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. 

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

7.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.
