ผู้ขับขี่ต้องเปลี่ยนเกียร์เองเมื่อขึ้นทางลาดชัน
These are definitely Alter Moi's figures, and certainly a simplification in the transmission planet, Nevertheless they'll function plenty of of an introduction. Check out the online video below through the Engineers Write-up for a more Visible backgrounder!
A CVT transmission, or constantly variable transmission, shifts seamlessly by way of an limitless choice of powerful gear ratios when you generate, answering the query of So how exactly does a cvt transmission function.
You’ll know from driving that in leading gear your motor only needs to do say 3000rpm for 100km/h – While 3000rpm in initially gear would see You simply at about 25km/h.
Elsewhere, Toyota's Hybrid Synergy Generate (HSD), which can be Utilized in hybrid products such as the Prius and Lexus IS 300h, utilizes a type of CVT gearbox as Section of the hybrid technique. This provides a split energy shipping and delivery so that the car's motor is possibly driving the wheels or sending electrical power towards the battery.
One cone is connected to the motor output shaft, when one other cone directs electrical power for the driveshaft and drive wheels. Equipment ratios improve because the pulleys go closer and additional aside, producing the chain or belt to move up and down The 2 cones' sides.

And so This is the place we finish up: the Change Moi staff has a number of working prototypes, Nonetheless they're now attempting to increase the fifty percent one million-odd bucks they will must do A different 12 months of R&D, integrate a prototype into that Yamaha T-Max, and acquire it across the expo circuit fishing for OEMs That may choose The thought up and force it by way of into a customer products.
I employed a drill push that labored on the identical principle. No stopping the equipment to maneuver the belt to a special pulley… turning the hand wheel along with the push allowed infinitely variable chuck r.
Steel Belt: Generally Utilized in CVTs for its sturdy and versatile style and design. Product of small steel elements with thin metal rings, these belts take care of a wide range of RPMs and perform perfectly While using the pulleys.
