The Single Best Strategy To Use For cvt
อาจให้ความรู้สึกในการควบคุมการขับขี่ที่ดีกว่าด้วยการปรับเปลี่ยนเกียร์ขึ้นลงเป็นสเต็ป
It is the kind of shaft which is held parallel for the enter shaft in a very continually variable transmission, exact same as enter shaft Furthermore, it has splines more than its cross-section and is also mounted upon by output pulleys.
In a sequence-based CVT, various chain aspects are organized alongside a number of steel bands layered above one another, Every single of and that is slim ample to simply bend. When A part of the belt is wrapped all around a pulley, the edges of the elements type a conical floor.[four][five] Within the stack of bands, Every single band corresponds to a rather different push ratio, and thus the bands slide about each other and wish sufficient lubrication.
ความกว้างของพูลเลย์จะเปลี่ยนไปตามกำลังที่รถต้องการ เมื่อพูลเลย์ข้างหนึ่งใหญ่ขึ้น พูลเลย์อีกข้างจะเล็กลง และเนื่องจากพูลเลย์กับสายพานมีความยืดหยุ่นจึงสามารถให้อัตราทดเกียร์ที่ไม่จำกัด ต่างจากเกียร์ออโต้ที่มีเกียร์อย่างจำกัดนั่นเอง
A CVT gearbox has a comparatively straightforward arrangement of two cone-shaped pulleys which has a V-formed drive belt connecting them. One pulley is hooked up for the engine, though the opposite is joined towards the wheels.
It’s alright to choose possibly of The 2, nonetheless it is determined by what you would like in a car. For just a each day driver much like the Toyota Vios or Mitsubishi Mirage, the CVT is hard to conquer with its blend of smooth operation and sterling gasoline financial system.
The key pulley receives larger as it turns, which makes a specific gear ratio. In such cases, a single turn with the driving pulley helps make the pushed pulley change 4 occasions.
With out a subpoena, voluntary compliance around the part of your respective World wide web Service Service provider, or further records from the third party, information and facts stored or retrieved for this purpose by yourself can't ordinarily be accustomed to recognize you.
It is actually the kind of conical pulley that is mounted around the enter shaft and also have inner splines meshed with the shaft splines in this kind of style that it could transfer (too and fro) and rotates Along with the input shaft. the as well and fro instant of the shaft above the input shaft enable it to be doable to shift equipment ratios.
This arrangement minimizes the load about the hydrostatic percentage of the transmission when within the forward course by transmitting a significant portion in the torque as a result of a lot more order sekarang economical set gears.[21]
The belt in the majority of CVT methods can be a major obligation “V-belt” and that is V-shaped in cross portion. They can be made of rubber elements strengthened with Kevlar and other components to reinforce longevity.
풀리 지름만 조절하면 넓은 기어비 범위를 구현할 수 있고 기어 단수의 제한을 받지 않으므로 엔진 회전수를 비교적 정밀하게 제어할 수 있어 연비도 좋다.
ผู้ขับขี่บางรายพบกับการสูญเสียความเร่งอย่างกะทันหัน และระบบเกียร์ที่มีความร้อนสูงเกินไป อาจพบการกระตุก ลื่น และสั่น เนื่องจากสายพานอาจสึกหรอหรือยืดตัวมากเกินไปได้
Positively Infinitely Variable (PIV) chain drives are distinct in the chain positively interlocks Along with the conical pulleys. This really is reached by aquiring a stack of numerous little rectangular plates in Every single chain backlink that can slide independently from side-to-aspect. The plates could possibly be rather slender, about a millimeter thick. The conical pulleys have radial grooves. A groove on a single aspect with the pulley is achieved with a ridge on the other side and Therefore the sliding plates are pushed backwards and forwards to conform on the sample, properly forming enamel of the right pitch when squeezed involving the pulleys.
