เกียร์แต่ละประเภทนั้นมีข้อดี-ข้อเสียแตกต่างกันไป ทั้งเรื่องความทนทาน ค่าบำรุงรักษา รวมถึงเรื่องการช่วยประหยัดน้ำมัน การจะเลือกซื้อรถยนต์สักคันหนึ่ง นอกจากจะดูเรื่องเครื่องยนต์แล้ว อย่าลืมตรวจสอบระบบเกียร์และทำความเข้าใจระบบการทำงานให้ดี เพื่อที่คุณจะได้ใช้รถอย่างเต็มประสิทธิภาพ และช่วยยืดอายุการใช้งานของเกียร์ด้วยนั่นเอง
A standard automatic gearbox operates on exactly the same basic principle. Even so, as an alternative to there getting cables and rods to disengage the clutch and shift concerning gears, hydraulics and solenoids do the do the job with no direct enter from the motive force.
The belt or chain inside of a CVT connects the two pulleys. It is crafted from a large-strength substance, like metal or Kevlar, to deal with the significant torque produced by the motor.
In theory, a CVT contains a limitless amount of ratios since the diameter or even the pulleys is so variable. And that brings us to why a car would've a CVT.
Variable-diameter pulleys ought to always are available in pairs. One of several pulleys, often known as the push pulley (or driving pulley), is linked to the crankshaft with the motor. The driving pulley is also referred to as the enter pulley because it's in which the Electricity from the engine enters the transmission.
만약 그 시절에 이게 허용됐다면, 쉽게 말해 다른 팀들은 다 매뉴얼 또는 시퀀셜 기어를 사용하는데 이 팀만 오토매틱으로 주행했을 것이다.
Transmission failure can make abnormal noises even when the vehicle is in neutral. These Seems may sign lower transmission fluid amounts or mechanical have on and tear about the transmission factors.
CVT gearboxes can make a droning sound that retains constant, rather than expanding or reducing with motor pace. This may be a tad disconcerting for some motorists, and requires some finding used to.
Because of the interlocking surfaces, such a drive can transmit major torque and so has long been commonly used in industrial purposes. Nonetheless, the most pace is significantly decreased than other pulley-primarily based CVTs. The sliding plates will slowly but surely use over yrs of usage. Thus the plates are made extended than is needed, letting for more use before the chain have to be refurbished or changed. Continual lubrication is necessary and so the housing will likely be partially filled with oil.[nine][10]
The most common form Find Out More of CVT takes advantage of a V-belt which runs among two variable-diameter pulleys.[one] The pulleys encompass two cone-formed halves that move with each other and apart. The V-belt operates involving both of these halves, so the efficient diameter on the pulley is depending on the space concerning the two halves from the pulley.
Yet another downside of CVTs is they may be noisy in the event the engine is under significant load. It is because the transmission is consistently altering the pulleys and belt to keep the motor in its optimal ability assortment, which can result in a whining or droning seem. While some drivers may well not brain the noise, Many others may possibly discover it distracting or annoying.
The simplicity and stepless nature of CVTs make them an ideal transmission for several different devices and units, not just cars and trucks. CVTs are utilised For many years in power instruments and drill presses.
중고차 딜러들도 그냥 오토로 분류하고 일반 사람들도 오토로 알고 사용하는 경우가 많다.
For the duration of acceleration, in the event the automobile desires much more pace but fewer torque, the diameter from the secondary pulley decreases as its relocating sheave moves clear of the static sheave.
