Description

一种后副车架衬套结构
技术领域
本发明涉及涉及一种副车架到车身的连接部件，具体涉及一种后副车架衬套结构。
背景技术
后副车架衬套是连接副车架和车身的弹性元件,副车架衬套的X,Y,Z三个方向的刚度对车辆的操作稳定性和NVH性能至关重要，汽车厂商一般要对这个三个方向的刚度进行多轮调试，以确定最优的衬套刚度。目前后副车架衬套以内骨架、橡胶和封闭式外骨架形式为主，但是封闭式外骨架结构形式衬套，各方向刚度比调整范围有限，无法达到最理想的刚度比。且实际生产中为消除高温硫化带来的应力，常需要增加一道缩径工艺，导致零部件生产流程长，成本高。通常的程序是：首先将内骨架与外骨架放在模具中，然后通过设备注入橡胶，在高温下进行硫化使内外骨架硫化在一起。调整X方向空心孔的大小，来调整 X/Y方向的刚度；一旦X方向空心孔的尺寸确定，X/Y方向的刚度也就确定，无法继续进行调整。急需设计一种生产工艺简单，调试范围广的后副车架衬套。
CN205047721U公开了一种副车架衬套，包括：多个子衬套块，所述子衬套块对接形成圆柱形主体，所述圆柱形主体由外到内由衬套外壳、橡胶层和衬套内芯组成，选取不同刚度的子衬套块对接形成圆柱形主体，以快速调整副车架衬套的各向刚度。由于子衬套块的刚度可以单独调试，并可以提前调试并测试好，将子衬套块做成标准子零件库。通过选取不同刚度的子衬套块对接形成圆柱形主体，可以快速调整副车架衬套的各向刚度。极大缩短了衬套刚度的调试时间，提高了工作效率，节省车辆开发前期副车架衬套的调试成本。毫无疑问，这是所属技术领域的一种有益的尝试。
发明内容
本发明的目的是提供一种后副车架衬套结构，解决现有后副车架衬套结构生产工艺复杂、调试范围有限的问题。
一种后副车架衬套结构，包括外骨架、橡胶套体和内骨架，各部件呈筒状且由外到内套接组成，其高度由外到内依次增高，所述外骨架为两半组成且中间有开口间隙，所述外骨架的高度高于橡胶的高度，所述橡胶套体由外套层和内套层组成，所述外套层和内套层之间的Y方向上设置有金属骨架，所述金属骨架呈片状，且外套层与内套层之间的X方向的空隙为X方向空心孔。
进一步地，所述金属骨架的横截面为中间呈弧形，两端平直。
进一步地，所述X方向空心孔的为弧形孔。
有益效果：本发明采用两部分组成且中间有开口间隙的外骨架，开口间隙可消除高温硫化带来的应力，从而省掉缩径工艺，且衬套装备后，开口间隙被压缩，预变形量较大，同时也提高了衬套的耐久性能。外套层与内套层之间设置金属骨架，外套层和内套层之间的金属骨架之外间隙为X方向空心孔，这样使X方向空心孔的可调范围增大，当
X方向空心孔的的大小根据X方向的刚度确定好以后，可通过改变金属骨架的弧度与厚度改变Y方向刚度，使其刚度调整范围大大增加。本发明可通过改变金属骨架来调整Y方向的刚度，使后副车架衬套的刚度调整范围增加，性能调试范围广；且本发明还具有耐久性能好、生产工序简单、优化成本等优点。

具体实施方式
下面结合附图对本发明进行进一步的描述:
如图3-6所示一种后副车架衬套结构，包括外骨架3、橡胶套体2和内骨架1，各部件呈筒状且由外到内套接组成，其高度由外到内依次增高，内骨架1材料可选用钢材、尼龙、铝合金等材料。所述外骨架3为两半组成且中间有开口间隙11，所述外骨架3的高度高于橡胶套体2的高度，所述橡胶套体2由外套层21和内套层22组成，所述外套层21和内套层22之间的Y方向上设置有金属骨架4，金属骨架4采用钢材，所述金属骨架4呈片状，且外套层21与内套层22之间的X方向的空隙为X方向空心孔5。
采用两部分组成且中间有开口间隙11的外骨架3，开口间隙11可消除高温硫化带来的应力，从而省掉缩径工艺，且衬套装备后，开口间隙11被压缩，预变形量较大，同时也提高了衬套的耐久性能。外套层21与内套层22之间设置金属骨架4，外套层21和内套层22 之间的金属骨架4之外间隙为X方向空心孔5，这样使X方向空心孔5的可调范围增大，X 方向空心孔5可减小该方向的动刚度，进一步减少振动，当X方向空心孔5的的大小根据X 方向的刚度确定好以后，可通过改变金属骨架4的厚度改变Y方向刚度，使其刚度调整范围大大增加。
装配时，将衬套沿着Y方向进行压缩。结合图5，衬套装配完成后，开口间隙11会被挤压合并，此时衬套在Y方向处于预压缩状态，预压缩量与衬套开口间隙11大小一致。在衬套X方向受力时，可通过衬套的预压缩量来吸收衬套的变形，改善衬套舒适性。
进一步地，所述金属骨架(4)的横截面为中间呈弧形，两端平直。可以同时改变金属骨架4的弧度和厚度来改变Y向刚度，金属骨架4的弧度和厚度与X/Y方向刚度比成负相关。若X向选用较小的刚度则可加大X方向空心孔5的尺寸，X方向空心孔5的尺寸确定后，可通过增大金属骨架4的弧度和厚度增大Y方向刚度。两端平直这样可使金属骨架4刚度更强。
进一步地，所述X方向空心孔(5)的为弧形孔。这样使其X方向空心孔5尺寸和刚度调整更加方便。
