Description
Technical field
The utility model relates to a kind of cylinders, and in particular to a kind of AMT range gear air cylinder.
Background technique
With the continuous increase of commercial vehicle ownership, heavy-duty commercial vehicle automatic mechanical type gearbox (hereinafter referred to as AMT) In
Accounting in the market is continuously increased.Requirement to AMT reliability is also continuously increased.Odd-side range gear air cylinder is that AMT realizes automatic
The important component of gearshift function is, it can be achieved that the high and low shift of AMT switches.
At present there are two types of range gear air cylinders used by commercial vehicle AMT, a kind of range gear air cylinder for full cast iron, this kind of gas
Cylinder uses casting process, and cost is relatively low, but this kind of cylinder uses in the excessively high area of moisture content, is easy to appear corrosion, causes
Shift clamping stagnation.Another kind is all aluminium alloy cylinder, although this kind of cylinder can be strong due to aluminium alloy to avoid corrosion problem
Degree problem needs to take die-casting process and surface shot blasting process, nonetheless, also easily occurs colliding with and leading in disassembly process
It causes cylinder seal performance to reduce, and then causes shift unhappy.
Summary of the invention
In order to solve the technical issues of existing ATM range gear air cylinder is easy to appear corrosion or collides with and lead to cylinder clamping stagnation,
The utility model provides a kind of AMT range gear air cylinder.
The technical solution of the utility model is:
A kind of AMT range gear air cylinder, including cylinder body, cylinder sleeve, piston, shift fork axle, cylinder cap；
The cylinder body is nested with cylinder sleeve；The setting piston in cylinder sleeve, shift fork axle one end connect piston, and the other end stretches out cylinder
For connecting shift fork after body；The shift fork axle and the piston coaxial are arranged.The cylinder cap is arranged in the end of the cylinder body.It is described
Cylinder body uses aluminium alloy；The cylinder sleeve uses gray iron.
Further, more convenient in order to process, the cylinder body and cylinder sleeve form integral piece by casting mode.
Further, for the ease of casting, and production cost is reduced, shortens the production cycle, the cylinder body uses ZL101A
Aluminium alloy.
Further, in order to improve product hardness, maintenance difficulty is reduced, the cylinder sleeve uses HT250.
Further, more convenient in order to install, the cylinder body is bolted with the cylinder cap.
The beneficial effect of the utility model compared with prior art is:
1, the cylinder body of the utility model uses aluminium alloy, and raw material cost is low, and corrosion resistance is good；Cylinder sleeve uses gray iron, firmly
Degree is high, and wearability is good, it is ensured that cylinder does not deform in disassembly process, reduces maintenance difficulty, improves the resistance to of product
Use performance.
2, the utility model effectively extends the use scope of AMT product, enhances the reliability of product.
3, cylinder sleeve is embedded in cylinder interior in casting process by the utility model, forms integral piece with cylinder body, processing is more
It is convenient.
4, the cylinder body in the utility model is not easy to form subcutaneous gas relative to die casting using ZL101A aluminium alloy convenient for casting
Hole, it is at low cost relative to low pressure casting convenient for machining, it is with short production cycle.
5, the cylinder sleeve in the utility model uses HT250, and Brinell hardness can reach HB270, it is ensured that disassembly process
Middle cylinder sleeve 2 does not deform, and reduces maintenance difficulty.
6, the cylinder body in the utility model and cylinder cap are bolted, and installation is more convenient.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model one embodiment；
Appended drawing reference in figure are as follows: 1- cylinder body, the first air inlet of 101-, the second air inlet of 102-, 2- cylinder sleeve, 3- piston, 4-
Shift fork axle, 5- end cap.
Specific embodiment
The utility model is further described below in conjunction with drawings and the specific embodiments.
Referring to Fig.1, which includes cylinder body 1, cylinder sleeve 2, piston 3, shift fork axle 4, cylinder cap 5.
Cylinder body 1 is nested with cylinder sleeve 2, and piston 3 is arranged in cylinder sleeve 2.4 one end of shift fork axle connects piston 3, and the other end stretches out cylinder body
For connecting shift fork after 1；Shift fork axle 4 and piston 3 are coaxially disposed.Cylinder cap 5 is bolted in the end of cylinder body 1.Cylinder body 1 passes through
Casting production, materials'use ZL101A, raw material cost is low, and is not easy to form subcutaneous blowhole relative to die casting, convenient for machining,
It is at low cost relative to low pressure casting, it is with short production cycle.Cylinder sleeve 2 is embedded in inside cylinder body 1 in casting process, forms one with cylinder body 1
Body part, because cylinder body 1 is avoided and formed in iron and carbon so that air intake duct and 5 contact surface of cylinder cap will not get rusty using ZL101A material
When primary battery, ion concentration is increased due to there is iron rust, enhances electric conductivity, the case where corrosion of iron is accelerated, to extend
The service life of cylinder, the user experience is improved.Cylinder sleeve 2 uses HT250 material, and Brinell hardness can reach HB270, can be with
Guarantee that cylinder sleeve 2 does not deform in disassembly process, reduces maintenance difficulty.
In use, first the first air inlet 101 of the cylinder and the second air inlet 102 are connect with gas source respectively.When second
When air inlet 102 is connected with source of the gas, piston 3 drives shift fork axle 4 to move axially along cylinder, and shift fork axle 4 is stretched out；When the first air inlet
101 when being connected with source of the gas, and piston 3 drives shift fork axle 4 axially to move backward along cylinder, and shift fork axle 4 is withdrawn.Shift fork axle 4 is along cylinder
Axially extended or retraction drives shift fork thereon to complete shift.
The above description is only the embodiments of the present invention, is not intended to limit the scope of the present invention, all benefits
The equivalent structure transformation made by the utility model specification and accompanying drawing content is applied directly or indirectly in other relevant skills
Art field, is included in the scope of patent protection of the utility model.
