Specific implementation mode
Shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the present invention is by taking four road gear-type hydraulic syncmotors as an example, including hydraulic synchronization
Motor body 1 and external control type valve group 2, external control type valve group is mounted on the output end of hydraulic synchronous motor ontology, in external control type valve
Group is equipped with external control hydraulic fluid port X, T.Hydraulic synchronous motor ontology is independent on oil circuit by four, and one is rigidly attached in transmission
The hydraulic motor composition risen.The input terminal of four hydraulic motors 6 is ganged up together, and output end is respectively independent, in hydraulic synchronization
Oil inlet P 1, P2 and four independent oil outlet A1, A2, A3, A4 being connected to there are two being set on motor body 1, in four hydraulic pressure
