Air spring which includes a vibration absorbing mass

An air spring for supporting a vehicle body on a vehicle component to which vibrations are imparted in a predetermined resonance frequency range, the air spring comprising:

• an air spring flexible member charged with pressurized air and having first and second ends;
• a first attachment part mounted on said vehicle body and a second attachment part mounted on said vehicle component;
• said first and second ends of said air spring flexible member being attached to said first and second attachment parts, respectively;
• vibration absorbing mass means elastically connected to said second attachment part for reducing said vibration in said resonance frequency range;
• said second attachment part being a roll-off piston mountable on said vehicle component;
• said vibration absorbing mass means including a vibration absorbing mass;
• and, elastic means for elastically mounting said vibrations absorbing mass in said roll-off piston;
• said roll-off piston defining an enclosed space and having a support projection disposed therein and said support projection being disposed concentrically with respect to said roll-off piston;
• said elastic means being an elastomeric body mounted on said support projection;
• and,
• said vibration absorbing mass including an annularly-shaped vibration absorbing mass mounted on said elastomeric body.
