下面参考图1-图6描述根据本发明实施例的液压衬套组件100。
如图1所示,根据本发明实施例的液压衬套组件100包括第一液压衬套1和连通组件,第一液压衬套1具有第一液压腔11,连通组件与第一液压腔11连通,以使第一液压腔11内的液体介质能进入到连通组件,以及连通组件内的液体介质能进入到第一液压腔11。
结合图1和图2所示,以车辆的悬架总成上设置液压衬套组件100进行说明,液压衬套是一种在机械设备中广泛使用的减震元件,主要用于吸收和 减少设备运行过程中产生的振动和冲击,保护设备的关键部件,提高其工作性能和使用寿命。液压衬套内部通常包含有液压油(也即液体介质),当受到外力作用时,通过液压油在液压衬套内部的运动产生阻尼力,从而达到缓冲减震的效果。这种衬套具有良好的动态响应特性和可调性,能适应各种复杂工况下的减震需求。在汽车工业中,液压衬套常用于悬挂系统、发动机和变速箱支承等部位,可以有效降低车辆行驶过程中的震动和噪音,提升驾乘舒适性。
本示例中,第一液压衬套1内的液体介质能进入到连通组件,连通组件内的液体介质能进入到第一液压腔11,在车辆受到大幅值冲击载荷的情况下,第一液压衬套1内封装的液体可受压流出,可减弱冲击感。在高频率外部载荷激励下,该减振系统可弱化高频动态硬化,保证动刚度在较低范围,提高车辆舒适性。在某些工况下第一液压衬套1的液体介质可全部受迫流出,这时排空液体的第一液压衬套1相应的体积刚度最低,可带来了更低的动刚度,有效满足极端工况的性能要求。这里,高频率外部载荷是指在机械或结构系统运行过程中,频繁、快速且周期性变化的负荷或者力的作用。例如,在精密仪器、航空飞行器、高速列车、精密机床、某些特定类型的振动试验设备等场合,由于高速运动、高频振动、瞬态冲击等因素,可能会使系统承受高频率外部载荷。对于这种情况,使用如液压衬套这样的高性能减震元件就显得尤为重要。液压衬套能够有效地吸收并分散这些高频率载荷,降低其对主体结构或关键部件的影响,防止过度疲劳、磨损甚至损坏,确保系统的稳定运行和长寿命。
另外,结合图1所示,液压衬套一般包括衬套内管13、衬套外管12和设置在衬套内管13和衬套外管12之间的弹性件14,当第一液压衬套1受到载荷冲击时会压缩弹性件14,并能将第一液压衬套1内的液体介质挤出,而当载荷冲击消失后,弹性件14恢复形变,在负压的作用下,液体介质可以重新流入到第一液压衬套1内,由此,液体介质在流通通道内的来回流动带来的摩擦损失、惯性损失及局部损失能有效衰减振动能量。
由此,根据本发明实施例的液压衬套组件100,通过使得第一液压衬套1的第一液压腔11与连通组件连通,可以使得第一液压腔11内的液体介质受到冲击载荷时流出,以及在冲击载荷消失后回流,可减弱乘客冲击感,在高频率外部载荷激励下,液体介质在流通通道内的来回流动带来的摩擦损失、惯性损失及局部损失能有效衰减振动能量,从而提高减振效果,甚至于,第一液压衬套1的液体介质可全部受迫流出,这时排空液体的第一液压衬套1相应的体积刚度最低,可带来了更低的动刚度,有效满足极端工况的性能要求。
在本发明的一些实施例中,如图1-图4所示,连通组件包括第一连通管21,第一连通管21的端部安装在第一液压衬套1的外表面,且与第一液压腔11连通。也就是说,可以通过设置第一连通管21与第一液压衬套1的第一 液压腔11连通,结构简单,并且,第一连通管21一般为细长的管状,液体介质在第一连通管21内的来回流动是能更好地带来摩擦损失、惯性损失及局部损失,从而能更有效衰减振动能量,从而提高减振效果。另外,还可以根据实际地需求对第一连通管21的长度进行设计,从而能更好地满足实际应用。
在本发明的一些实施例中,如图1-图4所示,连通组件还包括储液罐23,储液罐23与第一连通管21连通。也就是说,第一液压腔11内的液体介质可以沿着第一连通管21进入到储液罐23内,可以理解地是,储液罐23内可以存储有液体介质,可以较好地保证第一连通管21两端的负压状态,也即,在未承受载荷冲击的状态下,储液罐23内的液体介质能使得第一液压腔11内的液体介质稳定地保持在第一液压腔11内,从而使得第一液压衬套1保持一定的动刚度。
并且,储液罐23内也可以存储有充足的液体介质,在一些工况下,可以通过驱动泵将储液罐23内的液体介质朝向第一液压腔11输送,从而满足第一液压衬套1的减振需求。
在本发明的一些实施例中,如图2-图6所示,连通组件还包括第二连通管22,第二连通管22的端部安装在第一液压衬套1的外表面,且与第一液压腔11连通。也就是说,通过增加设置第二连通管22,可以较好得提高第一液压腔11内的液体介质流入和流出的效率。
可选地,结合图4所示,第一连通管21与第一液压衬套1连通的位置为第一位置,第二连通管22与第一液压衬套1连通的位置为第二位置,第一位置和第二位置位于液压衬套中轴线的径向两侧。由此,在增加设置第二连通管22后,由于第一位置和第二位置位于液压衬套中轴线的径向两侧,可以使得第一液压腔11内的液体介质可以均匀地从第一液压腔11内流出或者流入,可以提高第一液压衬套1的稳定性。
在一些示例中,第一液压衬套1内具有两个第一液压腔11,第一连通管21与一个第一液压腔11连通,第二连通管22可以与另一个第一液压腔11连通。
在一些示例中,连通组件还可以包括第三连通管,甚至于还可以包括第四连通管,这里,仅以连通组件包括有第一连通管21和第二连通管22进行举例,但本申请并不对数量进行限制。
在本发明的一些实施例中,如图1所示,连通组件还包括储液罐23,第一连通管21和第二连通管22通过储液罐连通。
在一个示例中,第一液压腔11内的液体可以从第一连通管21进入到储液罐23,然后经储液罐23再经第二连通管22回流至第一液压腔11内,由此,通过液体介质的来回流动是能更好地带来摩擦损失、惯性损失及局部损失,从而能更有效衰减振动能量,从而提高减振效果。
在一个示例中,第一液压腔11内的液体可以同时从第一连通管21和第 二连通管22进入到储液罐23内,从而能够快速地改变第一液压衬套1的动刚度。
在本发明的一些实施例中,如图2、图5和图6所示,液压衬套组件100还包括:第二液压衬套3,第二液压衬套3具有第二液压腔31,第一液压腔11和第二液压腔31通过连通组件连通。由此,以车辆的悬架总成的左侧液压衬套和右侧液压衬套为例,其中,左侧液压衬套可以为第一液压衬套1,第二液压衬套3可以为右侧液压衬套,在车辆受到大幅值冲击载荷的情况下,单侧液压衬套内封装的液体可受压经过联通管流入另外一侧液压衬套的液体腔室,可减弱冲击感。
在一个示例中,连通组件包括第一连通管21,第一液压腔11和第二液压腔31通过第一连通管21连通。
在一个示例中,如图5和图6所示,连通组件包括第一连通管21和第二连通管22,第一连通管21的两端分别与第一液压腔11和第二液压腔31连通,第二连通管22的两端分别与第一液压腔11和第二液压腔31连通。
在一个示例中,如图2所示,连通组件包括第一连通管21、第二连通管22和储液罐23,第一连通管21的两端分别与第一液压腔11和第二液压腔31连通,第二连通管22的两端分别与第一液压腔11和第二液压腔31连通,并且,第一连通管21和第二连通管22还均与同一个储液罐23连通。
在一个示例中,连通组件包括第一连通管21、第二连通管22和两个储液罐23,第一连通管21的两端分别与第一液压腔11和第二液压腔31连通,第二连通管22的两端分别与第一液压腔11和第二液压腔31连通,并且,第一连通管21还与一个储液罐23连通,第二连通管22还与另一个储液罐23连通。
在本发明的一些实施例中,如图1所示,第一液压衬套1包括衬套外管12、衬套内管13、弹性件14和导向组件15,衬套内管13设置在衬套外管12内,弹性件14设置在衬套外管12和衬套内管13之间,导向组件15设置在衬套外管12和衬套内管13之间,用于引导衬套外管12和衬套内管13之间活动方向。由此,通过在第一液压衬套1内设置导向组件15,可以较好地限定出衬套内管13和衬套外管12之间的相对活动方向,能使得第一液压腔11内的液压介质稳定的流出第一液压腔11,也能使得液压介质回流至第一液压腔11时,第一液压衬套1较为稳定。
可选地,第二液压衬套3也可以包括衬套外管12、衬套内管13、弹性件14和导向组件15,由于第二液压衬套3的结构以及原理与第一液压衬套1完全相同,因此,这里不做赘述。
本发明还提出一种具有上述实施例的液压衬套组件100的悬架总成。
根据本发明实施例的悬架总成包括:悬架200和安装在悬架200上的液压衬套组件100,通过设置上述实施例的液压衬套组件100,可以使得悬架总成具备较好地抵抗振动的能力。
