AI Technical Summary
Existing magnetorheological damper guides exhibit high frictional noise and poor durability at the piston rod and oil seal point, with significant frictional temperature rise, limiting the expansion of piston rod diameter.
The lubricant reservoir is filled with dry powder or a mixture of dry powder and grease. The filling volume of the lubricant reservoir is 1/2 to 4/5. The particle size of the dry powder is larger than that of the grease molecules. It fills the micro-deformation on the surface of the shock absorber connecting rod, avoids the loss of lubricating medium, and reduces frictional resistance and temperature.
It significantly reduces lubricant loss, lowers frictional resistance by 30%, reduces frictional temperature by 15%, improves the durability of oil seals and guides by 20%, and allows for the use of larger diameter piston rods, expanding product specifications.
