Some Common Gear Applications in your Automobile.
by Garima Modi
Gears are everywhere and are used for a number of different applications ranging from your washing machine to multi-million dollar industrial machinery. Our cars would not be able to get us from place to place without the technology of gears. Gears are so important because they provide something called gear reduction. Gear reduction allows enough torque to be applied in instances where it’s needed despite sufficient power.One common automotive application is the ring and pinion gear differential within rear-wheel-drive cars and trucks. Within the world of gears, the ring and pinion gears are a type of bevel gear. A bevel gear is used because it reassigns the power from the driveshaft 90 degrees, which is necessary to transfer power to the axle shafts that are connected to the rear wheels. A special type of bevel gear used for this application has hypoid teeth instead of straight teeth. Hypoid teeth are curved and allow for a gradual “meshing” of the gears that makes for much smoother and quieter operation than bevel gears with straight teeth. Without hypoid gears, our cars would be very loud and “jerky” in regard to the transmission of power. The use of rack
