falls below the initial static position. Using the drive 5, the screw support 3 is screwed into the spring 2 and simultaneously unscrewed from part 4. Due to the difference in the steps of the screw support 3 and the turns of the spring 2 in a compressed state, part 4 returns to its original static position. After the alignment of the indicators 6, the screwing of the support 3 into the spring 2 ceases. At the same time, the number of working turns decreases, the rigidity of the spring 2 increases and is aligned with the mass of part 4. This allows you to maintain the natural frequency of part 4 on the spring, which is equal to the frequency of the original static 384417

koy load. As the static load on the suspension decreases, part 4 rises above the initial static position. The screw support 3 is unscrewed from the spring 2 by means of the drive 5 and simultaneously screwed into part 4. Due to the difference in the steps of the screw support 3 and the turns of the spring 2 in the compressed state, part 4 returns to its original static position.

The invention relates to vehicle spring suspensions, in particular to methods for adjusting them.

The purpose of the invention is to stabilize the suspension characteristics.

The drawing shows the scheme of the suspension of the vehicle for the implementation of the proposed method.

Vehicle suspension mounted on the base of a cylindrical spring 2, a screw support 3 screwed into the spring 2 and into one part 4 of the vehicle, the screw support drive 5 and the static position indicators 6 of the part 4, In the static position the indicators 6 are aligned, the spring stiffness 2 corresponds to its static load. In this part of the vehicle 4 has a certain frequency of oscillation on the spring.

The method for adjusting the vehicle's spring suspension is as follows.

With an increase in the static load on the suspension, part 4 of the vehicle falls below the initial static position. Using the drive 3, the screw support 3 is screwed into the spring 2 and simultaneously screwed out of part 4. Due to the difference in the steps of the screw support 3 and the twist of the rod

in compressed state, part 4 returns to its original static position. After combining the indicators 6, the screwing of the support 3 into the spring 2 is stopped, and the number

the work of their turns decreases, the stiffness of the spring 2 increases and is aligned with the mass of part 4. This allows you to save the natural frequency of part 4 on the spring,

equal to the frequency at the initial static load.

With a decrease in the static load on the suspension, part 4 rises above

of the initial static position, the Band-Aid support 3 is driven by the actuator 5 from the spring 2 and simultaneously screwed into part 4. Due to the difference in the steps of the screw support 3 and

coils of the spring 2 in the compressed state part 4 returns to its original static position. After combining the indicators 6, the unscrewing of the support 3 from the spring 2 is stopped, this reduced mass of part 4 corresponds to the proportionally reduced stiffness of the spring 2 containing the increased number of turns.

The claims of the parts of the vehicle connected by it, which distinguishes The method of adjusting the spring so that, in order to stabilize the vehicle's suspension, it is a suspension characteristic that is screwed in bringing its stiffness to the support at the same time from the one in accordance with the static load part of the vehicle screw into the spring or screw the other turns, block them with the help in the indicated part and unscrew from the screw support fixed on one to the spring.
