An integrated brake spider and mounting bracket arrangement for a drum brake includes a brake spider with a spider mounting section, having openings through which fasteners may pass to secure the brake spider to an axle flange of a vehicle. The spider is also provided with a base section having an attachment surface for a bracket, and the bracket is secured by way of a metal fabrication process to the attachment surface of the base section and to actuator support structure adapted to support an actuator for the drum brake.

A friction assembly includes a dry-running disc pack with at least one lining disc and at least one counter disc, which are arranged one behind the other in an alternating manner in an axial direction of the disc pack, and which can be brought into frictional contact with one another, wherein the lining disc has at least one mass-pressed dry-running friction lining.

An anti-squeal shim includes at least a first metal layer and an elastomer layer that is bonded to the first metal layer. The at least first metal layer is configured as a first electrode for electrical connection to a resistance measuring system, and the elastomer layer is configured with structural spatial features that enable the elastomer layer to obtain a reduced thickness when subjected to a mechanical force in a direction perpendicular to the elastomer layer.

A method of assembling a clutch includes assembling a wedge chain by connecting a plurality of wedges together with links such that the wedges are movable relative to each other, and wrapping the wedge chain around an inner race. The method further includes connecting an end one of the links to an end one of the wedges to secure the chain to the inner race. The may also include installing the inner race into an outer race such that the wedge chain is radially disposed between the inner and outer races.

An electromechanical brake caliper comprising a caliper body comprising a housing containing a piston and a member for driving a mechanism for moving the piston. The driving member comprises a threaded body and a head comprising a face supported on a bottom of the housing, the supported face being provided with a non-friction coating.

Method and plant for manufacturing braking elements such as vehicle brake pads. The plant can comprise a first station that applies an adhesive to a first face of a metallic element; a second station that applies to the first face of the metallic element a block of friction material; a checking station that verifies the presence of the adhesive by detecting the gray level of a plurality of points of at least one zone of the first face; and a processing unit that compares the gray level detected for each point with a first threshold value, counts the number of points that have a gray level that satisfies a relationship (which is a function of the threshold value,) and compares such a value with a second threshold value to discard those metallic elements for which the percentage calculated does not correspond to the second threshold value.

A brake piston is described. The brake piston is configured for use in a disk brake system, the piston comprising: a body having an outside width perpendicular to a central axis; a footing disposed at a distal end of the piston; wherein the footing is configured to exert force on a brake pad during actuation of the disk brake system; the footing having a face configured to contact the brake pad, the face having a length and a width, wherein the length is longer than the outside width of the body, and the length is greater than the width.

A trunnion clutch system is provided for angularly positioning a payload. The system includes a trunnion and a clutch. The trunnion has an annular trunnion housing, a trunnion shaft that engages the payload, and an electromagnetic motor that turns the trunnion housing. The clutch has an annular clutch housing, a jack shaft, a coil of copper winding rings, a plurality of helical springs, an annular armature, and an annular platform. The clutch housing contains a channel. The jack shaft is disposed in the clutch housing and engages the trunnion. The coil of copper winding rings is disposed within the channel. The helical springs are disposed within an angularly distributed plurality of pockets within the clutch housing. The annular armature is disposed to be separate from the coil by a gap via the springs. The annular platform has an abrasive liner disposed adjacent the armature. Energizing the coil pulls the armature away from the liner, thereby disengaging the trunnion.

A disc brake includes a brake disc made of light metal and a brake pad. The brake disc includes a brake track having formed therein a plurality of depressions which are distributed over a surface of the brake track. The brake disc is formed from a hypereutectic aluminum silicon alloy, which has a silicon content of 13 to 21 wt. % and a maximum content of 0.3 wt. % of copper. The brake pad is configured to act on the brake disc and includes a NAO friction material.

A flexible unit absorbing misalignment and transmitting torque from a driving shaft to a driven shaft is provided between a pair of flanges individually provided on each of the driving shaft side and the driven shaft side, both the driving shaft and the driven shaft being hollow. A communication passage letting hollow regions of the driving shaft and the driven shaft communicate with each other to form a circulation space for a cooling fluid is provided in the flexible unit. The flow of the cooling fluid cooling a driving source driving and rotating the driving shaft from the inside is created in the circulation space. A seal portion seals between the circulation space and an outside space to prevent leakage of the cooling fluid from the circulation space to the outside space.
