Problems solved by technology

The axles used in the above-mentioned plant protection machinery have the following problems and shortcomings: the shape and structure are unreasonable, and it is easy to cause the phenomenon of scraping seedlings and pressing ridges
The transmission ratio is not accurate, tires are eaten during use, and power loss is large
The connection method of the steering support is unreliable, which may easily cause the connection to become loose
Unreasonable deflection angle of the steering knuckle will affect the overall strength of the axle and easily cause loose connection
Unreasonable inclination angle of drive shaft affects steering flexibility and load distribution

Abstract

The invention provides a hydraulic steering four-wheel drive axle of a plant protection machine. The axle comprises a horizontal main reduction gear box assembly, the two ends of the main reduction gear box are respectively and rotatably provided with a vertical knuckle assembly, the two knuckle assemblies are symmetrically arranged, the tail end of each knuckle assembly is provided with a tail end transmission assembly through a fastener, a steering mechanism used for driving the two knuckle assemblies to steer is arranged between the two knuckle assemblies and the main reduction gear box, a first included angle is formed between a knuckle pin shaft of the two knuckle assemblies and the vertical direction, and a second included angle is formed between a tail end drive shaft of the two tail end transmission assemblies and the horizontal direction. The axle is reasonable in structure and compact and attractive in appearance, passing ability is obviously improved during field work, steering, supporting and connection are firm, reliable and flexible, a tail end structure mode is improved, and passing ability is optimized.

Description

technical field [0001] The invention relates to the technical field of plant protection machinery, in particular to a hydraulic steering four-wheel drive axle for plant protection machinery. Background technique [0002] At present, the commonly used plant protection machinery mainly includes high ground clearance spraying machines, fertilizer spreaders, transport machines, and paddy field multifunctional machines. The drive axle is an important part of plant protection machinery. The drive axle is generally composed of a differential (the differential is mainly composed of The main reducer, the planetary gear train), the half shaft connected to the two sides of the differential, the wheel transmission connected to the half shaft, and the drive axle housing. Its function is to bend the power from the engine through an angle of 90°, change the direction of force transmission, reduce the speed by the final reducer, increase the torque, and distribute it to the left and right a...
