Title:

TRACTOR REAR SUSPENSION VIBRATION DAMPING CONTROL SYSTEM AND TRACTOR

Document Type and Number:

WIPO Patent Application WO/2023/216574

Kind Code:

A1

Abstract:

A tractor rear suspension vibration damping control system, relating to the technical field of tractor rear suspension vibration control. The system comprises: a tractor operation parameter acquisition device for acquiring an operation parameter of a tractor; a controller (11) for sending a control signal to an execution mechanism according to the acquired operation parameter of the tractor and a set vibration damping control policy; the execution mechanism for controlling, according to the control signal sent by the controller (11), the amount of a hydraulic fluid flowing into or out from a rodless cavity of a suspension cylinder (8) of a tractor rear suspension mechanism, so that the tractor rear suspension mechanism performs vibration damping during a transfer process and is kept in a set damping range, thereby effectively controlling the vibration of a tractor rear suspension, improving the driving comfort of an operator, and avoiding a safety problem caused by overlarge vibration. The present invention also relates to a tractor.
