The picture
Air Springs
Rubber air springs use rubber elasticity and air pressure to obtain comprehensive shock absorption, shock absorption, shock isolation, noise prevention and cushioning performance. According to the sealing structure, it is divided into four categories: pressure self-sealing type, rim clamping type, hoop sealing type and hybrid type. The load of the rubber air spring is mainly borne by the cord, and the number of layers of the cord is mainly composed of 2 layers. The product is required to consist of 4 layers of cord. The inner layer of rubber is mainly used for sealing, and the outer layer of rubber is not only for sealing, but also for protection.
This rubber air spring can be used in vibration damping equipment. It can better achieve vibration isolation and ensure the safety and stability of the base and control system of the vibration equipment by utilizing the characteristics of high frequency vibration isolation, sound insulation and low natural vibration frequency. Such as vibration isolation of vibrating screens, vibration reduction of luxury vehicle seats and other equipment.
