เกียร์แต่ละประเภทนั้นมีข้อดี-ข้อเสียแตกต่างกันไป ทั้งเรื่องความทนทาน ค่าบำรุงรักษา รวมถึงเรื่องการช่วยประหยัดน้ำมัน การจะเลือกซื้อรถยนต์สักคันหนึ่ง นอกจากจะดูเรื่องเครื่องยนต์แล้ว อย่าลืมตรวจสอบระบบเกียร์และทำความเข้าใจระบบการทำงานให้ดี เพื่อที่คุณจะได้ใช้รถอย่างเต็มประสิทธิภาพ และช่วยยืดอายุการใช้งานของเกียร์ด้วยนั่นเอง
Leakage of transmission fluid is another challenge with CVTs. Issues will often be indicated by pink, sweet-smelling fluid. Low fluid ranges can injury parts, bringing about preset level challenges and delayed movement.
Put simply, torque ratios are realized once the v-belt rotates within the reduced cross section on the input pulleys and with the greater cross area of the output pulley.
When energy is a lot more critical than financial system, the ratio with the CVT is often modified to allow the motor to show at the RPM at which it creates the best electric power.
The space involving the center from the pulleys to where the belt will make Get hold of while in the groove is called the pitch radius. In the event the pulleys are significantly apart, the belt rides lower as well as pitch radius decreases. Once the pulleys are close together, the belt rides bigger as well as the pitch radius improves. The ratio from the pitch radius to the driving pulley to the pitch radius within the pushed pulley determines the equipment. HowStuffWorks When 1 pulley improves its radius, the opposite decreases its radius to help keep the belt limited. As the two pulleys improve their radii relative to one another, they create an infinite amount of gear ratios -- from small to significant and almost everything in between.
A modify in equipment ratios is obtained through the variation of distance amongst the pulleys as well as their variable diameter.
The push ratio may be established to infinity (i.e. a stationary output disk) by moving the output disk to the rujuk sini center of your input disk. The output way may also be reversed by going the output disk previous the center with the input disk. The transmission on early Plymouth locomotives labored using this method, whilst on tractors applying friction disks, the variety of reverse speeds was usually confined.[28]
Just so you recognize, we may well get a Fee or other compensation in the backlinks on this Internet site - examine why you should trust us.
In addition they require challenging shifting. It’s called a CVT as it can alter the dimension of its pulleys. This is certainly carried out to match different speeds. This will help to transfer rotational power between the shafts.
Light-weight and Compact: A CVT is usually lighter plus much more compact than a standard automated transmission. This may end up in a lighter Total motor vehicle fat, which could increase dealing with and efficiency.
As The 2 cones shift independently, that means there aren't any established equipment ratios as you would discover in a standard car or guide, so a CVT is, in influence, only one-velocity device with infinite equipment ratios readily available.
Both of those of these Advantages are why CVT gearboxes are commonly Utilized in hybrid autos. The smoothness of a CVT pairs properly Together with the smoothness of An electrical motor, even though The 2 Merge for exceptional gas economic system.
Mix harvesters made use of variable belt drives as early as being the 1950s. Lots of modest tractors and self-propelled mowers for house and back garden use basic rubber belt CVTs. Hydrostatic CVTs are more prevalent around the larger sized units.
เครื่องยนต์สามารถทำงานได้อย่างเต็มประสิทธิภาพเสมอ และสามารถปรับระดับเกียร์ได้อย่างไม่จำกัด
