Problems solved by technology

But the structure is complicated, the cost is high, and the maintenance cost is also high
[0007] For a long time, people only considered how to reduce external impact and eliminate vibration and noise, but did not consider how to reduce internal vibration and noise
Thereby the traditional shock absorber can only effectively reduce the positive vibration, but can not produce any effect on the vibration source of the engine itself, and the effect of reducing the torsional vibration is also very poor; the damping effect of the existing rubber shock absorber cannot be obtained. Further improve

Embodiment 1

[0025] As shown in the figure, an engine suspension shock absorber is produced, which includes an outer tube 1, an inner tube 2 and a rubber layer 3 bonded between the outer tube and the inner tube, and is characterized in that the outer tube 1 is made of a magnesium alloy material Production; the thickness of the outer tube wall is greater than the thickness of the rubber layer; the present embodiment makes the volume ratio of the magnesium alloy outer tube 1, rubber layer 3 and inner tube 2 into 8:1:1; rubber layer 3 and The inner tube 2 is made of conventional materials, so that the magnesium alloy outer tube 1 can be used as the main shock absorbing force to effectively eliminate vibration and noise.

Embodiment 2

[0027] As shown in the figure, the bonding contact surface between the rubber layer 3 in the engine suspension shock absorber and the inner wall of the magnesium alloy outer tube 1 is made into a wave-shaped contact surface 4, and the side surface of the rubber layer is made into an inwardly concave arc Surface shape side outer surface 5. In this way, the rubber layer 3 can effectively transmit the vibration to the magnesium alloy outer tube 1 through the wave-shaped contact surface 4 when it receives a vibration shock, and the deformation space of the rubber layer 3 when it is deformed by the impact can be formed from the curved surface shape of the inward depression to the outside. The surface 5 is deformed outward so as to absorb the shock-absorbing bulging space required for deformation without making the rubber layer 3 protrude outward.

Embodiment 3

[0029] A shock-absorbing magnesium alloy material is produced, and its chemical composition is composed of main elements, auxiliary elements and impurity elements, wherein the main element is magnesium, the auxiliary elements are aluminum, manganese, zinc, and the impurity elements are iron, nickel, copper, and calcium.

[0030] The percentage content of each chemical composition of the magnesium alloy material in the total amount of the magnesium alloy material is: auxiliary elements AL6%, Mn0.45%, Zn0.45%, impurity elements Fe≤0.005%, Ni≤0.009%, Cu ≤0.025%, Ca≤0.08%, and the balance is Mg.

[0031] The preparation process of the magnesium alloy material is as follows.

[0032] (1) Completely melt the main element material magnesium ingot to obtain magnesium liquid.

[0033] (2) Preheat aluminum ingots, manganese ingots and zinc ingots as auxiliary element materials to 120°C, then add them into completely melted magnesium liquid, melt all materials, then stir evenly, remove ...

Abstract

An engine suspension shock absorber comprises an outer tube, an inner tube and a rubber layer. The outer tube is made of a magnesium alloy material, the thickness of the tube wall of the outer tube is larger than that of the rubber layer, and the magnesium alloy material is composed of a main element of magnesium, auxiliary elements of aluminum, manganese and zinc and impurity elements of iron, nickel, copper and calcium. The engine suspension shock absorber has the advantages that the magnesium alloy outer tube is adopted as the main material for shock reduction, and meanwhile shock absorption, shock reduction and noise reduction can be effectively achieved by adjusting the size ratio of the outer tube, the rubber layer and the inner tube; the magnesium alloy material absorbs the impurity elements after adopting the auxiliary elements, irregular microscopic defects can be generated in microcrystals in magnesium alloy, shock and noise which are generated by an engine itself can be dissipated by converting a large amount of energy into thermal energy in the process of passing through the magnesium alloy material, and therefore the function of reducing the shock and noise is achieved; the engine suspension shock absorber has an especially obvious shock reduction effect, and particularly the persistent problem that a traditional rubber vibration absorption structure cannot eliminate self-vibration of a vibration source of the engine and transverse violent swing vibration caused by abrupt acceleration of the engine is effectively solved.

Description

technical field [0001] The invention relates to the technical field of automobile engine suspension equipment, in particular to an engine suspension shock absorber. Background technique [0002] With the continuous development of society, people's requirements for cars are getting higher and higher. Including the performance requirements of the car's power, economy, braking, handling stability, ride comfort, and passability. The shock absorber is a damping system installed between the car body and the road wheel. Its function is to attenuate the vibration of the car body and prevent the infinite increase of the car body amplitude under the condition of resonance, which can reduce the amplitude and vibration frequency of the car body vibration. , At the same time, it can also reduce noise, so it can prolong the fatigue life of elastic components and improve the comfort of people riding. [0003] Shock absorbers are installed in the suspension of most cars. At present, the m...
