Description
Technical field
The utility model relates to a kind of shock absorbing apparatus, and especially the forward and backward shock absorber of putting of motorcycle, electric bicycle, mountain bike use also can be used as automobile engine cover fulcrum or back chamber door fulcrum.
Background technique
At present, shock absorber on the motorcycle of knowing, electric bicycle, the mountain bike and automobile engine cover fulcrum, back chamber door fulcrum mainly are divided into three kinds of oil pressure type, air-pressure type (utilizing pressure that the density of oil, gas is reduced to reach flexible purpose) and spring types; When running into also powerful suddenly impulse force, the compressive force of oil pressure type, air-pressure type and spring type can reach capacity very soon, not only loses flexible, buffer function, also can cause damage; In addition, through using for a long time, oil pressure type, air-pressure type and three kinds of vibration dampers of spring type need refill built-in oil, gas or change spring, and in use, oil pressure type, air-pressure type and three kinds of shock absorbers of spring type can cause disappearing gradually of elasticity because of the loss of built-in oil, gas and spring.
The model utility content
The purpose of this utility model provides a kind of improvement of shock absorbing apparatus, and this device should be able to overcome the deficiency of above-mentioned background technology, the characteristics that have the shock-absorbing stable performance, can bear strong impact force, and simple in structure, easy to manufacture, with low cost.
The technical solution adopted in the utility model is: the permanent magnetism shock absorber, comprise that the exhausted magnetic shell body of tubular, some blocks of magnet steel that are arranged in a linear and Lower Half insert the thrust axis in the exhausted magnetic shell body in exhausted magnetic shell body, the lower end closed of described exhausted magnetic shell body, the upper end open of exhausted magnetic shell body connects a capping, and the centre of capping has axis hole; Described thrust axis lower end is provided with piston, the outer peripheral surface of piston and the inner peripheral surface fit that cuts off the magnetic shell body; Described some magnet steel all keep certain interval so that be in sliding mode with the inwall of exhausted magnetic shell body, and adjacent in twos magnet steel all is set to the same polarity face in opposite directions and right.
Described some blocks of magnet steel are divided into two groups, wherein are positioned at one group of magnet steel that comprises at least one annulus cylindricality of exhausted magnetic shell body upper end, and the piston of described thrust axis lower end relocated in exhausted magnetic shell body after passing through these annulus cylindricality magnet steel; All has the gap between the inner peripheral surface of annulus cylindricality magnet steel and exhausted magnetic shell body and the outer peripheral surface of thrust axis.
The upper end open of described exhausted magnetic shell body is to be threaded with capping.
Working principle of the present utility model is: the two ends of permanent magnetism shock absorber (being the upper end of thrust axis and the lower end of exhausted magnetic shell body) is connected respectively on the different objects by screw or axis hole; When the suffered external force of thrust axis was stablized, mutual expelling force between each magnetic steel ingot and suffered external force reached balance, did not have relative movement between thrust axis and the exhausted magnetic shell body; When external force increases, thrust axis is compressed with regard to the axial push magnet steel it is moved down, position between each magnetic steel ingot of its bottom since change thus each magnetic steel ingot between mutual expelling force increase immediately, formed combination mutual expelling force increases sharply, until flat permanent with the thrust of thrust axis; When thrust axis because of thrust during less than the combination mutual expelling force resilience of each magnetic steel ingot, the ring magnetic steel of the upper end of exhausted magnetic shell body is because the effect of homopolar-repulsion power reaches the buffering purpose.
The utility model is being owing to be provided with the powerful permanent magnetic steel ingot in exhausted magnetic shell body, the principle of utilizing the same polarity of magnet steel to repel each other reaches the purpose of flexible shock-absorbing.During as the shock absorbing apparatus on the motorcycle, electric bicycle, mountain bike, not only the shock-absorbing ability is strong, and simple in structure, be difficult for loss.
Description of drawings

Fig. 2 is a three-dimensional generalized section of the present utility model.
Embodiment
As shown in the figure, this permanent magnetism shock absorber comprises exhausted magnetic shell body 5, the some blocks of magnet steel that are arranged in a linear of tubular and inserts the thrust axis 1 that cuts off in the magnetic shell body in exhausted magnetic shell body; The lower end closed of described exhausted magnetic shell body, the upper end open of exhausted magnetic shell body connect a capping 4 (general, the upper end open of exhausted magnetic shell body adopts with capping and is threaded), and the centre of capping has perforate; The inner peripheral surface fit (keeping certain interval) of the piston 2-1 of described thrust axis lower end and exhausted magnetic shell body with the inwall of exhausted magnetic shell body, thereby after thrust axis inserts in the exhausted magnetic shell body by this perforate, and just can carry out axial relative movement between the exhausted magnetic shell body; And because piston 2-1 is subjected to the restriction of capping perforate, thrust axis is positioned in the exhausted magnetic shell body can only do axial relative movement and rotation.Described some magnet steel all keep certain interval so that be in sliding mode with the inwall that cuts off the magnetic shell body; And as can be seen from Figure 2: adjacent in twos magnet steel all is set to the same polarity face in opposite directions and to (as the N utmost point of the N utmost point of magnet steel 2-3 and magnet steel 2-4 in opposite directions and right, and the S utmost point of the S utmost point of magnet steel 2-3 and magnet steel 2-4 is in opposite directions and right, remaining magnet steel 2-1,2-2,2-5,2-6 also and the like setting).
For improving shock-proof effect, described some blocks of magnet steel are divided into two groups, wherein be positioned at one group of magnet steel that comprises at least one annulus cylindricality (cross section is a ring) of exhausted magnetic shell body upper end, these annulus cylindricality magnet steel all have the gap with the inner peripheral surface of exhausted magnetic shell body and the outer peripheral surface of thrust axis, thereby can keep endwisely slipping flexibly; The piston of described thrust axis lower end relocated in exhausted magnetic shell body after passing through these annulus cylindricality magnet steel.Show among Fig. 2 that piston 2-1 passed through two blocks of annulus cylindricality magnet steel (being magnet steel 3-1 and magnet steel 3-2); Nature, the quantity of annulus cylindricality magnet steel is the amount doesn't matter, decides as requested.
In sum, the utlity model has following three kinds of mode of executions:
Embodiment 1: do not have annulus cylindricality magnet steel, this moment, shock absorber only was used to bear pressure.
Embodiment 2: as shown in Figure 1 and Figure 2, annulus cylindricality magnet steel is less than other magnet steel, and the shock absorber of this moment mainly still is used to bear pressure.
Embodiment 3: annulus cylindricality magnet steel is more than other magnet steel, and the shock absorber of this moment can be used to bear pulling force.
Also be pointed out that; The length of the spacing between the quantity of magnet steel, each magnet steel, exhausted magnetic shell body etc. is also all decided according to designing requirement.In addition, exhausted magnetic shell body generally can adopt the clean steel manufacturing.
