具体实施方式
参考附图描述的实施例是示例性的，下面详细描述本申请的实施例。

在本申请的描述中，“多个”的含义是两个或两个以上。
下面参考附图描述根据本申请实施例的车辆制动系统1。
如图1-图11所示，根据本申请实施例的车辆制动系统1包括制动液控制总成100、连接油管300和制动主缸总成200。
制动液控制总成100包括油路块110和建压装置120，建压装置120安装于油路块110，油路块110的侧表面设有油路块端口，连接油管300的一端连接于油路块端口111。制动主缸总成200与制动液控制总成100分体设置，制动主缸总成200设有总成端口210，连接油管300的另一端连接于总成端口210，制动主缸总成200通过连接油管300与制动液控制总成100连通，制动主缸总成200和建压装置120均可驱动制动液通过油路块110输出。在本实施例中，制动主缸总成200的外周面设有总成端口。在其他实施例中，制动主缸总成200的端面设有总成端口。
举例而言，车辆制动系统1可以包括制动踏板、传感器和制动轮缸150。制动踏板与制动主缸总成200传动连接，传感器与建压装置120电连接，传感器用于检测制动踏板的运动变化，制动轮缸150与油路块110连通，制动轮缸150用于接收油路块110输出的制动液。
当制动踏板被踏下时，传感器可以检测到制动踏板的位移变化或者角度变化，例如传感器可以为位移传感器或者角度传感器，然后传感器向建压装置120发送电信号，从而控制建压装置120进行建压，将制动液压进制动轮缸150中，使制动轮缸150对车轮进行制动。
当制动踏板被踏下时，若发生车辆制动系统1没电、传感器损坏或者建压装置120损坏而导致建压装置120无法建压，制动主缸总成200会被制动踏板推动，制动主缸总成200将制动液压进制动轮缸150中，使制动轮缸150对车轮进行制动。
这样，车辆制动系统1存在两种制动方式，即一种是通过制动主缸总成200以纯机械控制方式进行制动，另一种是通过建压装置120和传感器配合以机械控制和电控制结合的方式进行制动，车辆制动系统1的制动准确性和可靠性可以得到保证。
根据本申请实施例的车辆制动系统1，通过将制动主缸总成200与制动液控制总成100分体设置，相比于相关技术中将制动主缸总成和制动液控制总成集成为一体进行安装的车辆制动系统，本申请实施例的车辆制动系统1的制动主缸总成200和制动液控制总成100各自单独布置，布置位置和安装方式更为灵活，空间利用率能够得到提高，并且拆装方便，制动主缸总成200和制动液控制总成100中的每个不需要单独占用大空间。
在本实施例中，制动主缸总成200与制动液控制总成100的分体设置为制动主缸总成200与制动液控制总成100分开并分别安装。在其他实施例中，制动主缸总成200与制动液控制总成100的分体设置可以是制动主缸总成200的缸体和油路块110的本体非一体连接，此时，制动主缸总成200通过螺纹连接等连接方式可拆卸地安装在制动液控制总成100上。其中，制动主缸总成200包括缸体和位于缸体内的活塞，活塞在缸体内运动带动制动液流动。
通过设置制动液控制总成100包括油路块110和建压装置120，建压装置120安装于油路块110，制动主缸总成200通过连接油管300与油路块110连通，制动主缸总成200和建压装置120均可驱动制动液通过油路块110输出，换言之，制动主缸总成200可以单独驱动制动液通过油路块110输出，建压装置120可以单独驱动制动液通过油路块110输出，或者制动主缸总成200和建压装置120可以单独驱动制动液通过油路块110输出。
其中，油路块110内可以设有油路，油路分别与建压装置120、制动主缸总成200和制动轮缸150连通，从而建压装置120和制动主缸总成200均可以通过油路块110向制动轮缸150输出制动液，建压装置120和制动主缸总成200均使用了油路块110内的油路，能够提高车辆制动系统1的油路集成度，降低车辆制动系统1的占用空间和加工复杂度。
另外，连接油管300的一端连接于油路块110的侧表面的油路块端口111，连接油管300的上述另一端连接于制动主缸总成200的外周面的总成端口210，连接油管300的两端分别与油路块端口111和总成端口210连通，制动主缸总成200通过连接油管300向油路块110内输出制动液。
这样，连接油管300与油路块110的连接方式更为多样，且连接油管300与制动主缸总成200的连接方式更为多样，从而油路块110、连接油管300和制动主缸总成200三者之间的布置方式更为灵活，车辆制动系统1可以根据车型进行灵活调整，车辆制动系统1的适应性低，无需针对车型重新设计车辆制动系统1，缩短了研发周期。
如此，根据本申请实施例的车辆制动系统1具有布置方式灵活、研发周期短且实用性高等优点。
根据本申请的一些具体实施例，如图1-图3所示，连接油管300的上述另一端连接于制动主缸总成200的朝向制动液控制总成100的一侧。这样，连接油管300的长度更短，降低成本与重量，且由于连接油管300的长度减小，因此制动液在连接油管300内的流阻会相应地减小。
根据本申请的一些具体实施例，如图1-图3所示，连接油管300为多个，这样，制动主缸总成200向油路块110内输出的制动液的流量更大，便于同时对车辆的多个车轮进行制动，制动效果更好，制动效率更高。
另外，如图8和图9所示，多个连接油管300的一端连接于油路块110的不同侧或者同一侧，即油路块端口111可以构造于油路块110的不同侧或者同一侧，这样，连接油管300和油路块110之间的连接方式更为多样灵活，可以在车辆制动系统1应用于不同车型时，可以根据车型及时调整油路块110和连接油管300的连接方式，提高了车辆制动系统1的适用性。
此外，多个连接油管300的上述另一端连接于制动主缸总成200的同一侧且沿制动主缸总成200的轴向间隔排布，或多个连接油管300的上述另一端连接于制动主缸总成200的不同侧，即总成端口210可以构造于制动主缸总成200的同一侧或者不同侧。这样，连接油管300和制动主缸总成200之间的连接方式更为多样灵活，可以在车辆制动系统1应用于不同车型时，根据车型及时调整制动主缸总成200和连接油管300的连接方式，提高车辆制动系统1的适用性。
根据本申请的一些具体实施例，如图4-图7所示，制动主缸总成200的外周面构造有第一管口220和第二管口230，第一管口220和第二管口230的朝向不同，连接油管300的上述另一端可选择地连接于第一管口220和第二管口230中的一个。其中，第一管口220和第二管口230可以沿制动主缸总成200的周向间隔排布。并且，总成端口210包括第一管口220和第二管口230。
举例而言，制动主缸总成200和油路块110之间的相对位置可以随车型的不同而不同，通过设置第一管口220和第二管口230，在连接油管300的上述另一端可以选择与油路块110更近的管口连接，例如，第一管口220与油路块110的间距小于第二管口230与油路块110的间距时，此时连接油管300与第一管口220连接，且第二管口230需要被封闭，以防止制动主缸总成200内的制动液由第二管口230泄漏；第一管口220与油路块110的间距大于第二管口230与油路块110的间距时，此时连接油管300与第二管口230连接，且第一管口220需要被封闭，以防止制动主缸总成200内的制动液由第一管口220泄漏。
这样，连接油管300的长度可以更短，并且，连接油管300的上述另一端与制动主缸总成200之间的连接方式更多，提高了车辆制动系统1的适用性。
根据本申请的一些具体实施例，制动主缸总成200上可以设置第一管口220和第二管口230两者之一，具体如下。
根据本申请的一些具体实施例，如图1和图2所示，制动主缸总成200和制动液控制总成100沿车身的宽度方向(即左右方向)排布，这样，制动主缸总成200和制动液控制总成100不会占用过多的车身的长度方向(即前后方向)以及高度方向(即上下方向)的尺寸。其中，制动主缸总成200和制动液控制总成100沿左右方向指的是以车尾到车头为前向的左右方向排布，在本实施例中，制动主缸总成200在左，制动液控制总成100在右。在其他实施例中，也可以是制动主缸总成200在右，制动液控制总成100在左。在另外的实施例中，制动主缸总成200和制动液控制总成100沿左右方向还可以是沿车身的其他非前后方向进行排布，比如制动主缸总成200在以车尾到车头为前向的右后方，制动液控制总成100在以车辆行驶方向为前向的左前方。
另外，通过设置第一管口220，第一管口220位于制动主缸总成200在左右方向的朝向制动液控制总成100的一侧，即连接油管300的上述另一端连接于制动主缸总成200在车身的宽度方向的朝向制动液控制总成100的一侧。这样，连接油管300的长度更短，降低成本与重量，且由于连接油管300的长度减小，因此制动液在连接油管300内的流阻会相应地减小。
根据本申请的一些具体实施例，如图3所示，制动主缸总成200和制动液控制总成100沿车身的高度方向(即上下方向)排布，且制动主缸总成200位于制动液控制总成100的正上方，这样，制动主缸总成200和制动液控制总成100不会占用过多的车身的长度方向(即前后方向)以及宽度方向(即左右方向)的尺寸，并且，在重力的作用下，制动主缸总成200内的制动液更容易通过连接油管300流到油路块110，提高了制动响应效率。在其他的实施方式中，制动主缸总成200和制动液控制总成100沿车身的高度方向(即上下方向)排布，且在竖直方向上，制动主缸总成200位于制动液控制总成100的斜上方。
另外，通过设置第二管口230，第二管口230位于制动主缸总成200的下侧，即连接油管300的上述另一端连接于制动主缸总成200的下侧。这样，连接油管300的长度更短，降低成本与重量，且由于连接油管300的长度减小，因此制动液在连接油管300内的流阻会相应地减小。
根据本申请的一些具体实施例，如图4-图7所示，制动主缸总成200的外周面构造有进液口240，进液口240位于制动主缸总成200的上侧，进液口240适于与车辆的储油装置连通，连接油管300的上述另一端和进液口240位于制动主缸总成200的外周面的不同侧。
举例而言，储油装置可以为油壶，通过设置进液口240，能够实现储油装置为制动主缸总成200补充制动液，以便于制动主缸总成200的重复多次利用，并且进液口240和连接油管300的上述另一端不位于制动主缸总成200的外周面的同一侧，这样能够避免与进液口240连通的管道和连接油管300之间发生干涉，另外，进液口240位于制动主缸总成200的上侧，并且进液口240进入的制动液在重力的作用下流入到制动主缸总成200内。
根据本申请的一些具体实施例，如图8-图11所示，油路块110的侧表面构造有出液口112，油路块110通过出液口112向制动轮缸150输出制动液。这样，出液口112也构造于油路块110的侧表面，从而出液口112不会占用油路块110的顶面与底面，提高油路块110的侧表面的利用率。
举例而言，建压装置120为活塞泵，活塞泵具有电机121，电机121安装于油路块110，电机121和出液口112位于油路块110的同一侧表面。通过将电机121和出液口112位于油路块110的同一侧表面，能够提高油路块110用于安装电机121的侧面利用率。
根据本申请的一些具体实施例，如图1-图3所示，制动液控制总成100还包括电控装置130和供油装置140。供油装置140为能够提供制动液的装置。在本实施例中，供油装置140为储油装置(例如油壶)，制动液流动的动力来源于制动主缸总成200的活塞动作，或建压装置120的活塞动作。在另外的实施例中，供油装置140可以 是包括储油装置(例如油壶)和给储油装置辅助提供液动力的动力装置。
如图2和图11所示，电控装置130安装于油路块110且与电机121分设于油路块110的相对两侧，电控装置130具有控制阀1301，控制阀1301与建压装置120电连接，控制阀1301根据车辆的制动踏板的运动变化来控制建压装置120是否驱动制动液通过油路块110输出。其中，控制阀1301可以为电磁阀。
通过设置电控装置130，电控装置130可以与传感器连接，从而获得传感器反馈的电信号，电控装置130可以根据传感器反馈的电信号计算出制动踏板的位移距离或者转动角度，能够更为准确地控制建压装置120的压力，以使车辆的制动力与司机所需的制动力相匹配，提高制动体验。
供油装置140安装于油路块110的顶面，供油装置140与活塞泵连接，用于活塞泵提高制动液。其中供油装置140和进液口240可以连接于同一个油壶，或者供油装置140和进液口240可以连接于不同油壶，再或者供油装置140直接通过进液口240为制动主缸总成200提供制动液。油路块110的底面适于与车身连接。其中，油路块110的底面可以安装于前舱的横梁400。
通过设置供油装置140，能够为活塞泵提供制动液，以便于活塞泵的反复使用，为活塞泵的下次建压制动做准备。
这样，前舱的横梁400可以对油路块110起到支撑作用，油路块110既无需悬伸在前舱内，又无需额外设置支架来制成油路块110，油路块110安装稳定，且减小了占用空间。并且，将供油装置140安装于油路块110的顶面，油路块110可以对供油装置140起到支撑作用，且供油装置140也不会与前舱的横梁400和建压装置120之间发生干涉，制动液控制总成100的布置更为方便，供油装置140的制动液可以在重力的作用下流向活塞泵，使用更为方便。
下面参考图12描述根据本申请实施例的车辆100，车辆100包括根据本申请上述实施例的车辆制动系统1。
根据本申请实施例的车辆，通过利用根据本申请上述实施例的车辆制动系统1，具有布置方式灵活、研发周期短且实用性高等优点。
