Abstract
The utility model discloses a four engine -drive axle assemblies in state, including preceding transmission shaft assembly, intermediate strut assembly and rear drive shaft assembly, the intermediate strut assembly is including wrapping up bracket, buffer block and bearing entirely, the buffer block is the annular, in wrapping up the bracket entirely surround annular outer lane, the bearing is installed in annular inner circle. Around the flange unified for the chinese industrial standards (CIS) 130, 140 interface flange, the cross axle still adopts 6500, 6700 structures of superior performance to adopt high rotational speed, non -maintaining bearing and corresponding sealed spare part. The utility model discloses be suitable for environmental protection, the moment of torsion of state no. 4, five engines in the state, each item requirement of rotational speed, the commonality is good, and succession nature is strong, and the security is high.
Description
Technical field
The utility model relates to a kind of vehicle driving shaft assembly, is specifically related to a kind of driving-shaft assembly meeting state four engine calls.
Background technology
Along with improving constantly that Chinese environmental protection requires, requirement according to national correlation department, all commercial car must use state four, the engine of state five standard, state four, state five engine are in addition to discharge standard height, owing to engine proposes shelves upgrading, the application of advanced technology, the moment of torsion of its engine, rotating speed all increase.No matter using original state three power transmission shaft all can not reach requirement from the relevant parameters such as moment of torsion.The technical property requirements that need to improve power transmission shaft for this, meets all technical of engine, the most effectively controls cost simultaneously, applies the technology succession of maturation as far as possible.State four power transmission shaft of this patent is developed jointly in Nanjing bridge power transmission shaft company and the cooperation of Shang Yan institute of DongFeng Automobile Co., Ltd..
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model is for state four, the feature of state five engine, it is provided that the vehicle driving shaft assembly that simple in construction, inheritance are good, versatility is high.
Technical scheme: for solving above-mentioned technical problem, the state four driving engine axle assembly that the utility model provides, including front propeller shaft assy., intermediate supports assembly and rear propeller shaft assy., described intermediate supports assembly includes entirely wrapping up bracket, buffer stopper and bearing, the outer ring of annular ringwise, is surrounded in described full parcel bracket by described buffer stopper, and described bearing is arranged in the inner ring of annular.
As preferably, between described bearing and buffer stopper, it is provided with bearing seal structure.
As preferably, the middle part of described front propeller shaft assy. has middle flange, and described middle flange couples with intermediate supports assembly.
As preferably, described rear propeller shaft assy. has central siphon, and described central siphon is shaped with splined shaft.
As preferably, described front propeller shaft assy. is coupled to each other by the flange yoke of end with rear propeller shaft assy..
As preferably, described buffer stopper is overall sulfuration damping rubber block.Rubber hardness can bear the requirement of 4000-5000 rev/min.
As preferably, described central siphon is the special central siphon of 440QZ power transmission shaft.
As preferably, the non-maintaining bearing of described Selection of Bearings.
Beneficial effect: the utility model meets state four, the requirement of state five engine, has simple in construction, technology uniformity, the feature of continuity, in the case of cost raising is limited, meets the technology requirement of new work engine, meets the technology coupling of car load.No matter and the power transmission shaft of the utility model design has all been made to promote and improve from structure, in performance, and ensureing the small size rising of power transmission shaft cost of manufacture.It is crucial that ensure driving-shaft assembly and gearbox, the uniformity of back axle interface.The switching surfaces of automobile main frame maker, assembly cost are greatly reduced.
In addition to the technical characteristic solving the technical problem that, constituting technical scheme except the utility model recited above and the advantage brought by the technical characteristic of these technical schemes, the advantage that the other technologies feature comprised in other technologies problem that state four of the present utility model driving engine axle assembly can solve, technical scheme and these technical characteristics bring, will be described in more detail in conjunction with accompanying drawing.

Detailed description of the invention
Embodiment:
The state four driving engine axle assembly of this enforcement includes front propeller shaft assy., intermediate supports assembly and rear propeller shaft assy., and wherein rear propeller shaft assy. is as depicted in figs. 1 and 2, including flange yoke 1, universal joint 2, splined shaft 3, central siphon 4.Front propeller shaft assy. and intermediate supports assembly as shown in Figure 3 and Figure 4, including flange 5, buffer stopper 6, wrap up bracket 8 entirely.Wherein buffer stopper 6 is ringwise, and the outer ring of annular, in Ω shape, is surrounded by full parcel bracket 8, and bearing 7 is arranged in the inner ring of annular.
During use, intermediate supports assembly is the full package structure of four pore area installation directions, overall sulfuration damping rubber block, and intermediate supports assembly inner bearing and sealing structure are satisfied by the requirement of High Rotation Speed；Rear propeller shaft assy. also uses the rear splined shaft that special thermal treatment controls outside the flange york containing front propeller shaft assy., central siphon uses the new material special central siphon of 440QZ power transmission shaft, while improving transmission shaft strength, it is ensured that the stability of material.
Universal joint uses novel cap universal joint assembly, quiet torsion intensity and fatigue strength to improve more than 30%.For improving uniformity, reducing replacement cost, development cost, front and back flange is unified is the 130 of Chinese Industrial Standards (CIS), 140 flanges, and cross axle still uses the 6500 of superior performance, 6700 structures.For ensureing high rotating speed, the reliability of power transmission shaft intermediate supports, use high rotating speed, non-maintaining bearing and seal parts accordingly.For adapting to new automobilism requirement, balancing speed requires at 4000r/min.Use band that the intermediate supports bracket of tandem is installed, it is ensured that the accuracy of power transmission shaft location.Use novel intermediate supports rubber, it is ensured that while intensity, change relevant rigidity, improve the regularity and stability that power transmission shaft runs.Meanwhile, special cubing is made.
Above in association with accompanying drawing, embodiment of the present utility model is described in detail, but the utility model is not limited to described embodiment.For those of ordinary skill in the art, in the range of principle of the present utility model and technological thought, these embodiments are carried out multiple change, revises, replace and deformation still falls within protection domain of the present utility model.
