Abstract

The invention relates to the field of vehicle running, and discloses a steering mechanism adapted to vehicles with wheel track adjusted. The steering mechanism comprises a frame, an isosceles steering trapezoid MPQN, a right-drive parallelogram ABCD, a right-joint parallelogram DCPM, a left-drive parallelogram EFGH, a left-joint parallelogram HGQN, a right steering knuckle and wheels. Vehicle steering adapted to the vehicles during adjustment of wheel track and after arbitrary wheel track is set up is realized. The invention further provided with a wheel-track stepless adjusting mechanism which is composed of a wheel-track adjustment reserve part and linkage-steering remove part of the steering mechanism adapted to the vehicles with the wheel track adjusted. A front-wheel steering chassis adapted to the vehicles with the wheel track adjusted is characterized by composing of a group of the steering mechanisms and a group of the wheel-track stepless adjusting mechanisms which are adapted to the vehicles with the wheel track adjusted. A four-wheel steering chassis adapted to the vehicles with the wheel track adjusted is characterized by comprising two groups of the steering mechanisms adapted to the vehicles with the wheel track adjusted. Therefore, requirements of agricultural mechanization on different line spacing can be adapted.

Description

technical field [0001] The invention relates to a steering mechanism for a vehicle adapted to wheelbase adjustment, which belongs to the technical field of vehicle chassis, in particular to the technical scope of vehicle steering under the condition of variable wheelbase of the vehicle chassis. Background technique [0002] my country is a vast agricultural country with a wide range of crops. There are many types of crops in the north and the south with great differences. The row spacing of different crops is generally different, and the row spacing of the same crop in different regions or different planting methods is generally different. During the growth period of crops, field management mechanization operations such as weeding, spraying, and fertilization require operating vehicles to walk along the row spacing of crops. Therefore, the wheelbase of the agricultural vehicle chassis is required to be adjusted according to the change of the row spacing of the crops, and an a...
