Abstract
The invention discloses a car transmission shaft assembly. The car transmission shaft assembly comprises a hollow shaft tube (5). The inner wall of the shaft tube is uneven. The front end of the shaft tube (5) is connected with a universal joint (1) through a front U-shaped fork (4). The rear end of the shaft tube (5) is connected with a rear axle main reduction end face flange (3) through a rear U-shaped fork (6). Rolled paper (7) is placed along the inner wall surface of the shaft tube (5) in a flat attaching mode. Due to the fact that the rolled paper is placed along the inner wall surface of the shaft tube in the flat attaching mode, when a car runs at high speed, high-speed airflow rapidly enters the shaft tube which rotates at high speed through the side face of the front U-shaped fork from a gap of the welding position, intense friction and impact are not generated between the airflow and the uneven inner wall of the shaft tube any more due to blocking and absorption of the rolled paper in the shaft tube, purr whine noise generated by the high-speed airflow can be greatly lowered, noise is low and can not interfere in listening of a driver to other sounds, and therefore the operation of the driver for normally driving the car can not be affected, and normal running of the car is guaranteed.
Description
Technical field
The present invention relates to automobile chassis drive system system, be specifically related to a kind of vehicle driving shaft assembly.
Background technology
Driving-shaft assembly is as the pass heavy mail in driving system, most important to normally travelling of automobile.As depicted in figs. 1 and 2, existing a kind of vehicle driving shaft assembly 2, the inwall of its central siphon 5 is rough and uneven in surface shape, and the front end of central siphon 5 is welded to connect with universal-joint 1 by front U-shaped fork 4, and its rear end subtracts end face flange 3 by rear U-shaped fork 6 with back axle master and is welded to connect.The technical matters that this vehicle driving shaft assembly exists is: central siphon 5 is welded to connect with universal-joint 1 by front U-shaped fork 4, weld has gap conventionally, when galloping, high velocity air by rapidly from the gap of weld by the side of U-shaped fork 4 enter the central siphon 5 of high speed rotating, through central siphon 5, from rear U-shaped fork 6 sides, pass again, because central siphon 5 inwalls are rough and uneven in surface shape, high velocity air is after entering rapidly central siphon 5, be there is to fierce friction and impact in the inwall of shape rough and uneven in surface with it, produce " toot " whistler, seriously disturbing influence the hearing of navigating mate to other sound, and then may affect navigating mate to automobile normal driving.
Summary of the invention
The technical problem to be solved in the present invention is to provide the vehicle driving shaft assembly that a kind of noise is less.
For solving the problems of the technologies described above, the present invention takes following technical scheme;
Vehicle driving shaft assembly of the present invention, the central siphon that comprises hollow, its inwall is rough and uneven in surface shape, and the front end of described central siphon is welded to connect by front U-shaped fork and universal-joint, and its rear end subtracts end face flange by rear U-shaped fork and back axle master and is welded to connect: described central siphon is along the smooth placement web-like of internal face paper.
Preferably, described web-like paper thickness is 2.5mm soil 0.20mm.
Preferably, described web-like paper transverse tensile strength is not less than 37kN/m.
Preferably, described web-like paper cross direction elongation is not less than 5.5%.
Preferably, described web-like paper ash divides and is not more than 2.0%.
Preferably, the thickness of described web-like paper and surperficial villus length uniformity.
Preferably, the surface of described web-like paper does not have pleat, crackle, bulge.
Compared with prior art, the present invention comprises following beneficial effect;
By central siphon along the smooth placement web-like of internal face paper, when galloping, high velocity air rapidly from the gap of weld by the side of U-shaped fork enter the central siphon of high speed rotating, it is subject to obstruct and the absorption of the involute official form for filing a lawsuit of central siphon, just no longer there is fierce friction and impact with the inwall of the rough and uneven in surface shape of central siphon, high velocity air produce " toot " utter long and high-pitched sounds and will greatly reduce, noise is very little, this just can the hearing of disturbing influence navigating mate to other sound, and then also just can not affect navigating mate to automobile normal driving, thereby guarantee automobile normal running.
Accompanying drawing explanation
Fig. 1 is the vehicle driving shaft assembly structural representation of prior art;
Fig. 2 is the decomposing schematic representation of central siphon, front U-shaped fork and rear U-shaped fork;
Fig. 3 is structural representation of the present invention;
Fig. 4 is that central siphon is along the local enlarged diagram of the smooth placement web-like of internal face paper.
In figure, U-shaped fork, 7-web-like paper after 1-universal-joint, 2-driving-shaft assembly, 3-flange, the front U-shaped fork of 4-, 5-central siphon, 6-.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail;
Referring to Fig. 3 and Fig. 4, vehicle driving shaft assembly of the present invention, the central siphon 5 that comprises hollow, its inwall is rough and uneven in surface shape, the front end of described central siphon 5 is welded to connect with universal-joint 1 by front U-shaped fork 4, its rear end subtracts end face flange 3 by rear U-shaped fork 6 with back axle master and is welded to connect: from Fig. 3 and Fig. 4, and vehicle driving shaft assembly of the present invention, described central siphon 5 is along the smooth placement web-like of internal face paper 7.Because described central siphon 5 is along the smooth placement web-like of internal face paper 7, when galloping, high velocity air rapidly from the gap of weld by the side of U-shaped fork 4 enter after the central siphon 5 of high speed rotating, it is directly subject to obstruct and the absorption of web-like paper 7, and directly friction occurs and impact with web-like paper 7, because web-like paper 7 is soft, thereby no matter how the friction of high velocity air and 7 generations of web-like paper and impact have fierceness, the noise producing can be by softening, be weakened, thereby noise is very little.So very little noise just can the hearing of disturbing influence navigating mate to other sound, and then just can not affect navigating mate to automobile normal driving yet, thereby guarantee automobile normal running.
Described web-like paper 7 thickness are 2.5mm soil 0.20mm.This makes web-like paper 7 can bear preferably the impact of high velocity air.
Described web-like paper 7 transverse tensile strength are not less than 37kN/m.This also makes web-like paper 7 can bear preferably the impact of high velocity air.
Described web-like paper 7 cross direction elongations are not less than 5.5%.This also makes web-like paper 7 can bear preferably the impact of high velocity air.
Described web-like paper 7 ash contents are not more than 2.0%.This also makes web-like paper 7 can bear preferably the impact of high velocity air.
The thickness of described web-like paper 7 and surperficial villus length uniformity.This makes web-like paper 7 bear more equably the impact of high velocity air and better reduce born impulsive force.
The surface of described web-like paper 7 does not have pleat, crackle, bulge.This also makes web-like paper 7 can bear more equably the impact of high velocity air and be not easy to be damaged.
