 Zeroshift
This is the next generation technology that we are looking forward to, its a clutchless transmission system, and much like an automatic it will change gears...but in a way so that it upchanges at a time when the there is no torque loss, and also because there is no torque loss, you can expect better mileage as compared to a conventional automatic or even a manual, and the good part is that its cheap and relatively simple and so very reliable. Its currently in its latter development phases but it stirred up quite a storm and is so flexible that experts say that in ten years time every car will have a transmission based on this very principle..it said to be easier on the engine and the adjoining transmission!  The first generation Zeroshift transmission was pneumatically operated and used six drive elements — specially contoured metal ‘bullets’ — to engage and disengage the drive gears in a similar manner to dog clutches, replacing the synchromesh found in a conventional gearbox. In the second generation system, these have been replaced by a pair of interlocking rings, each incorporating the three drive elements in a single forged component and operated by shift forks. When shifting from neutral, ring one is engaged to take up drive while ring two is engaged within a few degrees of revolution to take up backlash. The next shift is made with ring two taking up the drive and ring one taking up the backlash. As ring two is unloaded during the change, it requires less than one-twentieth the axial force required by a conventional synchromesh. The control system, also developed and calibrated by Zeroshift, coordinates gearshift actuation, engine management and clutch operation to provide full control over the driveline during gear shifting. Refinement and durability have been further improved through careful design of the working surfaces. One side of the drive element has a retention angle to take up the drive, while the opposite side has a ramp face to smoothly disengage drive. At this point, we’re in two gears at once and the ’box ought to be destroying itself. Instead, the higher gear spins faster and its ‘clamping force’ on the previous gear’s bullets dissipates, leaving it free to move away under the spring’s power.  |
