Abstract
A cast type axle housing body of a drive axle comprises an axle housing main body. The cast type axle housing body of the drive axle is characterized in that the axle housing main body is a whole body, a rear cover is arranged on the rear portion of the axle housing main body, a main speed reducer installation opening is formed in the front portion of the axle housing main body, a flange connected with a main speed reducer shell is arranged on the installation opening, the two sides of the axle housing main body are respectively provided with a semi-axle sleeve tube inserting portion provided with an inner hole, a reinforcing rib is arranged on the joint portion of the axle housing main body and each semi-axle sleeve tube inserting portion, the axle housing main body, the semi-axle sleeve tube inserting portions at the two ends and the rear cover are cast into a whole. The cast type axle housing body of the drive axle has the advantages that the number of parts is reduced and the weight of the axle housing main body is light; the structure is simple, the machining and assembling technological process is simplified, the machining accuracy can be guaranteed easily, manufacture is convenient, and cost is reduced; a main speed reducer assembly can be disassembled, assembled and adjusted under the premise that the whole axle is not disassembled, so that repair and maintenance are convenient.
Description
Technical field
The utility model belongs to a kind of automobile drive axle parts, particularly a kind of cast type Drive axle housing body.
Background technology
The Drive axle housing body is one of vital parts on the automobile drive axle housing assembly.The rigid drive axle axle housing plays a part to connect axle tube assembly and main gearbox assembly and supporting automobile load, and load is passed to wheel.The Drive axle housing body is load member, is again force transmission element, and it is again the main gearbox assembly shell of (containing differential assembly) simultaneously.
In vehicle traveling process, the Drive axle housing body bears heavy load.In order to reduce the unsprung weight of automobile, be beneficial to reduce live load, improve ride of vehicle, should make every effort to reduce the quality of Drive axle housing body under the prerequisite of proof strength and rigidity.The Drive axle housing body should be simple in structure, and is easily manufactured, is beneficial to reduce costs, and structure also should guarantee dismounting, adjustment, maintenance and the easy maintenance of main gearbox assembly.Also should consider when determining the Drive axle housing body construction automobile type, operating needs, create conditions, material supply etc.
The structure of automobile drive axle housing body employing at present mainly contains following form:
A kind of is releasable Drive axle housing body, is to be divided into two parts in left and right by a vertical engagement face, and each part outside has been provided with bridge tube grafting part, and its endoporus can be pressed into the axle tube assembly, forms left and right Drive axle housing assembly.Its major defect is that strength and stiffness are lower, and Drive axle housing body each several part and axle tube assembly weld or rivet simultaneously, and assembling, adjustment and maintenance are all very inconvenient.
Another kind be with final drive casing as the axle housing centre portion, both sides connect the bridge tube Plug Division and divide, there is removable bonnet rear end, this structure is higher to requirement on machining accuracy, ratio of rigidity is poor.
Summary of the invention
The purpose of this utility model is to provide a kind of cast type Drive axle housing body, and axle housing lightweight, simple in structure, easily manufactured reduces costs, and facilitates dismounting, adjustment, maintenance and the maintenance of main gearbox assembly.
The technical scheme that the utility model provides is as follows: comprise the axle housing main body, it is characterized in that: the axle housing main body is an integral body, rear portion arranges bonnet, front portion arranges the main reduction gear installing port, the flange that connects with final drive casing is set on installing port, axle housing main body both sides arrange has the axle tube grafting part of endoporus, in axle housing main body and axle tube grafting part junction, reinforced rib is set, and axle housing main body and two ends axle tube are pegged graft partly, bonnet is cast into one.
The utility model has the advantages that: reduced amount of parts, axle housing lightweight; Simple in structure, simplified processing and assembly technology flow process, be easy to guarantee working accuracy, easily manufactured, reduce costs; Can realize dismounting under the prerequisite of not dismantling whole bridge, adjust main gearbox assembly, make maintenance and maintain very convenient.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the assembly drowing of the utility model in the drive axle assembly.
The title at each position in figure: reinforced rib 1, bonnet 2, axle housing main body 3, axle tube grafting part 4, connecting flange 5, final drive casing 6, axle tube 7.
The specific embodiment
See Fig. 1, concrete structure of the present utility model is as follows: axle housing main body 3 is an integral body, and rear portion arranges bonnet 2; Front portion arranges the main reduction gear installing port, the flange 5 that connects with final drive casing 6 is set on installing port, axle housing main body 3 both sides arrange has the axle tube grafting part 4 of endoporus, in axle housing main body 3 and axle tube grafting part 4 junctions, reinforced rib 1 is set, the quantity of reinforced rib and geomery are determined according to the load that the drive axle assembly bears.Axle housing main body 3 is cast into one with two ends axle tube grafting part 4, bonnet 2.
See Fig. 2, during assembling Drive axle housing assembly, the final drive casing 6 of main gearbox assembly connects with axle housing main body 3 by connecting flange 5, and the endoporus of both sides axle tube grafting part 4 inserts axle tube 7 and welding.
