rubber component; a dustproof component is mounted between a rubber component inner ring and a bearing outer ring; the rubber component is an annular air bag made of rubber, and metal wires or metal wire meshes are embedded in a rubber layer of the annular air bag; the inflation inlet is connected with the rubber part and extends out of a through hole formed in the upper support or the lower support, and the annular air bag is inflated through the inflation inlet. The support device can bear large air pressure, the pressure adjusting range of the air bag is enlarged, and therefore radial rigidity of the support assembly is increased, and the driving comfort of the whole vehicle is improved.

    本发明涉及汽车传动轴技术领域,尤其是一种充气式传动轴中间支承装置,包括上支架、橡胶部件、防尘部件、轴承、下支架和充气口;橡胶部件外圈包裹着由上支架和下支架合拢形成的圈状支架,上支架和下支架连接处制有耳部,且上支架和下支架耳部开设有对应的安装孔,用于固定在车身安装位置;橡胶部件内圈安装有轴承;橡胶部件内圈和轴承外环之间安装有防尘部件;橡胶部件为橡胶制作的环状气囊,环状气囊的橡胶层内嵌入有金属丝或金属丝网;充气口与橡胶部件连接并且从上支架或下支架开设的通孔伸出,通过充气口给环状气囊充气。该支承装置能够承受较大的气压,扩大气囊调节压力的范围,从而增大支承总成的径向刚度,提高整车行驶舒适性。
