Description
Technical field
The utility model is related to machinery manufacturing technology field more particularly to a kind of lightweight clutch cans being conducive to heat dissipation.
Background technology
" constant velocity cardan joint " is the important component in car drive system, and effect is by the power of engine from speed changer
It is transmitted to driving wheel, driving car is run at high speed.There are many constant velocity joint types for car, wherein it is ball to apply at most
Type constant velocity joint and triangle posture constant velocity cardan joint, it mainly have sliding sleeve, three-way axis, transmission shaft, inner race, retainer,
Clutch can major part forms.Since constant velocity cardan joint transmits heavy driving moment, with by load weight, high transmission accuracy needs
The amount of asking is very big, and is safety member, therefore its major part is all made of fine forge piece and is process.
Existing clutch can shape is as shown in Figure 1, big with volume, and weight is laid particular stress on, the high feature of material cost, same to clock
The thickness of shell of shape shell is big, the heat dissipation being unfavorable for inside drive shaft, leads to the rising of clutch can internal temperature, reduces in drive shaft
Portion's ball and alley wear-out life influence grease lubrication, reduce transmission efficiency.
Utility model content
It is bell to provide a kind of lightweight being conducive to heat dissipation in order to overcome above-mentioned problem of the prior art for the utility model
Shell.
To achieve the goals above, the utility model uses following technical scheme：
A kind of lightweight clutch being conducive to heat dissipation, including clutch can shell, if the clutch can enclosure interior is equipped with
The outer surface of the dry alley contoured surface being spaced apart, the clutch can shell is equipped with several grooves, and the groove is located at two
Between adjacent alley contoured surface.
The distribution of clutch can thickness of shell is simultaneously uneven, and the thickness between clutch can outer surface and alley face is most thin, and
Thickness of shell between two alleys of clutch can is the maximum position of thickness with respect to other positions, in order to reduce the weight of clutch can
Amount, the utility model between clutch can outer surface and two adjacent alley contoured surfaces be bell thickness of the shell maximum position at into
Row fluting design groove.
Preferably, the groove is distributed around clutch can axisymmetrical, steadily of centre of gravity, it is ensured that run well.
Preferably, the number of the groove is adapted or halves with ball steel ball number, i.e. six alley clutch cans fluting
Number is 6 or 3, and 8 alley clutch cans fluting number is 8 or 4.
Preferably, the slot area of the groove is avoided at clutch can and dust cover link position.Do not influence dust cover
Installation with clutch can and drive shaft sealing performance influence dust cover and clutch can assembly area if slot area is excessive, need
Dust cover is needed to redesign.
Preferably, the groove is spherical structure.
Preferably, the groove is ellipsoid structure.
Preferably, the groove inner surface equipped with concave-convex alternate nutty structure, further increases and cross-ventilation
Contact area, be easy to radiate.
Therefore, the utility model has the advantages that：
（1）Clutch can shell loss of weight, reduces cost；
（2）Clutch can thickness of shell is thinned, and is conducive to the heat transfer of clutch can, increases the drive shaft service life；
（3）Fluting form is reasonable, can increase clutch can surface area, increases the thermal convection current with air, is also beneficial to bell
The heat dissipation of shell increases the drive shaft service life.
Description of the drawings
Fig. 1 is the sectional view of the prior art.
Fig. 2 is a kind of structural schematic diagram of the utility model.
Fig. 3 is the sectional view of Fig. 2.
Fig. 4 is the sectional view of the slotting position of Fig. 2.
In figure：Clutch can shell 1, alley contoured surface 2, groove 3.
Specific implementation mode
Below by specific embodiment, and in conjunction with attached drawing, the technical solution of the utility model is made more specifically
It is bright.
As in Figure 2-4, a kind of lightweight clutch being conducive to heat dissipation, including clutch can shell 1, in clutch can shell
Portion is equipped with several alley contoured surfaces 2 being spaced apart, and the outer surface of clutch can shell is equipped with the groove 3 of 6 ellipsoid structures,
That is the number of six alley clutch can institutes recessing is 6, and groove is located between two adjacent alley contoured surfaces and the fluting of groove
Region is avoided at clutch can and dust cover link position, and groove is distributed around clutch can axisymmetrical.
The distribution of clutch can thickness of shell is simultaneously uneven, and the thickness between clutch can outer surface and alley face is most thin, and
Thickness of shell between two alleys of clutch can is the maximum position of thickness with respect to other positions, in order to reduce the weight of clutch can
Amount, as shown in figure 4, between clutch can outer surface and two adjacent alley contoured surfaces be bell thickness of the shell maximum position at into
Row fluting design groove, while the installation in order to not influence dust cover and clutch can and drive shaft sealing performance, slot area because
It avoids exceeding as possible at clutch can and dust cover link position, if slot area is excessive, influences dust cover and assembled with clutch can
Region needs to need to redesign to dust cover.
Auto parts and components loss of weight is the light-weighted trend of vehicle, major main engine plants for drive shaft performance requirement increasingly
Height increases fluting between clutch can outer profile and alley face, considerably reduces the weight of clutch can, can reduce and be produced into
This；The thickness of clutch can also reduces accordingly simultaneously, is conducive to the heat dissipation inside drive shaft, and in addition fluting is rationally, bell
Shell surface area can also increase accordingly, increase the thermal convection current of clutch can and air, the heat dissipation of clutch can is also beneficial to, to improve
The service life of drive shaft.
The above is only the preferred embodiment of the present invention, not makees limit in any form to the utility model
System, on the premise of not exceeding the technical scheme recorded in the claims also other variations and modifications.
