Description
Technical field
The utility model relates to new energy vehicle component improvement technology, especially a kind of new-energy automobile series connection vibration damper complement.
Background technique
In the new energy vehicle, two and above power source are arranged usually, flywheel vibration damper or the single vibration damper of common vehicle (mainly being made of dish core, damper disc assembly, pre-damper disc assembly) are adopted in the connection between main two power source transmission shafts usually.Because torsional impact was very big when vehicle power switched, therefore adopt above-mentioned two kinds of vibration dampers to the problem that legacy system brings to be: the fracture of junction parts, axle fracture, vibration is big.
Summary of the invention
The purpose of this utility model is to solve the vibration damper that uses in the existing new energy vehicle can not satisfy the transmission needs, makes the vehicle component fracture easily, vibrates big problem, and a kind of new-energy automobile series connection vibration damper complement is provided.
Concrete scheme of the present utility model is: new-energy automobile series connection vibration damper complement, has the dish core, main damper disc assembly and pre-damper disc assembly with dish core retainer plate dress, it is characterized in that: be in series with several secondary damper disc assemblies with main damper disc assembly, Placement in twos is: the drive plate in the previous damper disc assembly adopts some bolton to be connected with clamping disk in the back damper disc assembly, and between drive plate and clamping disk separation sleeve is being housed on the bolt.
Main damper disc assembly described in the utility model and secondary damper disc assembly all are made up of drive plate, clamping disk, shock-absorbing spring, damping fin, dish spring.
Pre-damper disc assembly described in the utility model is made up of pre-damping disk(-isc), dish cover, pre-shock-absorbing spring.
New energy vehicle and conventional automobile compare, and power source has more than 2, and the car load Parts for Power Train is many, and power train inertia is big, and is big for the impact of coupling member.Therefore the vibration damper in the new energy vehicle should have three big functions:
1. transmit moment of torsion (energy): need to satisfy torque demand;
2. slow down impact: windup-degree should be big as much as possible, and rigidity is as far as possible little;
3. protection power train.
Vehicle is under the situation of high-speed working condition, motor passes to motor with power from the series connection vibration damper and passes to second motor again to the ransaxle vehicle by clutch again, some power of energy-storage system is directly passed to vehicle simultaneously, compare with conventional automobile, power has 2 covers, for power train itself, self-excited vibration is arranged, the transmission system part is many in addition, and rotary inertia own is big, needs vibration damper that better effectiveness in vibration suppression is arranged.Vibration damper will be protected power train (axle) simultaneously, and vibration damper should be better than coupling from the ability of structure protection axle.
The utility model is to be basic part with a common vibration damper, several damper disc assemblies of connecting then, constitute the series connection vibration damper, referring to Fig. 1, be the utility model series connection vibration damper torsion damping curve, from curve: windup-degree is a plurality of vibration damper angle sums (θ=θ 1+ θ 2+ .... θ n), rigidity be (R=R1 * R2 * ... ..Rn/ (R1+R2+ ... ..Rn)) compare with existing flywheel vibration damper and common single vibration damper, windup-degree increases, rigidity reduces, and has higher better effectiveness in vibration suppression.
The utlity model has simple in structure, low cost of manufacture (relatively flywheel vibration damper), stable work in work, torsion angle is big, rigidity is little, can effectively prolong the attack time, slows down impact, reduces vibration, and transmission system has been played good protection.
