ABSTRACT:
A steering system for a vehicle including a fixed body secured to the body of the vehicle, a fixed shaft rotatably supported by the fixed bracket, a movable bracket connected for relative axial movement to the fixed bracket, a movable shaft rotatably supported by the movable bracket and connected to the shaft so as to be axially movable relative to the fixed shaft and rotatable as one unit with the fixed shaft, a driving mechanism disposed on the fixed bracket and connected to move the movable bracket and the movable shaft axially relative to both the fixed bracket and the fixed shaft, and a control mechanism for controlling the level of the frictional force acting between the fixed bracket and the movable bracket. The control mechanism normally maintains the frictional force at a level to ensure rigidity between the fixed and movable brackets, but is operable, upon actuation of the driving mechanism, to reduce the frictional force and thereby decrease resistance to relative axial movement of the fixed and movable brackets.
