1 所示,输入轴1与双向凸轮6用螺栓8固定连接,同时输入轴1起油封座和 承座的作用,在 面动态连接有油封2和第一轴承4,双向凸轮6与输出轴套 1 4 之间通过骨架5中的滚 9 与双向凸轮6的相对位移形成双向可选择的离合连接,双向凸轮6同时兼着轴承座,在上面动态连接有轴承1 1 ,用外卡簧 1 0 对第二轴承 1 1 进行轴向固定,滚柱9与复位弹片17固定装在骨架5中,制动盘12与骨架5固定连接,制动盘 1 2 受电磁控制器13控制。 The embodiment of the utility model provides an electromagnetic two-way selectable roller type overrunning clutch. As shown in FIG. 1 , the input shaft 1 and the two-way cam 6 are fixedly connected with bolts 8, and at the same time, the input shaft 1 functions as an oil seal seat and a bearing seat. An oil seal 2 and a first bearing 4 are dynamically connected on the top , and a bidirectional selectable clutch connection is formed between the bidirectional cam 6 and the output shaft sleeve 14 through the relative displacement of the roller 9 in the skeleton 5 and the bidirectional cam 6 in both directions. The cam 6 also serves as a bearing seat, and a bearing 1 1 is dynamically connected to the upper side. The second bearing 11 is axially fixed with an outer spring 10 , and the roller 9 and the reset spring 17 are fixedly installed in the skeleton 5 to brake. The disc 12 is fixedly connected to the frame 5, and the brake disc 12 is controlled by an electromagnetic controller 13.
作状态时,电磁控制器 1 3 通电,对制动盘12产生吸 力,形成旋转力矩,骨架5在制动盘12作用下,将骨架5 的滚柱9定位在双向凸轮6的自锁点,使双向凸轮6与输出轴套14锁紧,动力通过输入轴1 传输至双向凸轮6,由双向凸轮带动输出轴套1 4 、输出轴16同步旋转,当输出轴16转速高于输入轴1转速,滚柱9在复位弹片17作用下, 到模中,离合器脱开,实现超越。 As shown in Figures 1 and 3, the working process of the present utility model: when the clutch is in the working state, the electromagnetic controller 13 is energized to generate an attraction force to the brake disc 12 to form a rotational torque, and the skeleton 5 is on the brake disc. Under the action of 12, the roller 9 in the skeleton 5 is positioned at the self-locking point of the bidirectional cam 6, the bidirectional cam 6 and the output shaft sleeve 14 are locked, and the power is transmitted to the bidirectional cam 6 through the input shaft 1, and the bidirectional cam drives the output The shaft sleeve 14 and the output shaft 16 rotate synchronously. When the speed of the output shaft 16 is higher than the speed of the input shaft 1, the roller 9 returns to the mold under the action of the reset spring 17 and the clutch is disengaged to achieve overtaking.
9 位于双向凸轮6内曲面几何最高点,这时,输入 1 与输出轴16处于脱开状态,可以自由的正、反转动。 As shown in Figures 1 and 2, when the clutch is in a non-operating state, the electromagnetic controller 13 is powered off. Under the action of the reset spring 9, the roller 9 in the skeleton 5 is located at the highest geometric point of the curved surface in the bidirectional cam 6. At this time, The input shaft 1 and the output shaft 16 are in a disengaged state and can be rotated forward and backward freely.
16 作输入转轴,连接盘作动力输出端,中间连接滚柱9,滚 9 装在骨架5中,骨架5与制动盘12连接受其控制。 The utility model can also be connected in the reverse direction. The output shaft 16 is used as an input shaft, and the connection disk is used as a power output end. The roller 9 is connected in the middle, and the roller 9 is installed in the skeleton 5. The connection between the skeleton 5 and the brake disc 12 is controlled by it. .
