Description

A kind of parallel connection type hybrid power system compound type speed change driving device
Technical field:
The utility model relates to a kind of block construction of automobile, refers in particular to a kind of parallel connection type hybrid power system variable-speed drive, is mainly used in urban bus and intercity highway passenger vehicle that vapour/diesel motor is an active force.
Background technology:
Automobile has become the indispensable vehicle in modern people's life, yet along with the modern economy development constantly advances with modernization construction, conflicting becoming increasingly conspicuous between the energy, environmental issue and economic development may be the great bottleneck that becomes restriction social and economic development therebetween.Enjoy international community to pay close attention to by the environmental crisis that automobile caused, formulated strict rules to polluting waste gas and greenhouse gas emission respectively, show as follows:
(1) present stage has forced all kinds of automobiles to reach EUROIII Emission Standard, and progressively promotes and carry out Europe IV standard.
(2) EU Committee submitted the strictest automobile greenhouse gas emission plan in the whole world in 2008.In case member government is by motion, by 2012, the average discharge of the domestic new production automobile of European Union must not surpass 130g/km, and present discharging highest standard is 161g/km.So directly require automobile must reach fuel-economizing performance more than 20% when the time comes.
For addressing the above problem effectively, adopting the hybrid vehicle technology will be a practicable solution.Hybrid vehicle utilizes driving engine, motor and closed-centre system exactly, optimizes the power and the driving system of vehicle, realizes saving fuel oil and reduces discharging.
At present, the power system technology of hybrid vehicle mainly contains two big systems, i.e. series connection type hybrid power system and parallel connection type hybrid power system, and various hybrid power system all has oneself characteristics and deficiency.About parallel connection type hybrid power system, main system architecture pattern is as follows:
1, the double mode scheme in parallel of double-motor
The main deficiency of this kind scheme in parallel is:
● electrical motor can not cut off with messenger chain, causes extra waste of power;
● the drive end rotor inertia of power-transfer clutch (rear portion) is excessive, causes this clutch abrasion big;
● messenger chain is longer, is not suitable for the following passenger vehicle of 10.5m;
● be difficult between electric control clutch and manual clutch realize matched well, cause transmission not steady, be not suitable for the frequent road of working conditions change.
2, the scheme in parallel of transmission countershaft
The main deficiency of this kind scheme in parallel is:
● electrical motor can not cut off with messenger chain, causes extra waste of power;
● the tween drive shaft of change-speed box is that rotor inertia is excessive, causes in the change-speed box synchro wearing and tearing big painstaking with gearshift;
3, the scheme in parallel of transmission shaft
Its characteristics mainly are that system's formation is fairly simple, and driving engine, power-transfer clutch, change speed gear box do not need too much change, have inherited the driving type of internal combustion automobile substantially.But messenger chain is oversize, is not suitable for the power postposition of modern bus fully, the requirement of low inlet; Same electrical motor can not cut off with messenger chain; Motor torque is increased, and the power-assisted ability that causes starting to walk is bad.
4, the scheme in parallel of AMT
The main deficiency of this kind scheme in parallel is:
● electrical motor can not cut off with messenger chain, causes extra waste of power;
● motor torque is increased, and the power-assisted ability that causes starting to walk is bad.
Therefore necessary existing parallel connection type hybrid power system structure is improved.
The utility model content:
The purpose of this utility model is at the deficiency of existing parallel connection type hybrid power system, provides a kind of both simple in structure, and the shorter relatively parallel type hybrid dynamic driving of messenger chain, to solve the deficiency of present mixed power system structure.
The purpose of this utility model is achieved through the following technical solutions: a kind of parallel connection type hybrid power system compound type speed change driving device, comprise main gearbox, and main gearbox is many grades of manual or automatic transmission with hydraulic torque converters; Its characteristics are, at the other demultiplicator that is connected with of main gearbox; Demultiplicator directly is assemblied on the body of main gearbox; Described demultiplicator is one single grade of part-time case, and demultiplicator has a main output shaft and two input shafts; Described main output shaft links to each other with the drive axle of vehicle; Described two input shafts, one is the primary input axle, the primary input axle links to each other with the output shaft of main gearbox; Another output shaft is secondary input shaft, and secondary input shaft links to each other with the motor transmission shaft of motor driven systems.The main output shaft of demultiplicator is parallel to each other with secondary input shaft or is vertical, and two between centers rotate with certain speed ratio all the time.
The passenger vehicle change-speed box that this structure is traditional relatively has the following advantages:
1, traditional fuel oil power passenger vehicle only is furnished with main gearbox, is difficult to therefore realize that electrical motor and messenger chain cut off.The utility model can realize very easily that electrical motor and messenger chain cut off after introducing demultiplicator.
2, the main gearbox output shaft is the axle drive shaft of demultiplicator primary input axle, and demultiplicator primary input axle is meshed by gear with the secondary input shaft of demultiplicator, thereby realizes that power is synthetic.
