Description
Technical field
It is idle for improving ISG hybrid power cars more specifically to one kind the present invention relates to the structure of automobile component
Speed taps the structure of abnormal sound.
Background technology
Hybrid vehicle embodies big advantage in terms of energy-saving and emission-reduction, turns into current study hotspot.For mixed
For closing power vehicle, it has different noises to show relative to conventional truck, therefore NVH performances have become hybrid power
The key factor that can car command a ready sale in the market.Idling NVH performance quality directly affects the whole quality of automobile, ISG mixing
There are a variety of idling modes in power car, and a variety of idling modes suffer from special noise and vibration problem.Because ISG is mixed dynamic
The particularity of power car drive assembly structure（Double mass flywheel, ISG motors, CVT speed changers three pass through two pairs of spline strings
Connection）Power assembly employs the connection of two-stage spline, if its spline sideshake is unqualified, will cause double mass flywheel to engine
The effectiveness in vibration suppression of torsional oscillation lowers, and then causes power assembly inner components to tap, and produces abnormal sound.
It is existing to idling tap abnormal sound optimization be concentrated mainly on power assembly structural improvement, spline machining accuracy improve with
And optimize on engine speed fluctuations.There is optimization cycle length in above-mentioned several prioritization schemes, rectification part is more, costly, skill
The features such as art tackling key problem big grade of difficulty is difficult.Based on the situation, a kind of improvement ISG type moderate hybrid power cars need to have been redesigned
Idling spline taps the structure of abnormal sound.
The content of the invention
It is an object of the invention to provide a kind of structure for being used to improve ISG hybrid power cars idling percussion abnormal sound, its energy
Enough on the premise of other performances are not influenceed, the percussion abnormal sound of idling spline is reduced.
The structure of the present invention for being used to improve ISG hybrid power cars idling percussion abnormal sound, including double mass flywheel,
ISG Rotor Assemblies and CVT transmission input shafts, double mass flywheel, ISG Rotor Assemblies and CVT transmission input shafts
Between engine power is sent to by CVT speed changers by the series connection of two pairs of spline structures, in double mass flywheel and ISG rotors
Diaphragm spring is provided between assembly, one end of diaphragm spring is welded on ISG rotors end face, and its middle part is pressed on double matter
Measure on flywheel end face, and can be slided with respect to double mass flywheel, its other end is pressed on ISG rotors end face.
Further, one end that diaphragm spring is pressed on ISG rotors end face is in circular arc.
Further, the diaphragm spring at least two and it is uniformly arranged on rotor end face.
Further, the tranverse sectional thickness of the diaphragm spring is equal.
It is of the present invention to be used to improve the structure that ISG hybrid power cars idling taps abnormal sound, because increase has diaphragm bullet
Spring, the pretightning force of diaphragm spring apply an axial load to double mass flywheel and ISG motors, due to load effect, added
Radial frictional force between double mass flywheel and ISG rotors, in the presence of frictional damping so that double mass flywheel and
ISG motor running speeds tend to be synchronous, eventually reduce due to double mass flywheel and ISG motors spline gaps greatly caused by spline
Tap abnormal sound.Diaphragm spring is uniformly arranged on rotor end face, it is ensured that ISG rotor dynamic balancing is not any
Influence, do not interfere with other performances.

Embodiment
In order to which technical scheme is explained further, next below in conjunction with the accompanying drawings the present invention will be described in detail.
Referring to shown in Fig. 1 to Fig. 6, the structure of abnormal sound, including double quality are tapped for improving ISG hybrid power cars idling
Flywheel 8, ISG motor assemblies and CVT transmission input shafts 9, ISG motor assemblies include ISG Rotor Assemblies 6 and ISG motors
Field frame assembly 7.The first internal spline 10 is provided with double mass flywheel 8, ISG Rotor Assemblies 6 are provided with flower in first
The external splines that key 10 matches, double mass flywheel 8 are connected by the first internal spline 10 and external splines with the key of ISG Rotor Assemblies 6
Connect, be additionally provided with the second internal spline 11 on ISG Rotor Assemblies 6, CVT speed changers by CVT transmission input shafts 9 with
The key connection of ISG Rotor Assemblies 6, make to lead between double mass flywheel 8, ISG Rotor Assemblies 6 and CVT transmission input shafts 9
Cross two pairs of spline structure series connection and engine power is sent to CVT speed changers, in double mass flywheel 8 and ISG Rotor Assemblies 6
Between be provided with diaphragm spring 1, diaphragm spring 1 has four, and it is uniformly arranged on ISG rotors end face, adjacent two diaphragm
90 ° are spaced between spring.Structure, the material of four diaphragm springs 1 are identical with performance, and the thickness of its cross section is equal.Diaphragm bullet
One end 11 of spring 1 is welded on ISG rotors end face 61, and its middle part 12 is pressed on double mass flywheel end face 81, and can phase
Double mass flywheel is slided, its other end 13 is in circular arc, and is pressed on ISG rotors end face 61.
It is shown in Figure 6, internal car noise spectrum line when solid line represents not use apparatus of the present invention vehicle idle, dotted line
Expression employ apparatus of the present invention vehicle it is idle when internal car noise spectrum line.When auto idle speed is run, because double quality fly
Wheel and ISG motors spline gaps 300Hz---800Hz splines caused greatly tap abnormal sound and have obvious improvement.
