如图 1 - 3所示， 一种汽车变速器换档减振减噪结构包括换挡杆手柄 10、 换挡拉索 20、 换挡执行机构总成 30、 多个叉轴 40、 多个换挡拔叉 50、 变速器壳体 60以及离合 器壳体 70， 换档杆手柄 10通过换挡拉索 20将换挡指令传递到换档执行机构总成 30， 换档执行机构总成 30通过换挡拔叉 50控制叉轴 40做轴向运动， 多个叉轴 40在轴向 移动过程中与变速器壳体 60或离合器壳体 70存在接触，叉轴 40的两端分别设有软橡 胶套 41。 由于在叉轴 40的两端分别设有软橡胶套 41， 使得叉轴 40做轴向运动时与变 速器壳体 60或离合器壳体 70发生软接触，避免了钢制的叉轴 40和铝合金材料的变速 器壳体 60或离合器壳体 70直接发生接触， 因而可完全消除换档操作时变速器引起噪 声， 对换档机构运动时也可以起到吸收振动能量和减轻振动的作用。
如图 4所示， 软橡胶套 41直接连接在叉轴 40上形成连接紧密的一体机。
如图 5和图 6所示， 叉轴 40轴向移动过程中， 软橡胶套 41会与变速器壳体 60 或离合器壳体 70发生摩擦， 鉴于软橡胶套 41 自身质量小， 容易在摩擦力的作用下与 叉轴 40发生分离。 因此， 软橡胶套 41 内部上设有一连接凹槽 45， 连接凹槽 45套接 在叉轴 40的两端上。 叉轴 40的一端部设有凸起连接部 42， 在连接凹槽 45的槽壁上 开设有一环形的固定槽 49， 凸起连接部 42卡接在固定槽 49中， 此结构可以确保叉轴
做轴向运动过程中， 软橡胶套牢固的固定在叉轴上， 不会因为摩擦力的作用使得软橡 胶套从叉轴上脱落。
在叉轴 40端部的外径上削出第一通风斜槽 43， 在凸起连接部 42的外径上削出第 二通风斜槽 44， 第一通风斜槽 43和第二通风斜槽 44在同一平面上。 上述两个通风斜 槽也是起到保证进出排气通畅、 减小叉轴运动时空气阻力的作用。
如图 7所示， 软橡胶套 41的底部还设有通风槽 47。 通风槽 47为三个， 三个通风 槽 47沿着软橡胶套 41的底部圆心向外延伸。 该通风槽 47也是为了确保当叉轴 40做 轴向运动过程中进出排气可以顺利通过， 叉轴 40不会遇到较大的空气阻力。
如图 8所示， 软橡胶套 41外部设有缓冲环槽 46。 该缓冲环槽 46在叉轴 40与变 速器壳体 60或离合器壳体 70之间发生接触时有效地起到缓冲作用。
此外， 软橡胶套 41 的外部自上至下形成一便于空气通行的拔模角度 48。 该拔模 角度 48使得软橡胶套 41上粗下细，可以确保当叉轴 40做轴向运动过程中进出排气可 以顺利通过， 叉轴不会遇到较大的空气阻力。
如图 9并参考图 3所示， 装有软橡胶套 41的叉轴 40在沿着轴向运动时会与变速 器壳体 60或离合器壳体 70发生接触， 软橡胶套 41可以确保上述部件之间的软连接， 避免钢制的叉轴 40和铝合金材料的变速器壳体 60或离合器壳体 70直接发生接触，因 此， 可以消除换档操作时变速器引起的噪声。
如图 10所示， 由于本汽车变速器换档减振减噪结构设有多个减小叉轴 40沿着轴 向运动产生的空气阻力部件： 通风槽 47、 拔模角度 48、 第一通风斜槽 43和第二通风 斜槽 44。 因而， 叉轴 40在沿着轴向运动时与变速器壳体 60或离合器壳体 70之间发 生接触时， 上述减小空气阻力的部件可以使得空气自由进出。
上面结合附图对本发明进行了示例性的描述， 显然， 本发明的实现并不受上述方 式的限制， 只要采用本发明的方法构思和技术方案进行的各种改进， 或未经改进将本 发明的构思和技术方案直接应用于其它场合的， 均在本发明的保护范围内。
