Problems solved by technology

However, the existing articulated body has disadvantages such as complex structure, poor stability, and the inability to ensure an accurate steering path when turning.
In addition, in the fields of live broadcasting and plant protection, the existing articulated body is not purely electric drive control, and it is difficult to realize automatic driving or remote control

Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] Such as figure 1 with figure 2 As shown, the articulated four-wheel drive chassis of this embodiment includes an articulated vehicle frame 1 hinged by two brackets 11, and each bracket 11 is equipped with two traveling wheels 2 driven by an independent rotary drive device. Four traveling wheels 2 on the two supports 11 are located in the same plane, and the hinge axes of the two supports 11 coincide with two diagonal intersections of a hypothetical rectangle, and the four traveling wheels 2 on the two supports 11 are respectively arranged correspondingly On the four corners of the hypothetical rectangle, the axes of rotation of the two traveling wheels 2 on the same support 11 are collinear, and the four traveling wheels 2 are located in the same plane and are parallel to each other. The steering drive assembly that the brac...

Abstract

The invention discloses a steering method for an articulated four-wheel-drive chassis. The articulated four-wheel-drive chassis includes an articulated frame formed by two brackets. Walking wheels, the four walking wheels on the two supports are located in the same plane, the hinge axis of the two supports coincides with the intersection point of the two diagonals of a hypothetical rectangle, and the four traveling wheels on the two supports are respectively located in the hypothetical On the four corners of the rectangle, the articulated four-wheel drive chassis also includes a steering drive assembly for driving the two brackets to rotate relative to each other. The steering method is to control the steering by combining the driving of the steering drive assembly and actively adjusting the rotation speed of each walking wheel, so that the instantaneous steering origin of the articulated frame is located on a straight line passing through the articulated axis and perpendicular to the forward direction. The invention has good driving flexibility , Simple and compact structure, easy to manufacture, low cost, stable and reliable work, precise steering path and other advantages.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a steering method for an articulated four-wheel drive chassis. Background technique [0002] With the support of national policies, new energy vehicles have developed rapidly in recent years. However, most traditional farmland operation vehicles are heavy in weight and high in power consumption, and do not have the conditions for full electrification. However, in fields such as live broadcasting and plant protection, due to the small size and low power consumption of the operating machinery, they have the potential to be fully electrified. [0003] Due to its large steering angle, the articulated body has obvious advantages in driving performance compared with traditional wheeled tractors in the complex driving environment in the south. In recent years, farmland work vehicles based on articulated bodies have also emerged in an endless stream. However, the existing ar...
