Abstract
The invention discloses a welded-type rear cover of an automobile through axle housing, belonging to an automobile drive axle. The welded-type rear cover of an automobile through axle housing is characterized in that the welded-type rear cover is mainly installed and welded by a cover body and a connection base, wherein the cover body is in a cavity round-basin shape; a vertical frustum-shaped bulge is arranged on the right of the center of the front surface of the cover body; the left part and the right part of the front surface of the cover body are both circular-arc planes; the upper part of the left circular-arc plane of the cover body is provided with a base hole for welding the connection base; the lower part of the left circular-arc plane of the cover body is provided with an oil hole with an internal thread for screwing an oil-drainage plug screw; the connection base is a step-shaped cylinder, wherein the external diameter of the rear-end section of the step-shaped cylinder is small; the upper circumference of the front-end section of the connection base is evenly provided with three semicircle lugs; the lugs are evenly provided with connection screw holes; the connection base is provided with a center step hole, wherein the diameter of the rear-end section of the center step hole is small, and the diameter of the front-end section of the center step hole is big; the center step hole is used for the through shaft to correspondingly penetrate through and being screwed with bolts for fastening and positioning; and the rear cover and the through axle housing are welded. The welded-type rear cover has the advantages of good welding performance and light weight and has small possibility of leaking oil.
Description
Technical field
The invention belongs to automobile drive axle, especially relate to the bonnet that a kind of automobile connects axle housing.
Technical background
The bonnet that existing automobile connects axle housing adopts the heavier Casting Parts of weight more; Often because the back tegmental wall is thin; In casting process, occur foundry defect easily, cause the bonnet leakage of oil, and as cast bonnet weldability is relatively poor; Be difficult for being welded to and connect on the axle housing, in use also occur easily after the welding snapping, oil leakage phenomenon.
Summary of the invention
The objective of the invention is to propose the welded type bonnet that a kind of automobile connects axle housing, in light weight, intensity is good, and is good with the axle housing weldability, not easy oil leakage, long service life.
The objective of the invention is to realize like this, a kind of automobile connects the welded type bonnet of axle housing, it is characterized in that: the welded type bonnet that this automobile connects axle housing is mainly formed by lid and Connection Block assembly welding; This lid is cavity circle basin shape, and this lid can be steel stamping part, and taking at the middle part of the front surface of this lid is that vertical taper type is protruding; And the left part of lid front surface and right part are the circular arc plane, offer a hole on the top on the left circular arc plane of lid, are used to the Connection Block that is welded; Tapped oilhole is offered in bottom on circular arc plane, a lid left side, is used for the spinning drain screw, and Connection Block is welded in the seat hole on lid; This Connection Block is the little stepped cylinder of rear end section external diameter, and the rear end section that this external diameter is little is inserted in the seat hole and the circumference welding, and circumference uniform distribution has three semicircle lugs on the big front end rigion of the external diameter of Connection Block; On this lug, all offer the connection screw, and it is little and center stepped hole that the leading portion diameter is big is used for correspondence to install thru shaft and spinning bolted location on this Connection Block, to offer the rear end section diameter; This bonnet is integrally welded with the perforation axle housing; Good welding performance, and in light weight, not easy oil leakage.
Automobile proposed by the invention connects the welded type bonnet of axle housing, and is rational in infrastructure, uses reliably, in light weight, makes simply, and weldability is good, not easy oil leakage after the welding.
Combine accompanying drawing and embodiment that the welded type bonnet that automobile proposed by the invention connects axle housing is described further at present.
Description of drawings
Fig. 1 is that the master that automobile proposed by the invention connects the welded type bonnet of axle housing looks scheme drawing.
Fig. 2 is an A-A generalized section among Fig. 1.
Fig. 3 is a B-B generalized section among Fig. 1.
Among Fig. 1-Fig. 3:
1, lid 2, Connection Block 3, lug 4, oilhole 5, seat hole 6, center stepped hole
The specific embodiment
From Fig. 1-Fig. 3, can find out: a kind of automobile connects the welded type bonnet of axle housing, it is characterized in that: the welded type bonnet that this automobile connects axle housing is mainly formed by lid 1 and Connection Block 2 assembly weldings, and this lid 1 is cavity circle basin shape; This lid 1 can be steel stamping part, and taking at the middle part of the front surface of this lid 1 is that vertical taper type is protruding, and the left part of lid 1 front surface and right part are the circular arc plane; A hole 5 is offered on top on the left circular arc plane of lid 1, and the Connection Block 2 that is used to be welded is offered tapped oilhole 4 in the bottom on lid 1 left circular arc plane; Be used for the spinning drain screw, the Connection Block 2 that is welded in the seat hole 5 on lid 1, this Connection Block 2 is the little stepped cylinder of rear end section external diameter; The rear end section that this external diameter is little is inserted in the seat hole 5 and the circumference welding, and circumference uniform distribution has three semicircle lugs 3 on the big front end rigion of the external diameter of Connection Block 2, on this lug 3, all offers the connection screw; And on this Connection Block 2, offer little and the center stepped hole 6 that the leading portion diameter is big of rear end section diameter; Be used for correspondence and install thru shaft and spinning bolted location, this bonnet is integrally welded with the perforation axle housing, good welding performance; And in light weight, not easy oil leakage.
