MODULAR BRARES AND CLUTC~S
BACRGROUND OF TH~ INYENTION
._ .
Field of the Invention -This invention relates to brakes and clutches having a special hub structure and permitting easy maintenance.
Discussion of the Prior Art . . .
United States patent application Serial No. 095,201 discloses a double disc brake or clutch wherein friction pads are readily removable. Other arrangements for quick change of brake shoes are shown in U.S. patent ~o. 3,388,775 to Baynes et al. and in Rlaue patent No. 3,885,650. The desirability of being able to remove and replace worn friction material easily has been recognized.
It has also been known that the use of interchangeable parts in brakes and clutches is desirable, as shown, for example in U.S. patent 3,964,583 to ~ontalvo.
Summary of the Invention A single disc, single acting brake or clutch can incorporate one or more pneu~atically actuated piston and cylinder assemblies for urging friction material into contact with a disc rotatable relative to the body which carries the piston and cylinder assemblies.
When operated as a brake, a ~tationary body i8 engaged with a rotating body to stop the motlon thereof. When operated aq a clutch, upon engagement, the two bodies move together.
The friction coupling mechanism of the present invention has a novel hub which can be used in either a brake or a clutch configuration, thus reducing the necessary inventory of replacement parts. Identical piston and cylinder assemblies, discs and mounting spiders can also be used in either brakes or clutches.
The piston and cylinder assembly lor assemblies) is mounted on a spider. In the case of a brake the spider is fixed to a machine frame. In the case of a clutch the spider is mounted on a rotatable shaft. In either case, friction material carried on the outer face of the piston is moved upon actuation into engagement with an opposed disc, which is preferably finned for hea~ dissipation.
The central hub of the assembly is so structured that in one position it can be used in a brake configuration and in a reversed position, the hub can function in a clutch. Adapter 33, bearing 35, adapter fastener 34 are added for the in-drive function as a clutch.
These simplifications, together with easy removal of friction material, provide for economical service and replacement of parts.
One or more piston and cylinder assemblies, which have disc-shaped cyinder base plates, are mounted by ~eans of screws on a spider. These piston and cylinder assemblies have hollow cylindrical torque posts extending from the cylinder base plates and attached thereto by removable screws. The torque posts hold generally disc-shaped pads of friction ~aterial in place, so that the removal of a torque post makes it possible to remove the friction pad by sliding the pad radially outward.
2022~93 Upon removal of an air fitting through which air under pre~sure enters the cylinder to actuate the piston, and removal of mounting screws, the entire piston and cylinder assembly, including the cylinder base plate, can be removed for service.
The friction material pads face a finned disc against which they are pushed when air under pressure is fed into the cylinders to engage the brake or clutch. When air pressure is relieved the friction pads retract and disengage.
When the central hub of the mechanism is secured to a rotatable shaft and the spider is attached to a machine frame, the mechanism operates as a brake. When the hub position is reversed and the hub is attached to the spider, a spocket adapter mounts the finned disc to a driven shaft and the mechanism functions as a ciutch. Upon engagement, the driven shaft rotates the hub, which in turn rotates the finned disc and the spider rotates therewith.
Thus the device can function as either a brake or a clutch, because of its reversible hub.
These and other objects and advantages of the single disc friction coupling mechanism of the invention will be more fully understood from the following detailed description of the invention when that description is read in view of the accompanying drawing figures.
Brief Description of the Drawings In the drawings, like reference numerals designate like parts.
Pig. 1 is an exploded view of a brake according to the invention.
Fig. 2 is a cross-sectional view of the assembled brake of Fig. 1.
2022~93 Fig. 3 is an exploded view of the mechanism in a clutch configuration; and Fig~ 4 is a cross-sectional view of the assembled clutch of Fig. 3.
Detailed Description of Preferred Embodiments Figures 1 and 2 show a brake according to the invention. Piston and cyinder assemblies 10, of which six are shown in Fig~ 1, al~hough any number, and in larger sizes a number greater than six, can be used, are attached through cylinder base plates 11 to a cylinder mounting plate or spider 12 by mounting screws 13. In the illustrated, preferred embodiment, two screws 13 secure each piston and cyinder assembly 10 to the spider 12 The cylinder mounting plate or spider 12 i&, in turn, secured to a machine frame (not shown) by reaction bolts 14 which pass through a slot 15 in the periphery of the spider 12 in the brake configuration of Figs. 1 and 2.
Each piston and cylinder assembly 10 comprises the cylinder base plate 11, a piston assembly 16, a ring shaped piston collar 17, cylindrical torque posts 18 (two per piston cylinder assembly~ and removable torque post screws 19 which serve to secure torque posts 18 to the cylinder base plate 11, which is attached to the spider 12 by mounting screws 13. The torque posts 18 extend from the piston collar 17 through slots 20 in the periphery of a pad 21 of friction material, which upon engagement with the friction disc 22 frictionally couples the disc 22 with the spider 12 and thus to the machine frame, stopping or controlling the relative rotation of the parts. The friction disc 22 is preferably finned as shown for dissipation of the heat generated upon engagement of the brake.
All of the parts described so far, except for the ` 2022~93 reaction bolts 14, are also present ln the clutch configuration of the mechanism as shown in Figs. 3 and 4. Figs. 2 and 4 also show the air fittings 23 by means of which air under pressure is introduced in the cylinders of the piston and cylinder assemblies 10 to move the friction pads 21 outward into enga~ement with the friction disc 22. It is also possible to actuate the piston and cylinder a~semblies hydraulically, as will be understood by those acquainted with brakes and clutches.
The central hub 24 is a generally cylindrical body with a peripheral flange 25 at one end. In the brake configuration illustrated in Fig~. 1 and 2, the hub 24 is attached to the friction disc 22 for movement therewith by means of disc hub mounting bolts 26. A bearing 27 and a bearing sleeve 28 surround the central hub 24 and the bearing and bearing sleeve have retaining rin~s 29 and 30 respectively. A suitable grease gasket 31 is located between the hub 24 and the friction disc 22.
Upon actuation of the piston and cylinder assemblies in the brake configuration of Figs. 1 and 2, the friction pads 21 engage the friction disc 22 and a shaft (not shown) keyed to tbe hub 24 is restrained from rotation relative to the machine frame to which the cylinder mounting plate or spider is attached by the reaction bolts 14.
When the mechanism is employed as a clutch the hub 24 and the parts associated therewith, i.e. the bearing 27, bearing sleeve 28, retaining rings 29 and 30 and grease gasket 31 are inverted from the position shown in Figs. 1 and 2, to that shown in Figs. 3 and 4, so that the flange 25 of the hub 24 faces the spider 12 and is secured thereto by means of bolts 32 as best shown in Fig. 4. In the brake configur?tion of Figs. 1 and 2 the bolts 32 secure the bearing sleeve 28 to the spider.
Reverting to Figs. 3 and 4 which show the mechanism as a clutch, it can be seen that a sprocket adapter generally designated by reference numeral 33 i8 attached to the disc 22 by means of fasteners 34 and i8 carried by bearing 35 on the driven shaft (not shown).
Screws 34 affi~ the sprocket adapter 33 to the disc 22 and bearing sleeve 28. In this clutch configuration, an additional bearing 35 is provided as shown in Figs. 3 and 4. The sprocket adapter 33 can thus transmit rotational motion from a drive shaft to the friction disc 22 at a predetermined speed, clutching the spider 12 which is mounted on the central hub 24 and carried by a driven shaft (not shown in the drawings).
The fact that the identical hub and other parts can be used in either a brake or a clutch, by ~imply turning the hub through 180 and adding the sprocket adapter for use as a clutch, means that fewer special parts need be manufactured, and spare parts inventories are greatly reduced. In the case of either brake or clutch use, the pads of friction material 21 can be easily replaced by removal of the torque posts and screws 18 and 19 without disassembling the entire device, and entire piston and cylinder assemblies 10 are also readily removable.
Various modifications, substitutions and variations of the foregoing preferred embodiments will suggest themselves to those of skill in the art, and therefore are within the spirit and scope of the invention.

Detailed Description of Preferred Embodiments Figures 1 and 2 show a brake according to the invention. Piston and cyinder assemblies 10, of which six are shown in Fig~ 1, al~hough any number, and in larger sizes a number greater than six, can be used, are attached through cylinder base plates 11 to a cylinder mounting plate or spider 12 by mounting screws 13.

Each piston and cylinder assembly 10 comprises the cylinder base plate 11, a piston assembly 16, a ring shaped piston collar 17, cylindrical torque posts 18 (two per piston cylinder assembly~ and removable torque post screws 19 which serve to secure torque posts 18 to the cylinder base plate 11, which is attached to the spider 12 by mounting screws 13. The torque posts 18 extend from the piston collar 17 through slots 20 in the periphery of a pad 21 of friction material, which upon engagement with the friction disc 22 frictionally couples the disc 22 with the spider 12 and thus to the machine frame, stopping or controlling the relative rotation of the parts. The friction disc 22 is preferably finned as shown for dissipation of the heat generated upon engagement of the brake.
All of the parts described so far, except for the ` 2022~93 reaction bolts 14, are also present ln the clutch configuration of the mechanism as shown in Figs. 3 and 4. Figs. 2 and 4 also show the air fittings 23 by means of which air under pressure is introduced in the cylinders of the piston and cylinder assemblies 10 to move the friction pads 21 outward into enga~ement with the friction disc 22. It is also possible to actuate the piston and cylinder a~semblies hydraulically, as will be understood by those acquainted with brakes and clutches.
The central hub 24 is a generally cylindrical body with a peripheral flange 25 at one end. In the brake configuration illustrated in Fig~. 1 and 2, the hub 24 is attached to the friction disc 22 for movement therewith by means of disc hub mounting bolts 26. A bearing 27 and a bearing sleeve 28 surround the central hub 24 and the bearing and bearing sleeve have retaining rin~s 29 and 30 respectively. A suitable grease gasket 31 is located between the hub 24 and the friction disc 22.
Upon actuation of the piston and cylinder assemblies in the brake configuration of Figs. 1 and 2, the friction pads 21 engage the friction disc 22 and a shaft (not shown) keyed to tbe hub 24 is restrained from rotation relative to the machine frame to which the cylinder mounting plate or spider is attached by the reaction bolts 14.
When the mechanism is employed as a clutch the hub 24 and the parts associated therewith, i.e. the bearing 27, bearing sleeve 28, retaining rings 29 and 30 and grease gasket 31 are inverted from the position shown in Figs. 1 and 2, to that shown in Figs. 3 and 4, so that the flange 25 of the hub 24 faces the spider 12 and is secured thereto by means of bolts 32 as best shown in Fig. 4. In the brake configur?tion of Figs. 1 and 2 the bolts 32 secure the bearing sleeve 28 to the spider.
Reverting to Figs. 3 and 4 which show the mechanism as a clutch, it can be seen that a sprocket adapter generally designated by reference numeral 33 i8 attached to the disc 22 by means of fasteners 34 and i8 carried by bearing 35 on the driven shaft (not shown).
Screws 34 affi~ the sprocket adapter 33 to the disc 22 and bearing sleeve 28. In this clutch configuration, an additional bearing 35 is provided as shown in Figs. 3 and 4. The sprocket adapter 33 can thus transmit rotational motion from a drive shaft to the friction disc 22 at a predetermined speed, clutching the spider 12 which is mounted on the central hub 24 and carried by a driven shaft (not shown in the drawings).
