Zeroshift - New Transmission Technology - of 21st Century

Kiwi inventor Bill Martin has developed a gearbox .
The last big breakthrough in automatic gearboxes was in 1928 with synchromesh.

The Zeroshift transmission can shift gears in zero seconds and do it seamlessly by using electronically controlled actuators and an automated single dry clutch. These actuators also can be powered by either air or hydraulic pressure, which greatly expands the type of vehicle applications.

The secret behind the Zeroshift concept is the elimination synchro rings, which are replaced bydog clutches. These dog clutches automatically upshift and downshift the transmission

Automatic Transmission in Automobiles (Cars)

How Automatic Transmissions Work


Many of the mechanisms and technologies that are used in the modern automatic transmission system  were already in use in manual transmissions. Transmission bands and planetary gears were used in the manual transmission for the Ford Model T and Model K (1906). Fluid coupling was used by General Motors in 1937.

These technologies were first developed in the early 1900s in Germany for use in marine applications.

Semi-automatic transmissions appeared in a major automotive brand in 1937. With planetary gears and a conventional friction clutch, these transmissions allowed easier shifting and required less driving skill. Cadillac and Oldsmobile issued models with  automatic transmission through 1939. Buick used it  in 1938. The AST never inspired the driving public and was not supported by large sales numbers.

The 1948 Oldsmobile was the first model to use a true automatic transmission. The Hyrdo-Matic was developed by GM engineer, Earl Thompson,  The Hydro-Matic went through continual upgrading and refinements through 1955. But, the basic design and theory used were consistent throughout its remarkably long life span.  Other auto manufacturers purchased and used the Hydro-Matic. These included:

Hudson Nash Rambler
Frazer Nash Kaiser
Willys Lincoln
Rolls-Royce Bentley

General Motors replaced the Hydro-Matic in 1956 with the Jetaway. The "Jet" was not a roaring success and quickly gave way to the Turbo Hydromatic.

Chrysler's Fluid Drive was introduced in 1939, but this was really a manual transmission that used a fluid coupling to make shifting easier. Chrysler first produced a semi-automatic transmission in 1942 and was late in developing their own true automatic transmission, introducing the two-speed PowerFlite in 1954.

BorgWarner engineered the first automatic transmission used by Ford, introduced in 1950.

Mercedes introduced their first automatic in 1962. Rolls Royce's 1955 intro was with GM's Hydro-Matic. Daimler first used a BorgWarner 4-speed in 1962.

Through the 1980s changes and advances occurred quickly. Special features seemed to be the primary focus of transmission designers.

Options included:

     Manual-or-automatic shifting - allowed      drivers to take control of the shifting when      they wished

     Push-button shifting - a Chrysler Torqueflite      innovation that used a two-cable mechanism

     Edsel's Teletouch shifting - buttons in the      middle of the steering wheel that operated      an electric shift motor

     Economy-performance settings - the      driver could reset with the push of a button

     Over-drive in 3, 4, and 4-plus-overdrive      configurations

     Hill-hold - prevented the vehicle from      rolling backwards at idle on an upgrade

     Ignition lock coupling - anti-theft feature

In the late 1980s, use of computers in cars started. and resulted in the introduction of electronic controls for automatic transmissions. Solenoids and sensors integrate with multiple onboard computers to control shifting and gear ratio in any imaginable scenario.

Honda's Hondamatic transmission is unique in that it is an automatic that does not use planetary gears. Gears slide on parallel shafts. The Hondamatic is similar neither to other automatic transmissions nor to manual transmissions.

Five-speed, six-speed, seven, and even eight-speed transmissions are currently being used in automobiles. Such technologies are being tested and deployed in an effort to improve economy and efficiency.

CVTs provide continuous torque at engine peek-performance speeds

Transmission research and development is currently leaning toward Automated Manual Transmission technologies. Suzuki has come out with successful technology and is using it in a Indian model Celerio.

Celerio Maruti Suzuki 2014 Model

A new small car, with some variants priced below Rs 4 lakh, is on its way from February 2014 from  Maruti Suzuki India's stable. . Called Celerio, this car  will be a one litre petrol car in two transmissions - manual and automatic. This car will probably deliver mileage of over 20 kmpl. The transmission in automatic mode is called automatic manual transmission ( More details  )

Suzuki Motor Corp, took about three years to develop the technology which has raised the fuel efficiency of the automatic variant to almost equal that of the manual transmission vehicle.  Normally fuel efficiency of automatic transmission is less than that of manual transmission.

Typically, the automatic variant of any car is pricier from the manual transmission variant by about Rs 1 lakh but in the case of Celerio, the price difference between the two variants would be "much less".

The Celerio will be pitched against the likes of Hyundai's Grandi10 and Honda's Brio, whose automatic versions are priced at Rs 6.04 lakh and Rs 6.19 lakh, respectively (ex-showroom, Delhi).

The Celerio will offer a fuel efficiency of 23.1 km per litre and will be offered in six petrol variants - four with Manual transmission and two with Auto Gear Shift.

Hydrogen Fuel Cell Cars

Toyota is ready to sell fuel cell cars in 2015

A four-seat sedan, the car is only called Fuel Cell Vehicle (FCV) for now. The FCV’s range is similar to electric cars, but with the advantage that fill-ups will only take a few minutes. Initially, the FCV will be sold in California where the state has made a commitment to having over one hundred hydrogen filling stations within a decade.

Top 10 Strategic Technologies in Information Technology for Year 2014

Gartner defines a strategic technology as one with the potential for significant impact on the enterprise performance in the next three years. Significant impacts include a high potential for disruption to IT or the business, the need for a major dollar investment, or the risk of being late to adopt.

A strategic technology may be an existing technology that has matured and/or become suitable for a wider range of uses. It may also be an emerging technology that offers an opportunity for strategic business advantage for early adopters or with potential for significant market disruption in the next five years. These technologies impact the organization's long-term plans, programs and initiatives.

The top 10 technologies should be factored into their strategic planning processes of IT companies and IT intensive companies. This does not necessarily mean adoption and investment in all of the listed technologies by all companies, but companies should evaluate them and  make deliberate decisions about using them during the next two years.
