SELECTING THE PROPER TRAILER AXLE
When selecting an axle for your application remember to consider the following important specifications:

  • LOAD CAPACITY:  the load rating of the axle must support the maximum gross vehicle weight rating. For multiple axle trailers divide the GVWR by the number of axles to determine the minimum load capacity of each axle.

  • TRACK LENGTH:  measure your axle track length by determining the distance between the center of 1 tire to the center of the other tire. A more precise measurement can be made by measuring the distance from 1 ‘HUB FACE’ to the other. The hub face is also known as the mounting surface where the wheel studs are located.

  • SPRING CENTERS:  measure the distance from the center of 1 spring to the center of the other.
    NOTE: not required for replacement torsion axles

  • OVERALL LENGTH:  measure the distance from the very end of an axle’s spindle to the very end of the opposite spindle.

  • AXLE STYLE:  important when reusing old mounting hardware and also for proper tire clearance. Includes straight axles (round or square), drop axles with offset spindles, and torsion axles. Also consider spindle size when reusing existing hubs or drums.

  • AXLE CAMBER:  Most trailer axles are designed with a bend in the tube that will deflect when the load (weight of the trailer) is applied. This will theoretically bring the trailer wheel camber toward a 0 value that is the best setting for most trailer applications. This will allow the tires to wear evenly and allow the longest tread life. Camber can be affected by damage to the axle. For example, if the axle spindle is bent, this will usually cause a negative camber on that side which will cause excess tread wear on the inside of that tire.

How does the weight distribution affect the performance of beam axles?

The weight distribution significantly impacts the performance of vehicles equipped with beam axles, and it plays a crucial role in determining their stability and handling characteristics. Here’s how weight distribution affects the performance of beam axles:

1. Balance and Stability:

The even distribution of weight among the vehicle’s axles is essential for maintaining balance and stability. When the weight is evenly distributed, the vehicle is less likely to experience weight shifts that can lead to instability or loss of control, especially during cornering and sudden maneuvers.

2. Oversteer and Understeer:

Weight distribution affects a vehicle’s tendency to oversteer or understeer. Oversteer occurs when the rear of the vehicle loses traction and swings outward during a turn, potentially leading to a loss of control. Understeer happens when the front tires lose traction, causing the vehicle to plow straight ahead rather than following the intended path. Proper weight distribution minimizes the risk of oversteer or understeer, contributing to predictable and safe handling.

3. Traction and Grip:

Weight distribution influences the amount of weight pressing down on each tire. Adequate weight on each tire enhances traction and grip, especially when driving on slippery or uneven surfaces. When too much weight is concentrated on a single axle, it can lead to wheel spin and reduced traction, affecting the vehicle’s performance off-road or in adverse weather conditions.

4. Load-Carrying Capacity:

For vehicles designed to carry heavy loads or passengers, proper weight distribution is critical to ensure that the suspension and beam axles can support the weight without strain. An imbalanced load can lead to premature wear and tear on suspension components, reducing the vehicle’s load-carrying capacity and potentially compromising safety.

5. Maneuverability:

Well-balanced weight distribution improves a vehicle’s maneuverability. It makes the vehicle more responsive to steering inputs, facilitating smoother and more controlled handling. This is particularly important for commercial and utility vehicles that need to navigate through tight spaces or make precise movements.

6. Tire Wear:

Uneven weight distribution can result in uneven tire wear. When one set of tires carries a significantly higher load than the others, those tires may wear out faster, leading to the need for premature replacement. Proper weight distribution helps ensure even tire wear and extends the lifespan of the tires.

Summary:

Weight distribution is a critical factor in optimizing the performance of vehicles equipped with beam axles. Properly balanced weight contributes to stability, predictable handling, enhanced traction, and increased load-carrying capacity. It ensures that the beam axles and suspension components operate efficiently, promoting the vehicle’s safety and overall performance.

What is the history of beam axles in automotive engineering?

The history of beam axles in automotive engineering is rich and spans several decades. Beam axles, also known as solid axles or live axles, have played a crucial role in the development of vehicles. Here’s a brief overview of their history:

Early Automobiles:

When automobiles were first introduced in the late 19th and early 20th centuries, they primarily used beam axles due to their simplicity and reliability. These axles provided a solid platform for mounting the wheels and supporting the vehicle’s weight. Early cars often featured front and rear beam axles connected by leaf springs for a smoother ride.

1920s and 1930s:

During the 1920s and 1930s, beam axles were prevalent in the automotive industry. They were commonly found in both passenger cars and commercial vehicles. The Ford Model T, for example, used beam axles and was one of the most iconic vehicles of that era.

Evolution and Diversification:

As automotive engineering progressed, there was a diversification of suspension systems. While beam axles remained a staple in many vehicles, independent suspension systems began to gain popularity for their improved ride comfort and handling characteristics. Independent front suspension systems, which allowed each wheel to move independently, became a common feature in passenger cars, while beam axles remained popular in trucks and heavy-duty applications due to their load-bearing capacity.

Post-World War II Era:

After World War II, there was a shift toward more advanced suspension systems. Passenger cars increasingly adopted independent suspension, offering a smoother and more comfortable ride. However, beam axles continued to be used in the rear of many vehicles, especially trucks and SUVs, where load-bearing capability and durability were key considerations.

Specialized Applications:

Beam axles found new life in off-road vehicles and heavy-duty trucks, where their durability and ability to handle rough terrain made them ideal choices. In the world of off-roading and 4×4 vehicles, solid axles (a type of beam axle) were preferred for their ruggedness and articulation capabilities.

Modern Use:

Today, beam axles are still used in specific vehicle applications, primarily in the rear suspension of trucks and heavy-duty commercial vehicles. Their load-bearing capacity and durability make them well-suited for these demanding roles. Additionally, some retro-style and classic vehicles may incorporate beam axles to capture the aesthetics and character of older vehicle designs.

In summary, the history of beam axles in automotive engineering is marked by their enduring presence in various vehicle types. While independent suspension systems have gained ground in passenger cars, beam axles continue to thrive in specialized applications, ensuring their relevance in modern automotive design.

What is a beam axle, and how does it differ from independent suspension?

A beam axle, also known as a solid axle or live axle, is a type of suspension system used in vehicles. It differs from independent suspension in several ways:

Beam Axle:

  • A beam axle consists of a single solid beam (shaft) that spans the width of the vehicle and connects both wheels on the same axle. It is a single rigid unit.
  • Beam axles are commonly found in older vehicles and some heavy-duty trucks and off-road vehicles.
  • When one wheel encounters a bump or obstacle, the other wheel on the same axle is affected. This can result in a less comfortable ride and reduced traction for both wheels.
  • Beam axles are generally more robust and suitable for heavy loads, making them preferred in certain commercial and industrial applications.
  • They are relatively simple in design and tend to be more cost-effective to manufacture and maintain.

Independent Suspension:

  • Independent suspension, on the other hand, allows each wheel to move independently of the other. It consists of separate suspension units for each wheel.
  • Independent suspension is commonly used in modern passenger cars, SUVs, and performance vehicles.
  • Each wheel responds individually to road imperfections, providing a smoother and more comfortable ride. It also improves traction, handling, and stability.
  • Independent suspension is generally lighter and offers better handling characteristics, making it suitable for most everyday driving situations.
  • However, it can be more complex and costly to manufacture and maintain compared to beam axles.

While beam axles are known for their strength and simplicity, independent suspension systems are favored for their superior ride comfort, handling, and adaptability to various road conditions. The choice between the two depends on the vehicle’s intended use, design goals, and the trade-off between load-carrying capacity and ride quality.
