As a further improvement on the present invention, the described supporting inner core centre of gyration runs through and is provided with a central shaft, central shaftThe top centre of gyration is provided with one section of screw-threaded counterbore.
As a further improvement on the present invention, in described supporting, core inner sulfuration is provided with the anti-dumping of vertically arrangingCover pipe, and described overturn-preventing pipe and rhombus ironware are welded to connect.
As a further improvement on the present invention, described supporting inner core bottom is provided with cannelure.
As a further improvement on the present invention, on the damping fin of described upper strata, there is upwards bending outward extending flange knotStructure, leaves gap between this turnup structure outer rim and silicone oil chamber.
As a further improvement on the present invention, described lower floor damping fin bends downwards.
As a further improvement on the present invention, described rhombus ironware is respectively equipped with for connecting engineering at two ends along its lengthThe connecting hole of machinery base plate. Supporting inner core in product of the present invention adopts natural rubber to be made.
Technique effect of the present invention is: 1. this New Damping silicon oil shock absorber is installed between driver's cabin and chassis, adoptsUse high-quality natural rubber, utilize the good hysteretic characteristic of natural rubber, alleviate the impact of ground vibration on top driver's cabin;
2. this New Damping silicon oil shock absorber is added with Novel high-damping silicone oil in the Wan Shi mechanism of bottom, this silicon oil viscosityCharacteristic is very large, and larger damping force can be provided, and viscosity with temperature impact is little, can not reduce viscosity because Long-term Vibration heats up, withTime this high damping silicone oil effectively transmission of insulating noise to driver's cabin, increase cab comfort;
3. the guiding damping fin that this New Damping silicone oil damping is installed in silicone oil is designed to taper, and this design can be evenSilicone oil is divided in the chamber in two equal spaces, simultaneously have a circle damping hole first-class point of guiding damping fin, shake when havingWhen moving, silicone oil produces porous effect through damping hole, and larger damping force can be provided, and damping force equivalence, can not produce upwards and shakeMoving and the downward inconsistent situation of vibration damping power;
4. this New Damping silicone oil damping increase has Overthrow preventing device, can avoid driver's cabin in the situation of large load vibrationThe danger of toppling.
This New Damping silicone oil shock-damping structure is simple and reliable, and natural rubber integrated vulcanizing is easy for installation, safeguard simply,Long service life.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
In Fig. 1 ~ 3, comprise upper cover plate 1, supporting inner core 2, guiding damping fin 3, upper strata damping fin 3-1, the damping fin 3-of lower floor2, turnup structure 3-3, silicone oil chamber 4, damping silicone oil 5, damping hole 6, rhombus ironware 7, overturn-preventing pipe 8, central shaft 9, screw-threaded counterbore10, cannelure 11 etc.
As shown in Fig. 1 ~ 3, the present invention is a kind of damping silicon oil shock absorber, comprises the silicone oil chamber 4, close that damping silicone oil 5 is housedSupporting inner core 2, sulfuration that envelope is arranged on silicone oil chamber 4 are connected in the rhombus ironware 7 on supporting inner core 2 peripheries; Described supportingInner core 2 tops are fixedly connected with upper cover plate 1, and bottom is connected with guiding damping fin 3, and described guiding damping fin 3 comprises upper strata dampingSheet 3-1, the damping fin 3-2 of lower floor, its at the middle and upper levels damping fin 3-1 upper surface be close to supporting inner core 2 bottoms, the damping fin 3-2 of lower floorOn offer damping hole 6.
Described supporting inner core 2 centres of gyration run through and are provided with a central shaft 9, and the central shaft 9 top centres of gyration are provided with one sectionScrew-threaded counterbore 10.
The inner sulfuration of described supporting inner core 2 is provided with the overturn-preventing pipe 8 of vertically arranging, and described overturn-preventing pipe 8Be welded to connect with rhombus ironware 7, overturn-preventing pipe 8 is generally metalwork.
Described supporting inner core 2 bottoms are provided with cannelure 11, between this cannelure 11 and upper strata damping fin 3-1, form oil storageChamber, in the time of product work of the present invention, the silicone oil in silicone oil chamber 4, in the time being extruded on the damping fin 3-1 of upper strata, can be temporary in thisIn shoe cream room.
On described upper strata damping fin 3-1, there is upwards bending outward extending turnup structure 3-3, this turnup structure 3-3Between outer rim and silicone oil chamber 4, leave gap, so that the silicone oil in silicone oil chamber 4 can upwards overflow from gap, thereby playThe effect of damping shock absorption.
The described damping fin 3-2 of lower floor bends downwards, so that increase lifting surface area, plays better the effect of damping shock absorptionReally.
Described rhombus ironware 7 along its length two ends is respectively equipped with the connecting hole for connecting engineering machinery base plate.
The course of work of the present invention is as follows: in the time that body has vibration, supporting inner core 2 will produce vibration, in supportingCore 2 is made up of elastomeric material, so supporting inner core 2 can be produced elastic force and played by compression the object of damped vibration, togetherShi Zhendong can be passed on guiding damping fin 3, and guiding damping fin 3 just produces downward displacement with vibration in damping silicone oil 5, positionWhen moving, silicone oil will produce porous effect through damping hole 6, and damping force is provided, and damping force equivalence, and kinetic energy is converted toHeat energy, consumes vibrational energy and reaches isolating affection.
Overturn-preventing pipe 8 in product of the present invention is vertically arranged in the supporting inner core 2 that vulcanized rubber material makes, and and water chestnutShape ironware 7 is welded as a whole, and has limited the upwards large displacement of guiding damping fin 3 in the situation that of large load vibration, avoids drivingSail the danger of toppling of chamber.
