Invention content
The main inventive purpose of the present invention, is to provide a kind of a kind of novel shifting that can improve running car performance well Dynamic section structure.
Technical solution used in the present invention is:A kind of Novel movable section structure, including three pin shaft forks, three pivot pin of drum type, side Shape block, cages for needle, dolioform needle roller.The axis of three and three pivot pin of drum type adaptation are laid on the inner hole wall of three pin shaft forks To groove.Twice and three pivot pin of drum type adaptation axial groove between be equipped with together be used for place square block axial groove it Between, it is respectively provided with a needle roller between two sides of square block and the corresponding side for the axial groove for placing square block and protects Hold frame.Cages for needle is equipped with several needle roller mounting grooves, sets that there are one dolioform needle rollers in each needle roller mounting groove, accordingly Two sides of the axial groove for placing square block are equipped with the groove being adapted to dolioform needle roller.Three pivot pin of drum type includes drum Three pivot pin ontology of type and the uniformly distributed positioning protrusion for being convex to corresponding square block being located on three pivot pin ontology of drum type, corresponding side Shape block is equipped with and the hole that is located by connecting of positioning protrusion adaptation, and positioning protrusion, which is inserted in, to be located by connecting in hole, positioning protrusion Coordinate with corresponding square block activity.
Here, square block is far from three pivot pin of drum type and the side adjacent with the slot bottom of axial groove for placing square block It is equipped with gap with the slot bottom of the axial groove for placing square block, therefore square block on the one hand can be with slight oscillatory, simultaneously It can also be with three pivot pin of drum type together along the axial movement of three pin shaft forks.In addition, " being laid with three on the inner hole wall of three pin shaft forks The axial groove in road and three pivot pin of drum type adaptation." in " adaptation " it is intended that these " axial grooves " are according to " three axis of drum type Pin " relative dimensions manufacture, the not tactile company in surface of the bottom surface and side of these axial grooves and " three pivot pin of drum type " that is to say and set There is gap.Structure of the invention is novel, will not be had adverse effect on to running car stationarity, therefore can improve well Running car performance is a kind of very outstanding Novel movable section structure.
Preferably, each cages for needle is equipped with four to six needle roller mounting grooves, it is equipped in each needle roller mounting groove A piece dolioform needle roller, the diameter at dolioform needle roller both ends are 0.75 to 0.85 times of dolioform needle roller maximum gauge.This is preferably Scheme, reasonable for structure, using effect is good.
Preferably, being connected by necking down between three pivot pin ontologies and positioning protrusion.This preferred embodiment is conducive to high quality Ground processes three pivot pin of drum type.
In conclusion the beneficial effects of the invention are as follows:Square block is far from three pivot pin of drum type and and for placing square block The slot bottom of the adjacent side of the slot bottom of axial groove and axial groove for placing square block is equipped with gap, and square block is on the one hand Can be with slight oscillatory, while acceptable and three pivot pin of drum type is together along the axial movement of three pin shaft forks.Structure of the invention is novel, Running car stationarity will not be had adverse effect on, running car performance can be improved well, be a kind of very outstanding Novel movable section structure.
