A variation of a standard automatic transmission toyota cvt transmissions employ an innovative design that really does not use standard gears. It s a bit like a snowmobile transmission.
In conventional transmissions a pre set number of gears limits the powertrain to a narrow operational range where fuel efficiency and performance are somewhat limited.
What is a cvt transmission toyota. Cvts are also lighter weight than traditional automatic transmissions. Toyota produces a special cvt that has a physical first gear like a conventional automatic then transitions seamlessly to a cvt after one upshift. Rather than have specified gears like a standard six speed automatic a continuously variable transmission possesses what can best be described as a single and variable universal gear.
Instead it uses 2 pulleys attached by a belt. But cvts are no longer a mere experiment by automakers looking for new. How does a toyota cvt transmission work.
One pulley attaches to the engine the other pulley to the transmission. A continuously variable transmission cvt doesn t utilize gears like a typical transmission. The flexibility of a cvt with suitable control may allow the engine to operate at a constant rpm while the vehicle moves at varying speeds.
Instead of fixed gears it uses a pair of variable width pulleys that are connected by a flexible belt. A cvt draws top engine power from a small engine which gives drivers quicker acceleration than standard automatic transmissions. Cvts were once derided as the shiftless rubber band transmission that made cars seem as if they were revving up forever.
A conventional automatic transmission. Just what is a continuously variable transmission cvt. This is why you may not even feel gear shifts with a toyota cvt transmission.
A cvt is a type of automatic transmission that delivers seamless acceleration without interruption for gear shifts. The continually variable transmission cvt has long been recognized by toyota engineers as one of the most powerful weapons in their battle for maximum fuel efficiency. There are a couple other types of cvts such as hydrostatic and magnetic that use fluids and magnets to transfer torque respectively but these are less common in cars and trucks.
A continuously variable transmission cvt is an automatic transmission that can change seamlessly through a continuous range of gear ratios this contrasts with other transmissions that provide a limited number of gear ratios in fixed steps. All you need to know about toyota s continuously variable transmission cvt in a single video. Because of their greater ability to control the engine speed range cvts produce fewer emissions.
This transmission is used on the corolla hatchback. With this system in place the transmission can work more efficiently providing positive results for drivers who opt for the continuously variable transmission. Toyota cvt transmissions will initially reach this engine speed quickly and work through a planetary gear system to keep the engine speed at this level regardless of vehicle speed.
