A kind of new automobile electromotor protects solar or lunar halo assembly
Technical field
The present invention relates to the heat abstractor of automobile engine, specifically a kind of new automobile electromotor protects solar or lunar halo assembly.
Background technology
Existing protect solar or lunar halo and relevant assembly parts assembling signal as shown in accompanying drawing 1,2.Protecting solar or lunar halo 1 material and have metal and plastics bi-material, the existing steel plate materials of employing mostly realizes making, and concrete process is: blanking → round as a ball → shaping → welding → flange → punching → trimming.Radiator wind shelling cover 5 uses Shooting Technique to make, for working of plastics mostly.During assembling, it is first standard component by American this clip of larynx clip 2 and 4(, there is unidirectional slip locking function) it is enclosed within sealing ring 3 corresponding recesses, now clip is in " loose " state, sealing ring 3(diameter) small end is enclosed within and protects on solar or lunar halo 1, when sealing ring 3 with protect the laminating of solar or lunar halo 1 binding face after will tighten clip until sealing ring 3 with protect solar or lunar halo without relative displacement or rotation, will be fixed on and protect on solar or lunar halo 1 by sealing ring 3 small end;Then solar or lunar halo 1 and sealing ring 3 general assembly are protected by screw and nut in electromotor respective holder by assemble.Sealing ring 3(diameter) hold with the wind shelling cover 5(wind shelling cover assembled in advance on heat radiator assembly on a heat sink greatly) be connected by American larynx clip 4 and fix, equipment adjustment method is the same with small end clip.
Current this structure, by limitations and general assembly part cumulative errors, must be corrected American larynx clip 4 and sealing ring 3, cause assembly difficulty big during assembling, efficiency is low;American larynx clip 4 bonding strength is limited, easily loosen under the effect of vibration produced in car load driving process, sealing ring 3 sealing effectiveness is caused to be deteriorated, leak out the most serious, and produce noise in various degree, sealing ring 3 cold and heat succeed each other and under judder fatigue strength and fatigue limit all reduce, torsional deformation, tear damaged, service life shortens, and easily tears breakage.Interference and collision phenomenon is there is by limitations during protecting solar or lunar halo assembly rubber ring and radiator guard assembling.
Summary of the invention
The present invention is to solve that to protect solar or lunar halo assembly efficiency of assembling during actual entrucking low, the interference and collision existed by limitations and the low problem of the loaded down with trivial details production efficiency of sulfuration process, special propose a kind of new automobile electromotor and protect solar or lunar halo assembly.
The technical scheme is that for this, a kind of new automobile electromotor protects solar or lunar halo assembly, including protecting solar or lunar halo, it is characterized in that: be provided with open type pressure riveting structure on solar or lunar halo axle journal protecting, the rubber ring loading after-applied pressure of open type pressure riveting structure makes the opening of open type pressure riveting structure reduce clamping rubber ring formation and protects solar or lunar halo assembly, wherein rubber ring axially-extending, forms horn mouth.
Further it is improved by: the linkage section between axially-extending and the wind shelling cover of rubber ring is provided with abrupt changes in thickness structure, makes rubber ring to fold by free flange.
Further it is improved by: horn mouth opening angle a is 10 ° ~ 50 °.
Beneficial effect:
The present invention protects solar or lunar halo axle journal and is provided with open type pressure riveting structure structure, the rubber ring loading after-applied pressure of open type pressure riveting structure makes pressure riveting structure opening reduce clamping rubber ring formation and protects solar or lunar halo assembly, rubber ring axially-extending, form horn mouth, and the linkage section between the axially-extending and wind shelling cover of rubber ring is provided with abrupt changes in thickness structure, making rubber ring can be at free flange folded state, the axial dimension i.e. total length so protecting solar or lunar halo assembly significantly reduces.
During actual entrucking, protect solar or lunar halo assembly to be connected with engine support beforehand through screw and nut, solar or lunar halo assembly rubber part flange vertically will be protected the most again stretch, flange is just press-fitted in rubber ring on radiator wind shelling cover while stretching, and be fitted tightly on radiator air hood, so being possible not only to cancel two clips, technical process simplifies simultaneously, and greatly reduces problem that is big because of limitations assembly difficulty and that interfere.
Bell-mouthed setting is to adapt to the radiator wind shelling cover of different automobile types, do not only have demoulding effect, and during assembling, there is guide effect, so rubber seal and radiator wind shelling cover interference fit under the effect of rubber ring elasticity tension, rubber part is fitted tightly on radiator air hood, it is to make rubber ring to fold by free flange that linkage section between axially-extending and the wind shelling cover of rubber ring is provided with the effect of abrupt changes in thickness structure, so rubber ring axial overall length can reduce, protect solar or lunar halo assembly in car load assembling hoisting process, can avoid protecting the problem that solar or lunar halo assembly rubber ring and radiator guard are existed, by limitations, the assembling difficulty that interference and collision causes.

Detailed description of the invention
The present invention is as shown in Fig. 3,4,5,6,7,8.
A kind of new automobile electromotor protects solar or lunar halo assembly, including protecting solar or lunar halo 1, it is provided with open type pressure riveting structure 6 on solar or lunar halo 1 axle journal protecting, rubber ring 7 load the after-applied pressure of open type pressure riveting structure 6 make the opening of open type pressure riveting structure 6 reduce clamping rubber ring 7 formed protect solar or lunar halo assembly, wherein rubber ring 7 axially-extending, forms horn mouth.
Linkage section between axially-extending and the wind shelling cover 5 of rubber ring 7 is provided with abrupt changes in thickness structure 8, makes rubber ring 7 to fold by free flange.
Horn mouth opening angle a is 10 ° ~ 50 °.
