The invention discloses a liquid filling type transmission shaft intermediate supporting device, and relates to the field of automobile transmission shafts, the liquid filling type transmission shaft intermediate supporting device comprises an upper support, a rubber part, a dustproof part, a bearing, a lower support and an oil injection port, the outer ring of the rubber part wraps the upper support and the lower support respectively, and the upper support and the lower support are of symmetrical semicircular shell structures; a support lug is arranged at the joint of the two parts and is fixed at the mounting position of a vehicle body; a bearing is mounted on the inner ring of the rubber part; an annular air bag is formed between an inner ring and an outer ring of the rubber component, an oil filling port arranged on the rubber component is communicated with the annular air bag, and hydraulic oil is filled into the annular air bag through the oil filling port. The air bag has the beneficial effects that the metal wires are additionally arranged in the rubber layer of the air bag, the bearable pressure of the rubber layer is improved, and the pressure adjusting range of the air bag is expanded; and the pressure of the hydraulic oil is far greater than 0.8 Mpa, and the hydraulic oil is filled into the rubber part, so that the radial rigidity of the bearing assembly is increased, and the driving comfort of the whole vehicle is improved.
本发明公开了一种充液式传动轴中间支承装置,涉及汽车传动轴领域,包括上支架、橡胶部件、防尘部件、轴承、下支架和注油口,所述橡胶部件的外圈分别包裹上支架和下支架,上支架和下支架为相互对称的半圆形壳体结构,在二者的连接处设置支耳,用于固定在车身的安装位置;所述橡胶部件的内圈安装有轴承;橡胶部件的内圈与外圈之间形成环状气囊,设置在橡胶部件上的注油口与所述环状气囊相连通,通过注油口给环状气囊充注液压油。本发明的有益效果为:在气囊的橡胶层中增加金属丝,提高橡胶层可承受的压力,扩大气囊调节压力的范围;液压油的压力远大于0.8Mpa,给橡胶部件充液压油,从而增大支承总成的径向刚度,提高整车行驶舒适性。
