Abstract

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。

Description

一种传动轴支架
技术领域
本发明涉及汽车零部件的领域，具体涉及一种传动轴支架。
背景技术
传动轴支架典型结构由外壳、橡胶垫、轴承构成。外壳与车辆底盘连接，传动轴主体与轴承连接，橡胶垫包裹轴承，起到支撑传动轴主体及吸收传动轴振动作用。现有结构中橡胶垫采用等刚度设计及制造，在360°方向上的刚度均等。而根据实际需求而言，位于下方的橡胶刚度应大，便于支撑传动轴主体，而位于上方的橡胶刚度应小，便于吸收振动。
发明内容
本发明的目的在于克服现有技术存在的不足，而提供一种传动轴支架，解决了现有传动轴支架结构的减震缺点，又满足了功能需求。
本发明的目的是通过如下技术方案来完成的：这种传动轴支架，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。
作为优选的技术方案，所述飞翼结构之间所呈夹角为120°。
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。
附图说明
图1为本发明的结构示意图。
附图标记说明：外壳1、橡胶垫2、轴承3、装车方向4、飞翼结构5、高刚度区域6。
具体实施方式
下面将结合附图对本发明做详细的介绍：
实施例：如附图所示，这种传动轴支架，包括外壳1、橡胶垫2和轴承3，所述外壳1以装车方向4与车辆底盘连接固定，外壳1内设有轴承3，传动轴主体套入轴承3内，轴承3外周包裹有橡胶垫2，橡胶垫2与外壳1内壁之间采用间隙配合；橡胶垫2外周背离装车方向4的一侧对称设置有飞翼结构5，飞翼结构5与外壳1内壁之间采用过盈配合，从而在背离装车方向4一侧的橡胶垫2上形成高刚度区域6。
优选的，所述飞翼结构5之间所呈夹角为120°。
本发明相比原有支架，在原支架下方的橡胶垫上新增飞翼结构，橡胶飞翼接触到外壳时，下方位置变为高刚度，而对应的上部无飞翼结构，仍然为原来的低刚度。使得橡胶垫在360°方向上的刚度不均等，位于下方的橡胶刚度大便于支撑传动轴主体，而位于上方的橡胶刚度小，便于吸收传动轴的振动。
可以理解的是，对本领域技术人员来说，对本发明的技术方案及发明构思加以等同替换或改变都应属于本发明所附的权利要求的保护范围。
