Abstract
A disc brake assembly comprises a housing affixed to a non-rotatable member and having a through-hole therein. A cylinder is slidably fitted in the through-hole in the housing and has a pressure oil inlet, and a piston therein in sliding relation therewith. A disc is rotatable together with a rotating member, and a yoke is affixed to the cylinder and is movable with the cylinder. A member movably couples the yoke to the housing. A first friction pad is supported by the yoke and is adapted to be urged against or detached from one side of the disc, and a second friction pad is mounted on one end of the piston and is adapted to be urged against or detached from the other side of the disc.
Claims4
A disk brake comprising:
- a housing affixed to a non-rotatable member and having a through-hole therein;
- said through-hole having a large diameter portion and small diameter portion, said large diameter portion being of a greater length than said small diameter portion;
- a cylinder slidingly fitted in the large diameter portion of said through-hole and having a pressure fluid inlet;
- a piston having an outer surface of uniform diameter throughout the length thereof fitted within and in sliding contact with said cylinder and said small diameter portion of said through-hole;
- said cylinder and piston defining therebetween single chamber means for receiving fluid through said inlet and for moving said cylinder and piston longitudinally with respect to each other;
- a disk rotatable together with a rotating member;
- a yoke affixed to said cylinder and movable with said cylinder;
- means for coupling said yoke to said housing in a movable manner;
- a first friction pad supported by said yoke and adapted to be urged against or detached from a first side of said disk;
- and
- a second friction pad mounted on one end of said piston and adapted to be urged against or detached from a second side of said disk.
