PROBLEM TO BE SOLVED: To achieve a steering device with a simple structure having a function of changing driving modes from a normal driving mode to a special driving mode.SOLUTION: A steering device 1 includes: a knuckle 3 provided at a chassis through a suspension unit 2; a first king pin axis 4 for rotating the knuckle 3 with respect to the suspension unit 2, in a steering direction; a second king pin axis 5 for rotating a wheel W with respect to the knuckle 3, in a direction corresponding to a driving mode of a vehicle C; first drive means 7 for steering the wheel W around the first king pin axis 4; and second drive means (an in-wheel motor) M for steering the wheel W around the second king pin axis 5. The first king pin axis 4 is engaged in the normal steering, while the second king pin axis 5 is engaged in the changeover of driving modes.SELECTED DRAWING: Figure 1
【課題】通常走行モードから特殊走行モードへの切り替え機能を有するステアリング装置を簡便な構成で実現すること。【解決手段】懸架装置2を介してシャーシに設けられたナックル3と、懸架装置2に対し、ナックル3を転舵方向に回動させる第一のキングピン軸4と、ナックル3に対し、車輪Wを車両Cの走行モードに対応する方向に回動させる第二のキングピン軸5と、第一のキングピン軸4周りに車輪Wを転舵させる第一の駆動手段7と、第二のキングピン軸5周りに車輪Wを転舵させる第二の駆動手段(インホイールモータ)Mと、を備えるステアリング装置1を構成し、第一のキングピン軸4を通常の転舵に関与させる一方で、第二のキングピン軸5を走行モードの切り替えに関与させる。【選択図】図1
