Industrial joystick controller is one of the main control spare parts of construction machinery, which is mainly installed on the operating panel of the equipment or the armrest of the driver’s seat. The main function is to operate mechanical equipment forward, backward, turning, lifting and other functions.

Joysticks can be classified according to their functions:

● From the joystick structure can be divided into single axis joystick, double axis joystick, three axis joystick.

● From the reset mode can be divided into Frühlingsrückkehr joystick, friction positioning joystick, gear handle controller.

● From the operation mode can be divided into: fingertip type joystick and hand type joystick.

The following is a simple analysis of the basic structure of the joystick – the universal ball structure:

The universal ball mainly changes the Angle of the transmission shaft by external force, and realizes the linear electrical signal output by Hall effect so as to realize the operation function of the handle.

Structural advantages: compact structure, less spare parts, safe and reliable; Rich in structural changes; Stable structure, suitable for mass production, low risk of failure.

Structural shortcomings: ball structure processing cost is high, production processing has a certain degree of difficulty. In recent years, with the gradual development and improvement of processing equipment, process and technology, the impact of this problem on products is gradually weakening.

With the continuous development of technology, the gimbal structure will gradually improve and get better application.
