Articulated type four-drive chassis and steering method thereof

Abstract

The invention discloses an articulated type four-drive chassis and a steering method thereof. The articulated type four-drive chassis comprises an articulated vehicle frame articulated by two supports, two walking wheels driven by an independent rotary driving device are mounted on each support, the four walking wheels on the two supports are located in the same plane, the hinge axes of the two supports coincide with two diagonal intersection points of an assumed rectangle, the four walking wheels on the two supports are arranged on four corners of the assumed rectangle correspondingly, and the articulated type four-drive chassis further comprises a steering driving assembly used for driving the two supports to rotate relatively. The articulated type four-drive chassis has the advantages of being good in driving flexibility, simple and compact in structure, easy to manufacture, low in cost and stable and reliable in work, the steering method is combined with driving of the steering driving assembly and actively adjusting the rotating speed of each walking wheel to control the steering, and the steering method can guarantee the steering path precision.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to an articulated four-wheel drive chassis and a steering method thereof. 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 exi...

AI Technical Summary

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
