Description

用于制动钳组件的弹簧结构及制动钳组件
本申请要求2023年10月27日提交的、申请名称为“用于制动钳组件的弹簧结构及制动钳组件”的中国专利申请CN202322922098.3的优先权，上述中国专利申请的全部内容通过引用并入本申请中。
技术领域
本申请涉及车辆制动技术领域，具体提供一种用于制动钳组件的弹簧结构及制动钳组件。
背景技术
车辆的制动钳用于对车轮进行制动，从而使车辆处于减速或停车的状态。目前的制动器包括盘式制动器和鼓式制动器。以其中的盘式制动器为例，其主要包括通过轮毂轴承与车轮连接的制动盘以及能够与制动盘接触/脱离的制动卡钳，通过向制动卡钳施加外力，便可使得制动卡钳与制动盘接触的前提下，从而借助于制动卡钳与制动盘之间产生的摩擦力实现车轮的制动。相反，通过将外力去除，便可使得制动卡钳制动盘脱离，从而使得车辆解除制动。
盘式制动器的制动卡钳主要包括固定式卡钳和浮动式卡钳，以固定式卡钳为例，包含双活塞或多活塞。以六活塞定钳为例，跨置在制动盘上的六活塞定钳固定安装在车辆的转向节上，定钳本身既不能旋转也不能沿制动盘的轴向移动，六个活塞平均分置于制动盘的两侧。在实现车轮的制动时，制动总泵内的制动液经进油口进入钳体内形成的相通的油缸内，从而将钳体两侧的制动摩擦片分别压向与车轮固定连接的制动盘，基于此，便可使车辆减速或停车。六活塞定钳还配置有弹簧结构，弹簧结构在每次制动力解除之后，可以保证制动摩擦片能够从制动盘上快速稳定地回位。不过，目前的制动卡钳在制动力释放之后，由于摩擦片与制动盘之间分离不彻底因此可能会产生拖滞力矩，这可能导致制动卡钳出现拖滞现象。另外，还有部分弹簧结构所需的运行路径较长， 因而弹簧结构占用的空间较大。
相应地，本领域需要一种新的用于制动钳组件的弹簧结构来解决现有技术中的弹簧结构占用空间大或者不能将摩擦片快速回位的问题。
发明内容

在第一方面，本申请提供一种用于制动钳组件的弹簧结构，所述制动钳组件用于对车辆的车轮进行制动，所述车轮上设置有制动盘，所述制动钳组件包括能够夹设在所述制动盘两侧的摩擦片，所述摩擦片能够向靠近或远离所述制动盘的方向运动，以使所述摩擦片能够夹紧或放松所述制动盘，所述弹簧结构包括弹簧主体和设置在所述弹簧主体上的第一弹簧件与第二弹簧件，所述第一弹簧件沿所述制动盘的径向压设在所述摩擦片上，所述第二弹簧件沿所述制动盘的轴向预压在所述摩擦片上，以使所述摩擦片能够在所述第二弹簧件的作用下向远离所述制动盘的方向运动，所述第二弹簧件所在的平面与所述弹簧主体所在的平面平行。
在上述用于制动钳组件的弹簧结构的优选技术方案中，所述第一弹簧件包括与所述弹簧主体连接的支撑体、第一弯曲部和压设部，所述第一弯曲部的一端连接在所述支撑体上，所述第一弯曲部的另一端与所述压设部连接，所述压设部压设在所述摩擦片上。

在上述用于制动钳组件的弹簧结构的优选技术方案中，所述第二弹簧件包括与所述弹簧主体连接的连接部、第二弯曲部和预压部，所述第二弯曲部的一端与所述连接部连接，所述第二弯曲部的第二端与所述预压部连接，所述预压部向所述摩擦片的方向弯折，以使所述预压部预压在所述摩擦片上。
在上述用于制动钳组件的弹簧结构的优选技术方案中，所述预压部上包括若干第二弯折部，所述第二弯折部向所述摩擦片的方向弯折。
在上述用于制动钳组件的弹簧结构的优选技术方案中，所述弹簧主体上还设置有安装部，所述弹簧主体通过所述安装部安装在所述制动钳组件上。
在上述用于制动钳组件的弹簧结构的优选技术方案中，所述第一弹簧件和/或所述第二弹簧件与所述弹簧主体可拆卸连接。
在上述用于制动钳组件的弹簧结构的优选技术方案中，所述弹簧主体上设置有圆孔或腰圆孔的一种，所述第一弹簧件和/或所述第二弹簧件上设置有所述圆孔或所述腰圆孔中的另一种，以使所述第一弹簧件和/或所述第二弹簧件固定在所述弹簧主体上。
本申请还提供一种制动钳组件，所述制动钳组件包括上述技术方案中任一项所述的用于制动钳组件的弹簧结构。
在上述制动钳组件的优选技术方案中，所述制动钳组件上还设置有活塞，所述驱动件能够驱动所述活塞挤压摩擦片以使所述摩擦片夹紧所述制动盘，所述活塞的内径与所述活塞外径的比值在20％-45％之间。
在采用上述技术方案的情况下，本申请的弹簧结构包括弹簧主体和设置在弹簧主体上的第一弹簧件与第二弹簧件，第一弹簧件沿制动盘的径向压设在摩擦片上，无论摩擦片向靠近还是远离制动盘的方向运动，第一弹簧件都能与摩擦片进行摩擦抵接，从而控制摩擦片的运行速度，进而避免摩擦片在车辆运动时窜动从而撞击其周边零件而产生振动噪音，第二弹簧件沿制动盘的轴向预压在摩擦片上，当活塞将摩擦片向制动盘方向推动时，第二弹簧件预压在摩擦片上的力逐渐增加，当活塞不再受到驱动力时，活塞自行回到初始位置，摩擦片不再受活塞的推动作用，此时第二弹簧件施加在摩擦片上的预压力推动摩擦片向远离制动盘的方向运动，从而使摩擦片回到初始位置。将第二弹簧件所在的平面设置为与弹簧主体所在的平面平行，此时第二弹簧件设置在弹簧主体与摩擦片之间，第二弹簧件对摩擦片的推动仍在弹簧主体与摩擦片之间， 上述设置能够降低第二摩擦片占用的空间，同时还能避免其他部件对第二弹簧件造成干扰。

如图1-5所示，为解决现有技术中的弹簧结构占用空间大或者不能将摩擦片快速回位的问题，本申请的制动钳组件1包括弹簧结构10，为了便于描述弹簧结构10在制动钳组件1中的作用，需要先对制动钳组件1进行介绍，制动钳组件1用于对车辆的车轮进行制动，车轮上设置有制动盘(图中未示出)，如图1、2、3所示，制动钳组件1包括摩擦片14和活塞15，活塞15设置在摩擦片14的外侧，能够驱动摩擦片14向靠近制动盘的方向运动，当外部对活塞15施加驱动力时，活塞15推动摩擦片14向靠近制动盘的方向运动，从而使摩擦片14与制动盘摩擦接触进而实现对制动盘的制动以及对车轮的制动，当对活塞15的驱动力消失时，活塞15自动向远离制动盘的方向缩回，此时摩擦片14在本申请的弹簧结构10的作用下向远离制动盘的方向运动直到摩擦片14与制动盘不再接触，制动钳组件1取消对车轮的制动。本申请的弹簧结构10主要用于控制摩擦片14向远离制动盘的方向运动，如图1所示，弹簧主体11上设置有安装部111，弹簧主体11通过安装部111固定在制动钳组件1上，弹簧结构10包括弹簧主体11和设置在弹簧主体11上的第一弹簧件12与第二弹簧件13，第一弹簧件12沿制动盘的径向压设在摩擦片14上，无论摩擦片14向靠近还是远离制动盘的方向运动，第一弹簧件12都能与摩擦片14进行摩擦抵接，从而控制摩擦片14的运行，进而避免摩擦片14在车辆运动时窜动从而撞击其周边零件而产生振动噪音，第二弹簧件13沿制动盘的轴向预压在摩擦片14上，当活塞15将摩擦片14向制动盘方向推动时，第二弹簧件13预压在摩擦片14上的力逐渐增加，当活塞15不再受到驱动力时，活塞15自行回到初始位置，摩擦片14不再受活塞15的推动作用，此时第二弹簧件13施加在摩擦片14上的预压力推动摩擦片14向远离制动盘的方向运动，从而使摩擦片14回到 初始位置。本申请将第二弹簧件13所在的平面设置为与弹簧主体11所在的平面平行，此时第二弹簧件13设置在弹簧主体11与摩擦片14之间，第二弹簧件13对摩擦片14的推动的整体运动过程仍在弹簧主体11与摩擦片14之间进行，上述设置能够降低第二摩擦片14在制动前组件1内的占用空间，同时还能避免其他部件对第二弹簧件13造成干扰。
如图4所示，在一种优选的实施方式中，第一弹簧件12包括与弹簧主体11连接的支撑体121、第一弯曲部122和压设部123，第一弯曲部122的一端连接在支撑体121上，第一弯曲部122的另一端与压设部123连接，压设部123压设在摩擦片14上，压设部123的端部还设置有第一弯折部1231，第一弯折部1231向支撑体121的方向弯折。弧形的第一弯曲部122将压设部123与支撑体121连接，压设部123对摩擦片14进行抵压，当摩擦片14在制动的径向出现震动时，压设部123会受到摩擦片14给的力，由于压设部123与支撑体121通过弧形的第一弯曲部122连接，因此弧形的设置能够给压设部123一定弹力，从而避免压设部123在突然受力下折断。第一弯曲部122能够增加第一弹簧件12受力的稳定性。另外，第一弯折部1231设置在压设部123的端部，当压设部123受到向支撑体121方向的力时，压设部123会向支撑体121的方向运动，当压设部123运动到一定程度后第一弯折部1231与支撑体121接触从而对压设部123受到的力进行缓冲，避免压设部123继续运动，进而避免压设部123在受力较大的情况下突然折断。
在另一种优选的实施方式中，第二弹簧件13包括与弹簧主体11连接的连接部131、第二弯曲部132和预压部133，第二弯曲部132的一端与连接部131连接，第二弯曲部132的第二端与预压部133连接，预压部133向摩擦片14的方向弯折，以使预压部133预压在摩擦片14上，预压部133上包括若干第二弯折部1331，第二弯折部1331向摩擦片14的方向弯折。第二弹簧件13包括第二弯曲部132，由于第二弯曲部132呈圆弧设置，当摩擦片14受到的驱动力去除后，圆弧状的第二弯折部1331能够帮助预压部133回弹并将摩擦片14推至初始位置，同时，圆弧状的第二弯折部1331还能增加第二弹簧件13推动摩擦片14的距离。另外，为了避免预压部133在运动过程中突然受力而折断，在预压部133上设 置多个第二弯折部1331。
在一种优选的实施方式中，第一弹簧件12和/或第二弹簧件13与弹簧主体11可拆卸连接。以下以第二弹簧件13与弹簧主体11可拆卸连接，第二弹簧件13固定连接在弹簧主体11上为例进行介绍，当第二弹簧件13与弹簧主体11可拆卸连接时，弹簧主体11上设置有圆孔或腰圆孔的一种，第二弹簧件13上设置有圆孔或腰圆孔中的另一种，铆钉穿过圆孔铆接后变形涨满腰圆孔，实现第二弹簧件13和弹簧主体11的防转固定，第一弹簧件12可拆卸连接在弹簧主体11上的设置方式与第二弹簧件13可拆卸连接在弹簧主体11上的设置方式同理，此处不再一一赘述。
综上所述，弹簧结构10包括弹簧主体11和设置在弹簧主体11上的第一弹簧件12与第二弹簧件13，第一弹簧件12沿制动盘的径向压设在摩擦片14上，无论摩擦片14向靠近还是远离制动盘的方向运动，第一弹簧件12都能与摩擦片14进行摩擦抵接，从而控制摩擦片14的运行速度，进而避免摩擦片14在车辆运动时窜动从而撞击其周边零件而产生振动噪音，第二弹簧件13沿制动盘的轴向预压在摩擦片14上，当活塞15将摩擦片14向制动盘方向推动时，第二弹簧件13预压在摩擦片14上的力逐渐增加，当活塞15不再受到驱动力时，活塞15自行回到初始位置，摩擦片14不再受活塞15的推动作用，此时第二弹簧件13施加在摩擦片14上的预压力推动摩擦片14向远离制动盘的方向运动，从而使摩擦片14回到初始位置。将第二弹簧件13所在的平面设置为与弹簧主体11所在的平面平行，此时第二弹簧件13设置在弹簧主体11与摩擦片14之间，第二弹簧件13对摩擦片14的推动的整体运动过程仍在弹簧主体11与摩擦片14之间进行，上述设置能够降低第二摩擦片14在制动前组件1内的占用空间，同时还能避免其他部件对第二弹簧件13造成干扰。
需要说明的是，上述实施方式仅仅用来阐述本申请的原理，并非旨在与限制本申请的保护范围，在不偏离本申请原理的条件下，本领域技术人员能够对上述结构进行调整，以便本申请能够应用于更加具体的应用场景。
此外，本申请还提供了一种制动钳组件1，该制动钳组件1 具有上述任一实施方式中的用于制动钳组件1的弹簧结构10。为了改善制动钳组件1上的活塞15对摩擦片14的推动效果，如图5所示，将活塞15的内径B与活塞15外径A的比值设置在20％-45％之间，此时活塞15的壁厚大，有利于提高活塞的刚度，减少活塞变形程度，进而利于增大制动盘与摩擦片15之间的间隙，进一步提高低拖滞效果。
至此，已经结合附图所示的优选实施方式描述了本申请的技术方案，但是，本领域技术人员容易理解的是，本申请的保护范围显然不局限于这些具体实施方式。在不偏离本申请的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本申请的保护范围之内。
