When working, the oil pump motor drives the whole unit, the performance is reliable, low power consumption and less pollution, the maintenance cost is reduced, the energy conservation effect is outstanding, the economic efficacy gains a 50% growth, the utility model can serve as the engine driving system for the automobile crane.
Description
Technical field
The utility model relates to a kind of Power Drive Unit of car hosit.
Background technology
The Power Drive Unit of known car hosit adopts combustion engine as propulsion source, drives the oil pump group, finishes required action for car load.Because Internal-Combustion Engine Maintenance cost height, driving engine must be worked all the time during operation, and the work-site noise is big, the exhaust emission serious environment pollution, and oil consumption is many, so the use cost height of car hosit.
Summary of the invention
The purpose of this utility model is that a kind of car hosit power-driven system will be provided, and this system's power consumption is few, and maintenance capacity is few, and use cost is low.
The purpose of this utility model is achieved in that this power-driven system comprises driving engine, power takeoff and oil pump group, be connected with the rotating speed control mechanism between the Das Gaspedal of getting on the bus and the driving engine, be connected with power takeoff between driving engine and the oil pump group, oil pump group oil outlet and get on the bus and be connected with the load sensing hydraulic manifold block between the oil pipe, be connected with the variable capacity oil pump group of motors between load sensing hydraulic manifold block pressure hydraulic fluid port and the hydraulic servo proportional valve control hydraulic fluid port, hydraulic servo apportioning valve static pressure hydraulic fluid port is connected with the rotating speed control mechanism, and hydraulic servo apportioning valve oil inlet is connected with quantitative control Oil pump electrical machinery.
The utility model has increased by a cover Oil pump electrical machinery drive system on former internal combustion engine system basis, during normal operation, drive car load work by Oil pump electrical machinery, and performance is safe and reliable, and it is low to consume energy, and pollutes and lacks, and maintenance capacity is few, has reduced use cost.Energy-saving effect is remarkable, calculates by 60 tons of materials of operation lifting, and former internal combustion engine system usage charges need 96 yuan, and the native system usage charges only are 42 yuan, and economic benefit improves 50%.It is all commercially available that this system makes required parts, makes easily.
