The transfer case of the paver is the core transmission component of the paver, responsible for distributing engine power to devices such as the walking system, conveyor system, and screed plates. Adopting a gear transmission structure, it has multi gear output and variable speed ratio adjustment function. Modern transfer cases are made of high-strength alloy materials, equipped with electro-hydraulic control systems and forced lubrication devices, and have a transmission efficiency of over 95%. Daily attention should be paid to oil level inspection and regular oil change maintenance. Common faults include oil leakage, abnormal noise, and overheating. With the advancement of technology, intelligent monitoring and efficient transmission have become development trends.
