Description
Technical field
This utility model relates to silicon oil damper, is specially a kind of two grades of silicon oil dampers.
Background technology
Vibroshock is different by its resisting medium adopted, and can be divided into the elastic big class of torsional vibration damper two of viscosity (silicone oil) torsional vibration damper and (rubber).Their basic structure is by housing or wheel hub, damping element (silicone oil or rubber) and has three kinds of parts of damping body of certain rotary inertia and forms.Its middle shell or wheel hub are connected with the engine crankshaft front end needing vibration damping.Engine crankshaft must produce torsional oscillation when running, and damping element makes the motion of generation and torsional oscillation opposite in phase between damping body and housing or wheel hub, thus reaching to offset or weaken the purpose of electromotor shafting torsional oscillation.
Silicon oil damper is a kind of conventional vibroshock, but currently used silicon oil damper only has one-level vibration damping, therefore to meet the vibration damping needs of bent axle, it is generally required to that the size of damping body is done is very big, but this size that will result directly in whole vibroshock undoubtedly increases, owing to the cooperation between each part of vehicle is extremely compact, the increase of vibroshock size will limit its use on vehicle greatly.
Utility model content
This utility model is intended to provide a kind of two grades of silicon oil dampers that can effectively reduce whole vibroshock size when meeting vibration damping demand.
nullTwo grades of silicon oil dampers in this programme，Including shell and side cover，Shell is connected with outside bent axle，Shell offers the first groove，Hydraulic chamber is formed between first groove and side cover，The first damping body and the second damping body it is provided with in hydraulic chamber，Between first damping body and the second damping body、Silicone oil all it is filled with between first damping body and hydraulic chamber and between the second damping body and hydraulic chamber，Side cover and the first damping body are connected by the first bolt，Second damping body offers the second screwed hole，Second screwed hole runs through the second damping body and communicates with hydraulic cavities，Second damping body and side cover are attached by being located at second bolt at the second screwed hole place，Second bolt is further opened with oil filler point，Oil filler point is through the second bolt and communicates with the second screwed hole，The head of the second bolt is additionally provided with cover plate，Cover plate and the second bolt are attached by plus screw.
The principle of this programme is: when bent axle twists vibration, shell will twist vibration with bent axle, the first damping body that now rotary inertia is bigger than shell will vibrate with the speed less than shell, then relative motion is produced between shell and the first damping body, this motion is subject to shearing force by making the silicone oil between the first damping body and shell, meanwhile, the second damping body that rotary inertia is bigger than the first damping body will vibrate with the speed less than the first damping body, then relative motion can also be produced between the first damping body and the second damping body, this motion is also affected by shearing force by making the silicone oil between the first damping body and the second damping body, relative sliding will be produced by between each layer of silicone oil of shearing force, each layer silicone oil of relative sliding is by frictional heat and then the energy consuming vibration, thus reducing the torsional amplitudes of bent axle.
The effect of this programme is: by two damping bodies longitudinally disposed in hydraulic chamber, it it is wherein one-level vibration damping between the first damping body and shell, it is two grades of vibration dampings between second damping body and the first damping body, therefore this programme is under the premise meeting damping requirements, can effectively reduce the size of vibroshock, the effective use scope expanding vibroshock.
Further, shell is additionally provided with sealing ring with the place of cooperation of side cover, and sealing ring prevents the silicone oil in hydraulic chamber from leaking on the one hand, and sealing ring also can prevent foreign matter entrance hydraulic chamber from having influence on the normal operation of vibroshock on the other hand.
Further, first damping body place is additionally provided with the shading ring of isolation the first damping body and shell, shading ring is mainly used for isolating shell and the first damping body, shading ring is arranged on the first damping body, therefore when bent axle drives shell that vibration occurs, shading ring with the speed vibration less than shell, the little abrasion that can reduce shading ring of speed of shading ring, extends the service life of shading ring with the first damping body.
Further, shell is additionally provided with some radiating ribs, radiating ribs is the radiating ribs with tapering, radiating ribs can increase the contact area of shell and air, improve the heat-sinking capability of shell, after the heat of silicone oil generation is delivered on shell, heat can be distributed by shell timely and effectively, so that the silicone oil in hydraulic chamber works all the time in suitable temperature.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Accompanying drawing labelling in Figure of description includes: shell 1, side cover 2, sealing ring 3, hydraulic chamber's the 4, first damping body the 5, first bolt 6, shading ring the 7, second damping body the 8, second bolt 9, oil filler point 10.
Embodiment is substantially as shown in Figure 1: two grades of silicon oil dampers, including shell 1, shell 1 is connected with outside bent axle, it is provided with some radiating ribs at the outer contour place of the left side of shell 1 and upside, radiating ribs can increase the contact area of shell 1 and air, improving the heat-sinking capability of shell 1, after the heat of silicone oil generation is delivered on shell 1, this heat can be distributed timely by shell 1 by radiating ribs.Radiating ribs is the radiating ribs with tapering, and wherein radiating ribs is wider with the side that shell 1 connects, and is additionally provided with, in radiating ribs and shell 1 joint, the circular arc chamfering preventing stress from concentrating.
