Abstract:
1. A parking gear for a motor vehicle with a drive train comprising a drive shaft, said parking gear comprising a flange that is fixed to said drive shaft so that said flange cannot rotate relative to said drive shaft, an engagement wheel which is mounted coaxially with respect to said flange, said engagement wheel being rotatable relative to said drive shaft, said engagement wheel and said flange having webs which are engaged so that torque can be transmitted on a torque path between said engagement wheel and said flange, said webs of said engagement wheel meshing radially between said webs of said flange to form chambers which each have a U-shaped cross-section, said engagement wheel having a radially inward extending section, said flange and said radially inward extending section bounding said chambers axially, a locking element which can engage said engagement wheel to stop rotation of said engagement wheel, and a plurality of elastically deformable elements mounted in the torque path between said engagement wheel and said flange so that said elastically deformable elements can absorb residual rotational energy of the drive train when the engagement wheel is locked by the locking element, said elastically deformable elements each having a U-shaped cross-section and being received in a respective said chamber, said elastically deformable elements extending over respective said webs of one of said engagement wheel and said flange, wherein deformation of said deformation elements out of said chambers is limited by said flange and said radially inwardly extending section of said engagement wheel.
