  • Lower type motor driven column apparatus
    Patent number: 8376402
    Abstract: A lower type motor-driven column apparatus includes a tilt unit having a column tube and a tilt link forming a plurality of hinge fixed points in order to tilt up/down a steering wheel by vertical motion generated with rotation due to straight motion of a tilt rod through a tilt motor, a telescopic unit implementing telescopic movement pushing or pulling the column tube by means of straight motion of a tele-rod through a tele-motor, and a shock-absorbing member absorbing and attenuating a shock stroke of the column tube, ahead of the tilt unit and the telescopic unit, in which the operation mechanism of the tilt unit and the operation mechanism of the telescopic unit are individually implemented, such that the MDPS can be easily used for middle-sized and large-sized vehicles which are difficult to use the upper type and it is possible to save fuel of the middle-sized and large-sized vehicles.
