เกียร์แต่ละประเภทนั้นมีข้อดี-ข้อเสียแตกต่างกันไป ทั้งเรื่องความทนทาน ค่าบำรุงรักษา รวมถึงเรื่องการช่วยประหยัดน้ำมัน การจะเลือกซื้อรถยนต์สักคันหนึ่ง นอกจากจะดูเรื่องเครื่องยนต์แล้ว อย่าลืมตรวจสอบระบบเกียร์และทำความเข้าใจระบบการทำงานให้ดี เพื่อที่คุณจะได้ใช้รถอย่างเต็มประสิทธิภาพ และช่วยยืดอายุการใช้งานของเกียร์ด้วยนั่นเอง
Did Honda choose not to use the CVT in 1 technology of town design since it required to address some issues with this type of transmission?
When the car or truck is at relaxation, the launch gear engages. This engagement help with more quickly and much more successful acceleration from a end. As soon as the car reaches a velocity wherever the CVT can function easily, the launch gear disengages. The transmission shifts like a regular CVT.
Plus, the chain or belt in the CVT gearbox is under a great deal of strain, so It could be at higher chance of wearing out if connected to a superior horsepower engine. Are CVT gearboxes trusted?
Nevertheless, a CVT is effective very in a different way to a traditional automated gearbox underneath the skin. In fact, contacting a CVT a ‘gearbox’ is slightly deceptive as it doesn’t have any Bodily gears whatsoever.
Metal belt design and style HowStuffWorks The introduction of latest products tends to make CVTs all the more responsible and efficient. One among A very powerful advances is the design and advancement of steel belts to attach the pulleys.
Simplified control. Procedure with the comprehensive choice of forward and reverse speeds can be managed utilizing only one lever or possibly a foot pedal to actuate a diversion valve or variable-displacement pump.
The gearbox is linked to the wheels via shafts and a differential that turns the rotating movement as a result of ninety levels to get to the wheels.
Hydrostatic CVTs Both equally the pulley-and-V-belt CVT plus the toroidal CVT are samples of frictional CVTs, which operate by various the radius on the Speak to level among two rotating objects. There is another type of CVT, known as a hydrostatic CVT, that uses variable-displacement pumps to change the fluid stream into hydrostatic motors.
We investigate, exam, evaluate, and propose the most effective products. Tech experts study the content for accuracy. To obtain more specifics of our means of performing things, Find out more about our method here. We may perhaps have a commission if you buy by clicking on the link.
CVTs perform through the use of a procedure of pulleys and belts to vary the gear ratios constantly, letting the motor to function at a continuing RPM even though the motor vehicle moves at various speeds.
풀리 지름만 조절하면 넓은 기어비 범위를 구현할 수 있고 기어 단수의 제한을 받지 않으므로 엔진 회전수를 비교적 정밀하게 제어할 수 있어 연비도 좋다.
Inside a hydrostatic CVT, the efficient "gear ratio" in between the engine as well as driving wheel(s) is the results of a distinction between the pump's displacement—expressed as cubic inches or cubic centimeters for each revolution—as well as the anonymous motor's displacement.
With all in their positive aspects, CVTs do have some shortcomings. In the United States, they remain attempting to beat an image trouble. The Subaru Justy, by way of example, was referred to as a gutless micro-motor vehicle. Typically, belt-travel CVTs had been minimal in the amount of torque they might tackle and had been much larger and heavier than their automatic and guide counterparts.
