Abstract
The invention relates to a flat car drive axle of a hydraulic drive motor, which comprises a drive axle body and a hydraulic motor, wherein the hydraulic motor is externally connected with the drive axle body; the drive axle body comprises a differential mechanism, a semi-axle body and a reduction gear, wherein the semi-axle body is in drive connection with the differential mechanism; the reduction gear is in drive connection with the semi-axle body; the differential mechanism is in drive connection with the hydraulic motor; the reduction gear is in drive connection with a rim of a flat car; the outer part of the semi-axle body is provided with a wheel axle; and the differential mechanism and the reduction gear are connected into a whole by the wheel axle. In the flat car drive axle, the differential mechanism, the wheel axle and the reduction gear are integrally arranged, and therefore, the whole drive axle body is convenient to produce, install, repair and maintain.
Description
Technical field
The present invention relates to a kind of flat truck drive axle that is applicable to the big part of carrying, particularly relate to a kind of flat truck drive axle with independent hydraulically controlled motor.
Background technology
At present, the used drive axle of known flat truck mainly is split type, and it mainly contains parts and parts such as wheel axis body, HM Hydraulic Motor, wheel side speed reducer, terminal pad, and all parts assemble through Bolt Connection.Though the function of the required realization of drive axle is identical, the complex structure of split type drive axle, difficult installation, parts are many, and reliability is low, and is difficult in maintenance, thereby also gives the hydraulic efficiency pressure system and the electric system that connect with it complicated.
Summary of the invention
The object of the invention provides a kind of flat truck drive axle of hydraulic drive motor.
For achieving the above object, the technical scheme that the present invention adopts is:
A kind of flat truck drive axle of hydraulic drive motor; The HM Hydraulic Motor that comprises the drive axle body, outreaches mutually with described drive axle body; The semiaxis body that described drive axle body comprises diff, be in transmission connection with described diff mutually, the reductor that is in transmission connection mutually with described semiaxis body; Described diff is in transmission connection with HM Hydraulic Motor mutually; Described reductor is in transmission connection with the wheel rim of flat truck mutually, and described semiaxis external is provided with wheel shaft, and described wheel shaft connects as one described diff and reductor.
Preferably, described semiaxis is a fully floating axle.
Preferably, be provided with the one-level speed reduction gearing between described HM Hydraulic Motor and the diff, described one-level speed reduction gearing is provided with a pair of spur wheel.
Preferably, described diff is provided with double reduction gear, and described double reduction gear is provided with a pair of spiral bevel.
Preferably, described reductor is a wheel side speed reducer, and described wheel side speed reducer is provided with three planetary wheels.
Because the technique scheme utilization, the present invention compared with prior art has advantage and effect: the present invention makes the convenient production of whole drive axle body, installs and maintenance through diff, wheel shaft and reductor are wholely set.
Description of drawings
Accompanying drawing 1 is a front view of the present invention;
Accompanying drawing 2 is a birds-eye view of the present invention.
Wherein: 1, drive axle body 2, HM Hydraulic Motor 3, diff 4, wheel shaft 5, reductor.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Like the flat truck drive axle of Fig. 1, a kind of hydraulic drive motor shown in 2, the HM Hydraulic Motor 2 that comprises drive axle body 1, outreaches mutually with drive axle body 1.Wherein: the semiaxis body that drive axle body 1 comprises diff 3, be in transmission connection with diff 3 mutually, the reductor 5 that is in transmission connection mutually with the semiaxis body; The semiaxis body comprises left and right two semiaxis that are used for left and right two wheels of transmission; Two semiaxis are connected with reductor 5 respectively; In the present embodiment, semiaxis adopts fully floating axle, and reductor adopts wheel side speed reducer.Diff 3 is in transmission connection with HM Hydraulic Motor 2 mutually, and reductor 5 is in transmission connection with the wheel rim of flat truck mutually.
Be provided with wheel shaft 4 in the semiaxis external, wheel shaft 4 connects as one diff 3 and reductor 5.
In the present embodiment, drive axle is provided with three grades of reduction gear apparatuss.Wherein: the one-level speed reduction gearing is arranged between HM Hydraulic Motor 2 and the diff 2, mainly adopts a pair of spur wheel; Double reduction gear is arranged in the diff 3, mainly adopts a pair of spiral bevel; Triple reduction gearing is wheel side speed reducer, mainly adopts three planetary wheels.Double reduction gear in three grades of reduction gear apparatuss is main gear down device in the present embodiment, makes drive axle have driving efficiency height, reliable transmission like this, and overall performance is good, exports characteristics such as steady.
When drive axle carries out work: a CD-ROM drive motor at first need be installed; After the deceleration of the output torque of CD-ROM drive motor through one-level speed reduction gearing and double reduction gear; Further carry out differential through diff; Pass to the wheel side speed reducer of both sides behind the differential respectively through left and right half, wheel side speed reducer drives wheel rim through triple reduction gearing, and wheel rim can tire on the drive wheels be a vehicle to run.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
