Abstract
An interlocking device arranged to prevent at least one forbidden combination of engaged/disengaged positions of three tooth clutch groups in a vehicle transmission is provided. Each tooth clutch group is arranged to rotationally lock/unlock a shaft from a gearwheel. A shift rod is arranged to push a tooth clutch between engaged/disengaged position. The interlocking device includes movable elements where each movable element is directed towards one of the shift rods in order to lock one of the tooth clutch groups in the disengaged position, and an interlocking element arranged in the middle of the movable elements. A diameter of the interlocking element and lengths of the movable elements are adapted to allow only two of the tooth clutch groups to be engaged simultaneously.
