ABSTRACT:

BACKGROUND OF THE INVENTION
This application claims the priority of German application No. 197 51 215.1, filed Nov. 19, 1997, the disclosure of which is expressly incorporated by reference herein.
The present invention relates to an arrangement for blocking a spring in a vehicle spring strut, and more particularly, to a spacer element for transporting the vehicle.
DE 28 22 105 A1 discloses a method influencing the spring travel of a coil spring of a spring strut for a motor vehicle by way of spacers. These are held on a plate by screws and are in each case clamped between coils of the spring.
SUMMARY OF THE INVENTION
An object of the present invention is to provide an arrangement for a spring on a spring strut of a motor vehicle which, by way of a simple handling, permits a complete blocking of the spring for the purpose of transport.
According to the invention, this object has been achieved by providing the spacer element consists of at least one segment which can be snapped into the spring and is supported by means of a lower free end on a stationary spring plate of the spring strut.
Principal advantages achieved by the invention includes the spacer consisting of a segment made of a hard-elastic plastic material which can be rapidly snapped into the spring and can easily be removed again.
The snapping into the coils of the spring takes place in one or several bearing receiving devices of the spacer element such that an upper receiving device is used as a threading receiving device and the spacer element is swivelled about this bearing onto the stationary spring plate of the spring strut and is supported here. The support preferably takes place in a receiving groove of the spacer element. A receiving device in the spacer element for bearing the spring coil is constructed in the vertical direction in the shape of an oblong hole for compensating tolerances, whereas the threading receiving device has a circular cross-section.
So that the snapping-in and snapping-out with respect to the spring can be carried out in an unimpaired and rapid manner, corresponding insertion slopes are provided for receiving the spring coils.
Furthermore, for receiving the coils in the receiving devices, inserting ducts are provided which have a lower height than the receiving devices themselves so that, after taking up a locked position, the spring coils will remain caught in the receiving devices.
For the precise adaptation of the spacer elements to the spring construction, the receiving devices have a correspondingly adapted curved and tilted course or shape.
