What are the characteristics of transfer cart steering system
2017-12-27
The most striking feature of the switch to electric transfer cart is the shift to flexibility, and why is it so good to turn around?What are the reasons for this?Then the hydraulic steering electric transfer cart manufacturer Henan PERFECT Handling Equipment Co.,Ltd. will share the content with you.
The normal steering mode turns when the center wheel is not deflected, the front and rear wheels are reversed, and the center axis is on the central axis.The steering wheel is not deflected by the steering wheel, the front and the center wheel are deflected, and the center is on the back axis.
The center rotation is not deflected by the rotation of the center wheel, and the reverse deflection of the front and rear wheels is the same, and the center of the rotary center is in line with the center of electric plane.Three other modes of work;Straight line, transverse and oblique lifting transfer cart of electrohydraulic proportional steering system optimization simulation of steering and driving mode of steering system of transfer cart car by steering trapezoidal mechanism is unable to achieve various functions, n wheelset must have independent steering system, the rotation of the wheels independently according to the requirements of design.
The steering system consists of drive rod mechanism, hydraulic system and electric control system.
The control system consists of rotary encoder, PLC controller and rotary potentiometer.The rotary encoder is connected directly to the steering wheel, transmitting the driver's steering signal to the PLC controller;The rotating potentiometer directly measures the Angle of the wheel and inputs it into the PLC controller as the feedback signal.The PLC controller outputs the control signal according to the preset control program, controls the opening and oil flow direction of the proportional valve, thus controlling the retractable position of the steering cylinder and the speed of the piston movement.
Single wheel steering control system principle.The electro-hydraulic proportional steering system adopts the closed-loop control system and the system output is controlled by the input of the system.Therefore, the electric platform car system has the ability to automatically correct the deviation and obtain a fairly high control precision.
