Abstract

The invention discloses a novel hydraulic vibration system and a road roller. The vibration system comprises a hydraulic pump, a first hydraulic motor and a second hydraulic motor, wherein the workingend of the hydraulic pump is connected with the first hydraulic motor and the second hydraulic motor in parallel, the working end of the first hydraulic motor is connected with a first driving shaft,and the working end of the second hydraulic motor is connected with a second driving shaft; the first driving shaft is connected with a first vibration exciter, and the second driving shaft is connected with a second vibration exciter; the hydraulic pump works to drive the first driving shaft and the second driving shaft to rotate at the same time through the first hydraulic motor and the secondhydraulic motor, the first driving shaft drives the first vibration exciter to work, and the second driving shaft drives the second vibration exciter to work. The two hydraulic motors are connected inparallel, the pressure requirement of the system is low, and the service life of hydraulic system elements is relatively long.

Description

technical field [0001] The invention relates to the technical field of hydraulic systems, in particular to a novel hydraulic vibration system and a road roller. Background technique [0002] At present, the vibrating wheel with dual-axis drive (using the eccentric mechanism inside the vibrating wheel of the road roller driven by the dual-axis drive) in the industry is generally used to achieve vertical vibration or oscillation, and a single hydraulic motor is generally used to drive the drive shaft. Such as figure 1 As shown, the engine drives the high-pressure oil output by the hydraulic pump to enter the hydraulic motor, and the hydraulic motor transmits the power to the drive shaft of a vibrator. At the same time, the drive shaft is equipped with gears, and the power is transmitted synchronously and reversely to another exciter through gear meshing. The drive shaft of the exciter, so as to realize the synchronous direction rotation of the two exciters. [0003] Vertical...
