Abstract: A brakeshoe having a backing plate formed with a seat recess opening at a face, is provided with a brakeshoe wear sensor held in place by a U-shaped spring clip. The clip is formed with a pair of legs extending generally parallel to each other and spaced so as to fit around the sensor and a front end extending between the legs and joining same together. The legs and front end fit wholly in the seat recess between the sensor and the backing plate and bear on the sensor and backing plate. A bent-out tab projects transversely from each of the legs and bears outside the recess on the face of the backing plate.

Abstract: The invention relates to a spring-clip (4) serving as a holder (1) for a brakeshoe wear sensor (2) in a brakeshoe backing plate (3) that is designed substantially in a U-shape and holds the wear sensor (2) in sections in a corresponding seat (5) of the brakeshoe backing plate (3) in such a manner that it cannot be lost in that parts of legs of the spring clip (4) rest on the seat (5) and on the wear sensor (2), in which the invention provides that at least one bent tab (6 and 7) projects from the spring clip (4) in sections and bear at least partially on the face of the brakeshoe backing plate (3) when the wear sensor (2) is inserted into the seat (5) by the spring clip (4).

Abstract: A brake-shoe wear sensor has a sensor element capable of being worn away for generating different electrical outputs in accordance with wear and at least one electrical wire connected to and extending outwardly away from the sensor element so that a controller can be connected to the sensor element via the wire. A one-piece housing has an inner end molded unitarily around and encapsulating the sensor element and an outer end spaced therefrom and molded unitarily around and encapsulating an outer end portion of the wire.

Abstract: Addition products of monoepoxides or diepoxides of mono- or polyunsaturated monocyclic or bicyclic hydrocarbons and dithiophosphoric acids, a process for the production of the adducts from the corresponding dithiophosphoric acids and epoxides and the use of the addition products as lubricant additives in lubricants based on mineral oils or native oils.
