different axle oil stretched spring cylinders link up play balance shaft bearing results.

  Enhanced Oil stretched spring pressure to accumulator with steel tube as an elastic element , able to accept very high pressure , generally up to 20MPa, therefore , small size, light weight, axle load for heavy duty steel stretched spring when the mass ratio of the light 50 % or more.
    electric pallet trucks balance shaft bearing pneumatic suspension system can converge through the pipeline , different axle oil stretched spring cylinders link up play balance shaft bearing results.
    Progressive small crane travels ride hydrocarbon stretched spring can get excellent elasticity characteristic curve and lower natural frequency, so small crane traveling ride and comfort is greatly superior to steel stretched spring suspension, and reduced vehicle the impact on the ground . Small crane pneumatic suspension variable stiffness elastic characteristic curve can avoid attacks suspension breakdown on cross-country road is very important.
    Add a small crane roll stiffness when the vehicle is turning, because the effect of centrifugal force , moving the center of gravity , so small crane significantly skewed. Small crane pneumatic suspension system will be left and right oil stretched spring series , can greatly enhance vehicle roll stiffness . Pneumatic suspension cylinders best selection of large and small lumen area ratio can be obtained aspiring roll stiffness . Similarly, the front and rear cylinder gas stretched spring series , can improve the whole vertical angular stiffness to overcome the brake to allow representation .
