The invention provides a double-layer rubber spring and an air spring using the double-layer rubber spring, and belongs to the field of air springs. The double-layer rubber spring comprises an upper-layer outer sleeve, an upper-layer partition plate, an upper-layer core shaft, an upper-layer rubber, a lower-layer outer sleeve, a lower-layer partition plate, a lower-layer core shaft and a lower-layer rubber, a limiting ring is arranged at the upper end of the lower-layer separation plate, the limiting ring can contain the lower end of the upper-layer partition plate, a circle of boss is arranged on the outer side of the lower-layer outer sleeve, a circle of groove is formed in the outer side of the upper-layer outer sleeve, a boss of the lower-layer outer sleeve can be contained in the groove of the upper-layer outer sleeve, a circle of boss is arranged on the outer side of the lower core shaft, a circle of groove is formed in the outer side of the upper core shaft, a groove of the upper-layer core shaft can contain a boss of the lower-layer core shaft, a circle of gap interval with an oval cross section is arranged between the upper-layer rubber and the lower-layer rubber, the upper rubber is made of natural rubber, and the lower rubber adopts modified chloroprene rubber. The double-layer rubber spring has the beneficial effects that the requirement of the air spring for stress is met, the requirement for the fireproof performance of the EN45545 by the air spring is met, and the installation and the maintenance are convenient.
