Description
Technical field
The present invention relates to automotive suspension technical field, the variation rigidity that specifically a kind of anti-side is turned round lacks leaf spring.
Background technology
The lightweight of automobile is not to reduce quality or plate thickness simply, can not simply be waited with the concept of loss of weight
Together.Automotive light weight technology is to reduce car body weight as much as possible on the basis of improving or improving comprehensive vehicle performance, reach quality
Reduction, structure optimization, security performance improve and cost reduction this organically combine target.
Few leaf spring is the leaf spring that the thin thick middle in both ends, wide isometric reed are stacked up.Same carrying, is used
Few leaf spring replaces multiple-leaf spring that can mitigate 20% or so of leaf spring dead weight；So under automotive light weight technology requirement, few leaf spring can be got over
To be more widely applied.
Traditional few leaf spring such as is all at the rigidity, and vehicle comfort is bad when empty wagons.Variation rigidity, which lacks leaf spring, can meet empty wagons
Comfortably, the requirement that full vehicle can carry.But the length that variation rigidity lacks each reed of leaf spring is substantially consistent with the action length of leaf spring, automobile
It is apparent to lack the dislocation of leaf spring end when driving on uneven road surface, to prevent leaf spring from being turned round in width direction side, usually in auxiliary spring on piece
Rivet clamp.Since the stroke of variation rigidity leaf spring is bigger, this requires clamp height and width will than etc. rigidity leaf spring
Clamp height is high, width is wide, this can occupy chassis space, while can interfere during the motion with tire, vehicle frame, influence automobile
Driving safety.
