Abstract
The utility mode relates to a dual mass flywheel with springs connected in series, and belongs to the technical field of automobiles. The dual mass flywheel with the springs connected in series comprises a primary flywheel assembly and a secondary flywheel assembly matched with the primary flywheel assembly. A first-level spring and a second-level spring in the primary flywheel assembly are connected in series and are arc-shaped springs made of steel materials, and the spring wire diameter and the number of active turns of the first-level spring are different from that of the second-level spring. The dual mass flywheel with the springs connected in series has the advantages that the structure is novel, the mode of arc-shaped springs connected in series is adopted, the connecting mode of the structure is simple and reliable, the two-stage rigidity is achieved, and the cost is reduced greatly compared with the two-stage rigidity of a traditional mode of arc-shaped springs connected in a concentric type; the arc of the springs is quite low, the process difficulty is reduced, the weight of the overall spring system is reduced greatly as well, the cost is reduced greatly, and the performance of the dual mass flywheel is improved greatly.
Description
Technical field
The utility model belongs to automobile technical field, particularly a kind of double mass flywheel.
Background technique
So-called double mass flywheel, is divided into two parts by an original flywheel: a part is retained in a side of original motor, plays the effect of original flywheel exactly, and for starting and transmit the driving torque of motor, this part is called elementary flywheel assembly; Another part is arranged on speed changer one side of transmission system, and for improving the rotary inertia of speed changer, this part is called secondary flywheel assembly.Between elementary flywheel assembly and secondary flywheel assembly, form a ring-like oil pocket, torsional vibration damper is housed in oil pocket.Torsional vibration damper is connected as a whole by elementary flywheel assembly with secondary flywheel assembly.Can effectively the decay torsional vibration of power transmission system of double mass flywheel, has reduced the natural frequencies of car transmissions, has extended the working life of each component in car transmissions, has improved the travelling comfort that automobile is taken simultaneously.
Obviously, double mass flywheel has played vital effect in the power transmission system of automobile, therefore, higher to the quality requirement of double mass flywheel.And most important component are arc spring in double mass flywheel, its manufacture cost is higher, also higher to the requirement of its precision and performance.Traditional arc spring in parallel is by parallel use after the arc spring concentric fits of two large radians, form two stage stiffness, because the radian of spring is larger, so manufacturing process is loaded down with trivial details, low precision and reliability low, cost also increases thereupon, in addition, traditional spring in parallel has caused the spring weight of whole spring system excessive, in actual High Rotation Speed process, can produce larger centrifugal force, increase the frictional force that is unfavorable for double mass flywheel vibration damping.
Summary of the invention
The double mass flywheel that the utility model provides a kind of spring to adopt serial fashion to connect, to solve, existing arc spring manufacturing process in parallel is loaded down with trivial details, low precision, weight are large, friction energetically, and reliability is low, the problem that cost is high.
The technological scheme that the utility model is taked is:
Comprise elementary flywheel assembly and the secondary flywheel assembly coordinating with described elementary flywheel assembly, the one-level spring in described elementary flywheel assembly adopts serial fashion to be connected with two-level spring.
Preferably, described one-level spring and two-level spring are the arc spring that Steel material is made.
Preferably, spring filament diameter, the number of active coils of described one-level spring and two-level spring are different.
Under the different driving cycle of car load, need double mass flywheel to there is different torsional stiffness characteristics, in the low moment of torsion stage, in order to reach more efficient vibration-damping effect, need lower rigidity, in view of this, the utility model provides a kind of double mass flywheel, adopts serial fashion to realize two stage stiffness, guaranteeing under the prerequisite of torque-transfer capability, it is lower that one-level rigidity just can arrange, and can greatly improve the vibration damping capacity of double mass flywheel, can reduce costs to greatest extent simultaneously.
The utility model has the advantage of: novel structure, the double mass flywheel that adopts series connection arc spring mode to connect, the Placement of this kind of structure is simple and reliable, has realized two stage stiffness, compares and greatly reduces cost with traditional arc spring concentric type two stage stiffness.Because spring radian is less, reduced technology difficulty, alleviated greatly the weight of whole spring system simultaneously, from cost and double mass flywheel performance, all obtained great lifting.
