Power take off coupler and vehicle hitch equipped therewith
View Patent ↗The present invention relates to a Power Take Off (PTO) coupler and a hitch equipped with such a PTO coupler. The PTO coupler comprises a power transmission coupler; and a securing mechanism. The securing mechanism is adapted for fixedly securing an extremity of the power transmission coupler to the hitch. The securing mechanism comprises a position adjustment mechanism for allowing planar movement of the power transmission coupler within the securing mechanism. The securing mechanism may further comprise a compression adjustment mechanism for adjusting pressure received by the power transmission coupler.
1. A Power Take Off (PTO) coupler comprising:
a power transmission coupler, the power transmission coupler having a first extremity adapted to be affixed to a vehicle shaft, and a second extremity adapted to engage a power mechanism of an implement; and
a securing mechanism for fixedly securing the second extremity of the power transmission coupler to a hitch, the securing mechanism comprising a position adjustment mechanism and a slot defining a perimeter of an aperture, the position adjustment mechanism being installed in the slot and allowing planar movement of the power transmission coupler within the securing mechanism;
characterized in that the second extremity is provided with a tapered male connection and the power mechanism is provided with a complementary tapered female connection adapted to receive the male connection.
2. The PTO coupler of claim 1 , wherein the position adjustment mechanism has a perimeter defining a shape similar and smaller to the aperture.
3. The PTO coupler of claim 2 , wherein the position adjustment mechanism is a plate surrounding the power transmission coupler.
4. The PTO coupler of claim 1 , wherein the position adjustment mechanism further comprises a compression adjustment mechanism for adjusting pressure and axial position received by the power transmission coupler.
5. The PTO coupler of claim 1 , wherein the PTO is configured such that teeth of the second extremity and teeth of the power mechanism do not get into contact with complementary bases, when the tapered male connection is in contact with the tapered female connection.
6. A vehicle hitch comprising:
a frame adapted to connect with a corresponding hitch of an implement;
a power transmission coupler, the power transmission coupler having a first extremity adapted to be affixed to a vehicle shaft, and a second extremity adapted to engage a power mechanism of the implement; and
a securing mechanism for fixedly securing the second extremity of the power transmission coupler to the frame, the securing mechanism comprising a position adjustment mechanism and a slot defining a perimeter of an aperture, the position adjustment mechanism being installed in the slot and allowing planar movement of the power transmission coupler within the securing mechanism;
characterized in that the second extremity is provided with a tapered male connection and the power mechanism is provided with a tapered female connection adapted to receive the male connection.
7. The vehicle hitch of claim 6 , wherein the position adjustment mechanism has a perimeter defining a shape similar and smaller to the aperture.
8. The vehicle hitch of claim 7 , wherein the position adjustment mechanism is a plate surrounding a section of the power transmission coupler proximate to the second extremity.
9. The vehicle hitch of claim 6 , wherein the position adjustment mechanism further comprises a compression adjustment mechanism for adjusting pressure and axial position of the power transmission coupler.
10. The vehicle hitch of claim 6 , wherein the PTO is configured such that teeth of the second extremity and teeth of the power mechanism do not get into contact with complementary bases, when the tapered male connection is in contact with the tapered female connection.
