本发明的实施方式
根据上述一种车用大扭矩无级变速器在使用时,驾驶员打开点火锁、电源开关开启,此时、电源开关给全车电路供电、同时给多路控制器、一号电子调压器、二号电子调压器供电,驾驶员发动引擎、发动机转速感应器将发动机的转速信号实时传递给多路控制器进行计算、车速感应器感应到车速计数盘的转速为零同时将信号传递给多路控制器进行计算、多路控制器控制一号电子调压器将电压调至最高供给起步线圈、起步线圈开始工作起步磁钢产生磁力将阻力磁钢吸住使其难以转动、阻力磁钢再通过二级阻力装置(阻力磁钢通过二级阻力齿圈对二级阻力被动行星齿轮进行制动、二级阻力被动行星齿轮对二级阻力行星齿轮中轴进行制动、二级阻力行星齿轮中轴对二级阻力从动行星齿轮进行制动、二级阻力从动行星齿轮对二级主动齿圈进行制动,上述结构反向运动即为增速装置)和一级阻力装置(一级阻力齿圈对阻力被动行星齿轮进行制动、阻力被动行星齿轮对阻力行星齿轮中轴进行制动、阻力行星齿轮中轴对阻力从动行星齿轮进行制动、阻力从动行星齿轮对一级主动齿圈进行制动,上述结构反向运动即为增速装置)阻止行星齿轮支架旋转,当驾驶员通过档杆及连杆推动拨杈拨动换向轮向左滑动迫使换向轮左边的同步器与前进档从动齿轮右边的同步轮啮合,驾驶员轻踩加速踏板、发动机开始加速、发动机的飞轮轴带动液力变矩器开始旋转、液力变矩器带动输入轴开始顺时针旋转,输入轴带动输入轴主动齿轮同步旋转同时拨动从动行星齿轮逆时针旋转、从动行星齿轮通过行星齿轮中轴带动被动行星齿轮拨动中间轴从动齿轮顺时针旋转,中间轴从动齿轮通过中间轴带动调速磁钢、前进档主动齿轮、倒档主动齿轮、滑环同步旋转,前进档主动齿轮拨动前进档从动齿轮带动换向轮以及输出轴逆时针旋转,输出轴带动车速计数盘、传动轴、主减速器、差速器、半轴驱动车轮旋转后推动汽车前进,当车速感应器向多路控制器传递的行车速度信号大于5-10km/h时,多路控制器控制一号电子调压器将电压快速降低直至归零、多路控制器同时控制二号电子调压器将电压快速调至最高电压的1/10并且供给调速线圈开始工作、调速磁钢产生磁力后通过磁力吸引着阻力磁钢开始不同步的旋转,此时、多路控制器同时计算发动机的转速以及车速计数盘的转速、依快速增加车速计数盘转速的方式不间断地调控二号电子调压器输出的电压,在此同时、输入轴主动齿轮拨动从动行星齿轮和被动行星齿轮逆时针自转的同时、由于中间轴从动齿轮受到驱动汽车前进的阻力会对被动行星齿轮产生相反的阻力、迫使被动行星齿轮通过行星齿轮中轴推动行星齿轮支架依小于输入轴的转速顺时针旋转使被动行星齿轮和从动行星齿轮在自转的同时围绕着输入轴主动齿轮以及中间轴从动齿轮低速公转将输入轴大于中间轴的部分转速消耗掉、行星齿轮支架通过带动一级阻力装置及二级阻力装置旋转的同时对二级阻力齿圈进行增速、此时的调速磁钢与阻力磁钢之间的转速比达到最大值,多路控制器计算发动机的转速以及车速计数盘的转速后控制二号电子调压器输出的电压逐步增大、迫使调速磁钢与阻力磁钢之间的转速比逐步缩小、同时利用阻力磁钢通过二级阻力装置和一级阻力装置对行星齿轮支架进行降速、减小被动行星齿轮和从动行星齿轮围绕着输入轴主动齿轮以及中间轴从动齿轮公转的转速损失、同时增大了中间轴的转速,最终多路控制器控制二号电子调压器输出最大电压、迫使调速磁钢将阻力磁钢吸住使其转速同步后既输入轴与中间轴转速同步,若汽车需要减速时、多路控制器接收到发动机的转速下降后会控制二号电子调压器将电压逐步降低、由于中间轴受到推动汽车前进的阻力以及调速磁钢的磁力减小、迫使调速磁钢与阻力磁钢之间的转速比会逐步增大、二级阻力装置和一级阻力装置以及行星齿轮支架会根据调速磁钢的磁力大小调配中间轴转速的同时按照上述反向工作、直至车速小于5-10km/h后起步磁钢再次将阻力磁钢吸住,既调速磁钢与阻力磁钢之间的转速比越大车速就会越慢、调速磁钢与阻力磁钢之间的转速比越小车速就会越快,至此上述加速及降速实现了无级变速的目的,驾驶员需要倒车时、通过档杆及连杆拉动拨杈拨动换向轮向右滑动迫使换向轮右边的同步器与倒档从动齿轮左边的同步轮啮合、在此同时倒档开关向多路控制器发出倒车指示、在倒车过程中多路控制器控制一号电子调压器将最高电压供给起步线圈、整个倒车过程阻力磁钢为静止状态、输入轴与中间轴之间保持最大转速比,当中间轴带动倒档主动齿轮通过倒向齿轮拨动倒档从动齿轮旋转后、倒档从动齿轮通过输出轴、传动轴、主减速器、半轴将动力传递给车轮使其反向旋转拉动汽车向后倒退。
