What components make up the transmission?
The main components of an automatic transmission include the torque converter, planetary gearset, pump, clutches, bands, sensors, valve body, and last but not least is the transmission fluid, otherwise known as ATF.
What material are transmission gears made from?
Gears are made of variety of materials depending on the requirement of the machine. They are made of plastic, steel, wood, cast iron, aluminum, brass, powdered metal, magnetic alloys and many others. The gear designer and user face a myriad of choices.
Which material is best for gear?
Thermoplastics are the best choice for gears where weight is the most important criteria. Gears made from plastics can be machined like metallic gears; however, some thermoplastics are better suited for manufacturing via injection molding. One of the most common injection molded thermoplastic is acetal.
Which gear ratio allows for a hunting tooth?
Repeating tooth frequency can often be found by simply counting against a watch second hand. Common factor = 1 It is always best to have a hunting tooth combination, that is every bull gear tooth eventually mates with every pinion tooth.
Why are pinions harder than gears?
This is because the smaller pinion turns many more times than the ring gear, and logic dictates that the pinion will probably wear out faster than the ring gear. To counter this affect, the surface hardness of the pinion is usually made harder than the ring gear.
What is the S in automatic transmission?
“S” is for sport. If you’re driving on twisty country roads and want to keep the RPM up as you wind through corners, the “S” position is where you want to be. In “S”, the transmission holds lower gears longer for more power as you come out of the curves.
