Abstract

The invention provides a differential assisted hydraulic steer-by-wire method of an all-wheel independent electrically driven articulated vehicle, and belongs to the technical field of engineering machinery. The articulated vehicle structurally and mainly comprises a front vehicle body, a rear vehicle body, an articulated body, independent electrically driven wheels, controllers, a drive-by-wire articulated hydraulic steering system, a main controller, a steering wheel system and the like, wherein the main controller is an upper controller of the complete vehicle and receives steering signals of the steering wheel system, and the front vehicle body and the rear vehicle body rotate by controlling the articulated hydraulic steering system and all the electrically driven wheels to act so as to achieve steering. The method is based on the controllable articulated vehicle all-wheel independent drive, and the problems that the response speed is low, the steering angle is limited by a steering structure, tyres are seriously abraded and the steering energy consumption is high in existing articulated hydraulic steering modes are solved through the cooperation of differential steering and hydraulic steer-by-wire steering.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a differential auxiliary wire-controlled hydraulic steering method for an all-wheel independent electric drive articulated vehicle. Background technique [0002] Articulated engineering vehicle is a kind of engineering machinery equipment suitable for working in harsh environments. It can realize flexible steering through the rotation of the front and rear car bodies, and has strong passability. New multi-axle articulated engineering vehicles, such as six-wheel AC drive articulated dump truck, each wheel is driven by an independent motor, and the steering method is articulated hydraulic steering. However, analyzing the characteristics of its steering structure, it can be seen that there are still some problems in the steering process of the articulated hydraulic steering mechanism, which mainly include the following aspects. One: due to the response delay of the hyd...
