具有能切换的离合器的机动车真空泵
摘要：
本发明涉及一种机械式的机动车真空泵(10)，其具有泵转子(12)、能通过内燃机机械式地驱动的连接元件(14)、能切换的形状配合式离合器装置(30)，其用于在锁定状态中使连接元件(14)与泵转子(12)抗扭地锁定和用于在解锁状态中使连接元件(14)与泵转子(12)脱离。离合器装置(30)具有：与泵转子(12)或者连接元件(14)抗扭地连接的锁定保持件(32)，锁定保持件(32)具有至少一个径向的锁定导引装置(34)和能在锁定导引装置(34)中移动的锁定体(36)，离合器装置(30)还具有与锁定保持件(32)配置的、能轴向移动的具有向轴线倾斜的导引面(52)的导引体(50)，通过导引面(52)迫使锁定体(36)径向地到达锁定位置中，离合器装置(30)还具有与连接元件(14)或者泵转子(12)抗扭地连接的具有至少一个转动的定位凹陷(42)的定位体(40)，锁定体(36)在其锁定位置中嵌接到定位凹陷(42)中。
摘要（英）：

A motor vehicle vacuum pump includes a pump rotor, a coupling element, and a clutch arrangement. The clutch arrangement locks or releases the coupling element to/from the pump rotor so that the coupling element rotates together with or is released from the pump rotor. The clutch arrangement comprises a bolt holder connected to the pump rotor or to the coupling element to rotate therewith, an axially displaceable guide body, and a catch body connected to the coupling element or to the pump rotor to rotate therewith. The bolt holder comprises a bolt guide and a bolt body displaceable therein. The guide body is assigned to the bolt holder and comprises a guiding surface inclined with respect to an axial plane. The bolt body is forced radially into a locking position via the guiding surface. The catch body has a catch depression wherewith the bolt body engages in the locking position.
