    Abstract: The reverse input cutoff clutch includes: a pressed member having a pressed surface around the inner peripheral surface; an input member coaxially arranged with the pressed surface and having an input-side engaging portion arranged on the radially inner side of the pressed surface; an output member coaxially arranged with the pressed surface and having an output-side engaging portion arranged further on the radially inner side than the input-side engaging portion; and an engaging element arranged so as to be movable in a first direction as a direction toward or away from the pressed surface on the radially inner side of the pressed surface. The engaging element has a main engaging element body having a pressing surface and a pivot-support shaft, and a link member. The link member has a first end portion pivotally linked to the pivot-support shaft, and a second end portion pivotally linked to the input-side engaging portion.

    Abstract: A triboelectric generation apparatus based on a friction brake and a friction brake provide a simple structure with high reliability, a stable circuit, and high energy recovery efficiency. The triboelectric generation apparatus includes two sensing electrodes arranged in a first friction component of the friction brake. When the first friction component is in frictional contact with a second friction component, induced electric charges are generated on the two sensing electrodes. The induced electric charges are different. An electric charge collection circuit is connected to the sensing electrodes and is configured to store the induced electric charges. Storing the induced electric charges allows for the recovery of energy using a simple structure with high reliability.

    Abstract: A brake pad retractor system, comprising, a torsional mount and an adjustable torsion arm having an angular relation with the torsional mount, wherein the torsion arm is sprung responsively to at least some movement of a brake pad and the torsional mount being operative such that upon movement of a brake pad by a first distance, the torsion arm is sprung and communicates an action upon the brake pad through a contact between the torsion arm and the brake pad, the communicated action sufficient to positively retract the brake pad upon release of the brake system, the torsional mount further operative such that upon further movement of a brake pad beyond the first distance the angular relation between the torsion arm and the torsional mount is adjusted responsively to the further movement. Further aspects include a novel a brake caliper and method.

    Abstract: An automatic slack adjuster includes a lever configured to be coupled to a push rod of a brake actuator, and to pivot about a rotational axis when actuated by the push rod, the rotational axis having a predetermined fixed location relative to the vehicle. A stroke indicator label is arranged on the lever and configured to designate, for the automatic slack adjuster, a predetermined zero stroke position, a working stroke range, and an overstroke range. A stroke indicator element is configured to visualize the current stroke level of the automatic slack adjuster on the indicator label by way of relative movement between the stroke indicator element and the stroke indicator label in response to pivotal movement of the lever. A mounting bracket of a mounting interface can be adjusted relative to the rotational axis for correctly installing the stroke indicator element.
