Abstract
The utility model relates to a drive rear axle for engineering machinery, which comprises a parking brake assembly, a driving gear and a rear axle shell. A speed reducer box is arranged in the middle in the rear axle shell, a speed reducer assembly is arranged in the speed reducer box, the left side and the right side of the speed reducer assembly are respectively provided with a wet type brake assembly, the left side and the right side of the wet type brake assemblies are respectively provided with an axle shell, and the two ends of the axle shells are respectively provided with a hub speed reducer. By directly adopting the split casting process, no processing is needed after welding, the processing is simplified, the production cost is reduced, and the passing rate of the product is increased.
Description
Technical field
The utility model belongs to construction machinery and equipment manufacturing technology field, is specifically related to the driving rear axle that a kind of construction machinery and equipment is used.
Background technology
At present, it is foundry goods that the driving rear axle great majority of the construction machinery and equipment of domestic production adopt centre portion, the two sides spindle nose partly adopts welding, postwelding processing is like this because post welding distortion needs secondary processing, difficulty of processing is big, the bad assurance of axle bearing hole, two sides concentricity, therefore, greatly reduce service life; External plate disc brake, complex structure, volume be big, difficulty, poor reliability are installed; The wheel reduction gear planetary wheel carrier adopts split type, complex structure, mounting process complexity, thus also increased cost and fragile, also bring very big difficulty for maintenance.Foundry goods and machine up assembly welding structure, yielding, the processing technology complexity, volume is big, brings bigger difficulty to processing and manufacturing, and simultaneously, the weight of axle housing is big, also brings certain difficulty for the assembling of drive axle; External plate disc brake, complex structure, volume be big, difficulty, poor reliability are installed; The split type limit planetary wheel carrier of taking turns, complex structure is installed difficulty, welded type rigidity mounting bracket, bearing capacity is poor, and is yielding, safety is bad, no holding brake device.
Summary of the invention
The utility model has overcome the deficiencies in the prior art, has proposed the driving rear axle that a kind of construction machinery and equipment is used, and described driving rear axle directly adopts divided casting technology, do not need to weld back processing, oversimplify processing technology, thereby reduced productive costs, improved the qualification rate of product; Built-in oil-immersed multi-disk brake, lock torque is big, and good reliability is safe, and is non-maintaining, reduced maintenance difficulty; Install simple, not fragile; Rigidity mounting bracket and axle housing are cast as one, and bearing capacity is big, is out of shape for a short time, and safety and reliability increases Parking Brake, directly brakes driving tooth, and is safer during parking.
The technical solution of the utility model is: the driving rear axle that a kind of construction machinery and equipment is used, comprise parking brake assembly, driving tooth and rear axle housing body, be provided with reduction case in described rear axle housing body bosom position, in described reduction case, be provided with speed reducer assembly, one cover oil-immersed multi-disk brake assembly respectively is set in the right and left position of described speed reducer assembly, described oil-immersed multi-disk brake assembly the right and left position respectively is provided with an axle housing, and described axle housing two ends respectively are provided with a cover wheel reduction gear.
Be provided with differential assembly in described speed reducer assembly inside.
Respectively be provided with semiaxis in described differential assembly the right and left position, described semiaxis links to each other with wheel reduction gear.
Described driving tooth is provided with brake disc.
Described parking brake assembly is installed in the input end of driving tooth.
The utlity model has following beneficial effect:
1) the utility model compact conformation, safety, good reliability;
2) the utility model adopts oil-immersed multi-disk brake, and lock torque is big, and is non-maintaining;
3) the utility model is easy for installation simple, reduces maintenance, long service life.
