| Cab Rear Suspension Shock Absorber Information Table | |
| Category | Details |
| Official Name | Cab Rear Suspension Shock Absorber (with air spring assembly, commonly known as "Cabin Rear Airbag Shock Absorber") |
| Part Number | DZ15221440450 |
| Physical Parameters (Reference) - Maximum Length (Expanded) | Approx. 520 mm |
| Physical Parameters (Reference) - Minimum Length (Compressed) | Approx. 320 mm |
| Physical Parameters (Reference) - Working Stroke | Approx. 200 mm |
| Material | Composed of high-strength steel, aluminum alloy, and wear-resistant rubber air springs (airbags) |
| Shock Absorber Type | Twin-Tube Gas-Charged. This design includes a working cylinder and a reservoir cylinder, combined with air pressure regulation, providing a smoother damping feel than pure hydraulic systems |
| Integrated Airbag | Built-in air spring. It utilizes compressed air to provide variable stiffness, automatically fine-tuning the cab height according to the load to maintain horizontal balance |
| Material and Manufacturing Process - Piston Rod | Made of high-strength hardened steel with chrome plating. This process improves wear resistance and prevents oil seals from failing due to corrosion |
| Material and Manufacturing Process - Seals | High-performance, oil-resistant, and aging-resistant synthetic rubber (such as Neoprene) is used to ensure no air or oil leakage even under prolonged vibration |
| Material and Manufacturing Process - Cylinder Block Coating | The outer cylinder surface is typically coated with a black anti-rust coating, providing strong resistance to salt spray and sludge corrosion |

Performance Characteristics
1. Vibration Damping: Through the combined action of internal hydraulic damping and external air springs, it effectively absorbs bumps from the road surface, significantly improving ride comfort within the cab.
2. Height Adjustment: As part of the air suspension system, it can automatically or manually adjust the rear height of the cab within a certain range according to the load.
3. Durability: Designed for heavy-duty operating conditions, it maintains stable performance under harsh road conditions (such as mining areas and construction sites), extending the service life of related electronic components in the cab.
