The steering wheel and differential wheel of AGV (Automated Guided Vehicle) are two different driving methods, which have significant differences in structure, working principle, and application characteristics:
AGV steering wheel:
1. Structure:
The steering wheel usually includes one or more integrated drive motors, steering motors, reducers, encoders, and other components, which are directly installed on the steering shaft of the AGV body. Each steering wheel can independently control the direction and speed of rotation, achieving all-round and arbitrary angle steering.
2. Working principle:
The steering wheel independently controls the rotation direction and speed of each wheel, enabling the vehicle to move in all directions. For example, when two steering wheels rotate in the same direction and at the same speed, the AGV moves forward in a straight line; When two steering wheels rotate at different speeds or in opposite directions, AGVs can achieve complex movements such as turning in place, lateral displacement, and oblique movement.
3. Application features:
The steering wheel system provides high flexibility and can achieve precise positioning, small turning radius, omnidirectional movement and other characteristics, especially suitable for scenarios with limited space, frequent direction changes or precise docking, such as warehousing logistics, precision assembly, etc.
Differential wheel:
1. Structure: The differential wheel usually refers to a system composed of two or more ordinary drive wheels (non omnidirectional drive), which adjust the speed difference between the left and right wheels through the differential to achieve vehicle turning. The differential wheel system does not include an independent steering motor, and steering depends on the speed difference between the wheels.
2. Working principle:
When driving in a straight line, the wheels on both sides of the differential wheel rotate at the same speed; When turning, the speed of the inner wheel slows down and the speed of the outer wheel increases, using the speed difference to make the vehicle turn smoothly. Differential wheels are usually paired with fixed front or rear wheels as guide wheels to complete steering together.
3. Application features:
The differential wheel system has a relatively simple structure, low cost, convenient maintenance, and is suitable for scenarios that are cost sensitive, have low space requirements, and have relatively conventional steering requirements, such as outdoor inspections and material handling. However, due to its large turning radius, its flexibility and positioning accuracy are relatively low.
In summary, the main difference between AGV steering wheel and differential wheel is:
• Steering method:
The steering wheel achieves all-round steering by independently controlling each wheel, while the differential wheel relies on the speed difference between the wheels for turning.
• Flexibility:
The steering wheel system has higher flexibility and can achieve omnidirectional movement, small turning radius, precise positioning, etc., while the differential wheel system has relatively limited turning ability and a larger turning radius.
Application scenarios:
The steering wheel is suitable for situations that require high space utilization, flexibility, and positioning accuracy, such as warehousing logistics, precision assembly, etc; Differential wheels are more suitable for scenarios that are cost sensitive, have low space requirements, and have relatively conventional steering requirements, such as outdoor inspections and material handling.
