Extending in opposite directions from their pivots (F16D51/20)

Brake spider for drum brake and brum brake // 2634854
FIELD: automotive engineering.SUBSTANCE: brake spider contains the mounting section for installation the spider on the vehicle frame, and the anchor finger support part, extending from the mounting section. The mounting part defines the opening, centered around the first axis and configured to receive the semi-axle of the vehicle, passing through the mentioned opening along the first axis. The support part of the anchor finger includes the finger receiving section, defining the opening centered about the second axis and configured to receive the mentioned anchor finger, passing through the hole along the second axis. The support part of the anchor finger additionally includes the bracket support sections, extending axially from the opposite sides of the finger receiving section. The bracket support sections face each other and move away from each other as it approach to the spider mounting part.EFFECT: increase of the device rigidity and strength.30 cl, 12 dwg

Brake shoe and braking unit // 2628555
FIELD: automotive industry.SUBSTANCE: brake shoe contains the arc-shaped base, having the outer side in the radial direction to install the brake pad and the inner side in the radial direction, opposite to the outer side. Several loops are also formed at the base near its first end. The loops are aligned along the axis and located at the distance from each other along this axis. Each loop is configured in such a way, that it is possible to insert the fastening pin inside it, by means of which the brake shoe can be attached to the brake mounting support with ability to turn. The fastening pin is fixed in the first and the second loops to prevent its movement relative to these loops. The brake unit contains the mounting support, the brake shoes and the drive actuator. The actuator movement causes the movement of the first and the second brake shoes between the engagement position with the brakes working surface and the position, when it does not contact the working surface.EFFECT: stability of braking and steering dynamics.20 cl, 6 dwg

Friction pad, brake shoe and drum brake assembly // 2600143
FIELD: motor vehicle industry.SUBSTANCE: group of inventions relates to automotive industry, in particular, to drum brakes friction pads. Friction pad has upper surface and two beveled edges turned in opposite directions, which do not pass along friction pad entire thickness. Each beveled edge has arc length exceeding one inch, and passes at angle ranging from 10 to 25 relative to upper surface tangent line at its intersection point with beveled edge line. Brake shoe, passing along arc, has at least one friction pad attached to brake shoe outer surface. Drum brake assembly to brake vehicle has drum cylindrical surface, in which two brake shoes are accommodating, passing along arc and having outer surfaces and at least one friction pad.EFFECT: decreased noise and vibrations occurring during braking.20 cl, 4 dwg
