Abstract
The utility model belongs to the technical filed of transmission shafts, and particularly relates to a vibration-proof transmission shaft, which includes a shaft pipe, wherein a damping paper or a sponge is arranged in the shaft pipe. By adopting the vibration-proof transmission shaft, vibration is greatly reduced during the using process of the transmission shaft, so as to avoid a chassis from vibration and prevent the transmission shaft from being broken off, and the vibration-proof transmission shaft has extremely remarkable vibration-proof effect.
Description
Technical field
The utility model belongs to the transmission shaft technical field, is specifically related to a kind of vibration proof transmission shaft.
Background technique
The original automobilism velocity ratio of China is lower; 50-65 kilometers/hour of average speed per hours; Along with China's expressway is fast-developing, automobilism speed generally improves, 80-120 kilometers/hour of average speed per hours; Require the truck drive shaft rotating speed also increasingly high, originally to show unconspicuous automobile chassis vibration problem more and more outstanding for low speed driving.Transmission shaft in use is in the high speed rotating state, vibrates easily, and its reason mainly contains following two aspects:
1, transmission shaft is used for transmitting the moment of torsion between speed changer and the ransaxle, because the usage requirement of itself, vibration source amplitude when transmission shaft of automobile axle, speed changer, engine producing will be amplified cause the automobile chassis vibration.
2, the transmission shaft of high speed rotating is the perturbed force that draws the transmission shaft flexure vibrations because of the inertial force that its mass eccentricity (the transmission shaft wall unevenness is even, and foozle, assembly error etc. cause barycenter not overlap with the rotating shaft center) produces.When the frequency of this perturbed force equals the natural frequency of flexure vibrations of transmission shaft, just resonate, cause amplitude sharply to increase, the danger that transmission shaft is fractureed is arranged.
The structure of traditional transmission shaft is as shown in Figure 1, comprises central siphon 1, and the measure of central siphon 1 aspect vibration damping is less.
The model utility content
The utility model provides a kind of transmission shaft of vibrating of effectively preventing.
The utility model adopts following technological scheme:
The vibration proof transmission shaft comprises central siphon, is provided with damping paper or sponge in the central siphon.
When damping paper was set in the central siphon, damping paper was arranged on the inwall along the shaft tube inner wall circumferencial direction.
When in the central siphon sponge being set, sponge is filled with in the pipe of central siphon.
The utility model is provided with damping paper or sponge in the central siphon of transmission shaft, changed the natural frequency of transmission shaft, makes the natural frequency of transmission shaft avoid the frequency of okperation section, can stablize driving torque in the efficient working range, has reduced the vibration of transmission shaft to a great extent; Damping paper that is provided with in the central siphon simultaneously or sponge be absorbed oscillation effectively, and its vibration attenuation mechanism is to lean on consumed energy to reduce amplitude to come vibration damping, is delivered to the vibration at transmission shaft place with the vibration source of eliminating automobile axle, speed changer, engine producing.The utility model makes transmission shaft vibration in use significantly reduce, thereby avoids the chassis vibration, prevents that transmission shaft from fractureing, and effect is fairly obvious,
Description of drawings
Fig. 1 is the structural representation of traditional transmission shaft;
Fig. 2 is the structural representation of the utility model embodiment 1 transmission shaft;
Fig. 3 is the structural representation of the utility model embodiment 2 transmission shafts.
Embodiment
Transmission shaft as shown in Figure 2 comprises central siphon 1, and the inwall of central siphon 1 is provided with along the inwall damping paper 2 in one week.
During transmission shaft work, damping paper 2 is absorbed oscillation effectively, is delivered to the vibration at transmission shaft place with the vibration source of eliminating automobile axle, speed changer, engine producing.The natural frequency that has changed transmission shaft behind the damping paper 2 is set in the central siphon 1 of transmission shaft, makes the natural frequency of transmission shaft avoid the frequency of okperation section, can stablize driving torque in the efficient working range, reduced the vibration of transmission shaft to a great extent.
Embodiment 2
Transmission shaft as shown in Figure 3 comprises central siphon 1, has been filled with sponge 3 in the pipe of central siphon 1.
During transmission shaft work, sponge 3 is absorbed oscillation effectively, is delivered to the vibration at transmission shaft place with the vibration source of eliminating automobile axle, speed changer, engine producing.The natural frequency that has changed transmission shaft behind the sponge 3 is set in the central siphon 1 of transmission shaft, makes the natural frequency of transmission shaft avoid the frequency of okperation section, can stablize driving torque in the efficient working range, reduced the vibration of transmission shaft to a great extent.
