Description

一种电动汽车双向滑行器
技术领域
本发明涉及到一种滑行器， 具体的说是一种电动汽车双向滑行器。
背景技术
电动汽车以车载电源为动力， 具有环保节能等特点， 但受车载电源容量 的限制， 其行驶速度和充电后的行驶里程均有一定的缺陷， 不得不频繁充电， 不仅加剧了车载可充电电源的使用寿命， 同时， 也给使用者的生活带来了不 便。
电动汽车在平路上正常行驶时， 往往只需要很少的电力提供即能在惯性 的作用下保持原速度行驶， 但在实际情况下， 一直保持在较大额度的电力提 供， 浪费了车载电源的电能； 而在电动汽车下坡时， 只需借助于自身重力和 惯性， 利用单向离合器即可实现滑行行走， 由于现有技术的单向离合器的滚 珠与外圈之间接触， 使得电动汽车在滑行时单向离合器的阻力增大， 缩短了 滑行距离。
现有技术中存在着单向传动的离合器， 传递动力时， 转轴、 滚珠以及外 壳接触， 从而传递动力； 当外壳转动、 转轴不转时， 需要手动操作使滚珠与 外壳脱离接触， 结构复杂， 需要及时操控才能实现滑行。
发明内容
为了解决现有单向离合器由于内部阻力导致的滑行距离短的问题或者人 工操控才能实现滑行的问题， 本发明提供了一种电动汽车双向滑行器。
本发明为解决上述技术问题采用的技术方案为： 一种电动汽车双向滑行 器， 包括转轴、 滑行转换器、 圆环形的滑行中控环和滑行器座， 滑行转换器 固定在转轴的一端， 转轴的另一端与电机的输出轴连接， 滑行器座与电动汽 车的后桥的驱动轴连接； 所述滑行中控环和滑行转换器均设置在滑行器座内， 滑行中控环环绕滑行转换器设置， 并且滑行中控环与滑行转换器以及滑行器 座的内壁均不接触； 在滑行中控环的圆周面上等间距设有定位窗孔， 定位窗 孔内设有圆柱形的锁柱， 锁柱的轴向与转轴的轴向平行；
所述滑行转换器为正八棱柱形， 滑行转换器的八个侧面与滑行器座的内 壁面相对， 所述滑行中控环上的定位窗孔设置为八个， 八个定位窗孔内设置 的锁柱分别对应于滑行转换器的八个侧面； 在锁柱的圆周面上设有环绕其一 周的限位凹槽， 滑行中控环的外圆周面上设有与限位凹槽对应的切槽； 一个 圆环形的回位簧设置在限位凹槽和切槽内， 并将锁柱压在滑行转换器的侧面 上； 所述滑行转换器的八个侧面均有两个对称设置的倾斜滚道面， 倾斜滚道 面顶部与滑行转换器的侧棱连接； 滑行转换器同一个侧面上的两个倾斜滚道 面底部通过定位浅槽过渡连接；
转轴旋转时， 锁柱由于惯性及离心作用沿一侧的倾斜滚道面逆着转轴旋 转方向运动， 并卡在倾斜滚道面与滑行器座内壁之间， 从而带动滑行器座旋 转， 驱动电动汽车运行； 转轴停止转动时， 锁柱被回位簧沿倾斜滚道面拉回 定位浅槽， 从而与滑行器座脱离， 实现电动汽车的滑行；
所述转轴与滑行转换器为一体结构；
所述滑行转换器相邻的两侧面之间通过弧面或平面过渡衔接；
所述滑行转换器上倾斜滚道面的倾斜角为 2-4° ；
所述滑行转换器上定位浅槽的曲率半径大于锁柱的曲率半径。
该双向滑行器的转轴与电机的输出轴连接， 滑行器座与电动汽车的后桥 连接。 由于滑行转换器为正八棱柱， 正八棱柱的八个侧面均有两个对称设置 的倾斜滚道面， 倾斜滚道面的顶部与滑行转换器的侧棱连接； 滑行转换器同 一个侧面上的两个倾斜滚道面底部通过定位浅槽过渡连接， 锁柱的初始位置 在定位浅槽内， 无论电机正转或反转， 锁柱由于离心力的作用被甩离原位， 卡在倾斜滚道面与滑行器座内壁之间并锁紧， 将电机的动力通过转轴、 滑行 器座传递给后桥；
下坡时， 电机停止， 锁柱在回位簧的弹性拉力作用下返回定位浅槽， 此 时， 锁柱与滑行器座的内壁之间不接触， 使得电动汽车在滑行时， 后桥带动 滑行器座空转， 不会将动力通过锁柱传递给电机； 同时由于两者不接触， 减 小了该双向滑行器的内部阻力， 从而使电动汽车的滑行距离更远。
该双向滑行器中， 锁柱为圆柱体， 保证了向两侧均可以滚动， 使得无论 电机正转或反转时均能锁紧， 进而使动力从转轴输出给滑行器座； 滑行中控 环的作用是保持锁柱的位移同步， 回位簧的作用不仅保证锁柱在电机不转时 处于滑行转换器侧壁上的定位浅槽内， 而且在电机停止转动时， 将锁柱从倾 斜滚道面与滑行器座内壁卡死的位置拉回原位， 脱离与滑行器座的接触， 切 断动力从滑行器座向转轴的传递路径。
有益效果： 本发明中， 该双向离合器通过正八棱柱的滑行转换器侧面上 的倾斜滚道面、 定位浅槽和圆柱形锁柱实现了不论电机正转或反转均能将动 力依次通过转轴、 滑行器座传递给后桥并驱动电动汽车运行， 转轴停止后通 过回位簧将锁柱自动拉回原位， 与滑行器座内壁脱离接触， 实现自动切换到 滑行模式， 同时， 减掉了该双向离合器内部的摩擦阻力， 使得电动汽车的滑 行距离更远， 延长了行驶里程。

具体实施方式
如图所示， 一种电动汽车双向滑行器， 包括转轴 1、 滑行转换器 101、 圆 环形的滑行中控环 3和滑行器座 4， 滑行转换器 101固定在转轴 1的一端， 且 两者为一体结构， 转轴 1 的另一端与电机的输出轴连接， 滑行器座 4与电动 汽车的后桥的驱动轴连接； 所述滑行中控环 3和滑行转换器 101均设置在滑 行器座 4内， 滑行中控环 3环绕滑行转换器 101设置， 并且滑行中控环 3与 滑行转换器 101 以及滑行器座 4的内壁均不接触； 在滑行中控环 3的圆周面 上等间距设有定位窗孔 301， 定位窗孔 301内设有圆柱形的锁柱 2， 锁柱 2的 轴向与转轴 1的轴向平行；
其中， 滑行转换器 101为正八棱柱形， 滑行转换器 101 的八个侧面与滑 行器座 4的内壁面相对， 滑行转换器 101相邻的两侧面之间通过弧面或平面 过渡衔接； 所述滑行中控环 3上的定位窗孔 301设置为八个， 八个定位窗孔 301内设置的锁柱 2分别对应于滑行转换器 101的八个侧面；在锁柱 2的圆周 面上设有环绕其一周的限位凹槽 201，滑行中控环 3的外圆周面上设有与限位 凹槽 201对应的切槽 302;—个圆环形的回位簧 5设置在限位凹槽 201和切槽 302内， 并将锁柱 2压在滑行转换器 101的侧面上； 所述滑行转换器 101的八 个侧面均有两个对称设置的倾斜滚道面 102， 倾斜滚道面 102的倾斜角为 2-4 ° ， 倾斜滚道面顶部 104与滑行转换器 101的侧棱连接； 滑行转换器 101同 一个侧面上的两个倾斜滚道面底部通过定位浅槽 103过渡连接，定位浅槽 103 的曲率半径大于锁柱 2的曲率半径；
转轴 1旋转时， 锁柱 2由于惯性及离心作用沿一侧的倾斜滚道面逆着转 轴旋转方向运动， 并卡在倾斜滚道面与滑行器座 4 内壁之间， 从而带动滑行 器座 4旋转， 驱动电动汽车运行； 转轴 1停止转动时， 锁柱 2被回位簧 5沿 倾斜滚道面拉回定位浅槽 103，从而与滑行器座 4脱离，实现电动汽车的滑行。
本发明中， 锁柱 2处于初始位置定位浅槽 103内时， 锁柱 2与滑行器座 4 内壁之间有间隙， 此时， 若电动汽车处于滑行状态时， 电机和转轴 1 均不转 动， 电动汽车的后桥带动滑行器座 4转动， 由于滑行器座 4与锁柱 2、 滑行转 换器 101均不接触， 因此， 不能将动力传输给转轴；
电动汽车正常行驶时， 电机带动转轴 1和滑行转换器 101转动， 锁柱 2 在惯性作用下被甩离原位并卡死在滑行转换器 101上的倾斜滚道面 102与滑 行器座 4内壁形成的间隙内， 此时， 滑行器座 4、 锁柱 2以及滑行转换器 101 依次接触构成动力传输线路， 将动力传输给滑行器座 4 以及与此连接的电动 汽车后桥， 进而驱动电动汽车行驶； 当切断电机后， 转轴 1及滑行转换器 101 停止转动， 锁柱 2在回位簧 5的作用下被拉回起始位置定位浅槽 103， 使得滑 行器座 4与锁柱 2和滑行转换器 101脱离接触， 防止电动汽车在滑行时后桥 将转动传递给转轴 1。
