The invention discloses a transmission shaft support and relates to the field of automobile parts. The transmission shaft support comprises a shell, a rubber pad and a bearing, the shell is fixedly connected with a vehicle chassis in the loading direction, the bearing is arranged in the shell, a transmission shaft body is sleeved with the bearing, the periphery of the bearing is wrapped with the rubber pad, and the rubber pad is in clearance fit with the inner wall of the shell; and flying wing structures are symmetrically arranged on the side, away from the loading direction, of the periphery of the rubber pad, and the flying wing structures are in interference fit with the inner wall of the shell, so that a high-rigidity area is formed on the side, away from the loading direction, of the rubber pad. The transmission shaft supporthas the beneficial effects that: the rubber pad is designed to be asymmetric in rigidity, the requirement for supporting the transmission shaft body is met, and the damping NVH performance is also improved.
本发明公开了一种传动轴支架,涉及汽车零部件领域,包括外壳、橡胶垫和轴承,所述外壳以装车方向与车辆底盘连接固定,外壳内设有轴承,传动轴主体套入轴承内,轴承外周包裹有橡胶垫,橡胶垫与外壳内壁之间采用间隙配合;橡胶垫外周背离装车方向的一侧对称设置有飞翼结构,飞翼结构与外壳内壁之间采用过盈配合,从而在背离装车方向一侧的橡胶垫上形成高刚度区域。本发明的有益效果为:通过将橡胶垫设计为非对称刚度,不仅满足了传动轴主体支撑的需求,也提升了减震NVH性能。
