Abstract:
1. A web unit for planetary gear sets for a mounting of a planetary gears, comprising: a first web element having a first web contact region including a first web front face having a first web contact surface; a second web element being tightly connected to said first web element, said second web element having a second web contact region including a second web front face having a second web contact surface; at least one of a transmission element and a connecting element tensioning said first web element and said second web element progressing in an axial direction describing a theoretical connecting axis, each of said at least one of a transmission element and a connecting element having a plurality of regions of differing radial dimensions, said regions of differing radial dimensions including a first front face having a first contact surface and a second front face having second contact surface, said first contact surface resting in part one of directly against said first web contact surface and indirectly against said first web contact surface through a first intermediate element, said second contact surface resting in part one of directly against said second web contact surface and indirectly against said second web contact surface through a second intermediate element; at least one segment of at least one of said first web contact surface, said second web contact surface, said first contact surface, and said second contact surface being formed by at least one profile, at least one said profile being characterized in a radially external region by at least one region of greater axial extension in said axial direction, said region of greater axial extension defines a dimension of said contact surface in an unloaded state of web unit.
