如图1和图2所示，上支架1和下支架2均采用U型件，通过开口相对的扣设或套设的方式连接，可以减少二者的装配垂直空间，并且U型件节省材料和成本，扣设或套设的方式不限于上支架1的两个侧板之间的开口宽度大于下支架2的两个侧板的宽度，将下支架2的两个侧板均套设在上支架1的两个侧板的内侧，或者反之也成立，或者二者的两个侧板分别内外交替套设，都可以，优选地方式中需要设置上支架1的两个侧板的沿顶板垂直方向的高度等于下支架2的沿底板的垂直方向的高度，保证套设后的上支架1和下支架2的侧板的端面能够分别止抵于顶板或侧板上，增加垂直方向或竖直方向上的承载力。

在一些实施例中，所采用的减震软垫42包括但不限于橡胶软垫或橡胶气囊垫，厚度远大于普通的橡胶垫片，起到很好的隔震减震效果，并且两个减震软垫42分别设置在上支架1的上下两侧，可以减缓下方减速器或减速箱的震动传导或车架横梁100，也能够减缓上方车架横梁100的震动传导给减速器或减速箱，起到双向减震效果。

基于上支架1和下支架2均采用U型件的结构，本实施例中在二者连接处设置套筒6，可以在横向支撑两侧的侧板，便于安装和紧固，防止变形。

本实施例的变速器辅助悬置装置，通过设置可拆卸式连接的上支架1和下支架2，在上支架1和下支架2的侧板之间设置套筒6，且套筒6的两端能够止抵于侧板上，可以增加上支架1和下支架2之间的连接稳定性，减少装配空间，并且安装简单，防止上支架1和下支架2的连接过程中发生变形，有利于增加二者的连接强度和预紧力。在上支架1的上下两侧设置减震软垫42可以进一步提高车架横梁100与变速器之间的减震效果；相比于现有技术中常规的减震垫圈，减震软垫42能够更好的吸收震动能力，提高双向减震效果。

如图3，减震组件4还包括垫板43和限位垫圈44，垫板43套设在第一螺栓件上3，限位垫圈44设于垫板43的内孔且能够夹设于内孔与第一螺栓件3的外周壁之间以将减震软垫42预安装于上支架1和第一螺栓件3上。由图3可见，垫板43从第一螺栓件3的顶部套设，垫板43的一个侧面能够与上支架1上方的减震软垫42的上端面接触，限位垫圈44采用塑料材质，设于垫板43的内孔和第一螺栓件3的外周壁之间，由于塑料材质的限位垫圈44的弹性作用，能够将减震软垫42和上支架1预紧连接在第一螺栓件3上，需要安装时，直接将第一螺栓件3的端部再次穿设车架横梁100，并通过第一螺母件31螺纹锁紧即可，安装方便快速。需要说明的是，垫板43的内孔径大于所述第一螺栓件3的外径，但是小于第一螺栓件3上套设的套管的外径。另外在安装时，第一螺母件31与车架横梁100之间设置至少一个垫片45，第一螺栓件3的头部与减震软垫42之间设置至少一个垫片45，起到调节高度和便于安装的作用。

如图4，上支架1上设置的第一通孔11为长圆孔，第一通孔11的长轴方向垂直于车架横梁100的长轴方向。便于调整上支架1在车架横梁100上安装位置，提高安装效率。

如图4和图5，上支架1的侧板上设有第三通孔12，下支架2的侧板上设有第四通孔22，第三通孔12或第四通孔22为长圆孔，第三通孔12或第四通孔22的长轴方向为竖直方向。本实施例中是设置第三通孔12为长圆孔，第四通孔22为圆孔，二者设置形状可以互换。此时，第三通孔12的长轴方向为竖直方向，即沿车架横梁100和变速器的安装方向，便于调整变速箱或变速器的安装距离，以适应不同种类和不同车架宽度的情况，提高通用性。

可选地，车架横梁100上设有第五通孔，第一螺栓件3依次穿设在第一通孔11和第五通孔内并通过第一螺母件31锁紧，第五通孔为长圆孔，第五通孔的长轴方向沿车架横梁100的长轴方向，如图1所述双箭头的方向，相当于整车的前后方向，用以调节变速器在前后方向的位置，增加该变速器辅助悬置装置的通用性。第五通孔配合第三通孔12和第一通孔11，三者实现对于变速器相对于整车在前后方向、高度方向和宽度方向的调整，通过三轴位置的调整，变速器辅助悬置装置可以满足不同品种变速器、不同车架宽度、动力总成与车架相对高度的通用性，减少零件种类。

如图2和图7，下支架2的两个侧板套设在上支架1的两个侧板的外侧且贴靠，第三螺栓件7依次穿设四个侧板以连接上支架1和下支架2，套筒6套设在第三螺栓件7上，且套筒6的两端分别止抵在上支架1的两个侧板上。

由于本实施例中上支架1和下支架2均为U型件，因此在二者套设连接后中间形成空腔，在空腔内设置套筒7且使得套筒7的两端能够止抵在上支架1的两个侧板的内侧，上支架1的侧板的外侧与下支架2的侧板的内侧相贴靠，第三螺栓件7锁紧的时候，套筒4能够支撑并防止侧板在第三螺栓件7上的轴向变形，增加预紧力。并提高安装稳定性。同理，当上支架1的侧板套设在下支架2的侧板外侧时，则套筒7两端止抵在下支架2的两侧板的内侧。

可选地，第三螺栓件7为外六角螺栓或外方形头部螺栓，便于连接安装。

如图5和图6，下支架2的一个侧板设有向外再向上的翻边23，翻边23与侧板平行，翻边23上设有第六通孔231，第六通孔231的内孔与第三螺栓件7的头部形状相配合，或者第二螺母件71的外部形状相配合，第二螺母件71螺纹连接于第三螺栓件7上。第三螺栓7从四个侧板的一侧穿设到另一侧，并通过第二螺母件71紧固，在紧固时，翻边23上的第六通孔231可以起到扳手的作用，对第一螺母件71和第三螺栓件7之间的相互转动进行转动限位，便于紧固安装和拆卸。可以理解，翻边23的立板与所在侧板之间的距离小于第三螺栓7的头部厚度或小于第二螺母件71的厚度，便于安装时将头部或第二螺母件71的外圆周卡接限位于第六通孔231内；第六通孔231与第四通孔22同轴设置。

可选地，第一通孔11、第二通孔21、第三通孔12和第四通孔22分别设有至少两个，且分别沿车架横梁100的长轴方向间隔设置。如图1所示，整个变速器辅助悬置装置在安装时沿车架横梁100的长轴方向的长度较大，因此间隔设置至少两个连接固定点，利于安装稳定性。当然根据需要，可以在垂直于长轴方向增设连接固定点，或者沿长轴方向增设连接固定点，这里不一一列举。

如图4，上支架1的顶板上和车架横梁100上均设有安装孔13，安装孔13与第二通孔21的位置相对应且同轴设置。可以理解，安装孔13的孔径要尽量的大一些，便于安装第二螺栓件5以连接变速器或变速箱。

上述实施例中涉及到螺栓与螺母配合的结构中，螺栓上均可以选择配合垫片45实现安装。

应用本实施例提供的变速器辅助悬置装置，在将变速器或变速箱安装在车架横梁100上时，通过如下过程实现：

首先，在第一螺栓件3上依次套设垫片45、套管41、减震软垫42、上支架1、另一个减震软垫42、垫板43和限位垫圈44以形成预紧组件。

第一螺栓件3再次穿设车架横梁100上的第五通孔并通过第一螺母件31松配合连接。

将下支架2连接于上支架1上并在第三通孔12和第四通孔22之间松连接。

第二螺栓件5从上到下依次穿过车架横梁100上的安装孔13、上支架1的顶板上的安装孔13以及下支架2的底板上的第二通孔21，螺纹连接于变速器或变速箱。

根据两个松连接的装配空间，调整变速器或变速箱的三轴位置，最后连接固定变速器或变速箱。

显然，本实用新型的上述实施例仅仅是为了清楚说明本实用新型所作的举例，而并非是对本实用新型的实施方式的限定。对于所属领域的普通技术人员来说，能够进行各种明显的变化、重新调整和替代而不会脱离本实用新型的保护范围。这里无需也无法对所有的实施方式予以穷举。凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型权利要求的保护范围之内。
