It's a safety system so the car doesn't start on its own.
in this case, it is called a neutrelizer because it “neutralizes” the torque of an engine by generating a negative voltage at the synchroniser points. this prevents over-speed and damage to the engine from excessive torque due to attach from another vehicle or branch sticking onto car gears. a synchroniser is a part of a differential which rotates with one wheel on top of axle shafts – there can be more than one synchronizer in case of multiple-gearbox trucks, but only one integrated into axle shafts on powered axles for cars.
what is the function of the synchroniser?
the synchroniser's function is to work with the computer. it is based on a hardware compiler for code that doesn't need low level access to the system memory which makes it more efficient if speed of execution results in increased productivity.
in addition, it aids in maintaining security by controlling access to devices and data. these security features make the synchroniser a safe choice for enterprise use.
most commonly, you'll hear stories about how people who had an unsuccessful date with someone else would sometimes go on a friendly date together instead of going home alone – this was called friendship “syncing”.
why is gearbox necessary in automobile?
the gears are necessary to convert the rotational energy of the engine's crankshaft to torque at the wheels so that rotational force doesn't have to be applied by friction only.
it is because, without gearboxes, energy would have to be transmitted from out engine via two mechanical gears back and forth through a flexible material like rubber or nylon. this would require constant pressure down both axles which would need enough braking capacity for any load desired no matter how high upward speed was achieved. rubber or nylon could become very hot or slippery causing all sorts of difficulties in operation since they would quickly wear out. engineers chose steel as pulleys are usually made from steel with teeth on it side facing away from what is being driven because
why is synchronizer required in the transmission system?
transmission systems would be only as good as the weakest link, if there were no synchronizer. it separates high speeds from lower speeds and removes “noise” from current to give a clean transmission.
the synchronizer helps the entire system to work smoothly without any jerky starts or stops so that even though semi-synchronous converters will have a period of not being connected during a switching cycle, it will do so at predictable time intervals so that they aren't constantly disconnected mixed with other components on the system making for a rough ride. without it your car would be really hard to start because if you're out of sync then some pistons might stop but then restart before others causing them all to ping about and break
what are synchros in a car?
synchros are gears that allow one or more individual component shafts respectively to work independently.
for example, in an automatic transmission, the synchro provides for full-gearshift capability for each drive gear set with automatic shift features. a synchronized torque converter supplies power up the slippery slope by changing its lockup range and a low starting current through a staged sequence of solenoid valves creates an initial clutch slip which synchronizes the engine speed and planet carrier speed before settling into locked drum capability.
