What is a trailer cooling hole axle and the role of cooling hole axle

The trailer cooling hole is usually arranged between the wheel hub body and the flange. The design of the trailer axle wheel hub vlents is mainly to enhance the heat dissipation performance of the wheel hub, reduce the temperature generated by the brake drum and brake pads, and ensure the safety and stability of the vehicle during driving.

Working principle of cooling hole:

Due to the wind speed difference inside and outside the trailer cooling hole, heat convection is formed, and the brake drum can be forced to be air-cooled, so that the brake drum will not overheat, which can ensure the normal operation of the brake drum and ensure driving safety, and no high-level water tank is required for water cooling.

Role of vlents:

Heat dissipation and cooling: The cooling hole can increase the heat dissipation surface area of the wheel hub and make the air circulation smoother. When the vehicle is driving, the airflow generated by the vlents helps the brake drum and brake pads to quickly dissipate heat and reduce the temperature. This is of great significance to prevent the wheel hub. Brake drum and brake pad overheating, protect the brake system, and extend the service life of the wheel hub brake drum and brake pad.

Reduce weight: The design of the cooling hole can also reduce the weight of the wheel hub to a certain extent, thereby saving production costs, reducing the total weight of the axle, and improving the fuel economy and handling of the vehicle.

LUEN is one of the few manufacturers of cooling hole axles in China, and is very popular in Latin American countries such as Ecuador, Peru, Bolivia, and Colombia.
