Improved axle housing assembly of steering drive axle for special vehicle

Abstract

An improved axle housing assembly of a steering drive axle for a special vehicle comprises a left steering knuckle supporting seat assembly, lower steel plate spring seats, upper steel plate spring seats, an axle housing body, positioning pin seats, an oil baffle plate, a booster cylinder support, an oil guide groove, limiting seats and a right steering knuckle supporting seat assembly which are fixedly connected with one another. The axle housing body, the left steering knuckle supporting seat assembly and the right steering knuckle supporting seat assembly are in transition fit with one another via inner seam allowance and outer seam allowance and are connected with one another by connecting bolts and spring washers, and the lower steel plate spring seats, the upper steel plate spring seats, the positioning pin seats, the oil baffle plate, the booster cylinder support, the oil guide groove, the limiting seats and the axle housing body are welded with one another. A left steering knuckle supporting seat body, a right steering knuckle supporting seat body and a connecting flange are formed by means of forging. The improved axle housing assembly has the advantages that shortcomings of long development cycle and high development die cost of a special vehicle axle are overcome while service requirements are met, the improved axle housing assembly is easy to modify to be serialized, and accordingly market change requirements can be quickly met.

Description

technical field [0001] The invention relates to an improved steering drive axle assembly for a special vehicle, in particular to an improved axle housing assembly structure for a non-disconnected steering drive axle of a heavy special vehicle and a military off-road vehicle. Background technique [0002] Heavy-duty special vehicles and military off-road special vehicles are required to have the characteristics of adapting to harsh road environments and field driving, and have high requirements for the matching of the whole vehicle, especially the high strength and rigidity of the axle housing assembly, so as to ensure that the vehicle chassis bearing capacity and impact performance. In addition, due to the different purposes and environments of special vehicles, each has different requirements for the complete vehicle, and the status of the vehicle model changes frequently. Generally, it is impossible to mass-produce a certain type of axle, so the mold of the axle housing bo...

Problems solved by technology

In addition, due to the different uses and environments of special vehicles, each has different requirements for the complete vehicle, and the state of the vehicle model changes frequently. Generally, it is impossible to mass-produce a certain type of axle, so the mold of the axle housing body often changes.

Therefore, at present, this type of stamped and welded axle housing assembly and cast steel axle housing assembly adopt the manufacturing method of welding the steering knuckle support seat and the axle housing body as a whole, which is not good in manufacturability and poor in versatility.
