Quality Drives-The benefits of Sensitive Damping Control technology.
Shock absorbers play a critical role in the safety of the vehicle and studies reveal that an average car would go through at least one set of replacement shocks during its lifetime. Over time, shock absorbers deteriorate owing to several factors:
· Road unevenness like potholes and ground waves
· Damage of the piston by salt residue, stones and water
· General wear and tear
· Old or worn/damaged repair kits (bump stops) or missing protective gaiters
These can lead to common faults in the shock absorber and mounting, such as:
· Oil leaks: while a misting’ of oil on the outer tube is normal, larger volumes indicate a failing piston rod seal
· Worn mountings: a compliant rubber-to-metal component, mountings prevent the transfer of damping and suspension forces
from transferring to the cabin and a deteriorated part makes this more prevalent
A worn shock absorber could reduce cornering stability during sudden evasive manoeuvres, increase the risk of aquaplaning, increase stopping distance by 2 to 3 metres (at 50mph) and reduce traction considerably. The aim in shock absorber replacement should be to restore the vehicle to its original operating characteristics, while giving due consideration to other suspension components which might need replacing at the same time.
Sensitive Damping Control (SDC) is a self-contained damping system using two valves to distribute the damping characteristics, which is used on numerous Boge shock absorbers. While one of the valves is fixed to the piston rod and continuously dampens motion, the second valve is suspended between two springs which allows for a certain amount of play and only works when extra damping force is required. At full stroke, the movable valve also contributes to the overall valve performance in addition to the first and thus increases the damping for the vehicle body and axle, increasing driver comfort and safety.
