Abstract
The invention discloses a connection structure for a main speed reducer and an axle housing of a heavy vehicle drive axle. The connection structure at least comprises the main speed reducer and the axle housing, wherein a plurality of first installation through holes for cooperating installation and detachment are formed in the edge of the main speed reducer, and the main speed reducer is connected with the axle housing through fixing bolts; second installation through holes are formed at positions corresponding to the first installation through holes of the main speed reducer, on the axle housing; at least one backing plate is further arranged in the axle housing; third installation through holes are also formed at positions corresponding to the second installation through holes, on the backing plate; the fixing bolts penetrate through the third installation through holes of the backing plate, the second installation through holes of the axle housing and the first installation through holes of the main speed reducer, and match with fixing nuts. When the drive axle has a too high load and the fixing bolts are broken, the whole backing plate can be detached from the axle housing, and use of the axle housing cannot be influenced, so that the maintenance difficulty of equipment after faults of the drive axle is reduced, and the use cost of the drive axle can also be greatly reduced.
Description
Technical field
The present invention relates to a kind of main reduction gear and axle housing connection structure of heavy-duty vehicle drive axle.
Background technology
Driving axle of heavy automobile is except having except wheel transferring power, also has the effect by axle housing carrying carload, and main reduction gear and axle housing junction have stress to concentrate, this just requires that connecting device wants reliably fastening, but the problem of heavy motor vehicle ubiquity overload at present, the bolt connected inevitably ruptures, and post-rift bolt is retained in axle housing tapped bore, causes axle housing to scrap.
Summary of the invention
Technical matters to be solved by this invention is to provide main reduction gear and the axle housing connection structure of the heavy-duty vehicle drive axle that a kind of structure is simple, result of use is good.
For solving the problems of the technologies described above, the invention provides a kind of main reduction gear and axle housing connection structure of heavy-duty vehicle drive axle, at least comprise main reduction gear and axle housing, main reduction gear edge has some the first installation through holes coordinating handling, is connected between main reduction gear and axle housing by bolt of rear end plate;
First of the corresponding main reduction gear of axle housing is installed lead to the hole site and is had the second installation through hole, at least one backing plate is also provided with in axle housing, described backing plate correspondence second is installed lead to the hole site and is also had some 3rd installation through holes, and bolt of rear end plate runs through the 3rd of backing plate to be installed through hole, the second installation through hole of axle housing and the first installation through hole of main reduction gear and coordinates with captive nut.
After adopting such structure, when the excessive bolt of rear end plate fracture of drive axle load, whole backing plate can disassemble from axle housing, the use of axle housing is not affected, after reducing drive axle et out of order, the maintenance difficulty of equipment, also can reduce the use cost of drive axle greatly.
Technology contents for a better understanding of the present invention, below by the main reduction gear of this heavy-duty vehicle drive axle and axle housing connection structure referred to as this connection structure.
This connection structure also comprises ring stiffener, and ring stiffener is arranged between main reduction gear and axle housing, and ring stiffener is installed lead to the hole site at first of corresponding main reduction gear and had through hole; After adopting such structure, ring stiffener can strengthen the stability connected between main reduction gear and axle housing.
The screw rod of the bolt of rear end plate of this connection structure runs through the 3rd installation through hole of backing plate successively, second of axle housing installs through hole, the through hole of ring stiffener, the first installation through hole of main reduction gear coordinate with bolt of rear end plate, and the head of described bolt of rear end plate welds with backing plate.
Also fixed by caging bolt between the backing plate of this connection structure and axle housing.
The quantity of the backing plate of this connection structure is two, is upper padding plate and lower bolster respectively.
Accompanying drawing explanation
Fig. 1 is the exploded perspective view of this connection structure embodiment.
Fig. 2 is the structural representation of this connection structure embodiment upper padding plate and bolt of rear end plate.
Fig. 3 is the birds-eye view of Fig. 2.
Detailed description of the invention
(owing to only illustrating lower bolster in visual angle cause chart 1, upper padding plate is not shown) as shown in Figures 1 to 3
This connection structure comprises main reduction gear 1, ring stiffener 2 and axle housing 3.
Main reduction gear 1 edge has 12 first and installs through hole 11, and ring stiffener 2 is installed through hole 11 position at first of corresponding main reduction gear 1 and had through hole 21.
First of the corresponding main reduction gear 1 of axle housing 3 is installed through hole 11 position and is had 12 second installation through holes 31, and axle housing 3 also has 32, four the spacing hole 32 upper and lower distributions between two of four spacing holes; Two circular arc backing plates are also provided with in axle housing 3, upper padding plate 41 and lower bolster 42 (upper padding plate 41 is substantially identical with using method with the structure of lower bolster 42) respectively, upper padding plate 41 and the upper and lower layout of lower bolster 42, and upper padding plate 41 and lower bolster 42 form main reduction gear 1 edge shape that coincide substantially, upper padding plate 41 and lower bolster 42 corresponding second are installed through hole 31 position and are had six the 3rd and install through holes 43 respectively, and on upper padding plate 41 and lower bolster 42 respectively corresponding spacing hole 32 position have two spacing tapped bore 44.
The screw rod of 12 bolt of rear end plates 5 be corresponding in turn to run through the 3rd of backing plate install through hole 43, axle housing 3 second through hole 31, the through hole 21 of ring stiffener 2, first the installing through hole 11 and coordinate with captive nut 7 of main reduction gear 1 are installed, the head of each bolt of rear end plate 5 welds with backing plate.
The spacing tapped bore 44 of Liang Ge spacing hole 32 and upper padding plate 41 that two caging bolts 6 run through axle housing 3 respectively coordinates, upper padding plate 41 and axle housing 3 are fixed, the spacing tapped bore 44 of Liang Ge spacing hole 32 and lower bolster 42 that two other caging bolt 6 runs through axle housing 3 respectively coordinates, and lower bolster 42 and axle housing 3 is fixed.
During use, when the excessive bolt of rear end plate 5 of drive axle load ruptures, whole backing plate can disassemble from axle housing 3, the use of axle housing 3 is not affected, after reducing drive axle et out of order, the maintenance difficulty of equipment, also can reduce the use cost of drive axle greatly.
Above-described is only one embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, under the premise without departing from the principles of the invention, can also make some modification and improvement, and these also should be considered as belonging to protection scope of the present invention.
