the axial left end of inner structural member 50 extends further out or to the left from the axial end of outer structural member 52 such that the entire axial cylinder 76 of outer structural member 52 is axially spaced from radial flange 72 of inner structural member 50 thus at the left side in fig2 outer structural member 52 is axially short of inner structural member 50 and this permits shear hub 66 to act as a cushion during high loads without affecting or causing shear stress in the bond between radial flange 72 of inner structural member 50 and elastomeric body 54 in a similar manner it can be seen that the axial right end of outer structural member 52 extends further out or to the right from the axial end of inner structural member 50 such that the entire axial cylinder 70 of inner structural member 50 is axially spaced from radial flange 78 of outer structural member 52 thus at the right side in fig2 inner structural member 50 is axially short of outer structural member 52 and this permits shear hub 66 to act as a cushion during high loads without affecting or causing shear stress in the bond between radial flange 78 of outer structural member 52 and elastomeric body 54 also as illustrated in fig2 elastomeric body 54 defines a relieved portion 82 disposed adjacent the inner end of radial flange 78 of outer structural member 52 to lower the stress on the bonding section between radial flange 78 and elastomeric body 54 during high loading.
