Mechanical transmission system and control method of milling machine and milling machine

Abstract

The invention provides a machine driven system and a control method of a milling machine, and the milling machine. The machine driven system of the milling machine comprises a hydraulic clutch, a transmission belt, a belt tightening device and a control device, wherein the hydraulic clutch is arranged between an engine and a driving wheel; starting and separating of the hydraulic clutch are driven by a first hydraulic drive device; the transmission belt is used for transferring power to a driven wheel from the driving wheel, and drives the driven wheel to drive a milling drum to run; the belt tightening device is used for tightening the transmission belt under the drive of a second hydraulic drive device; and the control device is used for obtaining a start signal or a stop signal of the milling machine, and respectively transmitting control signals to the first hydraulic drive device and the second hydraulic device according to a preset order at preset time difference, so as to respectively meet different pressure requirements of the hydraulic clutch and the belt tightening device. Furthermore, start and stop orders of the hydraulic clutch and the belt tightening device can be conveniently set, and abnormal abrasion caused by sliding operation of the belt due to loosing of the belt is avoided.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a mechanical transmission system and a control method of a milling machine and the milling machine. Background technique [0002] Milling machine is one of the main types of asphalt pavement maintenance construction machinery, mainly used for clearing sacks, oil waves, reticulation, ruts, etc. on asphalt concrete surfaces such as highways and urban roads. Because of its high working efficiency, simple construction process, easy control of milling depth, convenient and flexible operation, good maneuverability, and the direct recycling of old milling materials, the milling machine is widely used in urban municipal road and highway maintenance projects. [0003] At present, the power transmission of the milling drum of the milling machine is generally divided into three transmission modes: hydraulic, hydraulic-mechanical hybrid, and mechanical. Among them, the hydraulic transmi...
