The past 10 years JRZ struts and dampers are in use as applied to different brands of APC (armored personal carriers) vehicles all over the world to protect people while traveling from A to B.
The spring / damper units have been developed by Erik Ras to operate under the most difficult conditions and have been selected for the quality and perfect handling under the most severe terrain conditions while the suspension keeps the vehicle well controlled at high speeds and high vehicle weights.
This is achieved by:
This results in:
The gas pressure creates a lifting force. Because the piston rod diameter is 22 mm, the lifting force created is 3,8 kg/bar nitrogen pressure. Using 20 bar nitrogen pressure gives the damper a lifting force of 76 kg per corner. This lifting force works over the complete stroke, without adding spring rate to the system.
