Abstract
The utility model discloses a half shaft and sun wheel assembly. The half shaft and sun wheel assembly comprises a half shaft and a sun wheel arranged at one end of the half shaft, and the half shaft and the sun wheel are in an integrally-molded structure. The half shaft and sun wheel assembly has the advantages that the half shaft and the sun wheel are in the integrally-molded structure, the structure of the half shaft and sun wheel assembly is simple, installation procedures are simplified, and machining cost is reduced.
Description
Technical field
The utility model relates to drive axle field, specifically a kind of semiaxis band sun wheel assembly.
Background technology
Traditional semiaxis and sun wheel assembly follow conventional lines basically, and automotive axle designs, and adopts parts processing to form, and is then by spline engagement, very high to the requirement on machining accuracy of housing; Traditional semiaxis and sun wheel assembly spline will be processed respectively, waste of manpower and material resources, and because the difference of car load easily causes lack of lubrication also often to exist spline engagement to burn the generation of situation to death.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of semiaxis band sun wheel assembly, and semiaxis and sun wheel one are moulding, have saved engagement operation and the manufacturing procedure of Formation of Axle Shaft Spline and sun wheel spline, and is time saving and energy saving and reduced tooling cost.
The technical solution of the utility model is:
Semiaxis band sun wheel assembly comprises semiaxis and the sun wheel that is arranged on semiaxis one end, and described semiaxis and sun wheel are integrated shaping structure.
Described semiaxis is provided with male splines on the other end with sun wheel one end relatively.
Be provided with knock hole on the end face of described semiaxis with male splines.
Advantage of the present utility model:
(1), semiaxis of the present utility model and sun wheel one shaping structure, engagement operation and the manufacturing procedure of Formation of Axle Shaft Spline and sun wheel spline have been saved, simplify assembly technology, improve efficiency of assembling, because making the housing precision reduce, the selection of integral structure becomes possibility, for the reduction of cost lays the foundation, avoided requiring to affect because of the right alignment out of reach of two spline shelves the generation of axle assembly quality fault; And the impact resistance of sun wheel and the driving torque of lift bridge assembly have been improved; Due to semiaxis and the sun wheel formula structure that always becomes one, the transmission noise of whole bridge also further reduces;
(2), be provided with knock hole on the utility model semiaxis, adopt ejector pin to fix half shaft end, guaranteed the stability of semiaxis installation and positioning structure.
Semiaxis of the present utility model and sun wheel are integrated shaping structure, and it is simple in structure, simplify installation procedure, have reduced tooling cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
See Fig. 1, semiaxis band sun wheel assembly comprises semiaxis 1 and the sun wheel 2 that is arranged on semiaxis 1 one ends, and semiaxis 1 and sun wheel 2 are integrated shaping structure, semiaxis 1 is provided with male splines 3 on the other end with sun wheel 2 one ends relatively, is provided with knock hole 4 on the end face of semiaxis 1 with male splines 3.
Claims (3)
1. semiaxis band sun wheel assembly, comprise semiaxis and the sun wheel that is arranged on semiaxis one end, and it is characterized in that: described semiaxis and sun wheel are integrated shaping structure.
