Abstract
The utility model relates to an inter-axle differential of a vehicle drive bridge, in particular to an improved inter-axle differential of a vehicle drive bridge. The utility model aims at proposing an improved inter-axle differential of a vehicle drive bridge for overcoming the defects brought by the defect on the aspect of the shell structure of the existing inter-axle differential. The utility model is characterized in that the shell of the differential is arranged to be an annular body; the inner ring surface of the annular body is one part of a spherical surface; the inner ring surface is corresponding to the spherical surface assembled on the outer surface of the satellite gear of a cross shaft. As the shell of the inter-axle differential implemented by the scheme is arranged into an integral spherical ring and is not separately arranged into a left half shell and a right half shell as well as is provided with a cross shaft hole, the inter-axle differential of a vehicle drive bridge not only simplifies the structure of the shell, but also is beneficial to the processing and manufacturing technique of the shell as well as the assembling of the drive bridge. The inter-axle differential of a vehicle drive bridge has a simple and reasonable design and relates to a beneficial improvement.
Description
Technical field
The utility model relates to the automobile drive axle interaxle differential, especially about a kind of improved automobile drive axle interaxle differential.
Background technology
At present, the differential casing of automobile drive axle interaxle differential is made and assembling by left and right two halves split, and also be shaped on four axis holes that match with center cross on the differential casing, therefore, the drive axle interaxle differential not only in complexity aspect the manufacturability of processing and manufacturing, take a lot of work, time-consuming, and when assembling, have aforesaid defective or deficiency equally.So the production of the drive axle interaxle differential of existing structure, assembly cost are also than higher.
The utility model content
The purpose of this utility model is to have the deficiency that the automobile drive axle interaxle differential brings because of the defective of differential gear box configuration aspects now for overcoming, and propose a kind of improved drive axle interaxle differential.
For realizing that this purpose adopts following technical scheme: a kind of improved automobile drive axle interaxle differential, comprise differential gear box, center cross, thru shaft, planetary wheel, it is characterized in that differential gear box is set to--individual ring body, the medial surface of ring body is the part of sphere, and the shape of medial surface is corresponding with the sphere that planetary outside face is constituted; Center cross is that spline is connected with thru shaft.
Press the improved drive axle interaxle differential that this programme is implemented, because differential casing is set to a single-piece Internal Spherical Surface ring, no longer be divided into left and right sides two halves housing and cross shaft hole is set, not only simplify the structure of housing, also helped the assembling of the process for machining and manufacturing and the drive axle thereof of housing simultaneously.The utility model simple structural design is reasonable, has reduced productive costs, is a kind of useful improvement.
Description of drawings
Fig. 1 is an axial section structural representation of the present utility model.
Fig. 2 is the structural representation of differential gear box.
The specific embodiment
Be described in further detail below in conjunction with accompanying drawing.
A kind of automobile drive axle interaxle differential is made up of active cylindrical wheel 1, differential gear box 2, center cross 3, planetary wheel 4, thru shaft 5, axle side gear 6 and mouth 7, for overcoming defective and the deficiency that existing automobile drive axle interaxle differential fault of construction is brought at aspects such as processing and manufacturing and assemblings, the utility model is improved to a ring body 2 with differential gear box, this ring body 2 is a single-piece, two and half shells about no longer branch is made as are not provided with the axis hole that is equipped with center cross simultaneously yet on this ring body 2.The medial surface 20 of ring body 2 is the part of a sphere, and the shape of the medial surface 20 of ring body 2 is corresponding with the spherical shape that outside face constituted of planetary wheel 4.For realizing the output of differential-speed dynamic, be set to spline bonded assembly structure between center cross 3 and the thru shaft 5, differential-speed dynamic is exported with the engagement of axle side gear 6 and by making key bonded assembly output shaft 7 with axle side gear 6 via planetary wheel 4.
Claims (3)
1, a kind of improved automobile drive axle interaxle differential comprises differential gear box, center cross, thru shaft, planetary wheel, it is characterized in that differential gear box is set to a ring body.
2, by the described improved automobile drive axle interaxle differential of claim 1, the medial surface that it is characterized in that ring body is the part of sphere, and the shape of medial surface is corresponding with the sphere that planetary outside face is constituted.
