Abstract
A vehicle steering apparatus and a vehicle include a ball nut coupled to a rack bar by means of a ball and configured to linearly move or slide the rack bar in an axial direction by rotation of the ball nut, first and second nut pulleys provided on an outer peripheral surface of the ball nut, a first motor pulley provided on a first motor and operably connected to the first nut pulley through a first belt, a second motor pulley provided on a second motor and operably connected to the second nut pulley through a second belt, and a rotation prevention member arranged to support an outer peripheral surface of the rack bar, supported by an inner peripheral surface of a rack housing and configured to prevent rotation of the rack bar.
Claims20
A steering apparatus comprising:
- a rotatable nut operably coupled to a rack bar and configured to linearly move the rack bar by rotation of the rotatable nut;
- first and second nut pulleys provided on an outer surface of the rotatable nut;
- a first motor pulley of a first motor operably connected to the first nut pulley through a first belt;
- a second motor pulley of a second motor operably connected to the second nut pulley through a second belt;
- and
- a rotation prevention member supporting an outer surface of the rack bar, supported by an inner surface of a rack housing, and configured to prevent rotation of the rack bar.
