Excel-G (Twin tube gas) in Gas-A-Just (Mono-tube gas).Excel-G model se je prej imenoval Super. A ve kdo kaka je razlika? Twin tube vs. Mono tube ? Izkušnje z KYB amortizerji?
1. MONOTUBE SHOCKS
As the name implies, a monotube shock is designed with a single cylinder but it has two pistons. One piston is attached to the piston rod and moves up and down in the cylinder along with the rod. Fluid passes back and forth through valves in this piston. The second "floating piston" is located lower in the cylinder, with hydraulic fluid above it and high pressure Nitrogen gas supporting it from below. As the upper piston travels the length of the cylinder, the floating piston moves up and down slightly, following the change in pressure in the upper portion of the cylinder. The cushioning effect of the floating cylinder allows KYB engineers to create a very smooth transition between the response for comfort and control. This allows KYB engineers to create shocks that offer very high performance handling and, at the same time, deliver excellent ride comfort. Due to the high-pressure gas in the cylinder, monotube shocks will have an effect on the height of the car at rest. If a monotube shock has leaked or lost its charge, it will usually have a noticeable effect on the vehicle's height.
2. TWIN TUBE SHOCKS
Most of today's shocks and struts are twin tube designs. Twin tube shocks are constructed with one cylinder surrounding another. The inner cylinder is the "working cylinder" where the piston and rod move up and down. The outer cylinder serves as a hydraulic fluid reservoir.
There are valves both in the piston and at the base of the shock. The valves at the base of the shock allow fluid to flow in and out of the outer cylinder. By tuning the performance of both the upper and lower valves, KYB engineers can produce a shock that delivers excellent ride comfort yet still maintains good control when sudden changes in the road surface are encountered.
