Abstract
The utility model belongs to an auxiliary power unit for electric motor coach and wagon in the field of the vehicle-mounted energy storing device. The utility model is provided with an electromagnetic clutch on the belt wheel shaft of the internal-combustion engine with a small power to control the start and close of the air-conditioned compressor; the other belt wheel drives the motor and the small-power generator to start through a belt and to start the motor to drive the steering power-assisted pump and the braking air compressor. The small-power generator generates low voltage power (24V or 42V ) to drive the low voltage electric machine; the rest electric power is used for charging the low voltage electric machine with a battery. The small power internal combustion engine replaces the driving air conditioner, steering and braking system of the auxiliary battery so the steering and braking system of the vehicle need't to be changed a lot; thus the utility model reduces the weight of the whole vehicle, saves the cost and enhances the dynamic force performance and driving distance of the electric motor coach and wagon. The application of the utility model is suitable for the industrialization of the electric motor coach and wagon and the utility model has a great advantage in popularization and use.
Description
Technical field
The utility model belongs to vehicle-mounted closed-center system field, is specifically related to a kind of electronic visitor, lorry auxiliary power unit.
Technical background
From the oil shock of 1973 crisis, because global energy-conservation requirement, the raising fuel economy has become the important topic in the development of automobile.Simultaneously, in the face of increasing environment and energy pressure, developed country has successively proposed very high environmental protection standard to automobile.Under this environment, electronlmobil becomes global auto-domain emphasis research and development object with technical advantages such as its energy-saving and environmental protection, sustainable developments, and increasing people is placed on sight on the electronlmobil in the automotive field.Electronlmobil is widely used in electronic visitor, lorry, and is practical, is the field that is hopeful to realize industrialization most.
Battery is the key components of electronlmobil as the main or auxiliary power source of electronlmobil.At present, general one group of master battery pack battery that is used as power that adopts on electronlmobil is joined annexes such as one group of auxiliary battery banks drives air-conditioning, turns to, braking in addition.Battery pack as the important component part of electronic visitor, lorry, too much use in electronic visitor, lorry has not only increased complete vehicle quality, and has increased the manufacturing cost and the use cost of car load, particularly for the higher lithium cell of cost, the increase of cost is especially obvious.Simultaneously, the increase of deadweight has also influenced the power index and the continual mileage of electronic visitor, lorry to a great extent.
Summary of the invention
The purpose of this utility model is to have proposed a kind of electronic visitor, lorry auxiliary power unit, and the actuating device of described electronic visitor, lorry drives automobile by power battery pack, joins one group of auxiliary power unit in addition and drives air-conditioning, turns to and brake system; It is characterized in that: described electronic visitor, lorry auxiliary power unit are on the axle of the belt pulley 5 of miniwatt combustion engine 6 magnetic clutch 11 to be installed, and are connected by the belt pulley 5 on 9 of belt 10 and the main generators again, and main generator 9 is connected with power battery pack 13; The belt pulley 5 of miniwatt combustion engine 6 fan end is connected with small power generator 8 with starter motor 7 respectively by belt 10; The output of small power generator 8 is connected with storage battery 4 with low-voltage electrical apparatus with low-voltage electrical apparatus 3; Starter motor 7 is connected with steering swivel system 2 with brake system 1 by belt pulley 5, belt 10.
The beneficial effects of the utility model are at the deficiencies in the prior art, by selecting suitable combustion engine to drive air-conditioning, turn to and equipment such as braking, with make vehicle-mounted closed-center system with storage battery, and when selecting the miniwatt combustion engine, considered the influence of rate of load condensate, by suitable raising rate of load condensate, make the driving engine stable operation in the optimum oil consumption zone, thereby the rate of load condensate of combustion engine is controlled at best operation point reaches energy-conservation purpose, simultaneously because the work of combustion engine is not subjected to the influence of road conditions, be operated in the stable rotating speed scope, therefore the discharging that is produced also is very low, has satisfied environmental protection requirement.When taking into account environmental protection, owing to replace auxiliary battery banks to drive air-conditioning, turn to and brake system with the miniwatt combustion engine, alleviate complete vehicle weight, effectively reduced the manufacturing cost and the use cost of electronic visitor, lorry, improved the tractive performance and the continual mileage of electronic visitor, lorry.

Fig. 2 is the universal characteristic analysis chart.
The specific embodiment
The utility model proposes a kind of electronic visitor, lorry auxiliary power unit, the actuating device of described electronic visitor, lorry drives automobile by power battery pack, joins one group of auxiliary power unit in addition and drives air-conditioning, turns to and brake system; In the structural representation of electronlmobil auxiliary power unit shown in Figure 1, on the axle of the belt pulley 5 of miniwatt combustion engine 6, magnetic clutch 11 is installed, be connected by the belt pulley 5 on 9 of belt 10 and the main generators, main generator 9 is connected with power battery pack 13 again; The belt pulley 5 of miniwatt combustion engine 6 fan end is connected with small power generator 8 with starter motor 7 respectively by belt 10; The output of small power generator 8 is connected with storage battery 4 with low-voltage electrical apparatus with low-voltage electrical apparatus 3; Starter motor 7 is connected with steering swivel system 2 with brake system 1 by belt pulley 5, belt 10.
Its principle of work for the startup of the magnetic clutch 11 control air-conditioning compressors 12 on 5 of the belt pulleys of miniwatt combustion engine 6 with close, the belt pulley 5 of the fan end of miniwatt combustion engine 6 drives starter motor 7 and small power generator 8 respectively by belt 10, small power generator 8 produces low tension (24V or 42V) and drives low-voltage electrical apparatus 3, and dump power is charged with storage battery 4 to low-voltage electrical apparatus; Starter motor 7 drives brake system 1 and steering swivel system 2 by belt pulley 5, belt 10.During automobile normal running, drive automobile by power battery pack, combustion engine 6 starts simultaneously, when needs use air-conditioning, gives air-conditioning compressor 12 direct drive air-conditionings by magnetic clutch 11 with transmission of power; When air-conditioning time spent not, cut off the power of combustion engines 6 and 12 of air-conditioning compressors by magnetic clutch 11, charge for power battery pack 13 simultaneously transmission of power for main generator 9, unnecessary electric energy is converted into electric power is stored to power battery pack.This device belongs to light hybrid, be when selecting the miniwatt combustion engine, by carrying out the calculating of power match, adjust the rate of load condensate of driving engine, the rotating speed of driving engine is controlled in the economic speed scope, make the operation point of driving engine be in shadow region 16 among Fig. 2, guarantee fuel economy thus.In Fig. 2: abscissa is engine speed n, and ordinate is motor torque Ttq, and curve 14 is for waiting oil consumption line, and curve 15 is an equipower line.The utility model is in the process of implementing, and turning to and not braking and need do big change of former car improved fuel economy by preferred combustion engine; Replace auxiliary battery banks to drive air-conditioning, turn to and brake system with the miniwatt combustion engine, alleviated complete vehicle weight, provide cost savings, improved the tractive performance and the continual mileage of electronic visitor, lorry.Application of the present utility model helps the industrialization of electronic visitor, lorry, has very big advantage in promoting the use of.
