Abstract
The utility model relates to a framework for a planetary gear speed reducing mechanism, which mainly aims to solve the problems that a welding framework and the integral casting framework of a small positioning spigot are deficient, and the obtained sufficient supporting intensity and the length of the integral framework are limited; the framework accordingly adopts the technical proposal that the integral casting framework is adopted, the appearance of the framework adopts a cylindrical shape, and one end surface of the framework adopts an inner flange surface; an outer flange surface is arranged on the other end surface of the framework; the inner flange surface serves as a supporting point of the gear of the planetary reducing mechanism, and the outer flange surface serves as a connecting surface connected with a wheel hub; the inner cavity of the framework is the space for holding the planetary speed reducing mechanism, inner positioning spigots of the wheel hub are arranged at the opening part of the framework, the connecting flange of the framework is positioned between a brake drum and the wheel hub to ensure the closer matching relation among the spigots, and the spigots are fixed by car wheel bolts.
Description
Technical field
The utility model relates to a kind of planetary gear reducing mechanism framework.
Background technique
At present, in the general arrangement of heavy truck, large-bus, for make assemblies such as gearbox, transfer case, transmission shaft not reason bear excessive torque and make their size and quality excessive, can distribute to ransaxle by the ratio that velocity ratio is big as far as possible, inaccessible this requirement of main reducing gear of general structure, therefore many heavy-duty cars, large-bus often adopt the structure of single-stage (or twin-stage) main reducing gear additional wheel side reducer, a part of reduction speed ratio of ransaxle is distributed to be installed in wheel hub centre or wheel reductor nearby.Thereby obtain bigger ratio coverage and the good performance of passing through.
And at present hub reduction ransaxle wheel reductor framework generally adopts is the 3 stops welded structure, because of the restriction of welding with material, causes the support strength deficiency of welded framework to planetary gear speed reducing mechanism, and gear transmission torque scope seriously is affected; After more seriously causing taking turns the assembling of heel teeth spoke, the gear engagement precision is difficult to guarantee that heating is serious, and wheel end temperature is high, has a strong impact on gear lubrication and causes the life-span to be reduced, and increases maintenance cost.Weld in addition that yielding to cause welding back machining allowance excessive, reduce the utilization efficiency of blank, the relative ad eundem steel of welding consumables cost costliness also is the higher reason of lead frame cost simultaneously.Another structure is to adopt small end face, the integral frame of short seam location, because of end face is little, positioning spigot is short, and framework is restricted after all to the strength support ability of wheel end tooth wheel, so the framework axial length can not be long, under wide certain situation, wheelspan must more approach outer wide, causes axle housing under the situation of bearing same load outside the axle assembly maximum, moment of flexure is bigger, influences the axle housing life-span.
Summary of the invention
The purpose of this utility model is can guarantee to take turns the layout of limit planetary gear reducing mechanism in the ransaxle assembly to obtain enough support strengths, solve the deficiency of lead frame and little positioning spigot cast inblock framework, effectively solve the problem of integral frame length limited, install, dismantle, safeguard for hub reduction mechanism can be used as an integral module.
For addressing the above problem, its technological scheme is: the planetary gear reducing mechanism framework provides being connected of planetary gear reducing mechanism and ransaxle other parts, be characterised in that: adopt the cast inblock framework, the profile of framework is cylindric, and an end face of framework is the inner flange face; The other end opening of framework, opening is provided with the outward flange face; The inner flange face is the strong point of planetary gear speed reducing mechanism, and the outward flange face is the junction surface that is connected with wheel hub; The inner chamber of framework is the space that holds planetary gear speed reducing mechanism, and the opening of framework is provided with the interior positioning spigot of wheel hub.
Beneficial effect:
The utility model can guarantee to take turns the layout of limit planetary gear reducing mechanism in the ransaxle assembly and obtain enough support strengths, install for hub reduction mechanism can be used as an integral module, dismantle, safeguard provide may, significantly improve the application area of car load and, cost is reduced by performance; The outward flange face of framework is between brake drum and wheel hub, and is fastening with wheel bolt, and it is more reliable that this Placement cooperates internal and external stopper, when improving the whole support strength of wheel end, also solved the limited problem of lengths of frame.
