Yutong Bus Parts Rubber Air Spring Assembly 229000112
The 229000112 air spring assembly is a core suspension component specifically designed for bus and truck chassis. As a key damping element in electronically controlled suspension systems, it operates on the core principle of compressed gas elasticity, replacing traditional coil springs to achieve multiple functions including load bearing, vibration damping, and vehicle attitude adjustment. It is suitable for various commercial vehicle chassis upgrades and spare parts replacement needs, and its stable performance and precise adaptability make it a preferred component for commercial vehicle suspension systems. The product uses high-quality composite rubber and multi-layer cord bonding technology to create a sealed airbag, connected with precision end plates to form a stable compressed air chamber. The core load is borne by the cord layer, the inner rubber layer is responsible for sealing, and the outer rubber layer combines sealing and protection functions, effectively resisting road gravel impacts, oil erosion, and extreme environmental aging, extending the product's service life. The overall structure has undergone rigorous dimensional calibration, with the inflation diameter tolerance controlled within ±10.0 mm. The interface threads conform to GB/T 196 standard, with a thread clearance of no more than 0.15 mm, ensuring precise fit with the chassis mounting position. Assembly is convenient, allowing direct replacement of existing parts and significantly reducing maintenance and replacement costs and time. In terms of performance, this air spring assembly possesses excellent airtightness and stiffness adjustment capabilities: maintaining pressure at an initial pressure of 0.75 MPa for 24 hours results in a pressure drop of no more than 0.02 MPa; immersion in (23±5)℃ clean water for 2 hours without water bubble leakage ensures no leakage risks during long-term use; both static and dynamic stiffness deviations are no more than ±15%, and the natural frequency can be flexibly adjusted within 1.0 Hz to 1.8 Hz. Utilizing nonlinear stiffness characteristics, it can dynamically adjust its stiffness according to changes in vehicle load, ensuring the suspension frequency remains basically stable under different loads, significantly improving driving comfort while reducing the probability of impact with the limit block. This product boasts excellent vibration damping and high/low temperature adaptability, effectively filtering high-frequency road vibrations, improving in-vehicle sound quality, and reducing the transmission of bumps. It protects vehicle chassis components from impact damage, enhances the passenger experience, and effectively protects onboard precision instruments and electrical equipment. With strong high/low temperature adaptability, it can operate stably in environments ranging from -40℃ to high temperatures. The rubber material maintains good elasticity, without cracking or aging, making it suitable for various complex road conditions and climates. Whether on urban roads, highways, or bumpy rural roads, it provides stable vibration damping and load-bearing performance. As a dedicated spare part for bus and truck chassis, the 229000112 air spring assembly is manufactured in strict accordance with DV&PV testing standards. Each product undergoes rigorous testing for airtightness, stiffness characteristics, fatigue strength, and other aspects to ensure product quality meets standards and stable, reliable performance. It effectively reduces the frequency and cost of vehicle maintenance, extends the vehicle's lifespan, and reduces the impact on the road surface. Combining practicality and economy, it is an ideal choice for commercial vehicle chassis maintenance and upgrades.
