Abstract
The invention relates to a transmission assembly (), for imparting a phase difference between an outer wheel and an inner wheel of a spline VVT. The assembly comprises a tubular meshing member () having an inner surface () and an outer surface (), wherein at least a portion of the inner surface is provided with a first spline () and at least a portion of the outer surface is provided with a second spline (). The first spline and the second spline do not have the same pitch in the same groove direction. The transmission assembly further comprises a bearing arrangement () and an actuation member (). The bearing arrangement is arranged between the meshing member and the actuation member to allow a transfer of an axial displacement of the actuation member to the meshing member and allow a rotation of the meshing member relative to the actuation member.
