The cross section in face is J-shaped structure, and the upper surface of the bottom steel plate is respectively welded the close to the top on the chamfering inclined-plane of both sides
The width at the middle part of side plate and the second side plate, first side plate and the second side plate be all higher than the width at both ends and with top bridge
The shape of top plate is adapted, and first side plate and the second side plate are welded with installation positioning plate between the edge of both ends, and
The middle part of two installation positioning plates is provided with location hole.
Preferably, the bottom steel plate and bridge top plate is of same size, and the first side plate and the second side plate are far from bottom steel
The side of plate is welded on bridge top plate lower surface on the chamfering inclined-plane of both sides.
Preferably, J-shaped inclined-plane is provided with, and two are installed positioning plate at the one side edge of two installation positioning plates
Top and bottom end are respectively welded on bridge top plate and bottom steel plate.
Preferably, the bridge top plate, bottom steel plate and two blocks of side plates are that low-alloy cut deal material is made, and cut deal
Thickness range be 20~50mm.
Preferably, the diameter of the location hole is less than the width of installation positioning plate, and the hole heart line of two location holes is located at
On same straight line.
The beneficial effects of the utility model are：By setting the side plate of cut deal material and top plate, bottom plate so that after molding
Structure " sturdy and durable ", " convenient for obtain ", " molding is quick ", " easy to process ", the characteristics such as " weldability is good "；Pass through setting point
The axle housing structure design of body formula, can effectively reduce Drive axle housing production cost, while meet product modular design and deformation
Design requirement；By set both ends install positioning plate design, both simplified the processing technology of axle housing, also for other parts
Combination assembling provide the Interface design of standardization, seriation；Welding procedure is both reduced by unilateral " J " type welding seam design
Difficulty, while can guarantee through welding property and weld strength again.
