外壳 20与本体部 110之间设置有可相互弹性地卡入或脱离的卡扣 槽和卡扣部, 本实施例中, 外壳 20上设置有一对卡扣部 202, 本体部 110上开设有一对卡扣槽 111,将外壳 20的卡扣部 202压入本体部 110 的卡扣槽 111 内, 即可将感应件 2安装在固定件上。 同理, 在其他实 施方式中, 可以在本体部 110上设置卡扣部, 在外壳 20上开设卡扣槽 111, 也可以将感应件 2安装在固定件上。 外壳 20与本体部 110之一 上还设置有弹性部, 卡扣部设置在该弹性部上, 本实施方式中, 弹性 部是弹性臂 200, 具有一定弹性, 卡扣部 202设置在弹性臂 200上。 按压弹性臂 200, 使卡扣部 202脱离卡扣槽 111, 即可将感应件 2从固 定件上拆除下来。 可选地, 弹性部可以是其它形式, 只要其可以使卡 扣部 202卡入或脱离卡扣槽 111 即可, 例如弹性部可以是弹簧, 卡扣 部 202设置在弹簧上。 可选地, 外壳 20与本体部 110之一上还可以设 置按压部, 在本实施方式中, 弹性部与按压部均设置在外壳 20, 例如, 按压部 203设置在本实施方式的弹性臂 200上, 用以按压弹性臂 200, 使卡扣部 202卡入或脱离卡扣槽 111。在其他实施方式中, 弹性部与卡 扣部设置在外壳 20与本体部 110之一上, 按压部设置在外壳 20与本 体部 110另外之一上, 直接对卡扣部 202施加压力。
可选地,外壳 20与本体部 110之间还可以设置安装槽和安装凸肋, 本实施例中, 外壳 20上设置有安装凸肋 204, 本体部 110上开设有安 装槽 112,将外壳 20的安装凸肋 204压入本体部 110的安装槽 112内, 即可将感应件 2安装在固定件上, 反向操作, 即可将感应件 2从固定 件上拆除下来。 同理, 在其他实施方式中, 可以将安装凸肋设置在本 体部 110上, 安装槽开设在外壳 20上, 从而将感应件 2安装在固定件 上。
卡扣槽和卡扣部设置在外壳 20与本体部 1 10之间的一侧, 所述安 装槽和安装凸肋设置在外壳 20与本体部 110之间的一侧或另一侧。例 如, 本实施方式中, 卡扣槽 1 1 1设置在本体部 110相对两侧, 安装槽 1 12也对应地设置在本体部 1 10的该相对两侧;卡扣部 202设置在外壳 20相对两侧, 安装凸肋 204也对应地设置在外壳 20的该相对两侧。 在其他实施方式中, 卡扣槽 1 1 1 设置在本体部 1 10相对两侧, 而安装 槽 112设置在本体部 110的另一相对两侧; 卡扣部 202设置在外壳 20 相对两侧, 安装凸肋 204设置在外壳 20的另一相对两侧。
可选地, 外壳 20与本体部 110之间的卡扣槽、 卡扣部的数量可以 一个或多个, 外壳 20与本体部 110之间的安装槽、 安装凸肋可以是零 个、 一个或多个。 例如, 在一实施方式中, 外壳 20与本体部 1 10的一 侧设置一个卡扣槽和一个卡扣部, 外壳 20与本体部 110的同侧和 /或 其他侧设置一个或多个安装槽以及一个或多个安装凸肋, 也可以将感 应件 2稳固地安装在固定件上。 又例如, 在其他实施方式中, 外壳 20 与本体部 1 10之间可以设置两个或以上的卡扣槽和两个或以上的卡扣 部, 外壳 20与本体部 110之间不设置或设置一个或多个装槽以及一个 或多个安装凸肋。
该磁场产生单元包括固定于轮毂凸台 71 的环绕部 3 1、 由环绕部 3 1 向轮毂凸台 71轴心延伸的承载部 32 以及磁场产生件 (未图示)。 在本实施方式中, 磁场产生件设置在承载部 32, 即磁场产生单元的磁 场产生件大致垂直于轮毂 70的中心轴设置。 组装后, 该磁场产生件被 本体部 1 10套覆, 并与感应件 2的感应电路板 21相对, 能相对于该感 应电路板 21转动而被感应件 22侦测。
该磁场产生单元的环绕部 31沿轮毂凸台 71 的轴向延伸, 且环绕 部 31被构造成适合与轮毂凸台 71紧密配合,使环绕部 3 1不能相对于 轮毂凸台 71 作径向转动或轴向移动, 承载有磁场产生件的承载部 32 沿轮毂凸台 71 的径向延伸并紧贴轮毂凸台 71 的端面, 对应地, 感应 件 2的延伸方向大致垂直于轮毂 70的中心轴,使感应件 2靠近并平行 于磁场产生件。 在其他实施方式中, 磁场产生件设置在环绕部 31上, 沿轮毂凸台 71的轴向延伸, 对应地, 感应件 2的延伸方向大致平行于 轮毂 70的中心轴。
组装时, 轴承 72同心套设在轮毂凸台 71与螺杆 73之间, 将磁场 产生单元以紧密配合方式固定在轮毂凸台 71上,套管 12的结合端 121 同心插入本体部 110的结合管 113, 将套管 12通过过盈配合的方式紧 密套在螺杆 73上; 减震器 75固定在螺杆 73上, 使减震器 75抵靠套 管 12的凸台端 122末端,使套管 12的两端分别抵持轴承 72和减震器 75 , 即轴承 72和减震器 75将套管 12挤压固定于其间; 利用螺母 74 固定, 使轮速传感装置的感应单元无法转动或移动, 即感应电路板 21 无法转动或移动, 而轮毂 70能透过轴承 72转动并同时带动该磁场产 生单元转动, 即带动磁场产生单元的磁场产生件转动。 将感应电路板 21固定在收容槽 201内形成感应件 2,将外壳 20的安装凸肋 202压入 本体部 110的安装槽 111 内, 即可将感应件 2安装在固定件上, 使感 应电路板 21靠近并平行于磁场产生单元的磁场产生件,完成安装感应 件 2的步骤。 由于感应件 2采用模块化结构, 且感应件 2的外壳 20与 固定件上之间设置有可相互弹性地卡入或脱离的卡扣槽和卡扣部, 可 以在固定件上方便地安装或拆除, 因此, 可在上述任何步骤中安装或 拆除感应件 2。
当车辆行驶时, 该轮毂 70带动该磁场产生单元转动, 该磁场产生 件跟着旋转而产生交变的磁场, 无法转动的感应电路板 21 的感应件 22即会受到交变磁场的作用, 产生感应电路, 从而根据感应电流的变 化而得知该磁场产生件的转动速度, 计算出车辆的行驶速度。 本申请 轮速传感装置还包括传输线 6, 与感应电路板 21电性连接, 用以将轮 速传感装置的检测信号传输至车辆的电子控制单元。
当轮速传感装置发生故障时, 仅需按压弹性臂 200, 即可使卡扣 部 202脱离卡扣槽 111, 将感应件 2从固定件上拆除, 然后在固定件上 安装上正常的感应件或者正确型号的感应件即可。除了感应件 2之外, 不需要拆除和更换固定件或者其他任何元件, 从而很方便地修复发生 故障的轮速传感装置; 另外, 感应件 2 内装配不同型号得感应电路板 21即可构成不同型号的感应件, 在不改变轮速传感装置的其他元件的 前提下, 可以很方便地实现轮速传感装置的换型, 形成不同型号的轮 速传感装置, 因此通用性好。
本申请感应单元、轮速传感装置以及使用该轮速传感装置的车辆, 由于感应件采用模块化结构, 可以从固定件上方便地安装或拆除, 可 以很方便地修复故障轮速传感装置, 并且可以很方便地形成不同型号 的轮速传感装置, 因此结构简单、 方便修复故障且通用性好。
