Embodiment Construction

[0043] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and together with the embodiments of the present invention are used to explain the principle of the present invention and are not intended to limit the scope of the present invention.

[0044] The unmanned vehicle steering system based on the two-stage planetary steering machine is usually used to realize the switching of the two-stage planetary steering machine in different states. The main principle is to drive the front longitudinal tie rod of the planetary steering machine to translate and / or rotate through the swing of the joystick. , so as to realize the translation of the steering trailing rod, so that the gear set of the two-stage planetary steering machine can realize clutching. It should be noted that the two-stage planetary steering gear is usually used in the stee...

Abstract

The invention relates to an unmanned vehicle steering system and method based on a secondary planetary steering gear, belongs to the technical field of unmanned vehicle steering, and solves the problems of low control accuracy and low response speed of an executing mechanism in traditional vehicle unmanned control are solved. According to the unmanned vehicle steering system based on the secondaryplanetary steering gear, reciprocating motions of a hydraulic cylinder and a steering operating lever are controlled by using an electro-hydraulic servo valve so that a vehicle is driven to steer; and meanwhile, switching between manual operation and electric control operation can be realized; the mechanism is simple and feasible; the machining and mounting are convenient; and the unmanned vehicle steering system based on the secondary planetary steering gear is suitable for severe working environments of tracked vehicles.

Description

technical field [0001] The invention relates to the technical field of unmanned vehicle steering, in particular to an unmanned vehicle steering system and method based on a two-stage planetary steering machine. Background technique [0002] The electro-hydraulic servo control system is a control system widely used in various fields of the national economy. The output can automatically, quickly and accurately change with the change of the input, and the output power can be greatly amplified. Compared with ordinary hydraulic or pneumatic control systems, it has the advantages of fast response, high load stiffness, high energy density, and flexible signal processing. It is widely used in machining, engineering machinery, automobiles, ships and other industries. [0003] Controlling the servo hydraulic cylinder through the electro-hydraulic servo valve is the most common electro-hydraulic servo control system, and the response speed and control accuracy of the electro-hydraulic ...
