Steering mechanism adapted to wheel base adjustment chassis

Abstract

The invention relates to the field of vehicle traveling and discloses an underpan steering mechanism suitable for regulation of a wheel track. The underpan steering mechanism comprises a frame, a driving link, steering slides, balance bars, a steering rod, front and rear connecting rods, guide rods, steering arms, steering knuckles and wheels, wherein the front and rear connecting rods, the guide rods, the steering arms, the steering knuckles and the wheels are respectively and laterally symmetrical. The linkage steering isosceles trapezoid ABFE following regulation of the wheel track implements the effect that in the wheel track regulating process and after a random wheel track is set, the underpan steering mechanism can be suitable for running steering of a vehicle. The invention also provides a vehicle wheel track stepless regulation mechanism which is formed by parts in the underpan steering mechanism suitable for regulation of the wheel track, in which a wheel track regulation part is reserved and a linkage steering part is removed. A vehicle front wheel steering underpan suitable for regulation of the wheel track is formed by one set of underpan steering mechanism suitable for regulation of the wheel track and one set of vehicle wheel track stepless regulation mechanism and a vehicle four-wheel steering underpan suitable for regulation of the wheel track is formed by two sets of the same underpan steering mechanisms suitable for regulation of the wheel track, so that the requirements on mechanical operation on crops with different line spacings can be met.

Description

technical field [0001] The invention relates to a steering mechanism adapted to a wheelbase adjustment chassis, which belongs to the technical field of vehicle chassis, and in particular relates 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, ...

AI Technical Summary

Problems solved by technology

At present, the steering mechanism of domestic tractors and agricultural power chassis is generally Ackerman trapezoidal steering mechanism, which cannot meet the requirements of the steering mechanism and wheelbase adjustment in chassis with adjustable wheelbase.
