Abstract
The utility model discloses an automotive differential assembly. The automotive differential assembly comprises an input shaft and a main-driving wheel. The radial-direction coordination between the inlet shaft and the main-driving wheel uses a needle roller bearing; the axial-direction coordination uses a thrust bearing. The automotive differential assembly has the advantages that the automotive differential assembly replaces the existing shaft sleeve with the needle roller bearing, the service life of the main-driving wheel prolongs more than five times, the friction coefficient is low; the automotive differential assembly replaces the existing cooper pad with the thrust bearing; the abrasion of the main-driving wheel is reduced on the condition of lacking lubrication.
Description
Technical field
The utility model is specifically related to a kind of automobile differential assembly.
Background technique
At present in the differential assembly of automobile, input shaft is to cooperate by axle sleeve with radial fit between the driving wheel, and when lacking under the lubricated oil condition, the wearing and tearing of driving wheel are more serious; Input shaft is to cooperate by copper packing with axial cooperation between the driving wheel, and when driving wheel moved right, because driving wheel has formed friction with copper packing, driving wheel wore and tore.
The content of model utility
The shortcoming that exists for solving prior art the utility model proposes a kind of novel automobile differential assembly.
The technical solution adopted in the utility model is as follows:
A kind of automobile differential assembly comprises input shaft and a driving wheel, and the radial fit between described input shaft and the driving wheel adopts needle bearing, axially cooperates to adopt thrust-bearing.
The beneficial effects of the utility model are: replaced original axle sleeve with needle bearing, the life of driving wheel more than 5 times, friction factor is little, has replaced original copper packing with thrust-bearing, is lacking in the lubricated situation, has reduced the wearing and tearing of driving wheel.
Description of drawings
Fig. 1 structural drawing of the present utility model;
Among the figure, 1 driving wheel, 2 needle bearings, 3. thrust-bearing, 4. input shaft
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
Structure of the present utility model as shown in Figure 1, a kind of automobile differential assembly comprises input shaft 4 and a driving wheel 1, radial fit between described input shaft 4 and the driving wheel 1 adopts needle bearing 2, axially cooperates to adopt thrust-bearing 3.
Claims (1)
1. an automobile differential assembly comprises input shaft and a driving wheel, it is characterized in that: the radial fit between described input shaft and the driving wheel adopts needle bearing, axially cooperates to adopt thrust-bearing.
