Abstract
The utility model provides a hydraulic power output mechanism for a track type operation machine, comprising a hydraulic power system and a power output unit, wherein the power of the hydraulic power system is supplied by an engine, and the power output unit is controlled by the hydraulic power system. The power output unit comprises a hydraulic motor connected to the hydraulic power system and a connecting sleeve connected to the output shaft of the hydraulic motor, and the connecting sleeve is connected with a rotating shaft of an operation device. In the utility model, the discharge capacity of an oil pump is directly controlled by the engine without a clutch which is mechanically driven, and the rotate speed and the torque of the hydraulic motor are further controlled, thereby the rotate speed control of stepless speed change from 540 revolutions to 1000 revolutions is realized, the power transmission is stable, and the control is more convenient. In addition, the utility model has the advantages of simple structure, convenient maintenance, light weight and the like.
Description
Technical field
The utility model relates to a kind of power take-off mechanism of crawler type working rig, especially relates to a kind of hydraulic power output mechanism that is used on the crawler type working rig.
Background technology
In existing technology, what crawler-mounted engineering or agricultural machine adopted basically to the power transmission of equipment is the mechanical type transmission, need freestanding power-transfer clutch, could realize that by the output speed of control motivity 540-1000 changes the rotating speed control that level is arranged.There is complex structure, technical matters such as weight is bigger.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, weight light, can realize from 540 forwarding the 1000 infinite variable speed rotating speeds controls of changeing to and the stable fluid pressure type power take-off mechanism of power transmission.
The technical solution of the utility model is to comprise by driving engine the hydraulic power system of power, the power take-off unit that controlled by hydraulic power system are provided, wherein, power take-off unit comprises HM Hydraulic Motor that is connected in hydraulic power system and the adapter sleeve that is connected in hydraulic motor output shaft, and described adapter sleeve is connected with the turning cylinder of equipment.
Further, described hydraulic power system comprises fuel tank, filter, hydraulic oil pump, multi-way control valve and by pass valve, and wherein the hydraulic oil in the fuel tank filters the back repairing through filter and gives hydraulic oil pump; Hydraulic oil pump is the multi-way control valve fuel feeding by engine drive; Wherein one tunnel control power take-off unit of multi-way control valve; By pass valve overflows back fuel tank with the hydraulic oil that surpasses authorized pressure in hydraulic oil pump, the multi-way control valve.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, need not through mechanically operated power-transfer clutch, directly pass through the displacement size of engine control oil pump, come the rotating speed and the moment of torsion of modulated pressure motor, can realize forwarding the 1000 infinite variable speed rotating speed controls of changeing to from 540, and power transmission is stable, and controls convenient; And have advantages such as simple in structure, easy to maintenance, lighter weight.
