Abstract
A kind of metal liner in leaf spring bushing, including press-in spring eye, metal liner are provided at both ends with packing ring, and packing ring is made of the nonmetallic materials with favorable elasticity and wearability, and cushion is located between stent and grasswort and metal liner.The Novel lining have it is simple in structure, manufacture it is of low cost, easy to assembly, available in large-tonnage leaf springs of car（Good reliability）, anti-wear excellent noise reduction effect the advantages that, there is prominent practicality.
Description
Technical field
A kind of leaf spring bushing is the utility model is related to, belongs to automotive suspension technical field.
Background technology
Existing leaf spring bushing generally use be " metal-rubber-metal " composite construction, inner liner metal casing
End face coordinates with dumb iron, and first grasswort of end face and leaf spring of outer lining metal sleeve coordinates, inner liner metal set
Rubber layer is provided between pipe and outer lining metal sleeve, rubber layer is integrated with the vulcanization of inside and outside metal sleeve.The leaf spring serves as a contrast
The shortcomings that set is：1st, compared with the bushing of all-metal, the bearing capacity of " metal to rubber " combined type bushing is limited, this structure
Bushing is not suitable in large-tonnage automobile leaf spring；2nd, the inner liner metal casing of this bushing must be set between stent
Fit-up gap, the excessive traveling light plate spring in gap can send abnormal sound, and gap is too small, can increase the manufacture cost of part, and
It is not easy to assemble on production line.
The content of the invention
The purpose of this utility model is the drawbacks described above for existing leaf spring bushing, there is provided a kind of simple in structure, system
Make it is of low cost, easy to assembly, available in large-tonnage leaf springs of car（Good reliability）, anti-wear excellent noise reduction effect steel plate bullet
Spring bushing, has prominent practicality.
To achieve the above object, the technical solution of the utility model is：
A kind of metal liner in leaf spring bushing, including press-in spring eye, the both ends of metal liner are set
There is packing ring, packing ring is made of the nonmetallic materials with favorable elasticity and wearability, and cushion is located at stent and grasswort and metal
Between bushing pipe.
Preferably, less gap or non-preset clearance, stent are reserved between packing ring and grasswort, metal liner and stent
The design gaps for gasket compression deformation are reserved between grasswort and metal liner.
Preferably, the inner wall of metal liner is equipped with oil leab.
Preferably, packing ring is the rubber with favorable elasticity and wearability.
Compared with prior art, the beneficial effects of the utility model are：
1. the utility model eliminates the weaker structure of the supportives such as rubber in the vertical gap of parts, steel is improved
The ability of the carrying vertical load of flat spring bushing, can adapt to the requirement of large-tonnage automobile leaf spring.
2. the utility model pads in the lateral clearance of parts and has set vibration-proof structure（Packing ring）, effectively reduce steel plate bullet
Frictional dissipation and noise between spring and stent.
3. the utility model overall structure is simple, has the advantages that to manufacture of low cost, easy to assembly, good reliability.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
In figure：Grasswort 1, metal liner 2, packing ring 3, stent 4.
Embodiment
Below in conjunction with brief description of the drawings, the utility model is further described in detail with specific embodiment.
Referring to Fig. 1, the metal liner 2 in a kind of leaf spring bushing, including press-in spring eye 1, metal liner 2
Be provided at both ends with packing ring 3, packing ring 3 is made of the nonmetallic materials with favorable elasticity and wearability, packing ring 3 pad be located at stent
Between 4 and grasswort 1 and metal liner 2, frictional dissipation and noise between leaf spring and stent can be effectively reduced.
As preferable technical solution, less gap is reserved between packing ring 3 and grasswort 1, metal liner 2 and stent 4
Or non-preset clearance, the design gaps for 3 compression of packing ring are reserved between stent 4 and grasswort 1 and metal liner 2.
As preferable technical solution, the inner wall of metal liner 2 is equipped with oil leab, reduces the friction of bushing pipe and fixed pin
Loss, prolongs the service life.
As preferable technical solution, packing ring 3 is the rubber with favorable elasticity and wearability.
Embodiment 1：
As shown in Figure 1, metal liner 2 and setting in a kind of leaf spring bushing, including press-in spring eye 1
Packing ring 3 in 2 both ends of metal liner, packing ring 3 are made of the rubber with favorable elasticity and wearability, and the pad of packing ring 3 is located at stent 4
Between grasswort 1 and metal liner 2, less gap or not is reserved between packing ring 3 and grasswort 1, metal liner 2 and stent 4
Preset clearance, is reserved with the design gaps for 3 compression of packing ring between stent 4 and grasswort 1 and metal liner 2, can effectively drop
Frictional dissipation and noise between low leaf spring and stent.The inner wall of metal liner 2 is equipped with oil leab, reduces bushing pipe and fixation
The frictional dissipation of pin, prolongs the service life.
Above content is to combine the further description that embodiment does the utility model, it is impossible to thinks this
The specific implementation of utility model is confined to these explanations, comes for the utility model person of an ordinary skill in the technical field
Say, without departing from the concept of the premise utility, the simple replacement made, should all be considered as belonging to the utility model
Protection domain.
