A steering column assembly includes a mounting bracket having a first arm and a second arm, a steering column and a locking device which is configured to be in a locking state or an unlocking state to selectively allow a tilt motion of the supporting housing and the steering column by applying or removing clamping force to or from the first arm and the second arm. The locking device includes a tilting bolt which is connected to the lever to rotate together with the lever and passes through the first arm and the second arm to be able to rotate between the locking state and the unlocking state and a first locking unit and a second locking unit which respectively operate in response to rotation of the tilting bolt and selectively apply clamping force to the first and the second arms.

Steering column assembly

A collapsible steering column assembly includes: a mounting bracket having a pair of arms and is configured to be fixed to a vehicle body; a supporting housing which is disposed between the pair of arms to be tiltable about the mounting bracket; a steering column which passes through the supporting housing so as to be able to undergo a tilt motion together with the supporting housing; and a locking device which is configured to be in a locking state or an unlocking state to selectively allow a telescopic motion and a tilt motion of the steering column by selectively applying clamping force to the pair of arms. The steering column comprises an outer jacket, an inner jacket which is slidably inserted into the outer jacket and a tolerance ring which is interposed between the outer jacket and the inner jacket, and the tolerance ring is configured so as to make the inner jacket and the outer jacket move together to realize a telescopic motion in the unlocking state of the locking device and so as to allow the inner jacket to move into the outer jacket by impact in the locking state of the locking device. The tolerance ring is configured to move relative to the outer jacket in a longitudinal direction while the inner jacket collapses into the outer jacket.

Collapsible steering column assembly

A constant-velocity joint assembly includes: a first and a second shaft portions respectively provided with a protrusion; a double yoke portion in which a guide hole is formed along an axis direction, the first and the second shaft portions being respectively rotatably connected to both sides of the guide hole with an axis of an upper/lower direction; and a guide portion which is disposed to the guide hole to guide the protrusion and rotates along an inner circumference of the guide hole during rotation of the shaft portions, wherein the first and the second shaft portions respectively comprises: a spider body, a left and a right leg, and an upper and a lower legs; a shaft provided with the protrusion; and a yoke block comprising a block body, and a left and a right connecting member.
