Description
Technical field
The utility model belongs to the technical field of hybrid power of self-propelled vehicle, specifically increases a kind of hybrid vehicle power steering connection structure of power drive system on the basis of engine drive system.
Background technology
Serious year by year along with the exhausted day by day and problem of environmental pollution of the energy, countries in the world are more and more paid attention to the energy-conserving and environment-protective problem.And auto-industry are in more than 100 year of its development, though energy-conservation, pollute, discharging and have all obtained significant improvement and significant progress aspect some other, the pollutants that its tail gas is discharged is still the primary pollution source of current earth atmosphere.Auto trade has consumed a big chunk of world oil output, and according to statistics: the energy consumption of the vehicle accounts for 40% of world's total energy consumption, and the energy-output ratio of automobile accounts for 1/4.Along with increasing year by year of automobile pollution, the consumption of petroleum amount also can increase thereupon, and therefore the automobile of exploitation and applicating energy-saving cleaning is extremely urgent.Under this overall background, pure electric vehicle technology, fuel cell technology, hybrid power technology, other substitute fuel technology etc. are arisen at the historic moment.Wherein, the hybrid power technology is to have taken into account the best of breed of environmental protection and energy saving and industrialization feasibility, is the important directions of the development coming years.The research and development hybrid power technology of doing one's utmost in domestic and international each motor plant commercial city.The PHEV of Ti Chuing (the plug-in hybrid car can use domestic power grid to be power battery charging, and the pure motor driving mileage is longer) had very long life cycle in recent years.
Hybrid vehicle is realized the order ground of energy-saving and emission-reduction by following approach:
Tail-off when 1, stopping, the cancellation idling is used motor quick operated start driving engine when restarting.
2, reduce engine swept volume, improve the dynamic property of car load by the motor power-assisted.
3, optimize engine working point, improve engine operation efficient
4, reclaim braking energy by electrical generator
5,, avoid engine operation high and discharge abominable operating mode in oil consumption at starting and pure motor driving during low speed.
Can run into such problem in exploitation during hybrid vehicle: hybrid vehicle is during at tail-off, and the engine-driven power steering pump with intergral reservoir of former cause also needs work under some operating mode.Power steering pump with intergral reservoir can consume a lot of energy so in vain as long as engine running turns to demand all will rotate no matter have or not.The way that solves can adopt the electric turning booster pump, but present most vehicle also is to use the conventional hydraulic power assistance pump for steering, electric turning booster be not very ripe, cost is high; Hybrid vehicle is to develop on the basis of traditional vehicle mostly, uses electric turning booster bigger to the change of prototype engine, so be not best solution.This is the key factor that up to the present numerous domestic hybrid power vehicle does not also have extensive industrialization.
Summary of the invention
The purpose of this utility model just provides a kind of hybrid vehicle power steering connection structure that increases power drive system on the basis of engine drive system.The problem that problem that power steering pump with intergral reservoir can't be worked when solving the hybrid electric vehicle engine shutdown with lower cost and to former car change is less and power steering pump with intergral reservoir change often in engine operation.
The purpose of this utility model is achieved in that it includes: driving engine, hydraulic powered steering pump, the dynamo belt train, it is characterized in that: be provided with an electric control clutch that makes engine crankshaft and this belt train disconnect or combine between engine crankshaft front end and the dynamo belt train, between hydraulic powered steering pump and engine wheel system, also be furnished with one be used in conjunction with or cut off the electric control clutch that this train passes to hydraulic powered steering pump power; The input end of electric control clutch and electric control clutch is connected with the mouth of entire car controller respectively, and the entire car controller input end then links to each other with the mouth of steering wheel angle sensor; The engine belt pulley that is connected with hydraulic powered steering pump is fastened the startup generating integral type motor that also is fixedly connected with a belt drive, and this starts generating integral type motor and is connected in series with startup generating integral type electric machine controller and electrokinetic cell by lead.
If this organization plan as the platform of plug-in hybrid car, then also is connected with a charging unit on electrokinetic cell.
((being called for short: the BSG motor)) is by its output shaft and motor pulley and belt train bonded assembly to the startup generating integral type motor of belt drive, we can say that also this motor pulley has become the part in the belt train.
Electrokinetic cell of the present utility model can use Ni-MH battery, lithium ion battery etc., and parameters such as its capacity, specific power if this platform is used to develop the plug-in hybrid car, need to increase charging unit by the design plan and the decision of realization target of hybrid power.
This technical scheme has following advantage:
1) simple in structure, cost is low.Only need increase electric control clutch, electric control clutch controller, steering wheel angle sensor, BSG motor can realize the purpose of this utility model.
2) former truck system is carried out less change, can solve the hybrid vehicle problem that power steering pump with intergral reservoir can't drive when tail-off.And power steering pump with intergral reservoir when nothing turns to demand and engine wheel system disconnect, can energy savings, further improve the fuel economy of hybrid vehicle.Hybrid vehicle all is to develop on the basis of traditional vehicle usually, and former truck system is changed I to save cost of development, to shorten time-to-market.
