5. We also can produce base on client's drawings design
Trailer and semi-trailer air suspensions are more and more widely used in heavy tractor vehicles due to their unique advantages.
The trailing arm, as the guiding element in the air suspension system, plays a bearing and guiding role.
A two-piece air linker is usually used in the air suspension system of trailer and semi trailer, which is composed of a long guide arm 1 and a short guide arm 2 superimposed and fixed.
At the same time, there is also a single-leaf trailing arm with a single-leaf spring.
The air suspension device is applied between the frame and the axle. It includes a guide arm bracket, a bolt assembly, a spring guide arm and an air spring.
The guide arm bracket is connected to the frame, and the spring guide arm is fixed to the axle through the bolt assembly Above, the spring guide arm is a single piece structure,
one end of the spring guide arm is connected with the guide arm support, the other end of the spring guide arm is connected with the air spring by two bolts, and the end of the air spring away from the spring guide arm is connected with the car.
The frame is connected, a connecting beam is arranged between the two bolts, and a shock absorber is arranged between the bolt assembly and the guide arm support.
A semi-trailer with a single-piece guide arm air suspension device can reduce its own weight and reduce costs.
Applications
What's the leaf spring ?
Leaf springs are a simple form of suspension spring commonly used in vehicles, especially in the past.
It consists of one or more slender curved metal rods or "leaves" stacked on top of each other and fixed at the ends to a frame and axle.
When the vehicle encounters bumps or uneven road surfaces, leaf springs absorb impact forces and provide support, thereby improving the vehicle's ride comfort and handling.
Leaf springs have been used for centuries, dating back to horse-drawn carriages and early automobiles. They are essential for providing a smooth and controlled ride over rough terrain.
However, as technology has advanced, leaf springs in modern vehicles have been largely replaced by more complex suspension systems, such as coil springs and air suspension. Despite this, leaf springs are still used in some heavy-duty vehicles, including trucks, buses, and commercial vehicles, due to their durability and ability to support heavy loads.
The construction of a leaf spring usually involves multiple steel strips of varying lengths and thicknesses, with the longest strips forming the main blades and the shorter strips being called auxiliary blades.
The blades are clamped together and usually have an eyelet on each end for attachment to the vehicle. When the vehicle hits a bump, the blades flex and flatten to absorb the impact, then return to their original shape to provide continued support.
To sum up, leaf springs are a type of suspension spring used in vehicles to provide support, improve ride comfort, and absorb the impact of uneven road surfaces.
Although leaf springs have largely been replaced by more advanced suspension systems, they still play a vital role in the design of some heavy-duty vehicles due to their durability and load-carrying capabilities.
