摘要： The present invention relates to a compact clutch 30. The clutch comprises a driven shaft 24 on which the following are mounted: a gear wheel 32; a driving bush 34; a driven bush 36; a coil spring 38; a first collar 40 with cam surfaces 404; and a second collar 42 with cam surfaces 424. The gear wheel and the bushes are arranged axially next to each other; the gear wheel and the driving bush are constrained together in the circumferential direction; the spring surrounds externally the bushes; the first collar surrounds externally the spring; and the second collar surrounds externally the first collar. The second collar may be displaced in an axial direction between a rest position and a working position. When the second collar is displaced into the working position: cam surfaces of the collars cause a tightening of the spring around the bushes; the tightening of the spring constrains the bushes together. The clutch according to the invention is characterized in that the gear wheel and the bushes are constrained to the driven shaft in the axial direction by means of two stop rings 326, 366; in that the driven bush is constrained to the driven shaft in the circumferential direction by means of at least one tongue 362; and in that the tongue ensures engagement between the driven bush and the driven shaft in the circumferential direction, while in the axial direction the driven bush may slide with respect to the driven shaft. The invention also relates to a drive 20 comprising the compact clutch 30 according to the invention.
摘要翻译：本发明涉及一种紧凑型离合器30.该离合器包括从动轴24，在该从动轴上安装以下部件：齿轮32; 驱动衬套34; 从动套筒36; 螺旋弹簧38; 具有凸轮表面404的第一套环40; 以及具有凸轮表面424的第二套环42.齿轮和套筒轴向并排布置; 齿轮和驱动衬套在圆周方向上被约束在一起; 弹簧在外部包围灌木丛; 第一套环在外部包围弹簧; 并且第二套环在外部包围第一套环。第二套环可以在静止位置和工作位置之间沿轴向移动。当第二套环移位到工作位置时：套环的凸轮表面引起套管周围弹簧的收紧; 弹簧的收紧将衬套限制在一起。根据本发明的离合器的特征在于，齿轮和衬套借助于两个止动环326,366被限制在从动轴上，其中，从动轴套通过至少一个舌片362沿周向限制在从动轴上; 并且舌片确保从动轴套与从动轴之间在圆周方向上的啮合，而在轴向方向上，从动轴套可相对于从动轴滑动。本发明还涉及包括根据本发明的紧凑型离合器30的驱动器20。
