What is unique about the truck shift knob in design and function?

The uniqueness of the truck shift knob in design and function is mainly reflected in the following aspects:
1. Uniqueness in design
Small size: The knob-type shift mechanism is designed to be very small, usually located between the main and co-driver or on the center console. This design not only saves space in the cab, but also makes the overall layout more concise and beautiful.
Easy to operate: The operation of the knob-type shift mechanism is very simple. The driver only needs to gently rotate the knob to achieve the shift, without pushing, pulling or toggling like the traditional shift lever. This design allows the driver to shift gears more conveniently during driving, improving driving comfort and safety.
Clear and intuitive: The design of the knob-type shift mechanism is clear and intuitive, and the gear position is clearly marked. The driver can understand the current gear position at a glance, reducing safety hazards caused by misoperation.
2. Uniqueness in function
Automatic return torque: Some knob-type shift mechanisms have an automatic return torque function. This design can effectively prevent the vehicle from switching to the wrong gear due to accidental contact, improving driving safety.
Multiple gear modes: Knob-type shift mechanisms usually provide multiple gear modes, such as R reverse gear, N neutral gear, D forward gear, etc., to meet the needs of different driving scenarios. In addition, some high-end models are also equipped with special gear modes such as creep gear (L gear) to adapt to more complex road conditions.
Economic and power mode switching: Some knob-type shift mechanisms also support switching between economic mode and power mode. In economic mode, the vehicle will limit the output power of the motor to save power; while in power mode, the vehicle will provide more abundant power output to meet the driver's driving needs.
Fixed gear function: Some knob-type shift mechanisms also have a fixed gear function, such as the "L" function key on the Jiefang J7 heavy truck. On long downhill sections, the driver can fix the gear in a certain gear range so that the engine cylinder brake can achieve the max braking effect, thereby ensuring the safe driving of the vehicle.
In summary, the truck shift knob has many unique features in design and function, which make the knob-type shift mechanism widely used in the truck field.
