SHOCK ABSORBER AND VEHICLE CONTAINING IT Russian patent published in 2017 - IPC F16F9/48 B60G17/08 

FIELD: transportation.

SUBSTANCE: shock absorber contains the device for creating the damping force. The minimum length parameter indicates the hard state in the range (Aa0) during expansion, when the piston rod is pressed inward of the cylinder deeper, than the specified minimum length position (Sa1). The maximum length parameter indicates the soft state in the range (Aa4) during expansion, when the piston rod protrudes from the cylinder further, than the specified position (Sa4) of maximum length. The expansion side parameter between the specified position (Sa1) of the minimum length and the specified position (Sa4) of maximum length includes the parts (Sa1-Sa2, Sa3-Sa4). The part (Sa1-Sa2) indicates the higher change rate in the damping coefficient relative to the piston rod stroke. The part (Sa2-Sa3) indicates the lower change rate in the damping coefficient. The shock absorber of the second embodiment is configured with the damping force characteristic in which the change rate of the compression damping coefficient is larger in the maximum length position area. The vehicle contains the shock absorber, only the rear wheel is equipped with it.

EFFECT: improvement of the damping characteristic.
