Embodiment Construction

[0038] The preferred embodiments of the present invention are specifically described below with reference to the accompanying drawings, wherein the accompanying drawings constitute a part of the present application, and together with the embodiments of the present invention, are used to explain the principles of the present invention, but are not used to limit the scope of the present invention.

[0039] The unmanned vehicle steering system based on the secondary planetary steering machine is usually used to realize the switching of the secondary planetary steering machine in different states. The main principle is to drive the connecting rod system of the planetary steering machine to drive the actions of different actuators of the secondary planetary steering machine. . In general, the connecting rod drive system drives the translation and / or rotation of the front longitudinal tie rod of the planetary steering machine, thereby realizing the translation and / or rotation of the ...

Abstract

The invention relates to a manual-autonomous-integrated automatic steering system and method based on a two-stage planetary steering machine, belonging to the technical field of steering of unmanned tracked vehicles. The invention controls the hydraulic cylinder connected in parallel in the connecting rod system through the electro-hydraulic proportional valve with servo function, drives the action of the two-stage planetary steering gear, and then realizes the control of the vehicle steering; the application of the proportional valve reduces the impact on the oil. Accuracy requirements; the application of hydraulic control system to achieve rapid switching between automatic driving and manual driving; the addition of manual driving assistance functions; at the same time, it also retains a complete emergency mechanical manipulation function to ensure that the vehicle can be driven manually in the event of a hydraulic system failure Take control. The invention has the advantages of simple and feasible mechanism, convenient processing and installation, and is suitable for the harsh environment of the tracked vehicle.

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 unmanned vehicle steering system based on the secondary planetary steering machine is usually used to realize the switching of the secondary planetary steering machine in different states. The main principle is to drive the connecting rod system of the planetary steering machine to drive the actions of different actuators of the secondary planetary steering machine. . In general, the connecting rod drive system drives the translation and / or rotation of the front longitudinal tie rod of the planetary steering machine, thereby realizing the translation and / or rotation of the rear longitudinal tie rod, which in turn drives the rotation of the dispatching plate, thereby making the secondary planetary steering machine operate. The brake o...
