Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The purpose of the utility model is to provide the connection structures of a kind of outer barrel of absorber and spring holder, match by using interference
The connection type of conjunction makes the connection structure that fastening is formed between spring holder and outer cylinder, and it is convenient to assemble, and component structural is simple, section
About cost improves working efficiency, extends the working life of damper.
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing and have
Body embodiment is described in further detail the utility model.
The present embodiment provides the connection structures of a kind of outer barrel of absorber and spring holder, as shown in Figure 1-3, include outer cylinder 1 and
Spring holder 2, wherein outer cylinder 1 is equipped with the protrusion 3 for being used to support spring holder, and 3 top of protrusion is additionally provided with step 4, spring holder 2 and platform
Rank 4 is interference fitted, and raised 3 pairs of spring holders 2 play a supportive role, to realize that spring holder 2 and the interference of outer cylinder 1 are connect.
The setting of 4 outer diameter of step is 1mm~1.5mm bigger than 1 outer diameter of outer cylinder, and the outer diameter that 2 internal diameter of spring holder is greater than outer cylinder 1 is small simultaneously
In the outer diameter of step 4, to realize the interference fit of spring holder 2 Yu step 4.Specifically, the interference between spring holder 2 and step 4
Amount is 0.2mm~0.3mm.The reason of using this range magnitude of interference are as follows: if magnitude of interference is less than 0.2mm, spring holder 2 and 4 bullet of step
Property pressure is too small, can not achieve relatively reliable interference fit；If magnitude of interference is greater than 0.3mm, spring holder 2 is not easy to fill with outer cylinder 1
Match, even if assembling by force, be also easy to be deformed outer cylinder 1, or spring holder 2 is made to generate cracking, leads to defective shock absorber.
Further, protrusion 3 is arc.Specifically, the radius of protrusion 3 is 4mm~6mm, using the original of this range radius
Cause are as follows: if the radius of protrusion 3 is less than 4mm, protrusion 3 is less with the contact area of spring holder 2, and raised 3 forced areas are small, vibration damping
When the spring of device generates impact to spring holder 2 downwards, slipping phenomenon easily occurs between spring holder 2 and protrusion 3；If the half of protrusion 3
Diameter is greater than 6mm, then bearing strength reduces at protrusion 3, and the spring of damper easily leads to outer cylinder when generating impact to spring holder 2 downwards
1 deformation, makes defective shock absorber.
Further, to make protrusion 3 preferably realize the supporting role to spring holder 2,2 lower part of spring holder is equipped with flange circle
Arc is fitted closely with the transition arc of 3 top of protrusion.Specifically, the radius of 2 lower part flange circular arc of spring holder be set as 2mm~
4mm, the radius of raised 3 top transition arcs are also set as 2mm~4mm, and when assembly is between the two to be fitted closely.Meanwhile protrusion 3
Lower section also is provided with transition arc, and specifically, radius is set as 10mm~12mm, to realize effective branch of raised 3 pairs of spring holders 2
Support prevents protrusion 3 from deforming.
Further, to make to be easier to assemble between spring holder 3 and step 4, the top of step 4 is equipped with guide part.Specifically,
Guide part is inclined-plane, is assembled convenient for spring holder 2 on step 4.Further, for make interference connect more reliable, length of bench
It is set as 10mm~15mm.
Further, the quantity of protrusion 3 is multiple.Specifically, raised 3 quantity can be set as 3,4,5 or other can
The quantity effectively supported is formed to spring holder 2.
The connection structure of outer barrel of absorber provided by the utility model and spring holder, using the connection type of interference fit,
Make the connection structure for forming fastening between spring holder and outer cylinder, is used between outer barrel of absorber and spring holder compared to the prior art
Welding structure, eliminate welding seam breaking generation security risk, interference connection structure assembly it is convenient, component structural letter
Single, save the cost improves working efficiency, while can effectively extend the working life of damper.
The utility model applies specific case and is expounded to the principles of the present invention and embodiment, the above reality
The explanation for applying example is merely used to help understand the method and its core concept of the utility model；Meanwhile for the general of this field
Technical staff, based on the idea of the present invention, there will be changes in the specific implementation manner and application range.To sum up,
The content of the present specification should not be construed as a limitation of the present invention.
