Abstract

An adjustable strut (1) for motor vehicles. It includes a dashpot that comprises a piston accommodated in a shock-absorbing cylinder (2) accommodated in a helical spring (7). The piston divides the shock-absorbing cylinder into two chambers and is attached to a rod (8). The rod extends out of the shock-absorbing cylinder through an alignment-and-sealing package at one end. The rod is articulated to the wheel mass or carriagework at one end and the shock-absorbing cylinder to the complementary component at the other end. The helical spring is secured and tensioned between two cup springs. The first cup spring (5) is attached to the shock-absorbing cylinder by two height-adjustment cylinders that surround the latter concentrically. One height-adjustment cylinder slides in and out inside the other. The second cup spring (6) is attached to the piston rod in the vicinity of its articulation to the wheel mass or carriagework.
