Mechanical Suspension More Information ( Just for Reference) :

1.The front, middle and rear spring hangers are made of high tensile low alloy steel plates (pressed and welded into structure) stronger but lighter than the old type.

2.The new design prevents the spring from shifting in a side way during running, The 90mm wide steel spring is made of high quality material.

3. The antifriction block (welded) is made of high tensile steel plate material (or #20cast steel) .

4. Its angle is in line with the unfolding direction between the steel plate spring and the antifriction block of the rocker arm.

5. The angle of the torque arm is scientifically adjusted. It can efficiently reduce the instant sliding distance between the tires and the ground, effectively lower friction of the tire, and increase the tire service life.

7.The torque arm bushing is made of urethane rubber. It has a buffering function to the instant abrasion in sliding shift of the tire.

8.The above features, plus a correct installation, reliably guarantee the verticality between the axle and the king pin, effectively remove the phenomena of offset abrasion and gnawing, and make the tire wearing even.

The difference between trailer suspension and semi-trailer suspension

Ordinary semi-trailer body, axles and suspension systems, axle and suspension system located at the base of the body, among them,the axle is a barbell, on both ends of the axle set wheels, the lateral set on the bottom of the body, between the body and the axle suspension system to connect the axle and the body: when the body drag force, the body through the suspension system located at the ends of the axle wheel movement.
Semi-trailer plate spring suspension (plate spring suspension for short) is divided into less plate variable cross-section steel suspension and constant cross-section multi-plate spring suspension.At present, more than 95% of the domestic heavy truck suspension system is based on the plate spring as the elastic element and guide device of the non-independent suspension, its main advantages are simple structure, easy manufacturing, convenient maintenance, mature technology, reliable work.
