Description

轮毂夹持装置
本申请要求于2017年09月08日提交中国专利局、申请号为201721154833.9、申请名称为“轮毂夹持装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及汽车技术领域，尤其涉及一种轮毂夹持装置。
背景技术
在汽车维修的过程中(如，四轮定位、ADAS校准过程中)，需要在轮毂上安装各种辅助设备。而现有的轮毂夹持装置采用的夹持方式为单螺母锁紧方式。即，依靠一根螺杆和一个螺母，在需要夹持辅助设备时通过正向扭转螺杆，带动螺母移动，从而实现单个螺母主动移动夹持住辅助设备；在需要卸下辅助设备时，将螺杆反向扭转，位于螺母与螺杆之间的弹簧会将螺杆与螺母弹开以实现主动松脱。
在实现本申请的过程中，发明人发现现有技术至少存在以下问题：目前的单螺母锁紧方式存在辅助设备不易在轮毂夹持装置上安装和拆卸的弊端。具体而言，依靠单边螺母锁紧时，由于弹簧的存在，导致螺母的受力不均，使得轮毂夹持装置的夹紧中心与中心孔不在一个基准面上，从而使得辅助设备不易插入轮毂夹持装置的中心孔。同样的，在进行拆卸的过程中，由于弹簧作用力不均匀，导致两边弹开的距离不同，从而使得安装于中心孔的辅助设备很难拆卸下来。

可以理解的是，在其它一些实施例中，所述第一螺母12和第二螺母13可以是同一种螺母，在安装于所述螺杆14时，其安装方向相反。
所述螺杆14包括第一螺纹部141、第二螺纹部142、连接部143和把手144。所述第一螺纹部141的一端与所述第二螺纹部142的一端固定连接，所述第二螺纹部142的另一端与所述连接部143的一端固定连接，所述把手144固定于所述连接部143的另一端。
所述第一螺纹部141和第二螺纹部142均呈圆柱状，并且所述第一螺纹部141和第二螺纹部142的外侧面均具有螺纹。所述第一螺纹部141的螺纹沿第一旋转方向设置，所述第二螺纹部142的螺纹沿第二旋转方向设置；并且所述第一旋转方向和第二旋转方向的方向相反。所述第一螺纹部141的螺纹和第二螺纹部142的螺纹的螺距相等。
所述第一螺母12套设于所述螺杆14的第一螺纹部141。当所述螺杆14旋转时，所述第一螺母12可相对于所述螺杆14转动，并且在该转动过程中，所述第一螺母12沿所述螺杆14的轴向移动。所述第二螺母13套设于所述螺杆14的第二螺纹部142。当所述螺杆14旋转时，所述第二螺母13可相对于所述螺杆14转动，并且在该转动过程中，所述第二螺母13沿所述螺杆14的轴向移动。由于所述第一螺纹部141的螺纹和第二螺纹部142的螺纹旋转方向相反并且螺距相等，在所述螺杆14旋转的过程中，所述第一螺母12和第二螺母13相互靠近或相互远离。
在本实施例中，当所述螺杆14沿第一旋转方向转动时，所述第一螺母12和第二螺母13相互靠近；所述螺杆14沿第二旋转方向转动时，所述第一螺母12和第二螺母13相互远离。需将所述辅助设备安装于所述轮毂夹紧装置100时，先将辅助设备的安装轴插入所述安装孔111内，然后沿第一旋转方向转动所述螺杆14。由于所述第一螺纹部141的螺纹和第二螺纹部142的螺纹的螺距相等，所述第一螺母12和第二螺母13的运动方向相反，并且运动距离相等，使得所述第一螺母12和第二螺母13同步产生挤压力将该辅助设备安装轴锁紧固定。
需将所述辅助设备从所述轮毂夹紧装置100上拆卸下时，沿第二旋转方向转动所述螺杆14，使得所述第一螺母12和第二螺母13相互远离。由于所述第一螺纹部141的螺纹和第二螺纹部142的螺纹的螺距相等，所述第一螺母12和第二螺母13的运动方向相反，并且运动距离相等。待第一螺母12和第二螺母13移动至一定位置时，所述第一螺母12和第二螺母13对该辅助设备 安装轴的挤压力消失。此时，可将该辅助设备安装轴从安装孔111中抽出，从而完成拆卸。
所述安装组件10还包括第一挡板15和第二挡板16，所述第一挡板15设置于所述第一螺纹部141的另一端，所述第二挡板16设置于所述第二螺纹部142的另一端。所述第一挡板15和第二挡板16均起到限位作用，用于防止在旋转所述螺杆14的过程中，所述第一螺母12和第二螺母13从所述螺杆14上脱离。
在本实施例中，所述第一螺母12和第二螺母13均设置有限位块(图未标示)，所述收容腔112的内侧面设置有限位槽(图未标示)，所述限位槽与所述收容腔112的中心线平行。所述第一螺母12的限位块和第二螺母13的限位块均嵌入所述限位槽中，并可在所述限位槽内滑动。此结构设计用于防止在所述螺杆14旋转时，带动所述第一螺母12和第二螺母13一起旋转(即，在所述螺杆14相对于所述基体11旋转时，所述第一螺母12和第二螺母13不旋转，而是沿所述螺杆14的轴向方向移动)。
在本实施例中，所述限位块可以为一螺栓或螺丝，所述第一螺母12和第二螺母13的侧面均设置有螺纹孔，该螺栓或螺丝的一端旋入螺纹孔，另一端凸出于所述第一螺母12和第二螺母13的侧面起到限位作用。
可以理解的是，在其它一些实施例中，所述第一螺母12和第二螺母13可以均为六角螺母，所述收容腔112的截面形状为六边形，用于防止所述第一螺母12和第二螺母13相对于所述基体11转动(即，所述第一螺母12和第二螺母13与所述收容腔112之间具有限位结构，该限位结构用于防止所述第一螺母12和第二螺母13相对于所述基体11转动)。
请参图5，所述支架20包括第一安装部21、第二安装部22、连接杆23、螺纹杆24和转动把手25。所述连接杆23共有两个，并且其中一个连接杆23的一端与另一连接杆23的一端固定连接，其中一个连接杆23的另一端与另一连接杆23的另一端固定连接。两个所述连接杆23相互平行。所述第一安装部21分别套设于两个所述连接杆23的一端，并可在两个所述连接杆23上滑动；所述第二安装部22分别套设于两个所述连接杆23的另一端，并可在两个所述连接杆23上滑动。所述第一安装部21设置有第一螺纹孔(图未示)，第二安装部22设置有第二螺纹孔(图未示)，所述螺纹杆24分别穿过所述第一螺纹 孔和第二螺纹孔。
所述转动把手25固定于所述螺纹杆24的一端，并且转动所述转动把手25可使得所述螺纹杆24旋转。在此旋转过程中，所述第一安装部21和第二安装部22沿两个所述连接杆23相互靠近或远离。所述第一安装部21上设置有用于卡住轮毂的第一卡合柱211，并且所述第一卡合柱211共有两个。所述第二安装部22上设置有用于卡住轮毂的第二卡合柱221，并且所述第二卡合柱221共有两个。
请一并参阅图6，通过旋转所述螺纹杆24，使所述第一安装部21和第二安装部22相互靠近，可使得第一卡合柱211和第二卡合柱221共同夹持住轮毂，从而使得所述支架20与该轮毂固定连接。
本申请实施例的轮毂夹持装置100中将两个螺母(12，13)套设于一个螺杆14上，并且在转动该螺杆14时，两个螺母(12，13)沿该螺杆14相互靠近或远离。基于此种结构，使得辅助设备快捷并方便的安装于该轮毂夹持装置100；同时，极为方便的从该轮毂夹持装置100上将该辅助设备拆卸下来。
