Description
Technical field
The present invention relates to a kind of press-loading devices of arc cluster spring, more particularly to a kind of two arc springs to be assembled
When the press-loading device that uses.
Background technique
Spring it is commonly used, make spring structure present diversification, wherein largely use one in automobile dual-mass flywheel
Kind arc spring.With the promotion of engine power, single-arc shaped damping spring has been unable to satisfy technical requirements, while different
Driving condition needs corresponding spring rate, and inside and outside cluster spring can provide solution regarding to the issue above.Outer spring mentions
For primary rigidity, engine start, low speed segment rigidity requirement can be met, high regime is acted on simultaneously by inside and outside cluster spring.Arc
The difference of spring and other straight springs is that the pitch in spring between outside is inconsistent, unstable so as to cause spring surface stress
Fixed, inside is big, and outside is small.The working environment of arc spring is severe, and stress is unstable, compared to being more easily broken off for straight spring.
Especially inner spring must be fixed with outer spring and connect reliably, if inner spring is not fixed firmly slide-in outer spring
It is interior, then the a-circle-by-a-circle gap of outer spring is easily squeezed into, thus the fracture of acceleration spring.The connection side of outer spring and inner spring at present
Formula generallys use the scheme for playing lid connection in industry.In this kind of connecting mode, since the position of lid connecting spring is interference
Cooperation, therefore having static and dynamic stress, defect in the process of running is easy in this regional fracture.Meanwhile lid is installed
Additional machine and tooling are needed, which increases activity times and manufacturing cost.
