Abstract: An electrically actuated aircraft brake and method characterized by the use actuator modules which can be easily and quickly replaced as a unit. Quick and easy replacement of the actuator modules can be effected without disassembly of the overall brake and wheel assembly. Accordingly, brake manufacturing, repair costs, overhaul, parts stocking and maintenance costs and requirements are minimized and/or greatly simplified compared to integrated brake designs used in the prior art. Also, a malfunctioning actuator module on an aircraft can be replaced and preferably quickly enough to allow the aircraft to remain in scheduled service and/or with a minimum of downtime.

Abstract: The present invention concerns a disc brake mainly for road vehicles. The disc brake comprises a fixed caliper (1) straddling one or more brake discs (2), one or more thrust plates (6) and a number of brake pads (8). The brake discs (2) are received in a non-rotating but axially moveable relationship on a rotating hub (3). The brake pads (8) are guided axially moveable in the caliper (1) taking up the load of the brake pads (8).

Abstract: The present invention concerns a brake mechanism for a brake disc. The brake mechanism comprises a brake lever, a cross bar, one or more thrust plates and a closing plate. The brake mechanism is of a modular form comprising two or more units.

Abstract: A clutch brake for a heavy duty automotive clutch. The clutch brake consists of two semiannular halves each having first and second ends. Each half has one tab disposed inwardly which is adapted to connect with the keyways in the input shaft of the transmission. The two halves are pivotally connected at one end prior to installation. The second ends of the two halves are shaped such that they interlock, forming an annular assembly about the shaft.

Abstract: A vehicle brake arrangement includes a packet of alternating stator brake disks and rotor brake disks that are parallel and rotatable relative to each other. Each stator brake disk includes a support ring, support arms that are circumferentially distributed about, connected to, and protruding radially from an outer circumference of the support ring, and plate-shaped brake segments respectively removably secured in segment-shaped spaces between neighboring ones of the support arms by pivotable latch bars and spring-biased catches engaging recesses of the brake segments. Each brake segment includes a plate-shaped carrier, and a brake pad adhered onto at least one major surface of the carrier. The pads are made of sintered metal and the rotor brake disks are made of a ceramic or ceramic composite. Selective frictional contact between the sintered metal brake pads and the ceramic rotor brake disks provides effective braking friction, and the brake segments are easily exchangeable.

Abstract: Modified friction pad and friction-pad receptacle assembly for a brake/clutch module permitting greater ease in the friction pad's insertion into and withdrawal from the brake/clutch module. The improved ease is achieved by inverting the pad/receptacle coupling with respect to earlier designs, so that the pad is now held into the receptacle by clips at the distal end of the receptacle rather than the proximal end. That configuration in conjunction with finger-grip depressions near the proximal end of the pad allow the pad to be removed with one hand. This is due in part because of the way the clips of the present invention work so as to prevent the pad from falling out under the force of gravity but nevertheless yield to the slightly greater force applied by the operator desiring to remove the pad. Additionally, the present invention provides protection against wear for the torque-resistor pad guides by interposing the spring steel of the retaining clips between the pad assembly and these guides.

Abstract: A caliper of a disc brake assembly includes a housing with a cavity configured to receive a disc brake of a disc brake assembly. The cavity includes opposing recesses configured to nest first and second friction pad and plate assemblies on opposite sides of the disc. A drive within the caliper housing advances the first friction pad assembly into contact with the disc along an advancement axis. A retaining structure for the first friction pad and plate assembly includes a pad retention clip attached to the housing within the cavity, the pad retention clip defining an elongate track extending along the advancement axis. A retention tab on a plate of the first friction pad and plate assembly is configured to snap fit with the pad retention clip and to move along the advancement axis within the elongate track as the first friction pad and plate assembly is advanced along the advancement axis by the caliper drive.

Abstract: A boot-seal assembly (38) for sealing an actuation chamber (36) defined by a piston (34) being located in a bore (32) of a caliper (16) of a disc brake (10). The bore (32) has a first diameter (32a) separated from a second diameter (32b) by an annular shoulder (33), a step (37) adjacent the annular shoulder (33) and an annular groove (35) adjacent the step (37). The boot-seal assembly (38) include a square seal (50) and a boot (52), each of which surround the piston (34). The boot (52) has a molded cylindrical rubber body (54) with a metal insert (64). The metal insert (64) creates a radial outward projection (60) that extends from a first end (56) of the boot (52) and a radial inward lip (62) that extends from a second end (58) of the boot (52). The piston (34) is inserted in bore (32) and an initial force is applied to the second end (58) of the cylindrical body (54) to bring the first end (56) into contact with the seal (50) and position the seal (50) on the step (37).

Abstract: A disc brake assembly includes an improved pad holder for holding a brake pad in the brake assembly. The pad holder takes the form of a simple spring clip, preferably a wire form, that holds the rear surface of the pad tightly against the front surface of the piston or pistons of the associated caliper to prevent brake drag and brake rattle. The clip is simple and inexpensive to manufacture and can be easily installed without removing the disc or the caliper from the brake assembly. Indeed, the pad/pad holder subassembly can be removed from the brake assembly, without using any special tools, simply by imposing sufficient upward vertical retraction forces on the pad/pad holder subassembly to deflect the spring clip and to remove the pad holder from the pistons to which it is attached.
