Abstract

The invention relates to a driving type road milling machine gear shifting device. The device comprises a gear push rod, a connection unit, a linkage and a hydrostatic transmission unit. The gear push rod is connected with the upper end of the linkage through a connection unit, and the lower end of the linkage is connected with the hydrostatic transmission unit. The hydrostatic transmission unit is in transmission connection with a drive wheel of the road milling machine through a plurality of chain wheels. According to the device, the gear push rod controls the hydrostatic transmission unit through the linkage, the hydrostatic transmission unit transmits power to the drive wheel through the chain wheels, and accordingly, various traveling speeds can be selected according to various working conditions, and the work efficiency and the work quality are improved.

Description

technical field [0001] The invention relates to the technical field of milling machines, in particular to a shifting device of a driving type road milling machine. Background technique [0002] The road milling machine is a kind of engineering machinery that re-paves the road material after crushing and collapsing the road material. Road milling machines are generally operated manually, and the milling speed is manually controlled. The speed is uneven, the milling effect is poor, and the work efficiency is low. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a gear shifting device for a driving type road milling machine that can select multiple walking speeds and improve work efficiency. [0004] The technical solution for realizing the purpose of the present invention is: a gear shifting device for a driving type road milling machine, which has a gear push rod, a connecting device, a connecti...
