Abstract
Abstract The present invention relates to a stepless speed changing device and more particularly to the construction of an automatic speed changing device suitable for a vehicle or the like, the centrifugal force of said changing device is produced by the high-speed rotation of a rotating means which enables a plurality of claw blocks fitted pivotedly at a rotating disk to expand outward to increase the outside diameter thereof, and which, after the output of motive force, can produce automatically differential speed ratios of various magnitudes because of the change of said working outside diameters.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
158 words
A centrifugal stepless speed changing device comprising a rotary disk having a top surface and a shallow annular groove at its central portion and a plurality of holes arranged around said shallow groove; a positioning body having a bottom portion with a plurality of grooves, each of which grooves has a bottom surface the bottom portion of said positioning body is mounted on said shallow annular groove of said rotary disk; and a claw blocks set having a plurality of claw blocks are arranged in sequence, each of said claw blocks having a flange at one end and a V-shaped groove at the other end for receiving a belt, a hole is provided adjacent to said flange end, said flanges of said claw blocks are placed on said grooves of the positioning body respectively and assembled together by means of a plurality of bolts through said holes of the claw blocks and the holes of said rotary disk.
Claim 2
Dependent Claim
158 words
A centrifugal stepless speed changing device comprising a rotary disk having a top surface and a shallow annular groove at its central portion and a plurality of holes arranged around said shallow groove; a positioning body having a bottom portion with a plurality of grooves, each of which grooves has a bottom surface the bottom portion of said positioning body is mounted on said shallow annular groove of said rotary disk; and a claw blocks set having a plurality of claw blocks are arranged in sequence, each of said claw blocks having a flange at one end and a V-shaped groove at the other end for receiving a belt, a hole is provided adjacent to said flange end, said flanges of said claw blocks are placed on said grooves of the positioning body respectively and assembled together by means of a plurality of bolts through said holes of the claw blocks and the holes of said rotary disk.
Claim 3
Dependent Claim
20 words
A device according to claim 1, wherein said rotary disk further having a plurality of projections on its top surface.
Claim 4
Dependent Claim
42 words
A device according to claim 1, wherein each of the claw blocks have a linear side and a curve side and the linear side of one claw block is adjacent to the curve side of the next claw block in regular sequence.
Claim 5
Dependent Claim
54 words
A device according to claim 1, wherein one end of an anti-slip belt is mounted on said V-shaped grooves of said claw blocks and another end of said belt is slipped over on a pulley, a spring biased tensioning roller, said roller being mounted beside said biasing a slack side of said anti-slip belt.
Claim 6
Dependent Claim
42 words
A device according to claim 1, wherein the bottom surface of said grooves of the positioning body becomes co-planar with the top surface of said rotary disk when the positioning body is placed in the shallow annular groove of said rotary disk.
