This gearbox from the 1930s lets you shift before you needed – Jalopnik

The pre-selector or self-changing gearbox may seem like a picturesque, quirky, quixotic piece of technology, but in its heyday it was less stressful on drivers than the non-synchro manual transmissions that were almost the only alternative. We naturally take how easy cars are to drive in modern times. Get in, press a button and we’ll go out. Heck, armies of engineers work tirelessly to make cars that drive themselves.

If in the 1930s you can detect one of the many hassle-riding with driving-that means you can detect an old automatic sturtle or owen magnetic, or you could get a car with a pre-selector gearbox, such as a cord 812 or Talbot AX65. If you have never managed a pre-selector gearbox (you probably not, unless you remember the McKinley murder), its effect may seem contraindative in the beginning. But the classic motorcycle hub shows how easy it is:

The most common pre-selector gearbox is the Wilson design found in Daimlers (the English) and lanchesters, with a liquid flywheel that behaves just like a couple inverter. You will find three pedals, such as in any car with a manual, but the clutch pedal is actually the “Make it in the gear I chose” pedal. We call it the pedal “gear activation”. Starting in neutral with the brake, switch on the gear choice first. When you are ready to go, release the brake and press the gear pedal. You are now first and you can accelerate. To go in the second place, place the lever in the next notch and press the pedal and it goes into gear. You could put the shifter in second place and drive around all day, but it will only shift if you press that pedal.

You can view Wilson Pre-Selector-Internals in action below, thanks to Vilas Motor Works. There are many things that the pre-selector does for you that would otherwise take a lot of finesse or muscles. In a car with a standard non-synchro gearbox, the driver must carefully double clutch to prevent them from avoiding the gears from the sliding connections until they become smooth cylinders. In addition, the switch lever needs a reasonable amount of arm intensity with relatively long throws.

Cars with pre-selector gearboxes have beautiful, cute Gated Shaged Shaged-Sized shifters on the column or elegant levers that move through the gears. There is no weight for them, and you can select the equipment that you like without having to match REV -Match. Of course you probably still have to switch on the gas feed, operate the choke, set the spark and all sorts of other old car processes that you nowadays only have to do on lawn mowers, but at least you should not remove gear shifts from the transmission case after a month of poor shifting.

However, do not get the impression that these gearboxes only helped bad double clutchers. They found houses in buses, tanks and racing cars, especially in Grand Prix before the Second World War. Reading accounts from modern drivers, such as the British Touringauto veteran Anthony Reid or historic Grand Prix driver Mark Gillies, pre-selector gearboxes become a lot of praise as soon as the clumsiness disappears. Told Reid Motorsport“From the perspective of a raced driver, you don’t want to worry about braking a gear lever in the most important phase of curves. On the right side in advance you place it in the gear you need and then you dip the ‘clutch’ in the normal way during the braking process and it is incredible.”

If the concept of selecting an acceleration in advance sounds a bit known, well, that is exactly what transmissions with double clutch do. It is only that, in the name of removing skills, choice and freedom of choice in the name of the convenience, computers and not the driver who controls the timing of the shift (although you can still damage it by your actions, of your foot of the brake on a slope or down during accelerating). All even gears get one coupling and strange gears the other, so that the transmission can seamlessly walk through the gears without thrust, so that EV-like slippery is given while the engine stays in its power band.

So things have come around the circle. Gear pre-selection is back. Sometimes the only thing needed for old technology to be reassed is better production techniques, superior implementation or computer supervision. Just look at EVs as a different example. The first record car of the land speed, the Jeantaud, was electric, with 39.2 km / h in 1898. It was only 110 years or so for electrical capacity to become a viable fossil-fuel alternative with cars such as the Nissan Leaf and Tesla Model S.

Then there is the Tucker ’48, yes, yes, in 1948. It is awesome, with so much cool technical progress. Originally, Tuckers 589-cubic inch flat-6s had to have 450 pound-foot torque and use hydraulically activated valves without traditional camshaft, which from before the camshaftless “Freeve verge” system of Koenigsegg with about 70 years before the production of a still a still-a-helin. However, what the production bowls received was a pre-selector transmission. Of course, this was nine years after GM debuted about the Hydra-Matic Automatic Transmission, but with the current proliferation of transmissions with double clutch, it seems that Tuckers were even more future-oriented than we thought.
