Abstract
A simple and compact disk brake mechanism which includes a housing having a pair of slightly separated flat guide walls, a plate-like brake member in the housing which is slideable against the disk brake, and a plate-like camming member slideable in the housing and moveable transverse to the braking member to advance the braking member against the disk brake. The housing also includes a spacer plate with a portion that reaches around the disk brake and against an area of the disk brake opposite the plate-like braking member.
Claims5
A brake mechanism for holding a brake disk against rotation comprising:
- a housing;
- a brake member mounted on said housing to move against and away from the brake disk;
- a camming member mounted on said housing to move transverse to the direction of movement of said brake member;
- and
- means for advancing said camming member against said brake member to move said brake member into engagement with said brake disk;
- both of said members formed of metal plates of substantially the same thickness and having edges;
- said housing comprising a pair of housing parts having flat surfaces spaced apart slightly more than the thickness of said metal plates that form said members of closely guide said members, and said members being slidably disposed between said housing parts and free of pivotal connection to said housing and in direct edge contact with each other.
A disk brake mechanism for braking a rotatable brake disk comprising:
- a housing having a pair of housing parts with flat surfaces facing each other;
- said housing including a first plate-like shim portion between said pair of housing parts forming an outside corner with a pair of outside edges angled about 90.degree. from each other;
- said housing including a second plate-like shim portion between said pair of housing parts forming an outside corner with a pair of outside edges angled about 90.degree. from each other and spaced from said inside edges to leave two substantially perpendicular passages between them, with a first of said passages extending substantially perpendicular to the plane of said brake disk;
- a brake member substantially in the form of a plate closely slideably received between the edges froming said first passage that extends perpendicular to said disk and between said flat surfaces of said housing parts;
- a camming member directly in engagement with said brake member and substantially in the form of a plate of the same thickness as said brake member closely slideably received between the edges of the second of said passages and between said flat surfaces of said housing parts;
- means for advancing said camming member towards said brake member;
- said members being free of pivotal connection to said housing;
- and a plate-like spacer with faces parallel to the faces of said brake and camming members, said spacer having a first, portion lying on either side of said brake and camming members and a second portion which includes a pair of arms extending around the disk and a projection extending towards said brake member in substantially the same plane thereof and slightly spaced from the brake disk, to back up a brake disk location opposite the brake member.
