The present disclosure provides "variable pitch stator and dual hydraulic channel control". A vehicle driveline component includes a torque converter including an actuator and a clutch. The actuator includes an actuator piston that is slidable within an actuator chamber and divides the actuator chamber into a slack chamber and a tighten chamber. The actuator piston moves the stator blades between a plurality of pitch positions. A clutch selectively couples the turbine to the impeller. The clutch includes a spring and a clutch piston. The clutch piston at least partially defines an application chamber and a release chamber. The application chamber is in fluid communication with the tightening chamber via the hydrodynamic chamber. The release chamber is in fluid communication with the relaxation chamber. The clutch piston is movable between an engaged position in which relative rotation between the housing and the turbine is suppressed and a disengaged position in which relative rotation is permitted. A clutch spring is supported by the turbine hub and biases the clutch piston toward the disengaged position.
本公开提供了“可变节距定子和双液压通道控制”。一种车辆传动系部件包括变矩器,变矩器包括致动器和离合器。致动器包括致动器活塞,致动器活塞能够在致动器腔室内滑动并且将致动器腔室分成松弛腔室和收紧腔室。致动器活塞使定子叶片在多个节距位置之间移动。离合器将涡轮选择性地联接到泵轮。离合器包括弹簧和离合器活塞。离合器活塞至少部分地限定施加腔室和释放腔室。施加腔室经由流体动力腔室而与收紧腔室处于流体连通。释放腔室与松弛腔室处于流体连通。离合器活塞能够在抑制壳体和涡轮之间的相对旋转的接合位置与允许相对旋转的脱离位置之间移动。离合器弹簧由涡轮轮毂支撑并且将离合器活塞朝向脱离位置偏置。
