摘要： A clutch provides two pairs of friction faces between rotatable input and output hubs. One of said hubs provides a coaxial cylindrical surface for support of the other hub and a neutral hub between a pair of radially outwardly extending shoulders providing its friction faces. The other hub, and the neutral hub are rotatably supported on the cylindrical surface between the shoulders with spring means associated with one of the friction faces urging the hubs together and the friction faces into contact with one another. A ring which is wedge shaped in radial cross sections and capable of being pressed inwardly lies preferably in a wedge shaped groove between said other hub and neutral hub. A helical spring surrounds the outer face of the ring and when wrapped down urges the ring inwardly to urge the block and hub apart and their respective clutch faces into the opposed clutch faces of the other hubs with sufficient force to permit transmission of torque.

摘要： A helical clutch spring is attached one end to the output hub and at its other end to a collar and lies opposite a cylindrical clutch surface of an input hub. The clutch spring tends to be normally out of engagement with the clutch surface. However, by virtue of resilient means urging a surface on the collar into an opposed surface on the input hub, the rotation imparted to the collar causes the spring to engage the input hub and drive the output hub through the spring. Actuator means may be selectively caused to act upon the collar to draw it in opposition to the resilient means away from the input hub and allow the spring to return to its normal position and the clutch to disengage.

摘要翻译： 螺旋式离合器弹簧的一端连接到输出轮毂上，另一端连接到轴环上并与输入轮毂的圆柱形离合器表面相对置。 离合器弹簧通常与离合器表面通常脱离接合。 然而，由于将套环上的表面推动到输入轮毂上的相对表面的弹性装置，赋予轴环的旋转使得弹簧与输入轮毂接合并通过弹簧驱动输出轮毂。 可以选择性地使致动器装置作用在套环上，以使其与弹性装置相对地离开输入轮毂，并允许弹簧返回其正常位置并且离合器脱离。
