Description

The extremely unidirectional conversion automatic stepless speed variator of two changeover panel relay type hyperbolics three

The present invention is that application number is a kind of new implementation type of 88100054X " automatic stepless speed-variator with hyperbela three stage unidirectional converting system " that application for a patent for invention proposed.

Application number is that the implementation methods of 88100054X " two by the extremely unidirectional conversion automatic stepless speed variator of line three " that patent application proposed is: (1) input, the hyperbolic drive plate of output assembly and the side that the hyperbolic changeover panel places the chain runner plane respectively, four also corresponding sides that are equipped with the hyperbolic changeover panel that place chain runner of hyperbolic sliding lever, and cooperate connection with four hyperbola chutes of hyperbolic changeover panel.(2) spiral converter places on input, the output shaft and is in the side that is equipped with the hyperbolic changeover panel of chain runner.

" automatic stepless speed-variator with hyperbela three stage unidirectional converting system " of Shi Shiing as stated above, at least have three big shortcomings: the adjacent hyperbolic sliding lever of each assembly two is imported, exported in (1) when device is in certain operation point, wherein the arm of force of the moving lever of a pair of flexural slip will " by " fulcrum of another hyperbolic sliding lever, and this fulcrum links owing to the hyperbola chute with the hyperbolic changeover panel, thereby the arm of force of above-mentioned hyperbolic sliding lever can't " by ", this has just dwindled the slewing range of speed changer to a great extent.(2) since hyperbolic drive plate and hyperbolic changeover panel upper edge circumferentially uniform hyperbola chute respectively two rims circumferentially are divided into four, and each hyperbola chute certain space of accounting for again and making progress in two dish weeks itself, therefore the hub portions of two dishes are very weak; And when mesh rod or hyperbolic sliding lever were in the edge of two dishes, the above-mentioned hub portions of two dishes will bear maximum circumferential stress, and this has just limited the bearing capacity of speed changer to a great extent.(3) accounted for bigger axial space so the structurally not enough compact and reasonable of speed changer of the spiral converter that is in chain runner plane one side.

In order to overcome the above-mentioned shortcoming of speed changer, inventor spy provides a kind of new implementation methods, the speed changer of implementing with this method can reach or approaching theoretic slewing range, and its bearing capacity raising and compact structure are reasonable, and other performances also make moderate progress simultaneously.
