In this article, the company ConSys<\/strong> will consider the characteristics of the remote control cables used on buses, special. machinery, combines and tractors, as well as trucks. Sometimes the quality of the remote control cables is such that after a short life of the vehicle it is necessary to adjust it. But the owners do not always know about this and bring the control cable to failure. Sometimes the design of the cables does not allow its adjustment – this is stated here<\/a><\/p>\n Each control cable has a characteristic called \u201cLOSS OF STROKE\u201d<\/strong> or in English sources – BACKLASH<\/strong> factors of mechanical control cables. The loss of stroke is measured as the difference between the magnitude of the movement of the cable under pulling and pushing loads, while the outgoing end of the cable remains stationary:<\/p>\n Loss of control cable travel<\/p><\/div>\n Source: http:\/\/machinedesign.com\/article\/accounting-for-lost-motion-0111<\/span><\/p>\n This phenomenon is associated with the presence of gaps between the core and the sheath of the control cable.<\/p>\n Theoretically, the loss of stroke should tend to zero, but in practice, some loss of stroke should be allowed, otherwise the remote control cable will be \u201chard to walk\u201d or remain pinched. Loss of travel causes include the frictional properties of core and cladding materials, the presence of a curved path, and sometimes the length of the cable. Also, the reasons may be due to thermal expansion, etc.<\/p>\n For each cable manufacturer, most popular in the CIS, these data are given below:<\/p>\n 1)\u00a0\u00a0\u00a0\u00a0 For Kongsberg Automotive<\/b> (KA) <\/strong>MORSECONTROLS<\/b><\/em> (http:\/\/www.teleflex.com.au\/products.php?pID=2<\/span>):<\/p>\n Cable series<\/b><\/p>\n<\/td>\n Data shown is only for 360 degrees (Maximum Backlash for 360 degrees)<\/b><\/p>\n<\/td>\n<\/tr>\n 30<\/p>\n<\/td>\n .120inches (3.1 mm)<\/p>\n<\/td>\n<\/tr>\n 40<\/p>\n<\/td>\n .150inches (3.8 mm)<\/p>\n<\/td>\n<\/tr>\n 60<\/p>\n<\/td>\n .180inches (4.6 mm)<\/p>\n<\/td>\n<\/tr>\n 80<\/p>\n<\/td>\n .230inches (5.8 mm)<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n <\/p>\n 2)\u00a0 \u00a0 \u00a0For Cablecraft Motion Controls<\/b><\/em> (http:\/\/www.instrumentsales.com\/assets\/Push-Pull_Standard_Industrial.pdfPull_Standard_Industrial.pdf<\/span>)<\/p>\n
\nThe most important performance parameter is the loss of cable travel (play = Backlash).
\nDuring operation, the remote control cable inevitably lengthens (stretches), which leads to a fuzzy or even difficult inclusion of gears.<\/p>\n<\/a>
