Abstract
The utility model discloses a rear drive axle assembly of an engineering mechanical vehicle, which comprises an axle housing, a main speed reducer, a differential mechanism, a half shaft, a disc brake, a wheel hub reducer and a steering bracket assembly, wherein the disc brake can adopt a fixed caliper disc hydraulic brake, and the axle housing can adopt an integral axle housing. The rear drive axle assembly not only can be used as a non-steering drive axle when being not provided with the steering bracket assembly, but also can be used as a steering drive axle; and when the axle housing is arranged at one end of a flange through the main speed reducer for fixing position and transmitting power, and a convex cylindrical end of the axle housing is connected with the steering bracket assembly so as to realize the function of steering, the rear drive axle assembly is the steering drive axle.
Description
Technical field
The utility model relates to a kind of drive axle assembly, is specifically related to a kind of engineering machinery vehicle rear driving axle assembly.
Background technology
Traditional large-tonnage drives vehicle bridge (comprising front driving axle and rear driving axle), steering swivel all is housed when using as steeraxle, and the large-tonnage drive axle has relatively high expectations to the structure of steering swivel, intensity, rigidity etc., and this has just increased the difficulty of processing and the tooling cost of vehicle bridge.Present existing rear driving axle uses as steeraxle seldom separately, if use will have steering swivel as steeraxle, also not with the rear drive steeraxle of steering swivel, this has limited the vehicle operation performance to existing rear driving axle to a certain extent.
The utility model content
Technical problem to be solved in the utility model is that a kind of engineering machinery vehicle rear driving axle assembly that steering swivel just can be made steeraxle that need not will be provided.
For solving the problems of the technologies described above, the utility model rear driving axle assembly comprises axle housing, main reduction gear, diff, semiaxis, plate disc brake, wheel reduction gear, it is characterized in that, have the turning rack assembly on the rear driving axle assembly, the cylindrical end by the axle housing projection links to each other with the turning rack assembly.
Preferably, described main reduction gear bearing links to each other with axle housing by bolt, semiaxis links to each other with the sun wheel of differential side gear and wheel reduction gear by the two ends spline, the brake clamp of plate disc brake is by being bolted on the axle housing, brake disc is by being bolted on the wheel hub, and wheel hub links to each other with the pinion carrier of axle tube and wheel reduction gear respectively by bearing.
Preferably, plate disc brake adopts decides the caliper disc hydraulic brake, and simple in structure, cheap, deceleration and stopping performance is better;
Preferably, axle housing adopts integral axle housing, and compact conformation, rigidity of support is good, integrated universal is good, load-carrying capacity is strong.
The utility model novel structure, function is special, without steering swivel, by the function of special axle housing structure realization steeraxle, has been used for the model machine of the new-type loader drive axle assembly of our company's production at present.The utility model also can be used as the drive axle of other engineering machinery vehicle and large-tonnage overland vehicle, can simplify vehicle structure, improves reliability of products and economy.
Description of drawings
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is further described in detail.
