一种气隙宽度自调整的电磁制动装置
摘要：
本发明公开一种车辆制动器中的气隙宽度自调整的电磁制动装置，定子铁芯一端是磁轭端部、另一端固定连接于定子支架，定子支架还固定连接热膨胀连接件一端，热膨胀连接件另一端固接绝缘层一端，热膨胀连接件与定子铁芯均位于定子支架同一侧并且相互平行，绝缘层另一端固接在法兰盘上，定子铁芯和定子支架材料的线膨胀系数相同，且均比热膨胀连接件材料的线膨胀系数小；在沿定子铁芯的轴向上，所述热膨胀连接件的长度小于所述定子铁芯长度和所述定子支架长度之和；当电磁制动装置温度升高时，热膨胀连接件的线膨胀量抵消了定子铁芯和定子支架的线膨胀量，保持气隙宽度基本不变。
摘要（英）：

The invention discloses an air gap width self-adjusting type electromagnetic braking device in a vehicle brake. One end of a stator core is a magnet yoke end, and the other end of the stator core is fixedly connected to a stator carrier. The stator carrier is further fixedly connected with one end of a thermal expansion connector, and the other end of the thermal expansion connector is fixedly connected with one end of an insulating layer. The thermal expansion connector and the stator core are located on the same side of the stator carrier and parallel to each other, and the other end of the insulating layer is fixedly connected to a flange plate. The linear expansion coefficient of the stator core material and the linear expansion coefficient of the stator carrier material are identical and both smaller than that of the thermal expansion connector material. In the axial direction of the stator core, the length of the thermal expansion connector is smaller than the sum of the length of the stator core and the length of the stator carrier. When the temperature of the electromagnetic braking device rises, the linear expansion amount of the thermal expansion connector counteracts that of the stator core and stator carrier, so that the air gap width is kept unchanged basically.
