Hydraulic driving device with shock absorber

Abstract

The invention discloses a hydraulic driving device with a shock absorber. The hydraulic driving device comprises a steering wheel hydraulic driving device, a shock-absorption main shaft mechanism and a rotary coupler, wherein the shock-absorption main shaft mechanism is connected with the steering wheel hydraulic driving device; the rotary coupler and the shock-absorption main shaft mechanism are integrally connected; the rotary coupler is arranged at the upper end of the shock-absorption main shaft mechanism and can rotate for any angle around the shock-absorption main shaft mechanism; the shock-absorption main shaft mechanism is internally provided with a plurality of high-pressure oil paths which are communicated with the steering wheel hydraulic driving device; the rotary coupler is provided with a plurality of oil openings communicated with the high-pressure oil paths; the oil openings are externally connected with an oil path of a hydraulic control system. The hydraulic driving device disclosed by the invention can realize the rotation of any angle so that a mounting structure is simplified, the volume is compact, the weight is light, the adjustment is convenient, leaking links are reduced, the pressure loss is reduced, the system efficiency is improved, the maintenance, the assembling and the disassembling are convenient, the appearance is beautiful, the performance is reliable and the passing ability is good.

Description

technical field [0001] The invention relates to the technical field of hydraulic traveling machinery, agricultural traveling machinery and transplanting machinery, in particular to a hydraulic drive device with a shock absorber. Background technique [0002] With the continuous development of hydraulic walking machinery, higher requirements are put forward for hydraulic drive devices.
