    • A rotational control apparatus (A) having a rotatable input (26 or 180) and output (26 or 180) with respective interface discs (106, 180). Three sets of two diametrically opposed pistons (64 and 66, 68 and 70, 72 and 74) are controllable to rotatably relate the interface discs (106, 180). The piston sets (64 and 66, 68 and 70, 72 and 74) include piston heads (76) with dissimilar diameters such that each of the sets of pistons (64 and 66, 68 and 70, 72 and 74) may apply a dissimilar torque for a given amount of air pressure. Each of the piston sets (64 and 66, 68 and 70, 72 and 74) may be actuated independently or in combination with each of the other sets of pistons (64 and 66, 68 and 70, 72 and 74) such that the interface discs (106, 180) may be rotatably related to each other with varying degrees of torque. The rotational control apparatus (A) also includes a unique interface disc (106) with a frustoconical annular projection (136) for drawing relatively hot air away from the hub (26) near the interface disc (106) and out of the apparatus (A). The rotational control apparatus (A) further includes a unique set of axially extending channels (38, 60, 111) for the conveyance of air for cooling the interface discs (106, 180) from a location remote from the interface discs (106, 180). Blades (152) on interface disc (106) draw relatively cool air through the channels (38, 60, 111) to the hub (26) near the interface disc (106).
    • 旋转控制装置(A)具有可旋转的输入(26或180)以及具有相应接口盘(106,180)的输出(26或180)。 三组两个直径相对的活塞(64和66,68和70,72和74)是可控制的,以可旋转地联接接口盘(106,180)。 活塞组件(64和66,68和70,72和74)包括具有不同直径的活塞头(76),使得每组活塞(64和66,68和70,72和74)可以施加不同的 给定空气压力的扭矩。 每个活塞组(64和66,68和70,72和74)可以独立地或与其它活塞组(64和66,68和70,72和74)中的每一个组合地致动,使得界面 盘(106,180)可以以不同的扭矩相互可旋转地相关联。 旋转控制装置(A)还包括具有截头圆锥形环形突起(136)的独特的界面盘(106),用于将接近盘(106)附近的轮毂(26)的相对热空气从设备(A) )。 旋转控制装置(A)还包括一组独特的轴向延伸的通道(38,60,111),用于输送空气以从远离接口盘(106,180)的位置冷却接口盘(106,180) )。 接口盘(106)上的叶片(152)将较冷的空气通过通道(38,60,111)吸附到接口盘(106)附近的轮毂(26)。
