Problems solved by technology
However, the load-deflection curve of the traditional air spring presents an inverse "S" shape, which has a linear stiffness characteristic in the normal operating range, and has a stiff spring's nonlinear stiffness characteristic in the stretched or compressed edge region. On the other hand, Once an air spring is designed, its stiffness and damping characteristics are difficult to adjust
Due to the shortcomings of traditional air springs such as single stiffness and damping characteristics, unsatisfactory characteristic curves, and limited application effects, the application range of air springs is limited.

The invention discloses a novel air spring for two-grade rigidity self-adaptive adjustment. The novel air spring comprises a support base, a rubber airbag, an air spring cover plate and an additional air chamber, and further comprises a limiting block 1 and a limiting block 2 respectively arranged at the top of the support base and the inner surface of the top of the additional air chamber, an intake valve pressure adjusting mechanism and an exhaust valve pressure adjusting mechanism; an intake valve throttling hole and an exhaust valve throttling hole are formed in the air spring cover plate; and the intake valve pressure adjusting mechanism and the exhaust valve pressure adjusting mechanism are arranged below the intake valve throttling hole and above the exhaust valve throttling hole. The novel air spring is simple and small in structure, uses the intake valve and the pressure adjusting mechanism thereof, the intake and exhaust valve throttling holes and the additional air chamber for preferably solving the problems of single rigidity and damping characteristics, weak characteristic curves and limited application effects of a traditional air spring, and can achieve an ideal effect in various application places.
Description
technical field [0001] The invention belongs to the technical field of air springs, in particular to a novel air spring with two-stage stiffness adaptive adjustment. Background technique [0002] The air spring is a non-metallic spring that uses the compressible nature of air to achieve elastic action, and has functions such as buffering, shock absorption and actuation. When the air spring is elastically deformed, the air spring uses the sum of the support reaction force of the compressed gas inside and the reaction force generated by the change of the effective pressure bearing area of the air bag to provide elastic force. [0003] The elastic medium of the air spring is a compressible gas, and its stiffness and damping characteristics can be designed according to the application requirements. However, the load-deflection curve of a conventional air spring exhibits an inverse "S" shape, which has a linear stiffness characteristic in the normal operating range, and a non-...
