The invention discloses a rubber suspension with a rigidity compensation function. The rubber suspension comprises a first limiting cover, a core, a rubber main spring, a framework and a tray, wherein a rigidity compensation mechanism is arranged in the tray and comprises a limiting ring, a second limiting cover, a first fixing plate, a second fixing plate and springs; the bottom of the limiting ring is connected with the bottom of the tray; the second limiting cover is arranged on the outer side of the limiting ring; the second limiting cover and the limiting ring are fixedly pressed in the tray through the framework; the first fixing plate is fixedly arranged in the second limiting cover; the second fixing plate is arranged in the limiting ring and is stressed to move up and down along the inner side of the limiting ring; and the springs are positioned between the first fixing plate and the second fixing plate and are fixedly connected with the first fixing plate and the second fixing plate. The rubber suspension has the advantages that rigidity compensation can be realized, so that the rigidity in a linear section is high; and meanwhile, a power assembly is limited in a certain displacement range and is prevented from colliding with other mechanisms due to extremely large displacement.
