Abstract

Spring-mounted vibration system to reduce vibration with a first spring-mounted part and a second spring-mounted part, wherein the first spring-mounted part and the second spring-mounted part can oscillate relative to each in at least one vibration direction and at least one of the spring-mounted parts can be exposed to a return force on a vibration movement. A control unit is arranged with at least one travel linkage which is connected with at least one of the spring-mounted parts and in which is arranged displaceably at least one guide element connected with a spring element generating the return force and/or the other spring-mounted part.

Claims

1. A spring-mounted vibration system for reducing vibration, the system comprising:

a lower portion having a guide;

an upper portion comprising

a first guide; and

a second guide;

a first scissor arm having a first end swivelly mounted to the lower portion and a second end slideably mounted to the first guide of the upper portion;

a second scissor arm having a first end swivelly mounted to a first location in the upper portion and a second end slideably mounted to the guide of the lower portion;

a lever arm swivelly mounted at a first end to the first location in the upper portion and slideably received to the second guide;

at least one damping element; and

a spring element having a first end mounted to the upper portion and a second end mounted to the lever arm in the second guide,

wherein a second end of the lever arm is located adjacent to the at least one damping element,

wherein the lever arm is configured to receive vibrations from the second scissor arm via the first location mounting.

2. The system of claim 1, wherein the second guide is curved.

3. The system of claim 2, wherein the lever arms is spring-loaded by the spring element.

4. The system of claim 3, wherein the at least one damping element is configured to reduce swivel movements of the lever arm.

5. The system of claim 4, wherein the at least one damping element comprises two damping elements located on opposing sides of the lever arm.

6. The system of claim 1, wherein the lever arm is slideably received at a middle section of the lever arm to the second guide.
