Description
Technical field
The present invention relates to leaf spring technical fields, more particularly to a kind of noise reduction piece and leaf spring for leaf spring.
Background technology
Leaf spring is current domestic commercial vehicle suspension system primary resilient element, generally several springs by being overlapped mutually
Steel plate forms, and when automobile encounters greater impact under steam, the transverse horizontal changing of the relative positions easily occurs for steel spring plate.Each bullet in order to prevent
Lateral horizontal position dislocation, each steel spring plate of leaf spring occurs between each spring leaf when after reed assembling and in vehicle traveling
Centre is fixed using U bolt, and both ends are connected and fastened using clamp.But normal direction collides between each spring leaf, simultaneously
It is longitudinal to rub, it will usually to send out Abnormal Sound, cause noise pollution, for the new energy vehicle of high-quality, noise is especially
It is prominent, become one of quality problem.
And the effect of leaf spring noise reduction piece is exactly to be in direct contact between avoiding plate spring sheet, or pass through rubbing between reduction plate spring sheet
Power is wiped to inhibit the raising of rigidity of plate spring.In order to preferably reduce the friction between plate spring sheet while the vibration that decays, noise reduction piece is multi-purpose
Rubber material is made.In use due to leaf spring, longitudinally, laterally with generation in normal orientation with respect to fortune between partition
Dynamic, therefore, leaf spring noise reduction piece acts on using process and often generates friction between end face and leaf spring face, cause to wear, cause
Its service life declines.
Invention content
It is an object of the present invention to provide a kind of noise reduction piece for leaf spring, to solve in the prior art without Metal Substrate
Rubber bodies are cut when the noise reduction piece of plate laterally or longitudinally moves between reed, rubber contact surface longitudinal move distance is larger, rubs
Wear lose it is more, cause noise reduction piece quick abrasion, short life defect.
A further object of the invention be solve due on leaf spring through-hole edge generate vertical impact power, pair with
The problem of its noise reduction piece contacted generates die cut, the noise reduction piece service life is caused to decline.
Another purpose of the invention is to provide for a kind of leaf spring, to solve the number of openings of reed end in the prior art
It is more, cause the problem that reed processing technology is more, reed intensity is low.
On the one hand, the present invention provides a kind of noise reduction pieces for leaf spring, are fixed on the two neighboring reed of the leaf spring
Between, including：
Rubber pad along its thickness direction there is opposite the first face and the second face, second face to be equipped with outwardly convex
Convex block；
The metal substrate for covering and being fixed on second face which is provided with one and be nested in the convex block outer surface
Boss；
Wherein, the boss is embedded into the mounting hole on the reed adjacent with the metal substrate, so that the metal
The surface of being on one side close to the reed of the substrate far from the rubber pad.
Optionally, the rubber pad is together with the metal substrate bonding by Vulcanization.
Optionally, the boss is kidney-shaped boss.
Optionally, the thickness of the rubber pad is 1~2mm.
Optionally, the thickness of the metal substrate is 3~6mm.
On the other hand, the present invention also provides a kind of leaf springs, including：
Leaf spring ontology comprising upper reed plate, intermediate reed and lower reed, between the upper reed plate and the intermediate reed,
And it is equipped with above-mentioned noise reduction piece between the intermediate reed and the lower reed.
Optionally, it is upper noise reduction piece to be set between the upper reed plate and the intermediate reed；
It is lower noise reduction piece to be set between the intermediate reed and the lower reed；
The upper noise reduction piece and the lower noise reduction piece are symmetrically disposed on the end of the leaf spring ontology along the intermediate reed
End.
Optionally, the end of the intermediate reed offers the boss for fixing the upper noise reduction piece and the lower noise reduction
The upper noise reduction piece and the lower noise reduction piece are symmetrically arranged on the through hole by the through-hole of the boss of piece.
Optionally, further include locking device, be configured to the convex of the boss of the upper noise reduction piece and the lower noise reduction piece
Platform is connected in a manner of it can unlock.
Optionally, the bolt being set on the lower noise reduction piece boss；With
The nut being set in the upper noise reduction piece convex block；
Wherein, the bolt passes through the boss of the upper noise reduction piece to support to positioned at described along the lower noise reduction piece thickness direction
Nut bore in upper noise reduction piece convex block coordinates with the nut the upper noise reduction piece and the lower noise reduction piece to be connect.
The noise reduction piece for leaf spring of the present invention, since noise reduction piece is the bilayer that rubber pad and metal substrate are secured together
The one side of structure, rubber pad is fixed on metallic substrates, the another side and switch jaw contact of rubber pad, in horizontal and vertical impact
In, only metal substrate contacted with the through-hole on reed, stress, reduce rubber pad contact surface fricting movement and tear transport
It is dynamic；Meanwhile the convex block of outwardly convex is nested in the boss of metal substrate on rubber pad, and it is opposing stationary with metal substrate, it avoids
Mounting hole die cut rubber pad increases making for noise reduction piece and leaf spring to improve the anti-shear ability of rubber pad all directions
Use the service life.
Further, due to opening up through-hole in intermediate reed, upper noise reduction piece and lower noise reduction piece are symmetrically arranged on through-hole
Place, to reduce the number of openings of reed, increases its service life, while reducing cost.
