Abstract
The utility model relates to a torsional shock absorber. According to the technical scheme, the torsional shock absorber comprises an inner casing pipe which is connected with a torsion bar of a crank shaft, and an outer casing pipe which is used for transferring and inputting power into the crank shaft; the torsional shock absorber is characterized in that a rubber sleeve is fixed between the outer casing pipe and the inner casing pipe. In the torsional shock absorber, the rubber sleeve is arranged between the inner casing pipe and the outer casing pipe; and the torsional shock absorber acquires high intensity and durability by using elasticity of the rubber sleeve and the rigidity of metal. The vibration of parts of equipment, which are connected with the trosional shock absorber is released by damping force which is produced among the rubber sleeve, the outer casing pipe and the inner casing pipe, so the torsional shock absorber exerts the function of shock absorption and noise reduction.
Description
Technical field
The utility model relates to the parts that are used to alleviate vibrations on a kind of automobile, specifically is a kind of torsion vibration absorber.
Background technique
High speed development along with automobile industry; People have higher requirement to the power of motor, moment of torsion, volume etc.; The motor that body is less, the power moment of torsion is big more and more receives user's welcome and favor, so supercharging, direct fuel-injection engine become the direction and the trend of present engine research, the thing followed in succession; The explosive force that motor produced in when work is also increasing, engine operational speed improve constantly vibrations and the also corresponding aggravation of noise that is produced when making the bent axle operation.This just also has higher requirement to damping, the anti-acoustic capability of motor, how to solve the torsional shaking that bent axle produces in the engine operation process well, and the shockproof properties that improves motor also more and more receives people's attention.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the existing technology; A kind of torsion vibration absorber that is used to reduce the crankshaft torsion vibrations is provided; It is through damping force that rubber sleeve and outer sleeve and inner sleeve produced; Alleviate the vibrations of torsion vibration absorber institute connection device parts, played the effect of damping noise reduction.
According to the technological scheme that the utility model provides, torsion vibration absorber comprises it is characterized in that inner sleeve that is used for being connected with the bent axle torsion bar and the outer sleeve that is used for to bent axle transmission input power: combine to be fixed with rubber sleeve between said outer sleeve and the inner sleeve.
Further improvement as the utility model; Said outer sleeve length is less than inner sleeve length; Rubber sleeve length is less than outer sleeve length; Rubber sleeve inner edge two ends extend axially and combine fully to fix with the inner sleeve outer wall, and rubber sleeve outer rim two ends extend axially and combine fully to fix with outer sleeve inner wall; Be arc-shaped transition between rubber sleeve inner edge extension part and outer rim extension part and the rubber sleeve end face.
As the further improvement of the utility model, the outer periphery at said inner sleeve two ends also coats the bound rubber cover along the chamfering inclined-plane that is provided with 45 ° on this chamfering inclined-plane.
As the further improvement of the utility model, the outer periphery at said outer sleeve two ends is along the chamfering inclined-plane that is provided with 30 °.
As the further improvement of the utility model, said rubber sleeve adopts bonding mode to combine to fix with outer sleeve, inner sleeve.
The utility model compared with prior art, advantage is: the utility model utilizes the elasticity of rubber sleeve and the rigidity of metal through between sleeve pipe and the inner sleeve rubber sleeve being set outside, makes that turn round the shake vibration damper obtains higher intensity and durability.Through the damping force that rubber sleeve and outer sleeve and inner sleeve produced, alleviate the vibrations of torsion vibration absorber institute connection device parts, played the effect of damping noise reduction.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1, the torsion vibration absorber of the utility model mainly is made up of inner sleeve 1, outer sleeve 3 and rubber sleeve 2, and said inner sleeve 1 is used for being connected with the bent axle torsion bar; Said outer sleeve 3 is used for to bent axle transmission input power; Said rubber sleeve 2 is arranged between outer sleeve 3 and the inner sleeve 1 and combines closely fixingly with bonding mode with them, and rubber sleeve 2 is used to alleviate the vibrations of outer sleeve 3 and 1 connection device parts of inner sleeve.
As shown in Figure 1; Among the utility model embodiment; Said outer sleeve 3 length are less than inner sleeve 1 length; Rubber sleeve 2 length are less than outer sleeve 3 length, and rubber sleeve 2 inner edge two ends extend axially and combine fully to fix with inner sleeve 1 outer wall, and rubber sleeve 2 outer rim two ends extend axially and combine fully to fix with outer sleeve 3 inwalls; Between rubber sleeve 2 inner edge extension part 2a and outer rim extension part 2b and rubber sleeve 2 end faces is arc-shaped transition.Can make between rubber sleeve 2 and inner sleeve 1, the outer sleeve 3 like this has high adhesive strength, improves in its working life.
As shown in Figure 1, the outer periphery at said inner sleeve 1 two ends also coats bound rubber cover 2 along the chamfering inclined-plane that is provided with 45 ° on this chamfering inclined-plane.Increased the bonded area of rubber sleeve 2 like this, improved adhesive strength with inner sleeve 1.
As shown in Figure 1, the outer periphery at said outer sleeve 3 two ends is along the chamfering inclined-plane that is provided with 30 °.
The utility model utilizes the elasticity of rubber sleeve 2 and the rigidity of metal, makes that turning round the shake vibration damper obtains higher intensity and durability.Through rubber sleeve 2 and the damping force that outer sleeve 3 and inner sleeve 1 are produced, alleviate the vibrations of torsion vibration absorber institute connection device parts, played the effect of damping noise reduction.
