TRANSMISSION GEAR SELECTION FOR MANUAL

摘要

abstract; the application for utility model "gear selection mechanism for the manual"; The present invention relates to mechanical engineering products, more precisely, to a gear box of the vehicle control devices.; Problem to be solved is to improve the reliability of the design gear selection mechanism, as well as expanding the range of manual gearboxes for automation.; The technical result consists in the use of the four-pneumatic design with a clamp-type spring initial position for gear selection mechanism and the use of microswitches for detecting the position of the cylinder rod.; Technical result achieved using the gear selection mechanism for a manual, which consists of a pneumatic cylinder managed normally closed pneumatic solenoid valves. cylinder rod is connected with the working chamber of the gearshift lever, and the cylinder is provided with a controllable stop for its rod axis. Emphasis rod is designed as a two-position piston.; The difference lies in the fact that the stop is disposed on the cylinder rod in one pneumatic cylinder. one longitudinal groove formed on the rod of the cylinder, which includes a retainer mounted on the housing. This eliminates the twist lock cylinder rod around its axis. four transverse groove which when moving the cylinder rod act accordingly on four microswitch mounted on the spring housing is also formed on the rod. the spring housing is coaxial air cylinder.
