DEVICE COMPRISING SPRINGS, WITH CONTROLLED RIGIDITY

摘要

The invention relates to a device (1) comprising springs, with controlled rigidity, for a motor vehicle. The device (1) comprises a support (12) for a spring (11), comprising a magnetic body of the electromagnet type, and a magnetic plate for actuating a means for tightening the support along a guiding rod (13). The magnetic body can be controlled in order to generate a magnetic force actuating the tightening means. The assembly can thereby block the spring (11) and adapt the rigidity of the device (1) according to the driving information.
