Description

液压制动系统
技术领域
本发明涉及一种液压制动系统，更详细地，涉及可以降低从泵排出的制动液的压力脉动的液压制动系统。
背景技术
通常，液压制动系统包括：多个电磁阀，设置在调制模块中，用于控制向车辆的制动器传递的制动液压；低压储油器和高压储油器，用于临时储存油；泵，设置在低压储油器与高压储油器之间，用于泵送储存在低压储油器中的油；以及马达，用于驱动泵，还包括用于控制对上述构件进行电操作的结构组件的电子控制装置(ECU)。
上述的液压制动系统中设置有具有规定的阻尼空间的高压储油器，以用来降低从泵排出的制动液形成为高压而产生的压力脉动，并采用在通过高压储油器排出的输出端口上设置节流孔的结构。此时，为了使压力脉动的降低效果达到最大，将流入到高压储油器的输入端口和从高压储油器排出的输出端口尽量形成在相互隔开的距离最大的位置上。在专利公报第10-2003-0006155中公开了具有上述的高压储油器的液压制动系统。
然而，为了控制制动液压，形成在调制模块的多个流路需要将设置在调制模块内的多个电磁阀与泵、低压储油器及高压储油器等进行连接，这会导致流路的结构变得复杂，因此，将与高压储油器连接的输入端口和输出端口任意隔开设置时，在流路设计和工艺方面存在困难，而且制造成本也会上升。
并且，在同一线上设置与高压储油器连接的输入端口和输出端口，具有便于制造的优点，但是因输入端口和输出端口靠近而导致降低压力脉动的性能会下降。

具体实施方式
下面，参照附图对本发明的实施例进行详细说明。下面的实施例是为了向本技术领域的技术人员充分转达本发明的思想而提出的。本发明并不限定于下面的实施例，还可以以其他方式实施。为了清楚地说明本发明，在附图中省略了与说明无关的部分，为了便于理解，将组成部分适当放大表示。
图1是概略地表示本发明的一个优选实施例的液压制动系统的液压回路图。
参照图1，液压制动系统包括：制动踏板10，接收驾驶员的操作力；制动助力器11，通过所述制动踏板10的踏板力并利用真空压和大气压之间的压差，使踏板力倍增；主缸20，通过所述制动助力器11产生压力；第一液压回路40A，连接所述主缸20的第一端口21与设置在两个车轮FR、RL的轮缸30，由此控制液压的传递；第二液压回路40B，连接主缸20的第二端口22与设置在其余的两个车轮FL、RR的轮缸30，由此控制液压的传递。第一液压回路40A和第二液压回路40B紧凑地设置在调制模块上。
第一液压回路40A和第二液压回路40B分别包括：各两个电磁阀41、42，其用于控制向轮缸30传递的制动液压；泵44，通过马达45的驱动抽吸从轮缸30流出的制动液或者从主缸20流出的制动液，并进行泵送；低压储油器43，用于临时储存从轮缸30流出的制动液；主流路47a，连接泵44的排出口与主缸20；辅助流路48a，向泵44的入口引导主缸20的制动液，使其被抽吸；以及电子控制单元(EUC，未图示)，其用于控制多个电磁阀41、42以及马达45的驱动。
此时，如图所示，在第一液压回路40A和第二液压回路40B中分别设置有电磁阀41、42、低压储油器43、泵44、主流路47a以及辅助流路48a。
更具体地，多个电磁阀41、42与轮缸30的上游侧和下游侧连接，所述电磁阀41、42区分为：常开型电磁阀41，配置在各轮缸30的上游侧，且平常保持开启的状态；常闭型电磁阀42，配置在各轮缸30的下游侧，且平常保持关闭的状态。所述电磁阀41、42的开闭操作可通过电子控制单元(未示出)进行控制，通过减压制动开启常闭型电磁阀42，从轮缸30流出的制动液临时储存在低压储油器43中。
泵44通过马达45来驱动，抽吸储存于低压储油器43的制动液并排出，从而将液压传递至轮缸30侧或者主缸20侧。
并且，在连接主缸20与泵44的排出口的主流路47a上设置用于牵引力控制系统(TCS)的常开型电磁阀47(以下，称为TC阀)。该TC阀47平常保持开启的状态，由此当通过制动踏板10来进行一般的制动时，从主缸20形成的制动液压通过主流路47a被传递至轮缸30侧。
并且，辅助流路48a从主流路47a分出，其向泵44的入口侧引导主缸20的制动液，使其被抽吸，在辅助流路上设置有换向阀48，以使制动液只能向泵44的入口流动。电性运行的换向阀48设置在辅助流路48a的中间位置，平常处于关闭状态，而在TCS模式下开启运行。
另一方面，未进行说明的附图标记“49”表示设置在流路的适当位置的止回阀，其防止制动液的反向流动，附图标记“50”表示压力传感器，其检测传递至TC阀47和换向阀48的制动压力，附图标记“51”表示节流孔。
如上所述的液压制动系统在进行制动期间，通过马达的驱动从泵44泵送的液压产生压力脉动，因此，根据本发明的一个实施例，为了降低压力脉动，提供与各液压回路40A、40B的泵44的排出端连接的高压储油器100。
图2是表示设置在本发明的一个优选实施例的液压制动系统的高压储油器组装在调制模块的状态的分解立体图，图3是图2的组装立体图，图4是表示通过设置在所述液压制动系统中的高压储油器，压力脉动降低的制动液的流动的剖视图。
参照图2至图4，本发明的一个实施例的高压储油器100设置在与从泵(参照图1的“44”)排出的制动液流入的输入端口102和排出制动液的输出端口103连通的内腔101中。此时，高压储油器100设置在主流路(参照图1的“47a”)上，输入端口102连接在与泵44的排出端连接的主流路47a上，输出端口103连接在与主缸20连接的主流路47a上。并且，以内腔101为基准，输入端口102和输出端口103相对而置。更具体地，高压储油器100包括用于封闭一侧开放的内腔101的开放部的盖部件110和设置在所述内腔101的阻尼部件120。
盖部件110与阻尼部件120结合并封闭内腔101的开放的一端。在所述盖部件110的内侧形成有用于与阻尼部件120结合的结合槽111。对于盖部件110和阻尼部件120通过所述结合槽111压入结合的结构，下面再进行说明。
阻尼部件120设置在内腔101中，并具有中空的圆筒形状，在阻尼部件的外周表面形成有用于连接输入端口102和输出端口103的迂回流路。所述迂回流路是通过形成在阻尼部件120的外周表面的槽122形成。如图2至图4所示，槽122向阻尼部件120的长度方向沿着外周表面隔开一定距离形成有多个。如果所述多个槽122能够设置在将阻尼部件120设置在内腔101时与输入端口102和输出端口103分别对应的位置上，则其数量可选择地增减。并且，阻尼部件120被设置成其下端部从内腔101的底面隔开一定距离，以便将流入到内腔101的制动液通过槽122来排出。即，分别与输入端口102和输出端口103连接的槽122，通过在阻尼部件120与内腔101的底面之间形成的规定的空间连接，并形成迂回流路，由此引导制动液的流动，降低从泵44排出的制动液的压力脉动。
如上所述，所述阻尼部件120与盖部件110压入结合并设置在内腔101中。作为盖部件110和阻尼部件120的结合结构，在阻尼部件120上形成有突出部121，所述突出部与形成在所述盖部件110的内侧的结合槽111形状吻合，以便与所述结合槽压入结合。虽然在图中未示出，但是作为阻尼部件120和盖部件110的结合结构的替代方案，还可以在盖部件110的下端部形成突出部，在与所述突出部相对应的阻尼部件120的位置上形成结合槽，由此可进行结合。
所述阻尼部件120可以由能够弹性变形的橡胶材质组成，以便流入高压制动液时起到缓冲作用。由此，为了进一步提高阻尼部件120的耐久性，还包括设置在阻尼部件120上的加强部件130。
加强部件130包括插入于阻尼部件120的中空部123的插入部133和从插入部133沿径向延伸并弯曲形成的支撑部131。插入部133沿长度方向形成贯穿孔，以便具有用于降低压力脉动的阻尼空间。所述插入部133的直径与中空部123的内径相同，并与阻尼部件120贴紧结合。并且，支撑部131被设置成与阻尼部件120的一端，即上表面相接，以防止加强部件130从阻尼部件120脱离。此时，在阻尼部件120的上侧形成有突出部121，其用于与盖部件110结合，对于突出部在后面进行说明，支撑部131与所述突出部121的上表面相接，并同突出部121一起与盖部件110结合。所述加强部件130由具有规定强度的钢(steel)材组成，并一体形成。
本发明的一个方面的高压储油器被设置成可形成有单独的阻尼空间，在图5中示出这样的实施例。图5是表示设置在本发明的另一个优选实施例的液压制动系统的高压储油器的剖视图。在此，与上述的附图中使用的附图标记相同的附图标记表示具有相同功能的部件。
参照图5，本实施例的高压储油器200包括：盖部件110，用于封闭一侧开放的内腔101的开放部；阻尼部件120，设置在所述内腔101中；加强部件230，设置在阻尼部件120上。
加强部件230包括插入于阻尼部件120的中空部123的插入部233和从插入部233沿径向延伸并弯曲形成的支撑部231。此时，在插入部233沿长度方向重复地形成凸部233a和凹部233b。
当所述加强部件230的插入部233插入于中空部123时，随着所述阻尼部件120的内周表面和插入部233的凸部233a贴紧，在阻尼部件120与凹部233b之间形成辅助阻尼空间232。因此，从输入端口102流入的高压的液压能够通过辅助阻尼空间232降低压力脉动。即，本实施例的高压储油器200在前面所述的实施例的高压储油器100的功能的基础上，通过辅助阻尼空间232降低压力脉动，从而能够更加有效地降低压力脉动。
下面，参照图4对通过如上所述的高压储油器100、200降低压力脉动的状态进行说明。
通过泵(图1的“44”)的泵送以高压排出的制动液，通过输入端口102传递至高压储油器100。通过输入端口102流入的制动液沿着阻尼部件120上形成的槽122，即沿着迂回流路移动，压力脉动降低之后从输出端口103排出。此时，制动液的液压不仅通过迂回流路降低其压力脉动，而且通过由橡胶材料制成的阻尼部件120缓冲冲击，从而能够进一步降低压力脉动。并且，在阻尼部件120内设置有阻尼空间(具体来说，阻尼部件的中空部空间)，因此，本实施例的高压储油器具有使脉动降低效果达到最大的优点。
如上所述，根据限定的实施例和附图对本发明进行了说明，但本发明并不限定于上述实施例和附图，本发明所属领域的技术人员在本发明的技术思想和权利要求书的均等的范围内可以进行各种修改和变形。
