Abstract
A driven element (100) has a first sheave (13) and a second moveable sheave (9). The sheaves (9 and 13) are rotatably tied together so that there is no relative motion between the two sheaves (9 and 13).
Claims14
A torque-sensing clutch, comprising:
- a) a cylindrical base member;
- b) a first sheave operatively connected to the cylindrical base member, the first sheave rotatable on the cylindrical base member and being stationary relative to longitudinal movement on the cylindrical base member;
- c) a second sheave longitudinally moveable and rotatable on the cylindrical base member;
- d) a first connector operatively connecting the cylindrical base member to the second sheave for rotating the second sheave and for moving the second sheave longitudinally on the cylindrical base member;
- and
- e) a second connector operatively connecting the first and second sheaves, wherein the first and second sheaves rotate together the rotation of the second sheave causes rotation of the first sheave to rotate together without relative rotation as the second sheave moves longitudinally and reduces belt smear.
A continuously variable transmission driven element for mounting on a rotatable shaft and adapted for use in a belt-type continuously variable transmission operatively connected by an endless belt to a drive element, the driven element comprising:
- a) a post adapted and configured to be operatively connected to a rotatable shaft;
- b) a housing operatively connected to the post, the housing rotatable on the post and being stationary relatively to longitudinal movement on the post;
- c) a first conical-faced belt contacting coaxially mounted sheave portion operatively connected to the housing;
- d) a second conical-faced belt contacting coaxially mounted sheave portion, the second sheave portion longitudinally movable and rotatable on the post;
- e) a connector operatively connecting the first and second sheave portions, wherein rotation of the second sheave portion causes rotation of the first sheave portion and reduces belt smear;
- and
- f) a cam, having a cam surface, operatively connected to the second sheave portion;
- g) a spider operatively connected to the post, the spider having a sliding member which is positioned on the cam surface, wherein rotation of the cam on the spider moves the second sheave portion longitudinally on the post;
- and
- h) a compression spring positioned between the spider and second sheave portion.
A continuously variable transmission driven element for mounting on a rotatable shaft and adapted for use in a belt-type continuously variable transmission operatively connected by an endless belt to a drive element, the driven element comprising:
- a) a post adapted and configured to be operatively connected to a rotatable shaft;
- b) a housing operatively connected to the post, the housing rotatable on the post and being stationary relatively to longitudinal movement on the post;
- c) a first conical-faced belt contacting coaxially mounted sheave portion operatively connected to the housing;
- d) a second conical-faced belt contacting coaxially mounted sheave portion, the second sheave portion longitudinally movable and rotatable on the post;
- e) means for connecting the first and second sheave portions, wherein rotation around the post by both sheave portions is equivalent, thereby reducing belt smear;
- f) said connecting means providing for longitudinal movement of the second sheave portion on the post;
- g) a cam, having a cam surface, operatively connected to the second sheave portion;
- h) a spider operatively connected to the post, the spider having a sliding member which is positioned on the cam surface, wherein rotation of the cam on the spider moves the second sheave portion longitudinally on the post;
- and
- i) a compression spring positioned between the spider and second sheave portion.
