The invention relates to a motor vehicle actuator, in particular a brake actuator, comprising a housing (3) which consists of a housing container (1) and a housing cover (2) designed as a base support, and in which an electric motor (4) and a transmission (6) coupled to the electric motor via a torque transmitting device (5) are arranged. A retaining frame which can be arranged on the housing cover (2) is provided in order to arrange the electric motor (4) within the housing (3). The invention is characterized in that the holding frame (7) is designed as a damping and/or spring device.

A balance module 10 for a clutch comprises a first annular piston part 11, a second annular piston part 12, which is arranged opposite the first piston part 11 in the axial direction and spaced therefrom, at least three spring elements 13 operating in the axial direction, which are arranged axially between the first 11 and the second piston part 12, and a sealing element 14 with at least one radially outwardly directed sealing lip 15, which is attached on the first piston part 11. The spring elements 13, the first 11 and the second piston part 12 are connected to one another in a loss-proof manner, in order to form an integral module 10.

An improved expanding friction disk for use in a clutch of a power transmission system. The improved expanding friction disk accommodates multiple clutch pack configurations including clutch packs utilizing novel improved friction disks, is compatible with wear liners and operates with reduced friction including a reduced difference between the static and dynamic coefficients of friction in the ramp mechanism.

A system is provided for suppressing undesired brake pad motion during brake application, and for installing and removing brake pads utilizing the inventive arrangements. The brake pads and a carrier mount having complementary surface features that retain the brake pad when the brake pad is in its installed position, and a brake pad biasing structure that biases the brake pad in the radially outward direction to bias the contact faces of the mount horn and the brake pad against one another to suppress brake pad kick and vibration and related wear and component fatigue. The radially-outward biasing force may be applied by a spring-loaded plunger located within a bore of a mount horn of the brake pad carrier against a radially-inner surface of a portion of the brake pad extending laterally over the mount horn.

A brake disc for an aircraft wheel brake including: a temperature sensing device comprising a surface acoustic wave (SAW) sensor element and a sensor antenna, wherein the temperature sensing device is attached to the brake disc by means of a ceramic adhesive and one or more ceramic bolts. A method of attaching a temperature sensing device to a brake disc of an aircraft wheel brake.

A tool for installation and removal of flexible couplings includes a first plate having a hinge member rigidly extending from the first plate and a shaft engaging feature defined in the first plate opposite the hinge member thereof. A second plate has a hinge member rigidly extending from the second plate and a shaft engaging feature defined in the second plate opposite the hinge member thereof. The hinge members of first and second plates are hinged together for rotation of the first and second plates about a hinge axis to actuate the shaft engaging features toward and away from one another.

A method for manufacturing a disc brake, the disc brake having a brake caliper and a brake actuation mechanism being supported in it, in which the brake actuation mechanism includes an amplification mechanism for introducing a clamping force, an adjustment device for compensation of lining wear with a torque clutch, a thrust element for transmitting the clamping force onto a brake disc and a reset device, which components are arranged around a rod, in which the torque clutch is formed as a roller-ramp-mechanism. A spring force can act onto the torque clutch by means of the reset device thereby forming a torque limit.

A drive assembly for a motor vehicle clutch is provided. The drive assembly includes a damper including a plurality of springs, a first cover plate and second cover plate. The first and second cover plates support the springs therebetween and the second cover plate includes an outer portion extending radially outside of the first cover plate. The drive assembly further includes a subassembly including at least one clutch facing and at least one support segment supporting the at least one clutch facing. The at least one support segment includes an outer radial portion fixed to the at least one clutch facing and an inner radial portion connected to the outer portion of the second cover plate to connect the subassembly to the damper.

A shaft-hub connection with a shaft that includes a section with external splines, and a hub that includes internal. The hub with its internal splines is assembled in a positively joined manner with play on the section of the shaft including the external splines. The shaft in the section includes the external splines has a recess regularly inside of the external splines, in which a clamping body is inserted neutralizing the play between shaft and hub.

A disk brake allowing a connector terminal (255) and a joining terminal (256) to be easily positioned in a width direction thereof and a direction toward an opening portion of a housing, because the joining terminal fixed to one end of a harness includes individual protruding portions (265) and a pair of biasing portions (264). Further, due to each of the biasing portions, the connector terminal and the joining terminal can be brought into close contact with each other. Further, due to the protruding portions of the joining terminal, an end (258A) of the connector terminal and an end (268A) of a contact surface portion (263) can be brought into alignment with each other, which facilitates formation of such a welded portion (266) that extends over the respective ends, and thus achieves a secure connection between the connector terminal and the joining terminal
