Most saving type of transmission

Most saving type of transmission

One of the most important questions that anyone planning to buy a car has to answer is: "which gearbox should I choose: automatic or manual?" Increasingly, car owners choose the automatic option, which is not surprising: driving a car equipped with an automatic is characterized by simplicity and convenience. Also, an important factor when choosing is the cost-effectiveness of use. In this article we will analyze, which of the units will allow the owner to save more on fuel.

Option # 1: Torque Converter automatic transmission

This is the most standard version of the automatic transmission, installed on most modern cars. The key feature of this type of transmission: the device does not have a clutch, its functions are performed by a Torque Converter. In terms of comfort of use, this option is probably the most convenient. However, in the process of using this type of gearboxes, the car owner faces a significant disadvantage – very high fuel consumption. Of course, car brands are constantly working to reduce this, but to date, not every manufacturer has managed to achieve acceptable results. As a rule, they try to solve the problem by installing quite complex devices – so-called blockers that require frequent and expensive maintenance. Accordingly, manufacturers install such devices only on the most modern and expensive cars.

Option # 2: CVT’s (also known as a stepless transmission, or variators)

The way CVT’s work is as simple as it is amazing. The mechanism consists of two shafts that have the shape of a cone. A belt or chain is stretched between them, giving traction. Thanks to this device, the gearbox and gear changes are incredibly smooth and unobtrusive. Owners of cars equipped with such devices note a certain unpleasant monotonous hum created by the gearbox, which, in principle, is not a huge disadvantage. Thanks to the complex variator system, the continuously variable transmission is one of the most cost-effective types of automatic transmissions.

Option # 3: Robotic gearbox

In the matter of fuel economy, the so-called “robots” are the undisputed leader. This is explained quite easily: there is almost no difference between the principle of operation of an ordinary manual transmission and a robotic automatic. The only difference between them is that the direct switching is performed not by the driver, but by a robotic system.

Of course, there is a difference between these two options. Gear changes performed by the “robot” occur with a significant hitch. Drivers who are used to other versions of gearboxes may initially react to this moment with some irritation. Nevertheless, this problem, apparently, will be fixed in the near future. Robotic gearboxes that take control of two clutch systems at once have already appeared on the market.

The principle of operation of such boxes is quite simple. Gears are divided into even and odd, and each of these categories is controlled by one of the clutch systems. This allows you to significantly increase productivity and reduce the pause between gear changes.

Finding quality transmission insights and reliable information is not an easy task for transmission specialists who are often either busy with transmission repairs or have their hands covered in oil after a transmission fluid change. All in all, we may be exaggerating a bit but finding these materials is a timely process indeed. We at have got it covered for you! There is a lot you can learn about transmission problem solutions and new transmission models being launched, we also try to interview transmission industry professionals so they can share some of their experience and stories with our readers. We have also included what we find to be events of interest for anyone related to the transmission industry: you check dates, venues, profile and more details on the upcoming industry events. We have got food for thought that you need!

In our last article we talked about frequency and how it relates to the mechanical response of a solenoid when Pulse Width Modulation (PWM) is used to control a solenoid. We discussed some of the theory, but what does this look like with an actual solenoid? How does frequency affect the response of a solenoid and how critical is matching the OEM frequency when driving a solenoid, especially when we start talking about testing and reclaiming solenoids.

There are so many problems with electrification development. No infrastructure, no stations to charge the batteries. And charging takes too long. Also, many cars don’t match the charger, many vehicles have to

In the last couple of articles, we used terminology relating to pressure control solenoids such as PWM, Frequency, and Duty Cycle. In this article I thought I would go into depth on what these terms really mean and how they relate to
