Abstract
The utility model discloses a kind of anti-fracture cross axles, including cross shaft body, the outside of the cross shaft body is equidistantly equipped with " 4 " a flat surface, each flat surface is vertically equipped with connecting shaft, the side of the connecting shaft is equipped with strip groove, the inner wall of the cross shaft body is rounded, and it is equipped with latch, the side of the cross shaft body is equipped with convex body, the oil groove of strip groove root in this kind of room fracture cross axle removal connecting shaft, the intensity of connecting shaft is improved to a certain extent, to reduce the fracture of connecting shaft.
Description
Technical field
The utility model relates to a kind of cross axle, specially a kind of anti-fracture cross axle.
Background technique
Also known as crossed joint, i.e. universal joint, English name universal joint are to realize that varied angle power transmits
Parts, for needing to change the position of transmission axis direction, it is " joint " portion of the universal driving device of automobile driving system
Part.Cross shaft rigid universal joint is widely used nonconstant velocity universal joint on automobile, and the maximum angle of cut of adjacent two axis of permission is
The ゜ of 15 ゜~20.Cross axle is one of cross shaft rigid universal joint key component.
But existing cross axle, connecting shaft root are equipped with oil groove, lead to the strength reduction of connecting shaft root, to make cross
Often there is fracture damage phenomenon in axis.
So how to design a kind of anti-fracture cross axle, becoming us will currently be solved the problems, such as.
Utility model content
The purpose of this utility model is to provide a kind of anti-fracture cross axles, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the utility model provides the following technical solutions: a kind of anti-fracture cross axle, including cross axle
Main body, the outside of the cross shaft body are equidistantly equipped with " 4 " a flat surface, and each flat surface is vertically equipped with connecting shaft,
The side of the connecting shaft is equipped with strip groove, and the inner wall of the cross shaft body is rounded, and is equipped with latch, the cross axle master
The side of body is equipped with convex body.
Further, strip groove root both ends are equipped with cambered surface, and the cambered surface radius is R2.5.
Preferably, the angle between the convex body and the flat surface is 30 °.
Compared with prior art, the utility model has the beneficial effects that this kind of anti-fracture cross axle is by removing connecting shaft
The oil groove of upper strip groove root, improves the intensity of connecting shaft, to reduce the fracture of connecting shaft.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the partial structural diagram of the utility model；
In figure: 1- cross shaft body；2- connecting shaft；3- flat surface；4- strip groove；5- cambered surface；6- convex body；7- latch.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of anti-fracture cross axle, including cross axle master
Body 1, the outside of the cross shaft body 1 are equidistantly equipped with " 4 " a flat surface 3, and vertical be equipped with connects in each flat surface 3
The side of axis 2, the connecting shaft 2 is equipped with strip groove 4, and the inner wall of the cross shaft body 1 is rounded, and is equipped with latch 7, described
The side of cross shaft body 1 is equipped with convex body 6, this kind of anti-fracture cross axle removes the oil groove of original 2 root of connecting shaft, comes
The intensity for enhancing connecting shaft 2, to reduce the phenomenon of rupture of connecting shaft 2.
Further, the 4 root both ends of strip groove are equipped with cambered surface 5, and 5 radius of the cambered surface is R2.5, will be original
Oil groove remove, make the root of the strip groove 4 in R2.5 cambered surface, and connect with the flat surface 3 of the cross shaft body 1, with
Enhance the intensity of the connecting shaft 2.
Preferably, the angle between the convex body 6 and the flat surface 3 is 30 °, is easy to use.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
