A retainer for a segmented annular heat shield of a wheel includes a first end, a second end opposite the first end, and a body extending between the first end and the second end. Both the first end and the second end are configured to be coupled to at least one of the wheel and a torque bar. Further, the body includes opposing longitudinal sides configured to respectively engage and secure a respective heat shield segment of the segmented annular heat shield. Also, the retainer includes a cover coupled to and extending over at least the body, with an air gap being defined between the body and the cover.

This disc brake includes a first shim that has a first flat plate portion and claw portions curved from an outer edge side of the first flat plate portion and attached to an outer circumferential surface of a rear plate; and a second shim that has a second flat plate portion disposed in a manner of being sandwiched between the first flat plate portion and the rear plate, and a bent portion curved from an outer edge side of the second flat plate portion to the first flat plate portion side. Relative movement of the second shim with respect to the first shim on a plane parallel to the second flat plate portion is restricted. A leading end portion of the bent portion of the second shim is disposed within a projection plane of a largest flat surface portion of the rear plate in a disc axial direction.

A brake system comprising a brake disc, a wheel hub connected to the brake disc, and a bearing assembly mounted around the wheel hub, the brake system further comprising: a first electric circuit embedded inside the brake disc; a second electric circuit embedded inside the wheel hub and electrically connected with the first electric circuit; and a third electric circuit embedded inside the bearing assembly and electrically connected with the second electric circuit, wherein when an electric current flows to the first electric circuit through the second and third electric circuits, the first electric circuit generates heat for applying to the brake disc.

A wheel and brake assembly comprising: a stator; a rotating assembly mounted around and rotatable relative to the stator about an axis A; a torque tube in fixed engagement with the stator; a stack of brake disks mounted about the torque tube, the stack of brake disks comprising alternate rotor disks and stator disks, the stator disks attached to the torque tube and the rotor disks attached to the rotating assembly; a brake actuator configured to, in response to a brake command, apply a pressing force on the stack of brake disks to cause frictional engagement between the rotor disks and the stator disks such that the stator disks prevent the rotor disks and, hence the rotating assembly, from rotating relative to the torque tube.

A brake system for an electric wheel drive unit has a housing that can be attached securely to the vehicle frame. The housing has a flange region and a shaft-like wheel carrier region secured to the flange region. A first brake component is connected to the housing and includes a first support part attached directly on a radial outer side of the wheel carrier region and a first brake disc element rotationally fixed to the first support part. A second brake component is rotatably mounted relative to the housing and has a second support part and a second brake disc element rotationally fixed to the second support part. A hydraulic actuation device is provided with one or more pressure pistons arranged. A sliding element is provided for moveably coupling the pressure pistons with one of the brake disc elements.

A grommet for a heat shield may comprise a radially outward surface and a radially inward surface opposite the radially outward surface. A plug opening may be formed in the radially outward surface. An exterior radial surface may extend from the radially outward surface to the radially inward surface. A shield groove may be formed in the exterior radial surface. An inward protrusion may extend radially inward from the radially inward surface.

A heat shield assembly for a braked aircraft wheel is provided. The heat sheild assembly includes a heat shield and at least one spacer having both a main body projecting from an outwardly-facing surface of the heat shield and a clamping element of generally cylindrical shape projecting from the body and passing perpendicularly through an opening in the heat shield. The clamping element can include an enlarged free end so as to co-operate with the body to form an annular groove engaged with the opening in the heat shield.

A disc brake device includes a pad, a caliper including a cylinder, a piston, and a rotary-to-linear motion conversion mechanism. The piston is divided into two parts that are a piston main body and a piston cap. The rotary-to-linear motion conversion mechanism includes a rotary member and a linear motion member. A unidirectional rotation regulating portion between the piston main body and the piston cap is configured to regulate relative rotation of the piston main body in a forward rotation direction with respect to the piston cap when the rotary member is driven to rotate in the forward rotation direction, and to allow relative rotation of the piston main body in a reverse rotation direction with respect to the piston cap when the rotary member is driven to rotate in the reverse rotation direction.

A system including a magnet configured to move in response to a movement of a wear pin indicator of a brake assembly of a vehicle. A sensor is configured to generate position data corresponding to the magnet. The position data is indicative of a position and/or movement of the wear pin indicator. The system includes a thermoelectric generator configured to generate an electrical signal based on an operation of the brake assembly. The thermoelectric generator is configured to deliver at least a portion of the electrical signal to the sensor. The system includes a mounting bracket configured to mechanically couple a sensor housing to an actuator housing of the brake assembly. The mounting bracket is configured to provide heat to the thermoelectric generator when the mounting bracket mechanically couples the sensor housing and the actuator housing.
