具体实施方式
以下,参照附图对本发明的优选的实施方式进行说明。
图1是表示涉及本实施方式的ABS液压单元的液压回路的回路图。涉及本实施方式的摩托车仅在前轮搭载有ABS(防抱死制动系统),ABS液压单元100设置为,能够仅对前轮执行防抱死制动控制。以下,对前轮的液压回路1进行说明。
液压回路1被制动液充满,以连接端A连接在主缸2上。主缸2安装有制动杆3,并且连接在蓄液器4上。由此,如果骑车者为了使前轮的制动器制动而操作制动杆3,则主缸2将储存在蓄液器4中的制动液向液压回路1排出。
另一方面,液压回路1以连接端B连接在轮缸5上。轮缸5设在前轮的制动钳6内,通过将轮缸5内的液压升压,使制动钳6动作,使前轮产生制动力。
连接在主缸2与轮缸5之间的液压回路1具备马达11、泵12、进口阀13、出口阀14及储液器15。
进口阀13是具备螺线管的电磁阀,以第1管21连接在连接端A上,另一方面,以第2管22连接在连接端B及出口阀14上。另外,第2管22通过在中途分支而与进口阀13、连接端B及出口阀14连接。进口阀13分别经由过滤器与第1管21及第2管22连接。进口阀13在两个过滤器之间并联连接着止回阀,该止回阀使得制动液不从第1管21向第2管22流动,但即使进口阀13关闭,也从第2管22向第1管21流过制动液。进口阀13通过开闭来控制从第1管21向第2管22的制动液的流动。
出口阀14是具备螺线管的电磁阀,以第2管22连接在进口阀13及连接端B上,另一方面,以第3管23连接在储液器15上。出口阀14经由过滤器连接在第2管22上。出口阀14通过开闭来控制从第2管22向第3管23的制动液的流动。
储液器15以第3管23连接在出口阀14上,另一方面,以第4管24连接在泵12的吸入侧。储液器15将从第3管23流入的制动液储存,此外能够使储存的制动液向第4管24流出。
泵12以第4管24连接在储液器15上,另一方面,以第5管25连接在第1管21上。泵12连接在第4管24上,经由节流部连接在第5管25上。泵12通过作为DC马达的马达11驱动而动作,从处于吸入侧的第4管24将制动液吸入,将吸入的制动液向处于排出侧的第5管25排出。
图2是表示由ECU执行的功能性方案的块图。
ECU40基于从检测前轮的旋转速度并输出对应的旋转速度信号的速度传感器41f、以及检测后轮的旋转速度并输出对应的旋转速度信号的速度传感器41r接收到的旋转速度信号,控制马达11的驱动、进口阀13及侧出口阀14的开闭状态等。
ECU40在通常的制动状态下,使马达11的驱动停止,将进口阀13保持为打开的状态,将出口阀14保持为关闭的状态。由此,如果骑车者操作制动杆3而由主缸2(参照图1)将制动液升压,则制动液的升压经过第1管21(参照图1)、进口阀13及第2管22(参照图1)被向轮缸5(参照图1)传递。因此,制动钳6(参照图1)以连动于由骑车者进行的制动杆3(参照图1)的操作的方式动作,使前轮产生制动力。
ECU40在由制动钳6产生制动力的制动时,基于从速度传感器41f、41r取得的旋转速度信号,反复判断前轮是否处于抱死状态、即前轮相对于路面是否过度地打滑在判断出前轮处于抱死状态的情况下,ECU40将进口阀13关闭,将出口阀14打开,使马达11驱动而使泵12动作,从而以将进口阀13及出口阀14开闭的方式进行控制,使得向轮缸5传递的制动液的液压下降。由此,ECU40对制动钳6的制动力进行防抱死制动控制,将前轮的抱死状态解除。
图3是表示ABS液压单元的立体图,图4是表示从ABS液压单元将壳体拆下的状态的立体图,图5是从ABS液压单元将壳体拆下的侧视图,图6是表示马达模组附近的剖视图。
ABS液压单元100如图3所示,将收纳ECU40(参照图2)的壳体42与块体50组合而构成。
块体50由铝形成。该块体50在内部具有液压回路1(参照图1),形成有作为供制动液流动的第1管21至第5管25的管路。块体50在与安装壳体42的壳体安装面51大致正交的配管连接面52上形成有连接端A及连接端B,并且装入有泵12及储液器15(参照图1)。
壳体42被安装在块体50的壳体安装面51上,将控制基板43、马达11、进口阀13及出口阀14(参照图4)覆盖。在壳体42被安装在块体50上的状态下、用来将控制基板43电气地连接到外部装置的连接器45向从块体50离开的方向突出地设置。该连接器45以被连接的连接器(未图示)覆盖连接器45的外周的方式组装。
壳体42一方面,覆盖马达11(参照图6)的部分42a和连接器45的用箭头z表示的z方向上的厚度大致相同地形成得较厚,另一方面,覆盖进口阀13及出口阀14的部分42b与覆盖马达11的部分42a相比,在朝向块体50的z方向上形成得较薄。
ABS液压单元100设置为,如果将壳体42拆下,则如图4所示,马达11、进口阀13、出口阀14及控制基板43露出。块体50的壳体安装面51在与壳体安装面51垂直的方向即z方向上形成有孔,在该孔中装入有马达11、进口阀13及出口阀14。进口阀13及出口阀14配置在马达11与控制基板43之间,马达11、进口阀13及出口阀14相对于块体50的壳体安装面51大致垂直地装入。
控制基板43搭载CPU及存储器等而构成ECU40,控制ABS液压单元100。该控制基板43具有当安装着壳体42时在连接器45(参照图3)内向外部露出的连接器部43a。控制基板43具有连接器部43a,由此与搭载有ABS液压单元100的摩托车的车体侧的连接器(未图示)连接,能够与车体侧互通车轮速度等各种各样的信息。
控制基板43如图5所示,配置为,马达11、进口阀13及出口阀14(参照图4)沿着向块体50装入的z方向延伸。即,控制基板43的面内方向与马达11、进口阀13及出口阀14向块体50装入的z方向大致平行。
控制基板43经由具有柔性的薄膜状的柔性配线44电气地连接到马达11、进口阀13及出口阀14。由此,控制基板43能够通过使进口阀13及出口阀14通电及非通电,来控制进口阀13及出口阀14的开闭,或能够控制马达11的旋转。
柔性配线44一端固定并电气地连接在控制基板43上,马达11、进口阀13及出口阀14分别通过连接端子11a、13a、14a插入到柔性配线44中并挂住而与柔性配线44电气地连接。
马达11如图6所示,经由沿着马达11的外周安装的马达安装部11b(固定部)被装入到形成在块体50的壳体安装面51上的孔51a中。在该孔51a中,在内部装入有行星齿轮机构30及偏心轴18。马达11的驱动力在被行星齿轮机构30减速后驱动偏心轴18。
行星齿轮机构30连结在马达11与偏心轴18之间,具备内齿轮31、行星托架32、恒星齿轮33及行星齿轮34。
内齿轮31形成有旋转阻止部,在孔51a内固定在块体50上且不旋转。内齿轮31形成有形成为环形状并沿着内周面排列的多个齿。
行星托架32形成为圆盘形状,配置在内齿轮31内。在行星托架32内,能够旋转地安装着3个行星齿轮34。行星齿轮34呈总是与沿着内齿轮31的内周面形成的齿啮合的状态。
行星托架32在3个行星齿轮34的中心配置有恒星齿轮33。恒星齿轮33呈在装入在行星托架32上的状态下总是与3个行星齿轮34啮合的状态。
行星托架32在轴心附近形成有孔,在贯通该孔延伸到行星托架32内的马达11的输出轴11c上组装着恒星齿轮33。恒星齿轮33以不能旋转的方式固定安装在输出轴11c上,恒星齿轮33和输出轴11c一体地旋转。
行星托架32在偏心轴18侧的轴心附近形成有孔,在该孔中组装固定着偏心轴18。由此,组装在该孔中的偏心轴18与行星托架32一体地旋转。
偏心轴18一端被行星齿轮机构30支承,与马达11同轴旋转的旋转轴部18a经由轴承19被块体50支承。偏心轴18的另一端绕作为相对于马达11的旋转轴偏心的轴的偏心部18b安装着球轴承20,从而将活塞运动向泵12平滑地传递。偏心轴18旋转而向泵12传递活塞运动,由此泵12使活塞往复移动,使制动液向液压回路1的第5管25(参照图1)排出。
行星齿轮机构30根据以上的结构,如果借助马达11的驱动力而组装在输出轴11c上的恒星齿轮33旋转,则与恒星齿轮33啮合的3个行星齿轮34分别向与恒星齿轮33相反的方向旋转。由于3个行星齿轮34分别还与内齿轮31啮合,所以3个行星齿轮34通过旋转而沿着内齿轮31的内周面移动。此时,3个行星齿轮34在内齿轮31内与恒星齿轮33旋转的方向同向地旋转移动。由于3个行星齿轮34装入在行星托架32上,所以行星托架32与3个行星齿轮34一体地在内齿轮31内旋转移动。由此,与行星托架32一体旋转的偏心轴18与恒星齿轮33同向地旋转。另外,涉及本实施方式的行星齿轮机构30为以下这样的减速比:马达11的输出轴11c的转速成为约1/5并从偏心轴18输出,另一方面,马达11的输出轴11c的转矩成为约5倍并从偏心轴18输出。即,例如当马达11以15000rpm(转/分)旋转时,输出轴11c以3000rpm旋转,当马达11以20000rpm旋转时,输出轴11c以4000rpm旋转。此外,在马达11的输出轴11c上是10N・cm的转矩在偏心轴18上成为50N・cm。
涉及本实施方式的马达11及行星齿轮机构30如图6所示,经由马达安装部11b被一体地固定,马达11、马达安装部11b及行星齿轮机构30作为马达模组10被一体地设置。马达安装部11b由铁等金属形成,从而防止磁力从马达11内逃出。
马达安装部11b形成为行星齿轮机构30侧的端部隆起而直径同轴地扩大的圆筒形状,在其一部分上形成有从行星齿轮机构30侧的端部连到马达11侧的端部的切口11d。该马达安装部11b形成为直径比马达11的外径稍小,设置为,如果以扩展的方式被挠曲而组装到马达11上,则将马达11夹在内侧地固定。
马达安装部11b设置为,将行星齿轮机构30的内齿轮31夹在内侧地固定。此时,也可以将马达安装部11b敛缝而更牢固地固定在内齿轮31上。马达安装部11b形成为,行星齿轮机构31侧的端部11e向从马达11的旋转轴的轴心离开的方向弯曲,而扩展为凸缘形状。
行星齿轮机构30的内齿轮31形成有凸缘部31a,该凸缘部31a向从马达11的旋转轴的轴心离开的方向扩展为凸缘形状,马达安装部11b的端部11e抵接在内齿轮31的凸缘部31a上。凸缘部31a的外径形成为与马达安装部11b的端部11e的外径大致相同。
在马达模组10中,马达安装部11b的行星齿轮机构30侧的端部11e及内齿轮31嵌合固定在形成于块体50上的孔51a的内表面上。此时,马达安装部11b的端部11e夹在内齿轮31与块体50之间,与内齿轮31及块体50密接地固定。
在本实施方式中,马达模组10具备马达11、安装在马达11的输出轴11c上的行星齿轮机构30、和将马达11及行星齿轮机构30一体地固定的马达安装部11b,马达安装部11b设置为,将马达11夹在内侧地固定,并将行星齿轮机构30的内齿轮31固定。由此,马达模组10仅通过将马达11及行星齿轮机构30插入到马达安装部11b内,就将马达11和行星齿轮机构30以同轴定位的状态一体地固定。由此,马达模组10不使用螺纹件,所以能够使零件件数变少,此外不需要将螺纹件拧入的工序,所以能够使组装所需要的工序变少。此外,由于马达11和行星齿轮机构30被高精度地同轴定位,所以能够使马达模组10驱动时的振动特性提高。
此外,在本实施方式中,在行星齿轮机构30的内齿轮31上形成有凸缘部31a。由此,当将行星齿轮机构30插入在马达安装部11b中时,马达安装部11b的端部11e碰抵在内齿轮31的凸缘部31a上。因此,马达模组10仅通过将行星齿轮机构30插入到马达安装部11b中,就能进行马达安装部11b和行星齿轮机构30在插入方向上的定位。
进而,在本实施方式中,马达安装部11b的端部11e扩展形成为凸缘形状,并且在行星齿轮机构30的内齿轮31上形成有凸缘部31a。由此,在马达模组10中,马达安装部11b的端部11e及内齿轮31的凸缘部31a能够嵌合固定到形成在块体50上的孔51a中。因此,在组装ABS液压单元100时,马达模组10仅通过插入到形成在块体50上的孔51a中就能够固定到块体50上。
以上,基于实施方式说明了本发明,但本发明并不限定于此。例如,在实施方式中,ABS液压单元100设置为能够仅对前轮执行ABS控制,但并不限定于此。例如,也可以通过连接到制动踏板的主缸及后轮的轮缸而设置为能够仅对后轮执行ABS控制。
此外,在上述实施方式中,使用圆筒形状的马达安装部11b,但并不限定于此。马达安装部只要能够将马达夹在内侧地固定,也可以具有其他的形状。
进而,在上述实施方式中,马达安装部11b将内齿轮31夹在内侧地固定,但并不限定于此。马达安装部只要能够将内齿轮固定,也可以借助其他的固定方法将内齿轮固定。
进而,此外,在上述实施方式中,在马达模组10中,马达安装部11b的端部11e及内齿轮31的凸缘部31a嵌合固定在形成于块体50上的孔51a中,但并不限定于此。只要能够将马达模组固定到块体上,也可以是马达安装部及内齿轮的某一个嵌合在形成于块体上的孔中。
