Description
Technical field
The utility model relates to technical field of automobile, has been specifically related to a kind of turbosupercharger nozzle ring capable of changing cross sections.
Background technique
Turbosupercharger nozzle ring capable of changing cross sections is now in order to increase fixing soundness, adopt riveting method as the mode be connected and fixed, the shifting disc of turbosupercharger nozzle ring capable of changing cross sections is caused to need multiple auxiliary member just can complete location, and the area of contact between shifting disc and auxiliary member is larger, the torsion that when causing shifting disc to rotate, needs are larger, shifting disc reaction is insensitive, causes the power-lift speed of turbosupercharger slower; And the rotating driving device of turbosupercharger nozzle ring capable of changing cross sections after long-term use, the driver part of rotating driving device can wear and tear, if the driver part of rotating driving device is changed not in time, due to turbosupercharger nozzle ring capable of changing cross sections self infinite place function, rotating driving device excessively will oppress blade, make blade impaired, need when blade damage is serious to change nozzle ring capable of changing cross sections, take a lot of work and mistake.
Model utility content
For solving the problems of the technologies described above, we have proposed a kind of turbosupercharger nozzle ring capable of changing cross sections, its object: reduce the area of contact between shifting disc and auxiliary member, strengthen the limit function of self.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of turbosupercharger nozzle ring capable of changing cross sections, comprise blade weld assembly, spacer sleeve, roller, position limit pin, backing plate, socket head screw, shifting disc, initiatively shift fork and blade, blade weld assembly is provided with through hole and the counter sink corresponding to socket head screw, blade is welded with connecting rod, and connecting rod one end is riveted with one end of active shift fork through the through hole of blade weld assembly;
Socket head screw connects with spacer sleeve and backing plate spiral shell successively through the counter sink of blade weld assembly;
Position limit pin assigns in the inner hexagonal hole on socket head screw, and roller rotates the top being installed in position limit pin, and shifting disc is socketed on roller;
Be provided with draw-in groove inside shifting disc, initiatively the other end of shift fork assigns in described draw-in groove.
Preferably, the quantity of roller and position limit pin is three.
By technique scheme, position limit pin can limit the range of deflection of initiatively shift fork, prevents the situation occurring excessively compressing blade, enhances the limit function of self; Shifting disc is socketed on roller, reduces the area of contact between shifting disc and auxiliary member, enhances the sensitivity of shifting disc reaction.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the decomposition texture schematic diagram of a kind of turbosupercharger nozzle ring capable of changing cross sections disclosed in the utility model.
Numeral and the corresponding part title represented by letter in figure:
1. blade weld assembly 11. counter sink 2. spacer sleeve 3. roller 4. position limit pin 5. backing plate 6. socket head screw 7. shifting disc 71. draw-in groove 8. initiatively shift fork 9. blade.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with schematic diagram, embodiment of the present utility model is described in further detail.
As shown in Figure 1, a kind of turbosupercharger nozzle ring capable of changing cross sections, comprise blade weld assembly 1, spacer sleeve 2, roller 3, position limit pin 4, backing plate 5, socket head screw 6, shifting disc 7, initiatively shift fork 8 and blade 9, blade weld assembly 1 is provided with through hole and the counter sink 11 corresponding to socket head screw 6, blade 9 is welded with connecting rod, and connecting rod one end is riveted with one end of active shift fork 8 through the through hole of blade weld assembly 1.
Socket head screw 6 connects with spacer sleeve 2 and backing plate 5 spiral shell successively through the counter sink 11 of blade weld assembly 1.
Position limit pin 4 assigns in the inner hexagonal hole on socket head screw 6, and position limit pin 4 can limit the range of deflection of initiatively shift fork 8, prevents the situation occurring excessively compressing blade 9, enhances the limit function of self.
Roller 3 rotates the top being installed in position limit pin 4, and shifting disc 7 is socketed on roller 3, reduces the area of contact between shifting disc 7 and auxiliary member, enhances the sensitivity that shifting disc 7 reacts.
Be provided with draw-in groove 71 inside shifting disc 7, initiatively the other end of shift fork 8 assigns in described draw-in groove 71.
The quantity of roller 3 and position limit pin 4 is three, ensure that the stability that shifting disc 7 rotates.
Be exactly more than a kind of structural feature and action effect of turbosupercharger nozzle ring capable of changing cross sections, its advantage: structure is simple, reduces the area of contact between shifting disc and auxiliary member, enhances the limit function of self.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
