From the accompanying drawing in above-mentioned patent, the turbine both sides of above-mentioned rod-pulling type braking adjusting arm are provided with sealing ring, turbine is avoided to shake in rotation process, reduce turbine abrasion, but sealing ring resistance suffered when can increase turbine rotation is set, thus increase pull bar one-way clutch control worm component load.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is in that to provide a kind of rod-pulling type braking adjusting arm, the problem that there is bigger resistance when it is in that to solve turbine rotation between sealing ring and turbine.
For achieving the above object, this utility model provides following technical scheme: a kind of rod-pulling type braking adjusting arm, including the braking adjusting arm housing being built-in with worm gear and worm screw, the both sides of described worm gear are provided with sealing ring, outside described sealing ring, stator is installed, it is characterized in that, described sealing ring is provided with some first fins on a side end face of worm gear, and described first fin is uniformly distributed on the end face of sealing ring around the center of circle of sealing ring.
This utility model is more preferably: the cross section of described first fin is triangular in shape, arc or circular arc.
By adopting technique scheme, the end face that sealing ring abuts with worm gear arranges the fin of triangle, arc or circular arc to reduce the contact area between sealing ring and turbine end face, reduce the frictional force between sealing ring and turbine.
This utility model is more preferably: the protruding apex of described first fin is provided with first tangent plane parallel with sealing ring end face, and described first tangent plane abuts with the end face of worm gear.
By adopting technique scheme, the area abutted with worm gear due to the fin of triangle, arc or circular arc setting is less, it is easily caused ring wear, turbine is caused to loosen, therefore suitable increase contact area is set by tangent plane, reduce the abrasion of sealing ring, postpone the service life of sealing ring.
This utility model is more preferably: be provided with second fin identical with the first fin shape and structure on one end end face of described sealing ring turbine dorsad.
By adopting technique scheme, what adopt the second fin arranges the resistance reducing between sealing ring and stator so that can produce linkage between sealing ring and turbine, reduces the abrasion of sealing ring further.
This utility model is more preferably: the second cross section area on described second fin is more than the first cross section area on the first fin.
By adopting technique scheme, reduce the abrasion between the second fin and stator, simultaneously, it is to avoid sealing ring rotates and excessively frequently results in flank wear and shine into sealing ring and loosen.
This utility model is more preferably: being provided with the installing hole for installing worm gear on described braking adjusting arm housing, one end of described installing hole is provided with baffle ring, and described stator is set to one.
By adopting technique scheme, the arranging and abut one sealing ring between turbine of baffle ring so that only need to install a stator, the mounting structure of simplification turbine, the difficulty of reduction turbine.
In sum, it is little that this utility model rod-pulling type braking adjusting arm has turbine rotation resistance, the advantage of long service life.

Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described in detail.
It is a kind of embodiment of this utility model pull bar 9 formula braking adjusting arm as shown in Figures 1 to 5, it braking adjusting arm housing 1 including being built-in with worm gear 21 and worm screw 7, including the braking adjusting arm housing 1 being built-in with worm gear 21 and worm screw 7, worm gear 21 and worm screw 7 engage each other, worm screw 7 is socketed on a worm screw axle center 2, braking adjusting arm housing 1 one end connects fork 12 by big bearing pin 15, connect fork 12 by small clevis pin with head 1614 cylinder lever connecting rod 9, big bearing pin 15, small clevis pin with head 1614 is equipped with axis hole through the end, one end connecting fork 12, above-mentioned axis hole is respectively cooperating with connecting big pin 13 and little pin.Pull bar 9 end is provided with worm screw 7 assembly that tooth bar one-way clutch is connected in braking adjusting arm housing 1, the particularly rotation gear in tooth bar one way engagement worm screw 7 assembly of pull bar 9 end, worm screw 7 assembly is installed in the transversely mounted hole 11 in braking adjusting arm housing 1.
As shown in Figure 1, Figure 4 and Figure 5, the both sides of worm gear 21 are provided with sealing ring 4, stator 3 is installed outside sealing ring 4, in the present embodiment, braking adjusting arm housing 1 is provided with the installing hole 11 for installing worm gear 21, one end of installing hole 11 is provided with baffle ring 6, stator 3 is set to one, the arranging and abut a sealing ring 4 between turbine of baffle ring 6 so that only need to install a stator 3, simplify the mounting structure of turbine, reduce the difficulty of turbine.Wherein, sealing ring 4 is provided with some first fins on a side end face of worm gear 21, first fin is uniformly distributed on the end face of sealing ring 4 around the center of circle of sealing ring 4, the cross section of the first fin is triangular in shape, arc or circular arc, in order to reduce the production difficulty of sealing ring 4, in the present embodiment, the cross section of the first fin is triangular in shape.The end face that sealing ring 4 abuts with worm gear 21 arranges the fin of triangle, arc or circular arc to reduce the contact area between sealing ring 4 and turbine end face, reduce the frictional force between sealing ring 4 and turbine.
The protruding apex of the first fin is provided with first tangent plane parallel with sealing ring 4 end face, and the first tangent plane abuts with the end face of worm gear 21.The fin arranged due to triangle, arc or circular arc is less with the area that worm gear 21 abuts, it is easily caused sealing ring 4 to wear and tear, causes turbine to loosen, therefore suitable increase contact area is set by tangent plane, reduce the abrasion of sealing ring 4, postpone the service life of sealing ring 4.
