Heavy-duty Shock Absorber Design

Introduction:

Heavy-duty shock absorbers have several design features that provide improved durability compared with conventional shock absorbers.

 

Heavy-duty shock absorber

 

Some heavy-duty shock absorbers have a dividing piston in the lower oil chamber. The area below this piston is pressurized with nitrogen gas to 360 pounds per square inch (psi), or 2,482 kilopascals (kPa). Hydraulic oil is contained in the oil chamber above the dividing piston. The other main features of the heavy-duty shock absorber are:

 

1. High-quality seal for longer life.

2. Single tube design to prevent excessive heat buildup.

3. Rising rate valve to provide precise spring control under all conditions.

 

The operation of the heavy-duty shock absorber is similar to that of the conventional type
