welcome centrifugal clutch !!for all cars!

Transmission Four-speed “Standrive” semi-automatic

Standrive (incorporating Newtondrive patents). From 2003 to 2005 I owned a Standard 10 fitted with the now-rare Standrive transmission, and I thought it was brilliant. Admittedly, I didn't have any problems with it, so didn't have to delve too deeply into it's workings, and if I had, perhaps I'd not be so keen now! In its day, they were not renowned for their reliability, and many small Standards fitted with this centrifugal clutch arrangement were converted to traditional, three pedal, layout. As such, surviving cars still running this curious arrangement are jolly thin on the ground. The only reason I sold my example was that I needed to make room for a new arrival, otherwise I'd definitely have hung on to it - I still have a nagging interest in finding a 10 pickup or Companion estate car one day - but I digress! While I owned it, I searched all over for material and information on the Standrive system, just in case things we wrong, then at least I'd have a fighting chance of being able to do something about it. Most of the material I found went with the car in 2005, but I still have this small leaflet, that introduced the system to a slightly sceptical motoring public. It is only a 2 page production, and details the key benefits of this 2 pedal arrangement. The clutch pedal went, and was replaced with a push button on top of the gearlever instead. This button activated the clutch, in order that another ratio could be selected while on the move - when stationary, there was no need to use the clutch button.

The info in the leaflet may be of interest to other owners of Standrive-equipped cars out there, which went as follows:

Outstanding Advantages The elimination of the clutch pedal - the most difficult control to operate... Reduces fatigue - especially in town driving Increases the safety factor Obviates faulty gear changes Makes engine stalling impossible Prevents transmission judder when starting or changing gear Simplifies learning to drive Furthermore, in designing the "Standrive" special consideration has been given to the varying styles of drivers. Slow or fast gear changes are both possible with the system used. Equally important is the fact that the "Standrive", unlike the fully automatic systems, permits the use of the gearbox for braking as on the conventional car. This obviously adds to the safety factor and ensures longer brake lining life. To sum up, with the new "Standrive" you have all the best features of the conventional gear change, but with the added advantage of smoother, safer, less fatiguing driving in all traffic conditions, and its simplicity of operation should particularly appeal to women drivers and all users of vehicles in conditions requiring frequent gear changes. How it works It consists of three major components: a centrifugal automatic clutch, a servo operated withdrawal cylinder and a control valve unit. The combination of these components allows gear changes to be made simply by moving the gear lever. The central gearlever is fitted with an electric switch incorporated in the gear lever head and operated by a push button. All that is necessary when making a gear change is to press the button on top of the gear lever and move the lever through the normal gate. The sequence of operations to drive the car away from stationary and bring it to rest again are as follows: With the gear in neutral and hand brake applied, the engine is started in the normal way. With the engine idling, the gear lever is moved into the required gear (for all normal starts 2nd is preferable). All that is then required to move off is for the engine to be accelerated, and as the drive is smoothly taken up the handbrake released in the usual way. To change up into the next higher gear, the gear lever is moved into the next appropriate gear, the electric switch on the gear lever being automatically depressed at the same time by the weight of the hand on the gear lever knob. The engine speed during this operation is automatically controlled to ensure a smooth change. To change to a lower gear, the foot is kept on the accelerator pedal and the gear lever is moved as before, but to the next lowest gear required. The change will be instantaneous and completely smooth and noiseless. The mechanism again automatically controlling the synchronisation of throttle and clutch. To stop, the accelerator is released and the brake applied. The car will stop with the engine idling. If a stop is of more than short duration the gearlever is placed in neutral ready to move into the starting position. Issued by The Standard Motor Company Ltd, Coventry, England. So there you have it, the official benefits of the 2 pedal transmission as outlined by the Standard factory in the mid/late 1950s. I think the installation in my car had been simplified slightly, in that the throttle wasn't automatically blipped during downchanges, which the above infers should happen. However a little blip on the throttle by the right foot kept the changes smooth enough, if not exactly seamless. I believe similar systems appeared on other cars of the fifties, for example on some Morris cars, where it was badged as the Manumatic.

But Take a look at old Saab 96 with a thing called "freewheel" Not shure of the translation on that, But the clutch on old Saab 96 anyway. A pretty cool thing for it's days. And yes, old mechanic of course.

Anyway just a thought about the Saab clutch since it's pretty uncommon knowledge specially out side of Sweden i guess.

Well there is clutch called recluse which is both centrifugal and a manual clutch.
old communist way of automatic. Same idea of clutch was used on Same Simson Schwalbe

The median American is pretty poor compared to the median European, but of course America is also the land of the filthy rich and widespread inequality so the mean is much higher. Western Europe is most certainly not poor, these are some of the richest countries on the planet.

so there is no need for cvt !!!!!

Exceptions In auto racing there is always exceptions this is a diaphragm clutch with centrifugal arms added ?

 research suggests that the performance of electric vehicle with a single-speed transmission can still be widely improved. The novel two-speed uninterrupted transmission consists of a single-row planetary, a centrifugal clutch, a brake, and two motor controlling clutch and brake. Changing the switch of clutch and brake can achieve two-speed uninterrupted gearshifts. Different from the traditional centrifugal clutch, a novel adjustable device is specifically designed to control the switch of clutch. Torque characteristics of clutch prototype are displayed. Some differences of the gearshift methodology are specifically designed to compensate for the characteristics of the electric traction motor and the adjustable centrifugal clutch. The specific simulation model is established according to the novel uninterrupted transmission prototype. The dynamic characteristics of the two-speed uninterrupted transmission system are analyzed. The higher utilization ratio of the traction motor power increases the efficiency of the traction motor with the novel two-speed uninterrupted transmission.
