前面提过驱动桥壳采用整体式冲压焊接制造，主要是由于整体式桥壳强度和刚度

As mentioned above, the drive axle housing is manufactured by integral stamping and welding, mainly because the strength and rigidity of the integral axle housing are relatively large, and the main reducer is easy to disassemble and adjust. According to different manufacturing processes, the integral axle housing can be divided into three types, namely, stamping and welding type, expansion forming type and casting type. Axle shells manufactured by the two processes of stamping welding and expansion molding have low quality, high material utilization rate, low manufacturing cost, and are suitable for mass production. They are widely used in small cars and medium and small trucks, and some heavy trucks also use stamping The welding is the axle housing. The cast integral axle housing has high strength and stiffness, but the quality is large, the processing surface is many, and the manufacturing process is complicated. This axle housing is used in medium and heavy trucks.

The drive bridge shell mentioned earlier is manufactured by integral stamping welding, mainly because the strength and stiffness of the integral bridge shell are relatively large, and the main gearbox is easy to remove and adjust. According to the different manufacturing process, the whole bridge shell can be divided into three kinds, namely, stamping welding, expansion molding and casting. The bridge shell manufactured by the two processes of stamping welding and expansion molding is small in quality, high material utilization rate, low manufacturing cost, suitable for mass production, widely used in cars and small and medium-sized goods vehicles, and some heavy goods vehicles also use stamping welding is the bridge shell. Casting overall bridge shell strength and stiffness, but the quality, processing surface, manufacturing process is complex, this bridge shell is used in medium and heavy goods vehicles.

The driving axle housing mentioned above is made of integral stamping and welding, mainly because the strength and rigidity of the integral axle housing are relatively large, and the disassembly and adjustment of the main reducer is convenient. According to the different manufacturing process, the integral bridge shell can be divided into three types: stamping welding type, expansion molding type and casting type. The bridge shell manufactured by stamping welding and expanding forming processes has the advantages of low quality, high material utilization rate, low manufacturing cost, suitable for mass production, widely used in cars, medium and small trucks, and some heavy trucks also use stamping welding as the bridge shell. The cast integral bridge shell has large strength and rigidity, but it has large quality, many processing surfaces and complex manufacturing process. This kind of bridge shell is applied to medium and heavy trucks.<br>
