Abstract
A half axle gear gasket structure is characterized in that a half axle gear gasket is in a boss shape and consists of an axle tube and a shoulder of the axle tube, the outer diameter of the axle tube is matched with a differential case, the shoulder is attached to the plane of the differential case, and round holes of the axle tube and the shoulder of the axle tube are matched with a half axle gear; the circular hole of the differential case and the shaft hole of the shaft tube are in interference fit, the half axle gear gasket is fixed on the differential case, the shaft diameter of the half axle gear is arranged in the circular hole of the half axle gear gasket, and the shoulder of the half axle gear is attached to the flange plane of the half axle gear gasket. The utility model has the advantages that the half axle gear gasket is fixed on the differential case by adopting the axle tube structure with the flange surface, so the relative rotation between the half axle gear gasket and the differential case is avoided, and the abrasion of the half axle gear gasket on the end surface of the differential case is avoided; simultaneously, the axle diameter of the half axle gear is separated from the round hole of the differential case by a half axle gear gasket, and the abrasion of the axle diameter of the half axle gear to the round hole of the differential case is avoided, so that the reliability of the differential assembly is improved.
Description
Technical Field
The utility model belongs to the technical field of the differential mechanism of car axle, concretely relates to half axle gear gasket structure.
Background
The domestic automobile axle comprises a differential mechanism, a half axle gear gasket is arranged between a half axle gear and a differential mechanism shell, and due to the poor abrasion resistance of the differential mechanism shell, when the half axle gear rotates, the direct contact abrasion of the half axle gear to the differential mechanism shell is avoided. Because the half axle gear gasket adopts the annular structure, when the half axle gear is rotatory, still can drive the half axle gear gasket rotatory to lead to the wearing and tearing of half axle gear gasket to the differential mechanism shell, and then reduce differential mechanism assembly's performance and life-span.
Disclosure of Invention
The utility model discloses a solve the differential mechanism assembly in current car axle because the differential mechanism gasket adopts the loop configuration, when half gear is rotatory, drive the half gear gasket and rotate simultaneously to lead to the wearing and tearing of half gear gasket to the differential mechanism shell, lead to differential mechanism assembly's differential performance decline and life-span reduction scheduling problem, provide a half gear gasket structure, promote differential mechanism assembly's reliability.
The utility model discloses an adopt following technical scheme to realize:
a side gear spacer structure characterized in that: the half axle gear gasket is in a boss shape consisting of an axle tube and a shoulder of the axle tube, wherein the outer diameter of the axle tube is matched with the differential case, the shoulder of the axle tube is attached to the plane of the differential case, and round holes of the axle tube and the shoulder of the axle tube are matched with the half axle gear; the round hole of the differential case is in interference fit with the axle hole of the axle tube, so that the half axle gear gasket is fixed on the differential case without relative movement; the axle diameter of the half axle gear is arranged in the round hole of the half axle gear gasket, and the shoulder of the half axle gear is attached to the flange plane of the half axle gear gasket.
One end of the axle tube is in a flange surface structure, wherein the outer diameter of the axle tube is matched with the differential case, and the shoulder of the axle tube is matched with the differential case; the round hole of the axle tube is matched with the half axle gear; the end face of the flange is matched with the half axle gear; the flange end face is provided with the grooves with the rectangular cross sections distributed in the cross shape as oil passages, and the structure can improve the lubricating performance.
The utility model discloses use on differential mechanism assembly, realize the antifriction operation of half shaft gear to the differential mechanism shell, when differential mechanism assembly differential, produce relative rotation between half shaft gear and the differential mechanism shell, because the half shaft gear gasket is fixed on the differential mechanism shell, only produce sliding wear between half shaft gear and the half shaft gear gasket, avoided the wearing and tearing of differential mechanism shell.
Compared with the prior art, the beneficial effects of the utility model are that:
a half axle gear gasket structure, the half axle gear gasket replaces the circular structure of the principle by adopting the axle tube structure with the flange surface, and in the structure, because the half axle gear gasket is pressed and fixed on a differential case, the relative rotation between the half axle gear gasket and the differential case is effectively avoided, and the abrasion of the half axle gear gasket on the end surface of the differential case is avoided; simultaneously, the axle diameter of the half axle gear is separated from the round hole of the differential case by a half axle gear gasket, and the abrasion of the axle diameter of the half axle gear to the round hole of the differential case is avoided, so that the reliability of the differential assembly is improved.
