Description

自适应横向稳定装置及使用装置的车辆悬架系统
技术领域
本发明涉及一种自适应横向稳定装置及使用该自适应横向稳定装置的悬架系统。
背景技术
目前,车辆侧倾是影响乘坐舒适性和驾驶安全性的重要因素之一,弯道侧倾及高速侧倾也是导致车辆侧翻的重要因素,直接危及人身安全。近年来,车辆主动抗侧倾技术得到了较快的发展,其中以主动横向稳定杆技术最为突出,如申请号201080064543.X的专利所公开的一种稳定器系统,该稳定器系统包括桥接在左右车轮之间的一对稳定杆构件,这一对稳定杆构件通过作动器以能够相对旋转的方式连接,作动器包括作为驱动源的电动机以及与电动机传动连接的减速器,稳定杆构件传动连接在减速器的输出端上,且电容及其上控制连接有电子控制单元(ECU),电子控制单元对作动器的动作进行控制,以作为与作动器中电动机对应的驱动电路的逆变器及以具备CPU、ROM、RAM等的计算机为主题的控制器,因此市售的用于乘用车、跑车及越野车的主动稳定杆系统结构复杂、成本较高,且不利于安装调试。
发明内容
本发明的目的是提供一种结构简单、控制难度小的自适应横向稳定装置,同时还提供了一种使用该自适应横向稳定装置的车辆悬架系统。
为了实现以上目的,本发明中自适应横向稳定装置的技术方案如下:
一种自适应横向稳定装置,包括用于随车架左倾时相对正转、随车架右倾时相对反转的左、右稳定杆构件,左、右稳定杆构件左右对称布置,所述左、右稳定杆构件之间装配有用于在正转时从正向泵口出油、在反转时从反向泵口出油的泵式扭转作动器,泵式扭转作动器的壳体和转子分别止旋装配在左、右稳定构件的相对端上,并在泵式扭转作动器的正向泵口上通过活塞缸连接有左空气弹簧,在泵式扭转作动器的反向泵口上通过活塞缸连接有右空气弹簧,活塞缸的内腔被浮动活塞隔设为与对应空气弹簧气室连通的动作气腔以及与对应泵口连通的控制油腔。
所述泵式扭转作动器的转子包括止旋连接在对应稳定杆构件上的转轴以及转轴上止旋装配的转轮,所述转轮为齿轮或叶轮。
所述转轮有两个以上、并沿转轴的轴向间隔布置。
所述泵式扭转作动器为液压作动器。
本发明中车辆悬架系统的技术方案如下:
一种车辆悬架系统,包括浮动装配在车桥上的车架以及装配在车架底部的自适应横向稳定装置,所述自适应横向稳定装置包括用于随车架左倾时相对正转、随车架右倾时相对反转的左、右稳定杆构件,左、右稳定杆构件左右对称布置,所述左、右稳定杆构件之间装配有用于在正转时从正向泵口出油、在反转时从反向泵口出油的泵式扭转作动器,泵式扭转作动器的壳体和转子分别止旋装配在左、右稳定构件的相对端上,并在泵式扭转作动器的正向泵口上通过活塞缸连接有装配在车桥左端和车架之间的左空气弹簧,在泵式扭转作动器的反向泵口上通过活塞缸连接有装配在车桥右端和车架之间的右空气弹簧,活塞缸的内腔被浮动活塞隔设为与对应空气弹簧气室连通的动作气腔以及与对应泵口连通的控制油腔。
所述泵式扭转作动器的转子包括止旋连接在对应稳定杆构件上的转轴以及转轴上止旋装配的转轮,所述转轮为齿轮或叶轮。
所述转轮有两个以上、并沿转轴的轴向间隔布置。
所述泵式扭转作动器为液压作动器。
本发明在左、右稳定杆构件之间装配有泵式扭转作动器,泵式扭转作动器的壳体和转子分别止旋装配在左、右稳定构件的相对端上,并在泵式扭转作动器的正向泵口上通过活塞缸连接有左空气弹簧,在泵式扭转作动器的反向泵口上通过活塞缸连接有右空气弹簧,活塞缸的内腔被浮动活塞隔设为与对应空气弹簧连通的动作气腔以及与对应泵口连通的控制油腔,在使用过程中,当车架随车身左倾时,左、右稳定杆构件会相对正转,同时在泵式扭转作动器的壳体和转子在左右稳定杆的带动下,使得泵式扭转作动器正转,以使得泵式扭转作动器向与左空气弹簧相邻的活塞缸的控制油腔注油,该活塞缸在控制油腔注油增压的情况下,通过浮动活塞压缩动作气腔,使得动作气腔内气压增大,阻止左空气弹簧中气体外泄,从而提高了左空气弹簧的刚度,抑制车架随车身左倾;反之,当车架随车身右倾时,泵式扭转作动器翻转而使得右空气弹簧刚度提高,从而提高了右空气弹簧的刚度,抑制车架随车身右倾,因此本发明通过左、右稳定杆构件来带动泵式扭转作动器正转或反转,再通过泵式扭转作动器的正转或反转来向车架侧倾方向增压,以提高车架侧倾方向对应空气弹簧的刚度,从而通过车辆悬架系统行驶过程中稳定杆和空气弹簧的联动来实现抑制车身侧倾的问题,使得自适应横向稳定装置的结构简单、控制难度小。
附图说明
图1是本发明客车实施例中流体控制部分的原理示意图;
图2是本发明客车实施例中稳定杆和泵式扭转作动器的连接结构示意图;
图3是本发明客车实施例的结构示意图。
具体实施方式
本发明中客车的实施例:如图1、图2和图3所示,该客车包括左车轮1、右车轮2、桥接在左车轮1和右车轮2之间的车桥3、浮动装配在车桥3上的车架4、连接在左车轮1上的左悬架5、连接在右车轮2上的右悬架6以及装配在车架4底部的自适应横向稳定装置,自适应横向稳定装置包括固定在车桥3左端的左空气弹簧71、固定在车桥3右端的右空气弹簧72、连接在左悬架5上的左稳定杆构件73、连接在右车轮2上的右稳定杆构件74、连接在左稳定杆构件73和右稳定杆构件74之间的泵式扭转作动器75、连通在泵式扭转作动器75正向泵口751上的左活塞缸76以及连通在泵式扭转作动器75反向泵口752上的右活塞缸77,其中左活塞缸76和右活塞缸77的内腔均被浮动活塞70隔设为控制油腔79和动作气腔78,左活塞缸76的控制油腔79通过油管8连通在泵式扭转作动器75的正向泵口751上,左活塞缸76的动作气腔78通过气管9连通在左空气弹簧71上,而右活塞缸77的控制油腔79通过油管8连通在泵式扭转作动器75的反向泵口752上,右活塞缸77的动作气腔78通过歧管连通在右空气弹簧72上。左空气弹簧71的顶部限位装配在车架4左侧,右空气弹簧72的顶部限位装配在车架4右侧。
泵式扭转作动器75为液压式齿轮作动器,泵式扭转作动器75的转子包括止旋连接在对应稳定杆构件上的转轴753以及转轴753上止旋装配的转轮754,该转轮754为齿轮,转轮754有两个、并沿转轴753轴向间隔布置。
本实施例中车辆悬架系统在行驶过程中,当车辆向右转弯,而车身向左侧侧倾时,左空气弹簧71受压,与左空气弹簧71连接的左活塞缸76的动作气腔78压力增大;右空气弹簧72受拉,与右空气弹簧72连接的活塞缸的动作气腔78压力减小,同时左稳定杆构件73和右稳定杆构件74随车架4左倾而相对的逆时针正转,带动泵式扭转作动器75的转子和壳体相对正转,通过向左活塞缸76中注油而使得左空气弹簧71增压,从而在泵式扭转作动器75的正向泵口751和反向泵口752之间的压差将形成抑制车身左倾的反力矩。
反之,当车辆向左转弯,而车身向右侧侧倾时,右空气弹簧72受压,与右空气弹簧72连接的右活塞缸77动作气腔78压力增大;左空气弹簧71受拉,与左空气弹簧71连接的左活塞缸76动作气腔78压力减小,该工况下通过油路连接使泵式扭转作动器75的转子在左稳定杆构件73和右稳定杆构件74的作用下顺时针反转,此时,在泵式扭转作动器75的正向泵口751和反向泵口752之间的压差将形成抑制车身右倾的反力矩。
当车身侧倾程度增大时,泵式扭转作动器75的转子转动幅度也随之增大,左活塞缸76或右活塞缸77的控制油缸内的油液将推动浮动活塞70增加该侧空气弹簧内的气体体积,空气弹簧的刚度将增大,该自适应横向稳定装置的刚度也将增大,车身被抬起,从而实现大侧倾,大刚度的特性;当车身侧倾较小时,泵式扭转作动器75的转子幅度也随之减小,对应的正向泵口751和反向泵口752之间的压差很小,自适应横向稳定装置近似于断开状态,从而提升车辆的通过性和乘坐舒适性。
在上述实施例中,泵式扭转作动器是液压式齿轮作动器,在其他实施例中,泵式扭转作动器的转子也可以是叶轮、凸轮等,而泵式扭转作动器也可以是气泵。
在上述实施例中,泵式扭转作动器的转轴上同轴设置有两个转轮,在其他实施例中,转轮的个数也可以适当的减少或增多。
本发明中自适应横向稳定装置的实施例,本实施例中自适应横向稳定装置的结构与上述实施例中自适应横向稳定装置的结构相同,因此不再赘述,而自适应横向稳定装置不但可以使用在车辆悬架系统上,还可以使用在其他装置的行走机构上。
