Nissan then switched from toroidal to pulley-primarily based CVTs in 2003.[44] The version of the CVT used With all the VQ35DE engine within the fourth-generation Nissan Altima is claimed to get effective at transmitting bigger torque loads than other belt CVTs.[forty five]
Adhering to your upkeep agenda can drastically increase the daily life of your respective CVT and assure its general performance continues to be consistent.
Keeping a CVT transmission is important for its longevity and effectiveness. Key upkeep tasks contain:
Result in: Rattling noises can take place because of loose or broken areas throughout the transmission or even the encompassing elements. This might be one thing as simple as a unfastened heat protect or a far more critical difficulty throughout the CVT.

Continue to in development, the magnetic CVT transmits torque using a non-contact magnetic coupling.[30] The design takes advantage of two rings of long term magnets having a ring of metal pole pieces in between them to create a planetary gearset applying magnets.
The 1965 Wheel Horse 875 and 1075 backyard garden tractors ended up the primary these types of vehicles to generally be equipped with a hydrostatic CVT. The design utilized a variable-displacement swash-plate pump and glued-displacement equipment-kind hydraulic motor merged into one compact offer. Reverse ratios have been attained by reversing the circulation of the pump through about-centering on the swashplate.
Often called the Wankel engine, this unconventional powerplant has long been at the center of a few of the most enjoyable and memorable autos in automotive history.
