The utility model relates to a hydraulic transmission device of a trailing vibration road roller, a hydraulic pump which is driven by an engine and a hydraulic pump drive two hydraulic motors which are connected with each other in parallel, each hydraulic motor drives an eccentric shaft to make a vibrating drum to work, and each hydraulic motor is controlled by two-position four-way spill valve; an accelerator of the engine is automatically controlled through an accelerator tension spring, an accelerator rod, a flow regulating valve and a single acting cylinder, and the rotation speed of the engine is synchronous with the hydraulic motor. The utility model has the advantages of simple structure, easy fabrication and convenient operation, can avoid that the vibration of the vibrating drum is directly transmitted to a machine frame and enhance the production efficiency and the service life of the utility model.
