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 utility model provides a kind of double mass flywheel that adopts land location two-stage spring, 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, one-level spring and the two-level spring of described elementary flywheel assembly position connection by spring land.
A kind of mode of execution of the utility model is that described one-level spring and two-level spring are the arc spring that Steel material is made.
A kind of mode of execution of the utility model is that described spring land is that Steel material is made.
A kind of mode of execution of the utility model is that interference is connected with spring land respectively for described one-level spring, two-level spring.
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, adopt land positioning two-stage spring to realize two stage stiffness, guaranteeing under the prerequisite of torque-transfer capability like this, it is lower that one-level rigidity just can arrange, can greatly improve the vibration damping capacity of double mass flywheel, land can connect into as a whole by one-level spring and two-level spring simultaneously, prevent from producing torsional deformation in moment of torsion transmittance process, further increase the run stability of double mass flywheel.
The utility model has the advantage of: novel structure, by land, locate after two-stage spring, one-level spring and two-level spring can effectively link together, can effectively prevent that inconsistent phenomenon from appearring in arc spring when reversing, increase the area of contact of one-level spring and two-level spring simultaneously, guaranteed the durability of spring.And reduce play in double mass flywheel annular chamber of one-level spring and two-level spring and produce impact noise.
