Abstract
The invention relates to a transmission assembly (34), for imparting a phase difference between an outer wheel and an inner wheel of a spline VVT. The assembly comprises a tubular meshing member (36) having an inner surface (38) and an outer surface (40), wherein at least a portion of the inner surface is provided with a first spline (42) and at least a portion of the outer surface is provided with a second spline (44). 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 (46) and an actuation member (48). 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.
