Abstract
The present invention relates to a kind of double mass flywheel, including arc spring, the double mass flywheel also vibration damper bar including arc, the vibration damper bar is inserted in the arc spring.The vibration damper bar in arc spring is inserted in, being capable of absorption resonance energy, reduction impulsive torque, so as to protect arc spring, it is to avoid the rapid wear of spring.
Description
Technical field
The present invention relates to double mass flywheel.
Background technology
In the prior art, double mass flywheel (DMF) is widely used to improve the NVH performances of automobile,
But meanwhile, resonance impulsive torque occurs when car is operated in below idling, cause drive disk assembly easy
Damage.According to model analysis, DMF resonant frequencies in 11Hz or so, when car is operated in below idling,
Meeting excitation resonance impulsive torque, is applied on the arc spring of double mass flywheel so that arc spring is easy
It is plastically deformed, it is fragile.
The content of the invention
The problem that the present invention is solved is that resonance impulsive torque is applied on arc spring and causes spring fragile
Problem.
To solve the above problems, the present invention provides a kind of double mass flywheel, including arc spring, described double
The mass flywheel also vibration damper bar including arc, the vibration damper bar is inserted in the arc spring.
Specifically, the vibration damper bar slide end correspondence be inserted in the arc spring slide end in, it is described
Have for supplying arc when torque is not applied between the drive end of the drive end of vibration damper bar and the arc spring
The distance of spring-compressed movement, in other words, there is the corner surplus of enough offer normal driving operating modes.
End tight fit is slided with the arc spring in the end of sliding of the vibration damper bar.
Diameter of the diameter for sliding end of the vibration damper bar slightly larger than drive end.
Compression angle of the corner of the vibration damper bar slightly larger than the arc spring under breakdown torque.In other words,
Maximum compression angle of the corner of the vibration damper bar slightly larger than the arc spring.
During specific implementation, the arc spring is the helical spring of arc.
Compared with prior art, technical scheme has advantages below：Vibration damper bar is inserted in arc bullet
In spring, being capable of absorption resonance energy, reduction impulsive torque, so as to protect arc spring, it is to avoid spring
Rapid wear.
Brief description of the drawings
Fig. 1 is the partial schematic diagram that vibration damper bar is inserted in arc spring in the present invention；
Fig. 2 is the partial schematic diagram of double mass flywheel of the present invention.
Specific embodiment
It is understandable to enable the above objects, features and advantages of the present invention to become apparent, below in conjunction with the accompanying drawings
Specific embodiment of the invention is described in detail.
A kind of double mass flywheel, including arc spring 1, arc vibration damper bar 2, vibration damper bar 2 is inserted in arc
In shape spring 1, as illustrated in fig. 1 and 2.Arc spring 1 is the helical spring of arc.Vibration damper bar 2
That slides that end correspondence is inserted in arc spring 1 slide end, and vibration damper bar slides end with arc spring
Slide end tight fit, the diameter for sliding end of arc spring and vibration damper bar slightly larger than the diameter of drive end,
So vibration damper bar can not be moved freely wherein, prevent from influenceing the dynamic balancing of DMF.The vibration damper bar 2
Corner does not influence the compression absorbing work(of arc spring thus slightly larger than the maximum compression angle of arc spring 1
Energy.There are enough offer normal drivings between the drive end of vibration damper bar 2 and the drive end of arc spring 1
The corner surplus of operating mode.The cross section of vibration damper bar 2 can be any shape, as long as arc spring can be inserted
Inside reach required intensity and durability.Vibration damper bar 2 is inserted in arc spring 1, being capable of absorption resonance energy
Amount, reduces impulsive torque, so as to protect arc spring, it is to avoid the rapid wear of spring.Arc need not so be changed
Shape spring, it is ensured that the normal function of DMF, also reduces cost.By the selection to vibration damping bar material,
So that vibration damper bar has preferable durability and mechanical performance.Vibration damper bar is set, moreover it is possible to reduce and ECU is supplied
The dependence of business's oil-break strategy, protects DMF.Further, the DMF with vibration damper bar can improve
Vehicle starting performance.
Although present disclosure is as above, the present invention is not limited to this.Any those skilled in the art,
Without departing from the spirit and scope of the present invention, can make various changes or modifications, therefore guarantor of the invention
Shield scope should be defined by claim limited range.
