In order to achieve the above object, the technical solution of the utility model is: the spring top tray of a kind of amortisseur, and including top tray seat, its innovative point is in that: described top tray seat is the plastic part of integrated injection molding；Described top tray seat has outer shroud, axis hole and internal ring, internal ring is coaxial with axis hole, and internal ring is coaxial with outer shroud, and chamber installed by the spring forming annular between outer wall and the inwall of outer shroud of described internal ring, the bottom of described outer shroud has flange, and the periphery of flange has annular boss.

In technique scheme, the internal diameter of described annular boss is more than the external diameter of outer shroud, and the counterbore bottom surface of annular boss has the first reinforcement of ring stiffener and several radial directions being evenly arranged along its circumferencial direction, the end face deviating from annular boss side of described flange has several second reinforcements and the outer wall of the second reinforcement and outer shroud one each other.

In technique scheme, the bottom surface of chamber installed by the spring of described top tray seat is helicoid, and helicoid is provided with the retaining wall that spring end can rise barrier effect.

In technique scheme, several second reinforcements described there is a trapezoidal shape, all the other equal triangular shape, and the second reinforcement of trapezoidal shape is positioned at the close retaining wall place on outer shroud outer wall.

In technique scheme, the material of described top tray seat is nylon and glass fibre.

In technique scheme, the ring wall of described outer shroud has gap, the second reinforcement place of the close trapezoidal shape that described gap is positioned on outer shroud.

This utility model is had the advantages that: after adopting the spring top tray of amortisseur of the present utility model, including top tray seat, owing to described top tray seat is the plastic part of integrated injection molding；Described top tray seat has outer shroud, axis hole and internal ring, and internal ring is coaxial with axis hole, and internal ring is coaxial with outer shroud, chamber installed by the spring forming annular between outer wall and the inwall of outer shroud of described internal ring, the bottom of described outer shroud has flange, and the periphery of flange has annular boss, so, this utility model is lightweight not only, alleviate load, reduce energy consumption so that it is energy-conserving and environment-protective, and the good corrosion resistance of the top tray seat of plastic part, not easily get rusty.

Detailed description of the invention

Below in conjunction with accompanying drawing and the embodiment that provides, this utility model is further described, but is not limited thereto.

As shown in Fig. 1,2,3,4,5, the spring top tray of a kind of amortisseur, including top tray seat 1, described top tray seat 1 is the plastic part of integrated injection molding；

Described top tray seat 1 has outer shroud 1-1, axis hole 1-2 and internal ring 1-3, internal ring 1-3 is coaxial with axis hole 1-2, and internal ring 1-3 is coaxial with outer shroud 1-1, chamber 1-4 installed by the spring forming annular between outer wall and the inwall of outer shroud 1-1 of described internal ring 1-3, the bottom of described outer shroud 1-1 has flange 1-9, and the periphery of flange 1-9 has annular boss 1-5.

As shown in Fig. 2,4,5, in order to improve plastic strength of the present utility model further, the internal diameter of the described annular boss 1-5 external diameter more than outer shroud 1-1, and the counterbore 1-10 bottom surface of annular boss 1-5 has the first reinforcement 1-6 of ring stiffener 1-11 and several radial directions being evenly arranged along its circumferencial direction, the end face deviating from annular boss 1-5 side of described flange 1-9 has several second reinforcements 1-7 and the outer wall of the second reinforcement 1-7 and outer shroud 1-1 one each other.

As shown in Figure 4, for the ease of equipped, and the end of spring one end being played the effect of keeping out, the bottom surface of chamber 1-4 installed by the spring of described top tray seat 1 is helicoid, and helicoid is provided with the retaining wall 1-8 that spring end can rise barrier effect.

As shown in Fig. 1,3,4,5, so that this utility model structure is more reasonable, and guarantee that plastic strength is high, described several second reinforcements 1-7 there is a trapezoidal shape, all the other equal triangular shape, and the second reinforcement 1-7 of trapezoidal shape is positioned at the close retaining wall 1-8 place on outer shroud 1-1 outer wall.

So that intensity of the present utility model and fatigue durability are good, the material of top tray seat 1 described in the utility model is nylon and glass fibre.

As shown in Figure 4, for the ease of the spring pad positioning assembling with amortisseur, the ring wall of described outer shroud 1-1 has gap 1-1-1, the second reinforcement 1-7 place of the close trapezoidal shape that described gap 1-1-1 is positioned on outer shroud 1-1.

This utility model is after tested:

1) strength test:

Testing under room temperature: at room temperature 23 DEG C, product does not still have the failure phenomenons such as cracking or fracture under the load of carrying 30KN；

Testing under low temperature: after part is placed 24 hours at the low temperature environment temperature of-30 DEG C, product does not still have the failure phenomenons such as cracking or fracture under the load of carrying 30KN；

Testing under high temperature: after part is placed 24 hours under the high ambient temperatures of 120 DEG C, product does not still have the failure phenomenons such as cracking or fracture under the load of carrying 30KN.

2) fatigue test test:

Fatigue test test under room temperature: at room temperature 23 DEG C, product, by the frequency with 4Hz, is applied in 2 ~ 14KN sinusoidal wave load, after 200,000 circulations, product does not still have the failure phenomenons such as cracking or fracture.

During this utility model assembling, spring installation cavity of the present utility model indoor will be arranged on the top of the spring of amortisseur, and make one end of spring and retaining wall 1-8 offset, this utility model is not only convenient for assembling with spring, and this utility model not only lightweight, alleviates load, reduce energy consumption, make its energy-conserving and environment-protective, and the good corrosion resistance of the top tray seat of plastic part, not easily get rusty.
