The utility model solves the problem of improving the jitter phenomenon of shifting handball and meeting the lightweight design requirements. The technical scheme of the utility model is that the cross section of the bracket is L-shaped, the edge of the bracket is provided with a limited bend, the position between the bend edge of the clamp fixing hole and the bracket is provided with a shift side reinforcement bar and a shift side reinforcement bar, the bottom surface of the bracket is provided with a number of through holes and shock absorption components, and the rectangular groove of the shift pull line card and the rectangular groove of the shift pull line card are respectively arranged. In the circular groove of the shift pulling wire and the circular groove of the selector pulling wire of the support, an intermediate reinforcing bar is arranged between the circular groove of the shift pulling wire and the circular groove of the selector pulling wire. The utility model has the advantages that, on the basis of realizing the original function, the rubber washer and the metal washer are introduced, the aluminum alloy die-casting manufacturing process is adopted, the structure design of the wire-drawing support is more flexible, and the interior space of the vehicle can be fully utilized.
【技术实现步骤摘要】
一种新型换档拉线支架
本技术属于变速器
,特别涉及一种新型换档拉线支架。
技术介绍
选换档拉线支架是手动变速器换档系统中重要的组成机构,其主要作用约束选换档拉线,从而使选换档拉线可靠地约束在整车的精确位置,保证选、换档拉线的设计走向,避免换档过程中选档拉线和换档拉线的干涉,使选换档拉线能够稳定顺畅的推拉选档摇臂和换档摇臂,完成换档过程。汽车在在行驶过程中,驾驶室内的换档手球常常会出现抖动的现象,这不但会加快换档机构零件的磨损,而且会直接影响驾驶员在换档过程中的驾驶感受。目前手动变速器选换档拉线支架结构中,大多采用钢板冲压焊接工艺制造选换档拉线支架,质量大且无减振功能,固定方式采用两点螺栓固定。这种结构的选换档拉线支架会导致动力总成的振动通过拉线支架传递给选、换档拉线,进而由选、换档拉线传递到驾驶室内的换档手球,导致手球抖动,直接加快运动部件的磨损和影响驾驶感受。本技术所要解决的问题是改善换档手球抖动现象和满足轻量化设计要求。
技术实现思路
本技术的目的是提供一种新型换档拉线支架。本技术的目的是这样实现的,支架的截面为L形,支架的边缘处设置有限位弯边,限位弯边上设置有卡子固定孔弯边与支架间的位置上设置有换档侧加强筋和选档侧加强筋,支架的底面上设置有若干通孔和减震组件;换档拉线卡片矩形槽与选档拉线卡片矩形槽分别设置在支架的换档拉线圆形槽和选档拉线圆形槽内,换档拉线圆形槽和选档拉线圆形槽之间设置有中间加强筋。所述减震组件由金属衬套和橡胶垫圈组成。本技术的优点是:本技术在实现原功能的基础上,引入了橡胶垫圈和金属垫圈,采用铝合金压铸制造工艺,拉线支架结构设计更为灵 ...
