Abstract
The invention discloses a kind of automobile noise reduction transmission shaft, comprise central siphon, lay respectively at universal joint and the mounting flange at central siphon two ends, and 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.Usefulness of the present invention is: automobile noise reduction transmission shaft of the present invention adds rubber coating, and the wall thickness dimension of appropriate design rubber coating and metal central siphon.When drive axis, its vibrational energy passes to rapidly the rubber damping material being closely coated with and being attached on metal central siphon, the inner corresponding changing of the relative positions of rubber material and friction material is caused to produce shear deformation, some mechanical can be changed into heat energy due to friction in rubber damping material, thus reach the object of vibration and noise reducing.
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, the general transmission shaft that uses connects speed changer and ransaxle.In the vehicle of reality uses, this transmission shaft needs reliably and stably transfer motion power, and the resonance phenomenon that do not have in use vehicle speed range, and effectively reduce noise when transmission shaft runs.At present, the metal central siphon of traditional truck drive shaft is rolled by low carbon steel plate and forms, and inside is cavity structure.When galloping, the rotating speed of transmission shaft is general identical with engine speed, and maximum speed can more than 5000r/min, and the vibration & noise caused thus brings 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 can the truck drive shaft of vibration and noise reducing.
In order to realize above-mentioned target, the present invention adopts following technological scheme:
Automobile noise reduction transmission shaft, comprise central siphon, lay 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 more than 2 times of the 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, is provided with vacuum layer between described rubber coating and protective 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 central siphon.
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 adds rubber coating, and the wall thickness dimension of appropriate design rubber coating and metal central siphon.When drive axis, its vibrational energy passes to rapidly the rubber damping material being closely coated with and being attached on metal central siphon, the inner corresponding changing of the relative positions of rubber material and friction material is caused to produce shear deformation, some mechanical can be changed into heat energy due to friction in rubber damping material, thus reach the object of vibration and noise reducing.
Accompanying drawing explanation
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, concrete introduction is done to the present invention.
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 and central siphon 1 inwall fit tightly, and the thickness of rubber coating 11 is more than 2 times of the wall thickness of central siphon 10.
Together with being fitted tightly with central siphon 10 by rubber coating 11, rubber coating 11 can be connected by sulfuration with central siphon 10, and rubber coating 11 and central siphon 10 also can by bonding connections.In order to the effect reaching vibration and noise reducing does not waste rubber material again, the thickness of preferred rubber coating 11 is 2 times of the 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, and easy mass balance, effectively can lower the radial vibration of transmission shaft.As another kind of preferred version, central siphon 10 also can select carbon fiber central siphon, and the light toughness of carbon fiber central siphon quality greatly also effectively can lower the radial vibration of transmission shaft, and has the advantage of anti-corrosion and high strength, adds the life-span of transmission shaft.
In order to increase the life-span of rubber coating 11, rubber coating 11 inwall is provided with protective layer 12, is provided with vacuum layer 13 between rubber coating 11 and protective layer 12, 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 central siphon 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 namely the thickness of protective layer 12 is less than the thickness of vacuum layer 13, the thickness preferably 1 ~ 2mm of protective layer 12.Protective layer 12 is carbon fiber layer preferably, and the light intensity of carbon fiber quality is large, and can adequately protect rubber coating 11 and vacuum layer 13.
More than show and describe 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, the technological scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
