Abstract

The utility model discloses a shock absorber which is small in size and can ensure coaxiality between a belt wheel disc and a hub, and overcomes the defects that a crankshaft shock absorber in the prior art is large in size and coaxiality is difficult to ensure between the belt wheel disc and the hub. An engine crankshaft shock absorber comprises a crankshaft and the hub arranged on the crankshaft, wherein the belt wheel disc which is coaxial with and connected with the hub is arranged on the hub. An inertia ring is arranged between the belt wheel disc and the hub, a rubber ring is arranged between the inertia ring and the belt wheel disc, the outer side of the rubber ring is connected with the inner side of the belt wheel disc, and the inner side of the belt ring is connected with the outer side of the inertia ring. The engine crankshaft shock absorber is suitable for occasions where the existing crankshaft shock absorber is applied, and has the advantages of fully ensuring the coaxiality between the belt wheel disc and the hub and being stable in whole structure.

Description

A kind of engine crankshaft vibration damper
Technical field
The utility model relates to a kind of vibrations restraining device, relates in particular to a kind of engine crankshaft vibration damper.
Background technique
In order to reach the purpose of subduing the vibrations on the automobile engine crankshaft, means commonly used are in crankshaft end the rubber damping formula crankshaft vibration damper of being made up of wheel hub, rubber ring, inertia ring, pulley disc to be installed.Existing crankshaft vibration damper adopts external inertia ring, also is that inertia ring is located at the pulley disc outside, is connected through rubber between pulley disc and the wheel hub.Yet inertia ring is located at pulley disc and is made that outward the total volume is bigger; And be connected through rubber between pulley disc and the wheel hub, rubber itself has elasticity, under vibrations and pressure, is easy to distortion, therefore is difficult to guarantee the coaxality of pulley disc and wheel hub.
Chinese patent publication number CN101886685A; In open day on November 7th, 2010, the name of invention is called a kind of vibration damper assembly, and this application case discloses a kind of vibration damper assembly; Comprise vibration damper installation shaft, spoke and wheel hub; Outside wheel hub, play the belt pulley of inertia disk effect through second level rubber ring setting, second level inertia ring is set on belt pulley, described wheel hub front end also parallel connection is provided with first order rubber ring and first order inertia ring.In order to eliminate the vibration that bent axle single order vibration frequency causes, described first order rubber ring and first order inertia ring constitute the torsional vibration damper of bent axle single order vibration frequency.Described first order inertia ring is in the inertia ring of the second level.It is big and be difficult to guarantee the coaxality between pulley disc and the wheel hub that its deficiency is still whole vibration damper structural volume.
The model utility content
It is big and be difficult to guarantee the deficiency of the coaxality between pulley disc and the wheel hub that the utility model has overcome existing crankshaft vibration damper volume, provides a kind of volume less and can guarantee the vibration damper of the coaxality between pulley disc and the wheel hub.
The utility model is realized through following technological scheme:
A kind of engine crankshaft vibration damper; Comprise bent axle, be located at the wheel hub on the bent axle; Described wheel hub is provided with pulley disc coaxial with wheel hub and that link to each other, is provided with inertia ring between described pulley disc and the wheel hub, is provided with rubber ring between described inertia ring and the pulley disc; The described rubber ring outside links to each other with pulley disc is inboard, and described rubber ring inboard links to each other with the inertia ring outside.Pulley disc is directly to link to each other with wheel hub, compares pulley disc of the prior art and wheel hub through the situation that flexible rubber links to each other, and has the fixing advantage of relative position, also promptly has the advantage that can better guarantee the two coaxality.And inertia ring is built in pulley disc, does not occupy the space outside the pulley disc outer ring, has guaranteed that the vibration damper overall volume is less.
As preferably, described pulley disc inboard is provided with groove, and described rubber ring is provided with the convexity corresponding with groove.Groove and the convexity on the rubber ring in the pulley disc can be worked in coordination, and play the reinforcement effect of interosculating between the two, can guarantee fully that rubber ring is difficult for displacement, keep vibration damper integrally-built stable.
As preferably, described wheel hub inner ring is provided with the positioning boss of ring, and described positioning boss is coaxial with wheel hub.Positioning boss is as the connection assist between bent axle and the vibration damper, and fixing vibration damper is kept the coaxality of itself and bent axle.
As preferably, described wheel hub links to each other through the bent axle connecting sleeve with bent axle, and described bent axle connecting sleeve and wheel hub, positioning boss all recline.The bent axle connecting sleeve can increase and vibration damper between the surface of contact device, improve contact stabilization, stable when guaranteeing vibration damper work.
As preferably, described bent axle is provided with the vibration damper fixing bolt, and described vibration damper fixing bolt contacts with positioning boss.Through the vibration damper fixing bolt vibration damper is installed on the bent axle, has further guaranteed the stability of vibration damper, help keeping the coaxality between belt pulley pulley sheaves and the wheel hub simultaneously.
Therefore, the beneficial effect of the utility model is: (1) can fully guarantee this two coaxality because pulley disc directly links to each other with wheel hub; (2) have a plurality of reinforcement linkage structures, can fully guarantee whole the stablizing of vibration damper.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: bent axle 1, wheel hub 2, pulley disc 3, inertia ring 4, rubber ring 5, convexity 6, positioning boss 7, bent axle connecting sleeve 8, vibration damper fixing bolt 9.
Embodiment
Through embodiment, the technological scheme of the utility model is done further explanation below in conjunction with accompanying drawing:
A kind of engine crankshaft vibration damper as shown in Figure 1; Comprise bent axle 1, be located at the wheel hub 2 on the bent axle 1; Described wheel hub 2 is provided with pulley disc 3 coaxial with wheel hub 2 and that link to each other, is provided with inertia ring 4 between described pulley disc 3 and the wheel hub 2, is provided with rubber ring 5 between described inertia ring 4 and the pulley disc 3; Described rubber ring 5 outsides and 3 inboard linking to each other of pulley disc, described rubber ring 5 inboards link to each other with inertia ring 4 outsides.Described pulley disc 3 inboards are provided with groove, and described rubber ring 5 is provided with the convexity corresponding with groove 6.Groove in the pulley disc 3 and the convexity 6 on the rubber ring 5 can be worked in coordination, and play the reinforcement effect of interosculating between the two, can guarantee fully that rubber ring 5 is difficult for displacement, keep vibration damper integrally-built stable.Described wheel hub 2 inner rings are provided with the positioning boss 7 of ring, and described positioning boss 7 is coaxial with wheel hub 2.Positioning boss 7 is as the connection assist between bent axle 1 and the vibration damper, and fixing vibration damper is kept the coaxality of itself and bent axle 1.Described wheel hub 2 links to each other through bent axle connecting sleeve 8 with bent axle 1, and described bent axle connecting sleeve 8 all reclines with wheel hub 2, positioning boss 7.Bent axle connecting sleeve 8 can increase and vibration damper between the surface of contact device, improve contact stabilization, stable when guaranteeing vibration damper work.Described bent axle 1 is provided with vibration damper fixing bolt 9, and described vibration damper fixing bolt 9 contacts with positioning boss 7.Through vibration damper fixing bolt 9 vibration damper is installed on the bent axle 1, has further guaranteed the stability of vibration damper, help keeping the coaxality between belt pulley pulley sheaves and the wheel hub 2 simultaneously.
