10.1.2. A lay brake
The mechanical drive includes the lever 3 (fig. of the Detail of a drive of a lay brake see) which together with the returnable lever is mounted on an arm which fastens to a body floor. The returnable lever incorporates a finger with forward a cable 2 which other end there takes place through an aperture directing 9 back cables and on a carving tip навертывается a nut or a counternut. Moving of a forward cable goes a roller 8.
Through a groove directing 9 there passes an average part of the back cable which tension is regulated by a nut, навернутой on a carving tip of a forward cable. Between directing 9 and an adjusting nut the plug 10 is established распорная.
The ends of a back cable pass through a cover which one end fastens to a brake board, and another is established in a groove of an arm of a body. On the back ends of a cable there are tips, each of which incorporates to a hook of the lever 2 (fig. the Brake mechanism of a back wheel see) manual drive колодок. This lever a finger шарнирно fastens to brake колодке and the top part rests against a groove разжимной laths 9. The edge comes Into an opposite groove of a lath brake колодки.
When lift the lever 3 (fig. of the Detail of a drive of a lay brake see) there is a tension of forward and back cables. Thus the lever 2 (fig. the Brake mechanism of a back wheel see), turning on a finger, through распорную a lath 9 will press at first one колодку to a brake drum, and then, turning concerning a point of contact with распорной a lath and operating as двухплечий the lever, will press another колодку to a drum.
