Abstract
The utility model discloses an oil retaining structure for a cast iron drive axle housing, which comprises a cast iron drive axle housing equipped with a ventilation plug and an annular oil retaining wall arranged on the lower surface of the ventilation plug and fixedly connected with the inner side of the cast iron drive axle housing. The oil retaining structure with low cost and simple process can be matched with various structures of ventilation plugs, so that the good ventilation effect is achieved, and the problems of ventilation plug oil-leaking and plugging and the ventilation plug corrosion and the like are effectively solved, and the service life of the ventilation plug and an axle assembly is prolonged.
Description
Technical field
The utility model relates to automotive field, specifically a kind of drive axle cast iron axle housing oil baffle structure.
Background technology
At present, the pattern of drive axle axle housing mainly contains three kinds: towards weldering, cast steel, cast iron, be mostly oil blocking cover of repair welding for the ventilation device of preceding two kinds of axle housings, under the prerequisite of not scurrying oil, finish its ventilatory function to guarantee breather stem vent plug.And for the third cast iron axle housing, owing to can not weld oil blocking cover, bolt up is complex process and may cause leakage of oil not only, so without any protection, often cause that the breather stem vent plug place scurries the wet goods fault.Drive axle is higher than ambient pressure because of the gear oil temperature build-up makes the axle housing air pressure inside in the running, for making the inner and outer air pressure unanimity, will add a ventilation device, makes the discharge that gas can be smooth, the ventilation device of Here it is axle housing.Owing to the high-speed operation of gear, strengthened the shallow speed that flies of lubricating oil, under unshielded situation, directly be thrown on the breather stem vent plug, thereby cause breather stem vent plug to scurry faults such as oil, obstruction and breather stem vent plug corrosion.High-temperature gas can not be discharged timely, and the temperature in the axle housing is raise rapidly, and key components and parts at high temperature is damaged and waits major failure, consequently influences axle assembly service life.
The utility model content
Deficiency at the prior art existence, technical problem to be solved in the utility model is, a kind of drive axle cast iron axle housing oil baffle structure is provided, this structure can solve the breather stem vent plug place and scurry the wet goods fault, can make the discharge that gas can be smooth, can solve again because of breather stem vent plug and scurry oil, obstruction, and cause and parts such as breather stem vent plug problem such as at high temperature be corroded.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of drive axle cast iron axle housing oil baffle structure, it comprises the drive axle cast iron axle housing that breather stem vent plug is installed, below its breather stem vent plug, the oily wall of the inboard captive joint one annular retaining of drive axle cast iron axle housing.
Above-mentioned drive axle cast iron axle housing oil baffle structure describedly should annular keeps off oily wall and is connected with drive axle cast iron axle housing integral type by the as cast mode.
Above-mentioned drive axle cast iron axle housing oil baffle structure, described annular is kept off oily wall and is provided with a port.
The advantage of a kind of drive axle cast iron of the utility model axle housing oil baffle structure is: at the oily wall of plain cast iron axle air vent plug Position Design casting annular retaining, prevented that effectively gear is thrown to breather stem vent plug air extractor duct place with lubricating oil, guarantee the timely discharge of high-temperature gas simultaneously, satisfied lubricating requirement; On, the simple basis of technology low, can cooperate, realize good ventilatory effect, effectively solve breather stem vent plug and scurry faults such as oil, obstruction and breather stem vent plug corrosion, the service life of having improved breather stem vent plug and axle assembly with multiple structural shape breather stem vent plug at cost.
Description of drawings
Fig. 1 is the utility model embodiment drive axle cast iron axle housing oil baffle structure scheme drawing.
The specific embodiment
Below in conjunction with drawings and the specific embodiments the utility model is described in further details.
As shown in the figure, the utility model drive axle cast iron axle housing oil baffle structure, it comprises the drive axle cast iron axle housing 1 that breather stem vent plug 2 is installed, below its breather stem vent plug 2, the oily wall 3 of the inboard captive joint one annular retaining of drive axle cast iron axle housing 1; This annular is kept off oily wall 3 and is cast as toroidal, the position is set is the axis of the oily wall 3 of annular retaining and the axis normal of breather stem vent plug 2, the center of its annulus is just in time at the admission port place, following bottom of breather stem vent plug 2, the direction relative with admission port kept off one side of oily wall 3 over against annular, thereby stop that high temperature oil droplet 6 directly gets rid of into breather stem vent plug 2, has avoided breather stem vent plug 2 to be immersed in for a long time and has caused corrosion in the oil; This annular is kept off oily wall 3 and is connected with drive axle cast iron axle housing 1 integral type by the as cast mode, has guaranteed oily wall 3 of annular retaining and drive axle cast iron axle housing 1 connection stability.Keep off in annular and to leave a port 4 on the oily wall, this port 4 can prevent effectively that gear is thrown to breather stem vent plug 2 air extractor duct places with lubricating oil, has guaranteed the timely discharge of high temperature gas flow 5 simultaneously, has satisfied lubricating requirement again.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
Claims (3)
