  • AGV小車轉向裝置 AGV Trolley Steering Device

    AGV小車常設計成三種運動方式:只能向前;能向前與向后;能縱向、橫向、斜向及回轉全方位運動。

    AGV are often designed in three motion modes: only forward; forward and backward; longitudinal, lateral, oblique and rotary motion in all directions.

    轉向裝置的結構也有三種:

    There are also three types of steering gear structures:

    (1) 鉸軸轉向式三輪車型。

     車體的前部為一個鉸軸轉向車輪,同時也是驅動輪。轉向和驅動分別由兩個不同的電動機帶動,車體后部為兩個自由輪,由前輪控制轉向實現單方向向前行駛。其結構簡單、成本低,但定位精度較低。

    (1) Articulated axle steering three-wheeled models

    The front part of the car body is a hinged steering wheel, which is also the driving wheel. Steering and driving are driven by two different electric motors respectively. The rear of the car body is two free wheels, and the steering is controlled by the front wheels to achieve forward driving in one direction. The structure is simple and the cost is low, but the positioning accuracy is low.

    (2) 差速轉向式四輪車型。 

    車體的中部有兩個驅動輪,由兩個電機分別驅動。前后部各有一個轉向輪(自由輪)。通過控制中部兩個輪的速度比可實現車體的轉向,并實現前后雙向行駛和轉向。這種方式結構簡單,定位精度較高。

    (2) Differential steering four-wheeled models

    There are two driving wheels in the middle of the car body, which are driven by two motors respectively. There is a steering wheel (free wheel) at the front and rear. By controlling the speed ratio of the two wheels in the middle, the steering of the car body can be realized, and the front and rear bidirectional driving and steering can be realized. This method has a simple structure and high positioning accuracy.

    (3)全輪轉向式四輪車型。 

    車體的前后部各有兩個驅動和轉向一體化車輪,每個車輪分別由各自的電動機驅動,可實現沿縱向、橫向、斜向和回轉方向任意路線行走,控制較復雜。

    (3) All-wheel steering four-wheel models

    There are two integrated driving and steering wheels at the front and rear of the car body, each wheel is driven by its own electric motor, which can walk along any route in the longitudinal, lateral, oblique and turning directions, and the control is more complicated.
