Specific embodiment
Below in conjunction with the accompanying drawings 2, a kind of constant velocity driving shaft universal joint housing of the utility model is described in further detail.
A kind of constant velocity driving shaft universal joint housing of the utility model, please refers to Fig.2, and expands including housing shank 1 and housing
Oral area 2, the housing shank 1 are integrally formed or are fixedly connected with the housing expansion mouth 2, and the housing expansion mouth 2 is equipped with close
Big envelope 4, for inner cavity 3 between the expansion mouth 2 and the sealing shroud 4, the bottom surface of the inner cavity 3 is plane, the housing shank 1
It is set with the junction of the housing expansion mouth 2 there are one recessed counterbore 5.In this way, from the bottom surface of the housing cavity 3 to described
Housing shank 1 opens up a counterbore, since the housing shank 1 eliminates excess stock so that the constant velocity driving shaft is universal
The weight saving of housing is saved, the weight of entire automobile can also mitigate.In the case that other conditions are identical, car weight is bigger, needs to send out
The power that motivation is provided also can be bigger, that is, oil consumption can be bigger.The constant velocity driving shaft universal joint housing, by described heavy
Hole 5 eliminates extra material, reaches loss of weight purpose, while reduce oil consumption, meets automotive light weight technology requirement.Relative to existing
For technology, a kind of constant velocity driving shaft universal joint housing of the utility model has the following advantages：Meeting casing rigidity requirement
Under the premise of, excess stock is eliminated, reaches loss of weight purpose, meets automotive light weight technology requirement, while reduce oil consumption, to improving
The continuation of the journey of fuel economy or electric vehicle has a positive effect.
A kind of constant velocity driving shaft universal joint housing of the utility model, in front on the basis of technical solution, please refers to figure
2, it can also be：The counterbore 5 is cylinder formula counterbore.In this way, being because cylinder formula counterbore is easy to process, forming is easy, and
It can ensure the uniform loss of weight of housing shank, to meet the intensity requirement of housing.In front on the basis of technical solution, into one
Step is preferably, and the lateral cross section of the counterbore 5 is round or regular polygon.In this way, it is because being other shapes with lateral cross section
The counterbore of shape is compared, and lateral cross section is easier for round and regular polygon counterbore molding, most widely used.In addition, transverse cutting
Face be circular counterbore compared with lateral cross section is the counterbore of regular polygon, make the shank loss of weight more uniform, processing it is more square
Just.
A kind of constant velocity driving shaft universal joint housing of the utility model, in front on the basis of technical solution, please refers to figure
2, it can also be：It is set at the counterbore 5 there are one blanking cover 6, the inner wall detachable-type sealed of the blanking cover 6 and the counterbore 5 is consolidated
It is fixed.In this way, can prevent lubricating grease from entering the counterbore 5, in the case where not increasing grease usage amount, universal joint is not influenced
Lubrication.In front on the basis of technical solution, it is further preferred that, the counterbore 5 includes a blind hole and a through-hole, institute
It states blind hole and is located at the housing shank 1, the through-hole is located at the housing expansion mouth 2, and the blanking cover 6 is set on the through hole,
The inner wall detachable-type sealed of the blanking cover 6 and the through-hole is fixed.In this way, due to the aperture of the through-hole and the blind hole not
Equally, a step can be formed between the through-hole and the blind hole, the blanking cover 6 can be blocked, prevents the blanking cover 6 from slipping into
In the blind hole.In front on the basis of technical solution, it is further preferred that, the blanking cover 6 has annular flange, the annular
The inner wall detachable-type sealed of flange and the counterbore 5 is fixed.In this way, the inner wall of the blanking cover 6 and the counterbore 5 is made more to stick on
It closes, makes better tightness.In front on the basis of technical solution, it is further preferred that, 6 middle part of blanking cover is put down equipped with boss
Face.In this way, it is possible to reduce machined surface, the blanking cover 6 can be integrally formed, and reduce processing cost, and the boss plane increases
The compactness connected between the annular flange and the plane of the blanking cover.
It is above-mentioned that only the specific embodiment of the utility model is illustrated, but can not be as the protection of the utility model
Range, the equivalent change or modification made by every design spirit according in the utility model, is deemed to fall this practicality
Novel protection domain.
