Abstract

In an automobile the poser is produced at the engine and is then transmitted to the ttheele to obtain traction. The mechanical syaten oh ch connects the engine to the dries uhoels is called the TRANSMISSIONN LINE. It Includes all devices uhich aid. or regulate the floe of potter. Some of the functions of the transmission line are listed belon. LE One should be able to run the engine on no load. That is, one should be able to detach the driving tteela. 'This makes the starting of the engine easier. The CLUTCH and the GEAR BOX serve this function. !fir the engine ho been started one should be able to connect tt to the driving uheele , du lly and tiithout shook. Thin iwetion to fulfilled by the C1. To tintoln a ooncta t apoed the tractive effort at t tiheele should equal the resistance e to notion. Since the resin tame varies,- say, chile going along a plain road and up a gradient, one must have sons mean to change the tractive effort too.. For a gin barsepot or the torque and hence the tractive effort ai ll vary ai, th speed. Hence ue should be able to change the speed. It is also .noun that for maximun economy or povor tbe
