Description

制动液压控制装置
技术领域
本发明涉及控制多个系统的液压回路的液压的制动液压控制装置。
背景技术
以往，已知借助液压回路控制被向制动部供给的制动液的液压来进行制动控制的制动液压控制装置。制动液压控制装置例如若为二轮车的话具备前轮用及后轮用的两个系统、若为四轮车的话具备前轮用及后轮用的两个系统或者使分别位于对角的前轮及后轮成组的两个系统的液压回路。
制动液压控制装置具备开闭自如的调整阀、与调整阀联动地动作的泵元件及驱动泵元件的电动马达等。制动液压控制装置被电子控制而自动地动作，使制动液压回路内的液压增减，由此控制车轮处产生的制动力。
例如，泵元件具有与设置于马达轴的偏心凸轮抵接而通过偏心凸轮的旋转来往复移动的活塞。泵元件随着活塞的往复移动经由吸入阀吸入制动液，经由排出阀排出制动液(例如参照专利文献1)。
专利文献1：日本特开2015-205686号公报。
这里，以往的制动液压控制装置中，相对于形成有液路的液压块，调整阀、泵元件及电动马达等所有零件被个别地组装。这些零件会分别成为音振（NVH）的发生嫄，所以需要采取相对于各个零件设置减振器等的音振对策。此外，若相对于液压块组装各个零件，则制动液压控制装置的外形变大，有相对于车辆的搭载性下降的可能。
发明内容
本发明是鉴于上述问题而作出的，提供能够使音振对策简易且能够使外形小型化的制动液压控制装置。
根据本发明的某观点，提供一种制动液压控制装置，其控制多个系统的液压回路的液压，具备压力供给单元和液压块，前述压力供给单元具备马达及泵元件，前述液压块具备与压力供给单元连接的液路及调节多个系统的液压回路的液压的控制阀，前述压力供给单元具备马达、斜板和泵元件，前述马达具有定子及转子，前述斜板被相对于转子的旋转轴的轴线方向倾斜配置，前述泵元件具有通过马达的旋转而被驱动的多个泵部，泵元件的至少一部分被配置于转子的内部。
发明效果
如以上说明，根据本发明，能够使制动液压控制装置的音振对策简易且使外形小型化。
附图说明
图1是表示本发明的实施方式的制动用液压回路的回路图。
图2是表示该实施方式的制动液压控制装置的示意图。
图3是表示该实施方式的压力供给模块的剖视图。
图4是表示该实施方式的泵元件的外观的立体图。
图5是表示该实施方式的泵元件的结构例的剖视图。
具体实施方式
以下，参照附图的同时对本发明的适合的实施方式进行详细的说明。另外，对于本说明书及附图中实质上具有相同的功能结构的结构要素，通过标注相同的附图标记来省略重复说明。
＜1.制动用液压回路＞
参照图1，对能够应用本实施方式的制动液压控制装置20的制动用液压回路1的结构例进行说明。
本实施方式的制动用液压回路1被应用于，不使用助力装置地将驾驶者对制动踏板10的踏力增幅来传递至轮缸的制动系统。图1中表示的制动系统是四轮车用的制动系统。但是，制动用液压回路1也可以被应用于，利用助力装置将驾驶者对制动踏板10的踏力增幅来传递至轮缸的制动系统。
制动踏板10在将车辆制动的情况被驾驶者进行踩踏操作。若为能够输入驾驶者的制动要求的要素，则也可以置换成制动踏板10的操作要素。
制动踏板10与活塞杆11连接。在活塞杆11处设置有用于检测该活塞杆11的轴向位移量即行程量的行程传感器8。
贮存罐16保持作为产生液压的流体的工作液。贮存罐16与主缸14连接，将工作液供给至主缸14内。
主缸14将第一活塞12a及第二活塞12b能够进退移动地保持。图1中表示的主缸14是串联式的主缸14，具有被第一活塞12a及第二活塞12b划分的两个压力室13a，13b。
第一活塞12a被设置于活塞杆11的末端。第二活塞12b经由配置于压力室13a的弹簧15a与第一活塞12a连接。在压力室13b配置有与第二活塞12b连接的弹簧15b。例如，两个弹簧15a，15b的弹簧力相同。
两个压力室13a，13b的各自的容量与活塞杆11的行程量对应地变化。两个压力室13a，13b分别与液压回路28，30连接。通过制动踏板10的操作，经由活塞杆11，第一活塞12a及第二活塞12b被推压，工作液移动至液压回路28，30。
制动液压控制装置20包括具有相同结构的两个液压回路28，30。工作液被从主缸14的一方的压力室13a供给至一方的液压回路28。工作液被从主缸14的另一方的压力室13b供给至另一方的液压回路30。
本实施方式的制动用液压回路1构成为，借助各个液压回路28，30将处于车辆的对角的位置的一个前轮及一个后轮成组地控制液压的所谓的X型配管方式。
图1所示的例子中，工作液被经由液压回路28供给至右前轮(FR)的液压制动器22a的轮缸38a及左后轮(RL)的液压制动器22b的轮缸38b。此外，工作液被经由液压回路30供给至左前轮(FL)的液压制动器22c的轮缸38c及右后轮(RR)的液压制动器22d的轮缸38d。
另外，制动系统不限于X型配管方式。此外，制动系统不限于四轮车用的制动系统，也可以是二轮车用或者除此以外的车辆的制动系统。
本实施方式的制动用液压回路1中，液压回路30具有与液压回路28相同的结构。以下，关于液压回路28进行说明，省略液压回路30的说明。
从主缸14的压力室13a供给工作液的液压回路28具备多个电磁阀。电磁阀包括常闭型且能够线性控制的回路控制阀36、常闭型且被开启关闭控制的吸入控制阀34、常开型且能够线性控制的增压阀58a，58b(以下，无需特别区别的情况下总称为增压阀58。)、常闭型且被开启关闭控制的减压阀54a，54b(以下，无需特别区别的情况下总称为减压阀54。)。
液压回路28具备被马达96驱动的泵部44。此外，液压回路28具备储蓄器71及减振器73。
回路控制阀36将主缸14和增压阀58a，58b之间连通或切断。吸入控制阀34将主缸14和泵部44的抽吸侧之间连通或切断。回路控制阀36及吸入控制阀34的驱动被图中未示出的电子控制单元(ECU:Electronic Control Unit)控制。
回路控制阀36具有具备止回阀40的旁路流路41。止回阀40能够经由从主缸14侧向右前轮的液压制动器22a及左后轮的液压制动器22b侧的旁路流路41使工作液移动。另一方面，止回阀40使工作液不能经由从右前轮的液压制动器22a及左后轮的液压制动器22b侧向主缸14侧的旁路流路41移动。
止回阀40例如在由于回路控制阀36的故障而回路控制阀36呈闭阀状态时，保障从主缸14侧向右前轮的液压制动器22a及左后轮的液压制动器22b侧的工作液的移动。

增压阀58a具有具备止回阀60a的旁路流路61a。止回阀60a使工作液能够经由从右前轮的液压制动器22a侧向主缸14及回路控制阀36侧的旁路流路61a移动。另一方面，止回阀60a使工作液不能经由从主缸14及回路控制阀36侧向右前轮的液压制动器22a侧的旁路流路61a移动。
止回阀60例如在由于增压阀58a的故障而增压阀58a呈闭阀状态时，保障工作液经由从右前轮的液压制动器22a侧向主缸14及回路控制阀36侧的旁路流路61a的移动。
减压阀54a是仅能够切换成全开及全闭的电磁阀。减压阀54被设置于右前轮的液压制动器22a的轮缸38a和储蓄器71之间。减压阀54a通过在开阀状态下将被供给至右前轮的液压制动器22a的轮缸38a的工作液供给至储蓄器71来减压。储蓄器71与经由减压阀54a，54b被供给的工作液的压力对应地使容积变化的同时将工作液蓄积或放出。
另外，减压阀54a通过断续地重复开闭，能够调节从右前轮的液压制动器22a的轮缸38a流至储蓄器71的工作液的流量。
增压阀58b被设置于将回路控制阀36和增压阀58a连接的管路与左后轮的液压制动器22b的轮缸38b之间。增压阀58b能够线性控制，将从主缸14、回路控制阀36、增压阀58a及右前轮的液压制动器22a的轮缸38a侧向左后轮的液压制动器22b的轮缸38b侧的工作液的流量连续地调整。
增压阀58b具有具备止回阀60b的旁路流路61b。止回阀60b使工作液能够经由从左后轮的液压制动器22b侧向主缸14及回路控制阀36侧的旁路流路61b移动。另一方面，止回阀60b使工作液不能经由从主缸14及回路控制阀36侧向左后轮的液压制动器22b侧的旁路流路61b移动。
止回阀60b例如在增压阀58b由于增压阀58b的故障而呈闭阀状态时，保障工作液经由从左后轮的液压制动器22b侧向主缸14及回路控制阀36侧的旁路流路61b的移动。
减压阀54b是仅能够切换成全开及全闭的电磁阀。减压阀54b被设置于左后轮的液压制动器22b的轮缸38b和储蓄器71之间。减压阀54b通过在开阀状态下将被供给至左后轮的液压制动器22b的轮缸38b的工作液向储蓄器71供给来减压。
另外，减压阀54b能够通过断续地重复开闭来调节从左后轮的液压制动器22b的轮缸38b流至储蓄器71的工作液的流量。
泵部44被马达96驱动而排出工作液。马达96的驱动被图中未示出的ECU控制。另外，泵部44的数量不限于一个。
泵部44的排出侧与将回路控制阀36和增压阀58a，58b连接的管路连接。在泵部44的排出侧设置有减振器73。减振器73具有减少伴随液压回路28内的工作液的流量的变化的振动或者振动音的功能。
在将回路控制阀36和增压阀58a，58b连接的管路与减振器73之间设置有可变节流阀31和止回阀32。可变节流阀31调整被经由减振器73供给来的工作液的流量。止回阀32能够使工作液从减振器73侧向将回路控制阀36和增压阀58a，58b连接的管路侧移动，另一方面，不能使工作液向其反方向移动。
在将减压阀54a，54b和泵部44的抽吸侧连接的管路处设置有止回阀69。止回阀69能够使工作液从减压阀54a，54b侧向泵部44的抽吸侧移动，另一方面，不能使工作液向其反方向移动。
在与主缸14的压力室13a连通的管路设置有第1压力传感器24。第1压力传感器24检测压力室13内的压力(主缸压)。在与右前轮的液压制动器22a的轮缸38a连通的管路设置有第2压力传感器26。第2压力传感器26检测轮缸压。另外，第2压力传感器26也可以设置于与左后轮的液压制动器22b的轮缸38b连通的管路。
另外，从主缸14的压力室13b供给工作液的另一方的液压回路30控制左前轮的液压制动器22c及右后轮的液压制动器22d。液压回路30除了将上述的液压回路28的说明中的右前轮的液压制动器22a的轮缸38a置换成左前轮的液压制动器22c的轮缸38c、将左后轮的液压制动器22b的轮缸38b置换成右后轮的液压制动器22d的轮缸38d以外，被与液压回路28相同地构成。
<2.制动液压控制装置的整体结构>
如图2所示，本实施方式的制动液压控制装置20具备压力供给单元90及液压块130。液压块130具备图中未示出的回路控制阀、吸入控制阀、增压阀、减压阀、压力传感器、储蓄器及减振器等，并且形成有具备将这些零件连接的多个液路的两个系统的液压回路。压力供给单元90具备马达96、具有两个泵部44的泵元件80，被安装于液压块130的一侧面130a。
马达96及两个泵部44分别以高速动作所以会成为音振的发生源。制动液压控制装置20构成为，使会作为音振的发生源的马达96及泵元件80一体化的压力供给单元90被安装于液压块130。例如圆环状的由弹性橡胶构成的减振器部件200位于压力供给单元90和液压块130之间，在压力供给单元90处产生的振动难以传递至液压块130。即，本实施方式的制动液压控制装置20中，借助一个减振器部件200实现马达96和两个泵部44的音振对策。
<3.压力供给模块>
参照图3至图5，对压力供给单元90的结构例具体地说明。图3是压力供给单元90的剖视图。图4是泵元件80的立体图，图5是泵元件80的剖视图。图5是图4中表示的泵元件80的I—I截面的剖视图，图3也是对应的位置的压力供给单元90的剖视图。
如图3所示，压力供给单元90被安装于液压块130的一侧面130a。压力供给单元90向液压块130的固定方法若为使在压力供给单元90处产生的振动衰减的方法则不被特别限定。例如，也可以在压力供给单元90的壳91处设置凸缘部分，使作为减振器的弹性橡胶位于其间，并且使螺栓贯通该凸缘部分来固定于液压块130。
压力供给单元90具备壳91、马达96及泵元件80。壳91具有圆柱形状的内部空间即容纳部91a，马达96及泵元件80被容纳于该容纳部91a。
马达96具备定子97及转子98。定子97被形成为圆环状，被沿壳91的容纳部91a的内周面安装。转子98被配置于定子97的内径侧，被绕轴能够旋转地轴支承。转子98具有向至少液压块130侧开口的凹部98a。以下，将旋转轴的延伸方向称作轴向。
在转子98的轴向的一端侧(图3的上侧)设置有轴部件101，该轴部件101被经由图中未示出的轴承支承于壳91的突设部92内。此外，转子98的轴向的另一端侧(图3的下侧)被经由轴承94支承于壳91。轴部件101延伸至转子98的凹部98a内，在凹部98a内的轴部件101的末端侧固定有旋转部件123。旋转部件123的朝向泵元件80侧的面形成为相对于轴向倾斜。旋转部件123与转子98一同轴旋转。旋转部件123也可以不固定于轴部件101而直接固定于转子98。
在旋转部件123的朝向泵元件80侧的面经由轴承125配置有斜板125。斜板125的与旋转部件123侧相反侧的面被泵元件80的两个活塞151支承。斜板125不随着转子98的轴旋转而旋转，但随着旋转部件123的轴旋转，配合相对于轴向倾斜的旋转部件123的面而倾斜方向变化。也可以构成为配合转子98的旋转而斜板125自身旋转，但本实施方式的制动液压控制装置20的结构例中，斜板125自身不旋转，所以能够减少由于斜板125和活塞151的摩擦引起的斜板125或者活塞151的磨损。
泵元件80经由形成于壳罩93的中央孔93a从液压块130侧插入设置于转子98的凹部98a内而被组装。泵元件80被固定于壳，不与转子98一同旋转。泵元件80的至少一部分被配置于凹部98a内即可，也可以是泵元件80全部被配置于凹部98a内。泵元件80具有绕轴以180度间隔配置的两个泵部44。
如图4及图5所示，泵元件80具有组装于泵体159的两个泵部44。两个泵部44具有同一结构。以下，对一个泵部44进行说明。
泵体159具备导入路169及排出路179作为工作液流动的液路。此外，泵体159具备工作液被经由导入路169导入的容纳室153，活塞151被沿轴向往复移动自如地配置于容纳室153。活塞151被活塞弹簧155向容纳室153的容积放大的方向施力。
在导入路169的途中设置有吸入阀161。吸入阀161具备阀体165、阀座部件163及阀弹簧167。阀座部件163具有工作液的通过孔163a，该通过孔163a借助阀体165开闭。阀体165被阀弹簧167向阀座部件163推压。吸入阀161构成为使工作液从液压块130侧向容纳室153侧通过单向阀。
在排出路179的途中设置有排出阀171。排出阀171具备阀体175、阀座部件173及阀弹簧177。阀座部件173具有工作液的通过孔173a，该通过孔173a借助阀体175开闭。阀体175被阀弹簧177向阀座部件173推压。排出阀171构成为使工作液从容纳室153侧向液压块130侧通过的单向阀。
导入路169及排出路179分别在与液压块130的一侧面130a相向的面具有开口部169a，179a。导入路169及排出路179分别与形成于液压块130的液路连通(参照图3。)。在该开口部169a，179a的周围形成有配置密封圈的槽部157a，157b。如图3所示，压力供给单元90被安装于液压块130的状态下，被泵元件80和液压块130夹持。由此，防止在导入路169及排出路179流动的工作液从液路漏出。规定密封圈202a、202b的位置的槽也可以被设置于液压块130侧。
<4.动作例>
对本实施方式的制动液压控制装置20的动作例进行说明。
ESP或者ABS的工作指令被输入电子控制单元时，电子控制单元驱动马达96。马达96被驱动时，转子98绕轴旋转。随之，斜板127的倾斜方向变化。因此，泵元件80具备的各个泵部44的活塞151在转子98旋转一周的期间在容纳室153内往复移动一次。
此时，随着斜板127的倾斜方向的变化，活塞151被活塞弹簧155施力而向末端侧移动，容纳室153的容积扩大。由此，容纳室153内的液压下降，排出阀171关闭，另一方面，吸入阀161打开，工作液被导入容纳室153。
进而，若斜板127的倾斜方向变化，活塞151被抵抗活塞弹簧155的作用力地推动，则容纳室153的容积变小。由此，容纳室153内的液压上升，吸入阀161关闭，另一方面，排出阀171打开，工作液被从容纳室153排出。
随着马达96的旋转，泵部44重复工作液的吸入及排出。活塞151的行程量与斜板125的倾斜角度对应地变化，所以通过调节斜板125的倾斜角度，能够设定来自泵部44的工作液的排出量。另外，两个泵部44被以180度间隔配置，所以工作液的吸入及排出为相反相位。
电子控制单元这样使工作液从泵部44排出且控制增压阀58及减压阀54等，控制在各个车轮38产生的制动液压。
<5.效果>
以上说明的本实施方式的制动液压控制装置20将会成为音振的发生源的马达96和泵元件80作为压力供给单元90一体化地安装于液压块130。因此，能够将相对于马达96和泵元件80的音振对策由共通的减振器部件200构成。
此外，制动液压控制装置20将泵元件80的至少一部分插入在马达96的转子98处形成的凹部98a内来构成。因此，将马达96及泵元件80单元化时，能够抑制轴向的尺寸变大，并且能够以未将泵元件80设置于液压块130的量使液压块130小型化。因此，能够使制动液压控制装置20的整体的外形小型化。
以上，参照附图的同时对本发明的优选的实施方式详细地进行了说明，但本发明不限于这样的例子。若为具有本发明所属的技术领域的通常知识的本领域技术人员，显然能够在记载于权利要求书的技术思想的范畴内想到各种改变例或修正例，可知它们也显然属于本发明的技术范围。
此外，上述实施方式中以搭载于四轮车的制动液压控制装置为例进行了说明，但本发明不限于该例，也可以是搭载于摩托车等二轮车等其他交通工具的制动液压控制装置。此外，上述实施方式中以具备两个系统的液压回路的制动液压控制装置为例进行了说明，但也可以是，制动液压回路具备三个系统以上的液压回路。
