What is torque converter

 A torque converter is a fluid coupling device found in automatic transmission vehicles that transfers rotational power, or torque, from the engine to the transmission. It allows the engine to continue running at idle speed while the vehicle is stopped, and also smooths out power delivery during gear changes. The torque converter uses a turbine and impeller to transfer power, which are connected by a fluid. The turbine is connected to the engine, and the impeller is connected to the transmission. As the engine's torque increases, the turbine spins faster, causing the fluid to flow and transfer power to the impeller. This allows the transmission to engage smoothly, without the jerking or hesitation that would occur with a mechanical clutch.



The torque converter was invented by Alfred H. Rzeppa in the early 1930s. Rzeppa, who was a transmission engineer at the Hydra-Matic Division of General Motors, developed the torque converter as a means of smoothly transferring power from an engine to a transmission in an automatic transmission system. The torque converter uses a fluid-coupling mechanism to transfer power, which allows for smooth and efficient operation.

Maintenance of torque converter

Torque converters require little maintenance, as they are sealed units and do not require oil changes or other routine upkeep. However, it is important to make sure that the transmission fluid is at the correct level and is in good condition, as the torque converter relies on this fluid to function properly. In addition, it is important to have any leaks or other issues with the transmission system repaired as soon as they are identified, as these can lead to damage or failure of the torque converter. If you suspect any problems with your torque converter, it is best to have it inspected by a professional mechanic.






















Torque converters have several advantages, including:

  1. Smooth engagement: Torque converters allow for a smooth transfer of power from the engine to the transmission, which can make for a more comfortable driving experience.

  2. Engine braking: When the accelerator pedal is released, the torque converter can provide engine braking, which can help to slow the vehicle down.

  3. Better launch characteristics: Torque converters can provide better launch characteristics than a clutch-based system, allowing for quicker acceleration from a stop.

  4. Automatic transmissions: Torque converters are typically used in automatic transmissions, which can be more convenient for some drivers.

  5. Towing capability: Torque converters can provide improved towing capability as it can handle high torque loads and provide additional power to move heavy loads.

  6. Improved fuel efficiency: Torque converters can improve fuel efficiency in vehicles that use them.

What is transmission charging pump

Image
  A transmission charging pump is a component in a vehicle's transmission system that pumps fluid through the transmission to lubricate and cool the gears and other internal parts. It is typically driven by the transmission's output shaft and helps maintain the proper pressure and flow of transmission fluid. The inventor of the transmission charging pump is not specified, as the technology has been developed and improved upon over time by multiple individuals and companies. The first transmission charging pump was likely developed as part of the development of the first automobiles, which began in the late 19th century. It's important to note that the concept of the transmission charging pump may have been invented by multiple inventors at the same time or independently. USES OF TRANSMISSION CHARGING PUMP Transmission charging pumps are used in the automotive industry to increase the pressure in a vehicle's transmission system. This increased pressure helps to improve t...

What is supercharger

Image
  A supercharger is a device that increases the pressure of air entering an internal combustion engine. This results in a higher density of air, allowing more fuel to be burned and increasing the engine's power output. Superchargers can be mechanical or electrical, and are commonly used in performance vehicles to increase horsepower and torque. Some vehicles come with a factory-installed supercharger, while others can be retrofitted with aftermarket superchargers. In 1849, G. Jones of Birmingham, England began manufacturing a   lobe pump   compressor to provide ventilation for coal mines. [14]   In 1860, the   Roots Blower Company   (founded by brothers Philander and Francis Marion Roots) in the United States patented the design for an air mover for use in   blast furnaces   and other industrial applications. This air mover and Birmingham's ventilation compressor both used designs similar to that of the later   Roots-type supercharger...
