Description
Technical field
The present invention relates to engineering machinery fields, in particular to a kind of road roller.
Background technology
Vibrated roller is the eccentric moment generated by the high-speed rotating eccentric block in idler wheel, and excitation idler wheel machinery shakes
It is dynamic, to realize the compacting to packing material.The vibration frequency of General Oscillation roller drum from more than ten hertz to 70 more than it is conspicuous
Hereby etc..Mechanical oscillation cannot be contacted in this frequency separation, human body, thus just have idler wheel (hereinafter referred to as vibrating wheels) with
Vibration isolation system between vehicle frame, i.e. shock mitigation system.
Currently, shock mitigation system used in industry is to use damping rubber block, to connect vibrating wheels and vehicle frame.
In the prior art, as shown in Figure 1, in order to ensure the service life of component of machine and the comfort of driver, but it is uncommon
It hopes the exciting force of vibrated roller sufficiently large, using damper 21 spaced-apart of vibrating wheels 3 and vehicle frame, is vibrated with this to reduce
Wheel passes to the vibration of vehicle frame.
Fig. 2 and Fig. 3 is the structural schematic diagram of damper 2, wherein 4 be outer connection sheet, and 5 be connection bolt, and 6 be shock reducing structure,
7 be interior connection sheet.Outer connection sheet 4, connection bolt 5 and interior connection sheet 7 are integral by 6 gluing of shock reducing structure.
As shown in Figure 1, in the left-half of the figure, vibrating wheels are attached with vehicle frame by damper, from figure
For vibrating wheels, left end is vibration end, is connected on vibrating shaft by vibrating motor and generates vibration, then by damper damping, then
It is connected in rack；In the right half part of Fig. 1, right end is the driving end of steel wheel, and drive motor connects damper with speed reducer, is driven
Power acts on damper, drives the vibrating wheels rotation being connect with it, and damper, which plays the vibration of vibrating wheels, to be reduced and filter
Effect.
Vibrated roller still will mainly lean on other than the consolidation effect by the exciting force of vibrating wheels to ensure material
The Gravitative Loads of complete machine could obtain enough exciting forces on material.As how no matter a pile foam vibrate, it is can not
Any compaction force can be generated.General vibrated roller, such as 20 tons of heavy vibrated rollers, the weight of vibrating wheels only account for
Than about one third or so, that is, less than 7 tons, most of weight is on vehicle frame.
As it can be seen that the damper of connection vibrating wheels and vehicle frame, needs to bear the considerable fraction of weight of vehicle frame, then damper
When bearing various service loads, need always there are one on to support vehicle frame conduct oneself with dignity active force.Shape is shut down in road roller
Under state, damper substantially just rises and supports connection function, and main on cross section there are one sizable shearing moment, this power
Square keeps damper shear-deformable, generates plastic deformation afterwards in the course of time, and defective shock absorber or direct shearing is made to be broken.
Therefore, this shearing moment has greatly accelerated the failure process of damper, reduces its service life, also, subtract
Shake device is vibrated roller key components and parts, and value is high, and replacement cost is big.

Similarly, at the driving end of Fig. 4 right ends, because the outer ring of damper 30 and the endoporus of the second driving end holder 70 are to match
The outer end flanging of conjunction relationship, outer ring plays axially position；The outer circle of the inner ring of damper 30 and the first driving end holder 60
It is matching relationship, the flanging of inner ring plays axially position, and therefore, damper 30 is mainly by radial force effect, but this diameter
It is extruding force or drawing force to shock reducing structure 31 to power.
Therefore, end is still either driven in vibration end, mainly by radial force effect, this radial load is damper 30
To the extruding force in a circumferential direction of shock reducing structure 31 or drawing force, and then it is larger because being born on cross section to avoid damper 30
Shearing force.
In the present embodiment, outer ring and inner ring in damper 30 can be 90 ° of flanging form, or other angles
Flanging form, flanging can be not required to, as long as assisting other axially position measures that can also realize.
It is the structural schematic diagram of the damper in another embodiment in Fig. 9, is made of inner ring, shock reducing structure and outer ring,
Inner ring and outer ring is glued or connection is integral, the outer circle cooperation of inner ring and the first vibration end holder 40 by shock reducing structure, outer ring and
The inner hole of second vibration end holder 50.In figure, stop part 80 is screwed on the first vibration end holder 40；Locating part
90 inside the endoporus of the second vibration end holder 50, stop part 80 and locating part 90 position respectively in the axial direction inner ring and
Outer ring, to make damper be fixed on axial determining position.
The rest may be inferred, and also there are many arrangements with locating part 90 for stop part 80, such as locating part 90 and the second vibration end branch
Frame 50 is integrated, a step only in its endoporus；Or one shaft shoulder is set in the outer inner round side of the first vibration end holder 40,
Outer baffle ring (or stop part) is installed in the outside of the second vibration end holder 50, damper can also be made in axially position.
The present embodiment uses one or more damper 30, and idler wheel 20 and vehicle frame 10 are passed through axial assembly, radial carrying
Connection, and realizes the quick despatch mode of damper 30, and damper 30 uses special construction, solid or filling pattern, have on
Lower two radial carrying assembly curved surfaces, there are one axial restraint mounting planes.
Compactor structure in the present embodiment is simple, reliable, easy to assembly；Road roller in the present embodiment is using a kind of complete
New shock-damping structure so that the reliability of the shock-damping structure of road roller has the variation of matter, and directly reduce production and use at
This.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, any made by repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
