Abstract: Improved performance of arc coil springs by stress reduction when they are bottomed out is achieved by forming the coil spring wire in a substantially trapezoidal or other shape such that when bottomed, the side surfaces of the coil abut and carry the bottoming load which is distributed over a comparatively large surface area. The angles of the sidewalls of the substantially trapezoidal cross section wire are preferably coincident with lines of radius when the spring is installed in an arc in a clutch, damper or flywheel. The radius of the outer surface of the arc coil spring wire is matched to the radius of the inner surface of the guide or housing so that the area of contact is large, thereby distributing the outwardly directed spring force over a large area, reducing the force per unit area and improving lubrication retention on the contacting surfaces.
Abstract translation: 电弧螺旋弹簧通过应力降低而提高的性能通过将螺旋弹簧丝线形成为大致梯形或其它形状来实现，使得当有底部时，线圈的侧表面邻接并承载分布在其上的底部载荷 相对较大的表面积。 当弹簧安装在离合器，阻尼器或飞轮中的弧中时，基本上梯形横截面线的侧壁的角度优选地与半径线重合。 电弧螺旋弹簧丝的外表面的半径与引导件或壳体的内表面的半径相匹配，使得接触面积大，从而将向外指向的弹簧力分布在大面积上，从而减小了力 并提高接触表面的润滑保持力。

Abstract: A transmission is disclosed having a planetary gear set with three input torque-transmitting mechanisms, such as friction clutches, to achieve torque flow through the planetary gear set to a countershaft gearing arrangement. The transmission includes an input member, an output member, a planetary gear set, an input clutch assembly having three input clutches and a countershaft gearing arrangement. The countershaft gearing arrangement is operatively connected with the planetary gear set and includes: a pair of co-planar intermeshing gears, first and second countershafts, a first intermediate shaft and a second intermediate shaft concentric with the first intermediate shaft.
