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, comprising:

first and second spring-mounted parts configured to oscillate relative to each other in at least one vibration direction, wherein;

at least one of the spring-mounted parts is configured to be exposed to a return force on a vibration movement; and

at least one of the spring-mounted parts has a first groove; and

a guide displaceably arranged movable within the first groove of the at least one of the spring-mounted parts and connected with a spring generating at least one of the return force of the spring or movement of the other spring-mounted part; and

a second groove,

wherein at least one of the first groove or the second groove is formed such that for a forward vibration movement it has a substantially linear first course section and a second course section rising with a first gradient value in relation to the first course section,

wherein at least one of the grooves is configured with a falling third course section, the gradient value of which as a second gradient value is greater than the first gradient value, for the transition from the forward vibration movement to a rearward movement.

2. The spring-mounted vibration system according to claim 1, wherein the first groove is curved in relation to the vibration direction.

3. The-mounted vibration system according to claim 1, wherein at least one of the grooves is configured with a substantially linear fourth course section and a fifth course section falling with the first gradient value in relation to the fourth course section for the rearward vibration movement.

4. The-mounted vibration system according to claim 1, wherein at least one of the grooves has a rising sixth course section, the gradient value of which corresponds to the second gradient value, for the transition from the rearward vibration movement to the forward vibration movement.

5. The spring-mounted vibration system according to claim 1, wherein the guide moveable within the first groove interacts with at least one component reproducing the vibration movement.
