13t semi-trailer rear axle modified 16t brake?

The rear axle is one of the key load-bearing components on the semi-trailer, and it is also closely related to the braking performance of the vehicle. In general, the wheel end components of trailer axles of different tonnages are also different. But in practical applications, we often hear that "13t axles are converted to 16t brakes", how to understand this?

In fact, the so-called "refitting 13t axles with 16t brakes" refers to refitting the original brakes on the rear axle of a 13t semi-trailer into specifications for 16t axles. In layman's terms, 16t brake pads and brake drums are installed on the 13t rear axle.

This kind of modification is relatively common in the industry. In order to pursue better braking effect, many car owners will directly propose to use 16t brakes when buying a trailer or choosing a trailer axle, and some car owners choose to modify it later by themselves.

Some car owners said: Is it enough to install the 16t brake pads or brake drums on the 13t axle? It's not that simple.

For the rear axle of a semi-trailer, the parts specifications of 13t and 16t are not the same. The brake pads of 13t are not as wide as 16t, and the wheel hub is not as big as 16t. In addition, the inner and outer gears of the bearing are the same size as 13t, the inner gear of 16t is larger, and the outer gear is smaller.

The existence of these differences requires the owner to use special brake pads or brake drums when refitting. Generally, eccentric brake shoes or special brake drums are commonly used. Otherwise, problems such as brake pad bumping against the drum under non-braking conditions and eccentric wear of the brake pads will easily occur. Therefore, refitting the brake also needs to be handed over to a special axle factory or repair shop.

Some car owners also pointed out that although the brake pads and brake drums of the refitted trailer axles are thicker and wider, if the modification is not good, it will easily cause the problem of uneven center of gravity during braking, which is very wear-resistant, especially after switching to partial hoofs, the braking effect is even worse than the original 13t brakes. Besides, the brake pads and brake drums of a semi-trailer are modified, and the cost will be several thousand. It is better to directly choose the original 16t axle, or choose a brake valve with better performance.

Besides, there are many axle brands on the market at present, including many products with reliable quality and affordable price. Instead of choosing to modify, it is better to directly choose the original axle.

The rear axle of the DARO16t semi-trailer is made of 20Mn2 high-strength steel, which is formed by one-piece hot rolling, which avoids the problems of strength reduction caused by welding, and does not deform or bend under high-strength transportation. The American 16t has high cost performance, good heavy-duty performance, universal accessories, and convenient maintenance; the German 16t is long-lasting and stable, with reduced self-weight and improved heat dissipation performance, making it more suitable for long-distance transport vehicles.
