Abstract
The utility model relates to a mounting distance variable differential assembly and belongs to the technical field of truck driving axles. The mounting distance variable differential assembly mainly solves the problem that, due to a constant bearing spacing, existing differential assemblies require two or three different differential housing assemblies to determine corresponding mounting distances to result in an overlarge quantity of the differential housing assemblies. The mounting distance variable differential assembly is mainly characterized by comprising a differential assembly, a bearing and a bearing cap, wherein the bearing and the bearing cap are mounted at both ends of the differential assembly; the external ends of the inner circles of the bearing and the bearing cap are provided with threads and adjusting nuts; the adjusting nuts are riveted with ring-shaped locking gaskets. By adjusting the differential housing assembly to match the mounting distance of driven gears at different speed ratios, the design number of the differential housing assembly can be reduced, and the weight of parts of the driven bevel gears can be reduced. The mounting distance variable differential assembly has the advantages of being simple in structure and applicable to differential speed ratios of the same axle assembly.
Description
Technical field
The utility model belongs to truck driving axle technical field.Be specifically related to a kind of differential assembly of ransaxle variable mounting distance.
Background technique
On truck driving axle, same axle assembly has different speed ratios, and to meet different drive conditions, different speed ratios can cause driven wheel of differential to have different mounting distances.Traditional solution is, in the situation that distance between bearings is constant, determines the different differential case assemblies of 2-3 kind, determines corresponding mounting distance.So not only can cause differential case assembly too much, and part driven wheel of differential can be blocked up overweight, cause design cost of production to increase.
Summary of the invention
The purpose of this utility model is exactly that a kind of simple in structure, change mounting distance differential assembly that can adapt to the different speed ratios that same axle assembly exists is provided for above-mentioned deficiency.
Technical solution of the present utility model is: a kind of change mounting distance differential assembly, comprises and it is characterized in that bearing and the bearing cap at differential assembly and differential assembly two ends: on described bearing and bearing cap inner ring outer end, be provided with screw thread and adjusting nut; On described adjusting nut, riveted joint has ring-type locking gasket.
The utility model is due on existing differential assembly and the bearing at differential assembly two ends and the basis of bearing cap, bearing and bearing cap outside is provided with to screw thread and adjusting nut, on adjusting nut, riveted joint has ring-type locking gasket, thereby can adopt the method for axial left and right adjustment differential case assembly that driven wheel of differential mounting distance is adjusted in (+-5mm) scope, to meet the requirement of driven wheel of differential mounting distance.The utility model can reduce differential case assembly design quantity, alleviates the weight of part driven wheel of differential, reduces cost of parts.The utlity model has feature simple in structure, to adapt to the different speed ratios of same axle assembly existence, be mainly used in the differential assembly of ransaxle variable mounting distance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1.Bearing 3 and the bearing cap 5 at differential assembly 4 and differential assembly 4 two ends are same as the prior art.Different is to be provided with screw thread 1 and adjusting nut 2 on bearing 3 and bearing cap 5 inner ring outer ends, and on this adjusting nut 2, riveted joint has ring-type locking gasket.By adjusting adjusting nut 2 displacement in the axial direction, can make bearing 3 move left and right (two ends regulate, and keep the constant situation of distance between bearings) simultaneously, thereby make the movement of differential assembly 4 integral body, meet the requirement of driven wheel of differential mounting distance.Adjusting nut 2 and bearing 3 one sides respectively leave adjusting play.After adjusting nut is adjusted to the right place, by the ring-type locking gasket flange being riveted on adjusting nut.
Claims (1)
1. one kind becomes mounting distance differential assembly, the bearing (3) and the bearing cap (5) that comprise differential assembly (4) and differential assembly (4) two ends, is characterized in that: on described bearing (3) and bearing cap (5) inner ring outer end, be provided with screw thread (1) and adjusting nut (2); The upper riveted joint of described adjusting nut (2) has ring-type locking gasket.
