The present invention relates to a suspension having a variable spring constant, comprising: first and second bearing tables arranged to be spaced from each other; a third bearing table arranged between the first and second bearing tables so as to be able to move between the first and second bearing tables; a main spring having one end and the other end coupled to the first and second bearing tables, respectively; a first auxiliary spring, which is arranged to be spaced from the main spring, and which has one end and the other end coupled to the first and third bearing tables, respectively; and a support unit, which has one end coupled to the first bearing stand, and which is formed to extend from the first bearing table towards the second bearing table, wherein the support unit comprises a fastening unit arranged to be adjacent to the other end of the support unit. According to another embodiment, the fastening unit further comprises a first pressure provision unit operated by a control unit, and the control unit controls the fastening unit such that the third bearing table is separably coupled to the support unit, thereby providing a different spring constant according to whether the third bearing stand is coupled or not.

    La présente invention concerne une suspension présentant une constante de rappel variable, comprenant: des première et deuxième tables de support agencées de manière à être espacées l'une de l'autre; une troisième table de support agencée entre les première et deuxième tables de support de manière à pouvoir se déplacer entre les première et deuxième tables de support; un ressort principal dont une extrémité et l'autre extrémité sont accouplées aux première et deuxième tables de support, respectivement; un premier ressort auxiliaire, qui est agencé de manière à être espacé du ressort principal, et dont une extrémité et l'autre extrémité sont accouplées aux première et troisième tables de support, respectivement; et une unité de support, dont une extrémité est accouplée au premier montant de support, et qui est formée pour s'étendre à partir de la première table de support en direction de la seconde table de support, l'unité de support comprenant une unité de fixation agencée de manière à être adjacente à l'autre extrémité de l'unité de support. Selon un autre mode de réalisation, l'unité de fixation comprend en outre une première unité de fourniture de pression actionnée par une unité de commande, et l'unité de commande commande l'unité de fixation de sorte que la troisième table de support soit accouplée de manière amovible à l'unité de support, ce qui permet de fournir une constante de rappel différente selon que le troisième montant de support est accouplé ou non.
