เกียร์แต่ละประเภทนั้นมีข้อดี-ข้อเสียแตกต่างกันไป ทั้งเรื่องความทนทาน ค่าบำรุงรักษา รวมถึงเรื่องการช่วยประหยัดน้ำมัน การจะเลือกซื้อรถยนต์สักคันหนึ่ง นอกจากจะดูเรื่องเครื่องยนต์แล้ว อย่าลืมตรวจสอบระบบเกียร์และทำความเข้าใจระบบการทำงานให้ดี เพื่อที่คุณจะได้ใช้รถอย่างเต็มประสิทธิภาพ และช่วยยืดอายุการใช้งานของเกียร์ด้วยนั่นเอง
You could effortlessly swap involving equipment ratios while driving in a CVT transmission. Mechanical transmissions Have got a established variety of gears.
Your transmission difficulties are substantially decreased resulting from the use of hydraulics and elimination of friction-inclined points of Get hold of.
ผู้ขับขี่ต้องเปลี่ยนเกียร์เองเมื่อขึ้นทางลาดชัน
Concurrently using this motion of input pulley, feeding output pulley (sheave) also moves and go from the preset pulley which in turn moves the part of the v-shaped belt wrapped within the output pulleys in direction of the lessen cross-sectional Section of the conical output pulleys and wished-for velocity ratio is attained.
A CVT gearbox doesn't have many moving parts, so It can be relatively trusted. It's also mostly Utilized in small-energy programs, so autos functioning a CVT usually are reasonably unstressed. Assuming that the correct fluids are accustomed to lubricate the gearbox, so you stay with an everyday routine maintenance agenda, then a CVT box really should be no a lot less reliable than a standard car or manual.
Larger Expense. To get a supplied volume of ability-transmitting potential, a hydrostatic CVT is going to be dearer to create than an equivalent geared transmission. As well as the pump and motor(s), a hydrostatic method calls for the usage of an oil reservoir, piping and in many purposes, an oil cooler, this very last merchandise remaining required to dissipate the squander warmth that outcomes from hydrostatic electric power transmission's relatively lower performance.
Subsequently, some motorists could find the driving experience less partaking than with a standard computerized or handbook transmission.
Just before we enter into how a CVT will work, we have to to start with take a look at how a conventional gearbox operates and what its perform is. In essence, a gearbox enables the car’s wheels to turn in a slower pace as opposed to engine, and each person gear lowers the speed at which the engine turns.
This arrangement cuts down the load within the hydrostatic percentage of the transmission when during the ahead direction by transmitting a significant portion from the torque by means of far more efficient fixed gears.[21]
The system has two main parts: a driving pulley along with a driven pulley, related by a belt to transfer movement. Even so, it struggles to deal with higher torque in cars.
When starting from a halt, the transmission engages the launch equipment initially, then switches into the belt drive like a regular CVT. This launch gear is meant to make the car a lot more responsive and supply electric power additional instantly.
A repeatedly variable transmission technique can be a sort of automatic transmission where an arrangement of pulleys and belts manufactured it feasible for just a push to achieve n-range of constant equipment ratios in a variety (depends on the look).
Positively Infinitely Variable (PIV) chain drives are distinctive in the chain positively interlocks Using the conical pulleys. This is certainly attained by using a stack of anonymous numerous small rectangular plates in Every single chain link that will slide independently from facet-to-facet. The plates might be really slim, all-around a millimeter thick. The conical pulleys have radial grooves. A groove on a single aspect with the pulley is achieved having a ridge on another aspect and Hence the sliding plates are pushed forwards and backwards to conform towards the pattern, properly forming enamel of the proper pitch when squeezed concerning the pulleys.
