What is Floating Gears?
The process of changing gears in a non-synchronous transmission—also known as floating gears, dead sticking, or bang shifting—usually occurs without depressing the clutch.
When they work correctly, floating gears will allow your car to shift gears faster and more easily. However, they can damage the gears if they are not properly engaged. Therefore, it is important to know what floating gears are, how they work, and how to prevent them from wearing out.
Timing Between Shifts
Floating gears are an easy way to make your travels easier, but they require a bit of finesse to get right. While they may seem complicated at first, they are actually easier to do once your brain has gotten used to the idea.
The secret to float-shifting is in the timing. For instance, if you are changing from four-low to six-low, you must first drop your RPMs by at least 200-300 rpm before you can go up a gear. This is because the transmission will want to move into a lower gear before the change.
For most truckers, it’s not enough to just make a gear change. They must also ensure they match their vehicle’s RPMs with the speed they’re traveling. If they don’t, they risk losing control of their vehicle. They also may experience unnecessary wear on their synchros, driveshaft, or transmission.
The best way to practice this method is to simply preweight your shifter. If you haven’t done this before, it can be difficult to know exactly when to apply the right amount of pressure to your shifter. This will reduce the chance of bumping your transmission.
The best way to practice this technique is to make sure you’re matching your RPMs with the speed of your vehicle. If you don’t, your vehicle may suffer from a smoky engine.
A great way to learn this technique is by watching YouTube videos. Many videos are out there explaining the secret to shifting gears without a clutch. Once you have learned a few tricks, you may be able to do it on your own.
The best way to practice this technique, especially if you’re new to driving, is to make sure you’re matching your vehicle’s RPMs with the speed of your vehicle.
Preventing Premature Wear and Tear on the Gears
Identifying the causes of premature wear and tear on the gears is crucial for preventing problems in your gearbox. Several failure modes are to consider, including gear surface wear, chemical action, foreign bodies, excessive load, and tooth break.
Gear surface wear refers to the mechanical and chemical action that occurs between the gear teeth. This wear includes abrasion, surface material displacement, and polishing. This can result in increased noise, efficiency downgrades, and gearbox failure.
Gear abrasion occurs when contaminants in the lubricant attack the gear surface. This occurs when metal debris from bearings or weld spatter is present in the lubricant.
Foreign bodies in the lubricant can also cause abrasion. They can be rust, sand, or other metallic debris. Lubricants should be kept clean to avoid contaminating the gears.
Foreign bodies can also affect the gearbox by causing bore wear. Bore wear can occur when the bearings rotate in the bores. In addition, a small misalignment in the gearbox can cause excessive load on the weaker teeth of the reducer. This can also cause erratic movement.
The amount of wear depends on the expected load, vibration, and noise. It may also occur because of improper drive design.
In extreme cases, gear pitting can result from surface overload. Spalling pits are wide in diameter and shallow in depth. Regular inspections can prevent this type of pitting.
The amount of wear and tear on the gears depends on the speed and application. In slow-speed applications, nitrided gears are recommended. In high-speed applications, the viscosity of the lubricant imposes practical limits on the gear’s operating conditions.
Abrasive wear, which is common in new systems, occurs when contaminates in the lubricant break down and eat away at the metal in the gears.
Proper Engagement of a Gear can Cause Damage to the Gears
Floating gears aren’t exactly cheap, so it makes sense to take care of them as often as possible. In fact, a good cleaning and lubrication routine is just as important as a good tune-up. Using the right products can do your job that much easier and keep your machine in mint condition.
A good lubrication routine will also go a long way in helping you avoid the most common mechanical failures. A properly lubricated gearbox will keep your machine in top shape and keep you out of the repair shop. It is also the best way to ensure your machine gets the treatment it deserves.
Double Clutching Prevents Gears from Grinding
Usually, when we talk about double clutching, we talk about using a clutch to shift gears. This technique is used on older vehicles and is used to prevent gears from grinding.
If you haven’t been driving trucks or haven’t used your vehicle for a while, you may not grasp what double clutching is. It’s not a complicated process. It takes some practice to get a good feel for it. Once you get a feel for it, it becomes more natural.
Double clutching is a great way to keep your gears from grinding. It’s also a good way to make sure that your transmission is not overly stressed. It also prevents your clutch from burning out. There are some downsides to double clutching, though. You might have to work both feet at the same time, which can be difficult for a new driver.
It’s also very important to use the correct amount of pressure. If you push the clutch too hard, your tires may slip. You should also pay close attention to the tachometer. The rise and fall of the tachometer are important for adjusting the gears. You also need to be aware of the road gradient and how it can affect how your vehicle accelerates during a shift.
You can learn to double clutch in a truck driving school. This is a skill that most trucking companies expect you to have. It’s also a skill that you will need to master in order to get your commercial driver’s license. Some jurisdictions require you to take a test on double clutching before you can obtain your CDL.
What does floating a gear mean?
Truckers refer to changing gears without applying the clutch as “floating the gears.” Truck drivers must therefore begin by reaching the same engine RPM and road speed needed for the gear they intend to shift into.
Is it better to use the clutch or float gears?
A more forgiving shift may result from applying the clutch before shifting gears, but if your timing is perfect, there is no benefit. Floating gears operate flawlessly when done correctly. No benefit can be derived from double gripping.
Can you float gears in a normal car?
Absolutely. When I drove a stick, the most recent being a 2009 Ford Focus that I had for more than 210,000 miles, I used to do this frequently. Changing gears without hitting the clutch pedal is referred to as “floating.”
Is it good to float gears?
Because the clutch and synchromesh are not engaged when choosing a gear, floating can reduce clutch and synchromesh wear. On the other hand, incorrect gear engagement (when the engine and transmission speeds aren’t matched) can harm the gears by physically grinding them together as a result of the speed difference.
Is clutchless shifting OK?
Don’t feel terrible if you’re having trouble; most new and old motorbikes with clutchless shifting work just fine. However, some motorcycles, such as those with large flywheels or wide-ratio gearboxes, don’t enjoy the technique.
