Abstract

A blocking device for blocking a suspension strut of a motor vehicle for transportation of the motor vehicle. The suspension strut has a damper device and a helical spring. The helical spring is arranged between two spring plates and embraces at least one axial section of the damper device. The blocking device has a spacer body which is of substantially C-shaped design and can be fitted between the two spring plates to the damper device in a manner embracing an axial section on the latter.

Claims (12)

1. A blocking device for blocking a suspension strut of a motor vehicle for transportation of the motor vehicle,

the suspension strut including a damper device and a helical spring, the helical spring embracing at least one axial section of the damper device; and

the blocking device comprising a substantially C-shaped spacer body configured for fitting to the damper device in the axial section and embracing the damper device in the axial section, and a gripping element formed on said spacer body, said gripping element protruding radially outward through the helical spring when the blocking device is fitted to the suspension strut.

2. The device according to claim 1 , wherein the helical spring is formed with turns defining a clear width therebetween in an axial direction, and said spacer body has a height smaller than the clear width between two turns of the helical spring in a neutral position of the suspension strut.

3. The device according to claim 2 , wherein the height of said spacer body, measured in the axial direction of the damper device, is between 20 and 25 mm.

4. The device according to claim 1 , wherein said gripping element is a tear-off tab.

5. The device according to claim 1 , wherein said gripping element is arranged eccentrically with respect to said spacer body.

6. The device according to claim 1 , wherein said spacer body of formed with recesses on an outside thereof.

7. The device according to claim 1 , wherein said spacer body is shaped to enable a plurality of spacer bodies to be stacked axially.

8. The device according to claim 1 , wherein said spacer body is shaped to enable a plurality of spacer bodies to be stacked in an interlocking manner.

9. The device according to claim 1 , wherein said spacer body is formed with two C-limbs and a notch oriented orthogonally to said two C-limbs and arranged in between said C-limbs.

10. The device according to claim 1 , wherein said C-shaped spacer body is shaped to embrace the axial section of the damper device by more than 180°.
