Semi-automatic transmission is a system that makes use of electronic sensors, processors and actuators for gear shifting. The system removes the need of a clutch pedal required for gear changing. This system is widely used in the automobile industry.
Types of Semi Automatic Transmission Direct Shift Gearbox Dual Clutch Gearbox The system allows for only forward and backward shift into higher and lower gears. It does not make use of the traditional H-pattern, normally used in automobiles. The system is also equipped with sensors that sense the direction of the shift. The input, combines with the sensor placed in the gearbox senses the current speed and selected gear. The unit also determines the torque required for smooth functioning. The system also reduces fuel consumption significantly.
Automatic Transmission
Automatic transmission is a type of gearbox, especially used in the automobile industry for changing gear ratios automatically. It does not require manual shifting of gears. The gearbox has a set of selected gear range.
The system is hydraulically operated and makes use of a torque converter and a set of planetary gears.
Parts of an Automatic Transmission SystemAn automatic transmission consists of the following parts: Torque Converter: It is a device connecting engine and transmission. The instrument takes place of a mechanical clutch, allowing the engine to remain running. A torque converter that provides a variable amount of torque multiplication at low engine speeds. Planetary Gearbox Set: The bands and clutches of this gear set are actuated with the help of hydraulic servos controlled by the valve body, thereby providing two or more gear ratios. Valve Body: The system receives pressurized fluid from a main pump operated torque converter. The pressure coming from this pump is regulated used to run a network of spring-loaded valves, check balls and servo pistons. The valves make use of pump pressure and the pressure from a centrifugal controller on the output side. Use of Automatic Transmission Automobiles Forklift trucks Lawn mowers

Information on Gearbox
Gearboxes are used in almost every industry right from power to marine, and also include agriculture, textile, automobiles, aerospace, shipping etc. There are different types of gearboxes available for varying uses. These gearboxes are constructed from a variety of materials depending on their end use and the kind of industry they are being used in. The product has numerous industrial applications for providing high torque and smooth speed reductions. These gearboxes are also manufactured keeping certain specifications in mind, which will also vary depending on the application.
