摘要： Disclosed is a drum brake device in which during a service brake application, a pair of brake shoes operates in a leading/trailing mode, and during a parking brake application, a parking brake mechanism operates to cause the brake shoes to operate in the duo servo mode. A first lever, an equalizer and a second lever, which make up the parking brake mechanism, are all assembled onto one of the brake shoes. The second lever includes an input portion, a lever contact portion and an equalizer contact portion. The input portion receives a force from a parking lever. The lever contact portion applies a turning force to the first lever. The equalizer contact portion applies a turning force to the equalizer. The second lever, when it is turned, turns the first lever and then the equalizer.

摘要： A drum brake device produces a stable braking force at a predetermined boosting ratio in response to a brake operation force input thereto, even if the friction characteristics of the interface of the brake drum and the brake shoe varies, without increasing the size of the wheel cylinder. The drum brake device includes an input detector that detects a hydraulic braking pressure output from a master cylinder, and produces a signal representative of the detected hydraulic braking pressure as an input force to the drum brake device; an output detector that detects an anchor reaction force generated at the time of braking and produces a signal representative of the detected anchor reaction force as an output force of the drum brake device; electromagnetic valves capable of controlling the supply of a hydraulic braking pressure supplied from the master cylinder to a wheel cylinder; and a control circuit that controls the operations of the electromagnetic valves in accordance with output signals of the input detector and the output detector so that the output force is limited to a force equal to or smaller than a force defined by a predetermined boosting ratio.

摘要： A joining link, a strut, and first and second expansion levers constitute an expansion and contraction device. At the time of the braking, the proximal end portion of both of the expansion levers are mutually pressed from the opposite sides by first and second pressing members constituting a driving device. The reaction due to the braking is offset by the joining link portion, whereby a large force is not applied to the back plate or the like.

摘要： A solid box-shape structure is constituted by fitting a torque transmitting ring 23 to a guide hole 17 on a guide plate 11 to pivotably hold a lining member 13 and fixing the guide plate 11 to a torque receive plate 3. A braking torque is directly transmitted to the guide plate 11 by the torque transmitting ring 23 by pressing the lining member 13 to a disc rotor by a first link plate 7 and a second link plate 5 arranged on an inner side of the box-shape structure. A solid structure and alleviation of processing accuracy are made to be compatible with each other by constituting transmission of a press force and transmission of a torque by independent members in this way.

摘要： Counter braking force acting on a secondary shoe is input to one end portion of a control lever supported with an anchor pin vertically provided on a backing plate in such a manner that the control lever is capable of swinging. An inner end portion in the radial direction of the control lever engages with a strut for pressing a primary shoe against a brake drum. Pressing force A with which the strut is pressing the primary shoe against the brake drum is drastically reduced when braking force, that is, the counter braking force increases and slightly reduced when the braking force, that is, the counter braking force decreases, whereby an increase or a decrease in the braking force is made automatically controllable.
