Description
Technical field
The utility model relates to a kind of driving bridge for engineering machinery, specifically a kind of driving axle for land leveller.
Background technology
Land leveller can be divided into four-wheel and six according to wheel quantity and take turns two kinds of forms, and four wheel grader is propons two-wheeled, back axle two-wheeled, and this form is mainly used in lightweight grader.Six-wheel grader is propons two-wheeled, back axle four-wheel, back axle transmission reaches four wheels by the tandem sequence device in the tandem-driving bogie of both sides by power, in the operation process of land leveller, in order to ensure the abundance of planarization and power of its perching knife scope of operation, tandem-driving bogie need to carry out a certain amount of swing around back axle axle center, so both can ensure that four tires of back axle grabbed ground adhesive power under various topographic features, also avoid some tires because the situation that causes car load to tilt after the former thereby perk of landform simultaneously.A novel driving axle for land leveller that the present invention develops for six-wheel grader just, at present, the operating principle of domestic the type driving axle for land leveller is similar, its structure is mainly divided into two kinds, a kind of is the middle integral housing that adopts monolithic construction, main drive gear is arranged on the centre of integral housing, two the power output axle shafts in left and right are connected with the duplex chain wheel in tandem-driving bogie, can power be passed to four trailing wheels by four groups of chain sprocket in tandem-driving bogie thus, then by passive sprocket shaft and planetary reduction gear, power be passed to four trailing wheels.Another kind adopts the axle housing of split-type structural in the middle of being, be characterized in that changing the former planetary reduction gear that is positioned at wheel position, limit into direct and middle main reducing gear is connected, planetary reduction gear housing and bevel housing are bolted, power is passed to planetary reduction gear by left and right semiaxis, power is passed to double strand chain wheel shaft by the mode of exporting by gear ring after planetary reduction gear, then by four groups of sprocket wheel chain drive structures, power is passed to four trailing wheels and directly carries out power output.Rear a kind of drive axle is that with respect to its advantage of the first drive axle axle housing adopts split-type structural, and planetary reduction gear is moved to bridge middle part by taking turns position, limit, and speed reducing ratio is successively decreased step by step, easy accessibility, and transmission is more steady, and wheel limit portion structure is simplified greatly.But above two kinds of bridge types all have two each and every one common shortcomings, one be exactly in the middle of the connection of axle housing and left and right tandem-driving bogie all adopt two groups of tapering bearings to be connected, on two groups of tapering bearing supporting portions outer panel for tandem-driving bogie, in order to ensure that tandem-driving bogie can swing according to the fluctuating of landform, between axle housing and tandem-driving bogie interior plate, install anti-wearing liner additional, this structure comes off because the problem of bearing quality easily causes tandem-driving bogie, and grows later anti-wearing liner service time because oil leakage phenomenon is easily caused at this position of reason of wearing and tearing.Another shortcoming is exactly that its wheel hub and power output shaft all adopt spline joint, fixes with bolt, easily occurs the problem that wheel hub comes off.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model re-starts structure design for the structural disadvantages of current domestic existing land leveller bridge type, solve that at present domestic existing bridge type tandem-driving bogie easily comes off, problem and the caducous problem of wheel hub of displacement and leakage of oil, thereby develop the novel driving axle for land leveller of a simple and reliable for structure, easy accessibility, function admirable.
To achieve these goals, the utility model is achieved through the following technical solutions: a kind of driving axle for land leveller, comprise main reducing gear, differential mechanism, main gearbox assembly, jackshaft, planetary gear assy, planetary reducer, double strand chain wheel shaft, pivoting support, tandem-driving bogie, duplex chain wheel, chain, sprocket wheel, brake assembly, wheel hub and power output shaft, the main gearbox assembly of main reducing gear and differential mechanism composition; The planetary gear assy of jackshaft, planetary reducer and double strand chain wheel shaft composition; The power output shaft of pivoting support, tandem-driving bogie, duplex chain wheel, chain, sprocket wheel and power output shaft and wheel hub composition, wherein power output shaft and wheel hub are monolithic construction, sprocket wheel and power output shaft are bolted.
Described planetary gear assy is connected by pivoting support with tandem-driving bogie, and pivoting support outer ring is connected with tandem-driving bogie bolt, and pivoting support inner ring is connected with planetary gear assy shell bolt, and tandem-driving bogie and brake assembly are bolted.
Described main gearbox assembly and planetary gear assy shell are bolted.
The beneficial effects of the utility model are: middle axle housing adopts pivoting support to connect with being connected of tandem-driving bogie, and pivoting support outer ring is connected with tandem-driving bogie inner side, and inner ring is connected with middle axle housing, cancels original anti-wearing liner and self-aligning bearing.Pivoting support Internal and external cycle can relatively rotate, itself and axle housing and tandem-driving bogie casing connecting portion adopt O type circle and fluid sealant to seal, for static seal, with respect to self-aligning bearing, the supporting capacity of pivoting support strengthens greatly, so both ensured that tandem-driving bogie can not be shifted, come off, strengthen the reliability connecting, solve again the problem of the easy leakage of oil of connecting portion in the situation that tandem-driving bogie constantly swings, secondly cancel self-aligning bearing, reduce casing and processed the requirement to axiality, it is more easily simple that casing processing becomes, simplify the complexity of whole bridge assembling simultaneously, wheel position, limit power output shaft and wheel hub adopt overall structure, cancel spline joint, the fixing structure of bolt, brake and wheel hub and sprocket wheel entirety are bolted with tandem-driving bogie after being assembled into a brake assembly, so not only ensure the reliability of its braking, the problem of simultaneously having avoided wheel hub to come off because of bolt looseness, secondly adopts this form of brake assembly to decide and to adopt dry type or wet braking according to user's different demands easily.
