The rotation riveter skills for crossing pedestal, cover board is fixed；Main spring is helical spring, is set in the outside of pedestal, two ends with two
The end of rocking arm is fixedly connected, for two rocking arms to be tensioned, the final tension that belt is provided.
Preferably, the damping fin II is positioned by protrusion and the pit on auxiliary spring retainer.
Preferably, damping fin III is positioned by protrusion and the pit on seat surface.
Preferably, the auxiliary spring retainer is mutually positioned with cover board by mutual notch and protrusion in the circumferential, into
And prevent auxiliary spring retainer from rotating.
The two-way automatic tensioner of the brachiums such as the present invention, spring torque are generated by a helical spring less than two circles；Damping
Torque provides axial compressive force, two rocking arms and a pedestal by auxiliary spring, any relative rotary motion between three, all
It will produce frictional damping.
The two-way automatic tensioner of the brachiums such as the present invention has the characteristics of simple and compact for structure, function can be adjusted flexibly.Institute
With during application is matched, the flexibility with height disclosure satisfy that the design requirement of each intermediate item；It is at low cost simultaneously.
Description of the drawings
Fig. 1 is the explosive view of the equal two-way automatic tensioner of brachiums of the embodiment of the present invention.
Fig. 2 is the structural schematic diagram of the equal two-way automatic tensioner of brachiums of the embodiment of the present invention.
Specific implementation mode
Technical solution of the present invention is discussed in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, present embodiment discloses a kind of two-way automatic tensioners of equal brachiums, by pedestal 8, Rocker arm assembly I
10, Rocker arm assembly II 6, sliding bearing 7, three pieces damping fin 4, auxiliary spring retainer 3, auxiliary spring 2, cover board 1 and main spring 5 assemble
It forms.
Pedestal 8：It is the supporting body of all parts of tensioning wheel, while its end can be with opponent's part intelligent electric machine
Procapsid connects, for installing fixed Dual directional tightener in motor.
Sliding bearing 7：It is mounted on 8 center cylinder of pedestal by keyway, is used as bearing, between base body and two rocking arms
Between assembly endoporus.Two rocking arm rotary motions on sliding bearing.
Three pieces damping fin 4：For in rocking arm rotary course or two Rocker arm assemblies in pedestal rotary course relative to generating
Friction, and then generate the required damping torque of train wheel operation.
Auxiliary spring 2：For providing the surface pressure during damping piece friction operation.
Auxiliary spring retainer 3：Installation site for positioning pressure spring.
Cover board 1：Three pieces damping fin 4 for will be inserted on sliding bearing 7, Rocker arm assembly I 10, Rocker arm assembly II 6, secondary bullet
Spring 2, auxiliary spring retainer 3 compress, are fixed in the axial direction.Eventually by the rotation riveter skills of pedestal 8, cover board 1 is fixed.
Rocker arm assembly I 10, Rocker arm assembly II 6：As two tensioner arms of tensioning wheel, centre bore is sleeved on sliding bearing 7,
Two nose circle faces rub with damping fin 4, generate frictional damping, and installation band wheel assembly in end coordinates with belt.
Main spring 5：Two ends are fixedly connected with the end of two rocking arms, final to provide for two rocking arms to be tensioned
The tension of belt.
The two-way automatic tensioner of the brachiums such as the present invention：
Spring torque：It is generated by helical spring, main purpose is to provide the belt operating tension of system.
Damping torque：Including the frictional damping torque in each rocking arm course of work, by the disc of rocking arm in rotary course
In with damping fin rub generate.Meanwhile when two Rocker arm assemblies are relatively motionless, when being rotated as a whole relative to pedestal,
Also an equal amount of damping torque is will produce, this damping torque is Dual directional tightener in the process for carrying out two-way decoupling to system
Middle systems stabilisation is required.
This design structure is compact, and the not too many special material of the material that parts use, cost compares relatively low.
Function adjusts：
A. belt tension：By adjusting the line footpath of helical spring, you can to adjust its spring rate, and then change tensioning wheel
Spring torque, the final belt tension for changing system.
B. frictional damping：By adjusting the rigidity of auxiliary spring, the normal pressure in damping fin friction process can be adjusted, finally
The purpose of adjustment product damping torque may be implemented.So this design has application aspect the flexibility of height.
The characteristics of brachiums such as the present invention two-way automatic tensioner：
1. spring designs：Spring torque is generated by helical spring by the relative rotation of two ends.
2. damping pressure source：Auxiliary spring is provided and is needed in damping piece friction process by the transmission of auxiliary spring retainer
Axial normal pressure.
3. damping mechanism structure design：A piece of damping piece is positioned among two rocking arms；Another damping fin is positioned over and shakes
Between arm assembly I and compression spring retainer, and damping piece is positioned by protrusion and the pit on auxiliary spring retainer；Third
Piece damping fin is positioned between Rocker arm assembly II and seat surface, and damping fin is positioned by protrusion and the pit on seat surface.
Intermediate damping fin and two Rocker arm assemblies are rotated around sliding bearing.Auxiliary spring retainer passes through mutual notch and protrusion with cover board
It is mutually positioned in the circumferential, and then prevents auxiliary spring retainer from rotating.
Such as belt can be connected between crankshaft pulley, electrical machine belt pulley and Water-pump belt wheel, pass through Rocker arm assembly I, rocking arm
The belt wheel of assembly II compresses belt and provides tension.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, although with reference to aforementioned reality
Applying example, invention is explained in detail, for those skilled in the art, still can be to aforementioned each implementation
