ABSTRACT:
A biconical torque body construction for traction drive transmissions in which a pair of hollow cone members, telescopically joined at the base or large diameter ends thereof for relative axial movement, are keyed or otherwise prevented for rotation relative to each other. A torque member is supported centrally within the hollow cone members with freedom of movement axially and rotatably relative to both cone members and constitutes the sole connection of the body for torque transmission to a transmission unit output load. The torque member carries one side of a ramp system cooperable with at least one of the cone members so that torque transmission between the cone members and the torque member will develop an axial force acting to separate the two cone members on the axis of the biconical body and proportional to the output torque load imposed on the body. The torque member is compression-resistant at least for that portion of its length between the ramp system and one of the cone members.
