The utility model discloses an integral cast bridge housing, comprising a bridge housing (1) and an axle head (2), and is characterized in that the bridge housing (1) and the axle head (2) are cast as one body, the casting material is QT600-3, and the heat treatment at the axle head (2) is first normalizing treatment and then quenching treatment; the utility model has a long service life, few bridge housing failures, low manufacturing cost, simple process, and low maintenance cost, and is suitable for medium and heavy engineering dump trucks and mining vehicles, and improves the bearing capacity and performance requirements of the bridge housing.
Description
Technical field:
The utility model relates to engineering dump truck and mining driving skills art field, is a kind of integral type casting bridge shell concretely, in being suitable for, heavy engineering dumping car and mining car.
Background technology:
Along with the development of Domestic Automotive Industry, in, heavy duty truck enters high-speed development period, corresponding driving axle assembly demand also increases thereupon.In, heavy engineering dumping car and mining automobile-used axle housing develop to high bearing capacity, high performance requirements direction, and the axle housing structure of using at present is generally towards the weldering axle housing, be to be welded by two and half shells, axle housing and spindle nose place also adopt Type of Welding, and this axle housing produces the axle housing failure mode because of welding, the manufacturing cost height, easy fracture in use, the life-span is short, complex process, the maintain and replace trouble, waste of manpower and material resources.
Summary of the invention:
The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and a kind of integral type casting bridge shell is provided, mainly solve existing axle housing and produced problems such as easy fracture in axle housing failure mode, manufacturing cost height, the use, life-span weak point, complex process, maintain and replace trouble, waste of manpower and material resources because of welding.
In order to achieve the above object, the utility model is achieved in that the integral type casting bridge shell, and it comprises axle housing and spindle nose, its special character is that axle housing and spindle nose are cast into one, and cast material is selected QT600-3 for use, and the principal particulars of material itself is middle high strength, inductile, resistance to abrasion is better.In order to improve the load-carrying properties requirement at spindle nose place, be first normalizing treatment Quenching Treatment then to the heat treatment at spindle nose place, make hardness reach HB229-269, tensile strength 740-930N/mm
2
Compared with the prior art integral type casting bridge shell described in the utility model has following good effect: realized that 1, spindle nose and axle housing are integrated, promoted the performance requriements of bearing position, spindle nose place and the service life of axle housing; 2, by by the transformation towards weldering formula axle housing to the integral type casting bridge shell, reduced the axle housing failure mode that produces because of welding, simultaneously, the axle housing of the weldering formula that liquidates has mutually also reduced manufacturing cost; 3, technology simply, easy fracture not, saved service expenditure.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and describe the utility model integral type casting bridge shell in detail.
Examples of implementation, referring to Fig. 1, cast material is selected QT600-3 for use, and the principal particulars of material itself is middle high strength, inductile, resistance to abrasion is better, axle housing 1 and spindle nose 2 are cast into one by foundry technique, in order to improve the load-carrying properties requirement at spindle nose place, are first normalizing treatment Quenching Treatment then to the heat treatment at spindle nose place, make hardness reach HB229-269, tensile strength 740-930N/mm
2
Integral type casting bridge shell of the present utility model in being suitable for, heavy engineering dumping car and mining car, has promoted the load-carrying capacity and the performance requriements of axle housing.
