附图用来提供对本发明的进一步理解, 并且构成说明书的一部分, 与本 发明实施例一起用于解释本发明, 并不构成对本发明的限制。 在附图中: 图 1为本发明第一实施例的等角视图。
图 2为本发明第一实施例的***视图。
图 3为本发明的增益量表, 该表揭示有关在不同车速的情况下方向盘位 置与指定的接头角度的关系。
图 4为本发明的数据图表, 该表揭示在不同车速的情况下最大容许转速 与马达辅助接头的相互关系。 具体实施方式
本发明的目的在于提供一种更高敏感度的铰接接头***, 该系同能够对 接头角度进行更高敏感度的控制, 进而加强铰接巴士的驾驶性能与驾驶*** 的完整性; 一般而言, 铰接巴士通常是由一前车框架与一拖车框架所组成, 其中,该前车框架与拖车框架包含一组转向前轮、一组中间车轮与一组后轮, 并由连接至后轮的驱动轴来推动铰接巴士。
现请参阅图 1与图 2 , 其为本发明的第一实施例。 图 1与图 2揭示了在铰接 巴士中建构本发明所需要的基本构件, 其中包含一上部定子构件 106 与一 下部定子构件 103 设置于前车框架 101 ; —扁平转子 105 设置于该上部定 子构件与下部定子构件之间, 其具有两个转子延伸部件经由一水平轴 116 连接至一悬臂构件 104 以容许前车框架 101 与拖车框架 102 之间的上下 位移; 一上轴承 109 安装于上轴承槽 115 介于扁平转子 105 与上部定子 构件 106 之间, 一下轴承 108 安装于下轴承槽 114介于扁平转子 105 与 下部定子构件 103 之间, 以容许前车框架 101 与拖车框架 102 之间的旋 转动作。 马达辅助接头***还包含一控制单元, 用以读取方向盘位置、 接头位置 以及车速等相关信息。
现请参阅图 3 , 如该图所揭示的一控制方法, 控制单元依据车速对目标 接头角度进行计算上不同的增量设定, 其中, 当铰接巴士在以高速向前直线 行驶时, 目标接头角度相较于低速行驶时会较小;例如当铰接巴士以每小时 40英里进行换线动作时, 驾驶若将方向盘转动 10度, 则控制单元会设定目标 接头角度为 5度角以获得较高的稳定性; 又如果铰接巴士是以每小时 5英里的 速度进行换线时, 当驾驶将方向盘转动 10度, 则控制单元会将目标接头角度 设定为 8度角以获得较顺畅的转向动作; 因此, 控制单元必须依据检测到的 车速才能对目标接头进行角度上的调整。
如图 3所揭示, 当车速增加至超过一低速标准值时, 对应方向盘位置的 目标接头角度值的增量相对而言增加的较多, 这是因为需要较大的接头角度 才能进行转向的动作, 而当车速增加至超过另一个高速的标准值时, 对应方 向盘位置的目标接头角度值的增量则又相对的减少, 以在换线时获得较好的 稳定性。
又如图 3所揭示, 对应方向盘位置的目标接头角度值在车辆进行倒车时 亦会有相较较多的增加, 这是因为铰接巴士的传动轴多设置于拖车车轴, 因 此, 倒车时会因为车轴的位置而产生一反向的拉扯力道将铰接接头拉扯至一 垂直的位置, 为了使铰接巴士能够行驶于一较顺畅的倒车轨道上, 便需要在 进行倒车动作时给鱼该数值更高的增量; 因此, 控制单元便需要在进行倒车 动作时增加目标接头角度的数值。
现请参阅图 4, 如该图所揭示, 是第一实施例的另一控制方法, 其中, 接头的最大角速度是依据车速所决定; 在图 4中接近零的区块附近, 铰接巴 士是以极低的速度行驶, 以适当的控制马达辅助接头并避免车轮的磨损, 若 铰接巴士的车速未超过预设的标准值, 则液压转台的角度将不被允许进行任 何改变, 因此, 设置一车速标准值来判定是否容许马达辅助接头的转动是必 须的。
又如图 4所揭示, 可以看到, 在车速达到另一预设的高速标准值时, 控 制单元又一次的限制了马达辅助接头的最大角速度, 这是因为这时候液压转 台转动的速度会影响车辆行驶的稳定性与舒适度, 这种情况通常发生在铰接 巴士行驶于高速公路上时, 故而马达辅助接头的最大角速度需要直接具车速 来调整判定。
在某些应用上, 如图 1与第二途的磁铁与线圈的功效是可互相取代的, 如设置于转子上的磁铁或设置于定子上的线圈。 发明的精神和范围。 这样, 倘若本发明的这些修改和变型属于本发明权利要 求及其等同技术的范围之内, 则本发明也意图包含这些改动和变型在内。
