Description
本发明涉及汽车前悬架***的转向节领域,更确切地说,是一种适用于直线平移式前悬架的转向节连接件总成。
现在市场中的乘用车尤其是中高级轿车的悬架多采用多连杆式独立悬架,配合使用的转向节是悬架结构中关键的零部件之一,其主要作用是连接多连杆独立悬架各导向杆支链、减振器、制动卡钳和轮毂轴承。
目前常规的多连杆式悬架等独立悬架虽然在功能上都能够满足悬架设计要求,但是当车轮跳动时,车轮定位参数均会变化。如何能够保证车轮跳动时车轮的定位参数不会发生变化是独立悬架结构创新设计中的一个重点和难点。针对这个问题,我司发明了一种可以用于汽车独立悬架***的空间多连杆直线平移式悬架,参见【1.资小林、赵景山、张杰、刘向、邱宝象、冯之敬,一种带有3-RRR伸缩补偿机构的多连杆直线导引独立悬架:中国,CN102358121A,2012.02.22。2.张杰、赵景山、资小林、刘向、邱宝象、冯之敬,一种采用滚珠花键副的多连杆直线平移式悬架:中国,CN102627061A,2012.08.08】,这种悬架机构能够使车轮的外倾角、主销内倾角和后倾角、左右轮距、车轮前束后束以及前后轴距在车轮上下跳动过程中基本保持不变,从而提高汽车的操纵稳定性、行驶平顺性以及乘坐的舒适性,并能够有效降低轮胎的磨损。同时,在具有较强的可实施性的前提下,能够保证该悬架机构具有较大各向刚度,尽可能减小受载变形。针对该型悬架在汽车后悬架中的应用,我司还发明了适用于直线平移式后悬架的转向节,参见【张杰、刘向、谌文思、王建宜、资小林、赵景山,一种用于空间多连杆直线导引式悬架的转向节:中国,CN102556158A,2012.07.11】。但是上述提及的转向节不具备转向功能,不适用于前悬架***;除此之外,目前市场上常用的转向节也并不能与新型的直线平移式悬架相匹配,无法实现悬架机构各支链与轮毂单元的顺利连接。因此需要设计适用于该种直线平移式前悬架的转向节新结构。
