The utility model provides a position limiter assembly with the vibration attenuation function. The technical scheme of the position limiter assembly is that the position limiter assembly with the vibration attenuation function comprises a position limiter, a polyurethane limited block assembly and nuts, wherein mounting holes are arranged at the back part of the position limiter; and the polyurethane limited block assembly is fixed at the lower part of the position limiter through bolts. The position limiter assembly with vibration attenuation function has the benefits that the problem of breakage easily caused by 'iron-hit-iron' position limiter can be solved; the service life of the position limiter is prolonged; and meanwhile, polyurethane has the characteristics such as aging resistance, ozone resistance, grease resistance, and particularly has the characteristic of high elasticity under heavy pressure condition as a vibration attenuation buffer unit, so that the vibration attenuation and limitation can be combined effectively and perfectly.
