Vehicle having shock absorber mounting angle variation structure
A vehicle having a shock absorber mounting angle variation structure may include a lower arm with a side rotatably disposed at a lower portion of a vehicle body, a shock absorber attenuating vibration due to vertical motion of the lower arm, wherein the shock absorber includes an upper end connected to an upper portion of the vehicle body, and a lower end coupled to an end of the lower arm, and a driving unit disposed on the lower arm and pushing or pulling the lower end of the shock absorber in a predetermined direction.
1. A vehicle having a shock absorber mounting angle variation structure, comprising:
a lower arm with a side rotatably disposed at a lower portion of a vehicle body;
a shock absorber attenuating vibration due to vertical motion of the lower arm, wherein the shock absorber includes:
an upper end connected to an upper portion of the vehicle body;
a lower end coupled to an end of the lower arm; and
a driving unit disposed on the lower arm and pushing or pulling the lower end of the shock absorber in a predetermined direction;
a lever hinge rotatably fixed to the lower portion of the vehicle body;
a lever disposed rotatably about the lever hinge, including a middle portion where a cam connected with the lower end of the shock absorber is formed; and
a fixing member fixing the cam of the lever and the lower end of the shock absorber.
2. The vehicle of claim 1 , wherein the driving unit includes:
a torque source generating a torque;
a lead screw coupled to the torque source and rotated by the torque of the torque source; and
a slider mounted on the lead screw and reciprocating along the lead screw.
3. The vehicle of claim 2 , wherein the toque source is a motor and includes a screw fixing member rotatably fixing the lead screw and slidably mounting the slider thereon.
4. The vehicle of claim 2 ,
wherein the lever further includes a lever end where a slider groove is positioned, the slider being inserted in the slider groove and the lever end being rotated about the lever hinge by the slider.
5. The vehicle of claim 1 , wherein the fixing member is a fixing bolt and fixes the cam to the lower end of the shock absorber.
6. The vehicle of claim 1 , wherein the driving unit is fixed to a side of the lower arm through a mounting bracket.
7. The vehicle of claim 1 , further comprising a cam rail having a rail that is formed in the cam rail with a predetermined curvature and receives the cam to guide the cam rotating about the lever hinge along the rail.
8. The vehicle of claim 1 , further comprising:
a vehicle height sensor sensing a height of the vehicle body; and
a controller controlling the driving unit in accordance with the height sent from the vehicle height sensor.
