Abstract
The utility model relates to a differential case for a drive axle, which is applicable to a main retarder of a drive axle for a truck or coach chassis. By providing the differential case with the structure different from the traditional structure, the problem in the conventional differential of unsmooth lubrication, caused by that lubrication oil difficulty flows inside the differential case along a hole of the differential shell, can be solved. The differential case comprises a differential case body and holes at the two ends of the differential case; holes are tapered holes; and the hole diameter of the hole which is close to the outer end of the differential case is small. With the adoption of the differential case for the drive axle provided by the utility model, the lubrication condition of a planetary gear of the differential can be effectively improved, and the service life of the part can be prolonged.
Description
Technical field:
The utility model relates to a kind of differential carrier, particularly a kind of drive axle differential case that is applicable to card, passenger-carrying chassis main reducing gear of drive axle.
Background technique:
Ransaxle is as one of automobile three large core drive transmission part assemblies, by parts such as input flange, gear pair, differential mechanism, semiaxis, wheel hubs with transmission of power to wheel.Wherein differential mechanism is comprised of parts such as differential carrier, cross axle, planetary pinions again, when automobile is traveling in uneven road surface or turns, because the left and right wheels rotating speed is different, come balance tire speed discrepancy by differential mechanism, prevent the excessive wear that is rigidly connected tire is caused.Wherein differential carrier is divided into again two and half shells, is integrated by Bolt Connection, realizes transmitting torque and supports the function that its internal rows star-wheel meshes.The tradition differential carrier, two stomidium is isodiametric cylindrical hole, during differential mechanism rotating, it is inner that lubricant oil is difficult for flowing into differential carrier along hole, thereby cause lubricated not smooth.
Summary of the invention:
The utility model is difficult for flowing into the inner not smooth problem of lubricating that causes of differential carrier along the differential carrier hole thereby solved present differential mechanism lubricant oil by a kind of differential carrier different from conventional construction is provided.
The utility model is realized by following technological scheme:
A kind of drive axle differential case comprises the hole at differential carrier body and differential carrier two ends, and the hole is cone shape hole, and little near the aperture of differential carrier outer end.
The utility model can effectively improve the lubricating condition of differential pinion gear, extends part working life.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the local enlarged diagram in I place of Fig. 1.
Embodiment:
As depicted in figs. 1 and 2, by changing the structural design of differential carrier body 1, by the cylindrical taper shape that changes into, during differential mechanism rotating, lubricant oil just can be under centrifugal action flows into differential carrier inside along cone shape hole with hole 2 inner wall shape at differential carrier two ends.Improve the lubricating condition of differential pinion gear, extended part working life.
Claims (1)
1. drive axle differential case comprises the hole at differential carrier body and differential carrier two ends, and it is characterized in that: the hole is cone shape hole, and little near the aperture of differential carrier outer end.
