The shift hand ball is usually located below the steering wheel in the cab and is used to connect the gear lever and the driver's hand operation. Its main function is to control the vehicle's gear shifting operation and realize the driver's intention to transmit power to the wheels.

Specifically, the role of the shift ball in FAW Jiefang trucks is mainly reflected in the following aspects:

1. Control shifting: The driver can move the vehicle forward, backward, accelerate, decelerate, etc. by operating the shift ball. This is one of the most basic and frequent operations during driving.
2. Transmit driving intention: The shift ball accurately transmits the driver's intention to the vehicle's transmission system, allowing the vehicle to drive according to the driver's wishes.
3. Ensure driving safety: In heavy vehicles such as FAW Jiefang trucks, the stability and accuracy of the shift ball are crucial to driving safety. Smooth shifting operations can ensure the stability and safety of the vehicle during driving.
4. Improve driving experience: The high-quality shift ball design can provide the driver with a good feel, reduce fatigue caused by long-term driving, and thus improve driving comfort and pleasure.
