What is bogie suspension in trucks?
Truck bogie suspension refers to a suspension system commonly used in heavy vehicles such as trucks and trailers.
It consists of a set of two or more axles connected to the frame or chassis through a system of springs, shock absorbers and linkages.
The main purpose of bogie suspension is to evenly distribute the weight of the vehicle and its cargo over multiple axles, thereby reducing the effects of road irregularities and providing a smoother ride.
A bogie suspension system is particularly beneficial for trucks that need to carry heavy loads over long distances because it helps improve stability, traction, and overall handling.
By spreading weight across multiple axles, bogie suspension also helps minimize wear and tear on individual components, thereby reducing maintenance costs and extending the life of the vehicle.
Additionally, bogie suspension is designed to adapt to different types of terrain and road conditions, making it a versatile option for trucks that need to operate in different environments.
This type of suspension system comes in a variety of configurations, including leaf spring, air suspension and coil spring setups, each offering unique advantages in terms of load capacity, ride comfort and adjustability.
Overall, bogie suspension plays a vital role in improving the performance and durability of trucks, making it an important feature for commercial vehicles that need to transport heavy loads safely and efficiently.
Applications
Bogie suspension is to reduce the common leaf spring suspension's front and rear brackets into a single bracket connected to the chassis body.
Its stress points are shared on the front and rear axles. Compared with ordinary leaf spring suspensions, bogie suspensions can carry more capacity.
This kind of Bogie suspension is less used in ordinary semi-trailers, and is mainly used in heavy semi trailer and truck.
The bogie leaf spring is use for bogie suspension, there are three types of leaf spring design:
1. 12T leaf spring (section:90×13, 90×16, 90×18, 18 leaves) for 24T bogie;
2. 14T leaf spring (section: 120×14, 120×16, 19 leaves) for 28T bogie;
3. 16T leaf spring (section: 120×14, 120×18, 120×20, 17 leaves) for 32T bogie.
What is the difference between axle and bogie?
Axles and bogies are both components of a vehicle's suspension and drivetrain, but they serve different purposes and have different characteristics.
The axle is the central shaft that rotates with the wheels and is responsible for transmitting the engine's power to the wheels.
In most vehicles, the axle is a single straight shaft that connects the wheels on either side of the vehicle. It plays a vital role in supporting the weight of the vehicle and its cargo, as well as providing the torque needed to propel the vehicle forward or reverse.
Axles are found in both front-wheel drive and rear-wheel drive vehicles, and they are often equipped with differential gears to allow the wheels to spin at different speeds when cornering.
A bogie, on the other hand, refers to a set of two or more axles connected to the frame or chassis through a system of springs, shock absorbers, and linkages.
Unlike a single axle, bogies are designed to distribute the weight of a vehicle and its load over multiple axles, thereby increasing stability, load-carrying capacity and overall performance.
Bogies are typically used in heavy-duty vehicles such as trucks, trailers and rolling stock, where the ability to carry heavy loads over long distances is critical.
One of the main differences between axles and bogies is their respective roles in supporting and distributing weight.
While axles are primarily used to transmit power and support the weight of a single wheel or pair of wheels, bogies are designed to distribute the weight of a vehicle and its cargo over multiple axles, reducing the impact of road irregularities and providing a better ride Smoother.
In addition, bogies are often equipped with additional components such as suspension systems and connecting rods to further enhance their load-bearing capacity and overall performance.
In summary, the main difference between axles and bogies is their design and functionality.
An axle is a single shaft that transmits power to the wheels, while a bogie is a set of multiple axles that work together to distribute weight and improve the performance of a heavy vehicle.
These two components are critical to the proper functioning of the vehicle's suspension and drivetrain, but they serve different purposes and are designed to meet different operating requirements.
