Abstract
The invention discloses an automobile noise reduction transmission shaft. The automobile noise reduction transmission shaft comprises a shaft pipe, a cardan joint and an installing flange, wherein the cardan joint and the installing flange are located at the two ends of the shaft pipe respectively. The automobile noise reduction transmission shaft is characterized in that the inner wall of the shaft pipe is provided with a rubber coating, and the rubber coating is closely attached to the inner wall of the shaft pipe. The automobile noise reduction transmission shaft has the advantages that the rubber coating is added, and the wall thickness of the rubber coating and the wall thickness of the metal shaft pipe are reasonably designed. When the transmission shaft rotates, the vibration of the transmission shaft can be rapidly transmitted to rubber damping materials closely coated on the metal shaft pipe, the corresponding dislocation of the interior of the rubber materials and shearing deformation of friction materials can be caused, and due to the fact that part of mechanical energy is converted into thermal energy through internal friction of the rubber damping materials, the purposes of reducing vibration and noise are achieved.
Description
Technical field
The present invention relates to auto parts machinery field, particularly a kind of automobile noise reduction transmission shaft of noise reduction.
Background technique
In vehicle structure, generally connect speed changer and ransaxle with transmission shaft.In actual vehicle uses, this transmission shaft needs reliably and stably transfer motion power, and using the resonance phenomenon that do not have in vehicle speed range, and noise while effectively reducing transmission shaft operation.At present, the metal central siphon of traditional truck drive shaft is rolled and is formed by low carbon steel plate, and inside is cavity structure.In the time of galloping, the rotating speed of transmission shaft is general identical with engine speed, and maximum speed can exceed 5000r/min, and the vibration and the noise that cause thus bring very uncomfortable sensation to occupant.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of truck drive shaft that can vibration and noise reducing.
In order to realize above-mentioned target, the present invention adopts following technological scheme:
Automobile noise reduction transmission shaft, comprises central siphon, lays respectively at universal joint and the mounting flange at central siphon two ends, it is characterized in that, described shaft tube inner wall is provided with rubber coating, and the inwall of described rubber coating and central siphon fits tightly; The thickness of described rubber coating is the more than 2 times of wall thickness of described central siphon; Described rubber coating and central siphon sulfuration or bonding connection.
Aforesaid automobile noise reduction transmission shaft, is characterized in that, described central siphon is aluminum alloy central siphon or carbon fiber central siphon.
Aforesaid automobile noise reduction transmission shaft, is characterized in that, described rubber coating inwall is provided with protective layer, between described rubber coating and protective layer, is provided with vacuum layer.
Aforesaid automobile noise reduction transmission shaft, is characterized in that, the thickness of described vacuum layer is less than the thickness of described rubber coating, and the thickness of described protective layer is less than the thickness of described vacuum layer.Further, the thickness of described vacuum layer is less than the wall thickness of described tubular axis.
Aforesaid automobile noise reduction transmission shaft, is characterized in that, described protective layer is carbon fiber layer.
Usefulness of the present invention is: automobile noise reduction transmission shaft of the present invention has increased rubber coating, and the wall thickness dimension of appropriate design rubber coating and metal central siphon.In the time that transmission shaft rotates, its vibrational energy passes to rapidly tight painting and is attached to the rubber damping material on metal central siphon, cause that the inner corresponding changing of the relative positions of rubber material and friction material produce shear deformation, change part mechanical energy into heat energy due to the interior friction of rubber damping material, thereby reach the object of vibration and noise reducing.
Brief description of the drawings
Fig. 1 is structural representation of the present invention
Fig. 2 is the enlarged view at A place in Fig. 1.
The implication of reference character in figure:
1-central siphon, 11-rubber coating, 12-protective layer, 13-vacuum layer, 2-universal joint, 3-mounting flange.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
Automobile noise reduction transmission shaft as shown in Figure 1, comprise central siphon 1, universal joint 2, mounting flange 3, universal joint 2 and mounting flange 3 lay respectively at the two ends of central siphon 1, central siphon 1 inwall is provided with rubber coating 11, rubber coating 11 fits tightly with central siphon 1 inwall, and the thickness of rubber coating 11 is the more than 2 times of wall thickness of central siphon 10.
Together with rubber coating 11 is fitted tightly with central siphon 10, rubber coating 11 can be connected by sulfuration with central siphon 10, and rubber coating 11 also can be connected by bonding with central siphon 10.For the effect that reaches vibration and noise reducing is not wasted again rubber material, the thickness of preferred rubber coating 11 is 2 times of wall thickness of central siphon 10.
As a kind of preferred version, central siphon 10 is aluminum alloy central siphon, and aluminium alloy quality is light, easily mass balance, the radial vibration that can effectively lower transmission shaft.As another kind of preferred version, central siphon 10 also can be selected carbon fiber central siphon, and the light toughness of carbon fiber central siphon quality greatly also can effectively lower the radial vibration of transmission shaft, and has advantages of anti-corrosion and high strength, has increased the life-span of transmission shaft.
In order to increase the life-span of rubber coating 11, rubber coating 11 inwalls are provided with protective layer 12, between rubber coating 11 and protective layer 12, are provided with vacuum layer 13, and vacuum-energy plays the effect of noise reduction.The thickness of vacuum layer 13 is less than the thickness of rubber coating 11, and preferably, the thickness of vacuum layer 13 is less than the wall thickness of tubular axis 1, and the thickness of vacuum layer 13 is unsuitable excessive, convenient like this processing.Meanwhile, the thickness of vacuum layer 13 is unsuitable too small, and bad like this processing cannot play a role again, and therefore the thickness of vacuum layer 13 is greater than the thickness of protective layer 12, and the thickness of protective layer 12 is less than the thickness of vacuum layer 13, preferably 1 ~ 2mm of the thickness of protective layer 12.The preferred carbon fiber layer of protective layer 12, the light intensity of carbon fiber quality is large, and rubber coating 11 and vacuum layer 13 can adequately protect.
More than show and described basic principle of the present invention, major character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technological scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
