### Common Types of Semi Trailer Axle Assemblies.

There are primarily two common types of semi trailer axle assemblies: the single axle assembly and the tandem axle assembly. The single axle assembly consists of one axle attached to the trailer, while the tandem axle assembly has two axles placed close together.

### Differences in Axle Placements.

In single axle assemblies, the axle is typically placed towards the rear of the trailer, while in tandem axle assemblies, the axles are placed closer to the center of the trailer. This placement helps distribute the weight more evenly and improves stability during transportation.

### Load Capacities of Axle Assemblies.

Single axle assemblies usually have a lower load capacity compared to tandem axle assemblies. Tandem axle assemblies are capable of carrying heavier loads due to the added support and weight distribution provided by the two axles.

### Differences in Suspension Systems.

The suspension system plays a crucial role in the performance of semi trailer axle assemblies. Single axle assemblies often have a simpler suspension system, while tandem axle assemblies may have more advanced systems such as air suspension for improved ride quality and load distribution.

### Overall Performance.

The choice of axle assembly can significantly impact the overall performance of the semi trailer. Tandem axle assemblies are preferred for heavy-duty applications where high load capacities are required, while single axle assemblies are suitable for lighter loads and shorter distances.

In conclusion, the key differences in semi-trailer axle assemblies lie in their types, axle placements, load capacities, suspension systems, and overall performance. Understanding these differences can help in selecting the most suitable axle assembly for specific transportation needs.
