The difference in wheelbase length of semi-trailer

An axle is a cylinder on a vehicle where two wheels are attached to hold the weight of the vehicle. Each pair of left and right wheels is connected by an axle. Here's a simple example:

Above, for example, is a relatively simple axle. Of course, the axle of the semi trailer is much more complex in structure, and is generally installed and used in the way of the axle assembly. Axle assembly not only needs to bear the weight of the body, but also needs to bear the function of braking and maintaining the vehicle running, so its performance is particularly important for driving safety.


Now that you know what an axle is, the wheelbase is easier to understand.


The semi-trailer wheelbase refers to the distance from the center of the front axle to the center of the rear axle, through the same side of the vehicle adjacent to two wheel centers, and perpendicular to the longitudinal plane of symmetry of the vehicle between two vertical lines.

Semi-trailer wheelbase can be divided into fixed wheelbase, bogie wheelbase and full wheelbase:


1. Fixed wheelbase refers to the horizontal distance between the center lines of the front and rear axles at both ends of the main frame of the trolley type vehicle. In order to facilitate passing the curve, fixed wheelbase should not be too long.


2. The bogie wheelbase refers to the distance between the center line of the axle at both ends of a bogie.


3. The full wheelbase refers to the horizontal distance between the center lines of the front and rear ends of the vehicle axles, that is, the distance from the front axle to the last axle, which is the main parameter affecting the "turntable length" of the train.

What's the difference in wheelbase length for a semi trailer?


1. Long wheelbase


(1) Advantages:


The longer the wheelbase, the larger the turning radius, the more stable the vehicle driving;


The longer the length of the semi-trailer, the more convenient the transport of larger types of goods;


The riding space can be expanded to a certain extent, and the comfort can generally be improved.


(2) Disadvantages:


The longer the wheelbase, the less flexible the vehicle turns;


Although the ride space is comfortable, but the control is poor, the safety factor is reduced;


More parking space is required, and a long wheelbase means more parking space.


3. Short wheelbase


(1) Advantages:


The wheelbase is short, the vehicle is more flexible, and it is more convenient to enter and exit the curve or park in the parking space.


Short wheelbase good movement, strong control.


(2) Disadvantages:


Poor stability at high speed;


Transport of goods is restricted.


Semi-trailer, as the most widely used vehicle in the transportation industry, plays a very important role, which requires that the axle quality of semi-trailer must be strictly passed. Especially under the premise of the prevailing trend of lightweight, it is necessary not to blindly sacrifice the bearing performance of the axle itself in order to achieve the purpose of weight reduction. Otherwise, once the axle breaks in the process of full load, the consequences will be unimaginable. Owners in the purchase of axles, especially lightweight axles, must choose regular manufacturers, must not believe the publicity stunt of three products.

DARO Heavy Industry Group is one of the earliest trailer axle enterprises in China, and also the earliest trailer axle enterprise in Liangshan mass production of integrated shaft body. Through independent innovation, the development of new appearance, new technology, new technology, overcome the problem of lightweight, while reducing the weight, the bearing capacity does not decrease but increase, fully meet the needs of owners. All the axles produced by DARO Group have gone through 15 precise and rigorous production processes, and the reliable quality has been consistent for decades. In terms of price, Daro always insists on giving back to users with the most reasonable price, and has won a good reputation among users with its ultra-high cost performance.
