摘要： A pad-and-spring assembly has a supporting plate supporting friction material. The supporting plate has a disc facing surface, a plate back, and facing thrust structure. The friction material has a radially inner edge, and a radially outer edge, radially opposite to the radially inner edge, and defining the outer radial dimension level of the friction material with its tangential extension on the disc facing surface. The disc facing surface has a free surface located radially inside with respect to the tangential extension of the radially outer edge of the friction and having a through opening edge delimiting a through opening. An elastic device of the assembly has a body having at least one connecting portion, connecting to the body of the brake caliper and a supporting portion, axially crossing the through opening to apply elastic biasing action directly in axial direction to the through opening edge.

摘要： A disc brake for a utility vehicle includes an application device, which is positioned in a receiving space of a brake caliper having a caliper housing and a lever dome arranged thereon. The application device has a pivotable brake lever, which is provided with at least one eccentric portion and a lever arm which adjoins the latter, the lever extending approximately parallel to the axis of rotation of the brake disc and projecting into the lever dome. Two brake plungers are mounted axially adjustably in a bridge and, during braking, lie against a brake pad. A readjustment device compensates for a wear-induced change in an air gap. A synchronizing device is connected functionally to the brake plungers and has a traction mechanism drive. The traction mechanism drive is arranged outside the lever dome, wherein strands of the traction mechanism drive are guided around a partial region of the lever dome.

摘要： Provided is an electric brake including: a brake mechanism configured to transmit, based on a braking request, a thrust force generated through drive of an electric motor to a piston configured to move brake pads to be pressed against a disc rotor; and an ECU for rear electric brake configured to control the drive of the electric motor, and to move, in a non-braking state, the piston to a predetermined clearance position at which a clearance between each of the brake pads and the disc rotor is a predetermined amount. The ECU for rear electric brake is configured to drive the electric motor so that a period from generation of the braking request to a start of the pressing of the disc rotor by the brake pads is a predetermined period regardless of a position of the piston at a time when the braking request is generated.

摘要： A disc brake for a commercial vehicle includes a pneumatic brake cylinder, a brake disc, a brake caliper, an application device and brake pads. The brake caliper engages over the brake disc and the application device, which can be actuated by the brake cylinder, is arranged in the brake caliper, by which the brake pads can be pressed against the brake disc on both sides during braking. An extendable and retractable piston rod of the brake cylinder is in engagement with the brake application device and the brake caliper is detachably fastened to the brake cylinder by a fastening device. The fastening device includes at least one screw with a screw head, a screw shank and an external thread formed on the screw shank and at least one bore formed in or on the brake cylinder with an internal thread, into which the screw shank is screwed with the external thread, wherein the screw head is locked on a counter surface of the brake caliper.

摘要： A disc brake for commercial vehicle includes a brake caliper and brake pads for clamping the brake disc. The brake caliper has a first inside space with an opening on a side facing the brake disc for receiving a clamping device, and the brake caliper has a second inside space for receiving the brake disc. The brake caliper and brake pads have advantages in terms of installation space and is lightweight and reduces production costs. The brake caliper includes clamping-side lugs and reaction-side lugs. The lugs on each side define a channel for receiving the brake pads for each side. The brake pads include supporting surfaces and bearing surfaces on their perimeter that correspond to the arrangement of the lugs. The lugs on the clamping side define an L-shape. The axial length of supporting surfaces of the clamping side brake pad is shorter than that of the clamping-side lugs.

摘要： The vehicular disc brake comprises a caliper bracket 3, a caliper body 6 attached to the caliper bracket 3, and friction pads 7, 7 disposed on both sides of a disc rotor 2, and the caliper body 6 comprises an action part 6a provided with cylinder holes 6f, 6g through which a large-diameter piston 10 and a small-diameter piston 11 are inserted, and a bridge part 6c extending across the outer periphery of the disc rotor 2. Thinned parts 6n, 6p are provided respectively in positions corresponding to the pistons 10, 11 in a disc-radially inner wall 6i of the bridge part 6c. The volume of the thinned part 6b corresponding to the large-diameter piston 10 on the disc turn-out side when the vehicle is moving forward is less than the volume of the thinned part 6p corresponding to the small-diameter piston 11 on the disc turn-in side.

摘要： The present disclosure relates to the positioning of a disc brake caliper mounted to a rigid bicycle fork. In one aspect, the disc brake caliper is attached to a portion in front of the fork and the front wheel axle, hence exposing the disc brake caliper to the maximum cooling potential of the airflow. Further, the disc brake caliper is positioned roughly horizontally in-line with the wheel axle to provide aerodynamic benefits for the trailing front wheel axle.

摘要： A brake device including a guide receiving area for connecting to a bearing component, forming a brake device bearing moveable in the direction of a first straight line. The brake device has a brake caliper with a first frictional surface and a first actuation surface, a pressing part being linearly guided along the first straight line relative to the brake caliper. The pressing part has a second frictional surface and a second actuation surface, and the brake device has a spreading element which interacts with the first actuation surface and the second actuation surface. The rotation of the spreading element changes the minimum distance between the frictional surfaces. A movement damping part coupled to the spreading element is designed to damp a translational movement of the spreading element relative to the bearing component in the guide receiving area parallel to the first straight line.

摘要： A detection device is described for detecting a force acting in a detection portion of a brake caliper and representative of a braking torque acting on the brake caliper when braking. The device is adapted to being mounted between the brake caliper detection portion and a corresponding hub holder by means of fixing and clamping means. When mounted and in the absence of forces acting on it, the detection device is shaped as a washer or plate extending mainly along a reference plane. The device may have a first functional element, a second functional element, a positioning element, and a sensing element.
