Tractor intelligent travelling chassis with compatible transportation and operation functions

Abstract

The invention provides a tractor intelligent travelling chassis with compatible transportation and operation functions. The tractor intelligent travelling chassis comprises a tractor frame, a crawlertravelling system, a wheeled travelling system and an intelligent control system. The crawler travelling system is fixedly connected to the middle of the longitudinal direction of the tractor frame; the wheeled travelling system is connected to the tractor frame and comprises a front wheel travelling mechanism and a rear wheel travelling mechanism; in the longitudinal direction of the tractor frame, the front wheel travelling mechanism and the rear wheel travelling mechanism are located on the front portion and the rear portion of the crawler travelling system correspondingly; a wheel steeringdevice comprises a steering knuckle arm block, a steering rack machine and a steering power cylinder; a wheel steering mechanism is connected with a steering wheel through a steering wheel connectingflexible shaft; and a direction angle sensor is arranged on a rotating shaft of the steering wheel and transmits measured steering wheel rotating angle information to the intelligent control system.The tractor chassis is driven by the intelligent control system and a travelling hydraulic motor to steer, thus the turning radius of the tractor chassis is smaller, and the tractor intelligent travelling chassis is more suitable for field operation and rural narrow roads, and is higher in adaptability.

Description

technical field [0001] The invention relates to a walking chassis of a tractor, in particular to an intelligent walking chassis compatible with transportation and operation. Background technique [0002] Traditional tractors are mostly wheeled tractors, and there are fewer crawler tractors. When working in farmland, wheeled tractors have higher requirements on the road surface, and it is difficult to work after rain, while crawler tractors are energy-saving and have low requirements on the road surface when working in farmland. , Strong adaptability to terrain and other advantages, it is very suitable for farmland operations, but crawler tractors move slowly, and transfer vehicles often need to be pulled away when transitioning, which is very inconvenient. A kind of tractor that can be suitable for farmland operation and road walking is the needs of the current market. In the prior art, patents such as patent CN205311726 U have proposed similar solutions. , but because its ...

[0002] Traditional tractors are mostly wheeled tractors, and there are fewer crawler tractors. When working in farmland, wheeled tractors have higher requirements on the road surface, and it is difficult to work after rain, while crawler tractors are energy-saving and have low requirements on the road surface when working in farmland. , strong terrain adaptability, etc., very suitable for farmland operations, but crawler tractors move slowly, and transfer vehicles often need to be pulled away when transitioning, which is very inconvenient

A kind of tractor that can be suitable for farmland operation and road walking is the needs of the current market. In the prior art, patents such as patent CN205311726 U have proposed similar solutions. , but because its chassis has a crawler drive structure and a wheel-driven differential and bridge structure, the chassis is complicated. When this type of chassis travels in the field, it is easy to cause damage to the differential and bridge structures. On the other hand, the structure of the Chassis steering is difficult to realize, and it is not suitable for the working environment that needs to turn around frequently in a small area, so the patent CN205311726U chassis structure is not ideal for tractors
