Embodiment Construction
[0031] Attached below Figure 4 to Figure 11 Embodiments of the present invention are described in detail.
[0032] The rubber pad used for series coil springs consists of a metal top plate 3, an elastic rubber body 2 and a metal bottom plate 1 from top to bottom, the metal top plate 3 and the metal bottom plate 1 are vulcanized and connected by the elastic rubber body 2, and the middle position of the top surface of the metal top plate 3 Fixing the metal ring 4 used for positioning the coil spring is characterized in that the part where the bottom surface of the metal top plate 3 is connected with the elastic rubber body 2 is an upwardly recessed upper circular arc surface 31, and the top surface of the metal bottom plate 1 is in contact with the elastic rubber body 2. The part connected by the rubber pad 2 is the lower arc surface 11 protruding upwards, and the upper arc surface 31 and the lower arc surface 11 are coaxial arc surfaces arranged longitudinally along the horizo...
