Abstract
The invention relates to a wheel-side speed reduction drive axle half shaft of a heavy truck and aims to provide a heavy truck wheel-side speed reduction drive axle half shaft which is light in weight, high in reliability, short in development cycle and low in cost. The wheel-side speed reduction drive axle half shaft comprises a hollow spindle and two spline shafts, one spline shaft is used for being connected with a wheel-side sun wheel, the other spline shaft is used for being connected with a differential half shaft gear, an outer wall of one end of each spline shaft is provided with a spline, the other end of the spline shaft is provided with a cavity and welded to one end of the hollow spindle, and the cavity is communicated with a cavity of the hollow spindle. Preferably, the diameter of the cavity at the end of the spline shaft is equal to that of the cavity in the hollow spindle. The hollow spindle and the two spline shafts are formed by No. 45 steel, the surfaces of the hollow spindle and the two spline shafts undergo quenching treatment, and the depth of a hardening layer is 6-11 mm. The invention further relates to a wheel-side assembly which comprises a hub, a brake drum, the drive axle half shaft, the sun wheel, a planet wheel and a wheel-side reduction casing.
Description
Technical field
The present invention relates to a kind of semi-axis structure, the wheel limit dual-ratio reduction device half shaft particularly on a kind of heavy duty truck.The invention still further relates to the wheel limit assembly of a kind of application this kind of half shaft.
Background technology
Wheel edge deceleration driving axle is widely used in heavy duty truck, and semiaxis is one of key components and parts realizing automotive operation, and its inner is connected with the axle side gear of diff, and Ze Yulun limit, outer end sun wheel connects.Under commercial vehicle/comm..vehicle weight-saving overall background, under meeting the prerequisite of load-carrying capacity requirement, weight is lighter more to have superiority, and existing half shaft mostly is solid construction, adopt one forging molding, its manufacturing development cycle is long, weight is comparatively large, and need more mold exchange when changing product, cost is higher.
Summary of the invention
For deficiency of the prior art, the present invention aims to provide a kind of lightweight, reliability is high, time-to-market is short, cost is low a kind of heavy duty truck wheel edge deceleration driving axle semiaxis.
In order to solve the problem, this kind of heavy duty truck wheel limit dual-ratio reduction device half shaft, it is characterized in that comprising: hollow spindle and two castellated shafts, a castellated shaft is used for being connected with wheel limit sun wheel, another castellated shaft is used for being connected with differential side gear, and the outer wall of one end of each castellated shaft is provided with spline, and the other end is provided with cavity, this end is welded with one end of hollow spindle, the cavity connects of its cavity and hollow spindle.
Preferably, the cavity diameter on described castellated shaft end is equal with the cavity diameter in hollow spindle.Described hollow spindle and two castellated shafts are made up of No. 45 steel, and its surface hardening process, hardened depth is 6 ~ 11mm.
The invention still further relates to a kind of wheel limit assembly, it comprises: wheel hub, brake wheel, half shaft, sun wheel, satellite gear and wheel limit subtract shell, it is characterized in that: described half shaft is half shaft described above, and the castellated shaft on this half shaft is connected with sun wheel.
The invention has the beneficial effects as follows: semiaxis of the present invention is formed by castellated shaft and welding hollow shaft.Half shaft length depends on hollow shaft length, and hollow shaft directly uses hollow tube manufacture, and do not need processing, length can select as required, time-to-market is short, cost of development is low.In addition, meet operating needs to improve comprehensive mechanical property, this hollow spindle and two castellated shafts are made up of No. 45 steel, and its surface hardening process, hardened depth is 6 ~ 11mm.
Accompanying drawing explanation
