    • The differential (22) includes a cross-shaft (52) operatively coupled to the differential case (26); left and right clutch actuators (90R,90L), having opposing inboard sides between which the cross-shaft is positioned; and left and right axle hubs (88L,88R) positioned on opposite sides of the cross-shaft. A left clutch pack (94L) prevents relative rotation between the left clutch actuator and the left axle hub when a left clutch engagement pressure is applied and a right clutch pack (94R) prevents relative rotation between the right clutch actuator and the right axle hub when a right clutch engagement pressure is applied. A clutch pre-load spring (100) applies pressure to both the left and right clutch packs without applying pressure to the left and right clutch actuators. The clutch pre-load spring (100) is positioned inboard of the left and right clutch packs. Contact between the cross-shaft and a ramp surface (114,116) at the inboard side of the left clutch actuator causes the left clutch engagement pressure to be applied to the left clutch pack, and contact between the cross-shaft and a ramp surface at the inboard side of the right clutch actuator causes the right clutch engagement pressure to be applied to the right clutch pack.
    • 差速器(22)包括可操作地联接到差速器壳体(26)的十字轴(52); 左,右离合器致动器(90R,90L),所述左,右离合器致动器具有相对的内侧,所述横轴位于所述内侧之间; 以及位于横轴两侧的左右轮毂(88L,88R)。 当左离合器接合压力被施加时,左离合器组件(94L)防止左离合器致动器和左轴毂之间的相对旋转,并且右离合器组件(94R)防止右离合器致动器和右轴毂之间的相对旋转 施加右离合器接合压力。 离合器预加载弹簧(100)向左和右离合器组件两者施加压力,而不向左和右离合器致动器施加压力。 离合器预加载弹簧(100)位于左侧和右侧离合器组件的内侧。 横轴与左离合器致动器内侧的斜面(114,116)之间的接触导致左离合器接合压力施加到左离合器组件,并且横轴与 右离合器致动器的内侧导致右离合器接合压力施加到右离合器组件。
