Abstract
The utility model relates to a land scraper walking hydraulic driving device, which belongs to the technical field of land scrapers. In the land scraper walking hydraulic driving device, an engine is arranged on a stander, and the engine drives wheels. The land scraper walking hydraulic driving device has the characteristics that a hydraulic pump is transmitted by the engine; the hydraulic pump is transmitted to a hydraulic motor through the connection of pipelines; the hydraulic motor is connected with a rear axle and a front axle; the connection transmission of the rear axle and the front axle is output to wheels to drive the land scraper to operate and travel. The land scraper walking hydraulic driving device has high efficiency of direct transmission as well as the flexibility of hydraulic transmission and greatly improves the comfort of the operation, and has the advantages of fuel oil conservation and environment protection, etc., the engine power is exerted to the utmost extent, and the pulling capacity of the land scraper is improved.
Description
Technical field
The utility model belongs to the road grader technical field, particularly relates to a kind of road grader walking fluid pressure drive device.
Background technology
At present, road grader had both required big tractive force operation as a kind of traction transportation type construction machinery and equipment, required the higher speed of a motor vehicle to travel again.In the existing road grader, generally all form by (1) driving engine, master clutch, change speed gear box, back axle, tandem-driving bogie, wheel etc.This structure is the gear shift difficulty, and master clutch is thrown off, and carries out gear shift then.(2) compositions such as driving engine, turbine transformer, change speed gear box, back axle, tandem-driving bogie, wheel.The shortcoming of this structure is that turbine transformer efficient is low, and the fuel oil waste is bigger.(3) compositions such as driving engine, pump, motor, tandem-driving bogie, wheel.This structure is because Transmission is less, and ratio coverage is narrow, makes road grader can not take into account maximum speed and minimum speed.
From as can be seen above, 3 kinds of structures all have special-purpose back axle and tandem-driving bogie, exist batch less, and cost is very high, can not use the big in batches problems such as parts of construction machinery and equipment general-duty.
Summary of the invention
The technical matters of the utility model for existing in the solution known technology, and a kind of road grader walking fluid pressure drive device is provided.
The purpose of this utility model provides the high advantage of a kind of advanced in performance, existing direct drive efficient, and the flexibility of hydraulic transmission is arranged again, improves the handling comfort of road grader greatly, has the road grader walking fluid pressure drive device of energy-conserving and environment-protective characteristics.
The utility model is taked following technical scheme:
Road grader walking fluid pressure drive device, driving engine is housed on the frame, engine driven wheel, be characterized in: the engine-drive Hydraulic Pump, Hydraulic Pump connects by the road and drives to HM Hydraulic Motor, HM Hydraulic Motor is connected with propons with back axle, and back axle is connected with propons and drives output to wheel, drives the road grader operation and travels.
The utility model can also adopt following technical measures:
Described road grader walking fluid pressure drive device, be characterized in: Hydraulic Pump is housed on the driving engine, and Hydraulic Pump links to each other with two HM Hydraulic Motor by pipeline.
Described road grader walking fluid pressure drive device, be characterized in: HM Hydraulic Motor connects the driving change speed gear box, and change speed gear box links to each other with the input end of back axle.
Advantage that the utlity model has and good effect:
Road grader walking fluid pressure drive device is owing to adopted technical solutions of the utility model; the speed of road grader is changed with the variation of loading with external force; realize that by motor switch 4 take turns the driving of taking turns with 2; can realize stepless change; reduce shifting shock; make manipulation simpler; comfortable; simultaneously when throttle reduces; the flow of pump also reduces thereupon; play the effect that continues braking, driving oil pump and CD-ROM drive motor is to be provided with according to the output characteristic curve of driving engine, brings into play the power of driving engine to greatest extent; protect driving engine and drive disk assembly effectively; save fuel oil, improve the towability of road grader.
Description of drawings
Fig. 1 is a connection structure scheme drawing of the present utility model.
Among the figure, 1-wheel, 2-HM Hydraulic Motor, 3-driving engine, 4-Hydraulic Pump, 5-Hydraulic Pump, 6-HM Hydraulic Motor, 7-propons, 8-drop-gear box, 9-back axle.
The specific embodiment
For further understanding content of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Consult accompanying drawing 1.
Embodiment 1
Road grader walking fluid pressure drive device is equipped with driving engine on the frame, engine driven wheel is equipped with Hydraulic Pump 4 and 5 on its driving engine 3.Hydraulic Pump 5 connects two HM Hydraulic Motor 2 of transmission by pipeline, and HM Hydraulic Motor 2 is connected with propons 7, and propons 7 connections drive output to wheel 1.Hydraulic Pump 4 connects two HM Hydraulic Motor 6 of transmission by pipeline, and HM Hydraulic Motor 6 connects driving change speed gear box 8, and change speed gear box 8 links to each other with the input end of back axle 9.Back axle 9 connects and drives output to wheel, drives the road grader operation and travels.
Present embodiment is the actuating device of the all-hydraulic all-wheel drive road grader of a kind of 4X4, mainly be to replace traditional power-transfer clutch direct drive or turbine transformer with Hydraulic Pump, the high advantage of existing direct drive efficient, the flexibility that hydraulic transmission is arranged again, improve the handling comfort of road grader greatly, characteristics with energy-conserving and environment-protective, 2 wheel drive during walking, 4 wheel drive during operation.
