Steering system, vehicle and vehicle steering method

Abstract

The invention relates to a steering system, a vehicle and a vehicle steering method. The steering system comprises a plurality of wheel sets, suspension assemblies (4) and rotation driving devices (3), wherein at least one of the wheel sets comprises two wheels (2); the number of the suspension assemblies (4) is the same as that of the wheel sets, and the suspension assemblies (4) are correspondingly connected with the wheel sets; and the number of the rotation driving devices (3) is the same as that of the suspension assemblies (4), and the rotation driving devices (3) are correspondingly connected with the suspension assemblies (4) and are used for driving the correspondingly connected suspension assemblies (4) to rotate so as to drive the corresponding wheel sets to achieve independentsteering. The vehicle comprises the steering system. According to the invention, each wheel set can realize independent steering so as to enable the vehicle to have higher steering flexibility; the structure is simpler, and the occupied size is small; moreover, the steering angle of the rotation driving device is large, so that the turning radius is effectively reduced, and tire abrasion is reduced; and the supporting capacity is better, and the vehicle stability is good.

Description

technical field [0001] The invention relates to the technical field of vehicle machinery, in particular to a steering system, a vehicle and a vehicle steering method. Background technique [0002] Unmanned intelligent guidance and transshipment equipment for port containers is a transportation equipment used in automated or semi-automated terminals. It has the characteristics of unmanned driving, automatic navigation, accurate positioning, path optimization, and safety collision avoidance, and can automatically Moving transport vehicles. With the application of new control algorithms and the development of electronic technology, unmanned intelligent guided transfer equipment is developing towards high precision, intelligence, high efficiency, and networking. Therefore, it is required that the transfer equipment must achieve efficient and high-precision steering. [0003] The steering system is the main device to control the driving route and direction of the transfer equipm...

AI Technical Summary

Problems solved by technology

The steering system has a simple structure and is easy to manufacture. However, due to its structural limitations, the range of steering angles is limited, resulting in limited steering modes, which limits the flexibility of the steering of the car body, and requires a lot of space when steering.

Because the steering system includes hydraulic cylinders, slewing supports, etc., it takes up a lot of space in the car body during installation, which is not conducive to the simplification of the vehicle's volume and weight, and the electro-hydraulic control system of the steering mechanism is also relatively complicated.

In addition, due to the sliding situation when turning, the tires are more worn

[0005] It can be seen that the existing steering system occupies a large volume and weight of equipment, but the steering angle is small (not exceeding 40°), there are few steering modes, the minimum turning radius is large, a large space is required for steering, and tire wear is serious, etc.
