Abstract
The utility model relates to an automobile drive axle main speed reducer shell and aims at providing a low-cost, light-weight, good-casting and good-diathermancy drive axle main speed reducer shell. The automobile drive axle main speed reducer shell comprises a bearing block junction surface arranged at the upper part of the shell and a flange ring arranged at the lower part of the shell, wherein the flange ring is provided with a plurality of connecting holes; the section of the bearing block junction surface is of a round shape with uniform bosses, each round boss is provided with a bolt hole; preferably, the quantity of the bolt holes is 5-12; the bolt holes are distributed on a round surface with the diameter of 200-260mm; the wall thickness of each part of the shell is equal and is 5-8mm; multiple reinforced ribs are arranged between the bearing block junction surface and the flange ring; the thickness of each reinforced rib is 5-15mm; multiple bosses are arranged along the outer edge of the flange ring in an extending manner and are uniformly distributed along the circumferential direction of the flange ring.
Description
Technical field
The utility model relates to a kind of improvement of shell construction, particularly the bevel housing on a kind of automobile drive axle.
Background technique
At present, heavy truck, Passenger Vehicle be widely used in highway transport and engineering transportation, vehicle bridge is as the crucial assembly of bearing load and carry-over moment, its bearing capacity has determined the bearing capacity of car load, and himself weight affects the Economy requirements such as the lightweight of car load and oil consumption.Under the light-weighted overall background of commercial car, meet under the prerequisite of bearing capacity requirement, product weight gently can make it in violent market competition, account for and have great advantage.And in current vehicle bridge product, the problem that final drive casing is bigger than normal as main housing ubiquity weight, structure is heavy, affects the Economy of car load.
Model utility content
For deficiency of the prior art, the utility model aims to provide the main reducing gear of drive axle housing that a kind of cost is low, lightweight, casting manufacturability is good, diathermancy is good.
In order to address the above problem, this kind of automobile drive axle main reducing gear shell body, comprise and be arranged on the bearing support junction surface on housing top and the flange ring that is arranged on lower housing portion, this flange ring is provided with some attachment holes, it is characterized in that: the cross section of this bearing support junction surface is the circle with even boss, and this each circular boss is provided with a bolt hole.
Preferably, the quantity of described bolt hole is 5～12, and this bolt hole is distributed on a disc, and this disc diameter is 200～260mm.
Preferably, the wall thickness of described housing each several part is impartial, and this wall thickness is 5～8mm.
Preferably, between described bearing support junction surface and flange ring, be provided with many stiffening ribs, and the thickness of this stiffening rib is 5～15mm.
More preferably, along described flange ring outer rim, extended a plurality of boss, this boss is circumferentially evenly arranged along flange ring.
The beneficial effects of the utility model are:
1, to be designed to class petal-shaped with bearing support junction surface profile, saved to greatest extent material, alleviated the weight of final drive casing, reached light-weighted object.
2, the wall thickness such as final drive casing housing employing design, in the situation that meeting intensity, reduce main wall thick, makes diathermancy better in the time of weight reduction.
3, final drive casing inner chamber, in the situation that meeting function requirement, dwindles substantially main cavity and contains volume.Reduce further weight, main wall adopts Rouno Cormer Pregrinding Wheel transition structure simultaneously, helps and improves stress and casting manufacturability;
4, between guide bearing chock and large face, increase supporting rib, meet the demand of integral rigidity.
5, large of flange, locate to stretch out some boss, be convenient to main reducing gear dismounting.
Accompanying drawing explanation
Fig. 1 is the perspective view of automobile drive axle main reducing gear shell body of the present utility model;
Fig. 2 is the plan structure schematic diagram of automobile drive axle main reducing gear shell body of the present utility model;
Fig. 3 is the sectional structure schematic diagram of automobile drive axle main reducing gear shell body of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
In conjunction with Fig. 1 to Fig. 3, this kind of automobile drive axle main reducing gear shell body, comprise and be arranged on the bearing support junction surface on housing top and the flange ring that is arranged on lower housing portion, this flange ring is provided with a circle attachment hole, the cross section a of this bearing support junction surface is roughly with the circle of even boss, and this each circular boss is provided with a bolt hole.This structure, in the situation that meeting casing rigidity and bolt hole spatial requirement, has been saved material to greatest extent, has alleviated the weight of final drive casing, has reached light-weighted object.The quantity of described bolt hole is 5～12, and this bolt hole is distributed on a disc, and this disc diameter is 200～260mm.
The wall thickness of described housing each several part is impartial, and this wall thickness is 5～15mm.More traditional shell main wall thick attenuate 1～2mm that subtracts, has reduced the weight of housing effectively, has reduced the unsprung weight of car load in the time of cost-saving; Attenuate wall thickness, the heat of lubricant oil can be delivered to housing outer surface quickly in housing, thermal diffusivity is better.
At bearing support junction surface and flange ring, be provided with many stiffening ribs 1, this stiffening rib 1 extends to outside by enclosure interior, and the thickness of this stiffening rib is 5～15mm.By increase supporting rib between bearing support and large face, meet the demand of integral rigidity, in addition, in order to meet the intensity of final drive casing and to strengthen its integral rigidity, hull outside has also designed stiffening rib, the stiffening rib in outside has increased the outer surface of whole housing simultaneously, contributes to housing outwards to dispel the heat.In flange ring outer rim, a plurality of boss 2 have been extended, this boss 2 being circumferentially evenly arranged along flange ring.Be convenient to main reducing gear dismounting.
