Resistant to heavy loads American Type Leaf spring trailer suspension

The American Type Leaf spring trailer suspension produced and sold by DARO Group is composed of several pieces of alloy spring steel of varying lengths. When deformed under load, each piece will slide relative to each other and produce friction, resulting in a certain resistance, which leads to vibration attenuation of the body. It has the characteristics of simple, cheap, strong load capacity and strong durability.

American Type Leaf spring trailer suspension works:

When the vehicle is driving on the uneven road condition, the wheel bump drives the axle to jump, and the leaf spring and the lower end of the shock absorber move up at the same time. The length of the leaf spring will increase during the upward movement, which is coordinated by the extension of the lifting lug; When the upper end of the shock absorber is fixed and the lower end is moved up, it is equivalent to being in a compressed state, damping is increased and vibration is attenuated. When the runout on the axle exceeds the distance between the buffer block and the limit block, the buffer block and the limit block contact and compression occurs.

Application Scenario


American Type Leaf spring trailer suspension


American Type Leaf spring trailer suspension has the advantages of simple structure, low cost and maintenance, strong rigidity, and high load-bearing capacity. Leaf spring has the guiding function and can transmit forces and torrents in all directions. The reed can also be combined in a certain way to make the plate spring present linear or non-linear elastic characteristics, so it is still widely active in medium or heavy transport vehicles.


Package & Delivery

Common leaf spring suspension can be divided into multi-leaf spring suspension, less leaf spring suspension, main and auxiliary composite suspension, some owners believe that the leaf spring suspension is composed of a stack of steel plates, should not be too fragile, so in use will not pay attention to the protection of the suspension, this understanding is actually wrong, leaf spring suspension also needs to do daily maintenance and repair.
