FIELD: transportation.
SUBSTANCE: spring device contains a spring (120.1) of polymer material. The axially central portion (120.2) of the spring (120.1) located between the first end portion (120.3) ending with the first outer end surface (120.4) and the second end portion (120.3) ending with the second outer end surface (120.4) has radially narrowed section (120.5). The first end portion (120.3) of the spring has a recess extending axially from the first outer end surface (120.4) to the central portion (120.2) forming an axial cavity (120.7) in the spring body defined by a respective inner surface (120.8). A filler block (121) in contact with the noted inner surface (120.8) is inserted into the axial cavity (120.7) of the spring to change the rigidity of the spring device as compared to the initial state when the filler block (121) is not inserted into the noted axial cavity.
EFFECT: easy adaptation of the spring device to various vehicles.
