Embodiment Construction

[0025] refer to figure 1 and figure 2 An exemplary embodiment is described wherein a simple suspension 100 is depicted. In the example shown, the object 130 is suspended on the frame 200 by two suspension elements, namely the first suspension element 110 and the second suspension element 120 , respectively. The first suspension element 110 and the second suspension element 120 are bonded to the object 130 by a bonding interface 132 which is depicted in the figures as simply connecting the suspension elements 110, 120 to the object 130 in parallel. platform. The suspension elements 110, 120 may also be arranged on both sides of the object 130, wherein the frame 200 may surround the object 130 (not shown). Bonding interface 132 is connected to, or forms part of, mass 131 to be suspended on frame 200 . In the example depicted, mass 131 forms nearly the entire mass of object 130, where bonding interface 132 is assumed to be massless. In addition to "suspension", the novel co...

Abstract

A simple and robust suspension arrangement(100) is provided for taking into account different suspension modes without the need for excessive sensoring or electronics. The novel suspension arrangement (100) includes a first suspension element (110), which directly suspends the object (130) to the frame (200), and a second suspension element (120), which suspends the object (130) to the frame (200) through a magnetic coupling (140) between the object (130) and the second suspension element (120). The magnetic coupling(140) provides a magnetic coupling force (Fh) to act as a threshold such that the suspension arrangement (100) is designed to magnetically decouple the second suspen-sion element (120) from the object (130) when the excitation force (Fe) transmitted between the frame (200) and the object (130) exceeds the magnetic coupling force (Fh).

Description

technical field [0001] The invention relates to a suspension device. More specifically, the invention relates to a suspension device according to the preamble of claim 1 . Background technique [0002] Suspending an object from a frame is a compromise between stability and comfort. To protect equipment, people, or structures (eg, vehicles) against shock, the suspension should be soft enough to absorb impact forces between the frame and the suspended object. In most applications, however, soft isolation cannot be used alone, since increased isolation to the maximum usually makes the object unstable, thus preventing its normal use. On the other hand, during normal operation, the suspension between the object and the frame should be rigid in order to maintain stability and prevent the isolated or suspended person from vomiting due to low frequency oscillations. For example, let's look at the suspension on a vehicle. During driving on slippery roads, the suspension is prefer...
