Tandem axle trailer suspension
Tandem axle trailer suspension,is the preferred suspension for heavy-duty trucks, with a simple structure, low cost of construction and maintenance, strong rigidity, and high load-bearing capacity. The leaf spring has a guiding function, which can transmit forces and moments in all directions. The spring can also make the leaf spring show linear or nonlinear elastic characteristics according to a certain combination mode.
Equalizer bush: bronze/mixed material

Equalizer thickness: 10MM,12MM for option
Torque arm: 28mm,36mm
Products Description
Tandem axle trailer suspension,is composed of multiple reeds with different lengths and consistent widths, and the length of the reeds increases sequentially from bottom to top. The bottom reeds are the shortest, forming an inverted triangle that fully utilizes the force principle of the triangle. The structure is simple, and the maintenance cost is also low. The number of reeds is closely related to the load-bearing capacity. The more the number and thickness of reeds, the stronger the rigidity of the reeds, and the higher the load-bearing capacity.
Tandem axle trailer suspension’s working principle:
When the vehicle is running on the uneven road, the wheel bump drives the axle to jump up, 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 in the process of upward movement, which is coordinated by the extension of the lifting lug; The shock absorber is fixed at the upper end and moves up at the lower end, which is equivalent to being in a compressed state. The damping increases and attenuates the vibration. When the jumping force on the axle exceeds the distance between the buffer block and the limit block, the buffer block and the limit block come into contact and compress.
Application Scenario
Tandem axle trailer suspension can be divided into multi leaf spring suspension, few leaf spring suspension, main and auxiliary composite suspension, gradual stiffness leaf spring. Multi leaf spring suspension is commonly used in heavy-duty vehicles, and few leaf spring suspension is mostly used for standardized transportation.
