เกียร์แต่ละประเภทนั้นมีข้อดี-ข้อเสียแตกต่างกันไป ทั้งเรื่องความทนทาน ค่าบำรุงรักษา รวมถึงเรื่องการช่วยประหยัดน้ำมัน การจะเลือกซื้อรถยนต์สักคันหนึ่ง นอกจากจะดูเรื่องเครื่องยนต์แล้ว อย่าลืมตรวจสอบระบบเกียร์และทำความเข้าใจระบบการทำงานให้ดี เพื่อที่คุณจะได้ใช้รถอย่างเต็มประสิทธิภาพ และช่วยยืดอายุการใช้งานของเกียร์ด้วยนั่นเอง
HowStuffWorks The variable-diameter pulleys are the heart of the CVT. Each pulley is product of two twenty-diploma cones going through one another. A belt rides during the groove concerning The 2 cones.
Basically, torque ratios are realized once the v-belt rotates in the lower cross portion on the input pulleys and at the larger cross area from the output pulley.
Evans Variable Speed Countershaft A cone CVT differs the push ratio by going a wheel or belt along the axis of one or more conical rollers.
The distance concerning the middle with the pulleys to exactly where the belt would make Call from the groove is recognized as the pitch radius. Once the pulleys are much apart, the belt rides reduced plus the pitch radius decreases. If the pulleys are shut with each other, the belt rides better and the pitch radius raises. The ratio with the pitch radius to the driving pulley to your pitch radius about the driven pulley determines the equipment. HowStuffWorks When 1 pulley will increase its radius, one other decreases its radius to keep the belt tight. As the two pulleys modify their radii relative to one another, they develop an infinite quantity of gear ratios -- from low to superior and every thing in between.
This permits the motor to function at its most effective level, causing superior gas economic system and smoother acceleration.
Rather, it utilizes a pulley and belt system to change the equipment ratios repeatedly. This enables the engine to work at its best RPM assortment, resulting in enhanced gas effectiveness and smoother acceleration.
Some say You cannot educate an old Doggy new methods. However the continuously variable transmission (CVT), which Leonardo da Vinci conceptualized in excess of 500 many years back and is also now replacing planetary computerized transmissions in a few automobiles, is just one outdated Puppy that has certainly learned a handful of new methods.
Consumers inform team the care is everyday living-transforming; several former purchasers get steps to provide folks to CVT so that each of these could get the treatment they been given.
The laman utama most typical style of CVT takes advantage of a V-belt which operates concerning two variable-diameter pulleys.[one] The pulleys encompass two cone-shaped halves that transfer collectively and aside. The V-belt operates between these two halves, Therefore the powerful diameter of your pulley is depending on the distance in between The 2 halves of your pulley.
The belt in most CVT devices is actually a heavy responsibility “V-belt” which can be V-shaped in cross part. They're crafted from rubber components strengthened with Kevlar and other elements to enhance sturdiness.
Equally of these Positive aspects are why CVT gearboxes are commonly Utilized in hybrid vehicles. The smoothness of the CVT pairs nicely Along with the smoothness of an electric motor, when the two Blend for superb gas economic climate.
The pliability of the CVT with acceptable control may allow the motor to work at a relentless angular velocity though the auto moves at different speeds.
Positively Infinitely Variable (PIV) chain drives are distinctive in that the chain positively interlocks Together with the conical pulleys. This is reached by having a stack of many smaller rectangular plates in Every chain backlink that can slide independently from aspect-to-facet. The plates might be very slender, about a millimeter thick. The conical pulleys have radial grooves. A groove on one particular facet from the pulley is fulfilled which has a ridge on the other aspect and Hence the sliding plates are pushed forwards and backwards to conform to the sample, efficiently forming tooth of the proper pitch when squeezed between the pulleys.
