Description

一种梯形液压悬置
技术领域
本发明涉及属于汽车零部件领域，尤其是一种梯形液压悬置系统。
背景技术
如今，汽车的噪声与振动的控制一直是困扰着人们的难题，严重影响着乘坐舒适性。为此人们设计了发动机悬置，通过橡胶隔离振动的传递。发动机悬置从发展至今经历了许多变革，从纯胶悬置到节流孔液压悬置，到环形流道加解耦膜液压悬置，到半主动悬置以及主动悬置。半主动悬置和主动悬置在低频时能够提供能够提供较大的阻尼和刚度，高频时能够提供较小的阻尼和刚度，减振性能较好，但由于其结构复杂，成本较高，应用不广泛。普通液压悬置虽然仅在低频内减振功能较好，在高频时由于解耦膜的作用，也可以避免高频动态硬化的现象，因此普通液压悬置得到了较为广泛的应用。
梯形液压悬置有着其独特的减振特性，可以在Z向及X向提供较大的刚度，在Y向提供较小的刚度，满足横置发动机动力总成解耦匹配的三向动、静刚度匹配的需求。目前梯形液压悬置结构上下支架多采用铸铝制造，成本较高，不利于汽车行业内普遍的降本需求。对此需要寻求一种成型较为简单，成本较低的悬置结构。
发明内容
为了解决上述问题，本发明提出了一种结构简单，加工容易，成本较低、隔振效果较好的梯形结构发动机液压悬置。
本发明的技术方案如下：一种梯形液压悬置，包括：上支架、内芯、橡胶主簧本体、主簧支撑骨架、流道组件、解耦膜、皮碗以及下支撑板，橡胶主簧本体由内芯与主簧支撑骨架通过橡胶硫化形成，下支撑板上设有拉深凸起，上支架与下支撑板贴合处设有装配孔，橡胶主簧本体以及流道组件过盈压装在上支架与下支撑板之间，橡胶主簧本体与皮碗之间形成一个密闭的液腔，流道组件将液腔分隔为上液腔及下液腔，流道组件分为流道盖板及流道板，流道盖板紧贴在主簧支撑骨架的中部，主簧支撑骨架底部与流道板底部与皮碗贴紧，流道盖板上设有进液口、流道板上设有环形流道以及出液口，该环形流道将进液口与出液口联通，环形流道将上液腔和下液腔联通，解耦膜置于流道盖板及流道板之间，橡胶主簧本体、主簧支撑骨架以及流道板上设有灌液孔。
进一步地，上支架与下支撑板为冲压件，上支架与下支撑板两端翻边，下支撑板通过凸起插入装配孔内。
进一步地，橡胶主簧本体X、Y、Z三个方向设有限位垫。
进一步地，主簧支撑骨架为铸铝件或塑料件。
进一步地，皮碗与下支撑板通过橡胶硫化为一体，或皮碗单独成型。
进一步地，皮碗上在该贴紧处设有密封筋。
本发明的有益之处在于：本发明中悬置主簧在X、Y、Z三个方向设有限位垫，可以满足该三个方向的线性段及非线性段的需求，上支架与下支撑板为冲压件，该冲压件结构强度较同等质量的铸铝件强，且生产效率要高，成本较低，易于成型，在低频时能够提供较大的刚度和阻尼，在高频时能够避免高频动态硬化，结构简单，加工容易，成本较低、隔振效果较好。

具体实施方式
下面结合附图对本发明做进一步详述。
一种梯形液压悬置，包括：上支架（1）、内芯（2）、橡胶主簧本体（3）、主簧支撑骨架（4）、流道组件、解耦膜（10）、皮碗（13）以及下支撑板（8），橡胶主簧本体由内芯（2）与主簧支撑骨架（4）通过橡胶硫化形成，主簧支撑骨架（4）为铸铝件或塑料件，满足强度，且降低成本，上支架（1）与下支撑板（8）为冲压件，下支撑板（8）上设有拉深凸起，上支架（1）与下支撑板（8）贴合处设有装配孔（81），上支架（1）与下支撑板（8）两端翻边，加强结构强度，下支撑板（8）通过凸起插入装配孔内，从该凸起上部进行扩孔，则实现铆接，该冲压件结构强度较同等质量的铸铝件强，且生产效率要高，橡胶主簧本体（3）以及流道组件过盈压装在上支架（1）与下支撑板（8）之间，橡胶主簧本体（3）与皮碗（13）之间形成一个密闭的液腔，流道组件将液腔分隔为上液腔（9）及下液腔（12），流道组件分为流道盖板（6）及流道板（7），流道盖板（6）紧贴在主簧支撑骨架（4）的中部，主簧支撑骨架（4）底部与流道板（7）底部与皮碗（13）贴紧，皮碗（13）上在该贴紧处设有密封筋，皮碗（13）与下支撑板（8）通过橡胶硫化为一体，或皮碗单独成型，并在装配时贴合压紧在下支撑板上，流道盖板（6）上设有进液口（61）、流道板（7）上设有环形流道（11）以及出液口（71），该环形流道（11）将进液口（61）与出液口（71）联通，环形流道将上液腔（9）和下液腔（12）联通，解耦膜（10）置于流道盖板（6）及流道板（7）之间，橡胶主簧本体（3）、主簧支撑骨架（4）以及流道板（7）上设有灌液孔，抽真空干灌后，将密封钢珠过盈压装在主簧支撑骨架的灌液孔（15）内，实现密封。
橡胶主簧本体（3）X、Y、Z三个方向设有限位垫，可以满足该三个方向的线性段及非线性段的需求。
本发明的装配过程为：先将解耦膜放（10）置于流道盖板（6）及流道板（7）之间，压入主簧内，将皮碗（13）盖在下支撑板（8）的凹槽内，再将上支架（1）及主簧压入到下支撑板（8）上，进行铆接，装配后通过主簧上的灌液孔进行抽真空干灌，最后压入钢珠进行过盈密封。
该悬置的工作方式为：内芯（2）中插入与发动机连接的支臂，发动机的激励传递到支臂上，带动主簧上下运动，主簧变形，使上、下液腔（12）内的液体在流道间来回窜动，在低频大振幅时产生较大的动刚度和阻尼。在高频小振幅时，通过解耦膜（10）变形补偿主簧变形量，缓解高频动态硬化。因此，振动被衰减。
