请参阅图1和图2，图1为本发明实施例提供的螺母式电子机械式制动组件的剖面结构示意图；图2为本发明实施例提供的螺母式电子机械式制动组件的部分结构示意图。
本发明实施例公开了一种螺母式电子机械式制动组件，该螺母式电子机械式制动组件包括：钳体1、滚珠丝杠结构、执行器3、内摩擦片4和外摩擦片5。
钳体1与执行器3固定连接，例如，可以通过螺纹紧固件固定连接。
钳体1开设有一贯穿的缸孔11。
滚珠丝杠结构设置于缸孔11中。
滚珠丝杠结构包括螺杆21、螺母22和钢珠23。
螺杆21的一端伸出缸孔11并与执行器3驱动连接。
可选地，在本实施例中，螺杆21的端部采用Trox接口形式的花键212与执行器3驱动连接。执行器3输出扭矩直接带动螺杆21转动。螺杆21采用的Trox花键212相比于传统EPB12齿花键，传动效率提升46％，能有效减小驱动器电机的驱动电流。
进一步地，缸孔11设置为阶梯孔，包括第一孔111和第二孔112，第二孔112的直径大于第一孔111的直径，第二孔112邻近内摩擦片4设置，螺杆21设置有一推力平台211，推力平台211与阶梯面113相适配。
进一步地，推力平台211与阶梯面113之间夹设有推力轴承61和平垫圈62，其中推力轴承61靠近推力平台211设置，平垫圈62远离推力平台211设置。
进一步地，螺杆21位于第一孔111内的一段套设有滚针轴承63。滚针轴承63提高了螺杆21的使用寿命以及传动效率，且滚针轴承63限制了螺杆21的径向运动，当然，也可以使用滑动轴承或者衬套。
螺杆21的另一端伸入螺母22内。
具体地，在本实施例中，螺母22为一端开口的筒形件，开口端朝向螺杆21，螺杆21伸入螺母22内。
螺母22背离螺杆21的一端与内摩擦片4固定连接。
钢珠23夹设在螺母22与螺杆21之间。
外摩擦片5固定装设在钳体1上，且外摩擦片5与内摩擦片4相对设置。
具体地，内摩擦片4与螺母22固定连接，跟随螺母22一起直线往复运动。
外摩擦片5与内摩擦片4相对设置，固定设置在钳体1远离螺母22的一侧，与内摩擦片4一起用于夹紧设置在内摩擦片4和外摩擦片5之间的制动盘(图未示)。
当执行器3驱动螺杆21向正方向转动，螺杆21给到螺母22一个向靠近外摩擦片5方向的(图1中向右)作用力，推动螺母直线运动，进而带动内摩擦片4向靠近外摩擦片5的方向直线运动，而螺杆21会受到螺母22的反作用力并对钳体1的阶梯面113产生推力，推动钳体1向远离外摩擦片5的方向直线 运动，钳体1带动外摩擦片5向靠近内摩擦片4的方向直线运动，则外摩擦片5与内摩擦片4相互靠近一起夹紧制动盘，实现刹车制动模式，当执行器3驱动螺杆21向反方向转动，螺杆21带动螺母22直线运动，进而带动内摩擦片4向远离外摩擦片5的方向直线运动，以与外摩擦片5一起松开制动盘，实现另一制动模式，其中，正方向与反方向为两个相反的方向即可，例如正方向可以为顺时针方向，反方向可以为逆时针方向。
进一步地，螺母22靠近内摩擦片4的一端与缸孔11内壁之间设置有密封圈64。优选地，螺母22与缸孔11内壁采用间隙配合，密封圈64与螺母22外径采用过盈配合，密封圈64与缸孔11内壁采用过盈配合。这样设置不仅起到缸孔11内部密封防尘的作用，同时能储存润滑油，稳定滚珠丝杠结构的运动。在本实施例中，螺母22与密封圈64是过盈配合，所以两者必定存在摩擦力。因此在螺杆21伸出钳体1的一段，如图2所示，设计了一个限位卡簧7，用于防止在螺杆21反转、螺母22退回时花键212脱离执行器3，造成动力损失，制动器无法解除制动的失效情况。可选地，限位卡簧7可以采用弹性好、强度高的锰钢材质。
优选地，螺母22靠近内摩擦片4的一端还设置有压紧弹簧8。压紧弹簧8嵌设在螺母22与钳体1的缸孔11内壁之间。
本实施例中的螺母式电子机械式制动组件，通过螺杆21、螺母22和钢珠23相匹配，使得螺母式电子机械式制动组件整体结构简单紧凑，体积小。
以上实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特 征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
