Abstract
A brake or clutch has a pair of opposed, finned, heat dissipating discs between which are mounted back-to-back pistons for forcing generally kidney-shaped friction pads into engagement with inner surfaces of the discs. The friction pads are readily removable by loosening a thumbscrew which holds a torque post in locking position and rotating the torque post to an unlocked position. A fin arrangement for good heat dissipation and a novel hub arrangement are shown.
Claims17
An assembly for use in a friction coupling mechanism of the type wherein relative rotation between two bodies is controlled by selective engagement of friction members, comprising a body carrying at least one friction member and a locking torque post extending transversely across said body and normally holding said friction member in a working position, said torque post being releasable from a locking position and movable to allow sliding removal of the friction member and wherein said torque post is secured to said body by a thumbscrew which can be manipulated to release said torque post from its locking position without removal of the thumbscrew.
A brake or clutch having a pair of spaced, opposed friction discs and a module carrying a pair of back-to-back pistons positioned between said friction discs for forcing friction members into contact with said discs to engage the brake or clutch, said friction members being normally held in working position in front of each piston by a torque post, said torque post being movable to release said friction members for removal of the friction members from said working position said friction members being generally kidney-shaped pads with cut out portions to receive posts which prevent undesired movement of the pads and said pistons being generally kidney-shaped in cross-section.
In a brake or clutch of the type having a pair of spaced, opposed friction discs for engagement by outward motion of friction members located between inner faces of the friction discs, a hub upon which said discs are mounted for rotation with an axial shaft, said hub having beveled surfaces which are at an acute angle with respect to the axis of said shaft and said discs being secured to said hub by fasteners passing through said discs perpendicularly to said beveled surface.
In a friction coupling mechanism of the type having a pair of opposed friction discs secured by a hub to a shaft for rotation with the shaft and at least one pair of back-to-back pistons arranged between inner surfaces of said discs for urging friction members into engagement with said inner disc surfaces, a module carrying said pistons having a plurality of bearing means for rolling alignment on said hub between said discs wherein each said bearing means includes shaft means and wheels on said shaft means on opposite sides of said module for contacting grooves in an outer, generally cylindrical surface of said hub.
A friction coupling mechanism for regulating relative rotational motion between two bodies comprising:
- a shaft;
- a hub mounted on said shaft for rotation therewith, said hub having a generally cylindrical outer surface concentric with said shaft and beveled surfaces tapered toward said shaft;
- a pair of finned friction discs mounted on said hub by fasteners at said beveled hub surfaces, said friction discs being tapered in a radially outward direction from said hub;
- and at least one module carrying a pair of back-to-back piston assemblies for forcing friction members into contact with inner surfaces of said discs, said friction members being slidably releasable from a working position facing said discs for removal of the friction members.
