Abstract
The utility model relates to a novel axle housing rear cover structure, the axle housing rear cover is of a hemispherical structure, and the edge of the axle housing rear cover is flanged outwards to form a plane structure for welding with an axle housing body; the spherical surface is punched with a flat boss, a spherical pit is punched on the boss, a through hole is formed in the spherical pit, and the inner diameter of the through hole is provided with a thread for connecting a screw plug. For traditional welding plug seat structure, reduced the material cost and the welding cost of plug seat, avoided the oil leak inefficacy between axle housing rear cover and the plug seat to take place, promoted sealing reliability.
Description
Technical Field
The utility model belongs to car drive axle field, concretely relates to novel axle housing rear cover structure.
Background
In the domestic automobile driving axle, a stamping axle housing rear cover structure is mostly adopted, and a screw plug seat is welded on the axle housing rear cover and is used for connecting an oil filling screw plug. Due to the fact that the screw plug seat structure is added, the material cost and the welding cost of the screw plug seat are increased; and the screw plug seat and the axle housing rear cover are beneficial to sealing of a welding process, and oil leakage caused by welding defects often occurs.
Disclosure of Invention
The utility model aims to solve the problems that in the existing automobile driving axle, the material cost of the screw plug seat is increased because the rear cover of the stamping axle housing is welded with the screw plug seat structure for connecting the oil filling screw plug; leading to increased welding costs for the plug seat; the kneck oil leak scheduling problem that leads to spiral shell stopper seat and axle housing rear cover, the utility model provides a novel axle housing rear cover structure, reduce cost promotes the sealing reliability.
The purpose of the utility model is realized through the following technical scheme:
a novel axle housing rear cover structure is characterized in that an axle housing rear cover 1 is of a hemispherical structure, and the edge of the axle housing rear cover 1 is flanged outwards to form a plane structure and is used for being welded with an axle housing body 3; the spherical surface is punched with a plane boss 4, a spherical pit 5 is punched on the boss 4, a through hole is formed in the spherical pit 5, and the inner diameter of the through hole is provided with a thread for connecting the screw plug 2.
The beneficial effects are as follows:
the utility model discloses a cover punching press sphere pit behind the axle housing to processing hole position hole has increased the axial length of screw hole on the pit. For traditional welding plug seat structure, reduced the material cost and the welding cost of plug seat, avoided the oil leak inefficacy between axle housing rear cover and the plug seat to take place, promoted sealing reliability.

Detailed Description
The invention is further elucidated with reference to the drawing.
As shown in fig. 1-6, the utility model provides a novel axle housing rear cover structure, wherein the axle housing rear cover 1 is of a hemispherical structure, and the edge of the axle housing rear cover 1 is flanged outwards to form a plane structure for welding with an axle housing body 3; the spherical surface is punched with a plane boss 4, a spherical pit 5 is punched on the boss 4, a through hole is formed in the spherical pit 5, and the inner diameter of the through hole is provided with a thread for connecting the screw plug 2. The screw thread diameter of the screw plug 2 is screwed into the screw hole of the axle housing rear cover 1 and is screwed, and the screw hole of the axle housing rear cover 1 is used for filling gear oil into the axle housing inner cavity. Two end faces of the planet gear shafts 2 are matched with one end face of the two short planet gear shafts 1 to limit axial movement.
The novel axle housing rear cover blank of the utility model adopts a steel plate to be punched into a semispherical structure, and the edge of the semispherical is flanged outwards into a plane structure for welding with the axle housing body; a flat boss is punched on the spherical surface, and a spherical pit is punched on the boss for processing a threaded hole. Processing a threaded hole in a spherical pit of the axle housing rear cover blank for connecting a screw plug 2; due to the adoption of the spherical pit structure, the axial length of the threaded hole is increased, and the sealing reliability is ensured.
In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Although embodiments of the present invention have been shown and described, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that changes, modifications, substitutions and alterations can be made to the above embodiments by those of ordinary skill in the art within the scope of the present invention.
