  • Patent number: 8616576
    Abstract: A hitch apparatus has a tongue member with drawpin hole. Upper and lower clevis straps are pivotally attached to a corresponding top and bottom sides of the tongue member about vertical pivot axes, such that the clevis straps can pivot from an operating position, where the upper clevis strap is above the drawpin hole and the lower clevis strap is below the drawpin hole, to an idle position where the clevis straps extend laterally from the tongue member. When the clevis straps are in the operating position, upper and lower clevis holes in the corresponding clevis straps are vertically aligned with the drawpin hole in the tongue member, and a recess is formed between one of the upper and lower clevis straps and the tongue member. A drawpin retainer prevents upward movement of a drawpin out of engagement with the clevis and drawpin holes.

  • Patent number: 8579072
    Abstract: Electric power steering system has steering mechanism; input and output shaft side rotation angle sensors detecting rotation angles of input and output shafts; operation circuit calculating command current for an electric motor; rotation direction judging circuit judging whether rotation directions of the input and output shafts are identical; advanced-phase judging circuit judging which phase of input and output shaft side rotation angle signals (S1, S2) is advanced; normal/reverse input judging circuit judging that (i) when both rotation directions are identical and S1 is advanced, input is normal input and (ii) when both rotation directions are identical and S2 is advanced, input is reverse input; and command current correcting circuit. The command current correcting circuit corrects the command current so that when the normal input is judged, torque in the same direction as input shaft rotation direction generated by the electric motor is greater than a case of reverse input judgment.
