Abstract
The utility model discloses a kind of loading machine fixed axle gearbox clutch retraction springs to assemble device, including clutch drum body, piston component, return spring, baffle ring, limit circlip, tapered sleeve, sleeve and clutch shaft;Clutch drum body and clutch shaft pass through welded connecting;Piston component is assemblied in clutch drum body;Return spring is covered on clutch shaft and is contacted with piston component end face;Baffle ring is covered on clutch shaft and is contacted with return spring end face;Tapered sleeve covers on clutch shaft, and large end face is contacted with the shaft shoulder of clutch shaft;Limit circlip is inserted in tapered sleeve small end before assembly, plays position-limiting action to baffle ring after assembly;Sleeve penetrates clutch shaft, and contacts with limit circlip.The utility model structure is simple, production is low with maintenance cost, safe and reliable, solve the problems, such as in the prior art because return spring line footpath is big, rigidity causes by force assembly difficulty, low efficiency and can not will limit circlip disposably assemble and cause remaining parts repeatedly to assemble in place due to there are damage parts.
Description
Technical field
The utility model relates to loading machine fixed axle gearbox clutch packs, and in particular to and return spring assembles device,
In particular to 3 tons of wheel loader fixed axle gearbox clutch retraction springs assemble device.
Background technique
The 3 tons of wheel loaders in the country generally use fixed axle gearbox at present, mainly by various gears in the type gearbox
Clutch pack composition realizes the switching of gearbox gear by the movement of clutch pack inner piston.In clutch pack
Return spring switches vital effect to gear, and when switching gear, return spring should be able to rapidly be returned piston
Position avoids the occurrence of gear interference, switches gear accurately, without impact.But due to generalling use time that line footpath is big, rigidity is strong at present
Position spring, enabling is to ensure that the limit circlip of return spring assembles in place in assembling process, it has to using biggish
Dynamics, and can not disposably assemble in place, assembly difficulty is very big, and repeatedly assembles the damage for be easy to causeing remaining parts, especially
When being after-sales service, due to place, the limitation of tool, the problem of assembly difficulty is big, low efficiency, is more prominent.
Summary of the invention
The purpose of the utility model is to overcome drawbacks described above, provide that a kind of structure is simple, production is low with maintenance cost, uses
Safe and reliable loading machine fixed axle gearbox clutch retraction springs assemble device, solve in the prior art because of loading machine dead axle
Return spring line footpath is big in formula speed change box clutch component, rigidity is strong, causes assembly difficulty, low efficiency, and can not be by limiting card
Spring disposably assembles in place, and remaining parts is caused repeatedly to assemble and the problem of damage parts occur.
In order to achieve the above object, the utility model loading machine fixed axle gearbox clutch retraction springs assembly device includes
Clutch drum body, piston component, return spring, baffle ring, limit circlip, tapered sleeve, sleeve and clutch shaft;The clutch drum body
Pass through welded connecting with clutch shaft;The piston component is assemblied in clutch drum body;The return spring is covered in clutch
It is contacted on axis and with piston component end face;The baffle ring is covered on clutch shaft and is contacted with return spring end face;The tapered sleeve
It covers on clutch shaft, large end face is contacted with the shaft shoulder of clutch shaft;The limit circlip is inserted in tapered sleeve in the pre-assembly
Small end, assembly play position-limiting action to baffle ring afterwards in place;The sleeve penetrates clutch shaft, and contacts with limit circlip.
Above-mentioned loading machine fixed axle gearbox clutch retraction springs assembly device is by being placed on clutch shaft for tapered sleeve
Interior, large end face is contacted with the shaft shoulder of clutch shaft, and limit circlip is placed on tapered sleeve small end, then sleeve is inserted in clutch shaft
On, contact it with limit circlip end face.In assembling process, by firmly tapping sleeve end face, sleeve is by return spring pressure
Contracting, while limit circlip gradually being swollen along tapered sleeve internal diameter, it, disposably will limit circlip dress by the inertia of percussion, impact
With the assembly in place, realizing return spring, have following technical characterstic and the utility model has the advantages that
1, clutch retraction springs assembly device only needs two kinds of tool parts, easy to carry, and structure is simple, practical, efficiency
Height can greatly improve the assembly efficiency and after-sales service efficiency of speed change box clutch component;
2, device is assembled using the clutch retraction springs of the structure, can disposably guarantees return spring assembly in place,
Avoid damage parts caused by repeatedly assembling, save the cost.
The utility model loading machine fixed axle gearbox clutch retraction springs assembly device only needs two kinds of tool parts, ties
Structure is simple, practical, high-efficient, easy to carry, can greatly improve the assembly efficiency and after-sales service of speed change box clutch component
Efficiency, solves in prior art central-axis type speed change box clutch component that return spring line footpath is big, rigidity is strong, causes assembly tired
The problem of difficult, low efficiency, and can not disposably assembling in place, the damage parts for causing remaining parts to occur because repeatedly assembling.
Detailed description of the invention
Fig. 1 is the utility model loading machine fixed axle gearbox clutch retraction springs assembly device main cross-sectional schematic diagram.
Appended drawing reference: clutch drum body 1, piston component 2, return spring 3, baffle ring 4, limit circlip 5, tapered sleeve 6, sleeve 7,
Clutch shaft 8.
Specific embodiment
With reference to the accompanying drawings and detailed description to the utility model loading machine fixed axle gearbox clutch retraction bullet
Spring assembly device is described in further detail.
Shown in Fig. 1, it includes clutch that the utility model loading machine fixed axle gearbox clutch retraction springs, which assemble device,
Drum body 1, piston component 2, return spring 3, baffle ring 4, limit circlip 5, tapered sleeve 6, sleeve 7 and clutch shaft 8;The clutch drum
Body 1 and clutch shaft 8 pass through welded connecting;The piston component 2 is assemblied in clutch drum body 1;3 sets of the return spring exists
It is contacted on clutch shaft 8 and with 2 end face of piston component;4 sets of the baffle ring connects on clutch shaft 8 and with 3 end face of return spring
Touching;On clutch shaft 8, large end face contacts 6 sets of the tapered sleeve with the shaft shoulder of clutch shaft 8;The limit circlip 5 is assembling
It is inserted in the small end of tapered sleeve 6 before, assembly plays position-limiting action to baffle ring 4 afterwards in place;The sleeve 7 penetrates clutch shaft 8, and with limit
Position circlip 5 contacts.
In assembly, by firmly tapping 7 end face of sleeve, sleeve 7 compresses return spring 3, while will limit 5 edge of circlip
Tapered sleeve 6, internal diameter gradually swells, by the inertia of percussion, impact, disposably will limit circlip 5 assembly in place, realize return bullet
The assembly of spring 3.
This clutch retraction springs assembles device, is able to solve return spring line in existing shaft type speed change box clutch component
Diameter is big, rigidity is strong, causes assembly difficulty, low efficiency, and can not disposably assemble in place, causes remaining parts due to repeatedly assembling
The problem of damage parts of appearance;The present apparatus only needs two kinds of tool parts, and structure is simple, practical, high-efficient, can greatly improve
The assembly efficiency and after-sales service efficiency of speed change box clutch component.
