Gear box i.e. power-split gear box, for mutual transferring force between traction wheel and traction hollow ring gears, has guiding element provided at position of contact to traction unit and rotatably arranged around central axle of box

摘要

The box (100) has a traction unit (130) provided between a traction wheel (110) and traction hollow ring gears (120). A part of a traction element (135) transmitting a force between the traction wheel and ring gears engages with a traction wheel-positive closure (115) and a traction hollow wheel positive locking (125). A guiding element (150) is rotated around a central axle (127) and provided at a position of contact to a traction unit (130). The guide element is centrally and rotatably arranged around the central axle of the box. Independent claims are also included for the following: (1) a method for manufacturing a gear box (2) a method for mutual transferring a force between a traction wheel and traction hollow ring gears.
