用于变速器的形锁合切换元件的液压操纵装置
摘要：
本发明涉及一种用于变速器的形锁合切换元件(2)的液压操纵装置(1)，其包括缸体(3)，活塞(4)在所述缸体中在第一端部位置和第二端部位置之间可移动地设置。活塞(4)构造为分级活塞并且与缸体(3)限定另一压力室(9)，所述另一压力室与第一压力室(5)和/或与第二压力室(8)通过至少一个液压管路(10；20)至少在活塞的定义的调节行程上相连接。所述另一压力室的容积在活塞朝向第一端部位置调节运动期间减小，而在活塞朝向第二端部位置调节运动期间增大。在所述另一压力室(9)与第一压力室(6)和/或第二压力室(8)之间的连接被缸体阻断的阻断程度从活塞在到达第一端部位置之前的定义的调节行程起直至第一端部位置增加。
摘要（英）：

The invention relates to a hydraulic actuating device (1) for a shape-locking shifting element (2) of a transmission. The hydraulic actuating device is provided with a cylinder (3), in which a piston (4) is arranged in a manner displaceable between a first end position and a second end position. The piston (4) is a stepped piston and, with the cylinder (3), bounds an additional pressure chamber (9), which is connected to a first pressure chamber (5) and/or a second pressure chamber (8) through at least one hydraulic line (10; 20). The volume of the additional pressure chamber decreases during an actuating movement of the piston in the direction of the first end position and increases during an actuating movement of the piston in the direction of the second end position. The degree of locking of the connection between the additional pressure chamber (9) and the first pressure chamber (6) and/or the second pressure chamber (8) increases through the cylinder from a defined actuating path of the piston prior to reaching the first end position up to the first end position.
