Abstract: A torque limiting clutch or coupler is provided for implementation between input and output shafts. A spring biased friction stack assembly establishes a characteristic breakaway torque of the unit. A torque modifying plate is fixed to a pressure plate and, in conjunction with an end plate, defines a ring-like cavity having a bladder therein filled with a fluid. As the torque limiting clutch or coupler begins to rotate, the fluid within the bladder is forced outwardly by centrifugal force and, as the speed increases, the restriction on the fluid radially causes it to begin to move axially, causing the pressure plate to act against the spring bias in one embodiment and to supplement the spring bias in another embodiment, regulating the characteristic breakaway torque as a function of rotational speed.

Abstract: A compact dry power takeoff clutch unit is adapted for interconnection with a flywheel of an engine. A housing is adapted for attachment to the engine and has a plurality of interleaved friction and separator disks maintained therein. A drive ring is connected to the friction disks and to the flywheel for driving the friction disks by the engine. An output shaft is interconnected with the separator disks. A pair of anti-friction bearings are received by the housing and provide the sole support for the output shaft. A pressure plate is configured to be nestingly received by a cup-shaped flywheel in order to maintain certain standardized dimensional constraints. Actuation of the clutch is achieved by a rotary union interposed between the pair of support bearings. A quiescent position for the separator disks is achieved by the mounting of the separator disks between the head and spring of shoulder bolts secured to an output hub mounted upon the output shaft.

Abstract: A hydraulically actuated power takeoff clutch assembly is rigidly coupled to the flywheel of an engine and has an input hub which serves as a gear to drive auxiliary hydraulic pumps. The input hub is a portion of a wet clutch which is hydraulically actuated through a rotary union connected to an output shaft. The serviceable parts of the clutch are secured to the output shaft and are separably removable from the hydraulic power takeoff assembly for servicing. The clutch is of a multiple disk type. An electronic controller monitors the input and output speeds of the hydraulic power takeoff device and is effective to “bump” the unit to accomodate high inertia loads and to further monitor the operation of the device, such that the clutch thereof serves as a torque limiter.

Abstract: A hydrostatic rotary union has a shaft with an axial passage therethrough received within a housing having a radial passage in fluid communication with the axial passage. The shaft and housing have a radial clearance between them which establishes a squeeze film bearing and seal, when in use. End annuluses receive the oil establishing a squeeze film bearing and provide a return path to a supply source. The inner circumferential portion of the housing interfacing with the shaft is preferably of an anti-seizure material, such as bronze. Moreover, the housing and shaft are of materials of different coefficients of thermal expansion, such that excessive heat generated at the interface between the housing and shaft will cause the housing to expand away from the shaft.

Abstract: A hydraulic caliper disk brake (10) according to the present invention includes a caliper base (46) that is supported by a folding triangular base (14) that generally includes a mounting base (30) and a support arm (54). The caliper base (46) is pinned to the mounting base (30) and the support arm (54) such that the caliper base (46) may pivot about the mounting base (30) when the pin connecting the support arm (54) to the mounting base is removed. The configuration allows the caliper assembly (12) to be pivoted out, away from a brake disk (16) such that the friction pads (142, 242) may be easily replaced. The caliper assembly (12) includes a self-activating wear adjuster (172) that functions to maintain a constant brake gap (174) between an active friction pad (142) and the brake disk (16). The caliper assembly (12) also includes a wear indicator in the form of a spring (134) that provides additional force that is fed back to the user when the friction pad (142) is significantly worn.

In another embodiment of the invention, a keeper plate is coaxially secured to an output hub, with a friction disc fixedly secured therebetween. An input drive flange is rotatably mounted on the keeper plate. A separator disc extends the full diameter of the clutch assembly and has cup-shaped shields extending therefrom, serving as seals and heat dissipating members.

Abstract: A sealed vehicle wet disc brake has a brake housing and a piston housing which are fixedly interconnected and which receive a rotor. The two housings and rotor define an annular cavity which is sealed by appropriate rotary seals and in which is maintained a friction stack. The piston housing has a plurality of uniformly spaced piston bores therein, such bores being interconnected by an annular groove which circumferentially intersects with a circumferential surface of the piston housing. A pressure source of fluid communicates with the annular groove and the piston received within the bores. The annular groove is sealed by means of an "O" ring engaged therein from the circumferential surface and retained by a retaining ring. The intersection of the annular groove with the circumferential surface is tapered to accommodate compressive retention of the "O" ring.

The sprocket lies within a plane that intersets the clutch assembly between a pair of outboard bearings. Sprags are received within a cavity containing lubricant, such cavity being accessible through a bore in the output adapter. Additionally, the cavity is sealed by means of a seal which may be greased by external access.

Abstract: A torque limiter has an input flange connected to an output hub through a force generating subassembly which includes a pressure plate and a cover plate having a plurality of springs interposed therebetween. The cover plate is fixedly secured to the input hub in fixed spaced apart relationship. A friction material is secured to opposite faces of a circumferential flange which is integral with the output hub.

The force generating subassembly has a characteristic spring force associated therewith which is slightly increased when the assembly is completed. The total degradation of characteristic torque diminishes by only ten percent over the useful life of the clutch. The springs are color coded and visually verifiable.

In another embodiment, the discs are interposed between a pair of end plates fixed to an input hub. A bearing is interposed between one such end plate and an end plate of the output hub. The end plate of the output hub is fixedly secured to a stationary end friction plate.

Abstract: A multiple disc torque limiting clutch is presented. A stack of friction discs are splined to an output hub with a stack of separator discs interposed therebetween and keyed to a housing. Spring cup assemblies are positioned through openings in the separator discs to urge the separator discs into forceful contacting engagement with the friction discs. The spring cup assemblies include a compressed helical spring maintained within a cylindrical member and transmitting the spring force through the cylindrical member against the stack of separator and friction discs. The housing elements are of substantially unitary construction, with no relative movement capable therebetween. A wear indicator passes through the housing and indicates the degree of wear of the disc elements, while clearances between the interior of the clutch and the exterior are maintained at a minimum to provide a substantially explosion proof unit.
