What is a car transfer case?

The transfer case is an important automotive component. Its main function is to distribute the power of the engine, enabling the power to be transmitted to the rear axle or to both the front axle and the rear axle simultaneously. This device is particularly important in four-wheel drive vehicles because it can distribute power to different wheels as needed, thereby enhancing the vehicle's handling and stability.

With the continuous development of four-wheel drive technology, the design of transfer cases is also constantly improving. The transfer cases in modern automobiles are already equipped with multiple functions and can be intelligently adjusted according to driving needs and road conditions to provide the best power distribution plan. For instance, when driving off-road, the transfer case can transfer more power to the rear axle to enhance the vehicle's traction. When driving in the city, it can evenly distribute power to the front and rear axles to enhance the vehicle's flexibility and handling.

Different types of four-wheel drive vehicles may be equipped with different types of transfer cases. These transfer cases vary in structure and function to meet various driving requirements. For instance, some transfer cases have a locking function that can fix the power of the front and rear axles in a certain proportion. Some transfer cases, however, have an automatic mode that can automatically adjust the power distribution based on the vehicle's driving status and road conditions.
