技术领域
本公开在一些实施例中涉及一种用于车辆的制动装置。
背景技术
本节中的陈述仅提供与本公开有关的背景信息，并不一定构成现有技术。
在用于车辆的制动装置中，电子液压制动装置通过行程传感器检测制动踏板的压下，然后利用液压调节器调节每个车轮的制动压力。
电子液压制动装置响应于制动情况，使控制单元驱动电机，电机进而旋转地驱动两个液压泵，以向安装在每个车轮中的车轮制动器提供制动压力。液压泵分别向两个车轮制动器提供制动压力。这里，两个液压泵由于其旋转周期而产生脉动，其中各个液压泵具有180度的相位差而引起脉动发生。为了减轻这种脉动，在电子液压制动系统中布置了脉动阻尼器。
韩国专利申请公开No.10-2015-0044342(公开于2015年4月24日，标题为Electronic Hydraulic Brake Device)公开的脉动阻尼器在其左右两侧配备有阻尼器帽。在两侧安装阻尼器帽增加了生产成本，并需要额外的组装时间，这留下了未解决的问题。
发明内容

在本说明书中，术语“左”和“右”仅用于指示某些元件在附图中示出的方向，并且本公开不限于其示出的方向和位置。
图1是根据本公开的至少一个实施例的车辆制动装置的框图。
如图1所示，用于车辆的制动装置包括主缸10、第一流动路径30a、第二流动路径30b、泵单元40、脉动阻尼器50、控制单元70和多个车轮制动器w1、w2、w3、W4中的全部或部分。
当制动踏板11被压下时，主缸10向多个车轮制动器w1、w2、w3、w4供应液压。响应于驾驶员压下制动踏板11，主缸10渐增地产生到达多个车轮制动器w1、w2、w3和W4的液压。
多个车轮制动器w1、w2、w3、w4包括用于制动车辆左后轮的第一车轮制动器w1、用于制动右后轮的第二车轮制动器w2、用于制动左前轮的第三车轮制动器w3和用于制动右前轮的第四车轮制动器w4。这里，为了便于描述，出于形式的考虑，定义了第一至第四车轮制动器w1至w4，并且第一至第四车轮制动器w1至w4的位置不限于这些定义的位置。
第一流动路径30a和第二流动路径30b连接主缸10和多个车轮制动器w1、w2、w3、w4，从而将由主缸10产生的液压供应到车轮制动器w1、w2、w3、w4。这里，第一流动路径30a被配置为向第一和第二车轮制动器w1和w2供应液压，第二流动路径30b被配置为向第三和第四车轮制动器w3和W4供应液压。
第一流动路径30a和第二流动路径30b分别包括多个阀。第一流动路径30a和第二流动路径30b包括第一牵引控制阀61a和第二牵引控制阀61b、第一高压切换阀62a和第二高压切换阀62b、第一至第四入口阀63a至63d、以及第一至第四出口阀64a至64d。
第一牵引控制阀61a和第二牵引控制阀61b可以调节从主缸10供应到泵单元40的液压。例如，第一牵引控制阀61a是能够根据来自控制单元70的控制信号打开和关闭第一流动路径30a的电磁阀。第一牵引控制阀61a和第二牵引控制阀61b布置在主缸10和泵单元40之间。第一牵引控制阀61a和第二牵引控制阀61b可以形成为常开型，用于在没有从控制单元70输入控制信号时常开。
第一高压切换阀62a和第二高压切换阀62b可以调节从储液罐供应到泵单元40的液压。当第一牵引控制阀61a和第二牵引控制阀61b关闭时，控制单元70打开第一高压切换阀62a和第二高压切换阀62b，以允许液压从储液罐直接供应到泵单元40。第一高压切换阀62a和第二高压切换阀62b可以形成为常闭型，用于在没有从控制单元70输入控制信号时常闭。
第一至第四入口阀63a至63d可以调节由驾驶员压下制动踏板11或驱动泵单元40产生并供应给车轮制动器w1、w2、w3和W4的液压。第一至第四入口阀63a至63d可以形成为常开型，用于在没有从控制单元70输入控制信号时常开。
第一至第四出口阀64a至64d是用于将供应给多个车轮制动器w1、w2、w3、w4的液压旁通回泵单元40的阀。控制单元可以打开第一至第四出口阀64a至64d，以使已经供应到多个车轮制动器w1、w2、w3、w4的液压被供应回泵单元40，然后泵单元40可以利用供应到其的液压来再生将供应到多个车轮制动器w1、w2、w3、w4的液压。第一至第四出口阀64a至64d可以形成为常闭型，用于在没有从控制单元70输入控制信号时常闭。
控制单元70基于车辆的各种行驶信息来控制泵单元40和阀。控制单元70可被设置为在车辆制动情况下产生用于车辆制动的液压制动信号和阀打开/关闭信号。这里，液压制动信号从控制单元70传输到泵单元40，作为用于使泵单元40驱动电机41以产生液压的信号。阀打开/关闭信号从控制单元70传输到阀，作为用于控制各种阀的打开和关闭的信号。控制单元70还可以确定制动系统的操作是否存在异常。
通过接收控制单元70的液压制动信号来驱动泵单元40，以分别向第一流动路径30a和第二流动路径30b提供液压。即使在主缸10没有工作时，泵单元40也可以向第一流动路径30a和第二流动路径30b提供液压，该液压可用于电子稳定控制或电子稳定程序。
脉动阻尼器50布置在第一流动路径30a和第二流动路径30b之间，并消除第一流动路径30a和第二流动路径30b之间的压差。具体地，脉动阻尼器50互连第一流动路径30a和第二流动路径30b，并且在一端包括阻尼器帽55在另一端包括支撑环53。以这种方式，脉动阻尼器50被设置成消除第一流动路径30a和第二流动路径30b之间的压力差。这减少了由从泵单元40供应的液压引起的脉动现象。
图2是示出根据本公开的至少一个实施例的车辆制动装置中泵单元40如何操作的示意图。
如图2所示，泵单元40包括电机41、偏心轴承42、第一液压泵43和第二液压泵44中的全部或部分。
电机41布置在第一流动路径30a和第二流动路径30b之间，偏心轴承42耦合到电机41。电机41由来自控制单元70的液压制动信号驱动，并且当电机41被驱动时，偏心轴承42旋转。这里，偏心轴承42偏心到电机41的一侧。
第一液压泵43安装在第一流动路径30a中，第二液压泵44安装在第二流动路径30b中。第一液压泵43和第二液压泵44由偏心轴承42驱动，以向第一流动路径30a和第二流动路径30b供应液压。当电机41旋转一次时，偏心轴承42供应的液压之间，具体是从第一液压泵43供应的液压与从第二液压泵44供应的液压之间的相位差变为180度。
图3是根据至少一个实施例的车辆制动装置的部件中的脉动阻尼器50的横截面图。图4是根据至少一个实施例的在车辆制动装置中利用第一液压泵驱动脉动阻尼器50的操作状态的示意图。图5是根据至少一个实施例的在车辆制动装置中利用第二液压泵驱动脉动阻尼器50的操作状态的示意图。
如图3至图5所示，脉动阻尼器50包括第一流动路径延伸单元54a、第二流动路径延伸单元54b、阻尼器帽55、支撑环53、气缸(未示出)、活塞51、第一弹性单元52a和第二弹性单元52b中的全部或部分。
第一流动路径延伸单元54a是从第一流动路径30a延伸的流动路径，第二流动路径延伸单元54b是从第二流动路径30b延伸的流动路径。第一流动路径延伸单元54a和第二流动路径延伸单元54b是用于在第一流动路径30a和第二流动路径30b之间布置脉动阻尼器50的流动路径延伸部。第一流动路径延伸单元54a和第二流动路径延伸单元54b可以具有相同的有效横截面积。均等化有效横截面积可以有效地减小在第一流动路径30a和第二流动路径30b中产生的脉动的振幅差。这里，有效横截面积是指脉动阻尼器50的部分的横截面积，液压油可以流过该部分。
阻尼器帽55具有用于容纳第一流动路径延伸单元54a的空间，并且与第一流动路径延伸单元54a接触。安装阻尼器帽55的位置不限于此，它可以与第二流动路径延伸单元54b接触。阻尼器帽55由具有弹性的材料制成，并且可以弹性地支撑第一弹性单元52a。阻尼器帽55还用于阻止液压油的泄漏。
支撑环53布置在第二流动路径延伸单元54b的端部。支撑环53可以由具有弹性的材料或金属材料制成。这里，支撑环53的材料可以形成为具有与阻尼器帽55的硬度相等的硬度。当由弹性材料制成时，支撑环53可以弹性地支撑第二弹性单元52b。支撑环53形成为中央中空结构。具体地，支撑环53形成有通过中空部分的流动路径，以允许液压油流动。
脉动阻尼器50包括气缸，该气缸布置在第一流动路径延伸单元54a和第二流动路径延伸单元54b之间，并且在其中具有阻尼器容纳空间(未示出)。具体地，气缸布置在阻尼器帽55和支撑环53之间。
活塞51布置在气缸中，并且根据跨第一流动路径30a和第二流动路径30b产生的液压差而线性移动。活塞51的左端和右端分别装配有第一弹性单元52a和第二弹性单元52b。第一弹性单元52a布置在活塞51和阻尼器帽55之间，以弹性地支撑它们。另外，第二弹性单元52b布置在活塞51和支撑环53之间，以弹性地支撑它们。这里，活塞51、第一弹性单元52a和第二弹性单元52b可以形成为无套筒型结构。
第一弹性单元52a和第二弹性单元52b用于在由于液压差而执行线性运动时弹性地支撑活塞51。第一弹性单元52a和第二弹性单元52b可以是弹簧。
图6是示出根据本公开的至少一个实施例的车辆制动装置的部件之中组装脉动阻尼器的过程的顺序图。
首先，如图6的(a)所示，压装或注塑(inject)支撑环53。在注塑支撑环53之后，执行图6的(b)的步骤，其中，活塞51、第一弹性部分52a和第二弹性部分52b作为子组件插入气缸(未示出)中。此后，如图6的(c)所示，组装阻尼器帽55以完成组装过程。本公开布置支撑环53来代替另一个阻尼器帽55，该阻尼器帽55通常存在，使得组装过程变得复杂。现在，在将支撑环53布置原位的情况下，提供了简化的组装过程。
如上所述，根据本公开的至少一个实施例，车辆制动装置在脉动阻尼器的一端提供了支撑环来代替阻尼器帽，从而降低了脉动阻尼器的生产成本。
另外，通过在脉动阻尼器的一端提供支撑环来代替阻尼器帽，从而简化了脉动阻尼器的组装过程，从而可以使车辆制动装置具有缩短的组装时间。
尽管出于说明性目的描述了本公开的示例性实施例，但是本领域技术人员将理解，在不脱离所要求保护的发明的思想和范围的情况下，可以进行各种修改，增加和替换。因此，为了简洁和清楚起见，已经描述了本公开的示例性实施例。本实施例的技术思想的范围不受图示的限制。因此，本领域的普通技术人员将理解，所要求保护的发明的范围不受上述明确描述的实施例的限制，而是由权利要求及其等同物限制。
