Description
Technical field
The utility model relates to drive axle technical field, specifically a kind of loading machine drive axle.
Background technique
With the development of society, effect of the loading machine in economic construction is increasingly apparent, loading machine is often severe in operating condition
Environment in work, traditional dry brake during the work time can be because of the influence of environment, and braking effect decline is wet
Formula brake can overcome influence of the environment to braking effect.Existing drive axle subtracts serious wear, beats tooth, wet type system in the presence of master
Serious device friction disc wear, axle housing and support shaft weld is moved easily to occur to crack, have casting stress in the casting process of axle housing end
The defects of concentration, shrinkage cavity.
Therefore, it designs a can solve to overcome the shortcomings of above-mentioned technology and main subtract gear wear, plays the failures such as tooth and show
As improving the service life of wet brake, drive axle can be allow to bear bigger load, improving a kind of dress of working efficiency
Carrier aircraft drive axle, exactly inventor problem to be solved.
Utility model content
In view of the deficiencies of the prior art, the purpose of the utility model is to provide a kind of loading machine drive axle, it can solve master
Subtract gear wear, beat the failure phenomenons such as tooth, improve the service life of wet brake, drive axle can be allow to bear bigger bear
Lotus improves working efficiency.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of loading machine drive axle comprising wheel
Side reducer, wet brake, axle housing, main driving assembly, semiaxis, support shaft, wheel hub, main reducing gear, the semiaxis setting exist
Inside axle housing, the axle housing two sides are provided with hub reduction gear, the end rounding off of the axle housing, and the wet brake is set
It sets on semiaxis, the centre inside axle housing is arranged in the main driving assembly, and the main driving assembly passes through bolt and spring washer
Circle is tightly fastened with axle housing to be connect, and support shaft is provided on half shaft end, and the support shaft passes through stud and axle housing
Connection, the wet brake are connect with float grease seal, O-ring and wheel hub, and the wheel hub passes through stud and hub reduction
Device connection, and the junction of the wheel hub and hub reduction gear is provided with O-ring, the locking knot of the gear ring support and support shaft
Structure is double round nut and round nut stopping shim, and the gear ring support and support shaft pass through connection spline connection, the support shaft
Gear ring support junction is provided with centring sleeve, bearing, circular arc among the axle housing are provided between the wheel hub and support shaft
Be provided on face drain the oil it is stifled.
Further, reinforcing rib is provided in the axle housing otic placode.
Further, the main reducing gear is arranged in axle housing, and the main reducing gear uses castellated limited-slip differential.
The beneficial effects of the utility model are:
1, the utility model axle housing increases reinforcing rib, and intensity further increases；Rounding off at axle housing end cross-sectional, subtracts
While small wall thickness, stress concentration and casting flaw are avoided；It is fastenedly connected and is avoided using stud between support shaft and axle housing
The failure phenomenon of weld cracking；Castellated limited-slip differential guarantees that two side drive wheel rotating speed differences are allowed in a certain range.
