The axle belongs to the walking mechanism of a vehicle and bears functions such as loading, driving, and braking. Vehicle axles can be divided into many types, such as integral and disconnected axles according to structure, drive axle, steering axle, drive steering axle, and support axle according to function, drum axle and disc axle according to braking method, and low flat axle, three line six axle axle, etc. according to applicable vehicle models.

Today, Darong Axle is going to introduce an eccentric axle to everyone. This eccentric axle belongs to the driven support axle and is commonly used on sedans.

As the name suggests, an eccentric axle refers to an axle where the axle beam and hub center are not in the same straight line, as shown in the following figure:

Unlike ordinary axles, the eccentric axle beam is designed with a structure similar to a "Z" shape at both ends, so that the axle head and axle beam are located on two different horizontal lines, giving the overall appearance of a "door" shape.

Speaking of this, I have to mention the gantry axle. The portal axle is a variant of the wheel side bridge, which is specially designed for the extreme environment in the wild. The extremely high chassis can help vehicles to climb mountains and pass through forests. It is generally used on combat vehicles and some off-road vehicles. Its design and structure are more complex than the eccentric axle.

From a simple appearance perspective, a gantry axle is very similar to an eccentric axle. However, in reality, the application methods of an eccentric axle and a gantry axle are completely opposite. The gantry axle belongs to a positive "door" type installation, while the eccentric axle belongs to an inverted "door" type installation; The application of a gantry axle is to improve the vehicle chassis, while an eccentric axle is to reduce the chassis height of a car carrier.

We all know that sedan transport vehicles are specifically used for transporting goods, exhibition vehicles, or experimental vehicles. The models include sedans, business vehicles, vans, jeeps, and so on. Whether it is purchasing cars from different places, using cars from different places, or transporting vehicles during travel, they can all be achieved through sedan transport vehicles.

For sedan transport vehicles, the level of their operating income is directly linked to the number of vehicles loaded. In order to earn more freight, illegal modifications have emerged one after another, such as the common illegal behaviors of "big monsters", "second monsters", "airplane boards", "double row cars", which have had a great negative impact on traffic safety.

After the intervention of relevant departments, the car transportation industry has gradually become standardized, and the overall freight environment continues to be sluggish, with freight rates only falling but not rising. How to earn more profits within the legal scope has become a key concern for car owners. The emergence of eccentric axles has to some extent given car owners such a possibility.

1. More loading space.

Eccentric bridges can further lower the vehicle chassis, allowing for two rows of loading without exceeding the height limit. Coupled with the inclined placement of goods, it can greatly improve space utilization.

2. The center of gravity is lower and smoother.

The lower chassis of the vehicle makes it smoother to run, with a smaller and more flexible turning radius, which can improve the towing capacity of the main vehicle and further provide the possibility of loading more goods.

3. Stable transportation is beneficial for speed increase

After lowering the chassis of a car, it can improve the grip of the tires, which has a certain helping effect on the vehicle's starting and acceleration. At the same time, a lower chassis can further reduce wind resistance, reduce power loss, and fully utilize the vehicle's performance.

4. Loading and unloading are more convenient.

When loading and unloading goods, the car mainly relies on the control of the hydraulic system. After the chassis of the vehicle is lowered, the loading and unloading of goods on the platform is more convenient and efficient.

5. Strong passability on restricted height sections.

The chassis of the vehicle has been lowered, and the overall height of the vehicle can also be reduced to a certain extent, improving the passing ability of the vehicle on the height limited road section.

The eccentric axles produced by Darong Group are all made of 20Mn2 high-strength seamless steel pipes as raw materials, which have undergone 15 production processes such as heat quenching and tempering treatment, sandblasting and rust removal, multi-point straightening, intermediate frequency induction strengthening of shaft heads, machine manual welding, as well as quality inspection processes such as salt spray testing, magnetic particle testing, and one million fatigue tests. The 19mm thick axle φ The 127 circular shaft, paired with dedicated wheel end components for car transportation, can fully meet the actual transportation needs of the car. The rated load tonnage and wheelbase parameters can be customized.

Of course, the application of eccentric axles is not limited to sedan vehicles, and other models with good transportation conditions, low requirements for vehicle chassis height, or pursuit of low center of gravity can also be applied.
