Pivot steering system and small multi-wheel carrying logistics vehicle

Abstract

The invention discloses an in-situ steering system and a small multi-wheel carrying logistics vehicle, the in-situ steering system is a steering driving system used on the logistics vehicle, the logistics vehicle comprises a lower base and wheels, and the steering driving system comprises an outer shell, a first driving part, a steering device, a transmission device, a connecting shaft and a locking device. The outer shell is arranged below the lower base, the lower portion of the connecting shaft is fixedly connected with the outer shell, the upper portion of the connecting shaft is rotatably connected with the lower base, and the locking device is connected to the lower base and used for preventing the connecting shaft from rotating when the logistics vehicle does not need to steer. The first driving part, the steering device and the transmission device are sequentially connected and used for driving the wheels to steer or walk, the first driving part and the steering device are located in the outer shell, and the transmission device penetrates through the outer shell to be connected with the wheels. The steering device has the advantages of being simple in structure and convenient to steer.

Description

technical field [0001] The invention relates to the technical field of material transportation, in particular to an in-situ steering system and a small multi-wheeled logistics vehicle. Background technique [0002] The world has entered the era of information interconnection, and goods at home and abroad are in the process of continuous circulation. It is often necessary to transfer materials and products. Manual handling is inefficient and requires a lot of manpower and financial resources. It is also prone to safety accidents at times, so the logistics trolley has become one of the commonly used vehicles for the transportation of goods. With the development of logistics, higher requirements are also placed on the functions of the logistics trolley. [0003] The existing logistics trolleys mainly focus on the load of the logistics trolleys, and few people improve the operation mode of the trolleys and improve the convenience of the logistics trolleys. There are the followin...

AI Technical Summary

Problems solved by technology

[0002] The world has entered the era of information interconnection, and items at home and abroad are in the process of continuous circulation. It is often necessary to transfer materials and products. If manual handling is used, the efficiency is low, and it takes a lot of manpower and financial resources. When moving some larger and heavier objects It is also prone to safety accidents, so the logistics trolley has become one of the commonly used vehicles for the transportation of goods. With the development of logistics, the function of the logistics trolley has also put forward higher requirements.

[0003] The existing logistics trolleys mainly make a fuss about the load of the logistics trolley, and few people improve the operation mode of the trolley and improve the convenience of the logistics trolley, which has the following disadvantages: 1) The steering device is complicated, and it is impossible to control the steering simply and effectively

2) In places where the road is narrow, the car cannot turn normally, and the flexibility is poor, resulting in low transportation efficiency

3) When the space is narrow, the trolley cannot turn, and it is difficult to adjust the loading and unloading port to a suitable angle, resulting in inconvenient loading and unloading of goods

4) When walking on uneven roads, the logistics trolley will experience bumps, wheels hanging in the air or even roll over, which has poor adaptability

5) The structure of the braking system is complex and the braking effect is poor
