Definitions

  • the present invention aims to overcome the above disadvantages of the prior art.
  • FIGS. 8A and 8B show a longitudinal sectional diagram of a detonated damper according to the second embodiment of the invention when the stroke of the damper piston exceeds a third expansion stroke in the damper cylinder as well as that a graph of the arrangement of the components of the detacher damper corresponding to the position of the piston marked in Figure 8A.
  • deflections of the wheel in attack or relaxation corresponding to the races in piston attack 3 of the damper 1, between - 15 mm and -50 mm from the reference base AR
  • displacements of the wheel in attack or in expansion corresponding to the strokes of the piston 3 of the shock absorber 1, between 15 mm and 50 mm from the reference base AR
  • medium energy displacements DME which represent solicitations also frequent.
  • the floating piston 15 of the hydraulic expansion stop is moved and simultaneously compresses the spring constituting the mechanical expansion stop 16 when the expansion stroke of the piston 3 of the damper 1 exceeds a value of about 70 mm, to quickly brake the piston 3 of the damper 1 in its corresponding cylinder 2.
  • the overall section of a smaller number of holes 13 through the cylinder 10b of the hydraulic thrust 9b decreases because an increasing number of through holes 13 are plugged by the piston 1 1 b of the hydraulic thrust bearing 9b as the cylinder 10b moves around the piston 1 1 b of the abutment hydraulic drive 9b towards the lower bottom wall 12 of the cylinder 2 of the shock absorber 1: this ensures a more abrupt braking of the piston 3 of the detuned damper 1b in order to protect the body 6 and the chassis of the vehicle .
