ABSTRACT:
A rubber sleeve spring includes an internal part 1 an external part 2 which encloses the latter radially spaced-apart and a spring body 3 made of an elastomeric material which is disposed in the gap formed by this space and adhesively connected to the internal part 1 and the external part 2 and the spring body encloses at least three connecting arms 4, 5, 6 between the internal part 1 and the external part 2. At least one of the connecting arms 4, 5, 6 is completely separated by a separation 7 in at least one partial area of its longitudinal extension between the internal part 1 and the external part 2 and the separation 7 basically extends parallel to the longitudinal direction of the internal and external parts 1, 2 and at least one insert 8 is provided which is inserted in the separation 7 while generating an elastic preload in the components of the respective connecting arm 4, 5, 6 adjacent to both sides of the separation.
