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 made, 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 magnesium alloy material The thickness of the outer tube wall is greater than the thickness of the rubber layer; in this embodiment, the volume ratio of the magnesium alloy outer tube 1, the rubber layer 3, and the inner tube 2 is 8:1:1; the 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 absorption force, effectively eliminating vibration and noise.

Embodiment 2

[0027] As shown in the figure, the adhesive 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 面形面面外面5 In this way, when the rubber layer 3 receives a shock impact, the vibration can be effectively transmitted to the magnesium alloy outer tube 1 through the wave-shaped contact surface 4, and the deformation space of the rubber layer 3 when it is deformed by the impact can be depressed from the arc-shaped side surface. The surface 5 deforms outwards, so as to digest the shock-absorbing bulging space required for deformation without causing the rubber layer 3 to 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. The main element is magnesium, the auxiliary elements are aluminum, manganese, and zinc, and the impurity elements are iron, nickel, copper, and calcium.

[0030] The percentage content of each chemical component mass of the magnesium alloy material in the total 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%, 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] ⑵Preheat aluminum ingots, manganese ingots and zinc ingots of auxiliary element materials to 120℃, and then add them to the completely molten magnesium liquid, melt all the materials, and stir evenly to remove surface scum to obtai...

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 have higher and higher requirements for cars. Including the performance requirements of automobile power, economy, braking, handling stability, ride comfort, and passing performance. The shock absorber is a damping system installed between the car body and the road wheels. Its function is to attenuate the vibration of the car body and prevent the amplitude of the car body from increasing indefinitely in the case of resonance. It can reduce the amplitude and number of vibrations of the car body. At the same time, it can also reduce noise, thereby prolonging the fatigue life of the elastic element and improving the comfort of passengers. [0003] Most cars are equipped with shock absorbers in their suspensions. At present, the most widely u...
