Between turbine.The main parts size of automobile torque converter, such as pump wheel assembly, guide wheel assembly, turbine assembly, cap assembly and is closed
Connection relationship between lock clutch assembly has specific record in existing document.
Car fluid torque-converter is after the assembly is completed, by the way that pump wheel assembly and cap assembly to be welded together.It adopts at present
Welding manner is that carbon dioxide and argon gas mixed gas arc welding connect, due to welding in the fit-up gap of pump impeller and lid
For spatter possibly into fluid torque-converter inside, polluting leads to torque-converters operational failure inside torque-converters in the process.
Summary of the invention
The purpose of the invention patent is the technical issues of solution because of pollution torque-converters interior welds pollution.
To realize the present invention patent purpose and the technical solution adopted is that such, a kind of band prevents welding pollution structure
Fluid torque-converter, including the pump wheel assembly snapped together by seam allowance and cap assembly, the pump wheel assembly and cap assembly phase
The seam allowance of fastening is male half coupling, and the seam allowance that the cap assembly is interlocked with pump wheel assembly is concave mouth.It is cased on the male half coupling
One becket has annular groove between the becket and male half coupling step surface.
When the concave mouth of cap assembly fastens, concave mouth end face compresses becket, makes pump wheel assembly and lid total by welding
At linking into an integrated entity.
Further, the shaft section of the becket is rectangle.The becket it is axial with a thickness of L1.The annular groove
Width is L2.L1=0.125 × L2~0.28 × L2.
The distance of becket to male half coupling end face is L4, and the distance of the concave mouth end face to concave mouth step is L3, L3
< L4.
Further, the becket and the male half coupling of pump wheel assembly are integrally formed by Vehicle Processing.
The course of work of the invention patent: after assembly of hydraulic torque converter has assembled, becket on pump impeller shell seam allowance with
The seam allowance end face of cap assembly shell is tightly bonded, and plays certain sealing function, prevents the splashing etc. of welding when assembly welds
Pollutant, which enters inside torque-converters, pollutes torque-converters.
The novel main effect of the present invention is: by changing the structure at pump wheel assembly and cap assembly cooperation, can prevent
When assembly welds, some dust or particle enter inside fluid torque-converter, pollute.
In the novel automobile torque converter that can be widely applied to need to carry out assembly welding of the present invention.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of existing automobile converter coupling；
The partial enlarged view of L portion in Fig. 2 Fig. 1；
Fig. 3 is that the novel pump wheel assembly of the present invention and cap assembly assemble stop portion schematic diagram.
In figure: pump wheel assembly 1；Guide wheel assembly 2；First thrust bearing 3, the second thrust bearing 4；Turbine assembly 5；Be latched from
Clutch assembly 6；Cap assembly 7；Weld seam 8；Improved pump wheel assembly 9；Concave mouth end face 701；Concave mouth step 702；Becket
901；Annular groove 902；Male half coupling step surface 903；Male half coupling end face 904.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples, but should not be construed the above-mentioned theme of the present invention
Range is only limitted to following embodiments.Without departing from the idea case in the present invention described above, known according to ordinary skill
Knowledge and customary means, make various replacements and change, should all include within the scope of the present invention.
It is existing fluid torque-converter in figure referring to Fig. 1 and 2.By pump wheel assembly 1；Guide wheel assembly 2；First thrust bearing
3, the components such as the second thrust bearing 4, turbine assembly 5, lockup clutch assembly 6 and cap assembly 7 are constituted.The pump impeller of the device is total
It is weld seam 8 at 1 and 7 junction of cap assembly.During the formation of weld seam 8, it is difficult to avoid pollution object and enter pump wheel assembly 1 and lid
The inside for the shell that assembly 7 forms.
A kind of band prevents the fluid torque-converter of welding pollution structure, including the pump wheel assembly 1 snapped together by seam allowance
With guide wheel assembly 2, the seam allowance that the pump wheel assembly 1 is interlocked with cap assembly 7 is male half coupling, the cap assembly 7 and pump wheel assembly 1
